The pattern of camber die-drawing are optimized. The physical innate character of drawing with camber die is analyzed thoroughly. For the first time, the periodical relation between the limit drawing coefficient and the large longitudinal stress in dangerous section is established. Furthermore, the rationale to judge limit deforming degree is developed. Then, the limit drawing coefficient of drawing with camber die is proposed. Based on the criterion that the large stress in flange is smaller than that of limit value, the formula of drawing with camber die without wrinkles is deduced.

对拉深凹模的型式进行了优化；深入地分析了曲面凹模拉深成形的物理本质，首次定量地确定了极限拉深系数与危险断面最大径向应力的关系，提出了判断极限变形程度的依据，分析了极限承载能力，建立了曲面凹模拉深的极限拉深系数的表达式；以凸缘切向最大压应力小于凸缘切向压应力临界值为准则，推导出了曲面凹模拉深不起皱的理论表达式。

The classic iterative ones need special characters of the coefficient matrix; CG has over linear convergence, but the coefficient matrix is positive definite; Krylov subspace ones can deal with non-symmetric linear systems, but sometimes it must face"collapse"problems.

经典迭代法的收敛需要由系数矩阵的一些特定性质来保证；共轭梯度法具有超线性收敛性，但是系数矩阵必须是正定矩阵；Krvlov子空间法可用于非对称矩阵问题，但可能出现崩溃现象。

The results showed that in the four rehabilitated forests, the previous month's soil moisture content had stronger effects on the current month's soil moisture content in 0-40 cm and 20-40 cm layers, but had lesser effects on that in 0-10 cm layer. The soil moisture content in 20-40 cm layer was mainly affected by current month's precipitation, while that in 0-10 cm layer was mainly affected by current month's evaporation. The correlation coefficient between current month's precipitation and soil moisture content was the largest in pure Liquidambar formosana plantation, and the auto-interrelation coefficient of soil moisture content was larger in mixed forests than in pure L. formosana plantation.

结果表明：研究区各重建森林前一个月的土壤含水量对当月整个土壤剖面(0~40 cm)平均土壤含水量和当月20~40 cm土层土壤含水量具有较强影响，对当月0~10 cm土层土壤含水量的影响较小；研究区各重建森林20~40 cm土层土壤含水量主要受当月降水量的影响，0~10 cm土层土壤含水量主要受当月蒸发量的影响；在4种森林重建模式中，枫香纯林当月降水量与当月土壤含水量的相关系数最大，混交林模式土壤含水量的自相关系数大于纯林模式。

Thus we can assert that the difference between global and local squeezing parameter doesn't vanish is a sufficient criterion for the entanglement.

由这个关系，我们可以得到总体压缩系数与局域压缩系数的差值不为零可以作为子系统间存在纠缠的充分条件。

By means of statistical inference as well as hypothesis test method, it is determined that the variables of compressive stress and shearing stress are of Extreme-value Ⅰ Distribution and that the variables of frictional coefficient and cohesion coefficient are of Logarithmic Normal Distribution.

应用统计推理和假设检验方法分析得知，压应力与切应力随机变量呈极值Ⅰ型分布，摩擦系数与粘结力系数随机变量呈对数正态分布。

Among the four paper formation assessment methods, i.e., coefficient of variation, varience (S^2), M/K formation index, and modified all-pairs score, the COV and look-through judgements are most affected by mean light absorbance. Under similar mean light absorbance renditions, all four methods gave similar results.

吸光度变异系数、影像灰阶变异数(S^2)、M/K交织指数及目测修正成对评分法四种纸张交织评估法中，变异系数及目测法受纸样平均吸光度之影响较大，而平均吸光度相当时，四种评估法所得之结果相近。

The range of Simple match coefficient was from 0.5877 to 0.9868 and the range of average was from 0.6732 to 0.7653,with the total average of 0.7237.The result indicated that the soybean population was with lower genetic variation.

品种间的遗传相似系数变化范围为0.5877～0.9868，平均值变化范围为0.6732～0.7653，总体平均值为0.7237，遗传相似系数较高，说明材料间遗传变异较小。

The results show that the addition of polypropylene fiber can reduce the dry shrinkage coefficient and thermal shrinkage coefficient of cement stabilized macadam effectively.
