Brought forward and reasoned the forming mechanism of Maowusu sandy land. Based on the analysis of the development of Holocene rivers and related loess and windsandy geomorphology, the paper put forward the forming mechanism of Maowusu sandy land as follows: while the climate became dry, the exterior channels extended backwardly and cut through the remained lake system of ancient Hetao lake. This resulted in the rapid discharge of underground water. The vegetation living on this water resource was destroyed completely. Then the sand began to form.

对毛乌素沙地的形成机制进行了新的探索基于对过渡地带全新世河流及其相关的黄土和风沙地貌发育、土地利用变化等分析，提出毛乌素沙地的形成机制：在气候变干的同时，外流河谷溯源延伸，切穿了长城以北河套古湖残遗湖系，使地表地下水迅速外泄，原靠湖系水资源维系的生长在河套古湖湖滨沙堤形成的沙地上的非地带植被的生存条件被彻底摧毁，而起沙。

An angular unconformable contact was for the first time found between the Middle Jurassic Bathonian Stage and its underlying pre-Ordovician metamorphosed basement in the Chawola district, in Nyainrong County.

The absorrption of benzoid compound by activated carbon fiber was studied. In theexperiment, the influence of the rate of filtration to the purification effeciency was researched. On the basis of summarizing the principle, advantage and recent research on watertreatment by the activated carbon fiber, adsorption performance of three activated carbons(fibrous, granulose, and powdery) were studied.

选用粘胶基活性碳纤维吸附废气中苯系物，考察了吸附过程中滤速对净化效率的影响，结果表明：滤速为0.20m／s以下时，活性碳纤维对废气中苯系物的净化效率达到90％以上；滤速为0.22m／s时，其净化效率有所下降，净化效率由大到小依次为邻二甲苯、甲苯、苯。

The motion of ships berthed in front of wharfs affect structure and wharf stability, so it is important to study the hydrodynamic response of berthing ships.

码头前系泊的船舶在波浪等外在环境因素作用下产生摇荡运动，船舶运动中对码头设施的碰撞将影响结构强度和码头的稳定性，因此对码头前系泊船舶运动响应的研究是很必要的。

It was found that the phase separation behavior of PPESK, ie., PPESK/NMP/H_2O and PPESK/NMP/NSA, all agree with the LCP correlation. The binodal lines of the three systems were calculated according LCP correlation. Therefore, the maximum content of NSA in the casting solution can be calculated according to the binodal lines of the system, which is a scientific solution for the establishment for the composition of casting solution.

实验结果表明LCP关系可以用于描述PPESK／NMP／H_2O和PPESK／NMP／NSA三元体系在相分离时的浊点组成，并根据LCP关系外推计算三元体系的双节线，由此可得铸膜液体系中非溶剂添加剂的上限含量，为PPESK铸膜液体系组成的构建提供了可靠的科学依据。

Compared with different type male-sterile line found at binucleate microspore stage non-1B/ 1R type male sterile lines and YS type male sterile lines both increase l7kD polypeptide compared with maintainers.
