前者期望条件总是成立，而后者期望两个值不匹配。
The former expects the condition to always be true while the latter expects the two values to be mismatched.
v——将匹配意义进行逆反——即选择那些不匹配搜索条件的行。
V — Invert the sense of matching — that is, select lines that don't match the search criteria.
例如，熟悉IBMWebSphereApplicationServer的读者可能想知道，为什么不直接在SSLPEER过滤或出口的匹配条件中包括issuerDN。
Readers familiar, for example, with IBM WebSphere Application Server might have wondered why not simply include the issuerDN in the SSLPEER filter or in the matching criteria of an exit.
本文利用UA0914声强耦合腔产生的同一声场条件，测量声强测量系统两通道之间的传递函数，进而对两通道间的相位不匹配误差进行修正。
The phase mismatch errors are corrected by measuring the transfer function between two channels at the same acoustic field provided with B&KUA0914 inside in-tensity coupler.
工艺条件一定，压力决定了整个装置的处理量，处理量与压力条件不匹配，会造成产品分布不达标或者剂耗增大。
When the unit capacity is not well cooperating with the pressure at certain process conditions, product quality decreases or catalyst loss increases.
