As the representatives of salt - free organic reductants , hydrazine derivatives possess such advantages as strong reductivity and high selectivity . the kinetics of the reaction of np ( vi ) , pu ( iv ) reduction by hydrazine derivatives have been studied deeply since 1980s . the results show that it ' s potential for applying hydrazine derivatives as salt - free reductants in purex process in the near future 以肼类衍生物为代表的有机无盐还原剂，具有还原能力强、选择性高的特点。自上世纪八十年代以来，对于肼类衍生物还原np ( ) 、 pu ( )的动力学已进行了较为深入的研究，并获得了一系列重要的参数。
To add flavour , use herbs or spices such as ginger , spring onion , garlic or dried tangerine peel , etc . , ( western herbs like parsley , coriander , pepper , etc . , ) to season foods instead of preserved or pickled food and seasonings such as salted fish , salted eggs , miso , oyster sauce , etc . , ( western food or seasonings like sausages , stock cubes , salt at table , etc . , ) 处理方法：要增加食物的味道，可选用天然调味料如姜、 ? 、蒜、果皮等，以代替腌制食物或调味料，例如咸鱼、咸蛋、面豉、蚝油等。
