The products were identified by IR,NMR,MS and elemental analysis. In our method,K.OH was used in place of NaOH to synthesize benzyl ester of 3,5-dimethyl-4-hydroxybenzoic acid,2',6'-dimethyl-4'-(n-succinimidyloxycarbonyl) phenyl-acridinium-9-carboxylate was purified on a silica gel column with chloroform/ethylacetate(4:l,v/v) as eluent and further purified by triturating with hexane/acetone(2:l,v/v).The luminescence produced by DMAE-NHS is a flash light with maximumemission at 0.4s and decay half-time of 0.9s. The luminescence intensity is 6.11x10 cps/mol,which is affected by the composition of trigger and surfactant.

DMAE·NHS的合成是本论文的关键和难点，我们对文献方法进行改进：文献方法用氢氧化钠与3，5-二甲基-4-羟基苯甲酸反应制得3，5-甲基-4-羟基苯甲酸钠，再用3，5-二甲基-4-羟基苯甲酸钠与苄氯作用制备3，5-二甲基-4-羟基苯甲酸苄酯，我们用氢氧化钾代替氢氧化钠，使合成取得成功；在合成2'，6'-二甲基-4'-苯基-吖啶-9-甲酸酯时，文献方法对粗产品进行两次硅胶柱层析纯化，第一次柱层析用氯仿/乙酸乙酯(4：1，Ⅴ：Ⅴ)作溶剂和淋洗剂，第二次柱层析用己烷/丙酮(2：1，Ⅴ：Ⅴ)作溶剂和淋洗剂，按照文献方法得到的不是所需要的化合物，我们只进行第一次柱层析纯化，然后用己烷/丙酮(2：1，Ⅴ：Ⅴ)进行研磨，过滤，洗涤，除去溶于己烷/丙酮(2：1，Ⅴ：Ⅴ)的部分，得到所需要的产品。

According to the change of the kinds of elements content in slag, F in slag volatilizes in the form of KF and NaF, KF volatilizes much more easily than NaF, KF plays a leading role in the F volatilization, theoretical analysis shows that the saturation vapour pressure of KF in the test slag is 31. 4 times of NaF; when F content is far more than K, KF volatilization is first order grade reaction, it is dominated by K content, the apparent activate energy is 275. 30KJ/mol.

4依据对含氟熔渣中高温条件下（1450℃、1505℃）的各种元素含量的变化情况，发现氟在熔渣中是以碱金属氟化物挥发，并且，KF比NaF具有更好的挥发性，在氟的挥发中占主导地位，理论研究也证明，在1505℃试验组成的熔渣中，KF的饱和蒸气压是NaF的31.4倍；在含氟量远大于钾含量的情况下，KF挥发为一级反应，受钾浓度控制，其表观活化能为275.30KJ／mol。

乙酸苯酯(分子式C8H8O2)是重要的药物中间体，它可以转化得到邻羟基苯乙酮和对羟基苯乙酮的混合物，可用于治疗急慢性黄疸型肝炎、胆囊炎等疾病，其中邻羟基苯乙酮是合成抗心律失常药盐酸普罗帕酮的重要中间体。

It was found that the content of γ-amino butyric acid in brown rice reached the maximum value after soaking for 4 hours at the ratio of brown rice and sodium glutamate 1 200 g/mol, and under the soaking!conditions of pH 5~6, Ca~ 2+ Conceutritio...

In the measurement of the hydroxyproline in the collagen,the traditional acid hydrolysis method is that under 110 ℃ the animal organism is hydrolyzed with 6 mol/L HCl,for 24 h.

在胶原的羟脯氨酸测定中，传统的酸法水解是在110℃下使用6 mol/L的HCl消解24 h，其操作步骤繁琐且所花时间较长。

It is suggested that TDS can be used as a new method for the analysis of pedogenesis and climatic change.

总之，热处理过程中磁化率的变化能非常灵敏地反映磁性矿物的转化情况，而且，这种转化往往与样品所经历的土壤化作用强度密切相关，因此，TDS可做为分析成土作用强度和古气候变化的一种新方法。

Therefore, in this chapter, I will research into the conflict and contradiction of the paternity. Also, in this novel, the father's behavior of "He who loves well chastises well." is quite suspicious, one of the reasons is that the father thought his son belonged to him. And then, this thesis quoted Lacan's theory to touch upon that someone who has accepted the concept of patriarchal society, he will be influenced for his whole life. That also reveals that human being has no choice sometimes in this society.

因此本章会先就父子关系的冲突与矛盾做深入的探讨，小说中的父亲似有对儿子爱之深责之切的行为，其原因可能在於父亲将儿子视为所有物所致；其次，论文将引用拉冈相关理论，讨论在父权社会中，不论身分为何，只要是已受父权社会观念根深蒂固影响的人物，终生都将受其所苦，此也揭示出人生存於社会上的无奈。
