These were raised underinducing condition to test if any morphology and structure changes. Twenty two Arabidopsismutants had various changes in morphology and anatomical structures. Twenty mutants hadlow germination rate from 10% to 60%, of which 2 had survival rates at 0% and 50%. Fivemutants occurred structure changes in the hypocotyls or stem. One of these lines, namedarris-stem, showed some unique changes: slower growth rate in comparison with the wildtype from germination to florescence; serrated margin of leaf blades, spiral rosette; morebranch in the bottom part of the stem, shorter nodes, twisted stem and branch. There were oneor several arrises along the stem. Across sections of the arrises showed one or several compactcells lumps which were round, made up of several layers of cells, looked like vascular-bundle.

As one of classical examples of semiactive control system, variable dampers are widely used for structural control.

作为半主动控制系统的经典范例之一，变阻尼控制系统已经在结构控制领域得到了广泛的应用，但是近来的研究显示变阻尼控制对于抑制柔性结构的地震反应是适宜的，而对于刚性结构则是不适宜的。

Fish-bellied cable truss of point supported glazing has been widely used for the characters of lightness and transparency. And commonly it is systematically supported, when additional support is added, the structure is turned from symmetrical support into unsymmetrical support, the mechanical performance will be changed greatly because of its weak ability to resist unsymmetrical deformation, and more discussion will be needed.

点支式玻璃幕墙鱼腹式索桁架结构由于其轻盈、通透的特点得到了广泛的应用，其一般都是对称支承布置，当结构由对称支承变为非对称支承时，由于其抵抗不对称变形的能力较弱，结构的力学性能会发生较大的改变，需要作进一步的探讨。
