导出了热扩散一步充气法和分步充气法充气时，薄壁玻璃微球壳的内压变化，及其在空气中的气体渗漏速率和保气半寿命的表达式，提出了确定分步充气过程操作参数的约束条件。Ｄ２气体通过薄壁玻璃微球壳的扩散速率与分步法充Ｄ２气体时其内压的实验测量值与计算值相符合。
The expression of internal pressure of thin-walled glass microsphere shell, gas leakage rate in air and half-life of gas-retaining is deduced when the thermal diffusion one-step inflation method and the step-by-step inflation method are inflated. Inflation process operating parameters of the constraints. The diffusion rate of D2 gas through the thin-walled glass microsphere shell agrees well with the experimentally measured values and calculated values of the internal pressure of D2 gas in the step-by-step method.
