Aging mechanism of wood-plastic composite was: light and heat break down the long molecular chains of wood flour and plastic; the free radicals reacted with the oxygen, which generated carbonyl groups, hydroperoxides and so on; the free radicals also had cross linking reaction, which generated alkoxy; Water destroyed the interface of wood flour and plastic, hydrolyzed ester additives, extracted the small molecule additives and degradation products; Microorganism degraded cellulose, semicellulose, lignin and ester additives; degradation product from different component accelerated the aging, which could be exampled by the fact that HCl from degradation of PVC accelerated the hydrolyzation of cellulose and semicellulose.

木塑复合材料的老化机理为：光和热引发木塑复合材料中木质组分和塑料组分大分子链断裂，产生的自由基与氧气作用，发生链支化反应生成羰基、氢过氧化物等，发生交联反应生成烷氧基等；水分破坏木-塑界面、水解酯类添加剂、抽提小分子添加剂和降解产物；微生物分解纤维素、半纤维素、木素和酯类添加剂；木塑复合材料中各组分的降解产物相互促进老化，PVC降解产生的HCl溶于水，促进了纤维素和半纤维素的水解。

The lime slaking rate is the important factor of the quality of the hydrated production.

消化产物的特性主要有生石灰的转化率、消化产物的粒径和比表面积等。

The hydration process of lime has important influence on lime slaking rate、 particle size and specific surface, so it is significant to research the hydration process.

生石灰的转化率是衡量消化产物品质的重要因素；熟石灰的粒径越小，比表面积越大，其利用率也就越大；生石灰的消化工艺无论是对消化产物的粒径、比表面积和孔隙率还是含水率都有很大的影响，因此有必要进行实验研究。

There are two evolutional trends for sodic basalts: alkaline basalt to sub-alkaline basalt and to the contrary. The fact that alkaline basalt has the higher concentration of incompatible elements and the sub-alkaline lower indicates the increasing degree of the partial melting in the mantle sources. The variety of Sr, Nd isotope compositions in different types of rocks shows their different mantle sources.

钠质玄武岩存在着碱性玄武岩到亚碱性玄武岩和亚碱性玄武岩到碱性玄武岩的变化序列；碱性玄武岩到亚碱性玄武岩不相容元素丰度逐渐降低，表明为部分熔融程度逐渐增高的产物；Sr、Nd同位素组成与岩性之间的相关性表明，各种岩浆是不同地幔源区部分熔融的产物。

It is suggested that mechanisms protecting epidermis of squamata species from UVB damage may involve in (1) Physical defensive mechanism: the death epidermal layer limited UVB transmitting to the viable cells;(2) Biochemical defensive mechanism: up-regulated CAT may protect skin from reactive oxygen species which may induced by UVB. Moreover, the lipid and proteins in the β-, meso- and α-layer may absorb incident UVB and formed damaged products that were limited in the original site;(3) Cellular defensive mechanism: quick initiating of proliferation of the germinal cells and forming of the new epidermis and shedding out the damaged epidermis shortened the damage process and restricted the damage area.

1物理性防御：角质层和中层阻挡绝大部分UVB透过，最大限度地减轻生发层的损伤；(2)生化性防御：通过上调CAT活性以减轻LVB诱导的活性氧对表皮的损伤，同时角质层蛋白质和中层脂类可吸收UVB，且形成的有害产物被局限于原位；(3)细胞性防御：通过迅速启动再生修复过程形成新的表皮，及时蜕去积累了脂类过氧化产物、受损蛋白质和晒斑细胞等的受损表皮，有效防止损伤的持续和蔓延。

In the area of selective catalysis, they will soon publish the first examples of stereochemically thoroughly investigated Enantioselective Organo-Autocatalysis, a process that demonstrates conceptually new catalysis design strategy and also provides structurally well-defined small-molecule models that may help explain the origin and maintenance of homochirality fundamental to the functions of biological systems.
