There are generally three types of Ge-profile in base:triangle-profile,trapezium-profile and rectangle-profile.
本文就基区中Ge组分分布的三种形式:三角形、梯形、矩形进行计算机模拟并对结果进行讨论,发现其他条件相同时,梯形分布的pnp SiGe HBT的放大系数最大,而且梯形和三角形随Ge组分的增大而增大,但是矩形分布在Ge组分增大到一定数值后开始减小,而特征频率情况类似。
The calculating method of additional stress in soil under trapezoid distributed load;
梯形分布荷载下地基附加应力计算方法
