Abstract：

In an effective Lagrangian model we find that the N^*(1535) resonance contribution might be important to the interpretation of the present data of the pp→ppη´ and pn→dφ reactions. The strong coupling strength of N^*(1535) to η´ and φ are indicated, and the possible implication to the intrinsic component of N^*(1535) is explored. These results may provide hints to the real origin of the OZI rule violation. It is stressed that further measurements could be performed at the Cooling Storage Ring (CSR) at Lanzhou of China.
