The dual-optical tweezers system has been improved:(1) The resolution of force measurement reaches sub-piconewton level and the maximum force is extended to 40 pN;(2)The time response is speeded up to sub-millisecond scale;(3) The observation and detection means for fluorescence-labeled macro-molecule is set up.

改进了双光镊系统：（1）将测力分辨提高到亚皮牛顿量级，测力范围扩展到40 皮牛顿；（2）将测量的时间响应提高到亚毫秒量级；（3）具备了观测大分子水平生物对象的荧光观测手段和相应技术。

Thermodynamic process of direct aluminium extraction from aluminium sub-sulphide, which is unstable and easily decomposed into Al and Al2O3 at a low temperature, was analytically studied. The temperature, at which alumina, FeS and carbon react to form aluminium sub-sulphide in different pressure, was evaluated with "Substance Gibbs' Free Energy Functional Determinant" method.

本文利用铝的低价硫化物在高温下存在，低温下不稳定容易分解得到金属铝的特性，从热力学角度引入"物质吉布斯自由能函数法"讨论在不同压力下，氧化铝、硫化亚铁与还原剂碳的反应生成低价硫化物的条件。

This method uses K-L transform to produce matrix of sample aggregate, get a low dimension sub space to describe the wrist bone's radiographs. Each image makes projection, and obtains one group of coordinate coefficients. The coefficients indicating the position of this image in sub space can be discerned the image feature.

该方法通过对由中指骨组成的训练样本集的产生矩阵做K-L变换，用一个低维子空间来描述中指骨X光图像，每幅图像向其作投影，并获得一组坐标系数，这组系数表明了该图像在降维子空间中的位置，能较好地表征该幅图像的特征信息。

Physical model of three-dimensional half axis rotor of 110 MW air inner-cooled turbo-generator was established, which included the rotor end, axial ventilation ducts and sub slot ventilation ducts. The rotating turbulence flow field was simulated numerically based on the finite volume method. The air velocity and flow rate distribution characteristics of the rotor end, axial ventilation ducts and sub slot ventilation ducts were analyzed.

建立110 MW空内冷汽轮发电机转子冷却通风道一个槽(包括端部、轴径向及副槽)的半轴向段三维物理模型，并基于有限体积法对该物理模型进行旋转湍流流场数值模拟，分析了端部、轴向段和副槽通风段的空气速度、流量分布特点。

I Group A: tenders offered by domestic tenderers meeting the criteria set forth in sub-clause 29.1 hereinabove and by joint ventures meeting the criteria set forth in sub-clause 29.2 hereinabove; and

甲组：国内投标者的标书，满足上述的标准；和合资投标者的标书，满足上述的标准

The production is completed mainly under a sub-contract system. About 90% of the manufacturers produce hosiery products in cooperation with their sub-contractors.

生产活动的进行主要还是以外包制度为主，约有90％的厂商是透过外包分工合作的方式进行织袜生产的运作。

The system of interdependency, a "tactic" system, is divided into two sub-systems: parataxis and hypotaxis; the logico-semantic system is divided into two sub-systems: expansion and projection.

前者属于一种排列系统，可分为并立和主从两个子系统；后者则可分为扩展和投射两个子系统。

The idea of digital ideograph of an abstract of the image related to sub-block was made with the function of Hash, and a digital watermarking encrypted, which can show whether the sub-block changes or not.

该水印是根据图像子块内容自适应生成的，图像子块内容如果有了显著变化，就会在水印中表现出来。

This period shall be deemed to commence on the date for payment specified in Sub-Clause 14.7 , irrespective in the case of its sub-paragraph (b of the date on which any Interim Payment Certificate is issued.

延误期应认为是从第14.7款规定的支付日期开始计算的，而不考虑期中支付证书颁发的日期。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
