Constrained to technologies, the lead - acid battery mainly adopted traditional charging methods such as constant voltage, constant voltage with current limitation, constant current, etc. the charging current of these methods cannot match efficiently the acceptance curve of the lead - acid battery proposed by j. a. mas. as a result, some of these methods have a low time efficiency and incompleteness charging. and some of them lead to overcharge and gas - generation, which will result in low - efficiency, time - consuming and prone - to - damage of the charging operation
鉛酸蓄電池由於受到技術條件的限制,其充電主要採用恆壓、恆壓限流、恆流等常規充電模式,這些方法的充電電流未能有效的遵從馬斯所提出的可接受充電電流曲線,因而有的充電方法時間效率低、充電不完全;有的則存在著過充電和析氣等現象,並導致充電過程的低效,耗時和易損。In this paper, the over voltage induced by re - ignition, rules of breakdown in vacuum contact clearance, factors which influence dielectric strength of clearance and characteristics of re - ignition when vacuum switchgear switch capacitor banks are analyzed. the conclusion is that the breakdown of clearance in vacuum interrupter is the direct cause which inducing re - ignition of vacuum circuit - breaker in capacitor banks ’ switch. particle breakdown is the essential reason to induce breakdown in clearance of vacuum interrupter, although mechanical characteristic of vacuum circuit - breaker is another factor
本文通過對真空開關投切電容器組重燃過電壓、真空觸頭間隙擊穿機理及影響真空間隙介質強度的因素、真空開關投切電容器組重燃現象特點進行分析研究發現,真空滅弧室斷口的真空間隙擊穿是導致真空斷路器投切電容器組重燃的直接原因,其次是真空斷路器機械性能的影響,而微粒擊穿是導致國產真空滅弧室真空間隙擊穿的根本原因。Taking ti alloy tc11 electron beam welded work - piece as research object, which is the conventional material of aero engine compressor blisc, the fatigue damage evolution law of fatigue damage action in the area of welded joint based on damage mechanics theory is analysed, and fatigue damage model, which macro - parameter and micro - damage characteristics are related, with fractal geometry - a new conception of modern mathematics is set up in this paper. it tries to research the measuring method of fatigue fracture fractal dimension and the relationship of fractal damage variable with fatigue life. it also sets up the welded joint fatigue damage fractal evolution equation
本課題以航空發動機壓氣機葉盤常用材料鈦合金( tc11 )電子束焊構件為研究對象,對焊接接頭的疲勞破壞行為,基於損傷力學理論分析其疲勞損傷演化規律,應用現代數學的新概念? ?分形幾何學理論,建立宏觀參量與細觀損傷特徵相聯系的疲勞損傷模型,研究疲勞斷口分維數測量方法以及分形損傷變量與疲勞壽命之間的關系,建立焊接接頭疲勞損傷分形演化方程。
