马来语既是马来西亚的国语,也是官方语言,无论是中学还是小学,马来语都是学生必学的科目。然而,不管是眼前的考试,还是未来的升学或就业,学习马来语一直是华裔小学生面对的难题。本研究主要分成三个部分。第一部将解释并探讨SALAK教学法如何提升华裔小学生在马来语书写方面的能力。在现有制度下,马来西亚并没有太多关于如何提升马来语书写能力教学的华语版论文、研究报告甚至是参考资料。而笔者选择此研究题目主要是希望能通过此研究而提升自身的教学质量,从而让其他执教中的导师们受惠。在文献综述里,笔者主要将国内外与如何提高书写能力书写有关的论文和期刊等做一个综述。研究方面,则选择了行动研究方法,这包括了文献探讨、资料收集来作为研究的根据,并对尚任职的华小校长、老师、补习老师进行访问,以从不同的层面,不同的角度,用更客观的观点来分析现在的华裔小学生所面对的马来语书写问题,进而想出适当的方法来提升他们的马来语书写能力。第二个部分则是对华裔小学生的马来语书写教学的问题和所存在的问题的归因做一个现状分析。再从华裔小学生的书写表现以及教师教学表现方面来展现出SALAK法的实践成效。第三部分为提升华裔小学生马来语书写教学质量的四个建议。其一,加强书写课的内容与现实生活的联系;其二,教学内容方式要更加灵活多变;其三,善于借助阅读提升书写的能力及技巧;其四,激活华裔小学生对马来语书写的兴趣。虽然马来西亚的马来语书写教学法的研究不少,但是仍以马来语为媒介语的居多,而以华语为媒介语的几乎为零。此研究除了更针对性,更深入的对华裔小学生所面对的问题提出建议,甚而也包括将现有最新的课程纲框架的问题和难题也纳入此研究的范围,并提出合时宜的建议,务确所总结的论点是于时并进的。

We use the method of device simulation to study the losses and influences of geminate and bimolecular recombinations on the performances and properties of the bulk heterojunction organic solar cells. We find that a fraction of electrons（holes）in the device are collected by anode（cathode）. The direction of the corresponding current is opposite to the direction of photocurrent. And the current density increases with the bias increasing but decreases as bimolecular recombination（BR）or geminate recombination（GR） intensity increases. The maximum power, short circuit current, and fill factor display a stronger dependence on GR than on BR. While the influences of GR and BR on open circuit voltage are about the *** studies shed a new light on the loss mechanism and may provide a new way of improving the efficiency of bulk heterojunction organic solar cells.

由于GRACE卫星数据解算的时变重力场模型中高阶位系数存在误差,这些误差在重力异常图中表现为南北向的条带噪声,在应用GRACE时变重力场数据时必须进行滤波.本文在空间域引入了一种有效消除GRACE时变重力场条带噪声的平滑先验信息方法,并将其与目前常用的高斯滤波和去相关误差等滤波方法分别应用于合成的质量变化趋势数字模型,检测不同滤波方法消除条带噪声的能力及其对真实信号的影响.滤波结果显示,与目前常用的高斯滤波和去相关误差滤波器相比,本文滤波方法在有效移除条带噪声的同时,具有有效信号幅度衰减小、有效信号形变小以及保存了更多的短波长细节信息等优势;此外,统计结果显示,本文滤波结果在信号最大值、最小值以及残差均方根等方面均与模拟真实信号最为接近.相比300km高斯平滑和组合滤波结果,有效信号振幅的极小值和极大值分别提高了约18%和6%,残差均方根分别降低了25%和33%.说明本文滤波方法移除GRACE相关误差的同时,在保留有效信号方面具有明显的优势.

In raw meal calcination process, there are three conditions, that is easy calcination condition, difficult calcination condition,and abnormal condition, and abnormal condition often happen because of varying material properties. Thus the pipe between preheater C5 and kiln rotary was blocked because the outlet temperature of preheater C5 is greater than the maximum value. To overcome above the problem, an abnormal condition controller integrated with fuzzy improved ELMAN network and Q learning has been proposed. The abnormal condition controller has been successfully applied to the actual industry process. Practical applications show that this abnormal condition controller has high potential in process control and can be applied to the other complex industries.

研究了人工分子伴侣复性体系中各种因素对溶菌酶复性效果的影响。当缓冲液浓度为23 mmol/L、pH值为8.1、以半胱氨酸为二硫键重排剂时,对人工分子伴侣辅助复性效果较佳。人工分子伴侣体系(CTAB、β-CD和Cysteine)的复性率比只加Cysteine的体系提高约40%,比添加β-CD和Cysteine的体系提高约20%。同时发现当溶菌酶浓度较高时,增加盐酸胍浓度可以提高蛋白质的复性率。
