查询词典 high-frequency

By adding an equivalent harmonic impedance in the branch circuit of power grid, this HAPF could force all the harmonic currents flow into passive power filters, which resulting in eliminating harmonic contamination more effective. And using the capacitive feature of PPF in the fundamental frequency, this HAPF could compensate fixed-capacity reactive power without increasing APF's burden. Moreover, in order to decrease APF's cost, the fundamental voltage will largely be endured by capacitor in view of the series resonance circuit tuned at the fundamental frequency, so the APF just bears little harmonic voltages.

其基本工作原理是：有源部分等效于在电网支路中串联了一个谐波阻抗，该谐波阻抗对基波电流不起作用，而对谐波电流产生很大阻碍作用，迫使谐波电流流入无源滤波器，从而达到滤除谐波的目的；同时新型注入式混合有源滤波器还充分利用了无源滤波器的无功补偿功能，在不增加有源部分容量的前提下，可以提供一定容量的无功功率；由于有源部分承受的电网基波电压不大，也没有基波电流流入，因此逆变器容量小，初期投资较小。

总之，热处理过程中磁化率的变化能非常灵敏地反映磁性矿物的转化情况，而且，这种转化往往与样品所经历的土壤化作用强度密切相关，因此，TDS可做为分析成土作用强度和古气候变化的一种新方法。

Therefore, in this chapter, I will research into the conflict and contradiction of the paternity. Also, in this novel, the father's behavior of "He who loves well chastises well." is quite suspicious, one of the reasons is that the father thought his son belonged to him. And then, this thesis quoted Lacan's theory to touch upon that someone who has accepted the concept of patriarchal society, he will be influenced for his whole life. That also reveals that human being has no choice sometimes in this society.

因此本章会先就父子关系的冲突与矛盾做深入的探讨，小说中的父亲似有对儿子爱之深责之切的行为，其原因可能在於父亲将儿子视为所有物所致；其次，论文将引用拉冈相关理论，讨论在父权社会中，不论身分为何，只要是已受父权社会观念根深蒂固影响的人物，终生都将受其所苦，此也揭示出人生存於社会上的无奈。
