更多“点进率 （Click Rate)是指A.网络广告被点击次数与显示次数之比B.网络广告被点击的频率C.网络”相关的问题
A、泄漏检测的灵敏度：泄漏检测的灵敏度是泄漏检测系统所能检测出管道泄漏量的范围大小。Sensitivity of leak detection： the sensitivity of leak detection is the extent to which the leak detection system can detect the amount of leakage in the pipeline.
B、泄漏点定位精度：泄漏点定位精度是指当发生不同级别的泄漏时系统所能确定泄漏点位置的范围。Location accuracy of leakage point： location accuracy of leakage point refers to the range that the system can determine the location of leakage point when different levels of leakage occur.
C、泄漏检测的实时性：泄漏检测的实时性是指管道从开始泄漏到被检测出泄漏的时间长短。 Real-time leakage detection： real-time leakage detection refers to the length of time from the beginning of pipeline leakage to leakage detection.
D、可靠性：可靠性是指在给定的时间内系统正常运行的能力。Reliability: reliability is the ability of a system to function properly for a given period of time.
E、误报率和漏报率：分别是指发生误报或者漏报的次数占总检测次数的比例。False alarm rate and false alarm rate: the ratio of false alarm or false alarm to the total number of tests, respectively.
F、适用性：指泄漏检测系统能否对不同的管道环境(温度、压力、流量、湿度等)具有抗干扰性Applicability: it refers to whether the leakage detection system can resist interference in different pipeline environments (temperature, pressure, flow rate, humidity, etc.)；
G、性价比：指的是检漏系统所能提供的性能与建设、运行及维护费用的比值。Cost performance: refers to the ratio of the performance provided by the leak detection system to the construction, operation and maintenance costs.
