In the actual cases , there are many motors often operate on low load with low power factor and low efficiency , also there are many motors operate on the magnetic flux saturate region with high energy consumption , a large mount of energy used by ac motors is wasted due to all of those factors 在实际运行中，许多电动机经常处在低效率、低功率因数的欠载运行状态下，还有许多电机则是铁芯磁通常进入饱和区的高能耗电机，这些因素均可导致大量电能的浪费。

As we all know , the heat transfer of geothermal heat exchanger ( ghe ) is affected by a lot of factors , where groundwater advection has a comparatively great impact indicated by experimental data . while almost all the design tools for ghe are based on principles of heat conduction and rely on some estimate of the ground thermal conductivity and volumetric specific heat . however , the large part of vertical u - type pipe lies in the saturated soil , especially in zones along the coast or with plentiful groundwater , which will be affected by groundwater advection greatly 但是对于垂直u型埋管来说,管段大部分位于土壤饱和区内,实际上其穿透的地层中总是存在着地下水的渗流,尤其是在沿海(河、湖泊)地区或地下水丰富的地区,埋管的传热性能大部分都受到地下水渗流的影响,此时土壤内发生的是热传导和地下水渗流共同作用下的复杂的、非稳定的传热传质过程(简称热渗耦合传热过程) 。
The mutual inductor of electric current and voltage mutual inductor play an important role in relay protection . prevent from ct differential to protect and miss movement an important subject that the generatrix is protected on the saturation , put forward two electric current pass zero hour linear to spread person who become put into differential to protect in ct in recent years , avoid ct saturation district , can judge the bus bar trouble correctly 但是在母线区外发生短路故障(特别是故障电流含有大量非周期分量)时， ct会出现饱和现象， ct饱和后，不能正确地传变一次侧电流，从而使二次电流发生严重畸变，产生很大的差电流，这样就容易引起误动作。防止ct饱和时差动保护误动作一直是母线保护的一个重要课题，近年来提出的在ct二次电流过零时的线性传变区投入差动保护，避开ct饱和区，能对母线故障做出正确判断。
Study shows that great rainfall influences soil slope safety factor markedly , magnitude of rainfall intensity has a great influence on slope safety factor for steep slope under certain coefficient of saturated conductivity , the surface plant roots affect unsaturated zone seepage field distribution and postpone unsaturated zone moisture content ' s increase , so the soil slope safety factor is enhanced finally 分析结果表明，在土体饱和渗透系数一定的条件下，强降雨对土坡稳定系数影响显著；土坡越陡，降雨强度大小对土坡安全性影响就俞显突出；土坡表层植物根系的存在影响非饱和区渗流场分布，可以延缓非饱和区含水量的增大，土坡稳定系数得到提高。
The scheme is on the basis of the heterogeneity of soil water content ' s horizontal spatial distribution in the region and the evaporative power of relatively saturated region . if the probability density function ( pdf ) of soil water content ' s horizontal spatial distribution and the evaporative power of relatively saturated region are attainable , the mean evapotranspiration flux of the region can be calculated 该方案以区域内土壤水分在水平空间上分布的非均匀性和相对饱和区地表蒸发力为基础，在已知土壤水分水平空间分布律的概率密度函数( pdf )和饱和区地表蒸发力的前提下，实现区域平均蒸发散量的计算。
