probe unit meaning in English
测试装置；检测器；探头
探查设备
Examples
- The probe unit is hermetically sealed .
探头装置是密封的。 - A broad - host - range promoter - probe vector phn1006 was further constructed by transferring promoter - probe unit from phn1005 into ptr102
5 .发现一个发较强绿色荧光的大肠杆菌突变株，提取质粒命名为phn122 。 - Moreover , the horizontal system is much more stable than the conventional one ( vertical afm ) , which usually has a high center of weight , a poor aseismatic capability , and the weight of the probe unit may potentially make itself creep down along the guide way
此外，卧式afm克服了传统立式系统重心高、抗震性差，以及探头本身的重量可能使其沿导轨向下蠕动，从而降低系统的稳定性和重复性等缺点。 - The main performances of the afm were in the advanced level around the world . the probe unit of the horizontal afm includes a photo - electronic detection unit with a particular optical - beam - deflection path , a regulating block of the setpoint of imaging force , the xy scanner and z feedback controller , the coarse adjusting and fine adjusting mechanism for the sample approaching to the probe tip . the powerful circuits of preamplifier , as well as the circuits of xy scanner and z feedback controller were developed
成功研制了卧式afm探头，包括特有的微悬臂偏转量的卧式光电检测系统、 afm成像工作点(即原子力的预设置点)的调节机构、 jy }艺扫描与反馈控制器、样品的粗调与微调机构;自行研制了高性能的psd前置放大电路、 xy扫描控制电路和z向pid反馈控制电路系统;设计了a / d & d / a控制接口，独立开发了性能完善的afm扫描与控制软件系统及功能强大的图像处理软件系统。 - The significant characteristics of the new afm include : ( i ) it has a horizontally designed probe unit , and the direction of cantilever ' s weight was perpendicular to the atomic force , thus the effect of cantilever ' s weight on the imaging quality can be effectively avoided ; ( ii ) it owns a particular path of optical beam deflection method for the measurement of cantilever ' s displacement
卧式afm探头系统的显著特色是，微悬臂重力与原子力方向相互垂直，有效地避免了重力对微悬臂及成像质量的影响，从而在设计方法上保证了afm的性能。本文在方法上的另一创新是，发展了独特的微悬臂偏转量的光束偏转法检测系统。
