Acid in high-acid foods may react with the iron of the can to release hydrogen and generate a hydrogen swell. Hydrogen sulfide production by Desulfo. tomaculum can cause sulfur stinkers

在高酸的食品中的酸可以和罐头中的铁发生反应生成氢气而产生膨胀，由脱硫肠状菌产生的氢人氢能导致含硫磺的恶臭物质的形成。

Effects of different pyrolytic temperatures on the formation of aromatic substances were investigated by pyrolysis chro-matography-mass chromatography when β-carotene was pyrolysed at high temperature under nitrogen protection.

利用裂解色谱-质谱联用仪对β-胡萝卜素在不同温度下进行裂解时所生成的香味物质进行了研究。

Methods: Phloroglucinol react with formaldehyde to come into being a yellowish-red dyestuff, the color of dyestuff changes with concentration of formaldehyde.

间苯三酚在强碱性条件下，与甲醛反应，生成橙红色物质，随甲醛浓度增加颜色加深。

A significant proportion of these acids come from sulphur in the fuel which reacts during the combustion process and builds sulphur ic acid, a very corrosive and acidic component.

它们中有很大一部分来自于燃油中所含有的硫，这些硫在燃烧时会生成硫酸，而硫酸是一种具有很强的腐蚀性和酸性的物质。

Glucose A monosaccharide (C6H12O6) occurring widely in nature as a storage compound: it occurs as glucose units in sucrose (which is hydrolyzed to glucose and fructose) and GLYCOGEN, as well as in STARCH and CELLULOSE.

葡萄糖：是普遍存在于自然界的一种单糖（ C6H12O6），可以作为储藏物质。葡萄糖是蔗糖（可水解生成葡萄糖和果糖）和糖原的基本单位，同时也存在于淀粉和纤维素中。

The humic acid was used as the precursors of trihalomethanes, the overall reaction order is second-order.

以腐殖酸为三卤甲烷形成的前驱物质，确定THM 生成的反应级数为二级。

Oil is from the age of the ancient organic materials (mainly single-celled plants, such as blue - green seaweed; single-cell animals, such as foraminifera) deposition, after a long-term physical and chemical changes in production.

石油是由古地质年代有机物质（主要是单细胞植物，如蓝-绿海藻类；单细胞动物，如有孔虫类）沉积后，经过长期物理、化学变化而生成。

Antiparticles are created elsewhere in the universe where there are high-energy particle collisions, such as in the center of our galaxy, but none have been detected that are residual from the Big Bang, as most normal matter is [1] ( http://science.nasa.gov/headlines/y2000/ast29may_1m.htm ).

科学家在1995年成功生产了氢的反原子，以及反氘核核子，由一个反质子和一个反中子生成，仅仅还不能是更为复杂的反物质。

And between the temperature and the amount of time that it takes to cook, these carcinogens form.

这些致癌物质与加热的温度和烹调的时间有着密切关系，温度越高，生成的致癌物就越多。

The thoracic duct ligation has blocked chylomicrons to blood, diminished the formation of LDL, after all and made the absorption and metabolism of lipid abnormal.

在食管癌根治术中结扎胸导管，阻断了乳糜微粒入血，导致LDL生成减少，对脂类的吸收代谢有不良影响，因此主张脂肪以外的营养物质可经肠内供给，而脂肪营养则从静脉供给，从而促进病人的康复。

I can not make it blossom and suits me

我不能让树为我开花

When temperatures are above approximately 80 °C discolouration of the raceways or rolling elements is a frequent feature.

当温度高于 80 °C 左右时，滚道或滚动元件褪色是很常见的特征。
