不值

The prediction results of excess Gibbs free energy show that its deviation from the experimental values is less than those of SH theory and the modified SHFH theory for most of thirty - five binary liquid mixtures, especially in solutions of fluorocarbons and hydrocarbons where SH and SHFH theory are not applicable.

对35个二元液体混合物的过量Gibbs自由能预测结果表明，预测值与实验值的偏差大多优于SHFH理论，特别是碳氟与碳氢化合物的溶液，对于这类溶液，正规溶液及其修正形式SHFH理论是不适用的。

In the process of degree reduction, two cases are considered respectively. One is the case without conditions of endpoints interpolations.

两种方法均考虑了不带端点插值条件和具有端点高阶插值条件的情形，并给出降阶Bézier曲线控制顶点的显示表示式。

The method is just like the QuikChange site-directed mutagenesis method except for its special primer. This pair of primers is composed of a long primer and a short primer which is central overlapped.Both of the Tm of 5\'sequence in long primer and Tm of 3\'sequence in short primer are above 66℃.The Tm of short primer is almost half of that of long primer.It is convenient to perform insertion or substitution mutation of DNA fragments larger than 20bp,In addition,it is highly applicable in research about the deletion mutation of DNA fragments larger than 2000bp.

我们实验室一直在寻找一种简单高效的可以用于基因的删除、插入及替代突变的方法，通过大量研究和实验发现，可以使用一种基于反向PCR原理，使用全新的引物设计的突变方法——&COP&突变法，该方法采用与QuikChange点突变法相同的操作步骤，其策略是设计一对中心重合的引物，长引物的5\'端序列和3\'端序列的Tm值均不低于66℃，短引物Tm值约为长引物一半，且与长引物中心重合互补。

The yield of neutral oil stocks (300℃~500℃) is 42.33%, the latent content of lube is about 90%, and they have the characteristics of low residue carbon, low sulfur content, light-colored, low acid number and less total and aromatic ring numbers.

中性油原料收率为42.33%，其中润滑油潜含量均在90%左右，且残炭值及硫含量不高，颜色浅、酸值小，结构族组成中总环数与芳香环数较小；光亮油原料收率为16.38%，其凝点较高，粘度较小，结构族组成中的烷基碳率较高。

These enzymatic haemostatic agents can be used to antagonize the side effect of hirudin. We take the batraxobin as an example to illustrate that the enzymatic haemostatic can antagonizes hirudin. Agglutination reaction occurred after the tubes containing hirudin were added with batroxobin , i.e., batroxobin can antagonize hirudin. In a canine model,, the reduction extent of TT and APTT in the test group was larger than that in the control group; the bleeding time was decreased obviously and it was shorter in the experimental group than in the control group at lh, 2h and 3h after hirudin injection, indicating batroxobin can antagonize the bleeding side effects of hirudin.

以巴曲停为例，加入巴曲停的水蛙素抗凝试管内又可发生凝集反应，而未加入巴曲停的试管内不发生凝集反应；犬动物模型显示，水蛙素实验组TT值、 APTT值明显低于水蛙素对照组，犬给予巴曲停后出血时间明显缩短，出血时间在滴注水蛙素后lh、2h、3h明显短于对照组(P.05)，说明巴曲停有拮抗水蛙素抗凝血的作用。

In this for, the expression uses the prefix increment operator, which as we know adds one to the value of val. After executing the expression , the for retests the condition . If the new value of val is still less than or equal to 10, then the for loop body is executed and val is incremented again. Execution continues until the condition fails.

在这个 for 循环中，表达式使用前自增操作符， val 的值加 1，执行完表达式后， for 语句重新测试条件，如果 val 的新值仍小于或等于 10，则执行 for 语句体， val 再次自增，继续执行直到条件不成立。

Because the author's forum does not have big website to be willing to recommend, look for a few Pr to be worth low website to undertake was linkinged so only with thickskinned, ah, just began to compare difficulty, because the website does not have PR value to also was not collected namely, general website does not wish to link, must hold to so, small website also is a website, many somes of link is many road, who knows reptile is met circuit climbs over from which.

因为笔者的论坛没有大网站愿意推荐，所以就只有厚着脸皮去找一些pr值低的网站进行链接了，呵呵，刚开始比较困难，因为网站即没有PR值也没有被收录，一般网站都不愿链接的，所以一定要坚持了，小网站也是网站，多一些链接就是多一条道路，谁知道爬虫会从哪个线路爬过来呢。

After the linear pointing correction, the surveying region is divided into spherical Delaunay triangulations, and the whole smooth pointing correction surface is produced by using the high-accuracy generalized extended interpolation approximation method.

提出了一种新的基于广义延拓插值的射电望远镜指向误差修正模型，在线性修正模型的基础上对观测域进行球面的Delaunay三角剖分，利用高精度的广义延拓插值逼近方法生成不分项的整体分布曲面。

They are therefore approximations and cannot be used for highly critical flow or pressure drop calculations.

因此这些数据只是大致的数据，不能用作高流量临界值或压降估计值。

Whether the ceteris paribus effects are reliable or not depends on whether the conditional mean assumption is realistic.

在其它条件不变情况假定下我们估计出的x对y的影响值是否可信依赖，完全取决于条件均值零值假设是否现实。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
