菜工程中有一台直流电动机，额定功率1500kW，额定电压660V，额定电流2500A，采用晶闸管变流器调速，速度反馈不可逆速度调节系统，变流器主电路为三相全控桥接线，电网额定电压10kV，电压波动系数0．95。请回答下列问题。 若变流变压器阀侧绕组390V，变流器最小出发延迟角为30°，计算该变流变压器输出的空载...
One approach to deduplicating FHIR resources is simply comparing the entire resources. This, however is hard. In XML, attribute order may be different but the resources may still be the same. In JSON, objects need not be in the same order at all. On top of that comes non-significant whi...
