The microstructure of hardened layer and formation mechanism were investigated.The microstructure of hardened layer consist of the completely hardened region and the transition region.The completely hardening region is composed of fine acicular martensites,residual austenites and a few dot-like carbonides.From surface to bottom in the hardened layer,the microstructure varies from fine to coar...

结果表明：采用适当的磨削参数可满足该钢所要求的淬火温度，进而获得适宜的淬硬层显微硬度和强化层深度；磨削淬火层由完全硬化区和过渡区组成；完全硬化区主要由细小针状马氏体组成，从表面到里层，组织形貌呈现&细→粗→细&的变化规律，其形成机理是热-力耦合作用影响磨削淬火过程中的奥氏体晶粒大小及其位错密度，并将直接影响转变后的马氏体组织形貌。

Expression patterns of genes differentially expressed in starch metabolism and cell cycle during endosperm development7 DAP kernals, 15 DAP endosperms and 25 DAP endosperms of B73, ae/wx and sh1 were used to study the expression patterns of 18 differentially expressed genes in sugar metabolism and 9 differentially expressed genes in cell cycle. We found that the expression patterns of Pul, SBEⅡa, UGPase, SUS3, SSⅡa in sh1 and Sh2-1, SUS3, SSⅡa in ae/wx were altered, revealing that these genes may interact with each other.

The soft temperature of copper matrix could be effectively improved and thermal expansion of copper matrix could be effectively restrained by the AlN particles; Under the action of porosity and thermal stresses, the thermal expansion curve of AlNp/Cu composites became non-linear with the particle volume contents increasing to a certain extent.

结果表明：AlN的加入能够提高铜基体的软化温度且对铜基体的热膨胀起到明显的约束作用；在孔隙与热应力共同作用下，AlN颗粒含量达到一定程度时，AlNp／Cu复合材料膨胀曲线随温度的上升将产生非线性变化；加热过程中热应力造成的基体塑性变形使热循环后复合材料存在残余正应变。

Flounder FoxD1 mRNA was over expressed in one cell of the two-cell stage zebrafish, MyoD expression in the somites on one side was reduced, but the expression in the adaxial cells was not affected; Myf5 expression in the presomitic mesoderm, adaxial cells and somites on one side was reduced.

在斑马鱼中过量表达FoxD1后，MyoD在一侧体节中的表达受到了严重抑制，而在近轴细胞中的表达未受影响，Myf5在体节前中胚层，近轴细胞，及体节中的表达都受到了抑制。

When aborted rats in group E were treated with the dose of 50 IU/g IFN-γ, expression of TNF-αin this group was compared with the other four groups, the results were as follows: Compared with group A, the nucleus pre-opticus medialis, nucleus pre-opticus mango celluaris, nucleus periventricularis hypothalami, nucleus ventromedialis hypothalami, nucleus dorsomedialis hypothalami, nucleus arcuatus hypothalami and pars intermedia had a highly expression of TNF-α, in the other nuclei of hypothalamus, neurohypophsis and adenohypophysis, the change was not significantly, the expression of TNF-αin follicle and corpus luteum were decreased distinctly, the variation in uterus was slight and no difference was exsited; Compared with group B, the expression of TNF-αin nucleus nucleus lateralis hypothalami, nucleus ventromedialis hypothalami, nucleus arcuatus hypothalami, adenohypophysis and uterus presented a remarkable enhancement, conversely, the TNF-αexpression in the nucleus pre-opticus medialis, nucleus pre-opticus suprachiasmaticus, nucleus supra-opticus, nucleus pre-opticus mango celluaris, nucleus periventricularis hypothalami, nucleus paraventricularis hypothalami, neurohypophsis, follicle and corpus luteum had been significantly decreased; Compared with group C, the nucleus pre-opticus medialis, nucleus ventromedialis hypothalami, nucleus dorsomedialis hypothalami, nucleus arcuatus hypothalami, adenohypophysis, pars intermedia and uterus had upregulated the expression of TNF-α, however, it was decreased in the nucleus periventricularis hypothalami and corpus luteum; When compared with group D, the expression of TNF-αin nucleus lateralis hypothalami, nucleus dorsomedialis hypothalami, nucleus ventromedialis hypothalami, pituitary, follicle and ovary stroma were obviously enhanced, while in the nucleus supra-opticus and nucleus arcuatus hypothalami, the situation was definitely opposite, in the other parts, the change was not significant.
