波点

The reflected wavefront arrives at the point X at time t=(2L-x)/C.

反射波前在 t＝2L－x／c。时到达X点。

To avoid nadir round-trip time and pulse sending time, blind zones present.

在星载条件下为避开星下点回波和发射脉冲窗口，会造成存在测绘带盲区。

In the same sense according to the ancient interpretation are explained the two pillars Boaz and Jachin; the Rosecroix (a cross with a rose in the centre); the point within the circle; the "vesica piscis", the well-known sign for the Saviour; the triple Tau; Sun and Moon; Hiram and Christ; the coffin; the Middle Chamber and even the Sancta Sanctorum, as adyta or most holy parts of each temple, usually contained hideous objects of phallic worship.

在同一意义上根据古代解释解释的两大支柱波阿斯和Jachin ；的Rosecroix ；点的圆圈内的"阳南鱼"，众所周知签署的救世主；三头；太阳和月亮；西贡和基督；棺材；中东厅，甚至圣Sanctorum ，作为adyta或最神圣的地方的每一个寺庙，通常载骇人听闻的物体的阳具崇拜。

By using cross-iteration technique and the Schauder fixed point theorem, the existence theorem of travelling wave solutions of this system is established.

针对反应项的不同单调性，引进交互迭代格式，利用Schauder不动点定理建立了行波解的存在性定理，并将所得结论应用到时滞竞争系统。

Looking closer, I see that a scrubbing brush is called for: yesterday, I failed to deal adequately with Sam's Jackson Pollock moment with the poster paints.

凑近点看，我还得找个地板刷：昨天Sam像杰克逊·波洛克（Jackson Pollock，美国艺术家---译者注）那样把颜料甩来甩去，我还没有把它全部清理干净。

To this end the original 'Blue Fox' radar is replaced by Ferranti 'Blue Vixen' coherent pulse-Doppler track-while-scan radar to improve acquisition and look-down capabilities, and other improvements are a MIL 1553B digital databus (making it possible to carry Sea Eagle anti-ship and ALARM anti-radar missiles) and the installation of the Marconi Sky Guardian 200 RWR, the JTIDS for secure voice and data links, two additional underwing hardpoints, wing tip stations for two AIM-9 Sidewinder short-range AAMs, wing improvements, a revised cockpit with HOTAS controls, larger drop tanks, provision for 25 mm Aden 25 cannon in place of the elderly 30 mm weapons, and possibly a Plessey missile-approach warning system.

为实现这一目的，原有的"蓝狐"雷达被新型的"蓝雌狐"连续波脉冲多普勒雷达替换，该雷达具有搜索的同时锁定目标的能力，可下视下射。其他改进包括加装军用1553B数据链，这使得MK2可以使用"海鹰"反舰导弹和ALARM反雷达导弹。另外加装了马可尼"天空哨兵200"通信系统，JTIDS保密语音及数据链路。增加了两个翼下外挂点，翼尖挂架可携带两枚AIM-9"响尾蛇"近距空空导弹。细节的改进还包括：机翼设计有所改进；改进的座舱设计；更大的副油箱；采用阿登25mm机关炮代替了以往的30mm机炮；可能加装了导弹告警系统。

In this dissertation, high-speed CCD camera was used as the image system. An eight-wave retardation plate was added within the optical path to remove the phase shifting device. By means of short exposure time and precise time sequency control, transient information in a series of time scales could be obtained successfully.

本研究承续前人的努力采用高速CCD为取像系统，但改於光路中加入八分之一波板於光路中来取代传统的相移机构，再藉由极短的曝光时间和时序控制成功取得了振动物体一系列连续时间点之暂态资讯。

At 0950 on 30 Jun, Moscow ordered Sevastopol to be evacuated.

6月30日早上9点50分，莫斯科下令塞瓦斯托波尔的苏军撤退。

With the help of the multi-resolution analysis, the singular part in the vibrational signal is abstracted to distinguish the periodic signal, so the useful information for fault diagnosis is got.

将小波分析技术应用到车辆变速箱的奇异点检测中，通过多分辨率分析提取振动信号中的奇异信号，将其周期信号分开，为故障诊断提供了有用的信息。

According to this work, the two-dimensional field distribution of continuous sinusoidal wave vertically or obliquely radiated by a linear array of five monopole sound sources is numerically simulated in terms of the different initial acoustic pressure .

在此基础上，数值模拟了初始声压强弱不同的5个点声源组成的线阵列垂直或斜向辐射的连续正弦波在大气中传播时二维声场的分布情况。

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%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
