不变化

The varying tendencies of partition coefficients of some compounds in aqueous or nonaqueous solvent systems by calculating the phase equilibria with universal quasichemical functional group activity coefficient model are predicted. These compounds included saturated and unsaturated fatty acids ethyl esters,N2,4dinitrophenylamino alcohols, pnitrophenyl glucosides and so on, with simple structures and much differences in polarity.

以饱和及不饱和脂肪酸乙酯、2，4二硝基苯胺基脂肪醇和对硝基苯基葡萄糖甙等结构较为简单、极性差别较大的溶质系列为研究对象，应用修正的通用基团活度系数模型，通过相平衡计算，预测了它们在含水或不含水的溶剂体系中分配系数的变化趋势，并与前人的工作进行了对比。

When the chirped pulse with area smaller than propagates in the medium, splitting doesn't occur and the chirped pulse evolves gradually to an approximate normal Gaussian pulse (C=0), and this characteristic doesn't vary when the chirp coefficient; however, variation of the chirp coefficient will change amplitude and group velocity of the pulse.

面积小于的啁啾脉冲，在介质中传播时不发生分裂，且啁啾脉冲逐渐演化为一个近似的无啁啾(C=0)脉冲，这一特点不随啁啾系数的改变而改变；但啁啾系数的变化将改变脉冲的振幅和群速度。

In order to remedy this shortage, it was put forward that the frame of terrigenous elastic rocks should be expressed as the collaring rectangle instead of rectangle.

对于陆源碎屑岩来说，这样既不能表示出其粒度变化情况，又不能反映出它形成时的沉积动力学特征。

We have aready seen the impact of fast changes on big exhibitions like Comdex,for a few years in the 1990s,it was one of the largest exhibition in the world.

我们已经看到快速的变化对像Comdex这样的大型展览会的影响，在20世纪90年代的许多年间，它是世界上规模最大的展会之一，但如今它已经被拖延2年了，我们有可能再也不会看到它复办，肯定的是，我们再也不会看到他以往的辉煌了。

The instability originated in the upper R_B-like convection zone develops to larger region with the increase of Grashof number, and the number of non-axi-symmetric circulations decreases. When Grashof number exceeds another critical value, cooling air may invade the cavity and flow toward the shroud, the circulations decrease to one pair occupying the whole cavity in radial, thus these two zones are merged into one. The core structures in the cavity rotate against the disks, while the structures keep no change at the case of periodic oscillatory flow. With the Grashof number rises, the flow undergoes stable, periodic, periodic with cool air invading, quasi-periodic and ultimately to chaos.

离心浮升力是造成非等温轴向通流旋转盘腔内流动不稳定的主要因素，而哥氏力的存在加剧了流动不稳定性，导致流场失稳提前发生，而且在哥氏力的作用下流线发生偏转，盘腔内r-θ面出现了旋向相反的对涡，流动结构更加复杂化；随离心浮升力的继续增加，r-θ面的对涡减少，当其超过某一临界值后部分冷流体侵入盘腔，对涡减少至一对，而且沿径向充满整个盘腔；此后随离心浮升力的增加对涡的数量不再变化；r-θ面的对涡相对于盘面周向移动，但是形状基本保持不变。

Electrochromic ion pump caused by changes in the characteristics of membrane potential can cite the following: there is no equilibrium potential; not accompanied by increased membrane resistance; hairy Convolvulus case may disappear, such as glycosides.

电致离子泵引起的膜电位变化的特征可以举出这样几点：不存在平衡电位；不伴有膜电阻的增大；遇多毛旋花苷可消失等。

Wang Qiyao failed to understand that it is precisely this myriad of unchanging little worlds that serves as a counterfoil to the tumultuous changes taking place in the outside world.

这世界就好像藏在时间的芯子里似的，竟没一点变化……王琦瑶不知道，那大世界如许多的惊变，都是被这小世界的不变衬托起的。

The quality changes of Large Yellow Croaker during partial freezing by chilled salt water were studied in this paper.

本文研究了大黄鱼在不同处理(-3℃涂膜盐水微冻、-3℃不涂膜盐水微冻、-6℃涂膜盐水微冻、-6℃不涂膜盐水微冻)条件下其品质的变化。

Second, legal coordination of reasonable structure of social distribution mainly include the relation among state, enterprise and residents, the relation of distribution between center and territory and relation of crosscut distribution.

在经历了20余年的改革发展，社会经济生活已发生根本性变化的今日中国，国民经济的快速增长和社会财富总量的迅速增加，并没有实现全体国民社会福祉的普遍提高，人们实际面对的却是经济总量增长下的城乡居民收入差距的进一步扩大、社会弱势群体的基本生存需要面临严重困境、地区间社会经济发展的严重不平衡等一系列的社会分配的不公平问题。

The longer the soft segments the better the mobility of the softsegments, and the better the crystallizability of the soft segments.

当软链段分子量超过6000后，软链段结晶的完善程度虽然比均聚物差，但结晶能力对硬链段含量的变化已不敏感，其结晶所需过冷度、熔点和熔融热焓在所考察的硬链段含量范围内基本保持不变。
