In Chapter 5, photo-induced absorption is used to study the intersystem crossing from singlet to triplet states of two polyfluorenes after doped with Ir-complex. It is found that the triplet exciton lifetime of PFs is reduced by the dopants. But instead of decreasing, the population density of PF triplet exciton increases by almost one order of magnitude. The finding shows that the ISC rate can increase over 100 times due to the spin-orbital interaction with the Ir ions.

第五章以光诱发吸收光谱技术研究两种聚芴高分子掺杂绿光铱错合物后，聚芴的单重态到三重态的内部系统转换效率的改变；研究发现在掺杂后，聚芴的三重态生命期减短，但出乎意料的是其三重态的态密度并没有随之降低反而有一个数量级的增加，其原因为单重态到三重态的内部系统转换受铱错合物的影响效率增加了100倍。

Therefore,tapping potencial of remaining oil to improving oil recovery,the recognition of reservoir intraformational heterogeneity in channel sandbodies is proposed and the main targets of reservoir IOR in channel sandbodies of mature oilfields are pointed out as follows:①shutting off strongly-waterflooded intervals to control ineffective circulation of injected water;②strengthening water washing in medium-waterflooded intervals in order to achieve the aimed waterflood efficiency and even to exceed it;③enhancing injection-production consistency and injector-producer ratio of non-waterflooded or weakly-waterflooded intervals for the propose of realizing effective displacement and imporving conforma nce.

根据我国东部主力油田储层绝大多数都属于河道砂体，注水开发进入高含水阶段后，层内剩余油超过层间剩余油，层内矛盾上升为主要矛盾这一特点，从挖掘层内剩余油潜力出发，提出要重新认识河流砂体储层层内非均质性，并指出高含水期河流砂体储层改善采油目标主要有：①封堵强水洗段，控制注入水无效循环；②加大中水洗段注水冲洗强度，达到目标水驱效率，并有可能超过目标效率；③提高未、弱水洗段的注采对应程度和注采井数比，达到有效驱替，提高波及程度。

Moreover, high TONs (turnover numbers, TONs up to 1 000 000 for the reaction of iodobenzene with phenylboronic acid) for the palladium-catalyzed Suzuki-Miyaura cross-couplings were observed

同时，这种催化体系还可以达到很高的催化效率(碘苯和苯硼酸的催化效率甚至可以达到1000000)。

It is reported that in china irrigative water use efficiency is only 0.4 ,and that water use efficiency of crops is 1 kg/m3; and is only half of developed country, thus it can be seen that the key of saving agricultural use water is to how to increase crops use water efficiency .

我国灌溉水利用系数仅为0.4，农作物水分利用效率仅为1kg／m~3，是发达国家的一半，由此可见发展节水农业的关键是提高农作物的水分利用效率。

In the second trial, five groups of diets with isonitrigenous (40% protein) and isoenergetic 20 MIJg^(-1 gross energy and different relativity of essential amino acid balance with soybean protein replacing 0.0%, 13.5%, 27.0%, 40.5% and 54% of fish meal protein, were formulated to determine optimal replacement level of soybean protein to fish meal protein.

实验Ⅰ以褐鱼粉为蛋白源，配制5个蛋白水平(31.04%、35.51%、40.89%、46.62%、50.33%)的等能、等必需氨基酸平衡关联度的半精制饲料，探讨翘嘴红鲌对饲料蛋白的需求；经过8周饲养，实验Ⅰ的结果表明，饲料蛋白含量对翘嘴红鲌的增重率、饲料效率和蛋白效率具有显著影响。

Calculation showed t hat corrosion inhibition increased with the decrease of negative net charge of N atom; Efficiency of inhibition increased with the increase of negative net char ge of pyridine ring in isoquinoline molucular.

计算表明：随着N原子负的净电荷的减小，缓蚀效率提高；随着异喹啉等分子的吡啶环负净电荷的增大，缓蚀效率增高。

Different from current jurisprudential methods, this dissertation tries to expand the studies on the rule of tax law through economic methods.

与一般的税收法治研究采用法学分析方法不同的是，本文以经济学的方法来分析税收法治，并将研究主题界定为权力的结构与公共产品的配置效率以及经济效率之间的关系。

The system applies the popular DBF and ORACLE,solves many questions such as inefficiency,low reliability during the management land information,fulfills the scientific,modern,standard and latticing management,gets the aim to share information and save cost,and meets the requirement of the dynamic management and the application on oilfield land information.

该系统应用流行的 DBF和 ORACLE数据库管理，解决了土地信息管理工作中存在的效率低、可靠性差等诸多问题，实现土地信息管理工作的科学化、现代化、标准化、网络化，达到信息共享、节约费用、降低工作强度、提高工作效率的目的，满足了油田土地信息的动态管理与应用要求
