In the present paper, based on the thorough analysis and research of the mathematical model for the flow field and temperature field, the filling and solidification process of aluminous hub was successfully simulated by using ANSYS software.

本文以大型有限元仿真软件ANSYS为工具，在对铸造过程流场、温度场的数学模型进行深入分析研究的基础上，成功的模拟了铝合金轮毂类铸件低压铸造的充型凝固过程，并根据模拟结果对铸件可能产生的缺陷及部位进行了预测，完成了利用ANSYS软件来检测、校核模具设计和工艺安排的工作。

Accordingly, how to ameliorate and consummate these defects and deficiencies is discussed in the paper.

本文将就这些缺陷和不足，对如何完善提出建议。

Study difficulty means an abnormal phenomenon. the normal children of amentia sense organ, has not reached the required level complying with their intelligence in study grade yet although depending on the common school education.

学习困难是指那些感官正常又无显著智力缺陷的儿童依靠通常的学校教育，学习成绩尚未达到其智力所及水平而出现的一种现象。

The results of IR and XRD for ground cement components show that grinding aids accelerate breakage of chemical bonds especially of Si—O bond in C〓S mineral, enhance crystal lattice distortion, crystal defect and amorphism, thereby enhancing activity of ground materials.

助磨剂作用下磨细物料的XRD、IR分析结果表明：助磨剂加剧了物料的晶格畸变、晶格缺陷及无定形化，加速了物料结构中化学键的破坏，尤其是C〓S矿物中Si—O键的断裂，从而增加物料的反应活性。

But there are a lot of defects in amorphous silicon, therefore its application have been limited.

但是由于它含有大量的缺陷态，使其在实际应用方面受到了约束。

One thing you can do is challenge the thoughts that amplify your flaws.

可以去做的是挑战把你的缺陷扩大化的那些想法。

Cloning of the Schwanniomyces occidentalis α-amylase and high expression in S.cerevisiae.The E.coli / yeast shuttle plasmid YCEpl partial library of Schwanniomyces occidentalis DNA was constructed and α-amylase gene fragments were screened in Saccharomyces cerevisiae by amylolytic activity.Several transformants with amylolysis were obtained and one of the fusion plasmids has about 5.0 kb inserted DNA fragment.It contains the upstream and downstream sequences of α-amylase gene from S.occidentalis .

以E.coli/yeast穿梭质粒YCEp1为载体构建西方许旺酵母部分基因组文库，在大肠杆菌中扩增后提取混合质粒DNA，经电转化非缺陷标志酒精酵母 AS.2.1364，在YPDS平板(含1%葡萄糖和1%可溶性淀粉)上用淀粉水解活力筛选含水解淀粉的阳性转化子，从阳性转化子中分离重组质粒证实含5.0kb的插入片段，用α-淀粉酶基因两端序列设计的引物PCR扩增及扩增片段序列分析证实该片段中含有α-淀粉酶全部编码序列。

Then the interpolation method and analogue method can be used for calculating descaling temperature.
