Abstract：
The problem of four generation straton weak coupling matrix is discussed. In several possibilities, the V-A coupling for the electroweak interaction of the four generation stratons is chosen and a coupling matrix of charged weak currents is proposed. It is a direct extension of K-M matrix. In order to illustrate the validity of the weak coupling matrix, two examples are given. The first example is used for the calculation of CP violation of K decays. In the second example, four generation weak coupling matrix expressed by mass of straton is calculated by means of horizontal gauge. An unexpected result is that the main decay mode of b straton is b→c+W^-. But in the case of 3 generations, the main decay mode of b straton obtained by the entirely similar model is b→u+W^-. Therefore, if this mode of horizontal gauge be verified in further experiments, there would be a reason for the extension of 3 generations to 4 generations.
