Based on the WM-model, the various stages of SPIF process was studied and the forming characters have been realized. Based on the SM-model of the truncated cone, the blank thickness element was sub-meshed into three levels. And through the forming simulation of the process, access to the plate stress and strain of the different regions in forming, and proposed the establishment of a sub-regional mechanism to explain the incremental forming, that is, in different regions, sheet deformation is different. In the main region which reflects the major character of SPIF, the deformation pattern is the composition of bending and extrusion.

基于完整有限元分析模型对渐进成形过程的各阶段进行分析，从而全面认识渐进成形的特点；基于方锥台件局部有限元分析模型，并将板材厚度方向的单元细分为三层，通过成形过程仿真，获取成形中，板材不同区域的应力、应变情况，提出并建立分区域的渐进成形机理解释，即，在不同区域，板材的变形方式是不同的，其中，对体现渐进成形主要特点的方锥台件和圆锥台件的侧壁充分变形区域，其变形方式是拉伸-弯曲复合变形。

This thesis analyzes the types and art trait of solar-assisted heat pump water heater, the development trend of direct expansion solar-assisted heat pump water heater, makes a summary of these research results from six aspects. On the basis of these works and from the point of view of receiving optimum solar radiation , the thesis develops a novel design model of direct expansion solar-assisted heat pump water heater with a truncated cone collector/evaporator, theoretically analyzes the heat that the system can absorb, compares its ability with other two types of cylinder and flat plate ones, and calculates COP and EER with computer aids. The results show that a truncated cone direct expansion solar-assisted heat pump water heater can absorb not only more solar energy but heat energy in air. It takes on favorable thermal performance. Under the average day in February which is of the worst weather throughout the year in Kunming, the COP is about 4. 2, EER is about 2.9 . The heat absorbed by the system are more than those of the other systems. The system is very great in terms of saving

本文分析研究了太阳能热泵热水系统的分类及技术特点，直膨式太阳能热泵技术国内外发展趋势，从六个方面对直膨式太阳能热泵热水系统的研究进行了归纳总结；在此基础之上，从太阳辐射的最佳接收考虑，提出了集热器／蒸发器为圆台侧面的圆台型直膨式太阳能热泵热水器的设计模型，理论上分析了这种热水系统所接收的太阳辐射和得热量，并与圆柱型、平板型的直膨式太阳能热泵热水系统进行对比分析，通过计算机辅助模拟计算出：系统不但可以有效地吸收太阳能，还能有效地吸收空气中的热量，具有良好的热性能；在昆明，以2月为代表的冬季，其太阳辐照较低，系统的制热系数COP值也能达到4.2，效能比EER值为2.9；系统的得热量高出圆柱型、平板型的直膨式太阳能热泵热水系统，节能效果明显。

After amputation, the expression of desmin appears first in the distal end epidermis and the peritoneum 4 d PA. The expression in the peritoneum lasts to the 14 d PA when expression of desmin appears in the musculature, while that in the distal end epidermis only lasts to the 8 d PA when the connective tissue below begins to express desmin. Moreover, from the 4 d PA, musculature and epidermis of the tube foot begin to express desmin and the expressions last to the 20 d PA. From 8-14 d PA, musculature of the ambulacral plate expresses myogenin and the peritoneum also expresses myogenin from 14-20 d PA. All these results indicate that precursor cells for muscle regeneration in adult starfish A.rollestoni are mainly from the distal end epidermis and the parietal peritoneum.

创伤后第4 d，顶端表皮层及体腔上皮中首先出现了desmin表达，体腔上皮中desmin的表达一直持续到第14 d，此时其上方的肌肉组织中也出现了desmin表达；而顶端表皮层中desmin的表达仅持续到第8 d，同时其下方的结缔组织也开始表达desmin；此外，从第4 d起，管足肌肉及管足表皮层开始表达myogenin，且该表达一直持续到创伤后的第20 d；而第8 d起，步带板肌肉也出现了myogenin的表达，此表达一直持续到第14 d；从第14 d起，体腔上皮也出现myogenin表达，且一直持续到第20 d。
