The first functioning electronic computer was the ENIAC, which was booted up in 1945 to solve ballistic calculations for the U.S.

第一部功能电子计算机是电子数字积分计算机。1945年该机为解决美军弹道计算问题而启动。

The real-time solution for differential equations of exterior ballistic on antiaircraft artillery is an important research problem in fire-control domain.

高炮外弹道微分方程组的实时解算一直是火控领域中一项重点的研究课题。

Usually, we assume that exterior ballisticmeasuring error has normal distribution with zero mean. But during the real measuring,it is possible for exterior ballistic measuring parameters to cause system error.

通常假定外测误差服从零均值正态分布，而在实际测量中，外测参数有可能带有系统误差，它的存在对飞行轨道和落点信息的获取都具有不利的影响。

Investigation of the ballistic propagation of acoustic wave through two almost same sintered samples with face - centered cubic lattices indicates that there is a band gap range respectively in two order quasi - homogeneous media.

研究超声波经过两个烧结样品的行为。两个烧结样品为有序的面心立方结构，它们的结构几乎相同。研究表明：在两个有序的准均匀的介质中分别有一个禁带区域。

Magnetization curves of the polycrystalline Fe-Co and Ni-Co alloys of the cubic system and also of the pure cobalt were determined by means of a ballistic method. Gans' theory of the magnetic properties of isotropic ferromagnetics was applied. The agreement between his theory and the experimental results is quite good for the strong fields but not so for the weak fields, just as in the ease of the pure ferromagnetics.

用冲击法量属於正方晶系之铁钴及镍钴合金并纯钴之多结晶体之磁化曲线与Gans氏各向同性铁磁物质磁性之理论相较知在强磁场时理论与实验之契合甚佳在弱磁场时则较差，弱磁场时之差异，可以Gans氏计算时略去磁化各元晶体於其易磁化方向至饱和度所需之自由能一点解释之改正此点后理论与实验之契合大体改善在数种合金且极佳。
