Old Vs New Concepts 老概念新概念Body Line is parallel with bottom of pool.

新： 身体直线平行于池底老：此线与池底有一上翘的角度。

Hence only parallel rays are able to pass through this aperture and therefore as the reflecting object seems to be infinitely remote, there can be no perspective distortion and also magnification is independent of the distance to the lens.

因此，只有平行光线能够通过此孔径，因此，作为反映的对象，似乎是无限遥远，不可能有任何角度的扭曲和放大，也独立于距离镜头。

So this paper selects national debts as our studying objects. By using principal component analysis method to study the zero coupon yield curve, we find that the movement of the curve yield can be simulated by two factors mostly, that is parallel shift and rotation. Then we quantitative them and get "synthetic parallel shift" and "synthetic rotation".

因而，本文选择了国债作为研究对象，对国债的即期收益率曲线进行主成分分析的结果表明，收益率曲线变动的总体方差绝大部分来自于两个因子的贡献，即水平因子和倾斜因子，本文对这两个因子进行量化处理，得到"综合的平移"和"综合的倾斜"，并在此基础上建立了两综合因子法对债券组合的VaR估值模型。

Our methods and condition are suitable for the isolation and primary culture of rat gastric parietal cells.

此方法适宜于大鼠胃壁细胞的分离及体外培养，为体外进一步研究壁细胞的功能打下基础。

The ultra structural changes of nerve root arc the pathological basis of the function loss of the nerve root. The present model is more closer to the model of lumbar intervertebral disc herniation and stenosis of nerve root compression and it provides a basis for treatment of compression caused radicular pain and numbness in clinic.

神经根超微结构的改变是神经根失功能的病理形态学基础，此模型更接近于腰椎间盘突出和椎间管狭窄对神经根的压迫，为临床神经根性疼痛及麻木治疗的研究建立了可供参考的动物模型。

This payment method is currently only available to individual payee names; we can't offer it to businesses.

此付款方式，目前只适用于个别收款人名称；我们不能提供给企业。

This paper introduces the game theory and sets up, based on it, the choice model for the public transportation priority by identifying the function of the payoff and the muster of attendee and stratagem. In addition, it analyses the existence of NASH equilibrium, and puts forward the arithmetic of Iterated Elimination of Strictly Dominated Strategies in the general condition, the Integrated Strategies in the special condition and the flow chart of the model. At last, it verifies the feasibility of the model with the given example.

本文采用了博弈论的理论，通过对公交优先系统中参与者集合N、战略集合S和收益函数u的确定，建立了一种基于博弈论的公交优先技术方案选择博弈模型来量化方案选择问题；在此基础上分析了NASH均衡的存在性，并且给出了一般情况下的重复剔除劣战略和特殊情况下的混合策略两种模型求解方法以及公交优先技术方案选择博弈模型的流程图；最后通过算例分析，验证了博弈模型应用于公交优先技术方案选择的可行性。

With genomic DNA of Clostridium stercorarium as a template, a structural gene pel9A encoding pectate lyase was obtained by PCR amplification. The pel9A was cloned into pET28a to recombine an express plasmid pPel9A, and then the plasmid pPel9A was transformed into E. coli BL-21, expressed under the control of T7lac promoter at 37℃.

利用PCR技术从耐热梭状芽孢杆菌中扩增得到产耐热果胶裂解酶的结构基因pel9A，并将其克隆于表达载体pET28a中，最后将此重组质粒转化到受体菌E.coli BL-21中进行表达。

This Pentacle is fit for exciting earthquakes, seeing that the power of each order of Angels herein invoked is sufficient to make the whole Universe tremble.

这个五角星适用于引发剧烈的地震，看那每一个秩序天使的力量在此被召唤足以使整个宇宙颤抖。

The analytical method is always used due to the large amount of the objects and not very high accuracy of forecasting. A method based on the position and velocity derived from the mean orbit elements directly is given, which is to avoid the problem of singularity in calculating the periodic terms of orbit elements variation, thus the process and software can be simplified.

在已有分析法得到t时刻平均根数的基础上给出一种轨道预报方法，由t时刻的平均根数给出该时刻卫星的位置和速度，在此基础上将地球非球形引力摄动的周期项直接用卫星直角坐标的位置和速度分量表示，这样可以避免在计算轨道根数变化的周期项时出现的奇点问题，从而对根数的选择无特殊要求，可适用于各种轨道，简化预报程序和相应的软件，提高预报效率。

Methods: Five patients with parkinsonism or dystonia were assigned to general anesthesia using an modified endotracheal tube.

本实验依照人体实验之相关规定进行，五位患有帕金森氏症或肌张力异常的病人接受神经立体定位手术。
