Strategic Study of CAE 2003, Volume 5, Issue 7, Pages 58-61
In order to confirm the dependence of the resistance of cavitation erosion and abrasion (CEA) on the common properties of materials, four typical materials (WC coating, NiCr alloy coating, boron stainless steel and titanium) were used to do the experiments of CEA and cavitation erosion (CE), to do corrosive experiment, and to test their hardnesses. The experiments results indicated that all resistance to CEA and resistance to CE depend on the hardness and the corrosive resistance of materials. The high hardness is the first factor of good resistance to CEA, strong corrosive resistance is the second factor. Meanwhile, the strong corrosive resistance is the first factor of good resistance to CE, high hardness is the second factor.

Strategic Study of CAE 2000, Volume 2, Issue 2, Pages 41-46
The conception of the generating lock P <G ,X, X´> and the central encrypting system composed of P<G ,X, X´>with data generating technology are proposed in this paper[3〜6]. These systems include the generating lock P<G ,X, X´> and single-tooth central encrypting system, and the generating lock P <G ,X, X´> and multi-tooth central encrypting system. The single-tooth encrypting-decrypting algorithm multi-tooth encrypting-decrypting algorithm, multi-tooth static encrypting-decrypting algorithm, multi-tooth dynamic encrypting-decrypting algorithm as well as the structure character of central encrypting system are provided. The paper points out that arbitrary two persons A and B can choose irregular distributed positive integer sets, XA={x1, x2, …,xn}, XB ={x1,x2,…xm}, m≥4, n≥4, XA≠XB , respectively and complete their secret communication with P < G, X, X´>. The experiment result shows that the method proposed has good application character and security character.
