1.This Paper describes the calculating formula of integrated flux of NTD,Con- figuration of irradiation device,and instruments of thermal neutron flux and temperature measurements. The decontamination of radioactivity and annealing treatment are also described. Finally,the doping accuracy,heterogeneous de- grees of axial and radial resistivity,life of minority carrier,and products rate of Kp200A SCR are introduced.
本文介绍了高通量堆中子嬗变掺杂所用的热中子积分通量计算公式、辐照置的结构、自给能热中子通量监测和温度测量装置,描述了出堆后单晶硅的放射性去污和退火处理,并对掺杂的精度、轴向和径向电阻率不均匀度、少数载流子寿命以及由此制作的 KP200A 晶闸管的成品率作了介绍。收藏指正
2.This method that more voltage vector chosen in per controlling period is integrated to target voltage vector according to torque, flux and speed increase number of voltage vector of system and apply more simple modulation method.
即根据转矩、磁链误差和速度的不同,在每个控制周期内选取多个电压矢量来合成目标电压矢量,增加电压矢量的数目,并采用更为简单的调制方法进行脉宽调制,从而大大降低转矩、电流和磁链的波动,使系统在低速时的转矩更平稳、性能更佳。收藏指正
3.The test device has a relatively high flux in 26.7-33.4 L/m~2·h in stable operation (average 30.3 L/m~2·h), far higher than the integrated or seperated MBR.
在装置稳定运行期间,保持了较高的膜通量26.7~33.4L/m~2·h(平均为30.3L/m~2·h),远远高于现有的一体式和分体式同类MBR,进一步表明新工艺可以有效控制膜污染。收藏指正
