然而它们的导热系数的研究还相当欠缺，尤其是二甲氧基甲烷及其与柴油混合物的导热系数研究基本上没有人做过。

When the cost coefficients are fuzzy, the total assignment cost will be fuzzy as well. The Yager's ranking method is utilized to transform the fuzzy cost coefficients into crisp value, then the firm's optimal policy can be determined via the classical Hungarian method.

当指派人员执行各项工作的成本系数为模糊数值时，厂商的总指派成本亦为模糊数值，本研究的构想乃在於利用Yager 的模糊数值排序法，先将成本系数的模糊数值转换为明确数值，之后再利用传统的匈牙利法进行求解。

To study the effect of laser flux on impulse coupling coefficient during the interaction between hydrogen fluoride laser and aluminum at air ambient and in vacuum, respectively, by changing laser spot size on the aluminum target, the relationship between impulse coupling coefficient and laser flux is obtained, which are compared with the interaction between CO2 laser and aluminum.

为了研究激光功率密度对氟化氢激光与铝靶相互作用过程中冲量耦合系数的影响，分别在大气和真空中，用聚焦后的激光烧蚀铝靶，通过改变聚焦到铝靶的光斑大小，得到冲量耦合系数和激光功率密度的关系，并将该实验结果与CO2激光和铝靶相互作用的实验结果进行比较。

The introduction of extended corresponding state parameter θcan reflect effectively hydrogenolysis on water at the region of high pressure and low temperature and improve the precision of the second virial coefficients of water and humid air.

第4个参数的引入有效地反映了水在低温高压区氢键缔和的影响，改善了水和湿空气第二维里系数在整个温度区的精度，与ASHRAE的研究项目提供的湿空气第二维里系数数据吻合较好。

On the basis of these results, the relations of total-pressure recovery coefficient or flow coefficient and flight mach number, angle of attack and the second movable wedge angle of the inlet have been founded by hypersurface fitting, then the mathematical model of the inlet is established.

根据流场计算结果并利用超曲面拟合方法建立了进气道总压恢复系数、流量系数与飞行马赫数、进气道攻角及二级可调斜板角度之间的关系，由此得到了二元混压式超声速进气道数学模型。

In this paper, a high order accuracy difference method is presented for solving unsteady convection diffusion equation by using Implicit Perturbation Finite Difference scheme.

本文利用摄动差分思想，对定常对流扩散方程中的空间微商系数进行摄动展开，展开幂级数系数通过消去摄动格式修正微分方程的截断误差项求出，由此获得方程的隐式摄动差分格式，将此方法应用于非定常对流扩散方程，并加以修正，得到该方程的修正隐式摄动差分格式。

In this paper, a high order accuracy difference method is presented for solving unsteady convection diffusion equation by using Implicit Perturbation Finite Difference scheme. Firstly, we use the steady convection diffusion equation, the constant coefficients of this equation are expanded to power series of grid-spacings, then the high-order Perturbation Finite Difference scheme is obtained by determining the coefficients of the power series. Put this scheme on unsteady convection diffusion equations and modified it, the IPFD scheme is constructed.

Serum levels of TIMP-l were gradually increasing with the progression of diabetic nephropathy.

在DM组和DNF组，TIMP-1水平与年龄正相关，相关系数r分别为0.4866(P.05)和0.6229(P.01)，两相关系数差异无显著性。

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.

交际能力和语法的关系应该是目标与途径的关系。
