等长轴的

This paper extracted and analysed 11Math-Mophological Features such as Area, Perimeter, X-Length, Y-Length, Shape-Parameter, Lobation, Sphericity, Circularity, Roundness, Eccentricity and HoleNumber. Based on 40 species of insects which belonging to 8 Orders, 25 Families. And then ranks the accountability of 11 features each in insect identification while assessing their implication to insect taxonomy on levels of Order, Superfamily, Family and Species. More than those, also describes the kinship among the insects of various categories within the same level from the perspective of mathematical morphology through cluster analyses.

The results show that the effect of addition or no-addition of degasser on grain refinement of Al-5.0%Si alloy ingot is...

结果表明，除气剂的添加与否对Al-5%Si合金铸锭组织的细化没有影响，铸锭由粗大的柱状晶组织构成；采用合适的超声波处理时间，Al-5%Si合金铸锭的等轴晶获得率大幅度提高，可使整个铸锭组织变为细化的等轴晶组织；超声波振动时间过长将导致铸锭内气孔的增加；根据克劳修斯-克拉柏龙方程，某一强度的超声波引起的压力冲击波作用，导致液相转变为固相，引起了超声波的细晶作用。

The influences of Ce on the microstructure and mechanics performances of Ti-Fe-Mo-Mn-Nb-Zr alloys were studied and presented in this paper. The microstructure of no-Ce Ti-Fe-Mo-Mn-Nb-Zr alloy was thick, long and dendritic,and the microstructure of alloy was fined by Ce. With the increase in Ce wt%, the microstructure became equiaxial gradually.

研究了稀土 Ce对 Ti- Fe- Mo- Mn- Nb- Zr合金组织与力学性能影响，结果表明：不含 Ce的为粗大的长枝晶组织，加入 Ce后组织有所细化，并随 Ce量增加而逐渐等轴化，直至形成等轴晶；硬度方面随 Ce的加入有所降低；在 Ce含量较少时随 Ce的增加压缩强度也增加，但当 Ce含量增大一定量时，Ce增加降低了压缩强度。
