The primary goal to develop a new highly effective deicer is gained.

基本实现了开发新型除冰剂的初衷，达到了本课题的研究目的。

All of these aspects need to be improved.Considering the disadvantages of the two kinds of the deicers, great amounts of the science data are referred in the research experiment, by developing the main materials and the additives, a new kind of deicer: PAL is founded. Not only does PAL remain the advantages of the traditional deicer such as cheap materials and low freezing point:-43.8 C, but it has the character of CMA, low corrosion to steel and concrete.

针对上述除冰剂的缺点，本课题收集了国内外大量的相关科技文献，通过对主体物料和添加剂两方面的改善，寻找到一种新型除冰剂PAL，它既保留了传统除冰剂的优点，原料廉价易得，低冰点，可达-43.8℃；又兼有CMA的优点，对钢铁几乎无腐蚀，对混凝土无不良影响。

In image processing, method as follows will be introduced in this paper: a method combining image threshold iterative segmentation with threshold interpolation, edge detection operator Sobel and LoG, edge linking method using delation operator based on mathematical morphology, using boundary tracking and projection method in edge distill process. Through this method, measurement of wheelset will be met precision demand.

本文阐明了图像的分通道自动采集过程，以及对采集到的原始图像进行预处理过程，达到图像去噪声的目标，本课题采用了阈值分割中迭代阈值和阈值插值相结合的方法，Sobel算子、LoG算子边缘检测算法，基于数学形态学的膨胀运算子进行边缘断点连接以及目标提取中的投影法和边缘跟踪方法，使得提取轮对图像边缘达到测量精度的要求。

The delay differential equation is an important offshoot of modern applied mathematics.

结论时滞微分方程是现在应用数学的一个重要研究课题。

Deliquescence of calcium sulfite under various conditions including temperature,pH,dissolving time,stirring rate and initial quantity was investigated in experiment.

亚硫酸钙的溶解浓度对氧化速率有非常重要的影响，课题主要研究CaSO3的溶解特性，描述了CaSO3在不同条件下(温度、pH、溶解时间T、搅拌速度、初始加入量等)溶解量的变化规律，进而找出CaSO3的最佳溶解条件，以达到提高氧化速率及石膏的生成率，防止堵塞和结垢的目的。
