Fourteen sediment samples with different content of Fe〓O〓 were collected from lower reach of the Liao River in China. The photodegradation of γ-hexachlorocyclohexane on the sediment surfaces was investigated to observe the effects of Fe〓O〓 and other photoinducable substances, such as TiO〓 and organic substances, on photodegradation of γ-HCH.

从辽河新民段采集了14种具有不同含量的Fe〓O〓的天然沉积物，为了探讨沉积物中Fe〓O〓和其它具有光诱导和光催化能力的物质如TiO〓和有机质成分对沉积物表面上的林丹的光解的影响，研究了γ-HCH在这些沉积物表面上的光解动力学。

In this case, the solidification of the liquid phase formed at the hipping temperature led to the formation of crystalline intergranular phases at all temperatures: however, the chemical compositions of the intergranular phases formed in the specimens with and without carbon additions were different, since for high carbon contents the resulting intergranular phase was observed to be richer in Yttrium(85% at Y/15% at Si).

在这种情况下，加压温度下液态产物的凝固在所有温度范围下都将生成间粒晶体：但是，是否添加了碳则将会使产物晶体的化学成分发生不同，因为在高碳含量下，产物晶体会更富含钇(85%Y比15%Si)另一方面，我们必须强调的时，如果Al2O3作为第三方物质加入反应混合物粉末中，那么产物晶体的结晶度将被破坏。

Chinese elements are employed instrumentally as empowering ethnic markers to fortify the American cultural values that are at the core of this new culture.

本章通过分析华美作品中的中国文化成分，指出华美作家对中国文化的利用以美国价值尺度为标准，改编甚至篡改其祖先文化传统，目的是为了在多元文化的美国建构出与主流社会既不同又平等的华裔族性，如此创造出来的新文化有如&杂碎&，纯粹是一种美国产品，应该叫美国文化。

One hundred and fifty specimens of Pelteobagrus intermedius from 12 drainage systems were collected to measure 21 morphometric characters using traditional taxonomic methods. Data on the morphometric characters were analyzed using principal component analysis in order to discuss the morphological variation and geographical differentiation of the characters.
