查询词典 dendrite

The concept of secondary recalescence is outlined. It is pointed out that the inflection point occurred during recalesence stage only indecates the heat requirement for dendrite remelting, while the inflection point resulted from heat release during new phase formation can be regarded as a strict secondary recalescence.

Besides, the dendrite and the boride morphology in the big grain and small grains are same. All these results show that the boron addition does not influence the solidification process, but promote the β→α transformation, so still grain refined lamella can be gained at last.

这些实验结果表明：硼化物对Ti46Al8Nb基合金晶粒的细化作用主要不是通过改变 L →β的凝固过程得到的，而是通过影响凝固后的β→α固态相变来实现的。

Through the investigation for the effect of the experimental parameters, such as the electrodeposition time, the voltage and the concentration of sodium dodecyl sulfate, on the shapes of dendrite-like copper crystals, the formation process was studied and it went through the nucleation, growth and revegetation process

通过研究各实验参数，如电沉积时间、电位和十二烷基硫酸钠的浓度对枝状晶体形貌的影响，发现枝晶铜的生长过程经历了成核－生长－再生长的过程。

Dendrite growth has been simulated with the phase field method and finite difference schemes on a two dimensional rectangular domain with a uniform square mesh.

采用相场模型和有限差分方法，模拟了过冷纯金属熔体的枝晶生长，计算区域为二维正方形均匀网格。

The results indicate that with increasing the strain at 280℃, the dendrite arms of AZ91D alloy get broken or stretched-out. With increasing the predeformation temperature under 20% strain, the deformation style of the dendritic structure of AZ91D alloy changes gradually from fragmentation to directional bending.

结果表明：形变温度为280℃时，随着形变率增加，部分枝晶臂逐渐伸长，枝晶破断现象加剧；形变率为20%时，随着形变温度的提高，组织的形变方式逐渐由以枝晶断裂为主转变为带有方向性的弯曲。

But also effects of the diffusion of solute in liquid and interface curvature as well as the enrichment of solute on supercooling of dendrite tip.

结果表明，树突和轴突的尺寸会影响信息的传输速度，从而影响信息在神经元间传递的时机；胞体部分是整个神经元响应的核心单元，决定了信息是否能被传递到轴突末端；轴突的主要作用是对胞体的发放响应进行优化，使得轴突末端的发放形式更有利于信息传往下一级神经元。

Boron can also affect the dendrite of hypoeutectic Ti-Si eutectic alloy.

铝是钛合金的重要元素之一。
