Objective: In order to solve the problem of the decreased portal inflow, decreased metabolic function and dangerous varicosis in portal hypertension, portal arterialization and complete shunt was applied in the treatment of canine model of portal hypertension, which was made by thread embolization in the portal vein.

目的：对丝线栓塞性门脉高压模型犬进行PACS手术和传统SRS手术、PCDV手术，分别观察不同术式对门静脉血流动力学的影响。

The arterialization of portal vein was brought forward for the decreased hepatic blood supply after shunt of portal vein to vena cava by Cohn in 1952, he thought, the total blood stream of liver decreased largely.

门静脉动脉化最初是由Cohn于1952年根据门静脉高压门腔分流术后肝脏供血大量减少而提出的。

The foundation of this system provides a good reference to promote the standardization and intelligence of the overhaul and maintenance of vacuum switches. This paper develops a special HF pulse power supply for internal pressure estimation, which achieves the output of HF-HV sinusoidal pulse wave whose frequency and amplitude can be modified respectively, and meets the design requirements according to the results of Simulink simulation and practical experiments. With the help of AT89S52, this paper designs an I~2C serial bus based signal detection system for peak value signal acquisition of HF pulse currents, which communicates with the upper computer by asynchronous serial communication for uploading the data. In the upper computer, a human computer interface is developed by Matlab software, whose functions are to do some computation and graphic display, such as calibrating the relation curve of vacuum degree and peak value of HF pulse currents, vacuum degree computation, and vacuum lifetime evaluation analysis basing on grey forecasting model as well as making relative suggestions.

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
