查询词典 echo

This way, the pilot could home in on his target by matching the sizes of echo pulses from the two antennas, sort of like "lobing" described earlier in this article. When the two echoes were equal, the plane was headed directly at its target.

这样飞行员便可通过比较两天线的回迹来导向他的目标，如同前面介绍过的&波瓣法&，当两回迹大小相等时，目标就在前面。

For precision azimuth, as in gunfire control, a double-lobe pattern (figure 3) can give great directional precision by finding the direction in which the echo "pips" for both lobes are of equal heights. This is called "lobing".

当需要精确的方位角，如指挥火炮时采用双波瓣发射，两波瓣回迹强度相等时便可获得精确的目标方位角，这被成为&波瓣法&。

All cases of X-ray signs included small node 8 cases,mass with spiculate border and lobulate margins 20 cases,cluster microcalcification 26 cases,structure tortuosity disorder 10 cases,small laminated density markup 7 cases,the partial blood vessel increases thickly 3 cases,4 cases with normal digital mammography which were done by color ultra promptly,low echo tubercle were confirmed for breast cancer by instrument.

其中8例呈小结节影，20例呈肿块伴有毛刺样改变或呈分叶状，26例仅有成簇细小点状钙化，10例局部结构扭曲紊乱，7例局限性小片状密度增高，3例表现为局部血管增多增粗，4例患者彩超提示低回声结节，数字钼靶未发现明显病变，经穿刺活检证实为乳腺癌。

This boxed set containing all 28 episodes from the first two seasons is payback for the show's devoted cult following, who may be moved to echo the words of infant Stewie Griffin, the megalomaniacal 1-year-old bent on matricide and world domination: Victory is mine!

&这装箱集包含了所有28集的前两个赛季是回收期为节目的专门邪教以下，谁可能被移动到回声的话婴儿 Stewie格里芬的狂人1岁执意弑母和主宰世界：&胜利是我的！

The students experiences echo those found in previous studies relating to the socialization of student nurses and emotional labour (Melia, 1987. Learning and Working. The Occupational Socialization Nurses. Tavistock Publishers, London; Smith, 1992. The Emotional Labour of Nursing. Macmillan, London).

学生的体验回应了以往关于学生护士社会化和情感疲劳的研究结果（Melia， 1987，学习与工作，职业化的社会化护士，Tavistock Publishers， London； Smith， 1992；护士的情感疲劳，Macmillan， London）。

The microphysical mechanism is different in the development of meso-γscale echo.

实测雷达回波的主要特点已由数值模拟所成功地复制。

That is why the Funeral Speech, written of a small provincial city in the untried youth of the world, will always find an echo whenever men and nations are living true to themselves, whether in the trenches of Mukden or in the cemetery of Gettysburg.

这就是在人类质朴无华的童年时代以一个地方小城市为题材的葬礼演说辞何以总能在按自己本色生活的人们和民族中引发共鸣，无论是在奉天的战壕中，还是在葛底斯堡的公墓里。

Studies the high precision estimation methods of echo frequency, proposes a simplified TLS-ESPRIT method for frequency estimation based on uniform sampling data. For moving platform, such as torpedo, proposes a time fusion algorithm for target status estimation based on multicycle data of single sensor.

c。深入研究了回波信号的高精度频率估计技术，提出了一种基于均匀采样数据的TLS-ESPRIT频率估计算法；针对运动平台，提出了一种单传感器多测量周期目标状态估计的时间融合算法；以炸点预测为例构造了相应的状态模型及算法，计算机仿真验证了融合算法的有效性。
