Selaginella extract was given for 26 weeks,ALP,TRAP,BGP,TNF-αlevel of drug group A were significantly lower than the model(P.01);E_2,CT level in drug groups increased significantly(P.01),group A and group D were the most obviously.Dosage in group D was only 1/4 of the dosage level in group A.

Chromosome pairing behavior in meiosis of the hybrid F1 was carried out. Results showed that in an average , 1.25 rod bivalents were observed in one PMC, meiotic configuration was 2n=14=11.49Ⅰ+1.25Ⅱ(Xta=1.25) and most of PMCs possessed 1～5 bivalens, indicating that the relatively high homeology was detected between the D genome of Ae.tauschii and the V genome of D.villosum. The morphological differences between F1 hybrids and their parents were significant. F1 plants were highly self-sterile, but partially self-fertile after treated by chromosome doubling technique.

Through making diagrams using matlab program ,first we must know submits the shearing force coefficientα_s, the space characteristic Tg, stiffness concern a modulusβ, biggest shearing force coefficientα_.Then we can get shaking tier of base shearing force modulusαand shaking tier of displacement across D, which will define structure basis shearing force F_ and verify if structure displacement D satisfy standard structure request displacement . Therefore, the designer can estimate the earthquake reaction of the composite base isolation structure directly.

通过matlab编程，制作图表，在给定屈服剪力系数α_s，场地特征周期T_g ，刚度关系系数β，最大剪力系数α_情况下，可得到隔震层基底剪力系数α和隔震层位移D，从而确定结构基底剪力F_，并验证结构位移D是否满足规范结构要求位移，设计人员可以直接估算出复合隔震结构的地震反应。
