Based on results of fire tests on heavy and small calibre guns, It has been found that

本文在对大、小口径火炮跳角试验数据整理分析的基础上发现:同一发弹,按传统跳角定义皮其测试方法所得的跳角值随靶距不同而变化很大,且同一发弹在不同距离上的最大最小跳角差|Δγ|与起始章动幅值成正比。本文对产生此现象的原因作了解释和分析。为纠正传统跳角定义上的缺陷而提出新的跳角定义为:射前炮(枪)身轴线与射后弹道起始段螺线弹道轴线间的夹角。

Oxygen Index, Smoke Density and Char Length of APP treated Pinus massoniana were measured before and after aging. The relation between impregnating level of fire retardant and non-combustion areas was described in this paper. Fire retardancy of APP treated wood meets Class Ⅰ according to JIS D 1201-77 and JIS A 1322-75. Fire test of formulated small wood house was compared with untreated small wood house. The result showed that APP treated wood can be used for interior room.

选用以聚磷酸铵为主剂的三种阻燃浸渍剂进行了椴木单板浸渍量与未燃面积的关系、马尾松处理材的氧指数、发烟等级、炭化长度以及模拟木板房屋点燃等阻燃性能的测定。每立方米马尾松木材对配方一、二、三的吸收量分别为32、30、25公斤时,可达JIS D1201-77难燃一级和JIS D1322-75抗燃一级标准、三个配方的阻燃效果按配方一、二、三的顺序提高。用配方一、二、三处理的木材可在室内常规温度、湿度条件下使用。

According to the statistical principle,this article puts forwardsolution to increase fire density on each course,which could not only cut down thtest cost but also ensure the reliability of the test results.The posibility to realizethe proposal is proved here therotically.This proposal throws convention to the wi-nds of the Soviet Union's fire range test method,which could save effective coursesfrom 4/5 to 2/3 for the fire test of Air Defense Artillery Complex System.Conseq-uently,the benefit is obviously....

本文根据统计学原理,提出了在每个航路上增加射击密度的设想,以达到既降低试验成本又保证试验结果的可靠性。文中对实现这种设想的可能性作了理论上的证明。这一设想突破了苏联靶场试验法的旧框框,可以使高炮综合体系统射击试验节省有效航次五分之四到三分之二,其效益是十分明显的。
