The conclusion indicated that pyruvate supplement could accelerate the speed of body energy metabolism and slower weight and body fat gain during exercises. Due to the influences of pyruvate supplement on the levels of enemies and hormones to adjust body lipometabolism during exercises, body blood lipid and glucose levels decreased, and the process of fat metabolism came under.

丙酮酸补充可在一定程度上减慢运动机体体重和体脂的增长速度，加快运动机体能量代谢速度；并通过影响运动机体脂肪代谢相关调控酶和激素水平，使其血脂和血糖水平下降，从而影响其脂肪代谢过程。

If 0.01 M sodium malonate is added to actively respiring mitochondria that are using pyruvate as fuel source, respiration soon stops and a metabolic intermediate accumulates.

如果0.01M丙二酸钠加入到以丙酮酸为能源并正在进行活跃呼吸作用的线粒体中，呼吸作用很快停止，代谢中间产物累积下来。

So the catalysts for producing methylglyoxal from 1,2-propane glycol were studied in this thesis.

因此本文对丙二醇氧化制备丙酮醛的催化剂进行了研究。

The technology of producing methylglyoxal in our country was developed in recent years, but its capacity is small, and the catalyst is very expensive too.

国内丙酮醛的生产起步晚，规模较小，并且所需催化剂比较昂贵。

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。

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。

Successful separation of Cd-pheophytin a, Cd-pheophytin b, chlorophyll a, chlorophyll b, pheophytin a and pheophytin b in 14min was firstly accomplished by reversed-phase HPLC at a flow rate of 0.8ml/min, with the mobile phase of methanol: acetone (80: 20, v/v).

首次以甲醇：丙酮＝80：20为流动相，流速为0.8ml/min，在C〓柱（5μm，4.0×250mm）上，14min内成功实现了镉叶绿素a和镉叶绿素b配合物与叶绿素a，b和脱镁叶绿素a，b的高效液相色谱分离。

The synthetic conditions of 4,4 dimethyl 3 oxopentanenitrile prepared sequentially from acetone through pinacol , pinacol one and α chloro pinacol one were investigated.

对以丙酮为原料、先依次制得片呐醇、片呐酮、α氯代片呐酮、最后由α氯代片呐酮与NaCN反应制得 4，4 二甲基 3 氧戊腈最后两步的反应条件进行了研究。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.

提出了用测地线方程、曲面上两点间短程线来计算膜结构曲面测地线的方法，同时，采用测地线间垂线的中点连线和用无约束极值法进行空间条状曲面近似展开的分析。
