Moreover,it was demonstrated that the threesubstances,E,DE and DA,increased dramatically and quickly after LPS treatment.Also,it was revealed that the changes of three substances were more quickly than thechanges of the above mentioned APPs during the same LPS treatment.Thesesuggested that the three substances existed as neurotransmitter.The presence and thechange of the CAs in amphioxus after treated with LPS indicated the evolutionaryexistence of CAs and acute phase response in the protochordate lineage.

第四，我们用高效液相色谱法(High Performance Liquid Chromatography，HPLC)，探讨了LPS感染文昌鱼儿茶酚胺类神经递质的变化，优化了同时测定文昌鱼体液中NE、E和DA三种CAs的HPLC方法，并首次发现，文昌鱼体液中同时存在NE、E、和DA三种CAs物质，其中，E在文昌鱼中首次报道，这三种物质在LPS感染文昌鱼后浓度升高非常明显，与同期的APPs相比变化更为迅速，也体现了神经递质的主导作用，文昌鱼的CAs系统也具有了类似脊椎动物CAs系统的功能，可以初步判断CAs系统的进化源头由脊椎动物可推回到头索类。

In thesecond chapter, eleven 1,3,4-oxadizoles bearing chiral pyrazolyl moieties(4a-k) andfive triazolotriazines bearing chiral pyrazolyl moieties(5a-e) were obtained from5-[(1"S)-1",2-diacetyl-oxyethyl]-1-phenylpyrazol-3-carboxaldehyde(1) with arylcar-bohydrazide or (5-aryl-1,2,4-triazin-3-yl)hydrazine through an intramolecular1,3-dipolar cycloaddition in the presence of the non-metal oxidant IBD.

其中第二章介绍了以D-葡萄糖为原料制得的5-[(1′S)-1′，2′-二乙酰氧基乙基]-1-苯基吡唑-3-醛(1)分别与芳基甲酰肼、(5-取代苯基-1，2，4-三嗪-3-基)肼反应，在无金属氧化剂—IBD引发下，发生分子内1，3-偶极环加成，采用&一锅煮&法合成了11种含手性吡唑基的1，3，4-噁二唑类化合物(4a-k)和5种含手性吡唑基的三唑并三嗪类化合物(5a-e)。

Two sorts of polyacrylate derivates were designed and systhesized. One has benzoic acid groups linked to backbone via an alkyl chain of different length, the other has pyridyl groups at its side chain. On the basis of hydrogen-bonding between carboxyl and pyridyl groups, multilayer film was fabricated in mixed solvents. We studied the effect of either the composition of mixed solvents or length of alkyl chain on the structure of a multilayer film.

设计合成了两类聚丙烯酸酯类高分子，一种侧链含有通过不同个数的亚甲基和主链相连的苯甲酸基团，另一种侧链含有吡啶基团，基于羧基和吡啶基之间的氢键相互作用，在混合溶剂中制备了多层膜，并研究了溶剂组成与高分子侧链间隔基长度对多层膜结构的影响。

We explore the relation between structure and activity , structure and toxicity from electronic structure and three—dimensional conformation in order to provide theoretical foundations for predicting the activity and toxicity of these chemical compounds, researching into mechanism of action and choosing safener.

通过比较四种均三氮苯类除草剂的红外光谱特征吸收的实验值和计算值，并运用规范不变原子轨道法GIAO法在RHF/6-31G水平上计算出西玛津的δ~1H-NMR和δ~(13)C-NMR，与实验值的对比统计分析，结果表明：用RHF/6-31G优化的分子构型最佳，AM1法次之，考虑到优化时间和研究的需要，我们在研究均三氮苯类除草剂分子的结构与活性关系时，为了进行深入、精确的理论研究，采用从头算RHF/6-31G进行优化；而对于此类化合物的结构与毒性的关系研究时，更注重分子的量子化学参数的相对值而非绝对值，因而采用AM1的方法。

He does not say what he thinks being transcendental means, and he says he is not going to consider 'whether, in general, such a form of argument is permissible or fruitful'.6 He says the argument is also transcendental in another (presumably non-Kantian) sense: in proving the existence of a class of entities different in kind from 'sensa'.

他并没有说他怎么看先验论证，他说他不打算考虑&总的来说这么种论证是否可行或有所收获&。他说这类论证亦是另外一种意义上（应该就是指非康德意义上）的先验：证明某类不同于&感觉&的实体的存在。

Besides, after this system has been brought into operation for 1 year, there was abundant ecology in the surroundings, and any ecological imbalance such as ecological singularization or species advantages has not happened due to the set-up of this system.

统合分析，本系统未来并没有铺设不透水布之必要性，且本系统运作ㄧ年之后，周遭生态丰富，并不会因为设置本系统，而造成生态单一化、某些物种优势化生态失衡的情况发生，植种结构有34科87种；两栖类有3科4种；爬虫类有6科10种；鱼类有4科8种，且有多种鸟类接近或进入本系统中，并且本系统排放水因溶氧较进流时增加，可改善河川水体因河川溶氧降低、水量减少而造成河中鱼类暴毙的窘境。

And their syntheses in the nearly past 20 years were illustrated.

According to analyzing for the existing three- impulse control system, using the theory of information cluster and syzygium, and according to the characteristic of neural network kind fuses, we have established a theoretical model of syzygium and clustering control of three-impulse water level movement course.

本项研究就是根据锅炉水位控制综合、复杂、困难的特点，并通过对现有的锅炉三冲量水位控制系统进行分析，采用信息聚类融合理论，依照神经网络自身的特点，建立了一个锅炉三冲量水位变动过程的聚类控制的理论模型。

The thesis is made up of four part:Part one: introduction and base theories of susytainable development.Part two: contrast analysis on the target system of sustainable development, the design of targer system in LangFang city.Part three: The positive illustrative of sustainable development in LangFang: The evaluation indicator system and evaluation model of He Bei province sustainable development was put forward applying the systems analysis method. This paper analyzes the sustainable development status of 11 cites via SAS and improved AHP as well as illuminates the key principles of the Principal Component Analysis and AHP. Based on the result, this paper ranges 11 cites by the level of the sustainable development status, and then, appraises the sustainable development of cites synthetically in LangFang.Part four: sustainable development strategy of LangFang city.
