The results show that when alkaline earth metal oxides are used as the medium, the products are hexacoordinate silicon complexes, and that under the optimum synthetic conditions, the conversion yields of barium salt and calcium salt are greater than 90% and 60% respectively.

结果表明：以碱土金属氧化物为介质时，合成产物为六配位体有机硅化合物；在最佳合成条件下，钡盐的转化率达90%以上，钙盐的转化率在60%以上。

The resolution is improved through optimal combination of bin attributes which are small offset, small bin, wide azimuth, large off-inline distance and high coverage. Then the "feature net" of near surface conditions was created, and the "sudden transition" of near surface variations was found to provide reliable foundation for optimum shooting parameters selection. The effective methods of spectrum analysis were generalized. It is concluded that the target is satisfying sand body interpretation, not pursuing high frequency.

通过较小炮检距、较小面元、较宽方位角、较大非纵距和较高的纵、横向覆盖次数等面元属性的优化组合，提高了该区地震资料的分辨率；建立了表层条件&特征网&，通过寻找表层变化&突变带&，可为最佳激发因素的选取提供可靠依据；总结了频谱分析的有效方法，提出要以砂体解释的需要为目标，避免陷入盲目追求高频率的误区。

The effect of mesh TiO〓/Ti used to treat rhodamine B and rose bengal was equivalent to that of 0.1～0.3％ TiO〓 suspensions, it indicated that the photoelectrocatalytic oxidation system of mesh TiO〓/Ti could replace the system in above concentration condition basically. The content, which is similar to the result of this study, has not been reported in present domestic and oversea researches of fixed TiO〓 catalysts.

用丝网TiO〓／Ti催化剂光电催化降解若丹明B和虎红，其处理效果相当于TiO〓浓度为0.1-0.3％的悬浆体系，表明以丝网TiO〓／Ti为催化剂的光电催化氧化体系基本上可以代替上述浓度条件下的TiO〓悬浆体系使用，在目前国内外固定态TiO〓催化剂研究中，尚无类似报道。

In order to solve the problem of Botryosphaeria dothidea on resistance to traditional fungicides, bio-assay tests were made for 6 fungicides including 10% water-dispersible granules of difenoconazole, 250 gL^(-1) azoxystrobin suspension concentrate etc. against B. dothidea in laboratory. Field tests of these fungicides with different concentrations were made for control of the disease on apple trees.

为解决当前苹果轮纹病对传统药剂产生抗性问题，以70%代森锰锌可湿性粉剂为对照，在室内测试了10%苯醚甲环唑水分散粒剂，250gL^(-1)嘧菌酯悬浮剂等6种化学杀菌剂的室内毒力；另外在田间设置小区试验，测定了这些药剂在不同使用质量浓度条件下对苹果轮纹病的防治效果。

In chapter3, information is divided into two basic types, the marginal equation of bond price and short-term interest variations is established, thus the security price variations and the price equilibrium of other assets (risk security non-risk security are included) are analyzed by the implement of portfolio Theory.

第三章将债券的价格均衡划分为两大基本类型，建立了债券与短期利率变动的边际方程，运用组合原理分析债券价格变动与其它资产（包括风险证券和无风险证券）的价格均衡关系，通过比较收益原理建立了债券以市场均衡收益为折现参数的价值方程，并通过实证检验了该模型的合理性；第四章，分析了内部信息与价格的传导原理，建立了非完全信息市场条件下价格传递信息的做市商模型和预期模型，并讨论外部信息与内部信息对股票价格影响的非一致性。

In chapter3, information is divided into two basic types, the marginal equation of bond price and short-term interest variations is established, thus the security price variations and the price equilibrium of other assets (risk security non-risk security are included) are analyzed by the implement of portfolio Theory. Finally the bond value equation which takes equilibrium return as its yield Parameter is established through the theory of comparative return. In chapter 4, the intra-information and the transferable system of price is emphasized and the market-maker model and expected model under non-perfect information market conditions are established, and the disaccord of the influence of extra-information and intra-information on the security price is discussed.
