删除无效约束技术就是在近似射线步以后，根据一定的准则，将约束分为无效约束和有效约束，删除无效约束，保留有效约束，减小优化模型的规模，提高求解效率。

In the second chapter several new concepts of elasto-plastic fuzzy stiffness and element are proposed. The fuzzy element matrixes corresponding to the elasto-plastic fuzzy element are also established. In order to use the bilinear and trilinear restoring force modles on analysis seismic responses of structures. A fuzzy mathematical method for dealing with the critical points of the restoring force curve is proposed too.

第二章针对结构在地震弹塑性分析中的刚度模糊性，提出了模糊刚度的概念，并进一步对平面和杆系的弹塑性问题提出了弹塑性模糊单元的概念，建立了相应的模糊单元刚度矩阵；为了利用现有的折线恢复力模型，并且更好地反映结构刚度的过渡性，还给出了用模糊数学处理折线恢复力模型刚度折点的方法。

The results indicated that (1) the economy in Zhejiang Province was in the developing stage of unchanged scale wage;(2) the inputoutput elasticity coefficients was the most sensitive to labour element among the factors which had effect of economic growth in Zhejiang Province.The results showed that the coefficient was 0.538 5 in labour element while the coefficients were 0.247 3 in land element and 0.321 6 in fixed asset elements respectively;（3）the contribution of the input of fixed assets was 6823% and still the major impetus to economic growth during this time;(4)the land use was not intensive basically in Zhejiang Province,the input of land elements was replaced by that of other elements during the study.So,labour intensive industry should be one of the industries in the future.

研究结果表明：(1)就规模效应而言，浙江省的经济增长处于规模报酬不变的发展阶段；(2)浙江省经济增长对劳动力要素的投入最为敏感，其中土地要素、劳动力要素和资本要素增加1个单位的投入量对经济增长的推动为 0.247 3、0.538 5 和 0.321 6；（3）固定资产投入在研究期间是浙江省经济增长的主要推动力，其贡献率达到6823%，而劳动力要素与土地要素则分别为2346%和625%；(4)浙江省土地利用不够集约，在研究期间土地要素对经济增长的影响能被资本要素与劳动力要素有效替代，而劳动力要素则难以被资本投入与土地投入有效替代，劳动集约型产业应该成为浙江省未来发展方向之一。
