In view of the short duration in the test of a fuze's self-destruction time,we discussed the possible factors such as fuze structure and processing quality,the angle of fire,weather and barrel conditions.Meanwhile,we used the method of variance analysis to process significance test for different barrel conditions on the malfunctioning of fuze self-destruction.After eliminating some other possibilities,we retrieved the fired shell which has abnormal band with fin,and finally found the real cause of the problem mentioned above.

由一带离心自毁机构引信自毁时间出现偏短的试验结果出发，从引信结构参数和加工质量、射角、气象条件、身管状态等方面入手，着重用方差分析法对身管状态进行显著性检验，探讨引起引信自毁时间异常的因素，在逐一排除了其他因素后，通过射击回收的方法发现弹带有异常飞边，找出了问题的原因。

Finally, according to the characteristics of wind loads on the roof, an aerodynamic solution to minimize the peak suctions by venting the leading edges and the corners of the roof is recommended.

A two cell SBS phase conjugating mirror pumped by pulsed Nd∶YAG laser was experimentally investigated. After returned to YAG amplifer and coupled out by a polariser, SBS output beam had the characteristics of duration tunability and good quality with near diffraction limited far field divergence angle.

对脉冲Nd：YAG激光器抽运的双池受激布里渊散射相位共轭镜进行了实验研究，将相位共轭镜后向反射光束馈入YAG放大级，经放大级放大，由偏振片耦合输出的激光束具有高质量、脉宽可调的特点，远场发散角接近1倍衍射极限。

A 3D corner reflector antenna, with dimensions of 1.7 wavelengths, still has too narrow a vertical diagram and is suitable only for very shallow offset parabolas, with F/D of about 1 and more.

一个尺寸为1.7波长的3D角反射器天线，垂直方向图非常狭窄，只适合很浅的偏馈抛物面天线，其F/D大约1或者更多。

It is obvious that 3D corner reflector antenna could be also adjusted for offset parabolas with a lower F/D if the diagram could be widen in vertical plane and narrowed in horizontal plane so that they are approximately equal to each other and at the same time retain all other good characteristics of this antenna.

显然，3D角反射器天线也必须调整才能用于低F/D的偏馈抛物面，如果它的垂直方向图必须宽，水平方向图必须窄，那么垂直和水平两者之间必须大体平衡，而同时要保持天线的其它所有良好特性。

The attitude control system is compared with a micro momentum-biased reaction wheel and three-axis magnetic-coil, to realize the followingfunctions:(1) after release from launcher, by B control law, this mode can damp the body rate down;(2) After that ADCS switches to the three-axis-stabilizing mode.

姿态控制子系统，以俯仰偏置动量轮组合三轴磁力矩器构成控制系统主体，实现初始入轨后的姿态角速率磁控阻尼，以及姿态的三轴稳定控制；分别对动量轮和三轴磁力矩器进行了参数设计。

Based on the conversion from GPS coordinate system to the west-north-up inertial coordinate system,the west-facing mobile yaw angle was calculated ,and finally, the unity of coordinate systems was completed.

该方法在由GPS坐标系转换到西北天惯性坐标系的基础上，计算与西向的游移偏航角，最终完成坐标系的统一。

We have one other pond just like this, White Pond, in Nine Acre Corner, about two and a half miles westerly; but, though I am acquainted with most of the ponds within a dozen miles of this centre I do not know a third of this pure and well-like character.

我们还有另一个这样的湖，在九亩角那里的白湖，在偏西两英里半之处；可是以这里为中心的十二英里半径的圆周之内，虽然还有许多的湖沼是我熟悉的，我却找不出第三个湖有这样的纯洁得如同井水的特性。

In order to solve the problem, in this dissertation, a new IA technology based on wavelet-filtering and two-position alignment is proposed. The useful signals of sensors are gained by wavelet filtering; the error angles, constant drifts of FOGs and biases of accelerometers are computed through signals at two positions.

对此，本文提出了一种基于小波滤波方法和二位置对准方法相结合的初始对准技术，采用小波滤波方法提取传感器的有用信号，利用两次转位的信号解算初始对准的误差角、陀螺的常值漂移和加速度计的零偏。

Meanwhile, the reliability and validity of the model with consideration of tire nonlinearity, lateral mass transfer and axis slip are verified by the steady static circular test and steering wheel angle step input test using a Unique (NJ1020) car.
