Amukhin et al.,and convert it into an effective1D chain with particular distribution of equivalent coupling bonds.Then we use the single-electron Schrodinger equation to calculatewave functions of electrons in the chain by transfer matrix method,without using the assumption of Samukhin et al.On variable hoppingmechanism and critical percolation condition.From this calculationwe obtain the dc conductance directly from Landauer-Buttikarformula.

mukhin提出的多层次等级分形结构模型，将其简化为耦合键强度t具有特殊分布的等效一维链，舍弃前人假设的变程跳跃机制与临界渗流条件，从单电子薛定谔方程出发，用转移矩阵方法计算一维链的透射系数，再利用Landauer-Buttickar公式直接求出直流电导。

The resulting arc spline is shape|preserving, and has the same number of inflections with the original polyline;(2) The segment number of circular arcs is the same as that of data points.

这种算法具有以下 3个特点：(1)生成的圆弧样条曲线具有保形的特点；(2 )圆弧样条中圆弧的段数与型值点个数相同；(3)圆弧段之间的连接点不一定在插值的型值点上，这样就能用更多的自由度来控制拟合曲线的形状。

RESULTS:①Cytocompatibility of PEG-PLA-PGL membranes with HUVECs: The observation result of phase contrast microscopy showed that, endothelial cells planted on the PEG-PLA-PGL membranes began to attach and stretch after being planted 4-6 hours. Three days later, cells grew in colonies rapidly, after 5 days, colonies began to fuse and seemed like cobble-stone. The cells were shuttle or polygon in shape after passages.

结果：①人脐静脉内皮细胞与聚乙二醇-聚乳酸-聚谷氨酸三嵌段共聚物膜片的细胞相容性：相差显微镜下种植在聚乙二醇-聚乳酸-聚谷氨酸三嵌段共聚物膜片上的细胞4~6 h后即开始贴壁、伸展，3 d后细胞开始呈集落样生长，生长较快，5 d后细胞集落开始融合，呈现特征性的鹅卵石样形态，经多次传代后，细胞呈长梭形或多角形，与对照组相比无明显差异。

This paper deals with the leaf shape design of multi-leaf collimator used in 3-dimensional conform al radiation therapy.

讨论了三维适形放射治疗中的多叶组合光栅的叶片设计。

At first, the examples are given to explain a new method in signal processing, in which functions are defined from the viewpoint of multi-scale analysis. Then the authors present "coordinate heft separate" method, discover self-similar structure of points set on plain area; based on this self-similar structure, construct orthogonal complete 2-value function system of high-dimension simplicity; enrich and extend the theory and application of Rademacher function and Walsh function.

首先，举例说明在多尺度分析观点下，信号处理中某些函数定义的新方法；进而提出"坐标分量分离方法"，并由此发现了平面区域上点集坐标数值的自相似结构；在揭示了如此自相似结构的基础上，构造了高维单纯形上的正交完备的二值函数系统；丰富与推广了Rademacher函数及Walsh函数的理论及应用。

The space configuration of each vehicle is described by a 26-freedomed multi-body model.

用26个自由度的多刚体模型描述每节车辆的空间位形。

Archaeologists were impressed and puzzled by this map dated 2100 years ago because the level of mapping technology used in this map are comparable to modern maps, which are manifested by the high precision achieved in the mapping of rivers, and the representation of mountains and their peaks using conformal projection.

这幅2100多年前的古代地图，河流测绘的精确程度非常高，并且使用正形投影表示山脉山峰，其测绘科技水平已接近近代地图，这令人感到十分惊讶同时也不免产生困惑。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
