根据用户提供产品零件图绘制铸件图及模具图或三维数模，编制铸造工艺方案及热处理方案，试制模具、修模，指导生产过程并及时解决或反馈现场问题，对铸件进行检验或校正，研究存在问题并提出解决方案，直至产品合格并交货。

A thorough discussion is carried out, in which how to call conventions of VC and CVF and how to coordinate between them are given, alphabet string, multi-dimension array and derived type in combination with Fortran 90 are correspondingly set up in C/C++ functions, etc..

对此进行较为系统的探讨，包括VC，CVF的调用约定是如何规定的，如何在二者间进行协调，如何针对Fortran 90的字符串、多维数组、派生类型设置相应的C/C++函数参数等，并通过典型示例加以说明，为VC创建供CVF调用的Win32 DLL提供了操作指南。

The whole process of text representation were discussed — word segmentation, building stop words list, feature selection, weight computation and generating vector space. Aim at the influence of stop words, a list, which is fit for text categorization, is set up and makes the vector dimension reduce.

针对停用词对分类的影响，建立了适合文本分类的停用词表，使向量维数得到初步降低；对现有特征选择方法进行了介绍和对比，构造了一种适合支持向量机的特征选择函数——基于类内频率的特征选择函数。

A new solution method of implicit pressure, saturation and explicit mole fraction of components is presented here.

本文在对它求解时，提出了隐式压力、饱和度和显式组成的方法，它只需联立总烃和水的连续性方程，大大减少了隐式方法所需联立的方程组的维数。

Moreover, their mass fractal dimensions Df, calculated by bi-logarithm relation between setting rates and equivalent circle diameters, were 2.0972.801, and the Df value for granules in the 5th compartment was the highest one among them, indicating that the most compact granules were formed. The least compact granules were observed in the 4th compartment, and the granules in the 1st and 2nd compartments show close compactness. However, the highest average setting rate for granules was detected in the 1st compartment.

依据沉降速率-当量圆直径的双对数图计算出的各格室中颗粒污泥的质量分形维数Df处于2.0972.801之间，大小顺序为：第5格第3格第2格第1格第4格，表明第5格室中形成的颗粒污泥较为密实，而第4格室的密实程度最小，但密实的颗粒污泥并不一定意味着较高的平均沉降速率。

According to the fractal dimension, the disturbed distance between upper and lower fracture surfaces and the ratio of area contact (the proportion of contact area to whole area of fracture) of fracture, the random Brown Function is used to generate a rough-walled fracture with position-dependent aperture.

根据裂隙面分形维数、裂隙面位错值和裂隙面上的面积接触率，用随机布朗函数生成裂隙的开度分布。

a novel miniaturization bow tie rfid tag antenna is proposed based on the triangular sierpinski fractal microstrip.the port characteristics of the proposed antenna are presented by simulation.at the same time,the resonance frequency,the radiation pattern and the efficiency of the sierpinski tag antenna is given.the results of the simulation show that multiple frequency band can be obtained by varying the dimensions of the fractal structure.hence this kind of antenna can be used into the rfid tag antenna very conveniently.

摘 要：基于三角形sierpinski微带分形贴片，提出了一种新型的小尺寸领带结rfid标签天线设计。通过仿真，给出了该分形天线的端口特性，同时给出了该领带结型sierpinski标签天线的谐振频率、方向图以及天线效率。结果表明，采用不同维数的分形结构，可以实现多频段的工作特性，因而该天线可以很方便地应用于rfid电子标签中。

If the dimensionality of the data was two or three you would have plotted them as a scatter plots and identified how many classes are there.

如果数据的维数是两个或三个你会策划作为散点图他们，并确定了多少班在那里。

The results are as follows: 1 great changes have taken place in land use and landscape pattern from 1995 to 2000; the area of woodland, water and unused land has been reduced and that of grassland, cropland and construction land increased; 2 the advance of fractal dimensions, the diversity index and landscape fragmentation degree showed that landscape units became strongly fragmented; 3 the dominant degree of construction and unused land has changed little but that of meadow and water increased, and that of farmland and woodland decreased to some extent, which indicated that the trend of landscape pattern changed from cropland and woodland to meadow and water; 4 the changes of land use and landscape patterns near the road are obvious and it is urgent to strengthen eco_environment protection.

主要结果如下：①1995-2000年间，研究区土地利用变化显著，其中林地、水域和未利用土地面积下降，而草地、耕地和建设用地面积增加；②景观破碎化程度加剧，分维数、多样性指数和景观破碎度均增加；③建设用地和未利用土地优势度变化不大，耕地和林地的优势度减小，草地和水域优势度增加，表明研究区景观格局由耕地、林地向草地和水域转变；④交通干线附近的土地利用和景观格局变化显著，加强这些区域的生态环境保护与建设势在必行。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
