查询词典 induction bridge

That is to say, during the starting process of induction motor, hold-off angle of current has gradually decreased from initial value to zero. The method can always make the displacement angle less than thyristor's firing angle. So the voltage of the induction motor won't oscillate. Therefore, the oscillation of current, electromagnetic and speed can be eliminated during the soft-starting process of induction motor. This paper verifies the correctness of the method by simulation at first.

根据上述原因，本文提出了采用关断角控制的新型控制策略，这种控制策略是使电动机在起动过程中的电流关断角由某一初始值逐渐减小到零，利用该方法可以使感应电动机起动过程中的续流角始终小于晶闸管的触发角，这样续流角的变化就不会引起电动机端电压的振荡，因而就从根本上消除了感应电动机软起动过程中的振荡现象。

The results showed that over 500.0 μg/L of Jagged-1/Fc led to the obvious enhancement of the proportion of CD4+CD25+ T cells within the day 4 to 6 of induction, which was abrogated with an anti-Jagged-1/Fc monoclonal antibody. This induction action of Jagged-1/Fc on CD4+CD25+ T cells was also inhibited by the block of a Notch signal pathway with N-[N-(3,5-difluorophenacetyl)-L-alanyl]-S-phenylglycine t-butyl ester. The level of IL-4 and IL-10 in the supernatant of T cell culture and their intracellular level were elevated by the induction of Jagged-1/Fc,and the level of TGF-β1 in the supernatant was not altered.

结果显示，超过500.0 μg/L剂量的Jagged-1/Fc使CD4+CD25+ T细胞百分比明显增高，诱导时间需要4～6天，抗Jagged-1单抗能抵消Jagged-1/Fc的诱导作用，用DAPT阻断Notch信号通路的活化也能抑制Jagged-1/Fc的诱导作用，Jagged-1/Fc诱导分化的T细胞培养上清中IL-4和IL-10的水平明显增高，TGF-β1无明显变化，胞内IL-4，IL-10，IL-2和TNF-α的水平也呈增高趋势。
