It is shown that air showers induced by the primary gamma-rays can be effectively separated from the air showers induced by protons (background) using the combination cuts on the arrival time fluctuation and the lateral distribution width of secondary particles in air showers. This method can be used for reducing the background of hadrons in searching for gamma-ray point sources for ARGO experiment coorperated by China and Italy at Yangbajing. The effect of this method on the significance of gamma-ray signals is also estimated.

Based on the Telesis package written with Fortran which is the code for kinematic fitting, we design a new package called Telesis + + with most popular Object-Oriented C + + language. The packages written with C + + have many characteristics such as flexibility, compatibility and expansibility. The result shows that Telesis + + has the same result with the Telesis. Telesis + + can be one of physics analysis tools for BES III in the future.

In the real world N-c = 3, we investigate the origin and character of color and kinematics aspects in interference terms. We find that the production probability of color singlet chain states decreases from 83 %, 77 % to 67 %, 58 % for q (q) over bar + 2g and q (q) over bar + 3g system respectively after considering the interference terms. Especially, the production probability of color separate states increases to twice of that without interference terms for q (q) over bar + 2g. Hence when n is larger, we can expect that the production probability of singlet chain states will be far less than 1 and that of color separate states will significantly increase when n is larger.
