The influence of reaction pressure on the growth of diamond film is analyzed by using CH3CH2OH and H2 to serve as pressure source,the microwave plasma CVD to accumulate diamond film,the metallographic microscope(×400) to obseve the accumulation effect,and the X-ray diffraction to detect the quality of the film.

With the development of automobiles, materials and other industrial sectors, thedemand of metallographic microscope is growing significantly, especially the automaticmetallographic microscope which has high magnification and high degree of automa-tion.

The traditional way of taking photomicrographs by metallurgical microscope can not satisfy the computer ′s needs.

The remote monitoring and controlling syst em for a large scale metallurgical microscope is introduced in this paper.

And the video - frequency metallurgical microscope turns optical signels into vision signals and shows the metallurgical structure on the display screen to make teaching and research easier.

This paper introduces a design of metallography tissue digitalization data collecting system which is based on CCD and metallography microscope,and with an emphasis on the theory of optical imaging of JX-4 metallography microscope and the selection of other devices and the design of optical interface in acquisition system.

Introduced the working principle of computer-metalloscope,compares it with conventional metallographic examination,and discuss the application of computer in metallographic examination.

A method is introduced to measure the thickness of films with the focal plane of a metalloscope in the paver.

The shape, distribution and density of etch pits on the (101) face was observed by metalloscope after chemical etching.
