That tenth of a point on the logarithmic pH scale actually means a roughly 30 percent increase in acidity.

因著海洋pH值从上个世纪8.2变为8.1，被称为有孔虫的微小生物壳的厚度变薄了。pH值是对数刻度，这0.1实际上就是酸度大致增加30%。

The article studied Eisenberg model, Forsman model, Dreyfus model, Bonnoto Bonner, Longworth, Vaughan model and Core-shell model. A BAB-triblock copolymer was employed as macromolecular model. Minimized Gibbs free energy relates the micellar structure parameters to parameters of the triblock copolymer quantitatively. Furthermore, it could be explained theoretically that the micellar diameter and the equilibrium aggregation number both decrease with ion content.

然后讨论了BAB型三嵌段模型、Eisenberg模型、Forsman模型、Dreyfus模型、Bonnoto和Bonner、Longworth和Vaughan模型与核-壳模型，并以BAB型三嵌段离聚物为模型大分子，建立了胶束特征参数与聚合物结构参数之间的定量关系，从理论上解释了胶体粒径和聚集数随离子含量的增加而降低的原因。

The last materials are primarily Lorica, with mesh cooling inserts.

The Arctic sky is special because it is one of the two places where the magnetic shield of the Earth opens up to outer space.

由于北极是地球上仅有的磁场壳对外太空开放的两个地方之一。

Generally the numerical stimulation on flow field and temperature field of shell distance is based on porous medium model.

以往对换热器壳程流场和温度场的数值模拟都是建立在多孔介质模型基础上进行的，存在许多问题。

In the planting industry, vigorously develop the characteristics of green cultivation, the city's characteristics and the development of crop cultivation area of 260 hectares, mainly in mushroom Niao, without a shell of white melon, black bean and other crop-based economy.

在种植业上，大力发展特色、绿色种植，全市特色作物种植面积发展到260万亩，主要以菰茑、无壳白瓜、黑小豆等经济作物为主。

It is not difficult to see that just cleaning the end of the campus, students have dropped our drinks cans, paper bread, melon seeds shell; in the campus clean, a classmate we lost the paper, throw the garbage; acoustic sound of loud reading in the book the classroom, some students have the spirit of the doldrums; silent in a quiet study hours, and some students even chirp loudly in the hubbub; in a solemn flag-raising ceremony, some students did glance right and left, whispering.

我们不难看到，刚清扫结束的校园里，就有我们同学扔下的饮料罐，面包纸，瓜子壳；在整洁的校园里，有我们同学丢的纸屑，扔的垃圾；在书声琅琅的课堂上，有的同学却精神萎靡不振；在安静无声的自习课时，有的同学却在叽叽喳喳甚至高声喧哗；在庄严肃穆的升旗仪式上，有的同学却左顾右盼，窃窃私语。

To establish the constitutive equation of material, the metric tensor for stress , strain and their transformation equations between different configurations are derived, and basic theory of finite deformation as well as elasto-plastic deformation criterion are studied. By analyzing the applicability of different element models, four-node quadrilateral degenerated Mindlin isoparametric element is adopted because of its good versatility, and the element stiffness matrix is derived. The static implicit elasto-plastic finite element equation for complex skin stretch-forming is put forward based on Updated Langrange formulation.

本文首先系统地阐述了有限变形的相关基本理论，针对板料成形建立了应力应变度量张量及其相应的转换关系；介绍了材料的屈服准则、塑性变形强化规律、塑性流动规律以及加、卸载准则，并在此基础上建立了有限变形各向异性弹塑性本构方程；对板料成形的单元模型进行了分析，针对飞机蒙皮零件特点，采用通用性强的四节点四边形退化Mindlin等参壳单元进行成形模拟，并导出其单元刚度矩阵的具体形式；基于以上研究，以逐级更新Langrange描述的持续虚功率原理为基础，建立了率形式的复杂蒙皮拉形过程静态隐式弹塑性有限元方程。

Shells are the Mollusca who are with hard covers. They are the most noticeable little animals and also are organisms that evolve extremely successfully.

贝类是指有壳的软体动物，它们是最引人注目的一群小动物，也是一群演化上极为成功的生物。

The shadow of photographer George Steinmetz's plane glides along Kenya's section of Lake Natron, where microorganisms living on the water's salty crust create a palate of pink.

摄影师乔治·斯坦梅茨乘坐的飞机掠过肯尼亚的纳特龙湖上空，飞机的影子投射在湖面由微生物形成的粉红色盐壳上。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.
