摘要
采用分步法对低强度空心玻璃微球充氘氚气体。为了充气 ,建立一套高压系统 ,在 1 5MPa下漏率为 3 .7× 1 0 -4 Pa L/s。用铀床和 La Ni5床组合 ,作为充气的高压气源。室温和2 50℃时 ,玻璃微球的最大承受压力为 1 .0 MPa,内外压之比约 0 .51。在 2 50℃时 ,充进微球内的氘氚气体量为 0 .51～ 0 .54MPa,满足了物理实验的要求。
Step by step fill procedures for thin wall hollow microsphere was applied. The leakage of the metal system was 3.7×10 -4 Pa L/s under the pressure of 15MPa. U and LaNi 5 combination serve as good gas resource,supplying high pressure. Both at the room temperature and 250℃, the shell can bear 1.0MPa and the pressure ratio of inside to outside was about 0.51. At 250℃,the pressure of D T filled into the spheres was 0.51～0.54MPa,which satisfied the physical experiment requirement. [WT5”HZ]
