Anesthesis was performed by interscalene brachial plexus block.the onset and duration of analgesia,the level of block as well as adverse effects were recorded.hr and map were measured before anesthesia,5,10,30 and 60 minates after anesthesia.results:the onset time of block was significantly shorter and shivering was significantly lower in groups two and three as compared with group one.there was significant difference in the duration of anesthesia between group two and group three.

肌间沟法行臂丛神经阻滞，观察阻滞起效时间及持续时间、神经阻滞节断数、术中镇痛质量、不良反应以及注药前、注药后5、10、30、60分时心率和平均动脉压。结果：二、三组麻醉起效时间短于一组（p＜0.05）；麻醉持续时间二、三组长于一组但差异无显著性；二、三组组间比较差异有显著性；各组阻滞节断数、术中牵涉痛发生率、hr及map差异无显著性；一组寒战发生率高于二、三组（p＜0.05）。

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.

研究表明，穗粒数的减少是玉米抽雄开花期水分胁迫下产量降低的主要限制因子，而秃尖增长和行粒数减少是穗粒数降低的主要因素，说明干旱导致雌穗发育受阻，花期不遇，籽粒败育率增加。

The study results show that the dispersion of travelling wave is mainly caused by earth mode; Compared with aerial mode earth mode is greatly influenced by the factors such as ground conductivity, line average height above ground, bundle config...

研究结果表明：行波色散主要由地模引起；行波中地模受大地电阻率、线路高度、分裂导线数、分段地线、连续地线等因素的影响较大，而线模受到的影响较小，因此将线模作为故障定位用行波传播模式比较适宜。
