A new special economical experimental unit which applies to the R717 recurrence system of the screw compressor with the economizer has been designed and set up. The experiential results of the single stage recurrence and recurrence with the economizer, such as refrigerating capacity, shaft power, volumetric efficiency etc, under different conditions are got from the experiments. The author analyze and the calculate results of theory in this paper.

There exists a positive correlation in the analysis of the relationship between the students" proficiency test of self-explanation and academic performances in the correlation reaearch of the students" proficiency test of self-explanation and academic performances: there is a close relationship between academic performances of students and the mastery level of chemical concept study. As for the students with higher level of self-explanation,their quality of learning is higher and their academic performances are relatively better, proving that there is a close positive correlation between the academic performance of the test subjects and their self-explanation ability.

在对自我解释水平与学科成绩方面的相关性的研究中通过对被试学生的自我解释水平测试与学科成绩之间的分析发现了两者之间存在着正相关；学生的化学学科成绩与化学概念学习掌握水平之间存在着密切的关系，自我解释水平较高的学生化学概念学习质量较高，学科成绩也比较好，化学学科成绩与学生自我解释水平的存在着密切的正相关。

Installation technology and application of the long-distance grp sand pipe;2. drainage pipe and field test of GRP sand pipe construction technology, we draw the conclusion that GRP pipe is applicable for drainage pipe of port engineering.

通过对玻璃钢夹砂管与钢筋混凝土排水管的综合性能比较及对玻璃钢夹砂管施工工艺的现场测试，得出&玻璃钢夹砂管完全适用于港口工程的排水管道&的结论。

With CAE analysis, multi-body dynamic model of the loader is established with multi-body dynamics software of finite element NAS-TRAN and MSC Adams/View during design period. Various curve functions are added in dynamic analysis model to simulate the terrain excitation on tires and conduct dynamic calculation and analysis. Stress change vs. time of each part is easily obtained when a loader travels on rough terrain. Compared with test results of the physical prototype, the calculation results are relatively consistent.

利用CAE分析手段，在产品的设计阶段，利用有限元NASTRAN和MSC Adams/View多体动力学软件建立装载机的多体动力学模型，通过在动力学分析模型上加入各种曲线函数来模拟路面对轮胎的激励，进行动力计算分析，很容易获得装载机在通过不平路面时各部件应力随时间的变化值，并将其计算结果与物理样机的测试结果进行对比，两者的结果比较一致。
