The effects of the content of Hexogen and Nitroguanidine on the combustion behavior of nitramine propel-lants under low pressure were studied in the closed bomb. The combustion data of six kind of nitramine propellants with different ratio of RDX/NGu were obtained from 20MPa to 60MPa by the closed bomb test.

为了研究RDX和硝基胍对硝胺发射药在低压下燃烧性能的影响，对六种RDX/NGu配比不同的硝胺发射药进行低压密闭爆发器静态燃烧实验，获得了在20~60MPa压力范围内硝胺发射药的燃烧试验数据。

Polarization curve and constant potential polarization experiments showed that AE events rate is linear to polarization current density.

极化曲线和不同恒电位下极化的声发射测量显示，声发射事件率与极化电流密度近似成线性关系，说明无论是阳极溶解还是铝合金的阴极腐蚀都是重要的声发射源。

The acoustic emission inspection and location principle of large vertical normal pressure storage tank bottom on-line inspection was studied.

基于大型常压立式金属储罐底板在线声发射检测及定位的原理，针对声发射检测过程中因声源性质不明确导致的罐底完整性评价结果不准确的问题，采用小波分析方法对罐底声发射信号进行了分解。

The results show that the penetrability of powder loads can be improved when suitably reducing bulk density and grain size of gun propellant, increasing nitrogen content of NC and choosing oblate spheroid explosive respectively under the constant test con

结果表明，在其它试验条件不变的条件下，适当降低发射药堆积密度、适当提高发射药中硝化棉含氮量、选用恒面燃烧的扁型药、降低发射药粒度均有利于提高射钉的穿透能力。

Here, we propose two kinds of OTD schemes: OTD-S and OTD-IM for MC-CDMA system, in which multiple orthogonal spread codes are used to build multiple orthogonal space transmission channels.

正交发射分集是CDMA系统一种简单有效的发射分集方法，本文提出了MC-CDMA系统的正交发射分集方法和对应的2种结构：OTD-S和OTD-IM。

The system can obtain the real-time image of the monitored scene. By image detection of the moving object, the wireless image transmission device can give off alarm signals when moving objects enter the scene. Then alarm signals and real-time image are transmitted through wireless receival station into the monitoring room for inspection.

该系统可以获取被监控现场的实时图像，对图像中运动物体检测，当有运动物体进入监视现场时，无线图像发射装置给出报警信号，并将报警信号以及实时的图像画面通过无线图像发射装置发射出去，通过无线接收基站传入监控机房，监控人员可以在监视器上观察报警现场的情况。

During operation in the space station, astronauts replace equipment and materials can be added or manned spacecraft from the spaceshuttle transport, supplies of equipment can also be the delivery of unmanned spacecraft.The former Soviet Union in 1971 launched the world's first space station ---"salute" on the 1st, then again in 1983 to launch a "salute" No. 2-7. The former Soviet Union in 1986 launched the space station more "Peace".

在太空站运行期间，宇航员的替换和物资设备的补充可以由载人飞船或航天飞机运送，物资设备也可由无人航天器运送。1971年前苏联发射了世界上第一个太空站———"礼炮"1号，此后到1983年又发射了"礼炮"2—7号。1986年前苏联又发射了更大的太空站"和平"号。

The effects of the content of Hexogenand Nitroguanidine on the combustion behavior of nitramine propellant s under low pressure were studied in the closed bomb.

为了研究RDX和硝基胍对硝胺发射药在低压下燃烧性能的影响，对六种RDX/NGu配比不同的硝胺发射药进行低压密闭爆发器静态燃烧实验，获得了在20~60MPa压力范围内硝胺发射药的燃烧试验数据。

5 At all targets, one shooting peg or mark for each division will be placed in such a way as to allow at least two athletes to shoot at the same time from either side of the shooting peg.

9.1.1.5在所有箭靶上，每一个组别的一个发射标桩或记号的设置，允许同组两名运动员同时从发射标桩的任意一边发射。

There are mainly two paths of computer information leakage, one is that the information being processed will be emitted into the air through the electromagnetic waves produced from the inside of computers, which is called radiated emission; the other is that such electromagnetic waves that contain information can also be transmitted and radiated through conductors such as power wire, signal line, earth wire, etc., which is called conducted emission.

计算机信息泄漏，主要有两种途径：一是被处理的信息会通过计算机内部产生的电磁波向空中发射，称为辐射发射；二是这中含有信息的电磁波也可以经电源线，信号线，地线等导体传送和辐射出去，称为传导发射。

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%.
