The research of the characteristics of biology and the osteogenic and adopocitic induction are comparatively mature, showing many biological characteristics such as adherence, plasticity, heterology, self-renewal, rapid clone formation and transplantation. Adherence combined with density gradient centrifugation method is widely used in the isolation and purification of BMSCs.

骨髓间充质干细胞现阶段研究方向主要包括生物学特性、诱导分化和调控机制等内容，对其生物学特性和成骨成脂诱导方面研究比较成熟，在培养分化过程中展示出贴壁性、可塑性、异质性、自我更新能力、快速形成克隆能力、可移植性等生物学特征，贴壁法联合密度梯度离心法在骨髓间充质干细胞的分离、纯化过程中被广泛采用。

Based on the comparison of proposed basic topologies, Hypercube, as a popular used topology in networks, has a lot of advantages such as simple routing algorithm, small diameter and average number of internode distance, high fault-tolerance and so on. On the other hand, the network nodal degree which is logarithmically proportional to the number of network nodes limits the Hypercube network population most. So a class of hierarchical topologies are proposed to remedy this weakness of Hypercube and keep most of the advantages of Hypercube, such as CCC , HHC and deCube and so on.

基于对所提出的基本互连网络的性能比较，超立方体网络作为一个得到普遍研究的网络拓扑结构具有很多的优点，比如网络的非常简单的寻路算法，很小的直径和网络平均节点距离，高容错能力等等，但非常遗憾的是超立方体的缺点是超立方体的节点度随着网络规模的增加而成对数关系增加，从而限制了此网络的应用规模，大大地掩盖了它的诸多优点，所以人们提出了一类分层网络结构来弥补超立方体的不足同时最大限度地利用其优点，包括CCC，HHC以及deCube等。

By taking use of self-adaptive searching algorithm, optimal parameters of Incomplete Beta Function can be acquired, thereby obtaining the corresponding optimal transform curve. In this paper, Incomplete Beta Function is applied in contrast enhancement of container cargo inspection image, and the advantages of this function are well illustrated by comparing the experimental results.

Tubbs将图像增强处理中几种常用的非线性变换函数，表示成了一个归一化的非完全Beta函数，通过自适应搜索算法可以确定Beta函数的最佳参数，从而确定了相应的最佳变换曲线，将该函数应用于集装箱检测图像的对比度增强，通过对实验结果的比较，说明了该变换函数的优越性。

The first Jacobite writer on their rite is James of Edessa (d. 708), who wrote a letter to a priest Thomas comparing the Syrian Liturgy with that of Egypt.

第一詹姆士派作家对自己的成年礼，是詹姆斯edessa （四708 ），他写了一封信给一名牧师托马斯比较叙利亚礼仪中，与埃及的。

This paper simplifies the huge power system to be a linear circuitry by only the installation of Phasor Measurement Units on some buses to measure the voltage and current vector. Under Kirchhoff's law and Ohm's law, the conditions of inter-connected buses are calculated and further at the operation of whole system. Moreover, the understanding of electrical tide distribution is more understood and enable the power station workers monitor instantaneously and make comparison of operation frequencies at each area to monitor if the low frequency oscillations.

本论文系将庞大的电力系统想像成一个线性的电路系统，将某些汇流排装设同步相量量测单元，量测其电压、电流相量，藉由Kirchhoff's Law与Ohm's Law推算其相连接的汇流排的状态，进而了解整个系统运转时，电力潮流分布情形，提供电力公司人员作即时的监视，以及对各地区域的系统运转频率作同步比较，监视系统是否有低频振荡的情形产生。

OBJECTIVE: To compare the difference on the frequency of apoptosis induced by choline and folic acid deficiency in lymphoblast cell lines from breast cancer patient carrying BRCA1 genetic mutation and healthy control.

目的： 比较携带BRCA1基因突变的乳腺癌患者与正常人成淋巴细胞株对胆碱(choline chloride，CC)与叶酸(folic acid，FA)缺乏诱发细胞凋亡的差异。
