Analysis on Micro-structure of TiN Thin Film and Polyimide with AFM

The study in molecular morphology is given with a highresolution Atomic Force Microscope AFM.IPC-208B.By taking TiN thim film prepared by magnerton sputtering method and polymide(PI) fibre for examples,the preferenthal growing plme of TiN thin film,the atomic arranges of TiN thin film on the preferential growing plme and the surficial micro-structure can be ascertained form the three-dimensional images obtamed by AFM.IPC-208B.These experiments not only identify small structures of the materials,but also affirm that AFM.IPC-208B holds the precision of atomic level and potential application in micro-structure field,at the same time it establishs the groundwork for the application in micro-process kingdom.     

A Comparative Study of Confined Concrete Models under Cyclic Loading

In this paper,four models are selected as the representatives and applied to nonlinear dynamic analysis program for space frames which is based on the beam-column elements using the finite element flexibility method and the fiber model.Park's test on combined axial and bending columns under cyclic loading are taken as the calibrations,comparisons to material and structural member level are drawn and the analytical results of various models are discussed.     

Optimum Planting System for Energy Saving and Healthy Demanded

It is proved that planting is effective to improve environment both indoor and outdoor resulted from the functions of plants to clean air and save energy. So the contradiction between saving energy and comfort,healthy demanded by people can be solved by planting. The planting have being emphasized and expanded during recent years,but in the planting plan,just the function of beautifying the environment is concerned and the function of ecological and saving energy are neglected. The analysis on the ooptimum system of planting is to make the planting system as an organic composition in the effectiveness structure and space layout of the city. Based on the study on equivalent relation of different effects on environment, the optimum system of planting structure will be determined in order to achieve the integrated effects of planting on environment.     

Summarization of Current Research on Application of Durability of Structures

This paper summarized the recent research results about the durability of structures, introduced their current application in durability design, appraisal, estimation of rest life and strategy of maintenance and strengthening as well as in other fields.     

Nanometer Scale Surface Roughness Measurement Based on AFM

The datum line and mainly three profile height parameters of surface roughness are briefly introduced and the operation principle and system structure of AFM. IPC - 208B with high-resolution, which was successfully developed by Chongqing University, are described in detail, and the emphasis is laid on its application on the nanometer scale surface roughness. Taking stainless steel for example, its micro-structure was observed, and the surface data were analyzed and transacted by special evaluator and the values of three profile height parameters were obtained. Finally the experimental results are briefly analyzed.

宽垄沟灌覆膜条件下土壤水分运移初探

宽垄沟灌作为一种大田作物栽培灌水方式已逐步受到关注.为研究灌水前后水分在垄沟间的运移及再分布,本试验在大棚内模拟宽垄沟灌垄上覆膜栽培条件以及灌水方案,采用中子仪进行水分观测.试验数据显示,在本试验条件下,垄背剖面的两个观测点表层,灌水前其含水量仅为田间持水量的65%和66%,灌水后垄沟水分的侧向入渗,144 h(6 d)分别达到田间持水量的73%和80%,408 h(17 d)达到田间持水量的78%和79%.试验结果表明,在宽垄沟灌覆膜条件下,水平向及垄背垂直向含水量梯度的存在导致水分侧向及向垄背的补给明显,且在覆膜条件下,垄背蒸散发损失少,起到减少土壤水分无效损耗、高效利用之效果.
