使结晶

The new mold adopts the plane section instead of the funnel section of H^2 mold bottom, and shorten the length from 2100 mm to 900 mm. By simulating and optimizing the slab stress in molds, a new shape-funnel mold is designed, which have merits of lower slab stress and strain and smooth-transition of curve surfaces.

这种漏斗型结晶器将H^2，结晶器下部的漏斗区改为平面区，结晶器漏斗区高度由2100mm缩短为900mm，并通过模拟计算和优化设计，使结晶器内腔曲面形状各部分平滑过渡，使其具有生产铸坯承受变形应力小的优点。

Heat transfer between ingot and mold is then intensified by the quickened flow velocity of Al melt. As a result, the initial solidifying point on the ingot surface in mold moves upwards to decrease the height of contact zone between the melt and mold so as to improve the surface quality of ingot.

铝熔体流动速度的加快能增强石墨环与铝熔体之间的换热，使结晶器内铸锭表面初始凝壳点位置上移，减小了铝熔体与结晶器的有效接触高度，提高了铸锭的表面质量。

With the growth of heat treatment temperature or time, the crystallinity increase and the spherulite size and its distribution has a little change.

热处理温度的提高或时间的延长均使结晶度逐渐增大，但平均球晶尺寸和球晶分布宽度变化不大。

The study of vertical channel with high field effect mobility by Ni induced lateral crystallization, which can form larger grains on channel regions and reduce grain boundary defects. We detect the method of Ni induced lateral crystallization through high field effective mobility, but that accumulates too much Ni on floating N+ region and causes defects and metal contamination. As Ni is used to form silicde and then proceed to low temperature annealing, we can observe the floating region that has no Ni acumination regions or contaminations. This aids us in obtaining good electronic performance of this device, not only the remote field effective mobility but also the vast improvement of sub-threshold swing and on/off currents.

接著，是延续垂直通道的研究，希望能有效的提升电子迁移率，因此以镍金属诱导横向结晶的方式使通道形成较大的结晶，减少矽晶粒之间的缺陷，而在初步的研究，发现以镍金属直接诱导横向结晶的方式，经由低温长时间回火之后，由於镍金属扩散的关系，完成诱导结晶之后，有过多的镍金属聚集在顶部参杂的中间区域，而造成过多的缺陷累积，虽然电子迁移率有效的提升，但整体的电性并不如预期，因此提出先形成镍金属矽化物后，将未反应的镍金属或金属氧化物去除之后，再进行镍金属矽化物诱导横向结晶处理，经由结果观察得知在顶部掺杂区域部分没有明显的镍金属累积或污染，并且得到很好的整体电性，除了电子迁移率有效提升之外，次临界特性以及导通电流都能有效改善。

DSC and WAXD studies showed that the block copolymers were meltable, and due mainly to the flexible nylon6 segments.

采用DSC热分析的方法，结合WAXD，研究发现，所合成的嵌段共聚物具有可熔融的性质，主要的转变来自柔性的尼龙链段；通过对聚合物空间立体结构的改造，分子链中间位结构的引入以及两嵌段组分分子间和分子内的相互作用强烈影响嵌段共聚物的结晶行为，使结晶更不完善，晶体结构更为疏松，自聚集倾向在很大程度上得到抑制。

In comparison with bugle shaped nozzle, bifurcated nozzle downward jet angle 45°, cow-nose nozzle and three-hole nozzle, in all, the last two are better than the former and bifurcated nozzle downward jet angle 45 is better than bugle shaped nozzle; Cow-nose nozzle is helpful for guaranteeing the product's quality, in order to protect jet flow from eroding the strand at narrow face, gain uniform temperature distribution at cross section and decrease heat flux, adding the block's width to 100 mm. Three-hole nozzle is advantageous to increase flux and casting speed, but should avoid weak shell thickness in the center broad. In the real production, setting the SEN's immersed depth or plugging the hole at the bottom can adjust the flow and temperature distribution in the mold.

对比喇叭形水口，双侧孔水口(45°)，牛鼻子水口和三孔水口，总的说来后两者优于前两者；而双侧孔水口(45°)又优于喇叭形水口；牛鼻子水口和三孔水口比较各有特点，前者对保证铸坯质量有利，为防止流股对窄面的冲击，增加挡块宽度到100 mm，可使结晶器横截面上温度分布更加均匀，降低窄面热负荷；后者对增加流量，提高拉速非常有利，但要防止中孔射流过强导致铸坯中心坯壳变薄，在实际生产中可通过控制水口浸入深度或塞住浸入式水口的底孔来调节结晶器中的流动与温度分布状态。
