Results show that sulfides can be refined and disperse evenly after continuous multi-pass rolling, with the average width of sulfides being 4.91μm, the average length being 14.27μm, the average aspect ratio being 3.03, and the average area being 44.72μm2. The sulfides can refine the microstructure due to their pinning effect, and the reefing effect shows Zener relation.

It is shown that both strength and delayed fracture resistance of 42CrMoVNb steel increase when its grain size is refined from 20 m to 4 m, but they do not increase when refined to 2 m.

结果表明，随着晶粒细化， 42CrMoVNb钢的强度和缺口拉伸延迟断裂抗力逐渐提高；但当晶粒细化到2 m时，强度和延迟断裂抗力均不再提高。

The results show that the grain size is refined by the addition of Nd or Dy, especially combined addition is better than single addition. With the addition of 0.2 % Nd and 0.6% Dy, the grain size is reduced from 150 μm to 60 μm. Combined addition with two rare earths elements makes the tensile strength, yield strength and elongation of ZK10 alloy increase to 191.0 MPa, 69.0 MPa, and 16.6%, increasing by 89%, 43%, 232% respectively, compared with ZK10 alloy without RE element.

结果表明：ZK10镁合金中分别加入Nd和Dy均能细化晶粒，且Nd和Dy同时加入的效果优于单一加入的效果，当同时加入质量分数为0.2% Nd和0.6% Dy时，合金的平均晶粒尺寸由原来的150 μm细化至60 μm，使ZK10合金的抗拉强度和屈服强度分别提高至191.0 MPa和69.0 MPa，伸长率达到16.6%，与未加入稀土的ZK10合金相比分别提高89%，43%和232%。

The results show that dynamic softening is easy to occur in these ingots and flow stress becomes steady finally; the material constants of hot deformation are procedural parameters that stress-level coefficient α, strain rate sensibility exponent m and deformation activation energy Q are all increased with strain increasing, while stress exponent n is decreased gradually; the values α and m of the alloy homogenized are the biggest and the value n is the smallest, dynamic softening effect of the alloy is the most obvious, which can deform evenly; influence of strain on the value Q of the alloy homogenized is a little and the average value of Q is only 176.5kJ/mol, so the alloy is easy to deform; the alloy matrix shows the regular recrystallization grains when the strain is 50%; dislocation cell structure re-formed in the grains with increase of strain.

结果表明：经不同处理的Al-1Mn-1Mg合金均易发生动态软化并最终呈现稳态流变特征；热变形材料常数是过程量，随应变量的增加，应力水平参数α、应变速率敏感性指数m和热变形激活能 Q 随之增大，而应力指数 n 则逐渐减小；均匀化退火后，铝合金的α和m值最大而n值最小，动态软化效果最明显且变形均匀，在该状态下，铝合金的 Q 值受变形量影响小，平均仅为176.5kJ/mol，易进行热变形；当应变量为0.7时，基体呈现规则的再结晶晶粒组织，随着应变量的增加，晶内重新形成了位错胞结构。

The experiments proved the degree of stability reached 0.28μm and the definition of repetitiveness reached 1.376μm.

做出了实验样机，并进行了相关实验，实验结果表明，测量稳定度达到0.28μm，重复性精确度1.376μm，达到了良好的指标水平。

The essential mathematical feature upon which this technique is based is that a square m*m matrix C of non-negative real numbers representing, for example, pairwise comparisons of the importance of element of the next higher tactics level has a characteristic equation which yields a dominant eigenvalue λ and a cprresponding right eigenvector x

基本数学特征后，该技术的基本思想是方形m*M矩阵三非负实号码代表，例如成对比较的重要组成部分，未来较高的战术水平有一个特性方程而产生主导特征和cprresponding权向量xwherec=与cij和cij=满足一致性条件

The axial runout of the commercial disc is about 300 μm. The equalizer used in this study was designed for 500 μm.

一般市售碟片的轴向摆动约为300 μm，本研究将轴向摆动之范围提高到500 μm，来设计所需要的等化器。

A.D. M. El Zawahry, M.D., of Cairo Egypt reported that he used Aloe Vera on his patients suffering from seborrhea, acne, alopecia, chronic leg ulcers, vulgaris, and hair loss.

1973年，M.EL.Zawahry M.D讲述他用维拉芦荟来治疗患有皮肤炎、痤疮、斑秃、慢性溃疡、脱发等病症的患者，并证明芦荟对治疗这些疾病有奇效

The conclusions can be drawn as the following:(1) According to the theoretical calculation, the porous C/C preforms with uniform pores radius from 10 μ m to 1300 μ m are beneficial to infiltration of liquid silicon. The growth of SiC was controlled by the self-diffusion of carbon atoms.
