小口径的

In this paper,basis on mechanical structure of certain minor caliber multiple launch rocket system and tactical demand of air defense and antimissile,it is analyzed in detail that friction torque, unbalanced moment ,impact moment of burning gas flow and variable rule of moment of inertia,which provide the foundation for more research of position servo system of multiple launch rocket system.

文中依据某小口径多管火箭炮机械结构及防空反导的战术要求，对影响多管火箭炮位置伺服系统性能的摩擦力矩、不平衡力矩、燃气流冲击力矩以及转动惯量的变化规律等进行了详细的分析，为多管火箭炮位置伺服系统的进一步研究提供了依据和基础。

The constant search for a more effective infantry weapon led in the 1990s to the concept of small-calibre high-explosive fragmentation grenade shells designed to burst over the heads of their targets, thereby permitting the attack of troops in defilade, ie hiding behind cover.

源于上世纪八十年代的对更加有效的步兵武器的不断研究得出了小口径高爆破片手榴弹的外壳设计用于杀伤目标头部的概念，从而形成了对隐藏于工事及掩体的部队进行攻击的手段。

Our plant specializes in producing drain valve and small-bore forging steel valve with long-standing history,advanced technology,comprehensive inspection technology and standardized quality control.

本厂是专业生产疏水阀和小口径锻钢阀门的厂家，具有悠久的历史，先进的工艺、完善的检测技术、规范化的质量管理。

Consideration of microstructure, the metal material has a face-centered cubic lattice of the austenitic steel, Reducing Valves copper and aluminum do not appear in the low temperature low temperature brittleness, but the hardness of aluminum and aluminum alloys is not high, the sealing surface of the wear-resistant aluminum , anti-scratch performance is poor, so the use of low-temperature valves have certain limitations, only used in low voltage and small-caliber valve.

从金相考虑，金属材料中具有面心立方晶格的奥氏体钢、铜和铝在低温状态下不会出现低温脆性，但因铝及铝合金的硬度不高，铝密封面的耐磨、耐擦伤性能差，所以在低温阀门中的使用有一定的限制，仅用于低压和小口径阀门中。

In addition, the Yancheng factory production and export of valves also increasing, from the original 23 have now developed into large-scale export-oriented enterprises more than 50, foreign sales in recent years it has an annual 40%~ 50% of the rate of growth, products sold in Europe, America, Southeast Asia, the Middle East and other countries and regions, exports of products from the past, small-caliber valve, gate valve gradual transition to a low-end products such as large-caliber valve, ball valve and other high value-added products.

此外，盐城生产出口阀门的厂家也日益增多，已从当初的两三家发展到现在拥有颇具规模的外销型企业50多家，外销量近几年更以每年40%~50%的幅度增长，产品畅销欧、美、东南亚、中东等国家和地区，出口产品从以往的小口径阀、闸阀等低档产品逐渐过渡到大口径阀、球阀等附加值较高的产品。

To counter the characteristics of forming the pressure wave in the highly dense small-grain propellant bed in a small- caliber gun, this paper establishes the interior ballistic multi-region homogeneous phase flow model.

本文针对小口径火炮小颗粒高密实装药床压力波形成的特有现象，建立了一种分区的内弹道均相流数学物理模型，模型的数值计算结果与实验有非常好的一致性。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
