具体实施方式
为使本领域的技术人员更好地理解本公开实施例的技术方案，下面结合附图对本公开实施例提供的一种终端进行详细描述。

本公开实施例可借助本公开的理想示意图而参考平面图和/或截面图进行描述。因此，可根据制造技术和/或容限来修改示例图示。
在不冲突的情况下，本公开各实施例及实施例中的各特征可相互组合。

在一些相关技术中，终端存在折叠和打开等多种状态，当终端在折叠状态时，天线可能被折叠后重合部分遮挡，造成天线在终端的不同状态下，性能差异较大。为了减少对用户体验的影响，在一些相关技术中，优先保证一种状态下天线的性能(如保证打开状态下天线的性能)，当使用终端的用户需要使用该天线的功能时，用户需要将终端打开以保证天线性能，并最终保证终端功能的正常使用。这样虽然保证了天线的性能，但用户在使用相应功能时，需要将终端保持在相应的状态，对用户体验造成了影响。
在另一些相关技术中，为了解决天线在终端的不同状态下，性能差异较大的问题，牺牲终端的大小或造型，将终端设计为非对称折叠，即当终端在折叠状态下时，折叠部分并不是完全重合，以保证终端在折叠状态下依然存在未被遮挡的区域(即不重合的区域)，将天线设置在未被遮挡的区域，可以保证天线性能在终端在折叠状态下与终端与打开状态下差异不大。用户在终端任何状态下都可以使用相应功能，减少对用户体验的影响。
但随着终端功能的丰富以及5G时代的到来，终端使用的天线数量越来越多，要求也越来越高，同时用户对终端的大小和造型的要求也越来越高，非对称折叠的终端已经无法满足用户的期待。
有鉴于此，参照图1至图3，本公开提供一种终端，其可以包括：第一折叠部11和第二折叠部12；终端至少具有打开和折叠两种状态，当终端折叠时，第一折叠部11的第一重合区与第二折叠部12的第二重合区相对设置；当终端打开时，第一重合区和第二重合区不相对；终端还包括至少一组天线结构；每组天线结构包括：设于第一重合区和第二重合区的一者中的第一天线8，以及设于第一重合区和第二重合区的另一者中的辐射体9；当终端折叠时，第一天线8与辐射体9 至少部分相对设置且能产生耦合作用。
在本文中，可以理解的是，两个部件相对设置是指两个部件在平面上的投影实质上重叠。例如，第一重合区与第二重合区相对设置可以指在终端折叠时，第一重合区在第一折叠部11上的正投影与第二重合区在第一折叠部11上的正投影重叠。类似地，两个部件至少部分相对设置是指两个部件在平面上的正投影至少部分重叠。
本公开的终端包括可以围绕转轴1单独旋转的第一折叠部11和第二折叠部12，即第一折叠部11可以在第二折叠部12不旋转的情况下沿转轴1单独旋转，第二折叠部12同样可以在第一折叠部11不旋转的情况下沿转轴1单独旋转。第一折叠部11和第二折叠部12之间的“夹角”随着第一折叠部11和第二折叠部12的旋转改变。例如，第一折叠部11和第二折叠部12之间的“夹角”可以从0度变化至180度。
本公开的终端至少具有折叠和打开两种状态，当终端在折叠状态下，终端的第一折叠部11和第二折叠部12相对设置，例如可以是终端的第一折叠部11的一面与第二折叠部12的一面至少部分“接触”，即第一折叠部11和第二折叠部12之间的“夹角”为0度。第一折叠部11中与第二折叠部12“接触”的区域为第一重合区，第二折叠部12中对应的区域为第二重合区。
当终端在打开状态下，终端的第一折叠部11和第二折叠部12的“夹角”变化为最大值，例如可以是180度，也就是说，第一折叠部11和第二折叠部12在折叠状态下“接触”的一面在打开状态下在同一个平面。当然，当终端在打开状态下，位于第一折叠部11的第一重合区和位于第二折叠部12的第二重合区也随着第一折叠部11和第二折叠部12变化，从相对设置变化为不相对。
本公开的终端还包括至少一组天线结构，每一组天线结构包括第一天线8、辐射体9。第一天线8与辐射体9位于不同的重合区，即当第一天线8位于第一重合区时，辐射体9位于第二重合区；当第一天线8位于第二重合区时，辐射体9位于第一重合区。且第一天线8和辐射体9是位于不同重合区相对的位置上，也就是说，当终端在 折叠状态下，即当第一重合区和第二重合区相对设置时，位于不同重合区的第一天线8和辐射体9也至少部分相对设置。当终端在打开状态下，由于第一天线8和辐射体9位于不同的重合区，因此并不相对。
当然，一个终端可以具有多组天线结构(极端情况下，每一条天线都有对应的天线结构)，不同组天线结构的第一天线8可以位于不同的重合区，如某一组天线结构的第一天线8位于第一重合区，对应的辐射体9位于第二重合区。另一组天线结构的第一天线8位于第二重合区，对应的辐射体9位于第一重合区。
当终端在折叠状态下，位于第一重合区或第二重合区的第一天线8可能被折叠后与其相对设置的另一个重合区遮挡，但由于在另一个重合区与其相对设置的是辐射体9，辐射体9可以与第一天线8产生耦合作用，辐射体9也“成为”第一天线8的一部分，第一天线8的带宽得到了拓宽，第一天线8的性能也相应得到了改善。换句话说，当终端在折叠状态下，即使第一天线8被遮挡，也可通过与辐射体9产生耦合作用，并激励出谐振，改善第一天线8的性能，使其满足终端功能的需求。
由于天线和辐射体一般都“埋于”终端的内部，即第一天线8和辐射体并不会位于第一重合区和第二重合区“接触”的面上，也就是说，第一天线8和辐射体并不是电连接的，而是通过产生耦合作用来改善第一天线8的性能。当然，终端中可能存在很多与辐射体9类似的器件，其也可能与第一天线8产生耦合作用，但这些耦合是极弱的，而辐射体9与第一天线8的耦合是具有一定强度的，其可以满足改善第一天线8的性能的要求。
当终端在打开状态下，第一折叠部11和第二折叠部12并没有相对设置，因此位于第一重合区或第二重合区的第一天线8并不会被另一个重合区遮挡，性能并不会受到影响，可以正常使用。同时，第一天线8和辐射体9并不相对，因此辐射体9也并不会和第一天线8产生耦合，对第一天线8造成影响。
其中，本公开的终端可以是一切可折叠且具有天线的设备，如手机、平板电脑等。第一折叠部11和第二折叠部12可以是终端上任 何布有天线的部分，如折叠屏手机的折叠屏幕所在的部分。第一折叠部11可以全部都是第一重合区，第二折叠部12也可以全部都是第二重合区，当第一折叠部11全部都是第一重合区，第二折叠部12也全部都是第二重合区时，可以认为终端是以转轴1为堆成中心完全对称折叠的。
第一天线8的种类也并不限定，其可以为终端使用的天线中任意一种，如2/3/4G主天线、2/3/4G分集天线、LTE(长期演进)4*4mimo(Multi-input Multi-output，多入多出)天线、5G nR(接入网)主天线、nR分集天线、nR 4*4mimo天线、GPS(全球定位系统)天线、WIFI天线、WIFI mimo天线等。
本公开的终端，在终端折叠状态下第一天线8相对位置设置辐射体9，通过辐射体9和第一天线8产生耦合作用，拓宽终端折叠状态下第一天线8的带宽，提升终端折叠状态下第一天线8的性能，使其在被遮挡的情况下，依然可以满足用户使用终端对应功能的要求，提升终端折叠状态下用户体验。同时，在终端打开状态下，辐射体9和第一天线8由于处于不同的重合区并不会产生耦合作用，因此并不会对用户在终端打开状态下的用户体验造成影响。
在一些实施方式中，辐射体9为金属。
本公开的辐射体9可以为金属辐射体，金属辐射体可以更好的与天线产生耦合。当辐射体9为金属辐射体时，辐射体9与第一天线8之间更容易发生耦合作用，也更加方便改善第一天线8的性能。
本公开的金属辐射体9可以是使用金属边框实现的金属辐射体，也可以是单独内嵌的金属条，当然其也可以嵌入FPC(Flexible Printed Circuit，柔性电路板)，作为FPC的一部分；也可以通过PDS(印刷成型)、LDS(Laser Direct Structuring，激光直接成型技术)嵌入塑料结构件上。
在一些实施方式中，辐射体9与第一天线8使用不同的工艺制作。
即金属辐射体9与第一天线8通过不同的工艺实现，如第一天线8使用金属边框实现，而金属辐射体9则通过LDS(Laser Direct  Structuring，激光直接成型技术)工艺实现。当然，金属辐射体9与第一天线8也可以使用相同的工艺实现，如都使用金属边框实现。
第一天线8和金属辐射体9的实现工艺并不要求相同，使得金属辐射体9的实现更加容易。不同的终端可以根据不同的需求选择不同的工艺实现金属辐射体9。
在一些实施方式中，辐射体9浮接或单点接地。
辐射体9是独立的(或者说独立于终端其他器件)，其浮接或单点接地(保证辐射体9内并不是强加的接地信号，也并不是完全没有信号)，且没有射频信号馈入，即当终端在打开状态下，辐射体9并不工作，减少对第一天线8的影响。当终端在折叠状态下，浮接或单点接地的辐射体9可以与第一天线8产生耦合作用，辐射体9也“成为”第一天线8的一部分，使得第一天线8的带宽得到了拓宽，第一天线8的性能也相应得到了改善。
辐射体9浮接或者单点节点可以保证其并不是完全没有信号，因此在终端折叠状态下可以和第一天线8产生耦合作用，而在终端打开状态下却不工作，一方面避免了浪费，另一方面也减少了对第一天线8的影响。
在一些实施方式中，辐射体9设置在终端的不同位置(如顶部、底部、侧边等)。因为辐射体9是独立结构，其可根据需要位于终端的不同位置，如当第一天线8位于终端的顶部，则辐射体9也可位于终端的顶部。
辐射体9独立的特点，使得其可以根据需要位于终端的不同位置，并不受到终端其他部件的影响，也使得天线结构更加易于实现(辐射体9只需根据第一天线8位置设置即可)。
在一些实施方式中，至少部分组天线结构中的第一天线8和辐射体9形状相同，且当终端折叠时完全相对设置。
本公开的终端的天线结构中至少有部分组天线结构中，第一天线8与辐射体9形状相同(即大小、长度、厚度相同)，且当终端折叠后，位于不同重合区的第一天线8和辐射体9完全相对设置。即若辐射体9通过折叠方向上的平移，可以和第一天线8完全重合。
当然，第一天线8和辐射体9形状可以不同，即大小、长度、厚度中一个或多个不同，如第一天线8和辐射体9长度不同。
不同的终端可以根据不同的需求灵活设置不同的第一天线8和辐射体9的形状，如与第一天线8完全相对的位置设置有其他器件，则可以将辐射体9设置在于第一天线8部分相对的位置即可，若设置在该位置，辐射体9与第一天线8产生的耦合作用不够，则可以通过调谐开关或者可变电容等方式进行调节。
在一些实施方式中，至少部分组天线结构还包括调节器10；调节器10用于调节辐射体9的电流与阻抗。
在一些实施方式中，调节器10包括调谐开关，调谐开关用于调节辐射体9的电流与阻抗。
本公开的终端的天线结构中，至少部分组天线结构具有调谐开关，调谐开关与辐射体9位于同一个重合区，即当辐射体9位于第一重合区，调谐开关也位于第一重合区；当辐射体9位于第二重合区，调谐开关也位于第二重合区，其可以根据需要设置在辐射体9的不同相对位置(如辐射体9的中间)。
当然，一个天线结构中可以包括多个调谐开关，不同的调谐开关可以位于辐射体9不同的相对位置(如辐射体9的两端)。
辐射体9通过调谐开关和终端的地连接，通过调谐开关可以改变辐射体9上的电流与阻抗，进而改变辐射体9与第一天线8产生的耦合作用的强度，以更好的改善第一天线8在终端不同状态下的性能。
即当终端从打开状态慢慢变为折叠状态，在这个过程中，辐射体9与第一天线8慢慢接近，同时，第一天线8也慢慢被遮挡。由于辐射体9并不是通过和第一天线8电连接来改变第一天线8的性能，而是通过与第一天线8产生耦合作用改变第一天线8的性能，因此，在辐射体9与第一天线8慢慢接近的过程中，辐射体9可能已经和第一天线8产生耦合作用，此时就需要调谐开关对辐射体9的电流与阻抗进行调节以对辐射体9和第一天线8的产生耦合作用的强度进行调节，以实现对第一天线8性能的调节，使其可以在终端从打开状态变为折叠状态的过程中(即不断被遮挡的过程中)，性能不会发生大的 改变。
例如，辐射体9、调谐开关和第一天线8调谐形成天线系统，共同使用闭环调谐，对第一天线8的性能根据不同的需求进行动态的调整。
当然，并不仅限于终端状态发生变化的过程，当终端的状态没有发生变化(终端始终处于折叠状态)，但天线的性能发生变化(如受环境影响，性能下降)，或者用户对天线性能需求发生变化(如用户需要更好的天线性能)，也可以通过调谐开关对辐射体9的电流与阻抗进行调节，实现对辐射体9和第一天线8的产生耦合作用的强度进行调节，并最终实现对第一天线8性能的调节。
通过调谐开关，可以最终对第一天线8的性能进行调节，使其更加适应终端的不同状态以及不同的环境情况与不同的性能需求，进一步提升了用户体验。
在一些实施方式中，调节器10包括可变电容；可变电容用于调节辐射体9的电流与阻抗。
本公开的终端的天线结构中，至少部分组天线结构具有可变电容，可变电容与辐射体9位于同一个重合区，即当辐射体9位于第一重合区，可变电容也位于第一重合区；当辐射体9位于第二重合区，可变电容也位于第二重合区，其可以根据需要设置在辐射体9的不同相对位置(如辐射体9的中间)。
当然，一个天线结构中可以包括多个可变电容，不同的可变电容可以位于辐射体9不同的相对位置(如辐射体9的两端)。
辐射体9通过可变电容和终端的地连接，通过可变电容可以改变辐射体9上的电流与阻抗，进而改变辐射体9与第一天线8产生的耦合作用的强度，以更好的改善第一天线8在终端不同状态下的性能。
即当终端从打开状态慢慢变为折叠状态，在这个过程中，辐射体9与第一天线8慢慢接近，同时，第一天线8也慢慢被遮挡。由于辐射体9并不是通过和第一天线8电连接来改变第一天线8的性能，而是通过与第一天线8产生耦合作用改变第一天线8的性能，因此，在辐射体9与第一天线8慢慢接近的过程中，辐射体9可能已经和第 一天线8产生耦合作用，此时就需要可变电容对辐射体9的电流与阻抗进行调节以对辐射体9和第一天线8的产生耦合作用的强度进行调节，以实现对第一天线8性能的调节，使其可以在终端从打开状态变为折叠状态的过程中(即不断被遮挡的过程中)，性能不会发生大的改变。
例如，辐射体9、可变电容和第一天线8调谐形成天线系统，共同使用闭环调谐，对第一天线8的性能根据不同的需求进行动态的调整。
当然，并不仅限于终端状态发生变化的过程，当终端的状态没有发生变化(终端始终处于折叠状态)，但天线的性能发生变化(如受环境影响，性能下降)，或者用户对天线性能需求发生变化(如用户需要更好的天线性能)，也可以通过可变电容对辐射体9的电流与阻抗进行调节，实现对辐射体9和第一天线8的产生耦合作用的强度进行调节，并最终实现对第一天线8性能的调节。
可变电容在天线结构中起到的作用与调谐开关类似，即其可以对辐射体9的电流与阻抗进行调节，以调节辐射体9与第一天线8产生耦合作用的强度，最终实现对第一天线8性能的调节，使其可以满足终端的不同状态以及不同的环境情况与不同的性能需求，提升用户体验。不同终端可以根据不同的情况，选择使用调谐开关或者可变电容，一个天线结构既使用可变电容，也使用调谐开关当然也是可以的。
在一些实施方式中，至少部分组天线结构还包括：与辐射体9位于同一个重合区中的第二天线；当终端打开时，第二天线与辐射体9能产生耦合作用。
本公开的终端的至少部分天线结构还包括第二天线，第二天线与辐射体9位于同一个重合区，例如，第二天线可以位于辐射体9附近。
当终端在打开状态下，辐射体9与第二天线产生耦合作用(例如，辐射体9与第二天线主辐射臂产生耦合作用)，对第二天线的性能进行改善。当终端在折叠状态下，金属辐射体9与第一天线8产生 耦合作用，对第一天线8的性能进行改善。
在一些实施方式中，天线结构还包括与辐射体9以及第二天线位于同一个重合区的调谐开关或可变电容，例如调节器10。
当终端在打开状态下，辐射体9与第二天线产生耦合作用(例如，辐射体9与第二天线主辐射臂产生耦合作用)，通过调谐开关或可变电容对辐射体9的电流与阻抗进行调节，实现对辐射体9和第二天线的产生耦合作用的强度进行调节，最终实现对第二天线的性能进行改善。当终端在折叠状态下，金属辐射体9与第一天线8产生耦合作用，通过调谐开关或可变电容对辐射体9的电流与阻抗进行调节，实现对辐射体9和第一天线8的产生耦合作用的强度进行调节，最终实现对第一天线8的性能进行改善。
当然，辐射体9、可变电容或调谐开关也可以和第一天线8以及第二天线调谐形成天线系统，共同使用闭环调谐，对第一天线8、第二天线的性能根据不同的需求进行动态的调整。
一个天线结构包括两条天线，使得一个辐射体9可以对第一天线8和第二天线两条天线的性能进行调节，这大大减少了终端需要设置的辐射体9的数量，为终端设置其他器件留出了空间。同时，辐射体9在终端打开状态下，对第二天线进行调节，也避免了辐射体9在终端打开时不能工作造成的浪费，节约了成本。
在一些实施方式中，当终端折叠时，第一折叠部11和第二折叠部12完全相对设置。
即终端是完全对称终端，第一重合区占满了第一折叠部11，第二重合区占满了第二折叠部12。完全对称终端可以使得终端折叠后更加便携，同时，由于完全对称终端不存在未被遮挡区域，并不能通过将天线设置在未被遮挡区域来减少终端折叠对天线性能的影响。而本公开在终端折叠状态下第一天线8相对位置设置辐射体9，通过辐射体9和第一天线8产生耦合作用，拓宽终端折叠状态下第一天线8的带宽，提升终端折叠状态下第一天线8的性能，使其在被遮挡的情况下，依然可以满足用户使用终端对应功能的要求，也就是说，本公开的终端为完全对称终端，第一天线8的性能仍不会受到影响。
在一些实施方式中，终端包括屏幕，第一折叠部11和第二折叠部12属于屏幕。
在一些实施方式中，第一折叠部11具有显示侧，第二折叠部12具有显示侧，当终端折叠时，第一折叠部11的显示侧和第二折叠部12的显示侧相对设置。
本公开的终端可以例如为折叠屏手机，第一折叠部11和第二折叠部12为终端可折叠的屏幕，其都具有显示侧，用于显示画面、接收用户交互等，当终端在折叠状态下，第一折叠部11的显示侧和第二折叠部12的显示侧相对设置，可以对屏幕进行保护。
以下更详细地描述本公开的示例性实施方式，可以理解的是，在不冲突的情况下，各示例性实施方式中的特征可以与上述实施方式中的特征任意组合。
第一示例性实施方式
参照图1，本公开的终端，可以为金属边框的折叠手机，其可以包括：转轴1以及折叠对称轴2，终端为完全对称终端，即第一折叠部11也是第一重合区，第二折叠部12也是第二重合区。终端电池3以及终端的子板4(电池和主板显然埋于终端内部，因此用虚线表示)都位于第一折叠部11；终端的主板7以及USB接口5和speaker接口(喇叭接口)6都位于第二折叠部12。
第一折叠部11和第二折叠部12可以沿转轴1或者说折叠对称轴2单独旋转并最终折叠在一起，相当于图1以转轴为中心对折，重合的部件即为第一折叠部11和第二折叠部12相对设置的部件。
其中，天线结构包括第一天线8、金属辐射体9。第一天线8为LTE主天线，其设置在第一折叠部11底部区域；LTE主天线馈点81和LTE主天线地点82位于LTE主天线8上，浮接的金属辐射体9，设置在第二折叠部12底部区域。当终端通过转轴1按折叠对称轴2折叠时，LTE主天线8和浮接的金属辐射体9完全“重合”(即完全相对设置)，浮接的金属辐射体9和LTE主天线8发生耦合作用，金属辐射体9会产生耦合电流，并激励出一个低频谐振，从而拓宽了LTE主天线8的带宽，改善折叠状态下LTE主天线8的性能。
第二示例性实施方式
参照图2，本公开的终端，可以为金属边框的折叠手机，其可以包括：转轴1以及折叠对称轴2，终端为完全对称终端，即第一折叠部11也是第一重合区，第二折叠部12也是第二重合区。终端电池3以及两块终端的子板4(电池和主板显然埋于终端内部，因此用虚线表示)都位于第一折叠部11；终端的主板7以及USB接口5和speaker接口(喇叭接口)6都位于第二折叠部12。
第一折叠部11和第二折叠部12可以沿转轴1或者说折叠对称轴2单独旋转并最终折叠在一起，相当于图2以转轴为中心对折，重合的部件即为第一折叠部11和第二折叠部12相对设置的部件。
其中，天线结构包括第一天线8、金属辐射体9以及调节器10(例如调谐开关或可变电容)。第一天线8为N78/N79天线，其设置在第一折叠部11；N78/N79天线馈点81和N78/N79天线地点82位于N78/N79天线8上，浮接的金属辐射体9和调谐开关，设置在第二折叠部12。当终端通过转轴1按折叠对称轴2折叠时，N78/N79天线8和浮接的金属辐射体9部分“重合”(即部分相对设置)，浮接的金属辐射体9和N78/N79天线8发生耦合作用，金属辐射体9会产生耦合电流，并激励出一个高频谐振。
但由于悬浮金属辐射体9的长度要小于N78/N79天线8的长度(即N78/N79天线8和浮接的金属辐射体9不是完全相对设置)，耦合产生的高频谐振可能无法满足N78/N79天线8需求，因此通过调节器10(例如调谐开关或可变电容)调节金属辐射体9的电流和阻抗，使得金属辐射体9和N78/N79天线8发生耦合作用，产生的谐振可为N78/N79天线8所用，以改善了N78/N79天线8在终端折叠状态下的性能。
第三示例性实施方式
参照图3，本公开的终端，可以为金属边框的折叠手机，其可以包括：转轴1以及折叠对称轴2，终端为完全对称终端，即第一折叠部11也是第一重合区，第二折叠部12也是第二重合区。终端电池3以及两块终端的子板4(电池和主板显然埋于终端内部，因此用虚线 表示)都位于第一折叠部11；终端的主板7以及USB接口5和speaker接口(喇叭接口)6都位于第二折叠部12。
第一折叠部11和第二折叠部12可以沿转轴1或者说折叠对称轴2单独旋转并最终折叠在一起，相当于图1以转轴为中心对折，重合的部件即为第一折叠部11和第二折叠部12相对设置的部件。
其中，天线结构包括第一天线8、金属辐射体9。第一天线8为GPS/WIFI天线，其设置在第一折叠部11；GPS/WIFI天线馈点81位于GPS/WIFI天线8上，浮接的金属辐射体9，设置在第二折叠部12。当终端通过转轴1按折叠对称轴2折叠时，GPS/WIFI天线8和浮接的金属辐射体9完全“重合”(即完全相对设置)，浮接的金属辐射体9和GPS/WIFI天线8发生耦合作用，金属辐射体9会产生耦合电流，并激励出一个2.35GHz谐振，从而拓宽了GPS/WIFI天线8的WIFI2.4GHz的带宽，改善折叠状态下GPS/WIFI天线8的性能，提高了GPS/WIFI天线8的效率。
本公开的终端，在终端折叠状态下第一天线相对位置设置辐射体，通过辐射体和第一天线产生耦合作用，拓宽终端折叠状态下第一天线的带宽，提升终端折叠状态下第一天线的性能，使其在被遮挡的情况下，依然可以满足用户使用终端对应功能的要求，提升终端折叠状态下用户体验。同时，在终端打开状态下，辐射体和第一天线由于处于不同的重合区并不会产生耦合作用，因此并不会对用户在终端打开状态下的用户体验造成影响。
本公开已经公开了示例实施方式，并且虽然采用了具体术语，但它们仅用于并仅应当被解释为一般说明性含义，并且不用于限制的目的。在一些实例中，对本领域技术人员显而易见的是，除非另外明确指出，否则可单独使用与特定实施例相结合描述的特征、特性和/或元素，或可与其他实施例相结合描述的特征、特性和/或元件组合使用。因此，本领域技术人员将理解，在不脱离由所附的权利要求阐明的本公开的范围的情况下，可进行各种形式和细节上的改变。
