Microstructural observation revealed that a lot of epitaxial growth fibrous AlN polytype occurred in matrix. Y_2O_3 seems to act as a densifier for in-situ formation material and as medium for growth of fibrous polytype. SiO_2 is the growth promoter for fibrous polytype. The occurrence of fibrous polytype may increase the strength and toughness of AlN ceramic composite material.

In the computer simulation aspect, following work has been down:At first, the Wolfgang Schreiner's model is employed and extended to a new computer arteriole optimal growing model. Many new algorithms are described, such as signal tracing, resistance calculating, resistance balancing and flow balancing. With these algorithms and methods, the arteriole networks can be grown successfully on microcomputer.Secondly, a growing-network ordering method, which is called auto-centripetal ordering method of the growing networks, can be employed to order the growing networks to calculate the average parameters of the networks in level series.

Result］ The extracted liquid from D. stramonium could decrease the germination rates of 4 vegetables and the seed germination of tomato and pepper. After treatment by 0.2, 0.4 g/ml extracted liquid , the seed germination of tomato and pepper were decreased by 10.2％, 9.4％ and 46.7％, 34.7％ than that of CK resp. The extracted liquid at 0.2 g/ml could inhibit the growth of vegetable root, but had some promotion on growth of vegetable stem. The extracted liquid at 0.4 g/ml had the strong inhibition on the growth of vegetable root, but its inhibition on growth of vegetable stem was greatly variable in different species.

The results show that the undissolved silicon particles in the melt become the cores of primary silicon precipitated in solidification and there is a close relationship between the shape of primary silicon and undissolved silicon particles. The growth of silicon follows not only the twin plane re-entrant edge mechanism, but also layer mechanism as well. Meanwhile, the shape of primary silicon also relies on kinetic surroundings, such as the transmitting of solute. At higher overheating temperature, the shape of primary silicon becomes the star-shape and tree-shape.

结果表明：重熔过程中熔体中未溶解的硅相粒子，在凝固过程中可成为初生硅生长核心，并且未熔颗粒与初生硅形状之间存在明显对应关系；初生硅的生长机制不是惟一的，既可以以孪晶凹角机制生长，还可以以层状机制生长，初生硅最终形状还要取决于溶质传输等动力学环境；随着熔体过热温度的升高，凝固组织中初生硅形状由多边形向星形及树枝状转变。

Studies also indicated that genistein exsists not only in soybeans but also in many kinds of plants such as vegetables and fruits.As a potential anticancer agent, the actional mechanisms of genistein mainly includes as follows:First, genistein can depress the activity of protein tyrosine kinase and transduction pathways for the phosphorylation of receptors and mitosis signal. So genistein can lead to cells' proliferation depressed. Second, genistein has minimal effects of phytoestrogens. It can be combined with estrogen receptor and improve the synthesis of cellular sex hormone binding glulobin, and improve the activity of UDP-glucuronyl transferase. Through these pathways, it can inhibit the cell activity of breast cancer and prostate cancer.
