The main content of this dissertation includes: 1. Research on the theory of ultrasonic power supply, introduce its development process. On the basis of these, fix on the scheme of medical ultrasonic low-power supply. 2. According to the principle of modularized design, divide medical ultrasonic low-power supply into four parts. They are power amplify circuit, power control circuit, frequency automatic tracking circuit and matching circuit. Separately research on their theories and design their circuits and necessary programs, especially, effectively resolve the problem tracking the supersonic vibration system with a narrow syntony frequency bandwidth and a high swing. 3. The matching experiments gain good result, and prove that medical ultrasonic low-power supply is entirely up to the mustard on intellectualization, wide band of working frequency, steady output and high efficiency.

There maybe be some differences between the original assumption PDF to the new one generated by sparse data input and we suggested to using the truncated probability distribution function for modeling this situation.

针对此分布不匹配的问题，本研究首先提出使用截尾分布机率密度函数(truncated probability distribution function)的概念来近似。

The development of the auto spare parts industry is unbalance at present in China and this is easy to lead to the auto quality problem, auto air-condition noise is mainly resulted from also the system matching unideal.

国内汽车零部件行业水平的参差不齐容易导致整机出现质量问题，汽车空调异响也是由于系统匹配的不合理造成。

An adaptive control law is thereafter constructed. It is proved by Lyapunov stability theory that the solution of the closed loop system is uniformly ultimately bounded.

首先研究了一类带有时变延迟和常数延迟的匹配非线性不确定性中立型系统的鲁棒镇定问题。

This is determined by the recounting stategy of woman writers who match it with the city reading market.With female sensitivity and sharp observation they jot down various present life fragment of dramatic color,vivid plots in turns and twists,even oddness,which satisfy the reader's need to some extent.However,the biggest problem of legendary recounting affecting female metroplis novels is the modelization in creation,and severe untruthfulness of the story.This should not be neglected by woman writers if they are to surpass themselves.

它们在阅读市场化时代之所以能引人注目，显然不仅仅在于女作家们紧追中国日益都市化和市场化的历史步伐，同构性地刻画了中国都市向现代化演进的轨迹，并由此构成了中国当代都市的巨型寓言，也不仅仅在于女作家们发现并提出了女性在走向工商业都市文明的历程中，所必须重新审视的生存和价值问题，更在于女作家们凭借自身对阅读市场的敏感而迅捷地体察到了市场和读者的要求，并在此基础上确立了与之相匹配的叙事策略。
