With smaller speed, it refined the dendrite, and, with larger speed, it coarsened the dendrite.

说明流动对枝晶组织有双重作用，流速较小时细化枝晶，流速较大时粗化枝晶。

Experiment results show that though the grains of the heat-affected zone are seriously coarsened due to the effect of welding thermal cycle, there is no softened zone and the strength of the welded joint doesn′t decrease because the transformed microstructure is different from the original one.

结果表明：经过焊接热循环的作用，虽然热影响区的晶粒明显粗化，但由于所获得的二次组织形态与钢筋原始组织不同，热影响区未发生软化，也不存在焊接接头强度下降的问题。

When the sample was subjected to high temperature for a long time before test, its co-continuous structure would be easily coarsened and disintegrated under the driving of interfacial tension.

试样在测试前长时间处于高温熔体状态时，其共连续结构很容易在界面张力的驱动下发生粗化和破碎，所以得到的共连续反而变窄。

The results showed that for both of the alloys grains were obviously refined to same extent with increase in Ti content, and the grain sizes were coarsened to some extent due to evident fading of Ti effect during melt holding period....

随着保温时间的延长，所有合金的晶粒尺寸均不同程度发生了粗化，Ti对晶粒的细化效果明显发生了衰退。电解加钛铝合金晶粒细化效果的抗衰退能力优于熔配加钛铝合金，这种趋势对Ti的质量分数为 0 。1%～ 0 。2 %的合金特别明显。

The results show that when an electromagnetic field with 1000 Hz frequency and 20 kW power is imposed, the surface roughness of hollow billets is decreased by 50%, the solidification structure is refined, the tensile strength is improved by 40%, and the elongation is improved by 50%, averagely; when the power is heightened to 30 kW, the solidification structure is coarsened and the mechanical properties are worsened.

研究结果表明：当施加频率为1kHz的电磁场时，空心管坯的表面粗糙度降低了约50％；当施加功率为20kW的电磁场时，空心铜管坯的组织得到细化，抗拉强度提高了约40％，延伸率提高了50%；当施加30kW的电磁场时，铜管坯组织粗化，力学性能下降。

The alloy is not splitting after the aged treatment at 1000℃ for 2000 h when the critical size ofγ' phase reaches about 1.5 μm while it is coarsened to form the rafts.

DZ951合金在1000℃长期时效2000 h后，γ'相尺寸达到1.5μm也不发生分解，而是粗化形筏，形筏的驱动力为弹性能和界面能的降低。

Experiment results show that though the grains of the heat-affected zone were seriously coarsened due to the effect of welding thermal cycle, there is no softened zone and the strength of the welded joint doesn't decrease because the transformed microstructure is different from the original microstructure of the rebar.

结果表明：经过焊接热循环的作用，虽然热影响区晶粒明显粗化，但由于所获得的二次组织形态与钢筋原始组织不同，热影响区不发生软化，也不存在焊接接头强度下降问题。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
