The IGBT-controlled chopper circuit can be greatly simplified as the smoothing inductor and commutation circuit of the thyristor-controlled chopper circuit are no more required.

文中提出了以IGBT、二极管、电阻和电解电容等四个元器件组成的斩波电路，经实验和仿真证明不仅能有效地调节转子电阻，而且同时兼有IGBT关断吸收电路的作用，能显著改善IGBT的关断轨迹。

Geladaindong region were analyzed using the HYSPLIT-4 model, and microparticles in Mt.Geladaindong snow were mostly influenced by dust aerosols from the northwestern Tibetan Plateau, South Asia. Coarse particles may come from the local rocks near glaciers. Research of seasonality of microparticle in snow could provide the information on modern environment processes, and is the base of further interpretation of ice core records.

结合NCAR/NCEP再分析资料，应用HYSPLIT-4模式模拟的不同季节5 d后向气团轨迹图表明，各拉丹冬峰冰川区雪冰中不溶性微粒可能来源于中亚、南亚和青藏高原本身，其中影响最大的可能是青藏高原自身的沙尘源区，同时冰川区裸露基岩对雪冰中不溶微粒含量亦有贡献。

Based on velocity and direction distribution of mobility model, this text put forward the scheme of simulating the movement of mobile station and the methods of computing the sojourn time, then make statistical analysis on the sample to obtain the probability density function of the sojourn time and the probability of handover.

在移动模型运动速度和方向分布的基础上，利用Matlab模拟移动模型在小区内运动轨迹，并随时判断移动模型是否离开小区，以此计算移动模型在小区内的停留时间，并对多次计算所得到的大量数据进行统计，得出停留时间的概率分布，并推倒切换发生率。
