The results showed that elevated CO2 increased the R/S ratio and the dry mass of both coarse and fine roots, indicating that the seedlings under elevated CO2 allocated more biomass to their below- ground part. Compared with control, elevated CO2 increased the contents of reducing sugar, sucrose, and total soluble sugar in coarse roots significantly, but had less effect on those in fine roots. Elevated CO2 increased the contents of starch and total non-structural carbohydrate both in coarse roots and in fine roots. Under elevated CO2, the carbon content in coarse and fine roots had an unsignificant increasing trend, while the nitrogen content decreased signifi- cantly, which resulted in an increase of C/N ratio.

结果表明：CO2浓度升高使红桦幼苗粗根和细根的干质量增加，同时根／冠值显著升高，表明CO2浓度升高使红桦幼苗生物量向根系的分配增加；与对照相比，粗根的还原糖、蔗糖和总可溶性糖含量显著增加，而在细根中没有显著变化；粗根、细根的淀粉和总的非结构性碳水化合物含量显著增加；CO2浓度升高下粗根和细根的碳含量有升高的趋势但未达到显著水平，同时氮含量降低，碳／氮值升高；氮的吸收量在粗根和细根中均无显著变化。

The baseline vagal tone of 4 years and 6 years were significantly higher than that of 2 years, but there was no significant difference between that of 4 years and 6 years.

结果发现，基线迷走紧张与迷走抑制有不同的发展模式：4岁组、6岁组儿童的基线迷走紧张显著地高于2岁组，而4岁组与6岁组之间没有显著差异，基线心跳周期随年龄的增长而相应增长；迷走抑制没有年龄差异，6岁组的基线对任务的心跳周期变化显著地大于2岁组的心跳周期变化。

Since we are concerned primarily with the future,it would be better to take no notice of tradition.

文章主要讲了人类的发展离不开变化，传统在变化的世界中有正反两方面的作用，而较好的做法是接受传统所提供的帮助，同时要认识到它的局限性。

The density of flagellates varies in proportion to that of the suspended particles. As a whole, the correlation between flagellates and the suspended particles is obvious, and more characteristics are showed in different types of spectra.

鞭毛虫丰度的变化与悬浮颗粒物的数量分布具有相似的变化趋势，整体上来说，两者数量的相关性显著，而不同的粒径谱类型中，两者的关系有不同的特点。

It is found that compared with the untreated glass fiber reinforced unsaturated polyester, the fluoridized FRP"s property of anti-water and anti infirm-acid has enhanced, while theproperty of anti- strong acid, anti-strong alkali and anti-organic solvent hasn"t changed much.The property of anti-acid and anti-alkali of the glass fiber reinforced epoxy resin fluoridizedby 3-(1H, 1H, 5H-Octafluoropentyloxy)-1, 2-Propenoxide has a corresponding increase, but theproperty of anti-organic solvent hasnt changed much.

研究发现，经G-02、G-04处理后的聚酯玻璃钢的与未处理的聚酯玻璃钢相比，其耐水性增强，耐弱酸性也有所增强，但耐强酸性、耐碱性、耐有机溶剂的腐蚀性变化不大；而经环氧丙基八氟戊醚处理后的环氧玻璃钢其耐酸耐碱性都有相应的增强，但是其耐有机溶剂的腐蚀性无太大变化。

Three ideal developing patterns of groundwater are suggested according to the study in the Liaoning region.1 Shoushan pattern: river and reservoir water to irrigate, and the water percolates into the ground and recharges the water-bearing layer, then pumping the groundwater to supply the industry and city.

在地质历史时期和人类历史时期，地质环境在各种要素的作用下处在不断的变化之中，而且地质环境要素本身也在不断变化之中，不断有新的影响因素产生和加入，而人类的出现及其工程活动则是这些新增加的影响因素中最为重要、最为积极、影响力在急剧膨胀的因素。

Therefore, if the various degrees of suitability reflect qualities, as they do in worthy individuals, so that some are worthy, some worthier, and some most worthy, it is clear that good things are suited to the worthy, better to the more worthy, and the best to the most worthy.

因此，如果适合的变化程度反映了品质，就如在在那些有价值的人身上体现的，那么一些人就是有价值的，一些人比他们还有有价值，而另一些人有最高的价值，很明显，好的东西适合于那些有价值的人，更好的东西适合于那些更有价值的人，最好的东西适合于那些最有价值的人。

The chemical feature change of the restructured soil mainly focus on the research on the changing of soil bulk,water content,structure and chief nutrients.The filling soil by fly ash and waste pile has the possibility that polluted by heavy metal.

重构土壤的理化性状的变化主要集中在土壤容重、含水率、结构和主要养分变化的研究上，在粉煤灰、煤矸石充填的土壤上有重金属污染的可能性。

After the rigidity matrix calculations, the FEM analysis program ANSYS is used to create models, with the truss structure and box cross-sectioned cantilever board beam as models.

在完成结构刚度矩阵计算的前提下，以桁架结构和矩形截面悬臂板为模型，利用有限元程序ANSYS进行建模，分析了不同类型的结构在温度变化作用下的响应，从而得知温度变化对桁架结构的模态参数影响不大，而对矩形截面悬臂板梁的模态参数有一定的影响。

I Such risk shall be deemed to exist if the compass bearing of an approaching vessel does not appreciably change; such risk may sometimes exist even when appreciable bearing change is evident, particularly when approaching a very large vessel or a when approaching a vessel at close range.

在断定是否存在碰撞危险时，考虑的因素中应包括下列各点：（1）如果来船的罗经方位没有明显的变化，则应认为存在这种危险；（2）即使有明显的方位变化，有时也可能存在这种危险，特别是在驶近一艘很大的船舶或拖带船组时，或是在近距离驶近他船时。
