And introduces the structure and operational principle of QLZ87AGL made in china which has been armed by our army. Based on the classical interior ballistics and weapon gas dynamics theory, a mathematics model of the interior ballistics and gas system is established.

运用经典内弹道、武器气体动力学和自动武器系统动力学理论建立了榴弹发射器在发射过程中的内弹道、后效期、导气装置的气体动力学模型和机构二自由度的动力学模型。

In this case, dust of the same size can levitate at two different positions in the cathode.

另外还发现：在考虑极板有强电子束发射和尘埃粒子本身的二次电子发射时，同一大小的尘埃粒子能够悬浮在鞘层中两个不同的位置。

In that case a time limit of three (3) minutes per target will be allowed from the time the athlete takes his position at the shooting peg, which he must do as soon as possible after the shooting position becomes available

在上述的个案中，每一靶位3分钟的限时系允许选手站在他的发射位置后计算；同时他也必须在发射后尽快开

"By 1965 they had been replaced by the much larger Titan II, which could be launched directly from its silo. With a nine-megaton warhead, Titan II was the principal weapon in the land-based U.S. nuclear arsenal until the 1980s, when it was replaced by solid-fueled ICBMs (e.g., Minuteman missiles)."

在1965年由更大型的泰坦2号取代，此型可由发射井直接发射，带有九百万吨级弹头，一直是美国陆基核武的主要武器，到80年代被更精确的固体燃料洲际弹道飞弹取代。

Transmit diversity is a hotspot in MIMO research. In fading channels, the relation of open loop transmit diversity and close loop transmit diversity and their performance contrast has not been studied.

发射分集是多天线MIMO系统的研究热点，在衰落信道中开环和闭环发射分集的关系，不同信道状态条件下的性能对比还缺乏深入研究。

H-BN thin films were prepared on the (100)-oriented surface of n-Si by r. f. sputtering physical vapor deposition. The field emission characteristics of the BN films were measured in a ultra high vacuum system. It has been found that the field emission characteristics of BN films is affected evidently by substrates temperature.

利用射频磁控溅射方法，真空室中充入高纯N2(99.99%)和高纯Ar(99.99%)的混合气体，在n型(100)Si基底上沈积了六角氮化硼薄膜，在超高真空0^(-7Pa系统中测量了BN薄膜的场发射特性，发现沈积时基底温度对BN薄膜的场发射特性有很大影响。

Vessels of Runabout size or above are fitted with more than one emitter - large starships having enough to ensure all-round coverage.

小型星舰或较大的星舰一般都配备一具或更多具的发射器，另外大型星舰都拥有能够全方位发射牵引光束的能力。

5 And 1. 2-1. 3 respectively. The results showed that the graphite like carbon film had higher work function and lower secondary electron emission coefficient than those of DLC film.

总的来说，两者均具有较大的逸出功及较小的二次电子发射系数，后者的逸出功大于前者、二次电子发射系数小于前者。

Taking into account the conjugate heat transfer between electrolyte and torpedo shell as well as between torpedo shell and sea water inside the tube, the time histories of the electrolyte temperature and the temperature contour on torpedo shell and tube were obtained.

考虑了电解液与鱼雷壳体、鱼雷壳体与发射管内海水的对流耦合换热，得到了电解液的温度变化规律以及鱼雷壳体和发射管体上的温度分布规律。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
