So it can be avoided that the computation accuracy is lowered and the calculation result is hard to be convergent for the odd state of transformation matrix.The computation accuracy of wavelet Ritz method and wavelet Galerkin method has been improved so the special'microscopic'property could be fully expressed. An effective method is offered also to solve the problem of high stress gradient and some other odd state problems in engineering.

An improved scheduling method based on exponential division of deadline is presented after study on the problem of prevenient average division of deadline method in this paper.The paper also proves when the relative deadline of each node is too large,the schedular performance of messages transmission task using average division of deadline will be decreased by introducing notion of quantization cost.The new method solves the problem well,and digital simulation validate the new method.

摘 要:针对平均分区的EDF算法在CAN总线中的应用出现的问题,本文提出了一种改进的基于指数分区的EDF算法,并通过引入量化误差的概念,推导证明当CAN网络中各节点相对截至期分布时间过大时,平均分区的EDF算法会导致CAN总线中信息传输任务可调度性的下降,而基于指数分区的EDF算法保证了信息传输任务的实时性,仿真试验验证了算法的有效性。

Benchmark yield curves in the major financial centers had been pushed to quite low levels, setting the stage for a snapback in mature government bond yields when signs of stronger economic growth emerged (Table 1.1). The March 2003 GFSR highlighted the risk that such an increase in yields would trigger an unwinding of carry trades; indeed, the rebound in yields evident in all major markets since mid-June appears to have been accentuated by an unwinding of such trades.

主要金融中心的各种基准收益曲线曾被下降到相当低的水平,为在经济出现更强劲增长时迅速恢复到期的政府债券收益创造了条件(表1--1)。2003年3月份的《全球金融稳定报告》突出了这种收益增长会触发扩大结转交易的风险;确实,现在看来,自6月中旬以来,在所有主要市场上,扩大这种交易加强了明显的收益反弹。

With the idea of smoothing Newton method, we propose a new class of smoothing Newton methods for the nonlinear complementarity problem based on a class of special functions. In this paper, complementarity problem is converted into a series of smoothing nonlinear equations and a modified smoothing Newton algorithm is used to solve the equations. We use Newton direction and Gradient direction together in the algorithm which guarantees that our method is globally convergent. Also using another smoothing function, we reformulate the generalized nonlinear complementarity problems defined on a polyhedral cone as a system of smoothing equations and a smooth unconstrained optimization problem. Theoretical results that relate the stationary points of the merit function to the solution of the generalized nonlinear complementarity problems are presented, we use the modified smoothing Newton algorithm in generalized nonlinear complementarity problems, under mild hypothesis, a global convergence is proved.

本文一方面基于现有的各种光滑Newton法的思想和半光滑理论,利用著名的F-B互补函数的光滑形式,首先将互补问题的求解转化为求解一系列光滑的非线性方程组,然后给出了一种修正的光滑Newton法,该方法不仅放宽对函数F的要求,在Newton方程不可解时引入初始效益函数的最速下降方向,而且光滑因子的选择也比较简单可行,同时在适当的条件下,证明了其算法具有全局收敛性;另一方面,借助另一种F-B光滑函数,将多面体锥上的广义互补问题转化为一种光滑形式,讨论了优化问题的稳定点与广义非线性互补问题的解之间的理论关系,并将这种修正的光滑Newton法用于求解广义非线性互补问题中,在适当的条件下,该算法同样具有全局收敛性。

Inflammation per se may be responsible for mild airflow limitation.7 8 9 Indeed, it has been suggested that inflammation may lead to functional bronchiolar constriction by releasing mediators that may act directly on bronchiolar smooth muscle.10 The chronicity of inflammation would, in turn, produce other changes such as airways fibrosis, and may increase the smooth muscle mass either directly as a result of inflammation or indirectly as a result of chronically increased muscle tone.

炎症本身导致了气流限速轻微下降。而事实上它提示了由于释放的介质直接作用于细支气管平滑肌上,炎症引起了功能性细支气管的缢痕。慢性炎症反多来又会产生气道纤维化等其他改变,这样无论是炎症反应的直接影响结果,还是慢性肌紧张增高的直接影响结果,都会增加平滑肌质量。

The main results were as follows:'Brumal jujube' with higher respiration rate, which decreased slightly after harvest, and lower ethylene production, which had not the appearance of respiration and ethylene production peak, ethephon with different concentrations all increased respiration rate and the respiration rate increased with the raise of concentration ,which suggested 'brumal jujube ' was respiratory non-climactic fruits.

结果如下:冬枣采后果实呼吸强度高并呈平缓下降趋势,而乙烯释放量较低无明显高峰出现;不同浓度的乙烯利处理增加了果实呼吸强度,处理浓度越大,果实呼吸速率越高,说明冬枣为非跃变型果实;1000μL.L~(-1)乙烯利和100mg.L~(-1)ABA处理可显著提高绿熟冬枣采后的呼吸强度,两者无明显差异,但乙烯利处理显著增加了乙烯释放量、ACC含量和ACO活性,其作用比ABA明显;GA处理抑制了果实呼吸强度和乙烯释放量的增加。

The reliability of analysis result depends largely on the in-house experimental conditions. Unlike the previous analysis that only concerns the sole effect of permeable pressure, this article considers both permeable and confining pressure and deformation characteristics of concrete material under the interaction of them according to the real work state of construction, which may leads to the changing pattern of permeable rate as listed below: permeable rate always reaches its peak with the time process going on, than goes down and remains straight on some certain value; The PR will tend to decline while the confining pressure is increased, and the time taken before the peak will be extended as well; Under the constant permeable pressure and circularly changing confining pressure, the minus-exponential ascend and descend relationship could be applied between the PR and Time axes respectively with crannied and intact concrete samples, and the PR of crannied concrete is far more larger than that of intact concrete. The change pattern of concrete could also be mathematically analogized using the least square method.

室内的实验条件是研究成果可靠性的重要因素,而以往的研究都只考虑了渗透压单一作用,本文根据混凝土结构的实际工作状态,同时考虑了围压与渗透压共同作用下的混凝土材料的渗透性变化特征,得出了混凝土材料在围压作用与渗透压共同作用下的渗透率的变化规律:渗透率都是随时间推移先达到一个峰值,再降低并趋于平稳;渗透率会随围压的增大而减小,并且峰值的到达时间也会随之延长;在渗透压不变,围压升降循环的情况下,有裂缝、无裂缝混凝土的渗透率变化规律是随时间成负指数关系上升、下降,且有裂缝混凝土试件的渗透率远远高于无裂缝混凝土的渗透率,并对混凝土的变化规律运用最小二乘法进行数学拟合。
