非均匀形核 meaning in English

heterogeneous nucleation

As foamer , had been made with buffer ph solution . in which the composition and reaction rale of combination process must be controlled . with scanning electron microscopy ( sem ) , it is clear to observe that the shape of tih2 powder is changed from sharp after coated
试验分析表明，以ph溶液作为缓冲沉淀液，通过控制反应成份浓度和速度，利用非均匀形核法可以实施al _ 2o _ 3包覆，其中溶液浓度和ph值对包覆效果影响最大，是保证非均匀形核包覆的关键。
The thermodynamic conditions of decomposition of the foaming agent tih2 , homogeneous and heterogeneous nucleation in high - temperature solid and liquid , growth and movement were achieved to demonstrate the trend of pore evolvement in this paper . moreover , according to the characteristics of in - situ gas foaming , the equations of the height change of foaming samples with heating time were primarily established to study the behavior of foams and to guild the experiment processes
另外，论文通过大量的热力学分析，得出了发泡过程中发泡剂分解以及气孔在固液态时的均匀形核和非均匀形核、气孔的生长和运动等热力学条件，揭示了气孔演化的趋势；论文还根据内生气源发泡的特点，初步建立了高温熔体中气体发泡高度随时间变化的方程，为进一步深入的研究发泡机理奠定了一定的基础。
