Two experiments were conducted to investigate the effects of diatary supplementation with sunflower oil plus calcium pyruvate on rumen fermentation and fatty acids of cis9, trans11-CLA and trans vaccenic acid (trans 11-C18, TVA) in ruminal digesta.

为研究添加葵花油和丙酮酸钙对山羊瘤胃消化代谢、瘤胃内容物中共轭亚油酸(c9， t11-CLA)含量及组织内源合成CLA前体反式油酸积累的影响，进行了体外与体内两组试验。

Polyvinylpyrrolidone/vanadyl glycolate VO(OCH2-CH2O core-shell microspheres were assembled by soft-templating method using vanadyl acetylacetone VO(acac2 as raw materials.

以自制的二乙酰丙酮氧钒VO(aca2为原料，通过软模板法组装出聚乙烯吡咯烷酮/钒前驱体核壳结构的复合微球。

The vasodilating mechanism of AE from CM ma he related to promoting the release of NO from endothelium of blood vessel and synthesis of NOS and NOS in aortic tissue.

桑白皮丙酮提取物的舒张血管作用机制可能与血管释放NO和促进cNOS、NOS合成有关。

Results AE from CM had vasodilating effect on the contracti on of mesentery blood capillary in guinea pigs and the contraction of rat thoracic aortic ring induced by l0μmol/L phenylephrine, even under the condition of pre-treating with glibenclamide (1μmol/L) or propranolol (3μmol/L). When the endothelium of the rat thoracic aortic ring was removed, AE from CM had not vasodilating effect hut constrictive effect. AE from CM could also increase the contents of NO, NOS and cNOS in the aortic tissue and had no obvious effect on the NO content in plasma and iNOS in aortic tissue of rats.

结果 桑白皮丙酮提取物有抑制去甲肾上腺素收缩豚鼠肠系膜微血管的作用，抑制苯肾上腺素(10μmol/L)收缩离体大鼠胸主动脉环的作用，预加优降糖或普蔡洛尔(3μmol／L)后仍然有松弛作用；大鼠胸主动脉环去内皮后药物无松弛作用，反而起收缩作用；显著升高血管的NO和NOS、cNOS含量，对大鼠血浆的NO和血管iNOS的含量影响不大。

HCHO drops spirally along with the time,and but with transitory rises in summer,acetone and acetaldehyde decreases wavily.

空气中甲醛随使用时间的延长呈现伴夏季升高的螺旋样下降趋势；丙酮和乙醛呈波浪样下降；VOCs的污染水平使用初期最高，但下降较快，1个月后至初始的1/10～1/20。

The blend treated mechanically was extracted by xylon and aceton one by one.

经过力化学处理过的混合物用二甲苯和丙酮逐一浸取。

In anaerobic conditions,yest and other organisms carry out alcoholic fermentation that converts pyruvate to acetaldehyde and then to ethanol, regenerating NAD+ that allows glycolysis to continue.

在缺氧条件下，酵母和其他组织进行醇的发酵，使丙酮酸转化为乙全然后为乙醇，再生NAD+，使糖酵解继续进行。

When they were diluted to 1%, the eye irritation of acet, alcohol and DMSO were little, while methanol had eye irritation still.

当稀释为1%后，丙酮、乙醇、二甲基亚砜无眼刺激性，但甲醇刺激性仍然较高。

The main components of the waste gas from the industry of plastic tan are benzene,toluene,dimethylbenzene,xylene and acet.

塑料制革业生产过程中产生的主要污染物是苯、甲苯、二甲苯和丙酮等，由于强度不大，在一般大气扩散条件下可以满足环境质量标准的要求，但仍会对环境产生一定影响，必须引起重视。

Stuffing is innocuity for God's image.pull on rubber glove please when using .if stuffing is left at skin,clean it with alcohol, acet., benzene etc

e。 填料对皮肤无刺激、无毒，对人体无害。但是，施工操作最好戴橡皮手套。如有填料粘留在皮肤上，可用酒精、丙酮、汽油等溶剂，十分容易的清除干净。

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。
