This characteristic could be qualitatively explained as interference between σ amplitude and π amplitude of electrons final wavefunction. It also depends on the impact parameters: the π amplitude contribution is dominant at small impact parameters, which leads to a symmetric velocity distribution around the internuclear axis. However, At large impact parameters the σ amplitude contribution increases relatively, resulting into a asymmetric electrons velocity distribution around the internuclear axis.

出射电子的上述分布特征可由出射电子波函数σ振幅和π振幅的干涉进行定性解释，σ振幅和π振幅对出射电子波函数的贡献与碰撞参数相关，在小碰撞参数下，π振幅的贡献更加明显；而在大碰撞参数下，σ振幅的贡献更加显著。

The results of calibration of 4He in desorption system show that the correlation coefficient is more than 0.99 and the contribution of memory effect can be ignored. The contribution of ionized atom T(superscript +) for partial pressure of m/e=3 is very little and is determined according to I+≈0.01I(subscript T2)+, so the measurement of 3He can be done without interference of T(superscript +). The relationship between gases release rate and annealing temperature can be obtained after the data are smoothed and differentiated.

研究结果表明：四极质谱计标定解吸系统内4He的分压＜350 Pa时，其相关系数R＞0.99，且记忆效应的贡献极弱；离子态氚T对m/e=3组分分压的贡献可按I+≈0.01I(下标 T2)+确定，不干扰3He的测定；将气体解吸所得的积分数据经平滑并微分处理后可准确得到气体释放速率与退火温度的关系，即热解吸谱。

How old and how old contribution should be made to the country after saying to do his, saying high-sounding, sound very great, you want the thing that do only, parents of not let sb down is enough, accomplish this, go wanting how to answer a newspaper office to meet again, redound country, make contribution to the country.
