hydrogenating

hydrogenate的音标为["haɪdrədʒɪdeɪt]，基本翻译为“氢化；使成氢化合物；使含氢”，速记技巧为“氢化=氢+化=hyd+gen+ate”。

Hydrogenating这个词源自拉丁语，意为“氢化”。它的变化形式包括氢化程度的加深，如深度氢化(deep hydrogenation)、部分氢化(partial hydrogenation)等。相关单词包括：

1. Hydrogenation of fats and oils（油脂氢化）：油脂氢化是食品工业中常见的过程，但过度氢化会导致脂肪和胆固醇含量增加，对健康不利。

2. Hydrogen-free gas（无氢气体）：无氢气体是一种纯度极高的气体，不含任何氢元素。它通常用于电子工业和半导体制造等领域。

3. Hydrogen-rich water（富氢水）：富氢水是一种近年来兴起的水饮，据说具有抗氧化、抗衰老等功效。

4. Hydrogenation of polymers（聚合物氢化）：聚合物氢化是一种化学反应过程，可以改变聚合物的分子结构和性能。

5. Hydrogen-assisted hydrogenation（氢辅助氢化）：这种过程是在氢化过程中引入氢气，以提高反应速率和产品纯度。

6. Hydrogenation of proteins（蛋白质氢化）：蛋白质氢化是一种化学改性过程，可以改善蛋白质的溶解性和稳定性。

7. Hydrogenated fats and oils（氢化脂肪和油）：这是一种被广泛使用的食品添加剂，但过量摄入可能对健康产生负面影响。

8. Hydrogen-free gas carrier（无氢气体载体）：无氢气体载体是指运输无氢气体的设备或系统。

9. Hydrogenated vegetable oil（氢化植物油）：这是一种常见的食品添加剂，常用于烘焙和烹饪中。然而，过量摄入可能对健康产生负面影响。

10. Hydrogenated rubber（氢化橡胶）：氢化橡胶是一种经过化学改性的橡胶材料，具有更好的耐热性和耐老化性。

常用短语：

1. hydrogenate the fats and oils

2. hydrogenation process

3. hydrogen-donating agent

4. hydrogen-rich gas

5. hydrogenation reaction

6. partially hydrogenated fats

7. fully hydrogenated fats

例句：

1. To prevent heart disease, we should avoid fully hydrogenated fats in our diet.

2. The hydrogenation process is used to increase the shelf life of some foods.

3. The hydrogen-donating agent in this product is safe and effective.

4. The hydrogen-rich gas is used to generate fuel cells.

5. The hydrogenation reaction is a complex chemical process.

6. The partially hydrogenated fats in this recipe are suitable for those who want to reduce their intake of saturated fats.

英文小作文：

Hydrogenation is a process that adds hydrogen atoms to unsaturated fats, which makes them solid at room temperature and increases their shelf life. However, hydrogenation also increases the risk of heart disease, so it is important to choose foods that are not fully or partially hydrogenated and to avoid hydrogenated fats in our diet. On the other hand, hydrogenation is also used in the production of fuel cells, which convert hydrogen into electricity without producing any emissions that are harmful to the environment. Therefore, hydrogenation has both positive and negative aspects, and it is necessary to carefully consider its use in different contexts.
