English Abstract	针对系统服务中的特权用户问题,提出一种面向服务进程的用户权限隔离模型,依据安全级别将用户、隔离域、程序模块进行映射关联,利用虚拟化技术为不同用户构造相互隔离的运行环境,形式化定义用户隔离域,给出虚拟化构建隔离域的关键技术及实现方法,从而实现用户权限的隔离,消除系统中潜在的特权用户。

Abstract	Blue InGaN/GaN multiple quantum well light-emitting diodes with the conventional and graded last barriers (GLB) are numerically investigated. When the last GaN barrier is replaced by a linearly graded InxGa 1 - xN barrier with increasing indium composition in the growth direction, the forward voltage is reduced from 3.60 V to 3.25 V, and the efficiency droop is improved from 36 to 13. Simulation results indicate that these improvements can be attributed to the formation of a deep potential well in the GLB which enhances the electron confinement and improves the hole injection efficiency. © 2011 American Institute of Physics.
