Furthermore, this paper presents a courseware standardization model based on XML. Faced with so many nonstandard courseware, this model which aims at attaining the two criteria, i.e. IMS and CELTS, makes full use of XML technology to realize courseware resource standardization from two aspects, i.e. courseware resource meta-data and content packaging.

在此基础上本文提出了一种基于XML的课件资源规范化模型，该模型以IMSCELTS规范为目标，针对目前大量存在的非标准课件，充分利用XML技术，分别从课件资源元数据标识和课件内容包装两个方面来实现课件资源的规范化。

Phosphorylated chitosan (phosphorylate-modified chitosan,P-CTS) was synthesized by the reaction of monosodium orthophosphate with urea in the presence of HAc.

壳聚糖(chitosan，CTS)是由β(1~4)键合的D-葡糖胺残基和数目不同排列无规的N-乙酰基葡糖胺残基组成的线性多糖，是生物界中大量存在的唯一的一种碱性多糖。

Base on the problem of large quantity fatigue loads on corroded R.C. structure and small quantity study of its mechanical property, bending resistance fatigue test of corroded R.C. beams is discussed in this paper. The influence of stress ratio and re-bar weight loss ratio on bending resistance fatigue performance of corroded R.C. beams are researched, and the relation between strains of corroded re-bars and fatigue life of beams are obtained. The main research contents and conclusions are as following: 1. Under the fatigue loads, the overstrain of concrete approximately coincidences three stages strain development and accumulation rule, and the mechanical property of concrete is deteriorated. The fatigue damage of concrete is accumulated. The overstrain of re-bars increases and the increase rate decreases.

鉴于实际工程中大量存在腐蚀钢筋混凝土结构承受反复荷载作用，但其力学性能研究不多的问题，本论文进行了锈蚀钢筋混凝土梁抗弯疲劳试验，研究了应力比和钢筋锈蚀率对锈蚀钢筋混凝土梁抗弯疲劳性能的影响，得出了锈蚀钢筋的应变与构件疲劳寿命之间的关系曲线，主要研究内容及结论如下：(1)在循环荷载下，混凝土残余变形基本符合三阶段变形规律，力学性能劣化，疲劳损伤积累。
