Nd and Y showed more evident effects than Gd and La due to lower temperature of eutectic reaction with aluminum. In order to investigate mechanism of the formation of the intercellular dispersoid which is being in debate and possibility of suppressing the dispersoid, a nucleation kinetic model which including unsteady nucleation and effect of alloy element was established.

Al-Fe-Mo-Si-Zr-Ti合金粉末具有四种凝固组织，初生Al〓〓，α-Al与Al〓共晶，胞晶及显微胞晶，合金元素Mo的加入，显著提高合金粉末凝固前的过冷度，使10~40μm粉末的凝固机制发生了变化，由导热控制型转变成溶质扩散控制型，从而基本上消除了该尺寸范围内粉末凝固组织中共晶成分和初生相，但对大于40μm的粉末，因共晶区富Zr核心的优先形成而使Mo的作用效果不明显。

DMBQ, ferulic acid and resorcin were effective chemical signal substances in the process of seed germination and haustorium formation of Cistanche deserticola. 4.The embryo is consist of 12 cells, the endosperm cell degraded so as to provide nutrition for the embryo development .As a result, germ tube differentiated from the embryo and came out through micropylar end, the small cell at the tip of the germ tube held the capacity of cleavage and the other cells grew big ,so the germ tube elongated .The anterior extremity of germ tube swelled to form haustorium under chemical substances treatment, the haustorium cell stained ,especially its portrait because of the lignification of the cells.

肉苁蓉种子的胚是由12个细胞紧密排列形成的圆球状胚，球形原胚分裂增殖的同时，胚乳细胞分解，为胚细胞的增殖提供营养，最终胚上分化出的芽管由珠孔端冒出，芽管前端细胞较小，具有旺盛的分裂能力，后部细胞体积增大，芽管逐渐伸长，在化学物质的诱导下，芽管由中部至前端细胞膨大分化出初生吸器，初生吸器呈帽子状，而这些细胞比其周围的细胞着色深，吸器纵向局部区域的番红染色加深，细胞高度木质化。

This paper deals with the effect of melt overheating treatment on the microstructure of Al-Si hypereutectic alloy.

过热可使合金的初生硅细化，随过热温度的升高，合金的初生硅尺寸逐渐减小。

During annealing the ribbons with 5% at Pd, Zr2Ni crystallizes first, and then the residual amorphous matrix transforms into Zr2Pd.

当Pd的加入量为5at%时，初生相仍为Zr2Ni，随后部分残留非晶转变为Zr2Pd；当Pd的加入量达到10at%时，初生相为Zr2Ni和少量Zr2Pd并存；当Pd的加入量达到20at%时，初生相为明显的Zr2Pd。

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。

Effects on reproductive performance: The normal delivery of group B,C and D were 80%、93.33%、93.33%,respectively,were improved by a certain extent comparing with the control group; The mean birth weight of calves were not significantly different between the trial and control groups.But numerical datas shown that supplementing Zn-Met in dietary had the tendency to increase the birth weight of calves; Supplementing Zn-Met in dietary can make dairy cows express empathema earlier,and significantly(P.05).Among the trial groups,the advanced extent of the group C was comparatively large(5.8d);The oestrous cycles were all in normal range and not significantly different; The levels of serum PRL of group B,C and D were significantly(P.05) 1.46 ng/ml、3.08 ng/ml、3.45 ng/ml higher than the group A.

TiC has a refinement to both primary and eutectic borides, some of which can act as the substrate for primary boride making refinement, the remainder inserting into the primary boride imped it growing in matrix; TiC inserting into the primary boride impedes the eutectic boride growing on the primary boride and decreases the formation of large block eutectic boride.
