Secondly, the steady-state productivity model for horizontal well in gas reservoir is established. On the basis of solving the model, this thesis elicits the binomial deliverability equation by which absolute open flow potential and inflow performance relationship can be got and we can forecast the production performance of horizontal well in gas reservoir. In the end, on the basis of the theoretical analysis, this thesis explores homologous nodal analysis program.

其次，在建立水平气井不稳定渗流数学模型并求得其解的基础上，推导出了考虑地层伤害及非达西渗流影响水平气井产能方程，通过该产能方程可求出水平气井的绝对无阻流量，绘制流入动态关系曲线来预测生产动态；最后，在理论分析的基础上建立了水平气井节点分析方法，并开发了相应的节点分析程序。

The effects of many factors in the wet end on drainage and retention of PEO/attapulgite system: During the scope of 2-12, pH has no effect on drainage, and retention ratio lower in acidic conditions and higher in neutral or alkaline conditions. There were some improvement on slurry's drainage and some impairment on retention efficiency for the existence of inorganic salts. Lignosulphonate had no effect on drainage and made retention ratio decrease 5-8%; lignosulphonate and xylan had no effect on drainage and made retention ratio decrease a little. 5 .Attapulgite could be modified by intercalation.

纸机湿部系统的影响因素对PEO／凹凸棒粘土助留体系的助留助滤效果的影响表现为：pH值在2-12范围内，对助滤效果是没有影响的，使助留效果在酸性条件下较差，而在中碱性条件下较好；无机盐的存在使浆料的滤水性能有一定的改善，使助留效果有所削弱；木质素磺酸盐对助滤效果是没有影响的，使留着率下降了5—8％；木质素磺酸盐与聚木糖对助滤效果也是没有影响的，使留着率略有下降。

The North End is thus a recurring assignment for M.I.T. and Harvard planning and architectural students, who now and again pursue, under the guidance of their teachers, the paper exercise of converting it into super-blocks and park promenades, wiping away its nonconforming uses, transforming it to an ideal of order and gentility so simple it could be 9 engraved on the head of a pin.

North End 也因而被反复作为麻省理工学院和哈佛规划建筑专业学生的作业，在老师的指导下，学生们坚持不懈地在纸上把它变得拥有车辆禁行区和公园散步场所，去除其不适宜的用途，把它转变成一个秩序井然和优雅高尚的理想典范，做起来好象简单得微不足道。

Using density functional theory, the adsorption of cyanide on the different sites of Cu(100) surface was studied with end-on and side-on geometries.

采用密度泛函方法，以原子簇Cu14 为模拟表面，对CN自由基分子在垂直和平行Cu( 10 0 )表面不同位置的吸附情况进行了研究，结果表明：通过原子C垂直吸附在表面的顶位是其最佳吸附方式，吸附后CN键振动频率发生蓝移；而其它吸附方式中CN键振动频率均发生红移。
