First, ringing can drive voltage and current waveforms outside the forward biased and reverse biased safe operating areas of the power switches causing device reliability degradation or near instant failure of the power semiconductors and other components.

LCL-816G 传感器模型是由四个电阻元件组成的桥，需电压激励。将5V 激励电压加在传感器高端，施加900g 最大激励时，满刻度输出摆幅为±10mV 差分信号。该小差分信号被双运放仪表放大器放大。根据电路精度要求，选择一个12位 A/D 转换器。

TUNEL method was used to detected the apoptosis in the artery. Results:①The MSC cocultured with VSMC expressed smooth muscle a-actin, calponin and CD31, no cells positive for calponin and CD31 were detected in the control group; and a lot of filaments were observed in the co-cultured MSC by electron microscopy.②We gain dual-stable expression of AT2R gene medicated by doxycycline regulatable system of mesenchymal stem cells.

单独培养及VSMC条件培养液培养的MSC仅SM-α-actin表达阳性；(2)Dox-on系统由四个质粒组成：调节质粒pUHD17-1 hyg，荧光报告质粒pUHC 13-3，筛选质粒pSV2neo以及含目的基因AT2R的应答质粒pUHD10-3/AT2R，以上质粒经鉴定均与其背景资料相符合，可用于实现目的基因片段在靶细胞中可调控表达研究；(3)本实验通过连续两个回合的转染及抗生素压力筛选，经Dox诱导表达后获取出低背景、高诱导表达AT2R基因的克隆。
