We have studied the kinetic effects on ballooning-mode more completely from the gyro-kinetic theory. Here we have consideres the effects of the following factors, i. e., collision, hot-ion components such as neutral beam injection or fusion α-particles, particle diamagnetitc drift, ion gyro-radius ,as well as trapped particles. It has been shown numerically that both gyro-radius of ion and trapped particles have stabilizing effects on ballooning-mode, whereas the collision term has the destabilizing effect besides, the kinetic theory reproduces the results given in Ideal MHD theory, i.e. the shear can improve the stability of ballooning-mode.
