Oppenheimer , on the other hand , was raised in an environment where his gifts were cultured , he was encouraged from a young age , and was given the best education possible .

针对一种基于二次电子发射的跳跃电子阴极三极管结构进行了研究，这种特殊结构可以有效地提高了电子注电流密度，并减小受残余气体离子的对阴极轰击造成的阴极发射跌落。

A hopping electron cathode triode structure based on secondary electron emission has been studied to improve current density of electron beam and reduce the cathode emission slump caused by ion bombardment of residual gases .

文中针对孤立小受端系统，通过仿真表明在大有功缺额扰动下此类系统极易出现低电压问题，从而很大程度上影响了频率行为，并影响了低频减载装置的动作。

Especially for the small isolated receiving power systems , simulation results have shown that such systems will suffer from voltage problems which will affect the frequency behavior and furthermore the action of UFLS utilities .
