The dissertation focuses on performance gradient estimation and SRO algorithm of DES aswell as other related topics,such as modeling of DES and discrete event simulation,performancemeasure Hessian matrix estimation,Stochastic Approximationand so on.General Semi-Markov Processis adapted to describe behaviour of DES and discrete eventsimulation.A general result is obtained and applied to analyze strong consistency of performancegradient Perturbation Analysisestimator.Conditions for effectiveness of InfinitesimalPerturbation Analysisare also discussed.New PA algorithms,such as server PA,PA usingDirac generalized function,job sequence PA etc.,are proposed to deal with discreteparameters.Furthermore,strategies of combining PA algorithms with certain iterative rules areanalyzed widely in order to optimize DES parameters and some SRO algorithms are constructed toslove DES optimization problems.

It is included that 4-5 types of active sites exist in the catalytic system and the active site produced polymer with low molecular weight is easy to be activiated while TEA is used as the cocatalyst. While TIBA, the active site produced polymer with high molecular weight and seldom active site produced polymer with low one is prone to be activiated. MAO tends to activiate the active site produced polymer with middle-level molecular weight. In TEA-TIBA catalytic system, TEA and TIBA activiate the corresponding active site and the weight of every active site gradationally varied with the change of the ratio of the two cocatalysts. And the activity of the active site produced polymer with high molecular weight is proportion to the concentration of TIBA.

发现：TEA作为助催化剂时产生低分子量产物的活性中心易于活化，且体系中具有活性的活性中心有4～5种；TIBA易于活化产生高分子量的活性中心，基本上不能活化产生低分子量产物的活性中心；MAO对产生中等分子量产物的活性中心活化能力较强；在TEA-TIBA混合物体系中，TEA和TIBA各自对活性中心的作用表现为明显的互补现象，各活性中心的相对强度随着两种助催化剂之间的比例改变呈现渐次变化，其中产生高分子量产物的活性中心的相对活性(来源：c5AB3fC论文网www.abclunwen.com)与TIBA的浓度有明显的正相关性。

Therefore, fish's predatory control on zooplankton is higher in shallow lakes, resulting in less possibility of grazer control of algae by the Cladocera.

下行效应在浅水湖泊中可能更为重要，因此浅水湖泊中滤食性鱼类对浮游动物的捕食控制可能更强，导致枝角类几乎不可能通过牧食控制藻类的生长。

Arginine is also the most basic natural amino acid due to its extremely basic guanidine side chain.

In Chapter One,we find the relationship between strong open set condition , Hausdorff dimension,the positivity of the Hausdorff measure and β space of graph-directed self-similar sets in complete metric spaces.

In classifier 3, HAVNET is used as the first stage and a multilayer neural network as the second. HAVNET is a kind of binary pattern classifier, which employs Hausdorff distance as similarity metric. The network architecture is flexible enough to incorporate self-supervised learning, self-organization, and competitive learning as required by specific application.

HAVNET是以Hausdorff距离为相似性度量的二值模式分类器，其网络结构具有相当的灵活性，可以在训练过程中采用自监督、自组织和竞争学习，在网络中用独立的通道表示一个类别中的各子类别模式，该特性使HAVNET在实现模式识别任务时，具有较强的可行性。

The results showed that the number of haustorium of P. striiformis in AQ and LB was 44.2/mm2 and 23.74/mm2 respectively. But there was no difference with the number of hastorium of the pathogen between XN (89.83/mm2) and MX (102.02/mm2), which indicated that XN had no resistance to haustorium.
