| 1. | Tertiary treatment comprises a series of physicochemical steps . 三级处理包括一系列物理化学处理步骤。 |
| 2. | Large stack deposits are controlled by deeply dipping faults tertiary age . 巨大的堆型矿体受第三纪倾陡断层控制。 |
| 3. | Isomeric alcohols, tertiary amines are less water soluble than their isomeric primary and secondary amines . 异构的醇,叔胺的水溶性比其异构的伯胺和仲胺小。 |
| 4. | Isomeric alcohols, tertiary amines are less water soluble than their isomeric primary and secondary amines . 异构的醇、叔胺的水溶性也比其异构的伯胺和仲胺小。 |
| 5. | Isomeric alcohols, tertiary amines are less water soluble than their isomeric primary and secondary amines . 异构的醇、叔胺的水溶性也比其异构的伯胺和伸胺小。 |
| 6. | Thus varying the nature of r from primary to secondary to tertiary alkyl results in increasing yields of the hydroxy ethers . 当R按伯、仲、叔烷的顺序递变,则所得羟基醚的产率就随之而增高。 |
| 7. | Many drugs and pesticides contain tertiary amino groups and could, therefore, be expected to undergo nitrosation in the body . 有很多的药物和农药含有叔胺基团,因此有可能在体内发生亚硝基化。 |
| 8. | Tertiary amines, although basic, fail to yield amides, presumably because they cannot lose a proton, (to stabilize the product)after attaching themselves to carbon or to sulfur . 叔胺虽然呈碱性,但不能产生酰胺,这大概是因为当它们连在碳或硫上之后,无法失去一个质子(以稳定产物)的缘故。 |

| 10. | Food additive - tertiary butyl - 4 - hydroxyl anisole 食品添加剂叔丁基- 4 -羟基茴香醚 |
