本文系统介绍了斜拉空间桁架竖向地震反应的分析理论与方法、详细分析了斜拉空间桁架结构在静力和竖向地震作用下的受力性能，主要内容包括：利用通用有限元软件ANSYS9.0计算了斜拉空间桁架在静力和竖向地震作用下内力及自由端位移分布规律并得出地震内力系数与节间位置、预应力以及斜拉索高度之间的函数关系；详细分析了斜拉索中施加的预应力以及斜拉索高度的变化对于该种结构内力及自由端位移的影响并提出了斜拉空间桁架的临界预应变概念，进而得到了自由端位移与初始预应变以及斜拉索高度的函数关系，即：△=-(40h+2180)ε+9.8；分析了该种结构的动力性能，并指出：在时域内采用直接积分法计算该种结构的动力响应时，应该考虑采用不引起振幅率减小的Newmark-β法，以保证高阶模态响应的贡献仍然保留在响应中而不致于被忽略。

The results indicate seawater concentration has no effect on absorbency, pH, relative density, dry matter and water contents in Aloe vera leaves. While, seawater stress causes increased MDA and membrane penetration, decreased phytochroms, prolines and NO_3~--N. It is beneficial to plant growth when irrigation was done with 10% seawater, because of higher ratio of K~+/Na~+ and lower ratio of Na~+/Ca~(2+). In addition, the polysaccharide contents in Aloe vera leaves increase twice and triplication under 25% and 50% seawater irrigation respectively, the barbaloin contents increase over triplication in var. 75% seawater and over twice in var. 50% seawater and var. 100% seawater. However, when seawater concentration exceeds 25% the growth of plant was inhibited, biomass decreased, flowering time was deferred, Ca~(2+) content decreased caused by Na~+ accumulation in leaves.

结果表明：在海水胁迫下，库拉索芦荟全叶汁的吸光度、酸度、相对密度、总固形物和水分含量总体上受海水浓度的影响不大；但芦荟叶的丙二醛含量和质膜透性增加，叶绿体色素、脯氨酸和硝态氮含量减少；在10％海水浇灌下，芦荟叶细胞具有较高的K~+／Na~+比和较低的Na~+／Ca~(2+)比，对库拉索芦荟的生长有一定的促进作用；在25％海水和50％海水浇灌下，芦荟多糖含量提高了2-3倍；在75％海水浇灌下芦荟甙含量增加了3倍多，在50％海水和100％海水灌溉下，其含量也增加了2倍多；当海水浇灌浓度超过25％后，库拉索芦荟的生长明显受到抑制，生物量降低，抽苔期推迟，同时，海水浓度的增加也导致芦荟叶中累积大量Na~+，从而使得芦荟叶中Ca~(2+)含量降低，但Mg~(2+)并没有受到海水浓度的影响；用浓度低于75％的海水浇灌库拉索芦荟可以降低剖面深度在0-100cm之间的土壤盐度；其抗氧化保护酶中超氧化歧化酶的酶活力相对保持稳定，过氧化物酶的酶活力在10％海水浇灌下明显提高，随后则下降，而过氧化氢酶的酶活力则随海水浓度的升高而下降。

The moderate traction group demonstrated myelinolysis change in the spinal cord, and neurofibras lined up chaos, auxiliary fibers disaggregated, neuron dropsy, tigroid body disappeared with karyopycnosis and anachromasis in neurons; nerve root showed myelinolysis. The severe traction group displayed a great demyelination region; anterior motor neurons with karyopycnosis and anachromasis; myelinated nerve fiber of nerve root shrinked, decreased in number, with severe demyelination changes.
