The analysis included the principal of oscillator , the selection of the topology, the characteristic of some frequently-used LC VCOs and some design tips on designing inductors and varactors, the model of phase noise of Leeson and Hajimiri ,estimation of phase noise ,etc.

然后论文对开关电容调谐的LC VCO设计理论进行了详细的分析，包括振荡器工作原理、VCO性能指标、VCO常用结构、片上电感和变容管的相关理论、开关电容调谐理论、Leeson和Hajimiri相位噪声模型，相位噪声估计等。

Building time and jitter of the Marx generator are mainly depend on work state of spark gap switch during operating. Meanwhile they are related to amplitude and polarity of trigging voltage.

Marx发生器建立时间及抖动与Marx发生器中球隙开关的工作状态有关，同时与开关的触发电压幅值及极性有关。

There are two types of switches:'Heavy'X-shaped ones and'Soft'round ones Soft switches are activated when any part of your block presses it.

当轻型开关被你的积木压住的时候就启动了。重型开关需要更大的压力。

There are two types of switches :"heavy"X-shaped ones and "soft" round ones soft switches are activated when any part of your block presses it.hard switches require much more pressure,so your block must be standing on its end to activate it.

有 switches：&的二类型重的\&X-作形了一和把他弄圆当你的区段的任何部份压 it.hard 开关的时候，软的开关被刺激需要更多压力，因此你的区段一定在它的结束上站立刺激它。

Chapter 4 is contributed to the numerical analysis on Y-shaped structures. The contents of this chapter include the transport properties of the Y-shaped quantum switches and the forming conditions for switching.

第四章集中对Y型量子结构进行了数值模拟工作，研究内容包括Y型量子开关的电子输运性质和Y型量子开关的形成条件。

Finally there is a third type of switch shaped like this: It teleports your block to different locations,splitting it into two smaller blocks at the same time.

最后，第三种形状的开关是这样的形状：；这个开关把你的积木传送到不同的地点，并把积木分割成两个更小的积木。

The failure modes of the optical switch were analyzed, which includes:stiction, mechanical fracture, delamination, fatigue and so on. The package ofthe optical switch array was designed.

分析了引起光开关失效的几种主要形式：粘连、机械断裂、分层、疲劳等，并对光开关阵列的封装进行了设计。

Xvii New or remanufactured solenoids must be used on all starters.

所有的起动机必须用新的电磁开关或翻新的电磁开关。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
