The four well-known skeleton hydro-power stations of West-East Electricity Transmission Project, named Xiangjiaba, Xiluodu, Baihetan and Wudongde from the lower reaches of Jinshajiang River to upriver reaches, are all distributed in this area. Based on the analysis of the resource exploitation and industry sustainable development status, current problems and future scenarios, the main conclusions go as follows:(1) There are abundant and varied agricultural resources, widely distributed mineral resources with valuable predominant minerals, potential tourism resources, but some main problems such as lower level of exploration and development, serious waste and pollution, restraints of financing and transportation and eco-environmental frangibility still call for immediate solution;(2) Regional economy develops fast but the overall level is low-farming and animal husbandry industries, In which crop-plantation takes the main part, dominates in the sectional structure of economy, and forestry and specialty industries need to be further developed. The existed restraints such as unbalanced structural and regional economic distribution, acute structural deficiency and low economic efficiency need to be cleared out, of the way to a sustainable future.

西电东送骨干工程的向家坝、溪洛渡、白鹤滩、乌东德四大水电站均分布在这一江段通过对该区域资源开发和产业发展的现状、问题和发展前景进行分析，得到如下主要结论：(1)该区域农业资源丰富多样，矿产资源分布广泛且优势矿种地位突出，旅游资源待开发潜力巨大，但是资源开发却面临着勘探开发程度不够、浪费污染严重、资金交通制约和生态环境脆弱等几大问题；(2)区域产业经济发展迅速但总体水平低，部门结构中以种植业为主的农牧业占主导，林牧业和特色产业有待进一步开发，产业发展面临着部类和区域不均衡、结构矛盾突出以及效益低下等问题的困扰。

Zeolite has much especial quality,and it can be used in many fields,therefor human had synthesized more than 100 varieties got-up zeolite.But using of natural zeolite don't have big progress,the main reason is that natural zeolite is low pure and low qualitative.

沸石具有许多特殊性能，在很多领域可以发挥作用，为此人类已合成了100多种人工沸石，而天然沸石的利用却没有大进展，究其原因天然沸石纯度不高性能低是主要因素。

It is included that 4-5 types of active sites exist in the catalytic system and the active site produced polymer with low molecular weight is easy to be activiated while TEA is used as the cocatalyst. While TIBA, the active site produced polymer with high molecular weight and seldom active site produced polymer with low one is prone to be activiated. MAO tends to activiate the active site produced polymer with middle-level molecular weight. In TEA-TIBA catalytic system, TEA and TIBA activiate the corresponding active site and the weight of every active site gradationally varied with the change of the ratio of the two cocatalysts. And the activity of the active site produced polymer with high molecular weight is proportion to the concentration of TIBA.

发现：TEA作为助催化剂时产生低分子量产物的活性中心易于活化，且体系中具有活性的活性中心有4～5种；TIBA易于活化产生高分子量的活性中心，基本上不能活化产生低分子量产物的活性中心；MAO对产生中等分子量产物的活性中心活化能力较强；在TEA-TIBA混合物体系中，TEA和TIBA各自对活性中心的作用表现为明显的互补现象，各活性中心的相对强度随着两种助催化剂之间的比例改变呈现渐次变化，其中产生高分子量产物的活性中心的相对活性(来源：c5AB3fC论文网www.abclunwen.com)与TIBA的浓度有明显的正相关性。

Traditional straightness measurement, such as leveling rule, gradienter, reinforcing wire, even though simple in detecting apparatus and adopted widely, are of certain limitation, low accuracy, low efficiency, and cant guarantee the performance. On the other hand, some other measuring devices cannot be widely used because of value.

传统的直线度检测方法，如平尺法、水平仪、钢丝法等，虽然检测器具简单，实际中常被采用，但各自都存在一定的局限性，测量精度不高，效率低，性能无法保证；而有些仪器却造价过高不利于广泛应用。

Terrain heightened can enhance blocking effect, which lead to strengthen water vapor flux divergence and vertical convection, and cloud water increases but centralizes in the middle-low level. This change intensify accretion of snow by collecting more supercooled cloud water, and rain water converts into graupel by collecting more snow, and dry growth of graupel increase at the same time. Rain water augment because of more graupel melting, and rain water continue to increase by collecting cloud water in the low level.
