The results show that the modificator Mg can cause thermodynamic undercooling , and it may absorb in the crystal faces of preferential growth of carbides, which can slow down carbides growing up on plate type and make them tend to be fine, isolated and passivated, and thus the impact toughness is improved greatly.

研究结果表明：在过共晶高铬白口铸铁结晶过程中，变质元素Mg不仅造成热力学过冷，而且Mg可能吸附于碳化物择优长大的晶面上，起到阻碍碳化物片状长大的作用，使碳化物趋于细小、孤立，且边部钝化，使冲击韧度显著提高。

When the undrawn films were annealed atthose temperatures, the morphologies in the lamellar crystals had change. WAXDand iR studies shown that the crystallinities incrcand, dimensions in (002) and(020) normals increased while that in (200) fold had slight decreases. The rela-tionship between the orientation of the drawn UHMWPE gel-films and the struc-ture changes and the optimum drawing temperature had been disscussed.

通过IR及X－ray衍射等方法研究发现，拉伸前用不同温度退火处理后，凝胶膜的片晶微结构产生明显变化，在对应于超高拉伸温度范围内，其结晶度增加，微晶的c和b轴方向尺寸变大，而a轴方向的尺寸减小，从理论上对这一变化过程作了考察，并讨论了超高拉伸取向性与这些结构变化的关系以及可超拉伸取向性的最佳温度范围。

The solute redistribution caused by fluid flow is a main factor for the formation of unregular and other eutectic morphologies.

流体流动造成的溶质重新分配是产生非规则层片共晶及其它形态共晶的主要原因。

The cooling crystallization and the polymorphic transition processes of L-Serine in aqueous solution were real time monitored by PVM and FBRM. The results show that at a higher temperature, the anhydrous crystals form in club-shaped habit, while the temperature of the slurry was cooled under the polymorphic transition temperature, the club-shaped anhydrous crystals would translate to the hexagonal plate-shaped monohydrate crystals.
