具体实施方式
下面将结合附图对本申请的多个实施例进行阐述。
本申请的第一实施例涉及一种参数调整的方法，应用于设备，例如：基站等。流程如图1所示，包括：
步骤101，获取设备的第一性能指标的指标值。
设备自动获取最近一个预设时间内设备的第一性能指标的指标值，预设时间可以根据实际需要进行设定，例如：预设时间为15分钟。第一性能指标可以是一种类型的性能指标，例如：第一性能指标为小区的上行误块率BLER 本，获取BLER 本的指标值；第一性能指标也可以是多种类型的性能指标，则分别获取多种类型的性能指标的指标值，例如：第一性能指标为资源块利用率即物理资源块(Physical Resource Block，PRB)利用率和控制信道单元利用率即控制信道单元(Control Channel Element，CCE)利用率，分别获取PRB利用率的指标值和CCE利用率的指标值。
步骤102，查找第一性能指标的指标值下，设备的目标运行参数的多个候选值中每个候选值的优劣度；候选值的优劣度是指第一性能指标的指标值下将目标运行参数设定为候选值的优劣程度。
优劣度可以用数值进行表示，也可以用好、不好等多种等级进行表示，本实施例以下多个实施例中以数值表示优劣度，数值越大表示越优，然不以此为限。在设备初始运行时，不同的第一性能指标的指标值下，设备的目标运行参数的多个候选值的优劣度的初始值可以均为0，也可以根据实际经验赋予不同的数值；所以，在不同的第一性能指标的指标值下对应的设备的目标运行参数的 多个候选值的优劣度也可能不同，需要查找第一性能指标的指标值下，设备的目标运行参数的每个候选值的优劣度。在一个例子中，设备为基站，第一性能指标为小区的上行误块率BLER 本，目标运行参数为上行发射功率P0。在一个例子中，设备为基站，第一性能指标为小区的资源块利用率即PRB利用率，目标运行参数为表征小区用户迁移管理的参数。例如：表征小区用户迁移管理的参数为踢用户、无操作、吸用户三种操作，踢用户是执行减小连接本小区的用户的操作，吸用户是执行增加连接本小区的用户的操作。其中，基站可以预先设定通过互操作参数实现踢用户操作或吸用户操作，此时的实现方式为通过向选取的用户发送鼓励用户连接其他小区的指令实现踢用户，通过向选取的用户发送鼓励用户连接本小区的指令实现吸用户；也可以预先设定通过改变小区的发射功率实现踢用户操作或吸用户操作，此时的实现方式为通过减小小区的发射功率实现踢用户，通过增大小区的发射功率实现吸用户。
在实际参数调整的应用中，小区的上行误块率会影响上行发射功率的选择，所以第一性能指标为小区的上行误块率，目标运行参数为上行发射功率符合实际应用的需要；小区的资源块利用率会影响小区用户迁移管理的参数的选择，所以第一性能指标为小区的资源块利用率，目标运行参数为小区用户迁移管理的参数符合实际应用的需要。
在一个例子中，直接根据第一性能指标的指标值，就可以查找到第一性能指标的指标值下，设备的目标运行参数的每个候选值的优劣度，例如：若第一性能指标为一种类型的性能指标，第一性能指标的指标值为a下，设备的目标运行参数的多个候选值的优劣度为1、3、4，第一性能指标的指标值为b下，设备的目标运行参数的多个候选值的优劣度为2、5、3，第一性能指标的指标值为c下，设备的目标运行参数的多个候选值的优劣度为4、5、2…；当获取的第一性能指标值为a时，则直接查找到第一性能指标的指标值为a下，设备的目标运行参数的多个候选值的优劣度为1、3、4。若第一性能指标为两种类型的性能指标M、N，第一性能指标M、N的指标值分别为a、b下，设备的目标运行参数的多个候选值的优劣度为1、3、4，第一性能指标M、N的指标值为b、c下，设备的目标运行参数的多个候选值的优劣度为2、5、3，第一性能指标的指标值为c、d下，设备的目标运行参数的多个候选值的优劣度为4、5、2…；当获取的第一性能指标M、N的指标值为a、b时，则直接查找到第一性能指标M、N的指标值为a、b下，设备的目标运行参数的多个候选值的优劣度为1、3、4。
在一个例子中，查找第一性能指标的指标值下，设备的运行参数的多个候选值的优劣度的流程图如图2所示，包括：
步骤1021，确定第一性能指标的指标值所属的当前指标值区间。
步骤1022，根据指标值区间与目标运行参数的每个候选值的优劣度的对应关系，查找当前指标值区间对应的目标运行参数的每个候选值的优劣度，作为第一性能指标的指标值下，设备的目标运行参数的每个候选值的优劣度。
当设备中预设的是指标值区间与运行参数的每个候选值的优劣度的对应关系时，通过本实施例的方法可以简单且准确的确定出第一性能指标的指标值下，设备的目标运行参数的每个候选值的优劣度。
设备预先设定指标值区间与目标运行参数的每个候选值的优劣度的对应关系。指标值区间可以为连续的范围，如：5％＜BLER 本≤10％，也可以为离散的数值组成的集合，如：{5％，6％，7％，8％}。在一个例子中，第一性能指标为一种类型的性能指标，第一性能指标为BLER 本，目标运行参数为P0，P0的多个候选值为-100dBm、-94dBm、-88dBm、-82dBm、-76dBm。指标值区间与目标运行参数的每个候选值的优劣度的对应关系如下表1所示。
表1
Figure PCTCN2021073546-appb-000001
若BLER 本的指标值为11％，则所属的当前指标值区间为10％＜BLER 本≤15％，再根据上表1中的指标值区间与目标运行参数的每个候选值的优劣度的对应关系，查找到当前指标值区间对应的目标运行参数的多个候选值的优劣度为1、8、4、6、2。
在一个例子中，第一性能指标为一种类型的性能指标，第一性能指标为PRB利用率，目标运行参数为表征小区用户迁移管理的参数，即表征小区用户迁移管理的参数的多个候选值为踢用户、无操作、吸用户三种操作。指标值区间与目标运行参数三种操作的候选值的优劣度的对应关系如下表2所示，其中，指标值区间在表2中以状态的形式体现，但是实际上计算机存储时存储的PRB利用率的区间，如PRB利用率为[0％,30％)，PRB利用率为[30％,60％)，PRB利用率为[60％,80％)，PRB利用率为[80％,100％]，而根据实际经验可以将PRB利 用率为[0％,30％)认为设备处于闲的状态，PRB利用率为[30％,60％)认为设备处于较闲的状态，PRB利用率为[60％,80％)认为设备处于较忙的状态，PRB利用率为[80％,100％]认为设备处于忙的状态。

若PRB利用率的指标值为40％时，则所属的当前指标值区间为[30％,60％)，反映在上述表2中为设备处于较闲的状态，再根据上表2中的指标值区间与目标运行参数的每个候选值的优劣度的对应关系，查找到当前指标值区间对应的目标运行参数的多个候选值的优劣度为1、3、5。
在一个例子中，第一性能指标为两种类型的性能指标，第一性能指标为PRB利用率和CCE利用率，目标运行参数为表征小区用户迁移管理的参数，表征小区用户迁移管理的参数的多个候选值为踢用户、无操作、吸用户三种操作。指标值区间与目标运行参数三种操作的候选值的优劣度的对应关系如下表3所示，其中，指标值区间在表3中以状态的形式体现，但是实际上计算机存储时存储的PRB利用率和CCE利用率的区间，如PRB利用率为[0％,40％)和CCE利用率为[0％,50％)，PRB利用率为[0％,40％)和CCE利用率为[50％,100％)，PRB利用率为[40％,100％)和CCE利用率为[0％,50％)，PRB利用率为[40％,100％)和CCE利用率为[50％,100％)，而根据实际经验可以将PRB利用率为[0％,40％)和CCE利用率为[0％,50％)认为设备处于闲的状态，PRB利用率为[0％,40％)和CCE利用率为[50％,100％)认为设备处于较闲的状态，PRB利用率为[40％,100％)和CCE利用率为[0％,50％)认为设备处于较忙的状态，PRB利用率为[40％,100％)和CCE利用率为[50％,100％)认为设备处于忙的状态。

  踢用户 无操作 吸用户
闲 3 0 2
较闲 1 3 5

若PRB利用率的指标值为30％和CCE利用率为20％时，则所属的当前指标值区间为[0％,40％)和[0％,50％)，反映在上述表3中为设备处于闲的状态，再根据上表3中的指标值区间与目标运行参数的每个候选值的优劣度的对应关系，查找到当前指标值区间对应的目标运行参数的多个候选值的优劣度为3、0、2。
步骤103，根据查找到的每个候选值的优劣度，选取一个候选值，作为调整后的目标运行参数的设定值。
在一个例子中，根据查找到的每个候选值的优劣度，选取一个候选值，包括：直接从查找到的每个候选值的优劣度中选取优劣度最高的候选值，或者，从查找到的每个候选值的优劣度中选取优劣度最高的两个候选值的任意一个候选值，等等。
在一个例子中，根据第一性能指标的指标值下，设备的目标运行参数的每个候选值的优劣度，选取一个候选值的流程图如图3所示，包括：
步骤1031，基于ε贪心算法，确定候选值的选取方式；选取方式为随机选取或者根据优劣度选取。
先生成一个随机数x；其中0≤x≤1；若x小于ε，确定候选值的选取方式为随机选取；若x不小于ε，确定候选值的选取方式为根据优劣度选取；其中，
Figure PCTCN2021073546-appb-000002
参数调整的方法周期性执行，T为当前的执行次数。例如：T＝255，ε＝0.067，若x为0.02，则选取方式为随机选取，若x为0.08，则选取方式为根据优劣度选取。
步骤1032，根据选取方式，从候选值中选取一个候选值。
在一个例子中，若选取方式为根据优劣度选取，从候选值中选取优劣度最高的候选值。例如：当前状态下，设备的目标运行参数的多个候选值的优劣度分别为1、8、4、6、2，则选取优劣度为8的候选值。若选取方式为随机选取，则选取任意一个候选值。
基于ε贪心算法可以准确的确定出候选值的选取方式，再根据不同的选取方式选取一个候选值，这样可以较为准确的选出合适的候选值。
本实施例中，先获取设备的第一性能指标的指标值，查找第一性能指标的指标值下，设备的目标运行参数的各候选值的优劣度，并根据查找到的各候选值的优劣度，选取一个候选值作为调整后的目标运行参数的设定值，由于根据优劣度选取的候选值会更加准确，所以调整后的目标参数的设定值更加准确，从而实现自动调整得到较高准确度的参数的目的。
本申请的第二实施例涉及一种参数调整的方法，第二实施例与第一实施例 大致相同，主要区别之处在于：不断的更新不同状态下设备的目标运行参数的每个候选值的优劣度，流程图如图4所示，包括：
步骤201，获取设备的第一性能指标的指标值。
步骤202，查找第一性能指标的指标值下，设备的目标运行参数的每个候选值的优劣度；候选值的优劣度是指第一性能指标的指标值下将目标运行参数设定为候选值的优劣程度。
步骤203，根据查找到的每个候选值的优劣度，选取一个候选值，作为调整后的目标运行参数的设定值。
步骤201-203与步骤101-103类似，在此不再赘述。
步骤204，更新第一性能指标的指标值下选取的候选值的优劣度。
在一个例子中，可以预先设定优劣度的调整值，将优劣度的调整值和原有的优劣度相加得到新的优劣度，将新的优劣度更新为第一性能指标的指标值下选取的候选值的优劣度。例如：预先设定的优劣度的调整值为2，原有的优劣度为3，则新的优劣度为5，则将新的优劣度5更新为第一性能指标的指标值下选取的候选值的优劣度。
在一个例子中，也可以预先设定新的优劣度，直接将新的优劣度更新为第一性能指标的指标值下选取的候选值的优劣度。例如：预先设定新的优劣度为5，则将新的优劣度5更新为第一性能指标的指标值下选取的候选值的优劣度。
本实施例中，通过不断的更新不同第一性能指标的指标值下设备的目标运行参数的候选值的优劣度，使得优劣度更加准确，且每次选取一个候选值作为调整后的目标运行参数的设定值时，依据的是最近更新的优劣度，提高了自动调整得到的参数的准确度。
本申请的第三实施例涉及一种参数调整的方法，第三实施例与第二实施例大致相同，主要区别之处在于：若调整后的目标运行参数的设定值和调整前的目标运行参数的设定值不匹配，还需要根据第二性能指标的指标值来评估设备基于调整后的目标运行参数的设定值运行的是否可行，再执行相应的操作。流程图如图5所示，包括：
步骤301，获取设备的第一性能指标的指标值。
步骤302，查找第一性能指标的指标值下，设备的目标运行参数的每个候选值的优劣度；候选值的优劣度是指第一性能指标的指标值下将目标运行参数设定为候选值的优劣程度。
步骤303，根据查找到的每个候选值的优劣度，选取一个候选值，作为调整 后的目标运行参数的设定值。
步骤301-303与步骤101-103类似，在此不再赘述。
步骤304，若调整后的目标运行参数的设定值和调整前的目标运行参数的设定值不匹配，获取设备的第二性能指标的指标值。
当调整后的目标运行参数的设定值和调整前的目标运行参数的设定值不一致时，表明两者不匹配，获取设备的第二性能指标的指标值；当调整后的目标运行参数的设定值和调整前的目标运行参数的设定值一致时，表明两者匹配。若为首轮的参数调整，目标运行参数的设定值预先设定一个初始值，首轮的调整前的目标运行参数的设定值为初始值。第二性能指标包括但不限于以下之一或任意组合：无线资源控制(Radio Resource Control，RRC)连接建立成功率、用户平面的承载演进无线接入承载(Evolved Radio Access Bearer，ERAB)建立成功率、无线接通率、切换成功率、无线掉线率、ERAB掉线率。
步骤305，判断第二性能指标的指标值指示设备的性能是否合格，若第二性能指标的指标值指示设备的性能合格，先进入步骤306，再进入步骤307；若第二性能指标的指标值指示设备的性能不合格，先进入步骤308，再进入步骤309。
将第二性能指标的指标值按照类型分别与对应的预设阈值进行比较，若预设个数的指标值低于对应的预设阈值，则表明设备的性能不合格，若预设个数的指标值不低于对应的预设阈值，则表明设备的性能合格，预设个数可以根据实际需要进行设定。例如：若第二性能指标的指标值包括：RRC连接建立成功率50％、ERAB建立成功率70％、无线接通率65％、切换成功率66％，对应的预设阈值分别为：60％、65％、60％、55％，若预设个数为1，此时有一个指标值低于对应的预设阈值，则表明设备的性能不合格。
在一个例子中，若超过预设次数的判断结果均为不合格时，将设备所属的不同状态下设备的目标运行参数的多个候选值的优劣度进行复原，全部恢复为初始值，预设次数可以根据实际需要进行设定，本实施例不做限定。
步骤306，获取设备的第三性能指标的指标值。
步骤307，根据第三性能指标的指标值，更新第一性能指标的指标值下选取的候选值的优劣度。
在一个例子中，根据第三性能指标的指标值，更新第一性能指标的指标值下选取的候选值的优劣度，包括：根据第三性能指标的指标值，得到优劣度的调整值；根据优劣度的调整值，更新第一性能指标的指标值下选取的候选值的优劣度。根据第三性能指标的指标值得到的优劣度的调整值更加准确，再根据优劣度的调整值更新优劣度，使得更新的优劣度更加准确。第三性能指标的指 标值对应预设的不同的优劣度的调整值，或者将第三性能指标带入预设的计算公式中，计算得到优劣度的调整值，再将优劣度的调整值和原有的优劣度相加得到新的优劣度，将新的优劣度更新为当前状态下选取的候选值的优劣度。例如：第三性能指标的指标值的指标值为5％时，对应的优劣度的调整值为2，第三性能指标的指标值为10％时，对应的优劣度的调整值为3。
在一个例子中，第一性能指标和第二性能指标为本小区的性能指标，第三性能指标包括本小区和同频相邻小区的同种类型的性能指标；其中，设备为基站。在更新第一性能指标的指标值下选取的候选值的优劣度时，不仅考虑了本小区的性能指标的指标值，还考虑了同频相邻小区的性能指标的指标值，提高了更新后的优劣度的准确性。例如：第一性能指标为本小区的上行误块率BLER 本，第二性能指标为本小区的ERAB掉线率，第三性能指标包括重新获取的本小区的总流量Payload 本和同频相邻小区的总流量Payload 邻。在一个例子中，第三性能指标与第一性能指标的类型相同，例如：第一性能指标为BLER 本，第三性能指标为最近一个预设时间内重新获取的本小区的上行误块率BLER 本和同频相邻小区的上行误块率BLER 邻。
步骤308，将目标运行参数的设定值回退为调整前的目标运行参数的设定值。
若调整前的目标运行参数P0的设定值为-88dBm，调整后的目标运行参数的设定值为-94dBm，则将目标运行参数P0的设定值回退为-88dBm。
步骤309，降低第一性能指标的指标值下选取的候选值的优劣度。
在一个例子中，降低第一性能指标的指标值下选取的候选值的优劣度，包括：根据预设的优劣度的调整值，降低第一性能指标的指标值下选取的候选值的优劣度。在目标运行参数的设定值回退为调整前的目标运行参数的设定值的情况下，直接根据预设的优劣度的调整值进行降低，提高了更新的效率。预设的优劣度的调整值根据实际需要进行设定，本实施例不做的限定。若预设的优劣度的调整值为正值时，用原有的优劣度减去预设的优劣度的调整值得到新的优劣度，将新的优劣度更新为当前状态下选取的候选值的优劣度，例如：若原有的优劣度为5，预设优劣度的调整值为1，则新的优劣度为4，则将新的优劣度4更新为当前状态下选取的候选值的优劣度。若预设的优劣度的调整值为负值时，将预设的优劣度的调整值和原有的优劣度相加得到新的优劣度，将新的优劣度更新为当前状态下选取的候选值的优劣度。例如：若原有的优劣度为5，预设的优劣度的调整值为-1，则新的优劣度为4，则将新的优劣度4更新为第一性能指标的指标值下选取的候选值的优劣度。
以下将结合两个实例进行说明。
在第一个实例中，设备为基站，第一性能指标为本小区的上行误块率BLER 本，是最近一个预设时长内获取得到的，预设时长为15min，初始化目标上行BLER 目标值＝10％，目标运行参数为P0，P0的候选值为-100dBm、-94dBm、-88dBm、-82dBm、-76dBm，P0的初始设定值为-88dBm。指标值区间与目标运行参数的每个候选值的优劣度的对应关系如下表4所示，且第一性能指标的指标值下设备的目标运行参数的多个候选值的优劣度的初始值均为0，表4中的数值为优劣度。

步骤二，查找当前指标值区间10％＜BLER 本≤15％对应的目标运行参数的多个候选值的优劣度分别为1、8、4、6、2，再根据ε贪心算法，确定候选值的选取方式，若生成的随机数x为0.08，T＝256，
Figure PCTCN2021073546-appb-000007
由于x不小于ε，则选取方式为根据优劣度选取，从目标运行参数的候选值中选取优劣度最高的候选值，则选取优劣度为8的候选值即P0为-94dBm，调整后的目标运行参数的设定值为-94dBm。
若调整前的目标运行参数P0的设定值为-88dBm，调整后的目标运行参数的设定值和调整前的目标运行参数的设定值不一致，表明两者不匹配，进入步骤三。
若调整前的目标运行参数P0的设定值为-94dBm，调整后的目标运行参数的设定值和调整前的目标运行参数的设定值一致，表明两者匹配，直接进入步骤四。
步骤三，在基站基于P0为-94dBm运行10s后，获取设备的第二性能指标的指标值，若RRC连接建立成功率68％、ERAB建立成功率70％、无线接通率65％、切换成功率66％，而对应的预设阈值分别为：60％、65％、60％、55％，此时指标值全部高于对应的预设阈值，则表明设备的性能合格，进入步骤四。
若RRC连接建立成功率50％、ERAB建立成功率70％、无线接通率65％、切换成功率66％，而对应的预设阈值分别为：60％、65％、60％、55％，有一个指标值低于对应的预设阈值，则表明设备的性能不合格，将目标运行参数的设定值回退为调整前的目标运行参数的设定值，即将目标运行参数的设定值回退为-88dBm，基站基于P0为-88dBm运行。且将预设的优劣度的调整值-1和原有的优劣度8相加得到新的优劣度7，将优劣度7覆盖表5中的8，再重新进入步骤一。
步骤四，按照以下公式计算优劣度的调整值：
Figure PCTCN2021073546-appb-000008
其中，R为优劣度的调整值，β为预设的初始邻区权重值，N为同频相邻小区的个数，
Figure PCTCN2021073546-appb-000009
为最近15min内获取的本小区的上行误块率，
Figure PCTCN2021073546-appb-000010
为下一个15min内获取的本小区的上行误块率，BLER 目标值为初始化目标上行误块率，
Figure PCTCN2021073546-appb-000011
为索引值为n的最近15min内获取的同频相邻小区的上行误块率，
Figure PCTCN2021073546-appb-000012
为索引值为n的下一个15min内获取的同频相邻小区的上行误块率。若 计算得到的R值为1，将R的值1和原有的优劣度8相加得到新的优劣度9，将优劣度9覆盖表5中的8，再重新进入步骤一。
在第二个实例中，设备为基站，第一性能指标为资源块利用率PRB利用率，是最近一个预设时长内获取得到的，预设时长为15min，目标运行参数为表征所述小区用户迁移管理的参数，即踢用户、吸用户和无操作，目标运行参数的初始设定值为无操作，其中，不同的操作通过改变小区的发射功率实现，踢用户为减小小区的发射功率，吸用户为增加小区的发射功率，无操作为保持不变，改变的幅度大小为5dBm。指标值区间在表6和表7中以状态的形式体现，根据实际经验可以将PRB利用率为[0％,30％)认为设备处于闲的状态，PRB利用率为[30％,60％)认为设备处于较闲的状态，PRB利用率为[60％,80％)认为设备处于较忙的状态，PRB利用率为[80％,100％]认为设备处于忙的状态。指标值区间与目标运行参数的每个候选值的优劣度的对应关系如下表6所示，且第一性能指标的指标值下设备的目标运行参数的多个候选值的优劣度的初始值均为0，表6中的数值为优劣度。
表6
  a＝踢用户 a＝无操作 a＝吸用户
s＝闲 0 0 0
s＝较闲 0 0 0
s＝较忙 0 0 0
s＝忙 0 0 0
以下将结合当前执行次数T为256进行说明，指标值区间与目标运行参数的每个候选值的优劣度的对应关系如下表7所示，表7中的数值为更新后的优劣度。
表7
  踢用户 无操作 吸用户
闲 3 0 2
较闲 1 3 5
较忙 4 3 1
忙 6 2 2
步骤一，根据最近15min内获取得到的PRB利用率的指标值确定所属的当前指标值区间，若获取的PRB利用率的指标值为70％，确定所属的当前指标值区间为[60％,80％)，即设备处于较忙的状态，处于上表7中的第三行。
步骤二，查找设备处于较忙的状态下对应的目标运行参数的多个候选值的优劣度分别为4、3、1，再根据ε贪心算法，确定候选值的选取方式，若生成的随机数x为0.08，T＝256，
Figure PCTCN2021073546-appb-000013
由于x不小于ε，则选取方式为根据优劣度选取，从目标运行参数的候选值中选取优劣度最高的候选值，则选取优劣度为4的候选值即踢用户，调整后的目标运行参数的设定值为踢用户，若当前的小区的发射功率为35dBm，则将小区的发射功率调整为30dBm，基站基于小区的发射功率为30dBm运行。
若调整前的目标运行参数的设定值为无操作，调整后的目标运行参数的设定值和调整前的目标运行参数的设定值不一致，表明两者不匹配，进入步骤三。
若调整前的目标运行参数的设定值为踢用户，调整后的目标运行参数的设定值和调整前的目标运行参数的设定值一致，表明两者匹配，直接进入步骤四。
步骤三，在基站基于小区的发射功率为30dBm运行10s后，获取设备的第二性能指标的指标值，若RRC连接建立成功率68％、ERAB建立成功率70％、无线接通率65％、切换成功率66％，而对应的预设阈值分别为：60％、65％、60％、55％，此时指标值全部高于对应的预设阈值，则表明设备的性能合格，进入步骤四。
若RRC连接建立成功率50％、ERAB建立成功率70％、无线接通率65％、切换成功率66％，而对应的预设阈值分别为：60％、65％、60％、55％，有一个指标值低于对应的预设阈值，则表明设备的性能不合格，将目标运行参数的设定值回退为调整前的目标运行参数的设定值，即将目标运行参数的设定值回退为无操作，基站基于小区的发射功率调整为35dBm运行。且将预设的优劣度的调整值-1和原有的优劣度4相加得到新的优劣度3，将优劣度3覆盖表7中的4，再重新进入步骤一。
步骤四，按照以下公式计算优劣度的调整值：
