It is shown that under high undercooling condition, peritectic phaseξcan nucleate directly from alloy melt and the peritectic transformation can be suppressed.

发现在深过冷条件下，包晶转变可被抑制，包晶相能够从熔体中直接形核。

The novel inorganic ion-flocculant poly-nucleate aluminum hydroxy silicate-sulphate was prepared from aluminum sulfate and polysilicic acid under non-high shear condition.

在非高剪切力条件下，将硫酸铝引入到聚合硅酸中合成了新型聚硅酸硫酸铝絮凝剂。

It is shown that the surface of carbon fiber displays a high propens ity to nucleate PP crystallization. The nuclei density at the surface of carbon fiber is much higher than that in the bulk area, and the resulting radial growth produces a type of transcrystalline structure, and the characteristic temperature of crystallization increases with carbon fiber concentration.

碳纤维表面对聚丙烯结晶过程具有明显的促进作用，纤维表面成核密度轻高，结晶生长成为横穿结晶，结晶特征温度随碳纤维加入而有不同程度的升高。

Under middle and high heat flux, the liquid was degassed with the result that the boiling was pure liquid nucleate pool boiling, and, hereafter, the heat transfer coefficients could not be raised with increasing dissolved gas.

实验结果发现，低热通量时，相同热通量下的壁面温度会随著可溶解气体含量的增加而降低，主要原因是增加气体含量可以降低初始沸腾的热通量；中高热通量则因液体中所含的气体被除气所致，为纯液体核沸腾，热传系数无明显的提升。

Acicular ferrite microstructure in micro-alloyed steels, which nucleates around non-metallic inclusions, especially oxide inclusions, has high strength and good toughness and possesses strong grain-refining ability by itself. The ultra-fine grained steel with excellent weldability is likely to be produced by forming in materials a great number of fine and dispersive micro-inclusions which is helpful to induce AF to nucleate around them through oxide metallurgy technology.
