According to this method , a new matching criterion of coupling slots is derived for the series - series feeder and the shunt - series feeder 按照同样方法，对串串、并串形式的馈电装置，导出了新的耦合裂缝匹配设计准则。
The design , construction and installation , as well as operation management of power - receiving devices of users shall be consistent with the state standards or the standards of the power industry 用户受电装置的设计、施工安装和运行管理，应当符合国家标准或者电力行业标准。
Theories analyzing and tests show that the devices not only can do credible and quick judgment , but also have particular record to every time of stealing power energy 理论分析和模拟试验均表明防窃电装置能可靠、准确、迅速地对三相供电系统中各种窃电现象做出判断，而且对每次窃电都有详细的窃电记录。
To resolve this problem , this dissertation author researches deeply and makes two preventing power theft devices which be used in three - phase power supply system including three - phase three - line system and three - phase three - line system 针对这种情况，本论文作者针对三相供电系统中窃电及其检测技术进行了详细研究并研制了三相四线和三相三线计量防窃电装置。
They can be produced with different electrode constructions for various discharge rates and widely used in the fields of electrical equipments , communications , lighting , upsand the starting power for diesel engine , and solar energy system , etc 广泛应用于电器、电讯、照明、不停电装置的备用电源和直流操作电源，以及油机、直流电机的启动电源、交通运输工具的直流电源等，也可与太阳能装置配套使用。
The impedance matching criterion that the sum of all the radiating slot normalized conductances is equal to 2 for the inner feed , and also the sum of all the coupling slot normalized impedances for the series - shunt inner feeder is equal to 2 are verified by using microwave network theory 采用微波网络理论，在内部馈电情况下，分别对一条辐射波导上辐射裂缝的归一化导纳和为2的匹配设计准则，以及对串并形式馈电装置，对耦合裂缝的归一化阻抗和为2的匹配设计准则进行了证明。
The controlling box collects the temperature and the humidity of the experiment box and the temperature of the water tank with platinum resistance transducer that has three paths . then they are sent to the microprocessor 89 c55 to dispose by a / d and sent to the d / a to be an 4 ~ 20 ma output of simulant value . at the same time , the outputs of six paths switch quantity drive respectively the relaies of heightening temperature reducing temperature alarm and so on “恒温、恒湿控制箱”由三路铂电阻传感器采集试验箱的温度、湿度和水箱的温度，经12位a d送至微处理器89c55处理，送至d a输出4 20ma模拟量，同时，输出六路开关量分别驱动加湿1 、加湿2 、升温、降温、除湿、报警等继电装置。
