This paper presents the research method for the mathematical model on screening process and describes the system of testing coal probability sizing screen GS300 × 2000 in pilot plant.

Improvement of GS type probability screen vibration frame;

The practice process of the technological parameter of raw coal sizing screen rectified by Tianzhuang Coal Cleaning Plant was introduced in this paper,and it also gropes for the traditional size range of lump coal and slack coal.

Variation and probability grading of main quantitative characters of fruit in strawberry germplasm resource;

The high-speed video system and the image processing method were used to experimental study on the screening process of agricultural materials and the relationship between the major working parameters and materials passage probability was received through the range analysis.
