Copper fixation rate affected by retention, fixation time, ligand type, and addictive. For all formulations, while other three conditions is the same, copper fixation rate of preservatives with low retention level is less than those with higher retention level; copper fixation rate of oven-dried bamboo samples is less than air-dried bamboo samples; copper fixation rate of amine-based preservatives is less than ammonia-based ones; copper fixation rate in some formulations containing carbonate and phosphate is higher than non-carbonate and non-phosphate ones.

在其它条件相同时，高吸药量时防腐剂的固着率明显高于低吸药量时的固着率；固着时间长的试样比固着时间短的试样具有更高的铜固着率；以氨水作配体的防腐剂固着性高于以乙醇胺作配体的；碳酸盐和磷酸盐在某些配方中能够改善防腐剂固着性。

Considered that china finance reality, implementing hard peg exchange rate regime isn" t favor to economic level effect, but at present there isn" t enough condition in implementing float exchange rate regime in china, so author argue that china should choose median exchange rate regime between hard peg exchange rate regime and float exchange rate regime.

论文重点分析了在中国金融进一步开放中，实施固定汇率制不利于发挥汇率的经济杠杆作用，而实施浮动汇率制的条件又不具备，只能选择介于固定与浮动两极之间的&中间汇率安排&。

Results indicated that according to the different newly increased cultivated land rate, land consolidation projects on the district or county level could be divided into four categories: land consolidation, cland consolidation and exploitation, land development and consolidation, land development. While according to the investment per unit area on newly increased cultivated land, it could also be divided into four categories: high investment, reasonable investment, partial low investment and low investment. Correlating curve type among the investment per unit area in newly increased cultivated land, average annual growth rate of GDP and average annual growth rate of per capita GDP was a compound one. Correlations among newly increased cultivated land investment per unit area and annual growth rate of per capita GDP, annual growth rate of per capita GDP and other economic development indexes showed an "S" changing tendency curve.

It is believed that the answer could be found out through estimating the natural rate of unemployment. Seeing that the researches into the reasons of Taiwan's natural rate of unemployment and into the correlation of this natural rate and monetary policy are extremely rare, at the time when real unemployment rate climbs significantly, it would be valuable to re-estimate Taiwan's natural rate of unemployment and explore the potential factors.

上述问题，可透过自然失业率之估计加以探讨，且由於探讨台湾自然失业率变动之背后原因及其与货币政策间关联性之研究相对付之阙如，值此实际失业率攀升之际，吾人认为对台湾自然失业率之重新估计与深入探讨自然失业率变动之影响因素均具价值。

The method to configure RED parameters based on network properties is also presented. Simulations show that the modified Random Early Detection algorithm really performs better than the original Random Early Detection algorithm and can work for a much wider range of traffic. Finally, whether the assured service mechanisms i. e. an edge router tags every arriving packet of a TCP flow based service profile and core router drops packets differently at congestion using active queue management scheme is possible to provide a throughput consistent with target rate, is investigated under different network scenarios. Different factors including target rate tagged algorithm, RIO algorithm and TCP congestion control mechanism how to affect the throughput of an assured service TCP flow are examined. Based on a fluid model. we then derive a model of an assured service TCP flow, which is the function of round trip delay, packet loss rate and token bucket parameters. Based on this model, we observe that in some cases it is possible to regulate the token bucket parameters to gain a consistent throughput with the target rate, while in other cases there exist ranges of values of the achieved rate for which the token parameters have no influence. With the latter, some modified TCP congestion control mechanisms to assure TCP throughput are proposed.

最后，在区别服务网络结构内，研究了当前提出的一种边缘路由器根据服务合同标记、分类数据包，结合内部路由器采用主动队列缓冲管理机制区别处理数据包的确信服务机制是否可在不同网络情况下使TCP连接获得同目标速率相一致的、公平的吞吐量问题；指出影响TCP连接获得同目标速率相一致吞吐量的主要因素是目标速率大小、标记算法参数和TCP连接的拥塞控制算法；对此，基于流模型假设，首次推导出一个以端到端时延、数据包丢失率、漏桶参数为变量的确信服务TCP连接吞吐量模型；利用这个模型进行分析，得到主要结论是在一些情况下可通过设置合适的漏桶参数得到同目标速率更一致的吞吐量，而在另一些网络情况下不管如何设置漏桶参数都不能使TCP连接获得同目标速率一致的吞叶量；对于后一些情况，还初步讨论了改进TCP拥塞控制算法来改善TCP连接性能的方法。

At present,the rate laws and reaction mechanisms of pyrite oxidation,pyrite and chalcopyrite formation,uraninite and magnetite dissolution in aqueous solutions are mainly studied,and it is discovered that (1)oxidation rate of pyrite controlled by surface reaction assume fractional dependence on Fe3+ and O2 molalities in acid solutions;(2)Pyrite cannot nucleate directly from solutions below 300 ℃,it can only form initially through sulfidation of a FeS precursor. The rate equation of reaction between FeS and H2S to form pyrite is of the second order;(3)Chalcopyrite is formed by reactions of pyrrhotite or pyrite with Cu2+,the former proceeds via a series of mediate metastable phases of Cu-Fe sulfide,whereas the rate equation of the latter is apparently of the first order which is controlled by surface reaction;(4)The nonlinear behavior of magnetite dissolution at acid pH can be represented by a shrinking core model coupling with surface reaction and diffusion transport.

目前主要研究了水溶液中黄铁矿氧化、黄铁矿和黄铜矿形成、晶质铀矿和磁铁矿溶解的速率定律和反应机理，发现：(1)酸性溶液中黄铁矿的氧化速率对Fe3+和O2浓度呈分数依赖并受表面反应的控制；(2)低于300 ℃时黄铁矿不能从溶液中直接成核，而需初始地通过FeS先驱物的硫化生成，FeS与H2S反应形成黄铁矿的速率方程为二级；(3)磁黄铁矿或黄铁矿与Cu2+反应均可形成黄铜矿，前者经历了一系列准稳的Cu-Fe硫化物的中间物，后者的速率方程为表观一级并受表面反应的控制；(4)酸性pH时磁铁矿的非线性溶解行为可采用表面反应扩散输运耦合的收缩核模型来描述。

Every treatment combination has 4 replications.(1)The germination indexes of the former are higher than that of the latter; the germination of the former is stimulated by NaCl density of 0.3 %, while that of the later is restrained by all kinds of NaCl density.(2)With increasing of temperature and PEG indesity,the order of germination rate and vigor of Bromus stamineus and Bromus inermis is decreaced.(3)Under treatment of broadcast sowing and plant density of 549kermels·m~(-2), Bromus stamineus has the highest bud rate, fresh weight, seed yield, while treated with 25cm row spacing and 412kermels·m~(-2) plant densities, tillers, plant height, growth rate increased to the top;(4) Under treatment of broadcast sowing and plant density of 549kermels·m~(-2), its growth rate is took second place, while treated with 15cm row spacing and 824kermels·m~(-2) plant densities, it has the highest seed yield

Another result of the study is that the total rate of entering a higher school is 74 percent, 69 percent, and 86 percent. For educational opportunities, the second group is most unequal when the rate of entering a higher school increases up by 50 percent. Through the analysis of logical regression beta b, the change in the inequality of opportunities of years of education in Taiwan is mainly influenced by various sharp structures of a total rate of entering a higher school, and not by the inequality of educational resources. When the rate of entering higher school is nearly 50 percent, the opportunity of years of education is most inequal.

本研究进一步分析各年代的整体国中后升学机率，分别为74%，69%，86%，以第二组年代的升学机率最接近50%，教育机会也最不均等；而根据逻辑回归系数 b 值的分析结果，发现台湾地区民众教育资源分配之不平等性并没有明显一致的变化趋势，前述受教育年数的机会不平等性之变迁，并非受教育资源分配不平等性的影响，而主要受到整体升学率不同的钜视结构影响，在升学率最接近50%时，受教育年数的教育机会最不均等。

During the non-isothermal crystallization, compared with common PE, the cooling rate had less impact on the crystallization rate of mPE. Second, the sensitivity of the melt viscosity of mPE to the shear rate was poor, and the introduction of long chain branches onto the molecular structure of mPE could improve the dependence of their melt viscosity on both shear rate and temperature. In the extensional rheometric tests, the occurrence of phenomena of'strain hardening' relied on the structure of linear long chains, and mPE didn't show the behavior of'strain hardening', which implied that the melt strength ofmPE was poor.

其中通过共聚方法在mPE分子中引入非线性长支链结构，对提高mPE熔体粘度对温度的依赖性作用较为明显，而对提高mPE熔体粘度对剪切速率的依赖性以及对提高mPE熔体强度作用较弱；采用共混方法在mPE体系中引入线性长支链结构，则对提高mPE熔体粘度对剪切速率的依赖性以及提高mPE的熔体强度的作用较为明显，而对于提高mPE熔体粘度对温度的依赖性作用相对较弱。
