Conclusion is made that calculation and test of the attraction force is key important in the probedesign. And some guiding advice is given to the design of the electro-magnet.
An innovative laser beam tracking system is proposed to eliminate the tracking and feedback errors. The open probedesign of the AFM makes the operation in liquid convenient and easy.
The working principle of the new viscosimeter with quartz crystal is discussed in this paper. The method for probedesign and the constitution of signal sampling and processing system are presented.
