  • the aerosol generating matrix segment requires more energy to generate a larger amount of smoke in the initial stage of heating, and the energy supply of the heating component in the initial stage is delayed and the energy accumulation is small, resulting in the aerosol generating matrix segment generating limited aerosol in the front section of puffing, and more sufficient aerosol generated in the middle and late sections of puffing; when the density of the aerosol generating matrix segment is relatively low, the heat capacity is small, the effective material load is relatively low, and the porosity inside the aerosol generating matrix segment is high.

具体实施方式
在本申请实施例的描述中，需要说明的是，术语“第一方向”等指示的方位或位置关系为基于附图2所示的方位或位置关系，这些方位术语仅是为了便于描述本申请实施例和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请实施例的限制。
本申请实施例提供了一种气溶胶生成基质段10，请参阅图1至图3，该气溶胶生成基质段10包括多个并行排列成束的混合密度基质条11，各混合密度基质条11在气溶胶生成基质段10的相对两端之间延伸。
多个并行排列的混合密度基质条11沿第一方向延伸，也就是说，混合密度基质条11的延伸方向为第一方向。第一方向与气溶胶生成基质段10的中心轴线方向之间的夹角不大于10度。也就是说，由于混合密度基质条11的制造精度、各混合密度基质条11的成束工艺等原因，可能会出现部分混合密度基质条11的延伸方向稍微偏离气溶胶生成基质段10的中心轴线方向，或者混合密度基质条11的部分出现弯曲，只要混合密度基质条11大致沿气溶胶生成基质段10的一端延伸至另一端，均可认为混合密度基质条11在气溶胶生成基质段10沿第一方向延伸。
示例性地，第一方向可以与气溶胶生成基质段10的中心轴线方向平行，即第一方向与气溶胶生成基质段10的中心轴线方向之间的夹角为0度。
各混合密度基质条11沿第一方向的一端可以位于或靠近气溶胶生成基质段10的相对两端中的其中一端，各混合密度基质条11沿第一方向的另一端可以位于或靠近气溶胶生成基质段10的相对两端中的另一端。
并行排列是指以平行于第一方向的平面为投影面，各个混合密度基质条11的投影至少部分重叠。也就是说，各个混合密度基质条11并不是沿第一方向依次首尾连接，而是大致并列。
请继续参阅图2，定义垂直于气溶胶生成基质段10的中心轴线的面为横截面，混合密度基质条11具有沿第二方向排布的第一密度区域111和第二密度区域112，第一密度区域111的密度小于第二密度区域112的密度，其中，第二方向与混合密度基质条11的延伸方向垂直。即，混合密度基质条11具有沿横截面排布的第一密度区域111和第二密度区域112。
第一密度区域111和第二密度区域112的密度均可以根据需要进行设计，示例性地，第一密度区域111的密度可以为400mg～1300mg/cm3(包括端点值)，比如400mg/cm3、500mg/cm3、700mg/cm3、900mg/cm3、1200mg/cm3、1300mg/cm3等。
示例性地，第二密度区域112的密度可以为900mg～2000mg/cm3(包括端点值)，比如900mg/cm3、1200mg/cm3、1500mg/cm3、1800mg/cm3、2000mg/cm3等。
同一个混合密度基质条11中的第一密度区域111和第二密度区域112的体积比可以根据需要进行设计，示例性地，同一个混合密度基质条11中的第一密度区域111和第二密度区域112的体积比可以为1：10～5：1(包括端点值)，比如1：10、1：5、2：3、1:1、2：1、3：1、5：1等。
示例性地，请继续参阅图1，气溶胶生成基质段10可以设置包装层13，包装层13卷绕形成容纳空间，所有混合密度基质条11容纳于容纳空间内。
包装层13可以呈中空管状，所有混合密度基质条11容纳于包装层13的容纳空间内，包装层13也可以是接装纸，所有混合密度基质条11通过接装纸复合成一体结构。包装层13可以对混合密度基质条11起到定型和保护作用。
气溶胶生成基质段10的填充率可以根据需要进行设计，示例性地，气溶胶生成基质段10的填充率可以为40％～90％(包括端点值)，比如40％、50％、60％、70％、80％、90％等。
需要说明的是，如果气溶胶生成基质段10中只有混合密度基质条11，则气溶胶生成基质段10中的填充率是指所有混合密度基质条11在气溶胶生成基质段10中的填充率，如果气溶胶生成基质段10中除了混合密度基质条11之外，还有其它的基质条，则气溶胶生成基质段10中的填充率是指所有基质条在气溶胶生成基质段10中的填充率，即所有基质条的体积之和与容纳空间的容积的占比。
混合密度基质条11的具体结构在此不做限制，示例性地，一实施例中，混合密度基质条11可由雾化介质本身制成，例如由发烟味香料介质制成。另一些实施例中，混合密度基质条11也可以包括基体以及设置在基体上的雾化介质，基体例如可以是耐高温的碳纤维、针叶木浆纤维、阔叶木浆纤维、竹纤维、棉纤维、麻纤维的一种或者多种，如此，通过设置基体，既可以提高混合密度基质条11的强度，还可以承受一定程度的高温而不产生异味。
混合密度基质条11的具体成分在此不做限制，示例性地，一实施例中，混合密度基质条11可包括植物成分、助剂成分、发烟剂成分、粘合剂成分等。
在一实施例中，植物成分为烟叶原料、烟叶碎片、烟梗、烟末、香味植物等经破碎处理后形成的粉末中一种或多种组合。植物成分为制品香味的核心来源，植物成分中的内源物质，如烟碱通过雾化进入人体血液，促进脑垂体产生多巴胺，从而获得生理满足感。
在一实施例中，植物成分可以包括烟草、茶叶、茶梗、蒲公英、桉树、丁香、桂皮、姜黄、菌类、胰岛素木，黄芪、酸枣仁、兵豆、葛根、茴香、迷迭香、八角、金银花、菊花、玫瑰花、金盏花、艾叶、橄榄、人参、西洋参、绿豆、红豆、陈皮、坚果壳、百合、咖啡、沉香、薄荷、山楂、甘草、可可、木耳、莲子、荷叶、凉姜、生姜、苦荞、麦麸中的一种或多种，植物成分在气溶胶基质中的质量占比可以为20％-80％(包括端点值)。
在一实施例中，助剂成分可以为无机填料、润滑剂、乳化剂中一种或多种组合。其中，无机填料包括重质碳酸钙、轻质碳酸钙、沸石、凹凸棒石、滑石粉、硅藻土中一种或多种组合。无机填料可以为植物成分提供骨架支撑作用，同时无机填料还具有微孔，可以提高植物成分成型后的壁材孔隙率，从而提高气溶胶释放率。
润滑剂包括小烛树蜡、巴西棕榈蜡、虫胶、向日葵蜡、米糠、蜂蜡、硬脂酸、软脂酸中一种或多种组合。润滑剂可以增加颗粒的流动性，减少颗粒相互间的摩擦力，可使颗粒分布的整体密度较为均匀，也能降低模具成型所需的压力，降低模具的磨损。
乳化剂包括聚甘油脂肪酸酯、吐温-80、聚乙烯醇中一种或多种组合。乳化剂在一定程度上能够减缓香味物质在储存过程中的损失，增加香味物质的稳定性，提高产品的感官品质。乳化剂(也可称为表面活性剂)可降低混合体系中水溶性和水不溶性组分的界面张力，并在微滴表面形成较坚固的薄膜或由于乳化剂给出的电荷而在微滴表面形成双电层，阻止微滴彼此聚集，而保持均匀的乳状液。两种不相融组分乳化均质可以提高制品质量的一致性。
发烟剂成分的作用是在加热时可以产生大量蒸汽，从而提升发烟制品的烟雾量。在一实施例中，发烟剂例如可以包括：一元醇(如薄荷醇)；多元醇(如丙二醇、三乙二醇、1,3-丁二醇和甘油)；多元醇的酯(如单乙酸甘油酯、二乙酸甘油酯或三乙酸甘油酯)；单羧酸；多元羧酸(如月桂酸、肉豆蔻酸)或多元羧酸的脂肪族酯(如十二烷二酸二甲酯、十四烷二酸二甲酯、赤藻糖醇、1,3-丁二醇、四乙二醇、柠檬酸三乙酯、碳酸亚丙酯、月桂酸乙酯、特瑞克汀(Triactin)、内消旋赤藻糖醇、二乙酸甘油酯混合物、辛二酸二乙酯、柠檬酸三乙酯、苯甲酸苯甲酯、苯基乙酸苯甲酯、香草酸乙酯、甘油三丁酸酯、乙酸月桂酯)中一种或多种组合。
在一实施例中，粘合剂成分为天然植物提取，非离子化改性粘性多糖，包括罗望子多糖、普鲁兰多糖、海藻多糖、刺槐豆胶、瓜尔胶、木葡聚糖中的一种或多种组合。粘合剂通过与制品组分材料界面润湿而紧密接触，产生分子间的吸引力，从而起到粘结组分材料的粉体、液体等的作用。同时选用天然植物提取、非离子该性粘合剂，可避免胶体改性带来的甲醇、甲醛、丙烯醛等有害物质的释放，提高制品的安全性。
混合密度基质条11可以为颗粒结合体，颗粒结合体是一种重组烟草介质，例如是含发烟剂、烟草等成分的重组烟草介质。混合密度基质条11为一体式结构，例如，可以通过注塑、压塑或挤出工艺成型出的一体式结构。其中挤出成型是指将原料混合物加入到挤出机中，物料通过挤出机料筒和螺杆间或活塞的作用，被螺杆或活塞向前推送，连续通过机头而制成各种截面制品或半制品的一种加工方法。
示例性地，可以将两种密度不同的基质物料分别注入挤出机的两个独立的挤出通道中，两个挤出通道中的基质物料同时从挤出机的同一个挤出口挤出，再通过干燥定型得到混合基质条，定型后的各混合密度基质条11先进行定向排列，再通过卷棒形成气溶胶生成基质段10。
由于混合密度基质条11为颗粒结合体，因此，由多个混合密度基质条11形成的气溶胶生成基质段10在受热抽吸或停止受热后均为一体式介质，不易出现崩解掉落的现象，解决了现有技术中的薄片状、丝状或散状颗粒的气溶胶生成基质段10所出现的如薄片松脱，丝状成分、颗粒成分脱落，不易清洁的问题。
混合密度基质条11可以是沿直线延伸的直线形，也可以是沿延伸方向的至少部分区域的曲率不为0的曲线形。
混合密度基质条11的横截面(即与混合密度基质条11的延伸方向垂直的截面)的形状不做限制，示例性地，混合密度基质条11的横截面的形状可以是多边形(包括但不限于三角形、棱形以及图7所示的方形等)，图4所示的圆形，图8所示的椭圆形，图9所示的花瓣形等，花瓣形是指由圆形以及环绕在圆形周侧的多个弧形组合形成的封闭图形。除此之外，混合密度基质条11的横截面的形状还可以是腰圆形、齿轮形和异形等，腰圆形是指过圆心将一个圆平分成两个半圆弧且相互反向平移，用二根等长平行线将两个半圆弧的端点连接而形成的封闭图形，而异形是指前面所列举的形状之外的其它对称或非对称的形状。
气溶胶生成基质段10中的混合密度基质条11可以全部采用相同的横截面形状，也可以采用两种或两种以上不同的横截面形状。
混合密度基质条11的横截面尺寸可以根据需要进行设计，其中，横截面尺寸是指用于定义混合密度基质条11的横截面的外轮廓的尺寸，比如，如果混合密度基质条11的横截面为圆形，则横截面尺寸为混合密度基质条11的横截面的直径，如果横截面形状为其它形状时，可以认为横截面尺寸为等效直径或多边形的边长尺寸，比如，如果混合密度基质条11的横截面为方形，则横截面尺寸为混合密度基质条11的横截面的最大长度，如果混合密度基质条11的横截面为圆形和方形之外的其它形状，则横截面尺寸为混合密度基质条11的横截面的最大尺寸，即横截面的外轮廓上，距离最远的两个点之间的距离。
示例性地，混合密度基质条11的横截面尺寸可以为0.4mm～7mm(包括端点值)，以横截面形状为圆形为例，直径为0.4mm～7mm(包括端点值)，比如0.4mm、0.8mm、1mm、1.2mm、1.5mm、2mm、3mm、3.5mm、4mm、5mm、7mm等。
较优选地，混合密度基质条11的横截面尺寸可以为0.5mm～3.5mm(包括端点值)，例如直径为0.5mm～3.5mm(包括端点值)，更优选地，混合密度基质条11的横截面尺寸可以为0.8～1.5mm(包括端点值)，例如直径为0.8mm～1.5mm(包括端点值)。
图1和图2所示的混合密度基质条11为等截面结构，也就是说，混合密度基质条11任意位置处的横截面的形状以及尺寸均相同。采用等截面结构可以便于加工制造混合密度基质条11。
在另一些实施例中，混合密度基质条11也可以为变截面结构，变截面结构是指混合密度基质条11至少有一个位置处的横截面的形状或尺寸与其它位置处的横截面的形状或尺寸不同。
气溶胶生成基质段10的形状也不做限制，示例性地，气溶胶生成基质段10可以是柱状。柱状的气溶胶生成基质段10的横截面的形状也可以是多边形(包括但不限于三角形、棱形以及方形等)、椭圆形、圆形、腰圆形和异形等。
本申请实施例还提供了一种气溶胶生成制品，请参阅图10至图12，该气溶胶生成制品包括功能段20、外包裹层(图未示出)和本申请任一实施例所提供的气溶胶生成基质段10。
功能段20设置在气溶胶生成基质段10沿第一方向的一端，功能段20包括降温段21和过滤段22，降温段21位于过滤段22与气溶胶生成基质段10之间。外包裹层包裹在功能段20和气溶胶生成基质段10的外周侧。
气溶胶生成制品用于与具有加热组件的气溶胶生成装置配合使用，具体地，气溶胶生成装置的加热组件对气溶胶生成基质段10进行加热，使得气溶胶生成基质段10释放气溶胶。用户逐口抽吸气溶胶，也就是说，用户抽吸一口气溶胶，停止抽吸，再抽吸下一口气溶胶，如此，用户间歇性地抽吸。抽吸的前段是指气溶胶生成基质段10初始使用的时段，抽吸的前几口对应抽吸的前段，例如1-5口；抽吸的后段是指气溶胶生成基质段10接近气溶胶释放完全的时段，抽吸的后几口对应抽吸的后段，例如最后1-5口。抽吸的前段和后段分别是指气溶胶生成基质段10的使用生命周期内的前期和后期。抽吸的中段则是指前段和后段之间的抽吸时段。
加热组件的加热方式有多种，示例性地，加热方式包括中心加热和周圈加热，中心加热方式是指加热组件插入气溶胶生成基质段10内部对气溶胶生成基质段10从内到外进行烘烤加热。周圈加热方式是指加热组件设置在气溶胶生成制品的外围，以对气溶胶生成基质段10进行从外到内的烘烤加热。这些加热方式具体可为电阻加热、电磁加热、红外加热、微波加热、激光加热等，在此不做具体限定。
降温段21设置在过滤段22与气溶胶生成基质段10之间，以用于在过滤段22对气溶胶进行过滤之前，对气溶胶进行降温处理，以降低气溶胶的温度，改善用户吸食气溶胶时的“烫嘴”现象。
降温段21的材料包括但不限于PE(polyethylene，聚乙烯)、PLA(Polylactic acid，聚乳酸，又称为聚丙交酯)、PBAT(butyleneadipate-co-terephthalate，聚对苯二甲酸-己二酸丁二醇酯)、PP(Polypropylene，聚丙烯)、醋酸纤维、丙烯纤维材料中一种或多种组合。
过滤段22的材料包括但不限于PE、PLA、PBAT、PP、醋酸纤维、丙烯纤维材料中一种或多种组合。
降温段21和过滤段22的材质可以相同，也可以不同。
需要说明的是，气溶胶生成制品依靠气溶胶生成基质段10产生气溶胶，功能段20不产生气溶胶。
外包裹层的材质不限，例如，包括但不限于纤维纸、金属箔、红外辐射层、金属箔复合纤维纸、聚乙烯复合纤维纸、PE、PBAT等材料中的一种或多种组合。
外包裹层可以呈中空管状，气溶胶生成基质段10和功能段20可以依次排列在中空管状的外包裹层中，外包裹层也可以是接装纸，气溶胶生成基质段10和功能段20通过接装纸复合成一体结构。
示例性地，气溶胶生成基质段10沿第一方向的长度尺寸可以为气溶胶生成制品沿第一方向的长度尺寸的20％～80％(包括端点值)，比如20％、40％、50％、80％等。
示例性地，降温段21沿第一方向的长度尺寸可以为气溶胶生成制品沿第一方向的长度尺寸的25％～65％(包括端点值)，比如25％、30％、50％、65％等。
可以理解的是，在用户的抽吸过程中，气溶胶生成基质段10产生的气溶胶是沿第一方向向过滤段22流动。
相关技术中，薄片状、丝状、散状颗粒、灌装一体的多孔柱状等形态的气溶胶生成基质段的密度都较为均匀，这些气溶胶生成基质段难以在密度上进行差异化设计与控制。但是，对于这些密度较为均匀的气溶胶生成基质段，当气溶胶生成基质段的密度相对较高时，热容较大，有效物质负载相对较高，气溶胶生成基质段内部的孔隙率较低，气溶胶生成基质段在加热初始阶段需要较多的能量才能产生较大的烟雾量，而加热组件在初始阶段的能量提供有所滞后且能量累积较少，从而导致气溶胶生成基质段在抽吸前段产生的气溶胶有限，而在抽吸中后段产生的气溶胶较为充足；当气溶胶生成基质段的密度相对较低时，热容较小，有效物质负载相对较低，气溶胶生成基质段内部的孔隙率较高，气溶胶生成基质段在加热初始阶段需要较少的能量就能产生较大的烟雾量，出烟快，从而导致气溶胶生成基质段在抽吸前段产生的气溶胶较为充足，而在抽吸中后段产生的气溶胶出现明显衰减。也就是说，密度较为均匀的气溶胶生成基质段在加热过程中难以确保气溶胶的释放量在抽吸的前中后段保持一致，因此，在抽吸过程中，难以保证抽吸的一致性，抽吸体验感较差。
而本申请实施例的气溶胶生成基质段10是设置了多个并行排列，且具有第一密度区域111和第二密度区域112的混合密度基质条11，第一密度区域111和第二密度区域112沿混合密度基质条11的横截面排布，且第一密度区域111的密度小于第二密度区域112的密度，也就是说，混合密度基质条11既有密度相对较低的区域，也有密度相对较高的区域，因此，具有多个混合密度基质条11的气溶胶生成基质段10也同时具有密度相对较低的区域以及密度相对较高的区域。在加热初始阶段，密度相对较低的第一密度区域111的红外透射效率高于密度相对较高的第二密度区域112，且密度相对较低的第一密度区域111的热容更小，与第二密度区域112相比，第一密度区域111可以在抽吸前段产生较为充足的气溶胶，此种优势对于红外加热的发热组件更为明显，而在抽吸的中后段，虽然第一密度区域111产生的气溶胶会出现衰减，但第二密度区域112可以产生较为充足的气溶胶，因此，通过第一密度区域111和第二密度区域112的配合，可以使气溶胶的释放量在抽吸的前中后段大致保持一致，从而可以提高抽吸的一致性，进而可以提高抽吸体验感。
一实施例中，第一密度区域111和第二密度区域112分别具有香味物质，位于第一密度区域111的香味物质的沸点可以大于位于第二密度区域112的香味物质的沸点。也就是说，与位于第一密度区域111的香味物质相比，位于第二密度区域112的香味物质更易挥发。
具体地，由于在加热过程中，第一密度区域111释放气溶胶的速度大于第二密度区域112释放气溶胶的速度，因此，可以将香味物质按照其沸点高低分别分布在第一密度区域111与第二密度区域112中，从而可以提高抽吸过程中香气特征的一致性，以进一步提升抽吸体验。
在另一些实施例中，位于第一密度区域111的香味物质的沸点也可以与位于第二密度区域112的香味物质的沸点相同。
一实施例中，各混合密度基质条11的第一密度区域111朝向气溶胶生成基质段10的中心，也就是说，各混合密度基质条11的第二密度区域112朝向气溶胶生成基质段10的外侧。由于中心加热方式是对气溶胶生成基质段10从内到外进行烘烤加热，因此，各混合密度基质条11的第一密度区域111朝向气溶胶生成基质段10的中心，可以使加热组件的热量先传递至各混合密度基质条11的第一密度区域111，再传递至同一混合密度基质条11的第二密度区域112，以确保在加热前段，第一密度区域111能够充分释放气溶胶，从而可以提升加热过程中气溶胶释放的一致性。
在另一实施例中，也可以是各混合密度基质条11的第二密度区域112朝向气溶胶生成基质段10的中心，也就是说，各混合密度基质条11的第一密度区域111朝向气溶胶生成基质段10的外侧。由于周圈加热方式是对气溶胶生成基质段10进行从外到内的烘烤加热，因此，各混合密度基质条11的第二密度区域112朝向气溶胶生成基质段10的中心，也可以使加热组件的热量先传递至各混合密度基质条11的第一密度区域111，再传递至同一混合密度基质条11的第二密度区域112，以确保在加热前段，第一密度区域111能够充分释放气溶胶，从而可以提升加热过程中气溶胶释放的一致性。
一实施例中，请参阅图5和图6，气溶胶生成基质段10还可以设置等密度基质条12，等密度基质条12是指整个等密度基质条12的密度大致均匀，不存在密度具有明显差异的区域。等密度基质条12在气溶胶生成基质段10沿第一方向的相对两端之间延伸。
也就是说，等密度基质条12可以与混合密度基质条11配合使用，以满足不同的加热需求。
等密度基质条12的数量可以是一个，也可以是多个。
示例性地，等密度基质条12的数量为多个，且各等密度基质条12的密度大于第一密度区域111的密度，需要说明的是，各等密度基质条12的密度可以与第二密度区域112的密度相同，也可以不同。
请参阅图5，对于中心加热方式，所有等密度基质条12可以环绕在所有混合密度基质条11的周侧。
所有等密度基质条12可以在所有混合密度基质条11的周侧环绕成一圈或多圈，比如，图5所示的所有等密度基质条12在所有混合密度基质条11的周侧环绕成两圈。
混合密度基质条11和等密度基质条12的数量比可以根据需要进行设计，比如，混合密度基质条11和等密度基质条12的数量比可以为1：10～5：1(包括端点值)，比如1：10、1：5、2：3、2：1、3：1、5：1等。
由于中心加热方式是对气溶胶生成基质段10从内到外进行烘烤加热，因此，所有等密度基质条12环绕在所有混合密度基质条11的周侧，可以使混合密度基质条11集中在靠近加热组件的区域，以确保在加热前段，第一密度区域111能够充分释放气溶胶，在中后段，第二密度区域112和等密度基质条12也可以充分释放气溶胶，从而可以提升加热过程中气溶胶释放的一致性。
请参阅图6，对于周圈加热方式，所有混合密度基质条11可以环绕在所有等密度基质条12的周侧。
所有混合密度基质条11可以在所有等密度基质条12的周侧环绕成一圈或多圈，比如，图6所示的所有混合密度基质条11在所有等密度基质条12的周侧环绕成一圈。
混合密度基质条11和等密度基质条12的数量比可以根据需要进行设计，比如，混合密度基质条11和等密度基质条12的数量比可以为1：3～3：1(包括端点值)，比如1：3、2：3、2：1、3：1等。
由于周圈加热方式是对气溶胶生成基质段10进行从外到内的烘烤加热，因此，所有混合密度基质条11环绕在所有等密度基质条12的周侧，可以使混合密度基质条11集中在靠近加热组件的区域，以确保在加热前段，第一密度区域111能够充分释放气溶胶，在中后段，第二密度区域112和等密度基质条12也可以充分释放气溶胶，从而可以提升加热过程中气溶胶释放的一致性。
在另一些实施例中，无论是所有等密度基质条12环绕在所有混合密度基质条11的周侧，还是所有混合密度基质条11环绕在所有等密度基质条12的周侧，
各等密度基质条12的密度也可以小于第一密度区域111的密度。一实施例中，请参阅图10至图12，降温段21可以设置气流通道21a，气溶胶生成制品还包括透气膜30，透气膜30可以设置在降温段21上，且气流通道21a至少靠近气溶胶生成基质段10的一端覆盖有透气膜30。也就是说，可以只在气流通道21a靠近气溶胶生成基质段10的一端覆盖透气膜30，也可以在气流通道21a的相对两端分别覆盖透气膜30。
透气膜30是可供气流通过的膜，也就是说，气溶胶生成基质段10产生的气溶胶可以穿过透气膜30进入气流通道21a中，并在气流通道21a中进行降温。
示例性地，透气膜30可以是具有较好的透气性能的卷烟纸、无纺布、高分子聚合物等。
示例性地，透气膜30的透气度可以大于等于500CU(CU是cm3/(min*cm2*kpa)的简称)。
气流通道21a靠近气溶胶生成基质段10的一端所覆盖的透气膜30可以对混合密度基质条11(如果有等密度基质条12，则也包括等密度基质条12)进行阻挡，以防止基质条在意外情况下进入气流通道21a中(比如中心加热的发热体将基质条顶入气流通道21a)，由此，既可以防止基质条进入气流通道21a后，导致能被加热的基质条的数量减少，影响加热效果，也可以防止基质条堵塞气流通道21a，影响吸阻。需要说明的是，降温段21并不仅限于管体和透气膜30的结构形式，在另一些实施例中，降温段21也可以采用其它的结构形式，只要能够起到降温作用即可。
另外，在气流通道21a的相对两端分别覆盖透气膜30的目的在于，在组装气溶胶生成制品的过程中可以不用区分降温段21的组装方向，以提高组装的便利性。
在另一些实施例中，透气膜30也可以不设置在降温段21上，比如，透气膜30可以设置在气溶胶生成基质段10上，且气溶胶生成基质段10至少靠近气流通道21a的一端覆盖有透气膜30，也就是说，可以只在气溶胶生成基质段10靠近气流通道21a的一端覆盖透气膜30，也可以在气溶胶生成基质段10靠近气流通道21a的一端以及气溶胶生成基质段10背离气流通道21a的一端分别覆盖透气膜30，相当于气溶胶生成基质段10沿第一方向的相对两端分别覆盖透气膜30。气溶胶生成基质段10沿第一方向的相对两端分别覆盖透气膜30，也可以在组装气溶胶生成制品的过程中不用区分气溶胶生成基质段10的组装方向，以提高组装的便利性。
在另一些实施例中，降温段21也可以采用其它的结构形式，只要能够起到降温作用即可。
一实施例中，请参阅图12，过滤段22可以设置抽吸通道22a，以起到调节吸阻的作用。
一实施例中，请参阅图10至图12，功能段20还可以设置增香段23，增香段23设置在降温段21与过滤段22之间，以起到烟气香味补偿和提升抽吸口感的作用。
增香段23的结构形式不限，示例性地，增香段23可以设置经过增香处理的纤维棉231，或者，增香段23也可以设置纤维棉231和爆珠232，纤维棉231可以是经过增香处理的纤维棉231，也可以是没有经过增香处理的纤维棉231，爆珠232设置在纤维棉231内。
在另一些实施例中，功能段20也可以不设置增香段23。
在一些实施例中，气溶胶生成制品可以没有功能段20，即气溶胶生成基质段10单独就可以构成气溶胶生成制品，以用于一些特殊的气溶胶生成装置中，例如，气溶胶生成装置包括吸嘴和冷却部件，吸嘴和冷却部件可以重复利用或者一次性使用，只用将气溶胶生成基质段10插入或移出加热空间内即可。基质条可以为上述所有实施例中的基质条以及组装结构，在此不再一一赘述。
另外，对于没有功能段20的气溶胶生成基质段10，根据设计需要，也可以在气溶胶生成基质段10的至少一端设置透气膜30。
以上实施例中，气溶胶生成基质段10可以是圆柱形、片状、方形等，可以根据加热组件和气溶胶生成装置的特点进行适配。

数据分析：气溶胶生成基质段在加热过程中产生的逐口烟雾量(即气溶胶)的平均值为3.56mg/puff，逐口烟雾量的RSD(相对标准偏差)＝38.3％，加热过程中，抽吸前段产的烟雾量、烟气中的气溶胶生成剂、尼古丁等有效物质的逐口释放表现较为充足，但在抽吸中后段出现明显衰减。主要原因是因为气溶胶生成基质段的密度较低，有效负载较低且有限，从而导致抽吸前后段的一致性比较差。
对比测试例2
测试样品：呈等径圆柱状的气溶胶生成基质段，气溶胶生成基质段由多个等密度基质条构成，等密度基质条的横截面形状为圆形，直径为1mm，密度为1100mg/cm3。
测试器具：与本申请测试例相同。
测试条件：与本申请测试例相同。
测试结果：见表三(单位均为mg，PG为丙三醇，VG为丙二醇)。
表三
数据分析：气溶胶生成基质段在加热过程中产生的逐口烟雾量(即气溶胶)的平均值为4.07mg/puff，逐口烟雾量的RSD(相对标准偏差)＝29.4％，加热过程中，抽吸前段产的烟雾量、烟气中的气溶胶生成剂、尼古丁等有效物质的逐口释放表现较少，但在抽吸中后段出现明显提升。主要原因是因为气溶胶生成基质段的密度较高，有效负载较高，在抽吸前段，气溶胶生成基质段需要吸收足够的热量才能产生稳定的气溶胶，因此，在抽吸前段的抽吸体验比较差。
对比测试例3
均质化的薄片状气溶胶生成基质，密度为799mg/cm3。
测试器具：与本申请测试例相同。
测试条件：与本申请测试例相同。
测试结果：见表四(单位均为mg，PG为丙三醇，VG为丙二醇)。
表四

数据分析：气溶胶生成基质在加热过程中产生的逐口烟雾量(即气溶胶)的平均值为3.54mg/puff，逐口烟雾量的RSD(相对标准偏差)＝23.8％，在相同测试条件下，对比例3的气溶胶生成基质在抽吸前后段产生的气溶胶比本申请测试例的气溶胶生成基质段少29.6％，主要原因是薄片状气溶胶生成基质与本申请测试例的气溶胶生成基质段在形态上存在明显差异，空隙形状和分布相差较大，且薄片状气溶胶生成基质的密度较低，有效负载较低，从而导致抽吸过程中产生的气溶胶有限。
