迁移数

It proves the singular transport operator generates a strongly continuous C_0 semigroup V(t0)and the weak compactness properties of the second-order remained term of the Dyson-Phillips expansion for the C_0 semigroup V(t0)in L1 space,and to obtain the spectrum of the singular transport operator only consist of,at most,finitely many isolate eigenvalues which have a finite algebraic multiplicity in trip Γ.

证明了这类方程相应的奇异迁移算子产生C0半群和该半群的Dyson-Phillips展开式的二阶余项是弱紧的，从而得到了该迁移算子的谱在区域Γ中仅由至多有限个具有限代数重数的离散本征值组成等结果。上饶师院数学与计算机系江西上饶334001；南昌大学数学系江西南昌330047袁邓彬

Epidermal cells near the wound dedifferentiate and proliferate forming blastema and/or migrate to the wound plane forming a pre-epidermis consisting of several layers of stem cells covering the wound plane, which then re-differentiates further forming fully developed epidermis. Cells in the parietal peritoneum are also induced by injury to dedifferentiate into stem cells which then proliferate and migrate along the parietal peritoneum to the wound place forming a pre-peritoneum which re-differentiates into fully developed parietal peritoneum.

伤口愈合包括伤口闭合、顶端表皮层及体腔上皮的新生：创伤后的前4 d，残腕顶端的肌肉组织向伤口处迁移并重排使伤口闭合；创伤附近的表皮层细胞发生脱分化并增殖后迁移到创伤面形成由数层干细胞组成的前表皮层，之后进一步分化形成表皮层；而体腔上皮细胞在创伤诱导下也脱分化并增殖，然后沿体腔上皮迁移到创伤处形成"前体腔上皮"，经再分化形成新的体腔上皮。

The basic procedures of the experiments were:(1)rule training:thisis pretraining in order to make subjects attend gradually to the numberdimension of stimuli,and master the rule of number matching.(2)formaltraining:a variety of cards loading number"3"or"5"served as samplesand comparisons.(3)transfer test,test trials were interposed among usualtraining trials of each session,the number is from 1 to 9,and three typestransfer test were proceeded.

两个实验的基本程序为：（1）规则训练阶段：用几个步骤使被试逐渐注意刺激的数维度，并掌握数目匹配原则；（2）正式训练阶段：数目3、5的多种变式作为样本和比较刺激，通过被试在各种样本和比较刺激对上的反应分析它们所利用的线索；（3）迁移测试阶段：将迁移测验随机插入每天的正式训练中，数目扩展为1至9，以验证被试数能力的抽象程度。

The phosphate-type polymer electrolyte is stable up to 10V and lithium ion transference number increases a little appreciably with the side chain length increases.

体系电化学窗口达到10V，锂离子迁移数随着侧链链长的增加略有增加。

A novel anion exchange membrane with chitosan and quaternized chitosan has been prepared and the primary structure characterization has been performed by FTIR. The influence of various chitosan/quaternized chitosan compositions and the amounts of glutaraldehyde on properties of ion exchange membranes was discussed. The ion transference number and the selective permeability have been estimate by testing membrane potential method.

The ionic conduction of La2Mo2O9 was predominant with the electronic transference number less than 0.05 above an oxygen partial pressure of about p O2=10-7Pa at 700 ℃, and below this pressure the electronic conduction became obvious.

在700oC、氧分压高于10－7Pa条件下，离子传导占主导地位，电子迁移数低于0.05，而低于这一氧分压时，电子传导开始变得明显。

They are thought to rear primarily in Cambodia's Tonle Sap Lake and migrate hundreds of miles north to spawning grounds in Thailand.

人们认为，这些主要是在后方柬埔寨洞里萨湖和迁移数百英里北到产卵场在泰国。

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

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
