Alteration in excitability and conductivity of a nerve or muscle during the passage of an electric current through it 电紧张当电流通过时,某一神经或肌肉产生的易激动性和传导体的变化
Endplate potentials , acetylcholine potentials , and electrotonic potentials were recorded from the motor endplates of isolated diaphragms from acute late septic and nonseptic rats 记录急性迟发性脓毒血症和非脓毒血症大鼠的离体横膈运动终板上的终板电位、乙酰胆碱电位和电紧张电位。
But the grid voltage is different in many countries , so the research of an inverter , which can be used in many countries , will become a trend . a grid - connected inverter in grid - tied and off - grid modes has many advantages such as peak shaving to reduce the overall cost of power by generating during peak load hours in grid - tied mode , and standby generation to provide power during system outages until service can be restored in off - grid mode 由于世界各国电网电压的规格繁多,能够研制出适合于多个国家电网电压规格的逆变器将是未来发展的一种趋势;独立与并网双模式运行的逆变器由于具有缓解电网用电紧张、减少发电站的发电量、在电网断电时对负载起不间断供电的作用等优点,也成为现在研究的一个热点。
Directing against the problems of shortage of electric power during summer and winter seasons in the region of nanjing city , a scheme of heat , electricity and cool co - generation by using natural gas has been put forward , and techno - economic analysis for combined schemes of four kinds of different gas turbines with the refrigerating machine in a common residential quater being carried out , the suitability as well as strong and weak points of each scheme being expounded 摘要针对南京地区冬夏季用电紧张问题,提出住宅小区采用天然气热电冷三联产的方案,并就某普通住宅小区4种不同燃气轮机和制冷机组的组合方案进行技术经济分析,阐明各方案的适用性和优缺点。
