In this thermodynamic study, the minimum requirements in molar fraction of the solvents (x3) on the azeotropic feed plate are: 0.20 for N,N-dimethylformamide, 0.36 for 2-ethoxyethanol, 0.40 for 1-pentanol and 0.66 for butyl propionate,.

在这个热力学研究中，共沸混合物喂料盘上各溶剂摩尔分数最小值(x3)分别是：N，N-二甲基甲酰胺：0.20；2-乙氧基乙醇：0.36；1-戊醇：0.40；丙酸丁酯：0.66。

For long-term treatments, the rat administered daily by gavages for six weeks, the results of OGTT showed that guava fruit water or alcohol extracts could reduce the plasma glucose level in the diabetic Wistar rats, however there was on significant difference in insulin level among all tested groups. The results of carbohydrate metabolism showed diabetic Wistar rats administered with 200 or 400 mg/kg BW of guava fruit water or alcohol extracts could decrease more than 15% glucose-6-phosphatase and fructose-1,6-bisphosphatase activities, and it also increase more than 12% glucose-6-phosphate dehydrogenase activities to reduce inhibitory hexokinase from reducing glucose-6-phosphate level.

在醣类代谢方面，实验结果发现糖尿病鼠灌食番石榴果实水及乙醇萃取物六周后，肝脏醣质新生作用中丙酮酸合成肝醣之关键酵素glucose-6-phosphatase及fructose-1，6-bisphosphatase的酵素活性会降低15%以上；另一方面肝脏glucose-6-phosphate dehydrogenase酵素活性则明显增加12%以上，并造成glucose-6-phosphate浓度减少，进而降低其对hexokinase的抑制(因为hexokinase受其代谢产物G-6-P的浓抑制)，因此加速肝脏葡萄糖的糖解作用。

Hunter L, a, and b color value of starch/dHG films did not show significant difference with potassium sorbate, however, with extractive thyme, the hunter L, a, and b color value of starch/dHG films showed significant difference and light green-yellow.

淀粉/dHG可食膜的抗张强度及抗张模量一般而言随著添加抗菌剂浓度的增加而减少。添加己二烯酸钾对淀粉/dHG可食膜的L、a、b值没有显著的影响，但添加百里香乙醇粗萃物则有显著的影响。

With regard to the common type in, you typically add phosphoric acid, ammonium nitrate and ammonium dihydrogen phosphate, ammonium dichromate, citric acid and gum Arabic and other chemical components; alcohol fountain solution also includes ethanol or isopropanol.

差于普通型的润版液，凡是补充磷酸、硝酸铵、磷酸二氢铵、轻铬酸铵、柠檬酸和阿拉伯胶等化学组不合；酒精润版液还参加乙醇或异丙醇。

The extract was precipitated at isoelectric points of rapeseed protein (pH 4.0), and then decolorized by 70% ethanol to obtain the rapeseed protein with light-gray.

经等电点沉淀、70%乙醇脱色及冷冻干燥后，产品呈浅灰色，菜籽蛋白质得率为9.3%，单宁脱除率为56.65%，植酸脱除率为62.77%，硫甙脱除率达93.66%。

So it can keep invariable bulk phase transition within a wild neutralization range;AB-I and AB-II show the similar phenomenon in bulk phase transition,but not very similar in methanol and ethanol.Perhaps this is because of competition between hydrophile and lyophobic.

AB-I样品分子链上的磺酸基团(-SO3-)完全电离，与树脂网络外部溶液浓度差始终较为恒定，所以能在较宽的中和度范围内(40%～80%)保持较为恒定的相变体积；AB-I和AB-II在电解质溶液中表现出类似的体积相变规律，而在甲醇、乙醇中表现出不尽相同的相变规律，这可能是由于AB-II中存在亲水力和疏水力相互竞争作用的结果。

The synthetic liquid fuel is compounded with basic material including methanol and ethanol as well as additives including stearic acid, peroxide of oil and grease, potassium chlorate, zinc peroxide, methyl benzene, methane, cyclohexane, etc.

本发明是一种合成液体燃料及其生产方法，这种燃料由基料甲醇、乙醇和硬脂酸、过氧油脂、氯酸钾、过氧化锌、甲苯、甲烷、环已烷等添加剂经混合加热反应配制而成。

N-doped TiO2 photocatalysts were fabricated by mixing tetrabutyl titanate with urea in ethanol and water by solgel method, and immobilized to granular activated carbon by coating.

以尿素为N源、以钛酸四丁酯和乙醇为原料，采用溶胶－凝胶法制备N掺杂TiO2，并用浸渍法将TiO2负载于粒状活性炭上，通过烧结制成N-TiO2/AC光催化剂。

The two pyruvates are then converted by the yeast into carbon dioxide(CO2) and ethanol (CH3CH2OH, which is the alcohol in beer). The overall reaction

两个丙酮酸盐被酵母放换成为二氧化碳(CO2)和乙醇(CH3CH2OH，也便是在啤酒中的酒精)。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。
