By compared with the simulation results and the experiment results , we come to the conclusions that : ( 1 ) circuit with assistant network can widen soft - switching extent in lagging arm , reduces duty - cycle loss on the secondary , diminishes switching dissipation of inverter spot - welding power source . ( 2 ) the range of resonant capacitor , the important factor to soft - switching process , not only affects zero - voltage turn - off of power switches , but also affects the range of zero - voltage turn - on of power switches . so resonant capacitors must be considered according to many aspects ; ( 3 ) it easily fulfils soft - switching condition in lagging arm as leakage inductance of power transformer increases , but bigger leakage inductance of power transformer increases opening dissipation of transformer and decreases efficiency of soft - switching inverter power source 通过仿真结果与软开关点焊逆变器试验结果的对比分析,得到了如下主要结论:采用辅助网络可以完全拓宽全桥软开关逆变器的滞后桥臂软开关范围,减小了次级占空比丢失,降低了逆变电阻点焊电源的开关损耗;谐振电容是影响软开关工作状态的重要因素,其大小不仅影响开关管的零电压关断,同时也影响开关管的零电压开通范围,因此,谐振电容应该综合考虑;功率变压器漏感越大,越容易满足滞后桥臂的软开关条件,但是大的漏感也使变压器的通态损耗增加,降低了软开关逆变器的效率。
In the case of uncorrelated noises , it is shown that only the fluctuation of degradation reaction rate can induce a switch process , and the mean first passage time ( mfpt ) between the high concentration state and low concentration one is decreased when the noise intensity of degradation reaction rate is increased 可以看到源于蛋白质基本合成率的噪声强度不能引起基因状态的转变(即基因的开关)而源于降解率噪声强度则能够实现这种开关。当进一步研究在降解率波动作用下基因从一个态跃迁到另一个态的平均首通时间( mfpt )时可以看到此时随着这个波动强度的增加, mfpt是单调递减的。
So the thesis , referring to the theories related to measuring credit risk abroad , combining them with the fact of switching process in china , has formed risk survey system model , which properly solves credit risk survey problem lying in off - trade assets under the demestic circumstances . that model is working in a sense and foresighting to a degree . we analyze risks in order to control them better . according to the reality of china and the need of development , the thesis recognizes that we must carry out comprehensive risk management , besides it lists the fundamental framework and indispensable elements of comprehensive risk management 作为商业银行的风险的研究必须坚持定量和定性相结合,本文认为我国现阶段商业银行的风险主要是体制、政策造成的,是由各种政策性因素引起进而表现为巨大的信用风险,因而本文借鉴了国外有关测量信用风险的理论,结合中国的实际,形成了风险度量制模型,较好的解决了国内条件下非交易资产的信用风险度量问题,既具有一定的实用性,又具有较强的前瞻性。
The economical switching process enlarged the disparity of people to consume the social public goods . thus , in the current , under the situation of difficulty of the bottom rung of finance and shortage of countryside public goods , the research has the extremely significant theoretical and the practical significance 我国在多年的经济转轨过程中,经济年平均增长率达到9 % ,但是这种高速发展是以非对称型的转型为代价的,即拉大了人们对社会公共物品享有水平的差距,突出表现在了城乡公共物品的供给上。
The physical characteristic of forming plasma within resonant cavity was revealed , i . e . the forming mechanism is a switching process from the ionization caused by strong electric field at the initial stage of mpt ' s start to another ionization caused by joule ' s heat at the stage of mpt ' s steady work . the main influencing factors of mpt ' s steady work were studied . anther pointed out the matching between pressure in resonant cavity and microwave power is the determinant factor to the plasma whether stabilization or extinguishing 分析了mpt谐振腔内微波能量的转换过程,揭示了其内等离子体的形成是由mpt启动初期的强电场电离形成放电区过渡到稳定工作期的热电离形成稳态等离子体区这一物理本质;研究了影响mpt稳定工作的主要因素,指出微波有效功率与谐振腔内气体压强的匹配是维持等离子体稳定、避免等离子体消失、放电区熄灭的关键因素。
