The results showed that : 1 During nonbreeding season, the giant panda′s ovary was still rich with large and small follicular oocytes, and the large follicular oocytes could be matured in vitro; 2 The mean diameter of the oocytes was (141±6.7)μm and lots of cortical granules contained in the cytoplasm of oo...

结果表明∶（1）在非繁殖季节，大熊猫卵巢中小腔及大腔卵泡卵母细胞仍较丰富，其大腔卵泡卵母细胞可在体外培养成熟；（2）大熊猫的卵母细胞平均直径为（141±6.7）μm ，其胞质富含卵黄颗粒；（3）自配 PandaI I号获能液（含丙酮酸钠、肾上腺素等）可使大熊猫精子有效获能；（4）大熊猫卵母细胞体外受精后，经培养可观察到第2 极体，有的受精卵开始发生卵裂。

As for the mesh screen type, its volume multiplied by 100% its porosity was the desirable filling amount. Having considered the forgoing findings, the researchers add up the amounts of the above two types as the filling amount of the composite micro structure, with the filling fluid being acetone. In fabricating the heat spreader, a copper pipe is added to serve the filling purpose. What is more, because the manufacturing process is not carried out in a totally clean environment, there is some noncondensible gas left, which will have a negative effect on the performance of the heat spreader. Consequently, the copper pipe has to be reserved so that the exhaust gases can be evacuated after the filling is done.

Kempers 文中可知，沟槽结构之填充量以微结构体积之80%为最佳，网格结构则是以网格体积乘上孔隙率(porosity，φ)之100%为最佳，故本研究便以两者之加总做为复合式微结构之填充量，填充液为丙酮；在均温基板之制造程序中，会加装一铜管做充填之用，且而由于制造过程并非于一完全干净之环境下完成，故板内会有一些不利于均温基板作用之非凝结性气体noncondensible gas (NCG残留，因此铜管需保留一定的长度，以方便充填完成后将废气排出之用。

Octylene was synthesized via tetramerization of ethylene at the presence of a catalyst system consisted of chromium acaet as primary catalyst, methylaluminoxane as cocatalyst, bis amine as ligand under high pressure. The effects of different PNP ligands on catalyst activity and selectivity to 1-octene were investigated.

在乙酰丙酮铬、甲基铝氧烷、配体三元催化体系中，以乙烯为原料在高压下齐聚生成1-辛烯，主要考察N原子上取代基不同的PNP配体对催化剂活性及1-辛烯选择性的影响。

In this paper,the monomers including St and BA with strong waterproof property were employed to modify the traditional PVAc emulsion,and meanwhile draw into DAAM functional monomer in the copolymer system,will prepare out cross linking copolymer emulsion for ADH to improve the waterproof,oilproof and dry/wet mechanical property of fuel oil filter paper.

采用具有较强抗水性的苯乙烯、丙烯酸丁酯等单体对传统聚醋酸乙烯酯乳液进行共聚改性，并在共聚体系中引入双丙酮丙烯酰胺功能单体，制备出可通过外加己二酸二酰肼交联的外交联醋丙共聚乳液，以期提高燃油滤纸的耐水、耐油性和干湿态的力学性能。

Albendazole and oxfendazole both inhibited the pathways of anaerobic glycolysis, partial inversed tricarboxylic acid cycle of Taenia Solium oncosphere, immature and mature cysticerci in vitro and immature and mature cysticerci in vivo in certain degree. They enhanced decomposing in fat, amino acid, and xanthine metabolism. On the other hand, absorption of glucose was hindered.

阿苯哒唑和奥芬哒唑对体外培养猪六钩蚴，未成熟期和成熟期猪囊尾蚴，以及体内发育未成熟期和成熟期猪囊尾蚴的糖无氧分解途径，丙酮酸羧化支路与逆向三羧酸循环途径均有一定程度抑制作用，代偿性促进糖异生及蛋白质，脂类和核酸分解途径，葡萄糖吸收受阻。

The gene for pyruvate kinase,which is involved in glycolysis and catalyze the biochemical reaction from phosphoenolpyruvate to pyruvate,was screened,cloned and sequenced from non photosynthetic Oomycetes,Achlya bisexualis cDNA library.

从真菌藻状菌纲Achlyabisexualis的cDNA文库中克隆了糖酵解途径的最后一种酶—丙酮酸激酶的基因，获得这个基因的完整阅读框架，并且对这个基因的全序列进行了测定。

In the process of wet dentin bonding, acetone-based adhesives have higher microtensile strength than alcohol-water-based adhesives. Although two types of bonding system have full resin penetration in the bonding interface, the latter possess distinct overwet phenomenon.

在牙本质湿粘接过程中，以丙酮为溶剂的粘接系统的微拉伸强度，高于以酒精和水为溶剂的粘接系统；虽然二者的粘接界面中都可以观察到粘接剂在牙本质表面充分的渗透，但后者有着更为明显的过度润湿现象。

Results: Comparing with movement fatigue group, blood glucose contents were significantly increased but oxypropionic acid and urea nitrogen contents were significantly increased; testosterone and T/C were significantly advanced, myocardium SOD activity was significantly increased, while MDA was significantly decreased in cluytyl alcohol preparation group.

结果：和运动疲劳组相比，补充二十八烷醇制剂组大鼠血糖显著升高，血乳酸、血尿素氮显著降低；T、T/C比值显著增高，心肌SOD活性显著增强，MDA含量显著降低，且效果优于丙酮酸－肌酸组。
