vacuum preservation

Combined with vacuum packaging and pasteurization, NaL and Nisin were used for sauced duck preservation.

利用乳酸钠和乳酸链球菌素在肉制品保鲜中的协同作用，将乳酸钠和乳酸链球菌素结合真空包装、低温杀菌技术应用于酱鸭保鲜。

⑷ There is more effect for packing material in preservation. General PE is not fit for vacuum packing and gas flushing.

⑷包装袋材料对保鲜效果影响很大，普通的PE薄膜不适合于抽真空或充气等处理。

The Al-Cu eutectic brazing metal is made to braze pure aluminium substrate in vacuum. The diffusion phenomenon of Cu in pure aluminum bar under different brazing temperature and heat preservation time is investigated by means of SEM and EDS.

制备Al-Cu共晶合金钎料，用SEM和EDS研究不同钎焊温度和保温时间条件下，纯铝棒料基体对接真空钎焊接头Cu元素的扩散行为。

The utility model can keep constant temperature, and have a longer heat preservation time than common vacuum cup, thermos cup and the like.

且能恒温并能比普通的保温杯真空杯之类保温更长的时间。
