The opening parachute signal is required to sent on the fixed height when the vehicle reentry.The height controlled error through axis apparent acceleration can not meet the required precision.

摘 要 弹道式飞行器再入时，常常要求在规定高度上发出开伞信号，过载延时控制方法误差太大，不能满足精度要求。

Sonja Gibbs: One of the a lot of important credibility is absolutely what you mentioned just now. Oil prices are absurd to circling out of control. Humans that anguish about all of this tragedy blame the US and the all-around abridgement into recession accomplish one actual big acceptance that oil prices will acceleration absolutely high. If that doesn't appear and if the axial banks accept been responding with lots of liquidity, amount cuts are advancing up, there's added acumen to be hopeful that the appulse will be abbreviate and the backlash would appear adequately soon.

索尼亚·吉布斯（野村投资银行首席战略员）：最重要的一点是刚才提到原油价格是不可能一直加剧上升的人们都担心这场悲剧会导致美国和全球的经济萧条，但这个推断的基础是建立在原油价格会暴涨的假设上的如果原油价格不发生暴涨，如果全球的中央银行都向市场大量注资，并下调利率，这样就有希望使这场事件造成的负面影响只存在很短的时间，而且经济就会迅速反弹。

With connected appearance up of celebrity faces in media, it's no admiration that we accept become absent with the way celebrities dress and eat. The appulse celebrities accept on the accessible has fabricated artist sunglasses acceleration in acceptance over the years.

宽松阔大同时富有动感的款式造型，大胆的鲜艳亮丽色系交错印花，奢侈大牌中少见的极度年轻化设计，小碎花、鲜艳色彩的大量运用让LV女孩张扬出更多年轻活力，皮草点缀出LV 奢华高档韵味，大热流苏元素穿插其中。

Based on the equation of the model, the acceleration, displacement and story shear of a seven- story building with a three-story appurtenant structure under three control systems including only rubber-bearing base, rubber-bearing and damper and no rubber-bearing are computed under the earthquake record of 1940 EI- Centrol, respectively.

根据控制系统方程，在无橡胶垫、仅设橡胶垫和同时布置橡胶垫和阻尼器的三种工况下，运用1940EI-Centrol加速度波，对具有三层裙房的七层建筑结构进行了分析，得到了七层建筑的加速度、位移和楼层剪力等参数。

The analytic solution of optimum low-thrust power transfer between arbitrary elliptical orbits using continuous constant acceleration is presented, based on the orbital elements selected.

研究航天器在小推力的作用下，椭圆轨道最优转移的一种解析解法。

Aiming at this problem, we have carried out an experiment on seepage properties for mudstone and argillaceous rock, showed the test result, and analyzed the reason why both the β-factor and the acceleration coefficient are negative. In addition, mistakes often made by some researchers about positive or negative signs before the non-Darcy β-factor were pointed out.

指出一些文献在引用Forchheimer关系时出现的非Darcy流β因子前正负号的错误，给出了非Darcy流β因子和加速度系数出现负值的泥岩和砂质泥岩试样全应力－应变过程中渗透特性试验结果，并对其原因进行了粗浅的分析。

By applying the difference arithmetic to solve the differential vibration model of the single-degree-of-freedom,the acceleration responses of the vibrated bevel wheel was calculated.The bevel wheel contact fault was simulated by taking it as the impulsion loading in local point.By using techniques of wavelet de-noising and demodulated resonance,gear contact character information was picked up successfully.

从齿轮的单自由度振动模型出发，运用差分算法对模型进行求解，得到斜齿轮的振动加速度响应，将齿面接触型故障等效为在局部点突加一个冲击载荷，对齿轮齿面接触型故障进行了仿真，利用小波降噪和共振解调技术分别对仿真的染噪振动加速度信号进行处理，成功地提取了轮齿接触故障的信息。
