The result showed NaOH was the reasonable agent for changing pH value of cornhusk hydrolysate, and cornhusk hydrolysate could be preserved in the below conditions: pH value is pH4.0 and the sugar concentration of corn hydrolysate was from 80g/L to 160 g/L, multicomponent hydrolysate could be deposited within 48 h at the room temperature (20℃) or the low temperature (4℃) and must be preserved within 48~120 hours at the low temperature (4℃) from harmful fermentation by microorganism.

通过温度、pH、梯度总糖浓度以及调pH试剂等因素对玉米皮水解糖液存放过程中总糖浓度变化趋势的影响进行深入研究，实验结果表明：选取NaOH作为调pH试剂比较经济，且选择在80~160g/L、pH4.0条件下存放可较好保存糖液品质，确定出在0~48h范围内可选择低温(4℃)至室温(20℃)条件下存放，而48~120h范围内只能选择低温存放(4℃)，室温条件下较长存放时间的糖液易被环境微生物发酵利用掉，为玉米皮水解糖液的短期存放提供一定的帮助。

This work mainly studies the structure of cryolite in the high temperature.The paper is divided to double parts.

本论文主要研究冰晶石在高温状态下的物质结构问题，论文分为两部分，第一部分研究了高温状态下冰晶石(Na3AlF6)的物质结构问题，我们采用自制的加温炉体进行了室温300K到1075K的在位拉曼测试，记录了样品从室温到熔融状态下的峰位及半高宽的变化。

The result showed that, the effect of the synergistic reaction of alkyl-phenol-polyoxythylene ether phosphate dispersant TERSPERSE 4896, nonyl phenyl polyoxyethylene ether dispersant TERSPERSE 2210 and XG to suspension was different. Both the rheological curves were same presented as pseudoplastic fluid when they stored in R. T (18~25℃) for 10 days, but the rheological curve of suspension with the synergistic reaction of TERSPERSE 2210 and XG was changed to dilatant fluid when it stored in R.

结果表明，烷基酚聚氧乙烯磷酸酯类分散剂TERSPERSE 4896、壬基酚聚氧乙烯醚类分散剂TERSPERSE 2210与增粘剂黄原胶协同使用所得悬浮体系，室温(18~25℃)贮存10d仍表现出二者共同的流变特性，呈假塑性的流变曲线；但室温贮存150d后，含TERSPERSE 2210与黄原胶的悬浮体系的流变性质发生了明显变化，由假塑性流体向膨胀型流体转变。

For most of the whites, they should be chilled to a low temperature (7-10 degree); a sparkling or Champagne is supposed to be chilled to even lower temperature (4-7 degree); as to some light red wines, the comparatively coldness is good for us to detect the fruitiness of the wine; and for those medium or full red wines, it is unnecessary to keep it cool, just drink at the room temperature (16-18 degree).

对一般的白葡萄酒来说，都应该冰镇一下(7-10度)；气泡酒/香槟则要更低一些(4-7度)；对于那些酒体比较轻盈的红葡萄酒来说，相对的低温有利于保持葡萄酒的水果味，但是那些酒体适中或者饱满的红葡萄酒来说，就不用保持低温了，只要在室温的情况下饮用就可以了，室温通常是16到18度。

The results show t hat yttrium exists as the form of compound (Al2Y) in AZ31 magnesium alloy, and dystectic Al2Y as the heteromorphic nucleation emerges firstly in the cou rse of alloy precipitation, which refines the alloy's microstructure and obviou sly improves the mechanical properties at room and high temperature. The average grain size of AZ31 magnesium alloy containing Y is reduced by 35.82%. Tensile s trength, yield strength and elongation percentage reach 212 MPa, 147 MPa, and 7. 5% at room temperature respectively, and 117 MPa, 98 MPa, and 10.2% at 200 ℃ re spectively.
