A swimmer with a snorkel can still breathe, but notice that snorkelers float right on the top.

一个游泳的人能用一根通气管呼吸，但要注意到他的通气管恰恰完全浮出水面。

A swimmer with a snorkel can still breathe, but notice that snorkelers float right on the top. Were they to try sinking underneath, even a moderate amount, the same thing would happen.

一个游泳的人带着通气管仍然可以呼吸，但是需要注意这个通气管必须浮在水上，他们尝试沉入水下，甚至是适当很深的水，相同的事情将会发生。

The two can cause ultrastructural pathogenesis widely in many organs and tissues such as hepar, pancreas, lien, ren, pulmo, cerebral, cerebellum, cor, muscular and so on, of them ,caused by i~olates YG97 and Y98 more obvious in epithelial cells of digestive tract and unobvious in epithelial cells of respiratory tract ,but ultrastructural pathogenesis caused by NDV strain F48E8 ,more obvious and more serious in glandularis and muscularis ventriaculi and in epithelial cells of respiratory tract .

将鹅源分离株YG_(97)、鸡源分离株Y_(98)和NDV强毒株F_(48)E_8感染SPF鸡，运用扫描电镜和透射电镜观察该二株病毒对机体细胞的影响，结果显示三株禽副粘病毒均引起机体肝、胰、脾、肾、肺、小脑、大脑、心和肌肉等实质器官组织细胞的超微病变，其中YG_(97)和Y_(98)引起消化道粘膜上皮细胞发生微绒毛脱落、纤毛脱落、分泌颗粒增多、细胞游离面破溃等显著的超微病变，引起气管粘膜上皮细胞的不显著超微病变；F_(48)E_8强毒株引起胃粘膜显著而严重的超微病变；还引起气管粘膜上皮严重的超微病变。

According to the characteristics of gas-collector pressure and suction-control of blower system for coke oven in Xiangtan iron and steel company, primary system is developed. Fuzzy control technology and routine PID technology are combined, and the control method of the pressure of gas collector in coke oven is given based on the fuzzy theory ,then decoupling control is adopted for coupling phenomenon.

针对湘钢焦炉集气管压力和鼓冷系统吸力控制特点，对原有系统进行改造，将模糊控制技术和常规PID控制技术相结合，提出了一种基于模糊理论的焦炉集气管压力控制方法，结合相邻通道的波动引起的耦合现象，采用模糊解耦原则进行解耦控制。
