STOCHASTIC CURRENT DRIVEN BY A WAVE Simulation investigation of the effect of IBW on LHCD

离子伯恩斯坦波对低杂波驱动电流影响的研究

Ideal body weight ( IBW 1) was produced from China Adult Constitute Standard Guide.

根据《中国成年人体质测定标准指南》，查出相应年龄身高段病人的健康时理想体重（IBW1）。

The experiments show that large edge ion density fluctuation will make it difficult to excite IBW, the ranges of discharge parameters for optimally exciting IBW are consistent with those for normal operation of KT-5B tokamak.

实验表明，边缘离子密度涨落过大，将使离子伯恩斯坦波激发变得困难；正常的托卡马克运行的放电参数范围与有效激发离子伯恩斯坦波的参数范围一致；
