In the standard measurement, such as bar code through a splitter, will be divided into two beams of light, a bunch of switch hitting the sensor photodiode array, and the other a bunch of change reach all parts of the observation mirror.

在水准测量中，条码的像通过一个分光器，将光线分成两束，一束转射到传感光电二极管阵列上，另一束转射到观测镜上。

A differential demodulation system of Laser Doppler is designed. Phase grating is adopt to obtain same intensity measured beams with big separative angle in the system,and by focusing the waists of two Gauss beams on the measured object with extender and collimating lens group, the smallest speckle and the superposition of plane waves are obtained.

设计了一种差动检波系统，采用相位光栅获得同光强、大夹角的测量光束，用扩束准直透镜组使两束高斯光束的束腰聚焦在被测物体上，得到最小光斑和平面波的叠加。

The length of the anterior bundle was maxium at 90° of the elbow flexion, the length of the posterior bundle varied with the change of the angle of elbow flexion, and a transverse bundle was unchanged.

前束在肘关节屈曲90°时最长，此时亦为最紧张状态，后束则随肘关节屈曲角度增大而逐渐变长，而斜束的长度不随肘关节屈曲角度的变化而变化。

Those roses were the first in a series of large bouquets that accompanied all the milestones in my life.

这束鲜花是第一束。往后，每逢我人生的里程碑，父亲总要送我一束鲜花。

Those roses were the first in a series of large bouquets that accompanied all the milestones in my life.

这束鲜花是第一束，后来，每逢我人生一个里程碑都会收到一大束鲜花。

The accelerator physics problems of the upgrading program were discussed here, which include the space charge effect on the very low energy beam line, non-parity acceleration at the injector cyclotron SFC, longitudinal match between two cyclotrons, strong magnetic field leakage afluence on the beam transfer at low and very low energy, residual first harmonic magnetic field in the main cyclotron SSC injection region, the low efficiency and beam quality of heavy ions after through stripper etc.

主要问题有：超低能束流传输的空间电荷效应的影响，扇聚焦回旋加速器SFC高频加速电压不对称对束流轨道的影响，用半频聚束的方式补偿两台回旋加速器的纵向不匹配，前束线上聚束器的工作模式的选取，强杂散磁场对超低能和低能束流传输的影响，分离扇回旋加速器SSC注入区过垫补磁场对注入束流轨道的影响，SFC和SSC的单圈引出，重离子通过剥离膜后的束流损失和束流品质的变坏等。

本文较系统全面地研究了杉木木束在高温干燥过程中的干燥特性，分析了各因素对干燥效益和能耗的影响，尤其是研究了木束内部水分迁移和热量传导过程的规律，建立并求解了传热传质的数学模型，为确定木束干燥生产的工艺参数及控制方案提供了理论依据。

The separation is based on the differential migration of the micelle and the surrounding water and the differential distribution of the solute between the mi celle and aqueous phase,therefore,the separation mechanism is very similar to th at of micella electrokinetic chromatography.

这种分离方式是基于胶束和水相在色谱过程中的不同迁移以及溶质在胶束和水相间的不同分配而实现的，其分离的机制与胶束电动色谱(mic ellar electrokinetic chromatography，MEKC)十分相似。

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.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

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。
