The blood IgG and IgA level of new soldiers is significantly lower than that of control,But the IgM level is higher than that of control.Conclusion It suggest that old soldiers' paratroop stress is normal,the high stress can be lessen by training.

新兵在跳伞应激状态下免疫功能受抑制，但老兵免疫能力没有下降，某些免疫指标还有增高，表明老兵跳伞应激的反应是适度的，严重的跳伞应激可通过多次的训练而得以减轻。

A spectral line is emitted when an atom proceeds from an excited state to a lower state.

Its structure and property have not been understood clearly. Polyimide wear-out and breakdown can occur under long-term electric stressing due to many different reasons, making their insulating life ended. Wear-out and breakdown of polymers are closely related to the dissipation of electrostatic energy in space charge region.

聚合物的老化和击穿与空间电荷区域静电能的释放有关，电致发光代表材料中分子受激的化学活性强的状态，是能量耗散的方式之一，可作为材料预击穿及结构老化的先兆，是研究聚合物分子中的陷阱结构和它所控制的空间电荷的存贮和输运特性的重要实验手段。
