More than 90% of the total incidence of typhoid and paratyphoid were typhoid previously, as the widely use of Vi bacterin, in the middle of 90s in 20th century, the popular strain changed, in some provinces the cases of typhoid decreased, but that of paratyphoid increased largely, with the outbreak trend from spot to part and from inshore provinces to backland provinces. In recent years, paratyphoid becomes the main infectious diease in some areas, and ofen develop to serious epidemic situation. So setting up a rapid and accurate detecting metod is necessary.

以前我国伤寒发病占伤寒副伤寒总发病的90%以上，后来由于伤寒Vi疫苗的广泛使用，20世纪90年代中期，流行菌株发生转变，我国部分省份伤寒病例逐渐下降，而由甲型副伤寒沙门氏菌引起的副伤寒病例却大幅上升，并呈现由散发到局部暴发，由沿海省份向内地省份推进的流行趋势，近几年来成为我国一些地区传染病突发事件的主要病种，常发展成重大疫情，急需建立快速、准确的诊断方法。

This makes the driving chain flexible to such an extent that it can adapt in both the horizontal plane and in the vertical plane to the scraper chain conveyor or the hollowed section intended for guiding the chain.

At last ,it drew a conclusion that summarined the design thought of permanent magnetic brushless DC motor control system after absenting waves of controllers work . Permanent Magnetic Brushless DC motor control system canbecome main power source in ship electric propulsion field ,and the research have important s signification.

最后，在控制系统实际运行时对波形进行了观测，给出了结论，总结了无刷直流电机控制系统的设计思想，提出永磁无刷直流电机将成为船舶电力推进的主要动力，对其控制系统的研究具有广泛的应用价值。

Reapings and Sowings)（"And every science, when we understand it not as an instrument of power and domination but as an adventure in knowledge pursued by our species across the ages, is nothing but this harmony, more or less vast, more or less rich from one epoch to another, which unfurls over the course of generations and centuries, by the delicate counterpoint of all the themes appearing in turn, as if summoned from the void."

&任何一种科学，如果我们不是把它理解为一种表达力量和控制能力的工具，而只是当作我们人类世代所推进的知识探险，那她不是别的，就只是那个可以名之为和谐的东西。从一个时代到另一个时代，这个和谐或广或窄，或丰或乏，历经一代又一代，一个世纪又一个世纪，依次所显现出来的对于各个主题的精妙映照，仿佛就是琢空而现。&
