This article trend research and current situation of computing technology analyze in survey, through to simple network familiarity that trend calculate, take circuit of simple equivalence as an example, carry on circuit voltage and calculation that power loss of the first part and the concluding paragraph mainly, and then regard a ring network circuit as the main example and carry on the detailed trend to calculate, calculate all nodal voltage power losses, use ATP software to carry on artificial calculation with this example again, it's a pity ATP software emulation has not succeeded.

该文在综述了潮流计算方法的研究和现状分析，通过对简单网络潮流计算的熟悉，主要以简单型等值电路为例进行电路首尾的电压和功率损耗的计算，再以一环网电路为主要例题进行详细的潮流计算，计算各节点的电压功率损耗，再以此例题用ATP软件进行仿真计算，可惜ATP软件仿真没成功。

In view of this, a new single phase PFC circuit which uses the Bridgeless PFC power module and partial PFC control method is presented.

但是由于该PFC电路采用不可控整流桥，使用的功率器件数量较多，导致功率损耗较大，且使用的PFC升压电感较昂贵，因此具有效率较低和成本较高等不足。

Controlling the activity factor (in order to reduce interference and power consumption) can include: reducing the power level, prohibiting transmission of one or more devices, schwduling the transmission activity according to a stored timetable (actualised by location information or congestion bulletins).

控制活动因数(以便减少干扰和功率损耗)包括减少功率电平、禁止一个或多个设备的传输、根据所存储的时间表(该时间表是由位置信息或拥挤公告实现的)调度传输活动。

When precalcined at 930℃, MnZn power ferrites have highest initial permeability and density, lowest power losses.

当预烧温度为930℃时，MnZn功率铁氧体具有最高的起始磁导率和密度，最低的功率损耗。

Using the new concept, It is clear to identify losses of different wheelings without any hypothesis, and these losses satisfy the superposition theorem.

从而使得各个电源在某个支路内流经的功率和产生的功率损耗满足迭加定理，便于实际应用。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
