沉积不断

The continual expansion of sand dike outside the shore and sandspit of the Yangtze River and Huaihe River, in addition to siltation of the Yangtze River and Huaihe River, caused Sheyang Lake to change gradually from semi-seal to whole-seal.

岸外砂堤，长江、淮河沙嘴的不断发展，以及长江、淮河所携泥沙的沉积作用，使射阳湖逐步由半封闭转向全封闭。

With the increasing transportation of liquid chemicals in bulk by ships, the risk of the chemicals spill is getting higher and higher. So the reasonable numerical modeling of the spilled chemicals at sea is a key technique for the risk assessment and contingency decision-making. The sinkable chemicals spilled at sea always ended in sediment, so the design of decision-making support system for sinkable chemicals spilled shipboard have academic and applied sense.Based on the analysis for the environmental harm caused by the transportation shipboard of chemicals and research on related ordain in the international common and intestine law , the paper analysis the impelling need of establishing related respond system for contaminative accident.

随着海上液体化学品运输、中转量的不断增加，化学品泄漏风险也日益增加，对海上泄漏化学品行为进行合理、可信的数值模拟，而沉降型化学品由于最终进入沉积物而可能带来更大的潜在危险，故并在此基础上构建GIS支持下的海上溢漏事故应急决策支持系统具有重要的理论意义和实用价值。

In the lower region , the elevation of beach was higher, the plant density and biomass increased and the habitat space was enlarged, so the species and individuals numbers of benthos were both more than the uppers.

从低潮区、中潮区再到高潮区，植株高度及地上部分生物量逐渐增大，初级生产力的不断提高，沉积环境的稳定性加强，底栖动物多样性及物种丰度也相应增大。

By moving electron beam, we guide the deposition of a-C into the center of electron beam, so as to get the desired nanostrucures, such as nanowire, nanosopts, etc.

通过移动电子束，引导无定型碳不断地趋向束斑中心而沉积，从而生长出我们想要的纳米线、点等结构。

Eventually, however,the continued flow washed most of the sediment out of the canyon. This problemwas avoided in 2004, but unfortunately, on that occasion, the volume of sandavailable behind the dam was too low to rebuild the sandbanks.

可是最终，持续不断的水流将多数沉积物冲出了峡谷。2004年时避免了这个问题，但偏巧那时大坝后可用的泥沙太少，不足以重建沙洲。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
