By using linear E f n s approximation, a new analytical charge control model of the double heterojunction double planar doped high electron mobility transistor ( HEMT) is deduced based on Poisson's equation. 利用泊松方程以及异质结能带理论,通过费米能级-二维电子气浓度的线性近似,推导了基于双异质结双平面掺杂的HEMT器件的电荷控制模型。
The Logarithm Linear Model of Inter-Generation Occupational Mobility 职业代际流动的对数线性模型
The problem can be formulated as a 0-1 integer linear programming with some restricted conditions, because that the handoff action for the terminal is restricted by the mobility and the number of wireless interfaces. 同时考虑到终端的移动性及无线接口数量对选网的限制,将切换问题描述为带多个限制条件的0-1整数规划问题。
The models comprehend various situations of Ad Hoc mobile terminals and are more practically comparing with the linear mobility model. They have the merits of large usage range, variable parameters. 该模型不同于一般的线性模型,充分考虑adhoc网络移动终端运动的各种情况综合设计而成,更符合实际情况。具有适用范围广、参数可调的特点。
At the same time, study the impact of the mobility factor, the use of multiple linear regression model, the impact of mobility on a variety of indicators have done a detailed analysis. 同时,在研究流动性的影响因素时,运用了多元线性回归模型,对影响流动性的各种指标做了细致的分析。
