利用反荧石结构和其结构的相似性，确定了Na2KSb、Cs3Sb和K2CsSb阴极在光谱结构上对应布里渊区中发生的光学跃迁，发现多碱阴极的跃迁更接近晶态，而Cs3Sb和K2CsSb阴极和非晶态的非常类似，在Na2KSb中出现的来自Δ、Σ方向跃迁形成的极大峰并不出现在Cs3Sb和K2CsSb。

With the increasing of the concentration of alkali, the content of insolubility of the product reduces initially but increases later, the DS of product increases initially then reduces later. The product has good solubility and high DS at 10% content of alkali. The insoluble product reduces at initially and then keeps stability later with the time of basification extending. With the increasing of the content of water in system, theinsolubility of the product reduces initially and then increases later.

随着碱浓度的增加，产物中水不溶物含量先降低后增加，取代度先上升后下降，在10％时，水溶性最好，取代度最高；延长碱化时间，产物中水不溶物含量下降，之后趋于稳定；提高反应体系中水的含量，产物中水不溶物含量先降低后增加，在7％时，水溶性最好，延长分散时间，产物中水不溶物含量下降，取代度提高；醚化剂以少量多次的方式滴加，产物水溶性好。

Moreover, the inner cone has the characteristic of Lewis basis with high electron density because of the lone-pair electrons of oxygen atoms stretching towards it and can form inclusive compounds with varied compounds. The special structure of CD is very important to separate and analyze enantiomers, which has become the most important mainbody of super-molecular chemistry and greatly improved the developments of bioscience and pharmaceutical chemistry.

Daxing as the case study has been studied in this dissertation, with the help of geostatistics and GIS, on the basis of data of the second general soil quality investigation in 1982 and the corresponding data of indoors soil analyzed, the spatio-temporal law of organic total-N, hydrolyzable nitrogen, available-P and available-K below the surface of soil (0-20cm) within 20 years in Daxing has been studied, as the same time, the change of soil quality has been evaluation applying to the method of soil quality compressive index, the main results are as follows

本文以北京市大兴区为研究样区，以相同样点的1982年第二次土壤普查土壤肥力数据和2000年的新采土样分析数据为基础，运用GIS与地统计学结合的方法，研究了20年来北京市大兴区300多点位的表层土壤的(0-20cm)有机质、全氮、碱解氮、速效磷、速效钾等肥力要素的时空变化规律，应用土壤质量综合指数法定量评价了表层土壤质量的变化，研究主要结论如下

The alkali lignin-based rigid polyurethane foam was prepared with alkali lignin extracted from black liquor as raw materials to replace 10%~25% amount of polyether polyols and polymethylene polyphenyl isocyanate.

以造纸黑液中提取的碱木质素为原料，代替10~25的聚醚多元醇与多亚甲基多苯基多异氰酸酯合成了碱木质素基硬质聚氨酯泡沫。

Abundance orA repeats was similar to C repeats. AC was a little more than two times as abundant much as AG. However, AT and CG repeats were rare. For tri- and tetramer repeats, AGC,AAAC and AAAT predominated while ACG, ACT, AGG, CCG, ATGC, CCCG, ACTG, AACT, ACGT, AGAT, CCGG,ACCT and AGCT were rare. For some pentamer repeats, one was completely absent on a certain chromosome, even on several chromosomes.

对按蚊基因组中微卫星丰度而言，A碱基和C碱基重复在基因组中丰度相似，AC单元的丰度是AG单元的两倍多，然而AT和CG单元非常稀少；对于三四碱基而言，AGC，AAAC和AAAT单元最为丰富，ACG，ACT，AGG，CCG，ATGC，CCCG，ACTG，AACT，ACGT，AGAT，CCGG，ACCT和AGCT单元等均很稀少，而一些五碱基重复，在某条甚至某几条染色体中均未分布。

Multilayer latex particles with carboxylic polymer as core, polymer with low glass transition temperature and film-formable under room temperature as shell, and lightly crosslinked polymer as intermediate layer were prepared with unsaturated carboxylic monomers by multistage seed emulsion polymerization. Finally, the room-temperature-film-formable polymer particles with hollow structure were obtained via the alkali treatment to the multilayer latex particles.
