查询词典 diffract

In the course of the impulse through underground mediator, because the physical property and the geometric property of mediator is non-uniform, wave form and wave amplitude will change very much and the impulse after shock、antenna direction figure、the couple degree of ground surface、system interfere、non-uniform of the underground mediator、reflection surface's rough cause the disturb of radiation scatter and diffract will complex the figure .

脉冲在通过地下介质的过程中，由于介质的物性和几何性质的不均一性，波形和波幅将发生较大的变化，而脉冲余振、天线方向图形、天线的地表偶合程度、系统内部的干扰、地下介质的不均匀、反射面不光滑等引起的辐射效率、散射的变化以及剖面旁侧的绕射等干扰，均使实时记录图像复杂化。

When the reference beam is incident on the phase grating, the system will diffract out the reference beam and reconstruct the central data part.

最后在读取资料光之光路上加入绕射光学元件，使资料光入射绕射光学元件后产生绕射偏折，利用影像侦测器撷取重建之资料讯号。

So the physical components such as particles,chemical composition,mineral component,soluble salines and microstructure of leoss along the line of Fuxin-Chaoyang freeway,are tested and analyzed by means of particle analysis,X radial diffract technique,chemical test and scanning electron microscope.

利用颗分试验、X射线衍射技术、化学分析技术及扫描电镜测试技术，对阜新-朝阳高速公路沿线黄土的颗粒组成、化学成分、矿物成分、易溶盐，以及原状黄土的微观结构进行了测试、分析。

Under the influence of geography, plant,building and moving objects, electromagnetic wave will reflect, diffract, scatter, andcause signal multipath time delay and Doppler frequency spread, make the quality ofcommunication bad.

但电波因受到地形、植被、建筑物及移动物体等因素的影响会引发反射、衍射、散射等现象，产生电磁波信号的时延扩散和多径衰落效应，影响通信质量。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
