With regard to the current society, much hubbub in the European Union ban on the use of four kinds of children's toys, plasticizers, Jiangnan University, and Dr. LG Chemical in two epoxy esters, briefed the meeting on high molecular weight plasticizers, citrate butyl ester, such as trimellitic several environment-friendly non-toxic plasticizer that can be replaced ethylhexyl phthalate, ethylhexyl adipate, whether it is synthetic process, the source of raw materials are not a problem, but there are differences in price, but into the large-scale production, the price will be decreased substantially.

关于目前社会上闹得沸沸扬扬的欧盟禁止在儿童玩具中使用四种增塑剂，江南大学和LG化学的两位博士在会上介绍了环氧酯类高相对分子质量增塑剂、柠檬酸三丁酯、偏苯三酸酯等几种无毒环保型增塑剂，认为完全可以取代邻苯二甲酸乙基己酯、己二酸乙基己酯，无论是合成工艺、原料来源都不成问题，只是在价格上还有些差异，但进人大规模生产后，价格会有较大幅度下降。

In chapter 2, we focus on derivation of the tortuosity models for flow of Newtonian incompressible fluid in two- and three-dimensional porous media with spherical, cubic and plate-like particles by applying the geometrical method. We first present the ideal geometrical models of porous media to show the ideal and representative streamlines based on the assumption that some particles in porous media are unrestrictedly overlapped and hence of different configurations, then the average tortuosity is derived by geometrically and weightedly averaging these representative flow paths.

第二部分采用几何分析法研究了二维和三维情况下的球形颗粒、立方体颗粒和板状颗粒多孔介质中流体流线的迂曲度，首先给出多孔介质的理想几何模型，通过分别考虑固体颗粒重叠时、不重叠时以及粒子的不同排列等情形时的流体流线，然后对这些理想代表性流线的迂曲度取几何平均和加权平均，最后推导出流体流过多孔介质的迂曲度解析表达式。

Urachal anomalies in nine adults were diagnosed by ultrasongraphy; in three, by clinical picture; but in two adults, diagnoses were made only after exploratory laparotomy.

而在诊断上，有9例主要是利用腹部超波诊断，3例是利用临床症状直接诊断，但有2例是在剖腹探查后才确定诊断。

I drew a bold black and white butterfly pattern and took it to Mrs. Vidian. She knitted it into a sweater. The result, I thought, was wonderful. Then came the test. I wore the sweater to a luncheon which people in the fashion business would attend. To my great pleasure, the sweater was noticed. In fact, the representative of a large New York store wanted 40 sweaters to be ready in two weeks.

我绘制了一个醒目的，黑、白两色蝴蝶，并让威蒂安夫人把它编织在毛衣上，结果非常好看，然后到了测试环节，我穿着这件毛衣到时装生意人会去的地方吃午饭，果然，这件毛衣引起了别人的兴趣，这令我非常高兴。

A where enhanced some what through putting in two kinds of zoobenthos as Bellamya purificata and Misgurnus anguillicaudatus in plant cultivated channels of water purification system of hydroponic biofilter method compared with not putting in zoobenthos channel.

在水耕植物过滤法净水系统中的植物栽培廊道中，通过投放2种底栖动物螺蛳和泥鳅延长食物链后，TN、TP、TOC、Chl.a的去除效果均比未投放底栖动物的廊道有所提高。

For the first time, we observe the polarization effect in two-core fiber interferometers, for which we give our analyses and explanations in the thesis. This effect can be used to improve the S/N ratio and the stability of the system. Meanwhile, we did experiments to measure strain within a deformed cantilever, and the results are in agreement with our theory.

本文分析探讨了双芯光纤应变干涉测量的基本原理，对实验系统及现象进行了较为详细的分析，首次发现并验证了双芯光纤干涉中存在的偏振效应，提出了提高系统信噪比和稳定性的新方法；同时进行了一些实验研究，取得了与理论基本一致的结果。

The thickness of the alloying layer is 80μm in the decarbonizing and then surface alloying, but only 15μm in the surface alloying directly. The content of cobalt which doesn't form carbide doesn't have a great difference in two processes, but that of tungsten and molybdenum make a great difference.

在两种渗金属条件下，表面合金层的非碳化物形成元素Co含量差别不是很大，而强碳化物形成元素W和Mo的含量却有着显著差异，直接渗金属的，表层W和Mo含量几乎为零，而脱碳后渗金属的，表层W和Mo总量最大达到6%左右。
