Novel chitosan derivative with long alky groups as the hydrophobic moieties and carboxymethyl groups as the hydrophilic moieties was synthesized. The chemical structure of N-octyl-O, N-carboxymethyl chitosan was characterized via FTIR, 1H NMR and elemental analysis. The physical properties were analyzed with wide angle X-ray diffraction and differential scanning calorimetry.

以天然可生物降解的壳聚糖为原料，通过在壳聚糖6位羟基上引入羧甲基，在2位氨基上引入疏水烷基链，制得N-辛基－O，N-羧甲基壳聚糖两亲性衍生物，分别用FTIR、1H NMR和元素分析等技术对其结构进行表征，用广角X射线衍射和差示扫描量热法对具物理性质进行分析，并考察其在各种溶剂中的溶解性能及其对难溶性药物的增溶能力。

By extending the concept of MBE technique and employing the uniform buffers to separating the sample electrophoresis, the zone electrophoresis was developed. The isotachoporesis technique is based on the separation in a discontinuity form between two buffer solutions and results in separation of samples. The isoelectric focusing is a method that concentrates the ampholyte sample by the pH gradient introduced in the background ampholytes.

区间电泳法以移动边界电泳法作为基础的技术，其在系统环境充满均匀的缓冲液进行分离；等速电泳法则利用两缓冲液进行不连续分离之技术；等电点聚焦电泳法则利用背景溶液建立出pH值梯度，双性电解液样品因其位於等电点所受库伦力为零而聚焦於此。

Methods Sequence specific primers-polymerase chain reaction was used for the detection of genotypes and alleles of rs3850641 A/G loci in OX40L gene in 187 PACS cases (≤55 years) and 138 controls. Diseased vessel numbers and stenostic severity integral by coronary arteriogram and serum levels of sOX40L, C-reactive protein and vascular cell adhesion molecule-1 (VCAM-1) by enzyme-linked immunosorbent assay and nephelometry were measured. The relationship between OX4OL gene variants and PACS risk, SSI as well as plasma levels of three cytokines were analysed.

采用聚合酶链反应－序列特异性扩增技术检测187例年龄≤55岁、早发急性冠状动脉综合征患者和138例冠状动脉造影正常者rs3850641位点A/G变异的基因型、等位基因及其分布频率；采用冠状动脉造影测量病变血管支数和狭窄程度积分；应用ELISA法测试血浆sOX40L、血管细胞黏附分子(VCAM-1)；应用散射比浊法测试血浆C反应蛋白水平；分析OX40L基因变异与ACS风险、冠状动脉病变程度和血浆3个细胞因子之间的关系。

The legal level of the financial transfer and payment law should assort with the level of relevant laws.

财政转移支付法的法律位阶应当与相关法律的位阶保持协调。

This is a conversation between a journalist and Chinese attache sent to Franch.

这是一位记者采访中国驻法使馆的一位官员的谈话。

Fast Fourier transformation and autoregressive model estimation, are the most common methods used in the frequency domain analysis. The fluctuation in the highfrequency bands are mediated by parasympathetic control, whereas the fluctuation in the low frequency bands are mediated by both sympathetic and parasympathetic nervous systems. The origin of the fluctuation in the very low and ultra low frequency ranges are less obvious.

频域分析法一般是利用快速傅位叶转换或自动回规模型估计法，高频处的变异是由副交感神经系统调控，低频处的变异则是由副交感神经系统共同调控，至於极低频处与超低频处的变异，其原因尚待厘清。

"I'm not very good, but I know I have good potential," said Bert, a center fielder who last June became the first Frenchman selected in the major league draft."I don't have enough experience in baseball to be good."

Bert去年六月成为第一位在大联盟选秀会上被选中的法国人，这位中外野手说："我表现的不是很好，但是我知道我有绝佳的潜能，我只是缺乏经验而已。"

Birth process diagram combined with cephalic presentation score has very important role in the the recognise of head-position difficult labor and the selection of the mode of labor.

产程图结合头位分娩评分法，对头位难产异常产程的早期识别及选择恰当的分娩方式上具有重要的指导意义。

According to the inner or outer tolerance the algorithms for maximizing the forward-step by maintaining a constant tolerance are provided by the chord line or tangent line respectively.

建立了复杂曲面球头铣刀三坐标数控加工刀位计算模型，根据正负允差的不同要求，分别给出了弦线法和切线法自适应步长的刀位点生成算法。

However, he was subject to strife of other senior artisans. Claude Miniyaer did not give up his enthusiasm to research on jewelry craft. Minister Mazarin called on artisans to try for new gem polishing method. Most craftsmen held the traditional concept of polishing most precious gold and pearl jewelry, while Claude Miniyaer had realized the importance of the trial and joined with several craftsmen to research on combing different gem polishing ways. By working out a new gem cut-rose cut, they discovered unique features of diamonds, thus started the diamond era.

克洛德·米尼亚尔并未因此而放弃对首饰制作的热心钻研，当路易十四的朝廷大臣马萨林征集工匠试验新的宝石琢磨法时，大部分工匠还只停留在对传统观念中最贵重的黄金和珍珠首饰大加修饰之上，克洛德·米尼亚尔却感觉到了试验的非比寻常，他恳请加入其中，和另几位工匠开始对宝石进行不同刻面相结合琢磨法的尝试，他们的努力发掘了钻石从未被发现的特性，于是，宝石玫瑰形琢磨法问世了，一个大放异彩的钻石时代也就从这里开始。

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。
