It includes hardware equipments and foundational theory of the image digitization. This paper expatiates on some digital image processing technologies that the inspecting system may apply to the research and analysis of the collected glass-crack image. Using neighborhood average method and median filter retrains the image noises and make the image edge smooth. Then protract the histogram of the gray image, get the threshold of this image, utilize the threshold method and gray-level slice method to get a binary image, and detect the image edge. Finally calculate the area and perimeter of the glass-crack image, and use the circularity to judge whether this image is a glass-crack image.

本文重点阐述了研究和开发这套玻璃瓶裂纹检测系统所应用到的一些数字图像处理技术，并应用这些技术和方法对采集的裂纹图像进行了处理和分析：应用邻域平均法和中值滤波法来抑制图像的噪声，使图像的边缘平滑；然后绘制出处理过图像的灰度直方图，得到该幅裂纹图像的阈值，利用阈值法和灰度级切片法对裂纹图像进行二值化处理，得到其二值图像，并对图像进行了边缘检测；最后计算出裂纹图像的面积和周长，利用圆形度指标来判断该图像是否为裂纹图像。

In this dissertation, the genetic algorithm is discussed in detail. In order to improve the convergence of GA, considering that it is important to choose the probability of crossover and mutation , new p〓 and p〓 were varied depending on the fitness values.

该方法在遗传模式得到保证的基础上，加快新个体的产生速度，所构造的交叉算子和变异算子随适应值自动变化，对远离最优值的个体采用较大遗传算子值，对接近最优值的个体采用较小遗传算子值，提高得至撮优解的概率。

Dose type used to revision of media"s pH, peptonization intensity of media, temperature, high temperature and pressure pasteurization are factors of media"s pH; Sterilizing time, volume of media, content of pledget, NaCl,CaCl2,sucrose and active carbon can Iead to the lowing of MS medias pH after high temperature and pressure pasteurization; The influencing trend and extent of every factor is different obviously.8 Study on media simplification experiment.

影响培养基pH值因素的研究培养基pH值校正试剂、胨力强度、温度、高温高压灭菌都是影响pH值变动的重要因素；灭菌时间、培养基体积、以及培养基内脱脂棉、NaCl、CaCl_2、蔗糖及活性炭等的含量等，能在高温高压灭菌过程中引起MS培养基pH值下降；各因素对pH值变动的影响趋势和程度明显不同。

ConclusionThe factors that significantly influenced L* value in facultative parts were exposed time and the frequency of using sunscreen, factors that influenced b* value in facultative parts was the frequency of using sunscreen, factors that influenced L* value,a* value and b* value in constitutive parts was skin phototype.

对曝光部位L*值影响最大的是日光曝露量和使用防晒霜频率；对曝光部位b*值影响最大的是使用防晒霜频率；对非曝光部位L*值、a*值和b*值影响最大的是皮肤光类型。

In order to compare the results for the three different die gaps, the ratio of the two principal strains is introduced, being min/max, where max and min are the major and the minor principal strains, respectively. Hosford and Caddell [5] have shown that if the absolute value of is greater than a critical value, wrinkling is supposed to occur, and the larger the absolute value of , the greater is the possibility of wrinkling.

为了比较三种不同模具间隙的结果，两种主要张力的比率被介绍-是最小值/最大值，这里最小值/最大值是主要的和次要的张力，分别的， Hosford and Caddell [5] 显示如果他的绝对值比临界值大，起皱应该会产生，越大的绝对值，则越大的起皱产生。

In this paper,a new algorithm is given by means of the complexification of the knots,i.e. the node in the plane is considered as a complex point,the vector as a complex vector,and then based on the construction of vector valued Thiele type rational interpolants and the backward three term recurrence relation for vector valued continued fractions,the recursive algorithm is obtained by appropriate transformation.

文章利用插值型值点复数化的方法讨论并给出了二元向量值有理插值的一种新算法，即把平面上的插值结点视为一个复数，所对应的向量视为一个复向量，使用一元Thiele型向量值有理插值公式的构造方法和向量连分式的向后三项递推关系式以及适当的变换，最后导出了这种递推算法。

In this paper, thereare four sections. In the first section, we introduce the basic theory. Inthe second section, we give out the recent main results of multivariateLagrange interpolation. In the third section, we get some theories ofno posed set of nodes from a kind of recursive method of constructingposed set of nodes for bivariate Lagrange interpolation, and we get akind of abnormal posed set of nodes for interpolation form the reversethought of that theory.

本文共分为四章，第一章介绍了有关多元插值的基本理论和方法，第二章讲述了有关多元Lagrange插值和多元切触插值的近期主要结果，第三章我们从有关适定结点组的添加曲线法考虑，得到了一些有关Lagrange插值不适定的结论，并从该结论的反方向思考，得到了一种非常规型插值适定结点组。

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。
