| 摘 要： | 根据空心玻璃微球（HGM）耐内、外压能力与玻璃强度及形状因子的关系，用压力负荷分步增加的方法分别实验测量了直径为350μm～550μm、壁厚＜1.1μm的3种配方HGM的耐内、外压能力及HGM玻璃的杨氏模量和拉伸强度，并由强度测定值给出了不同直径与壁厚HGM的耐内、外压能力的计算式，分析了测量误差，提出了改进方案。 |

| Abstract: | A experimental method, Pressure Loading by Steps, is designed to measure the fracture and buckling failure pressures of hollow glass microspheres(HGM) for use in laser fusion experiments. The failure pressures of 3 kinds of HGM with out-diameters of 350m m～550m m and wall-thickness less than 1.1m m and their glass’s elastic moduli and tensile strengthes are measured experimentally. From the results, experimental formulae are obtained to evaluate the failure pressures of HGM in different out-diameter and wall-thickness without any test. Moreover, the experimental error sources and ways to improve them are discussed. |
