In order to research the relations of carbon sources to structure of PHAs, six kinds of PHAs sample were synthesized by activated sludge with six different carbon sources respectively in the aerobic-anaerobic-anoxic process. Their structures were determined by 〓HNMR、〓CNMR and GC-MS. When the carbon source was acetate, the unit composition of PHAs was 93. 91mol％ 3-hydroxybutanoic acid and 6. 09mol％ 3-hydroxypentanoic acid ; When the carbon source was propionate, the unit composition of PHAs was 28. 66mol％ HB, 63. 13mol％HV, 2. 55mol％ 2-methy-3-hydroxy-butanoic acid (2MHB) and 5. 66mol％ 2-methyl-3-hydroxypentanoic acid (2MHV); When the carbon source was 80％ butyrate and 20％ 1, 4-butanediol, the unit composition of PHAs was 65. 03mol％ HB, 28. 06mol％HV, 1. 91mol％2MHB, 2. 69mol％ 2MHV, 0.73mol％ 4-hydroxy butanoic acid (4HB), 0.78mol％ 4-methyl-3-hydroxy-pentanoic acid (4MHV), 0.80mol％ 3-hydroxyhexanoic acid ; When the carbon source was 20％ butyrate and 80％ 1, 4-butanediol, the unit composition of PHAs was 61. 39mol％ HB, 23. 01mol％HV, 4. 58mol％2MHB, 5. 97mol％ 2MHV, 0.91mol％ 4HB, 2. 37mol％ 4MHV, 1. 77mol％ HHx; When the carbon source was 60％ pentanoate and 40％glucose, the unit composition of PHAs was 41. 24mol％ HB, 58. 76mol％HV; When the carbon source was 60％ benzoate and 40％ glucose, the unit composition of PHAs was 65. 48mol％ HB and 34. 52mol％ HV.

为了研究不同碳源与产物PHAs结构的关系，采用好氧-厌氧-缺氧模式利用6种不同碳源培养活性污泥得到6种不同的PHAs样品，通过〓HNMR、〓CNMR和GC-MS谱图确定了这6种PHAs的单体成分和比例：以乙酸钠培养活性污泥得到的PHAs的单体组成是93.91mol％3-羟基丁酸和6.09mol％3-羟基戊酸；以丙酸钠培养活性污泥得到的PHAs的单体组成除28.66mol％HB、63.13mol％HV外，另外还有2.55mol％3-羟基2-甲基丁酸（2MHB）和5.66mol％3-羟基2-甲基戊酸（2MHV）；以80％丁酸钠和20％1，4-丁二醇混合溶液培养活性污泥得到的PHAs含有七种单体组成：65.03mol％HB，28.06mol％HV，1.91mol％2MHB，2.69mol％2MHV，0.73mol％4-HB（4-羟基丁酸），0.78mol％4MHV（3-羟基-4-甲基戊酸），0.80％HHx（3-羟基己酸）；以20％丁酸钠和80％1，4-丁二醇培养活性污泥所得到的PHAs含有与3#样品相同的七种单体，只是比例不同，分别是61.39mol％，23.01mol％，4.58mol％，5.97mol％，0.91mol％，2.37mol％，1.77mol％；以60％戊酸钠和40％葡萄糖培养活性污泥所得到的PHAs由HB和HV组成，比例是41.24 mol％∶58.76 mol％；以60％苯甲酸钠和40％葡萄糖培养活性污泥所得到的PHAs也由HB和HV组成，比例是65.48 mol％∶34.52 mol％。

In clinical. acetylcholinesterase inhibitors reduce the breakdown of synaptic acetylcholine, have been modestly effective in improving the cognitive deficits of Alzheimer's disease.The goal of this work is to determine enzyme kinetics and mechanisms of acetylcholinesterase and butyrlcholinesterase inhibition by five cardiovascular drugs, lovastatin, simvastatin, amlodipine besylate, nifedipine, and hydralazine hydrochloride, and two benzodiazepines, diazepam and chlordiazepoxide hydrochloride. All drugs in this study are reversible mixed-type inhibitors of acetylcholinesterase and butyrylcholinesterase. The pKi values for acetylcholinesterase and butyrylcholinesterase inhibition by the cardiovascular drugs are linearly correlated with the molecular weights of the drugs with the slopes of 0.005 and 0.0021, respectively. Therefore, van der Waals' interactions between acetylcholinesterase and the cardiovascular drugs are stronger than those between butyrylcholinesterase and the drugs. This is probably due to a smaller active site gorge and a more significant peripheral anionic substrate binding site of acetylcholinesterase than those of butyrylcholinesterase.

本研究之目的系决定乙醯胆碱酯酵素和丁醯胆碱酯酵素被五种心脏血管药物lovastatin， simvastatin， amlodipine besylate， nifedipine、hydralazine hydrochloride和两种benzodiazepines：diazepam和Chlordiazepoxide hydrochloride的抑制作用之动力学及机转，这些药物都是乙醯胆碱酯酵素和丁醯胆碱酯酵素的可逆性、混合型之抑制剂，实验结果显示，五种心血管药物对於乙醯胆碱酯酵素及丁醯胆碱酯酵素抑制之pKi值和药物之分子量呈直线之关系，斜率分别为0.005及0.0021因此丁醯胆碱酯酵素，与心血管药物间之凡德瓦作用（van der Waals' ）比乙醯胆碱酯酵素与心血管药物间者弱，这可能原因是丁醯胆碱酯酵素之活性区域比乙醯胆碱酯酵素之活性区域更宽广，但丁醯胆碱酯酵素之周边阴离子区域不及乙醯胆碱酯酵素之周边阴离子区域者明显重要，由於五种心血管药物对於乙醯胆碱酯酵素和丁醯胆碱酯酵素抑制之pKi值存在著线性关系表示此种抑制作用系经过共同之反应机理。

In this paper the study on optimizing the esterification of cellulose and some character of CAB(the degree of substitution of cellulose, solubility, the thermal properties and molecular weight) was discussed. The mechanism of the esterification of cellulose in butyric acid/ acetic acid/ butyric anhydride which comprises the creation of the acetic butyric anhydride, acetyl cation and butyryl cation was investigated by the study of the effect of the content of the organic acid and anhydride on the degree of acetyl and butyryl substitution of cellulose.

认为：其一，建国后党的文艺意识形态改变了丁玲将《文艺报》办成文学刊物的初衷，而使之成为代表党的意志指导全国文艺运动与创作、参与并监控思想文化斗争的党的机关刊物；其二，尽管丁玲本人畏于文艺/政治斗争，但五十年代初丁玲及《文艺报》组织批判萧也牧的方式是建国初期文艺批评所谓群众批评模式的典范案例，这表现出丁玲对体制的努力适应与迎合；其三，&作家&/&主编&/&党的文化官员&/&党的文学教育者&的多重文化身份和文化认同使丁玲建国初期的&言&与&行&呈现出分裂、矛盾状态，这说明丁玲又不能被意识形态彻底整合。
