The paper discusses the usefulness of the combined environmental test to air defense missile's reliability growth, the methods to define the test sections and environmental stresses and judge the faults, the methods to terminate tests ,and so on.

本文论述了综合环境试验对防空导弹可靠性增长的作用、试验剖面与环境应力的确定、试验中故障判决方法和试验结束方式等一系列试验中遇到的问题，并进行了探讨。

One of the most interesting conversions based on T-34/76 (model 1943) chassis was 2cm Flakvierling auf Fahrgestell T-34, an anti-aircraft tank - Flakpanzer. Also known as Flakpanzer T-34, it was armed with 20mm Flakvierling 38, which was a four barreled 20mm anti-aircraft L/115 gun.

被德军缴获的T-34/76 经过改造后被命名为：Panzerkampfwagen T-34 747 型，从1941年晚些时候起，缴获的T-34通常被送往里加的工厂进行修理和改进）其中最有趣的要数根据T-34/76 (1943型)为底盘设计的一款防空坦克--Flakpanzer。
