Construction of Larger Area Density-Uniform Plasma with Collisional Inductively Coupled Plasma Cells

The plasma density and electron temperature of a multi-source plasma system composed of several collisional inductively coupled plasma （ICP） cells were measured by a doubleprobe. The discharges of the ICP cells were shown to be independent of each other. Furthermore, the total plasma density at simultaneous multi-cell discharge was observed to be approximately equal to the summation of the plasma density when the cells discharge separately. Based on the linear summation phenomenon, it was shown that a larger area plasma with a uniform density and temperature profile could be constructed with multi-collisional ICP cells.     

耐高温改性双马来酰亚胺玻璃布层压板的研制

以改性双马来酰亚胺树脂为胶粘剂 ,浸渍制备相应的玻璃布预浸料 ,并采用热压工艺制得耐高温改性双马来酰亚胺玻璃布层压板。用TGA方法研究了基体树脂的热稳定性 ,通过热重点斜法 (TPS)评定了该层压板的耐热等级。实验结果表明 ,该基体树脂溶液粘度低 ,室温下的贮存稳定性好 ,于浸料使用期长 ,制得的层压板具有优良的机械电气性能 ,能在 1 90℃长期使用。
