21. | Character: Precipitated silicon dioxide( white carbon black) used for rudder products can improve intensitity of rubber tearing, toughness and wear-resisting. |
| 产品特性:用于橡胶制品中,可提高胶料的拉伸强度,弹性及撕裂强度,并可减少橡胶的用量,降低生产成本。颗粒状,不规则块状白炭黑分散性高,混炼吃料快,改变了粉状白炭黑粉尘飞扬的现象。 |

22. | Some important factors such as the mole ratio of glycerol to Lauricacid, synthesis temperature and catalyst were studied and the optimum condition of synthesis was determined as follows: synthesis temperature was at 180CC, mole ratio was 2:1, and 0.2% P-Toluene Sulphonic acid was served as catalyst. |
| 考察了影响产物产率及纯度的因素,确定了反应的最佳条件是:反应温度180℃,甘油与月桂酸的摩尔比2:1,催化剂对甲基苯磺酸的用量0.2%。 |

23. | The effects of the ratio of solvents, the quantity of emulsifying agents and stable agent, the amount of modification monomer and functional monomers and initiator on the properties were studied. |
| 研究了溶剂比、化剂与稳定剂用量、性单体及功能单体的用量、发剂及交联剂用量等因素对粘接性能的影响。 |

24. | Similarly, provision of a deficient nutrient like sulphur may raise the marginal products of nitrogen, phosphate, and potash, thus requiring increased levels of these nutrients. |
| 同样,增施其他肥料如硫肥,有可能会提高氮、磷和钾肥的边际产量,因此需要进一步增加这几种肥料的用量。 |

25. | " When they fed Chao poison, they indicated the amount by saying to each other:" The price of cotton is ten cents" or" The price of wheat is thirty cents," depending on how much arsenic was in the cakes that day. |
| ”他们给赵树理吃毒药时,也用黑话说毒药的用量,如说“棉价一毛”或“麦价三毛”之类的话,表示每天在烙饼中的砒霜用量。 |

26. | It contained a month's supply of dry milk for his two young children, and a potential lifesaving medicine to help cure them from Chikungunya fever, a disease that causes very high fevers and is especially dangerous for the young. |
| 该包裹装了他两位小孩一整月的奶粉的用量,并且包括有救命药品以帮助他们免受曲弓热的感染,该曲弓热对年青人会导致发高烧并且有生命危险。 |

27. | Their efforts include not only finding methods to raise the activity of the catalyst so less can be used for the same power output but also determining how to form a stable catalyst structure that does not degrade over time and avoiding side reactions that contaminate the membrane. |
| 他们不仅致力于寻觅提升触媒活性的方法,好以较少的用量达到相同的输出动力,还尝试做出不会经时耗损,又能避免次反应污染隔膜的安定触媒结构。 |

28. | To decrease the amount of bleeding,the operators can anesthetize the nasal mucosa with 1% ephedrine and tetracaine,then add 1% tetracaine to 30ml adrenalin. |
| 为减少术中出血 ,可将副肾素的用量增至5mg ,术前先用 1%麻黄素丁卡因棉片麻醉鼻腔黏膜 ,然后将 1%丁卡因 30ml加入副肾素 5mg浸注棉片麻醉黏膜 ,促使黏膜内血管收缩减少循环血量。 |
