论文以解决陕北地区的收入问题，植被问题以及粮食产量问题为出发点，首先从理论上分析了包络分析方法在陕北地区退耕还林中运用的可行性，然后结合陕北地区目前的实际情况，综合分析出影响陕北地区退耕还林的关键的七个因素作为输入指标：水利水保设施投入，农作物投入，经济林种支出，防护林支出，其它经济作物，草类支出，畜牧业投入；以退耕还林所要解决的最终问题作为输出指标：GDP收入、农民人均纯收入、水土流失减少量、牧业总产值、粮食产量、林业总产值、其他经济作物总产值。将各指标所对应的数据代入模型后，通过分析求解得出非有效的决策单元，再运用包络分析方法的一些基本原理对非有效的决策单元进行调整，由此所得的数据对陕北地区的实际投入具有很好的指导意义。同时，又针对陕北地区在退耕还林过程中以及之后可能面临的困境，提出了一些建议和对策。最终使得陕北地区的投资环境尽快得以改善，使农民尽快脱贫致富，使人口、资源、环境的关系尽快纳入良性循环的轨道上。

The average percentage of polymorphic bands are 72.06% for ISSR and 66.67% for RAPD respectively. The genetic diversity of ginkgo revealed by ISSR (the average effective number of alleles is 1.8780, the average Nei"s gene diversity is 0.4652, and the average Shannon"s information index is 0.6574) are all higher than those by RAPD (the average effective number of alleles is 1.7842, the average Nei"s gene diversity is 0.4317, and the average Shannon"s information index is 0.6211), while the standard errors of the parameters estimated by ISSR were lower. Therefore, ISSR molecular markers are more suited than RAPD molecular markers when testing the genetic diversity of ginkgo populations and determining the genetic relationship of among populations or among individuals which are much similar hereditarily.

本文应用RAPD和ISSR两种分子标记技术，选取中国5个可能的野生银杏居群共计75个样品，对其遗传多样性进行了研究，得出以下结论：(1)用筛选出的12个RAPD引物和10个ISSR引物进行PCR扩增，分别扩增出65条和68条重复性高、清晰的条带，多态性位点百分率分别66.67%和72.06%，ISSR揭示的银杏遗传多样性(平均有效等位基因数目为1.8780，平均基因多样度为0.4652，平均信息指数为0.6574)高于RAPD所得到的结果(平均有效等位基因数目为1.7842，平均基因多样度为0.4317，平均信息指数为0.6211)，其所估算参数的标准差要低于RAPD所估算出的值，因此，在研究亲缘关系非常近的银杏物种的遗传多样性并试图确定居群间或个体间的遗传关系时，ISSR分子标记技术比RAPD分子标记技术更为合适。

Good thermal stability and self-extinguishing behavior was observed with the cured polybenzoxazine resins. Second, furan-containing benzoxazine monomers, P-FBz, BPA-FBz, and 4FP-FBz were prepared using furfurylamine as a raw material. Formation of furfurylamine Mannich bridge networks in the polymerizations of P-FBz and BPA-FBz increased the cross-linking densities and thermal stability of the resulting polybenzoxazines. P-FBz and BPA-FBz- based polymers also exhibited high glass transition temperatures above 300℃, high char yields, and low flammability with a limited oxygen index value of 31. The dielectric (Dk3.21–3.39) and mechanical properties (high storage modulus of 3.0–3.9 GPa and low coefficient of thermal expansion of 37.7– 45.4 ppm) of the P-FBz and BPA-FBz-based polymers were superior or comparable to other polybenzoxazines. 4FP-FBz used for polybenzo- xazine modification by means of formation of benzoxazine hybridation with P-FBz.

第二部份以2-呋喃甲胺为起始物，制备了P-FBz、4FP-FBz与BPA-FBz 三个含呋喃官能基之氧代氮代苯并环己烷的单体；BPA-FBz与P-FBz於开环聚合中形成之Mannich bridge网状结构有效地提升聚氧代氮代苯并环己烷聚合物之交联密度与热安定性；Poly与Poly具有大於300℃之玻璃转移温度、高的焦炭生成率与具有31之极限氧指数(Limited oxygen index， LOI)的难燃性特质，Poly与Poly之介电常数(Dk=3.21~3.39)与机械性质[3.0~3.9 GPa的储存模数与37.7~45.4ppm之低热膨胀系数( Low coefficient of thermal expansion， Low CTE)]均较其他聚氧代氮代苯并环己烷为优；4FP-FBz具有低之介电常数(Dk=2.7)，以其作为降低介电常数之反应型改质剂，与P-FBz混成，证实可有效地降低Poly的介电常数。

The empirical result demonstrates that:(1) the average abnormal reture and accumulated average abnormal reture around and after quarter surplus announcement change obviously, which illustrates the quarter surplus reports are of information content in our A share market;(2) the market can treat different types of accounting surplus data distinguishly by analysing inexpectant surplus as good news or bad news, but it reacts intensely to good news and flatly to bad news:(3) the market investors are paying more and more attention on accounting surplus of listed companies, which can be viewed in the annual text that the surplus reaction coefficient significance enhances;(4) A share market is, basically, under a state of semi-strong efficiency, or at least of an effective process from weak to semi-strong.

实证结果表明：(1)季度盈余报告公布前后平均非正常收益率和累积平均非正常收益率都发生了明显的变化，说明在我国A股市场季度盈余报告是具有信息含量的；(2)通过对未预期盈余分为利好组和利空组的分析，得出市场能够区别对待不同性质的会计盈余数据，但是市场对利空消息反应强烈，对利好消息反应平淡；(3)在分年度的检验中，可以看到盈余反应系数的显著性不断增强，证明我国A股市场的投资者对于上市公司会计盈余的重视程度在不断增加；(4)研究结果倾向于我国A股市场基本处于半强式效率，至少我国证券市场正处在从弱式有效向半强式有效转变的过程中。
