摘 要：运用图形矩阵变换原理和矢量运算法则，推导出了立铣刀周铣过程中刀具切削刃上任意点相对于工件运动的轨迹方程，在此基础上构造出一种基于工件网格划分的三维表面形貌仿真算法，并给出了相应的仿真算例。

Although do the visitant that the advertisement bring on the Google may have no Overture of many, but the press of Google click to pay its expenses to correspond to also want a little bit low.

The weak formulation permit is satisfied not point by point, finite element method balances only at node neighborhood, in unit balance is not required, in analytical method single check from infinite series does not satisfy the equation, but infinite number of points satisfy the equation, and then the weak formulation of dual system of Hamilton equations was educed.

基于基本方程和边界条件的弱形式，给出相应的广义变分和不同形式的有限元所采用的弱条件，说明弱形式允许不是逐点满足，有限元法只在节点邻域平衡，在单元内不要求平衡，解析法用无穷级数中单取一项也不满足方程，也是无穷多项在积分下满足，进而导出对偶体系弱形式哈密尔顿方程。

The former being solved by the boundary point methool,and the latter constructed by the analytic way,on natter whetter the problem is defined in finiter or infinite region,and steady or transient .

将微分方程的非齐次问题解化为相应齐次问题解与某个非齐次特解之和，前者用边界点法计算，后者则通过解析法来构造，无论是有限域或无限域、定常或非定常问题，本文方法都能得出可靠有效

Some key algorithms were researched here: a "cut-and-sew" algorithm was presented here to resolve the reconstruction problem of adjacent section contour lines which different from shape and polygon vertex count; a random polygon triangulation algorithm based on CDT was studied to resolve the modeling problem of complex geological model with stones and holes inside; a grid-constraining algorithm of judging whether a point is in a polyhedron was studied here to construct the corresponding geological block model which constrained to wire frame model.

研究了构模过程中的若干关键算法：提出"切开-缝合"算法，解决了形状和顶点数目差异较大的相邻剖面轮廓线重构三维形体模型问题；研究了基于约束Delaunay三角剖分的任意多边形三角剖分算法，解决了含夹石或孔洞的复杂地质体构模问题；研究了判断点在多面体内的网格约束算法，以线框模型为约束构建了相应的地质块段体模型。

Results: At each examination tine, rADC in infarct core was lower than normal. Within 3 days after MCAO/R, rADC in infarct margin was lower than normal, and 7 days later, rADC equaled approximatively with normal.,and even was higher than normal.

但是，无论是在梗死灶中心还是边缘，TMS组的rADC值均比相应时间点的假刺激组rADC值高；两组内，梗死边缘的rADC值均比梗死中心的rADC值高。

For serviceability, the displaced shape, which storey drift ratio of the floor level at point of contraflexure on the initial mode of lateral displacement is equal to limit of the storey drift ratio, may be seen as target displacement mode. Based on the target displacement mode of frame- shear wall structure in the serviceability performance level, the equivalent parameter can be obtained.

对于使用良好性能水平，将侧移曲线上反弯点对应的楼层处的层间位移角刚好达到相应限值时的侧移曲线作为目标侧移曲线，据此计算等效单自由度体系的等效参数以及原结构的基底剪力和各质点的水平地震作用。

The main point for our purposes now, however, is the fact that theories and philosophies of education arise as answers to these substantive questions and, apart from conceptual or definitional preliminaries like the above, consist of and are distinguished by their answers to them.

然而现在，我们目标的主要点在于，事实上有关教育的理论和哲学是作为这些实质性问题的答案出现的，并且除了象以上概念上的或明确的预备，它们通过相应的答案组成并被区分开来。

By the cooperation of 8-MOP/UVA, the photoaging-characteristic biological markers of the dermic fibroblasts in vivo and in intro were changed as follows:① with a permanent switch of mitotic to stably postmitotic phentypes, fibroblasts displayed growth suppression and morphological changes of cell senescence;② increasing expression of SA-β-galactosidase;③ increasing expression of p16 protein;④ continuous up-regulation of mRNA of MMP-1 and MMP-3, while the protein of TIMP-1 was only slightly induced;⑤ high levels of the 4977bp deleted mtDNA accumulated in dermis and cultured fibroblasts, and large accumulation of a A→C base transversion of 414 position of 〓 of human mtDNA control region for replication of cultured fibroblasts also.

2.8-MOP/UVA作用下，体内外真皮成纤维细胞生物学特性出现具有光老化特征性的改变：①细胞由具有分裂活性的分裂表型转化为不具有分裂能力的分裂后表型，形态学出现细胞衰老的相应改变；②SA-β-Gal表达增加；③p16蛋白表达增加；④MMP-1、MMP-3 mRNA持续表达而TIMP蛋白表达仅被轻微诱导；⑤mtDNA 4977bp缺失大量累积，培养成纤维细胞mtDNA复制控制区〓片段414碱基迅速出现大量A→C的点突变。

A mixed linear model approach and its software were used to detect QTLs with main effect, QTLs involved in digenic interactions and Q×E interactions.
