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.

A correlation of the experimentaldynamic response of the vessels with the theoretical finite element calculations ispresented and discussed.1 The response of the end caps is dominated by transverseand torsional deformation of the plates.The membrane strain is negligible compareto the lateral strain.2 In the lengthwise direction of the inner cylinder,themembrane strain has the same magnitude as that of the bending strain. But for theouter cylinder,the former is much smaller than the later at the same direction.3 Forboth the inner shell and the outer shell,hoop strains are primarily due to themembrane deformation.The amplitude of the circumferential flexural strain isconsiderably small.4 Peak strains in the vicinity of the connection portion of theend caps and the shells are very high.This is important to assess the safety of thecontainer in case of repeated use or tests.5 The applying load to the end cap isdifferent from that to the inner shell plate, but peak stains and nodal displacementsof these two structural parts are nearly the same.It can be inferred that the dynamicresponse of the end cap is greatly affected by the structural vibration excited by theimpulsive loading.

结果表明:1在本文所考虑的载荷水平下,平板变形以板的横向弯曲和扭曲为主,中面应变幅值比较小。2对于内容器,其纵向变形中弯曲应变和中面应变大小接近;而对于外容器,其纵向变形以弯曲为主,中面变形比较小。3内、外壳体的环向变形主要是中面应变,弯曲应变分量很小。4平板和壳体连接处应变很大,这对于多次使用或实验时评价结构安全有指导意义。5尽管内筒底板和大封头上的作用载荷有一定差别,但应变峰值和节点位移峰值基本相近,这说明脉冲载荷激发起来的结构振动对封头的动态响应有很大影响。
