查询词典 propagation of errors

Salvoes of a group of artillery are the most used striking means in the battlefield. Many factors, such as the dynamic characteristics and random disturbance, can raise the positioning errors and synchronization errors, which will inevitably reduce the positioning accuracy of artillery.

火炮群射击是火炮主要的作战手段，由于各火炮特性的分散及随机干扰等多种因素的影响，在射击时会产生火炮与火炮之间的运动位置误差，出现运动不同步的现象，进而影响火炮的定位精度。

While the delay measurement methods currently used have poor precision, for there exist clock errors and location errors.

目前的时延测量方法由于存在时钟误差和位置误差因而精度较差。

No known system of Gnosticism corresponds with the errors mentioned in the Pastorals; in reply to this, however, it is said that the "errors are not given in detail to avoid undue anachronisms" ibid.

From the surfaces obtained and the assembly errors mentioned before, the geometry model of the worm gearing in which the typical errors are included is thus established for finite element analysis.

从表面获得的装配误差说过，几何模型的蜗杆其中典型的错误都包括在内因此建立有限元分析。

Moreover, blobs may move too close to the boundary because of advection errors or other numerical errors. It may cause serious fluctuations in evaluating the strength of the vortex sheet. In order to reduce the fluctuations, these near-wall blobs are also manipulated in use of the concept of "residual vorticity". Finally, we apply the so-developed solver to a simulation of the flow past an impulsively started circular cylinder at different Reynolds numbers.

此外既有涡泡也可能因对流或其他数值误差造成过於靠近边界，因此我们也设计一专门处理过於靠近边界涡泡之方法，以其他计算元素取代这些涡泡，降低进入物体内部之环量，进而降低涡片强度计算上的扰动。

Chirp scaling algorithm is considered more efficient and widely applicable when the bistatic SAR system is in side-look or small squint angle mode,but in large squint angle case,the errors caused by Taylor expansion are so large that the algorithm could lose its precision.In such a case,an equivalent mono-static SAR range mode which has fewer errors than Taylor expansion with large squint angle is proposed to substitute the range history of bistatic SAR.Then bistatic SAR images with large squint angles are gotten by common Nonlinear CS algorithm.The effectivity of the method is verified by Matlab simulation.

在正侧视或小斜视情况下，CS算法具有较好的聚焦性能和广泛的适用性，但在斜视角较大的情况下，该算法将散焦而不能成像，因而提出了用等效的单基地距离模型来代替双基地距离历史的方法，解决了大斜视角情况下距离模型二阶近似误差较大的问题，并结合单基地非线性CS算法，实现了在大斜视角情况下的基于GPS反射信号的双基地SAR高精度成像，最后通过Matlab仿真进行了验证。

摘 要：建立了基于gps的顺轨sar系统模型，通过将gps信号等效为chirp信号，研究了在该模式下的大斜视角chirp scaling算法。在正侧视或小斜视情况下，cs算法具有较好的聚焦性能和广泛的适用性，但在斜视角较大的情况下，该算法将散焦而不能成像，因而提出了用等效的单基地距离模型来代替双基地距离历史的方法，解决了大斜视角情况下距离模型二阶近似误差较大的问题，并结合单基地非线性cs算法，实现了在大斜视角情况下的基于gps反射信号的双基地sar高精度成像，最后通过matlab仿真进行了验证。

CTX ip 0.06 mg/kg, 0.12mg/kg significantly reduced the errors of the mice in Y-Maze test, decreased the mices training times, shorten the escape latency in Shuttle box test. In Step-down test, CTX ip 0.06mg/kg, 0.12mg/kg increased the escape latency and reduced the number of errors, CTX also reduced the searching platform latency and swim path-length in Morris water maze test with mice.

实验发现，CTX能明显增加热刺激引起的疼痛闭值，明显减少醋酸引起的扭体次数，并能显著增加小鼠在Y型迷宫实验中的正确反应次数，减少在穿梭箱实验中小鼠重新训练至学会标准的训练次数及小鼠的反应时间，能增加小鼠在跳台法中的潜伏期，减少错误反应次数，减少小鼠在Morris水迷宫实验中的寻台时间和游泳路程，以上效果均表现出明显的剂量依赖性。

There had been a moment during the breakfast meeting, though, after the backslapping and the small talk and when all of us were seated, with Vice President Cheney eating his eggs Benedict impassively and Karl Rove at the far end of the table discreetly checking his BlackBerry, that I witnessed a different side of the man.

那次早餐会期间，在表示过关心和寒暄以后，我们所有人坐了下来，我注意观察了一下，副总统切尼面无表情地吃着班尼迪克蛋（Eggs benedict，源自美国，以英式松饼、火腿、水煮蛋以及荷兰酱组合而成），卡尔。罗夫在餐桌的远端谨慎地经常查看他的黑莓手机，我目睹了他所不为人知的一面。
