These results, together with the structural elucidation of the purified polysaccharides described above, indicate that the α-glucans in G. lucidum don't have any remarkable immunomdulating activities, but the effects of β-glucans on immune system depend on their glycosyl residue linkages and sugar chain conformation. Further, it is concluded that the 1, 3-linked backbone, relative lower side chain size and substitution, and a high-organized helical structure are the beneficial structural features for the immunostimulatory activity of β-D-glucans. However, the 1, 6-linked backbone may induce the immunosuppressive effect of β-D-glucans.

结合各纯化多糖的结构与构象分析的结果，可以得出以下结论：赤灵芝中的α-型葡取糖不具有显著的免疫调节作用，而β-型葡聚糖的免疫作用则与其糖链结构和糖链构象有密切关系，1，3-连接的主链，较低的分支取代率和较短的支链长度及高度有序的螺旋结构是β-型葡聚糖发挥免疫增强功能的有利结构因素，相反，1，6-连接的主链却可能引起多糖的免疫抑制作用。

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。
