Ac? 231 Pa? 235 U of actinium series in sediment core collected from eastern Pacific were measured by HPGe γ spectrometry.

用HPGeγ能谱法测定了一个东太平洋沉积物岩心的锕放射系核素2 2 7Ac、2 31Pa、2 35 U 。

The underground root systems and the plenty of adventive roots growing on basis trucks can greatly reduce soil erosion by reservoir water. The 1 m×1.5 m allocation density of the Salix viminalis showed the best protection, and sediment yield was 8.64 kg/m^2, which decreased 74.38% compared to CK.

柳树根系及主干基部长出的大量不定根，可减缓水库水流对滩地土层的冲蚀，以青刚柳1m×1.5m密度配置的防护效果最好，冲蚀量仅8.64kg/平方公尺，比对照减少74.38%。

Then it defines that thebackground value of soil erosion of the middle Yellow River is 650-1000 millon tons/year according to thetwo-way calculation results of aggradation volume of the river alluvial fan and sediment deposition volumeof the ancient river mouth, after comprehensive consideration and under the conditions of less...

然后根据由黄河冲积扇的堆积量和古黄河口泥沙淤积量两种途径的推估结果，经综合考虑后认为，在历史上人类活动较小情况下，黄河中游土壤侵蚀的自然背景值为每年6.5～10亿t。

This is obviously influenced by the base level up and down changings, pore space variation and sediment alimentation. Through analysing the relationship between the course of base level up and down cycles of high resolution sequence strata and the reservoir physical behavior, six heterogeneity models of diff...

通过高分辨率层序地层的短期基准面升、降旋回过程与储集物性关系的分析，建立了6种不同沉积微相的非均质性模式，探讨了向上变深、向上变浅的非对称型和向上变深后复变浅的对称型短期基准面旋回层序对储层非均质性特征的控制作用

The stability of aloin decreased with the increase of temperature and heating time. However, the absorbency of aloin did not change with time under room temperature (20℃). The aloin was sensitive to light, and the aloe juice showed a yellowish green sediment in 2 hours after exposed to sunlight. The stability of aloin declined when the pH value arose. The aloe juice was more stable under lower concentration of sodium chloride and sucrose.

结果表明：加热的温度越高，时间越长，芦荟苷的热稳定性越差，而在室温下(20℃)芦荟苷的吸光度基本不随时间改变；芦荟苷具有光敏性，在太阳光照射下，2小时后便出现黄绿色沉淀物；芦荟溶液随着pH的升高，其稳定性下降；低浓度的氯化钠和蔗糖对芦荟汁液稳定性的维持比高浓度的效果明显。

With the development of coastal and offshore engineering , there is a serious sediment deposition in the neighborhood of fore and aft of alongshore pile wharf. The problems are paid more and more attention .
