At the same time, the finite staff element method is used to analyze the influence of beam rigidity; and the two new methods proposed are used to analyze the influence of connect way between piles and beam; and the conclusion is obtained that the rigidity ratio between beam and piles being 0.48 is appropriate; the continuative increase of the rigidity ratio is not significant; the worst condition is that connecting way between piles and beam is hinged; the best condition is that connecting way between piles and beam is rigid. Whether is single-row pile or are double-row piles, when the front of single-row pile or the front of the front-row pile(in the double-row piles) needed excavation, it is supposed to that ought to be carefulness to excavate, because it is that the engineering cost increased greatly.

同时，用有限杆单元法，对双排桩的连梁刚度和用文中提出的方法以桩梁连接方式进行了试验和理论分析得出如下结论：在满足不相互影响排桩间距的情况下，桩顶连梁与桩的刚度比不小于0.48是合适的，此时再增加连梁刚度无意义；桩梁连接为铰结时双排桩受力变形性质最差，刚结时受力变形性质最好；不论是单排桩还是双排桩，桩前和前排桩桩前土体需要开挖时应慎重，因为这种开挖对支护结构影响很大，造价增加很多；双排桩省钱，而且抵抗变形的能力强，值得在工程中研究和广泛应用

Based on these, an improving μ-synthesis is presented, with which the high-purity distillation is designed well. 2. The robust performance problem of MIMO plant is explained with the plant direction angle, which shows that the robust performance varies with different input uncertainties and the μ-synthesis should be applied correctly according to the uncertainty structure. 3. Condition number and bandwidth are the important items for robust performance design in MIMO system. The H〓 two-block problems can not deal with the robust performance design of MIMO system because of the condition number cancellation. A general μ-synthesis procedure for MIMO system with uncertainties is presented. 4. For the SISO system, the object function in robust performance is amplified by at most 〓 than that of H〓 two-block problems in value: So the robust performance of SISO system can be done with the H〓 two-block problems to avoid the complicated μ-synthesis procedure. 5. All the conclusions and methods presented in this paper are demonstrated by some typical design examples.

It proves that tree top leaves suffer from water stress and hydraulic limitation becomes greater with tree height.Water stress influence tree height growth in several aspects:firstly is the influence of exterior water condition,and community average tree height is positive with exterior water condition.Secondly, hydraulic limitation influences individual tree structure and function.Xeromorphic structure,Lower water potential and turgor pressure limit cell division and expansion,which restrict gas exchange and carbon assimilation capability.However,respiration consumption increases with the spread of tree crown.Shortage of nutrient limits carbon investigation on new leave growth and may ultimately limit tree growth.Thus,the main limitation of tree height is water.

水分对树高生长的限制首先是外在的水分状况，群落的总体高度随外界水分状况的变差而变矮；再就是水力限制对单株树木的结构和功能的影响，水势降低、膨压减小使细胞的分裂和扩展受限，旱生型结构加剧水力对气体交换能力的限制、使光合碳同化能力受到限制、而呼吸消耗却随着树木个体的增大而增大，制造营养物质不足、使得营养亏缺、造成投入新枝叶的营养受限，最终限制了树高继续增长。
