近年来,浙江大学有关人员在国家自然科学基金的支持下,开展&固态功率开关及短路限流技术的研究&,提出了一种全新的固态短路限流技术,具有许多灵活的控制方式,完全有条件开发成一种性能优良的短路限流装置。

L Intelligent three-phase charge mode: We adopt constant current technology at the beginning of charge, which can made current invariable and avoid battery broken or accelerating battery aging. It can convert to constant- voltage and current-limiting charge when charge voltage achieves upper limit voltage, which can improve effectively the capacity conversion efficiency of battery. Trickle and floating charge make each single cell battery constant receive electricity and ensure battery capacity can be recall most, which solved the unbalanced phenomenon of single cell battery and avoid the danger of voltage change and the end of battery charge, extend battery life.

l 智能三阶段充电模式:充电初期采用恒流技术,使充电电流恒定,避免损坏电池,加速电池的老化;充电电压达到上限电压时自动转换为恒压限流充电,有效的提高了蓄电池的容量转换效率;涓流浮充使各单体电池均衡受电,保证电池容量得以最大限度恢复,有效解决单体电压不均衡现象,避免了市电电压的变化和蓄电池充电的末期造成的蓄电池过压充电的危险,大大延长了蓄电池的使用寿命。

Allowable current density is firstly confirmed by analyzing the variation of current efficiency with current density. Effects of content of ammonia ions, pH value and the content of sodium formate upon the throwing power, covering power and ability of anti-impurities, were measured.

首先通过分析电流效率随电流密度的变化情况确定了镀液的许用电流密度,然后测定了氨的含量、镀液pH值、甲酸钠的含量等因素对分散能力、深镀能力、抗杂性能等镀液性能的影响。

And base on topological structure of SVG for three-phase three-wire system, it puts forward a control method of compensation current which is based on forecasting current strategy to improve the tracking accuracy of dictation current.

同时,在三相三线制电压型静止无功发生器拓扑结构的基础上,论证了两种直接电流控制方法:滞环控制和三角波控制。

The main formation causes of storm current are convergence of tidal current and special topography and the strength of storm current depends mainly on the released disordered potential energy .

对滦河口近海激流的形成进行了讨论,认为潮流的辐合和特殊的地形是激流形成的主要原因,而激流的大小则主要取决于无序位能的释放量。

Although forest canopy layer could prevent splash erosion effectively, clay was taken away by overland flow and run off easily, the erosion amount became less after removing the forest canopy and surface soil, while the splash erosion still produced in the surface layer; the splash function weakened after having water current, the starting particles were less than bareland, so removing the surface disturbed soil made the erosion amount and clay less, silty sand more than bareland, but unsteady, the wear and tear energy used by raindrop splash and current function for overcoming sediments separating and starting were comparatively large, sediments were very difficult to be started and transported, it explained that forest root systems could increase anti-erosion capability of forest vegetation, make rainfall-current system splash and export finer particles than bareland.

虽然林冠层能有效防止溅蚀的发生,但坡面流还是能带走粘粒部分,粘粒还是容易流失。去除林冠和表层土后,侵蚀量变得更少,但表层还是会被溅蚀,有水流后,溅蚀作用减弱,颗粒起动的比裸地的少,所以,去除表层扰动土后,侵蚀量更少,粉沙多,粘粒比裸地更少一些,但不稳定,雨滴击溅和水流作用用于克服泥沙分离起动损耗的能量较大,很难被起动输移,这说明森林植被根系的作用增加了林地植被的抗蚀力,使降雨一水流系统仅能溅起输出比裸地坡面更细小的泥沙颗粒。

So current increases. The increased current strengthens the space-charge effect further. So on and so on, the negative-resistance phenomenon occurs. For mathematical method limiting, SID's potential can't be solved outside channel or under middle, even big current.

对于SITH来说,由空间电荷效应所引起的阳极端场强增大现象导致空穴的抽出效应加剧,这部分抽出的空穴漂移至沟道中促使势垒降低从而加大了电流,而电流的加大又进一步加强了空间电荷效应,如此循环,造成了SITH特有的负阻转折现象。

Neutral Current Neutral current is the current that flows in the neutral leg of a paralleling system. Often, this term is used in reference to circulating currents or cross currents.
