probe unit मीनिंग इन हिंदी

The probe unit is hermetically sealed .
A broad - host - range promoter - probe vector phn1006 was further constructed by transferring promoter - probe unit from phn1005 into ptr102
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
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
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
