5． 2 并联谐振
1、学习指导 （1）并联谐振的条件
在小损耗条件下，并谐电路的谐振频率与串谐电路的谐振频率计算公式相同。
课
而通频带则是指以电流衰减到谐振电流I 0 的 0.707 倍为界限

Q小 Q大
0
（2）并谐电路的基本特征 ①电路呈高阻抗特性； ②由于电路呈高阻抗，因此路端电压一定时，电路总电流最小； ③在L和C两支路中出现过电流现象，即I L0 = I C0 = QI。 （3）能量交换平衡 当电路发生谐振时，说明具有 L 和 C 的电路中出现了电压、电流同相的特殊现象，电源 和谐振电路之间没有电磁能量的交换，电路中的无功功率 Q=0。但储能元件 L 和 C 之间的能 量交换始终在进行，而且任一时刻，两元件上的电能与磁能之和恒等于电能（或磁能）的最大 值，这种情况我们称元件之间的能量交换得到平衡。 （4）品质因数
解析：信号源的频率大于并联谐振回路的谐振频率时，电感支路的阻抗增加，使得支路电 流减小，电容支路的阻抗减少而使得电容支路的电流增大，因此回路呈现电容特性；信号源的 振回路的谐振频率时，电路发生并联谐振，电路呈现电阻特性。 频率小于并联谐振回路的谐振频率时情况相反， 电路呈电感特性； 当信号源的频率等于并联谐 （2）为什么称并联谐振为电流谐振？相同 Q 值的并联谐振电路，在长波段和短波段，通 频带是否相同？ 解析：并联谐振时在支路中将出现过电流现象，即支路电流为电路总电流的Q倍，因此， 通常把并联谐振也称为电流谐振。相同Q值的并联谐振电路，由于在长波段和短波段中的谐振

In My Parents’ words. The difference between their childhood and mine is as vast as that between heaven and earth.When my parents were young, there was no TV, no computers nor a ny other electronic appliances in their home. Their food was simple and their clothing plain. What is unbelievable to young people today is that t hey seldom dined out in a restaurant, or traveled to a scenic spot for a holiday.In contrast to family life one generation ago, each family in China t oday has at least one TV set and many have been equipped with telep hones, computers, even cars. While the senior members of a family wat ch films on TV at home, the younger members like to play computer ga mes or talk to their friends who may live thousands of miles from them.The changes in Chinese family life mirror the economic development of our country. Without the prosperity of the whole country, our family lif e would probably be just the same as before. Times have changed, and changed, most would surely agree with me, for the better.Unit 2 Civil-Rights HeroesVocabularyI. 1. 1) decades 2) historic 3) imposed 4) racial 5) slender6) closing in on 7) settlement 8) site 9) mission 10) authorized11) terminal 12) make the best of13) exploits14) religious 15) on the side2. 1) pass for 2) stood up for 3) laid down 4) t ake on5) let (us) down 6) draw on/upon 7) come up 8). given up3. 1) The Europeans are fully confident that the Americans will not be able to justify their measures to protect the struggling American steel industry.2) Clinton is, in the eyes of Joe Klein, staff writer of the New Yorker and author of The Natural, the most talented politician of his generation and the most compelling.3) There’s not much you can do if people are really intent on destro ying themselves with drugs.4) A different experience of the world could forge a completely differe nt approach to life.5) It is our conviction that cloning of human beings is bound to cause many ethical and social problems in the long run.4. 1) As for , do not compel, capture of, have forged2) would starve, At huge risk, the mission, transport3) who abolished, liberated, In the eyes of, exploits.III.

Shortly after he achieved freedom he became a memb er of an organization that assisted fugitive slaves. He secretly returned t o the United States from Canada several times to help others to travel t he Underground Railroad to freedom. Once some slave catchers closed i n on the escaping slaves and Henson when they were on the run. He d isguised them and successfully avoided capture. In addition., later he buil t a small settlement in Dresden in Canada for escaped slaves, setting u p a chapel and a school where they could learn useful ways of making a living.

一万八千年后，天更高，地更厚，盘古像一根九百万里高的柱子伫立其间，田地永远也无法再合在一起。
