fish freshness meaning in English
鱼类鲜度
Examples
- Therefore it is urgent to research and develop a rapid , easy and non - destructive way to detect fish freshness by using gas sensor
半导体金属氧化物wo3用作电导型气敏材料已经为人们所熟悉,但用它来检测三甲胺( tma )气体制作鱼鲜度传感器的研究还处于起步阶段。 - Nowadays , at home and abroad , one of the most widely used methods is judging fish freshness by detecting the compound of decomposed product caused by adenosine triphophate in the fish ’ s tissue in a chemical way . but this method has much shortcoming like manipulating complicatedly , costing highly , consuming much effort and time . and it needs to damage fish sample , so it is difficult to generalize the method in fact
最常用的鱼鲜度检测方法是通过化学手段测量鱼体内三磷酸腺苷分解产物的成分来判断鲜度,其操作复杂、成本高、费时费力,且需要破坏鱼体样本,难以推广使用,因此迫切需要利用气敏传感器开发一种无损、快速、方便的鱼鲜度检测方法。 - It is well known that wo3 is a conductance - type semiconductor gas sensing material , but the research on fish freshness detector with wo3 - based gas sensor to trimethylamine is still at a beginning stage . in this project , the wo3 - based gas sensors to trimethylamine are made , and their gas sensing performance are researched , especially at low temperature , the results are as follows : 1 . the nano - sized wo3 powder is prepared by sol - gel method of sodium tungstate and hydrochloric acid , and its microstructure is analyzed by using xrd , sem and tem , for material ’ s microstructure is closely related to gas sensing performance
本课题制备了wo3材料,并以它为基材,制作了三甲胺气敏传感器,研究了其对三甲胺的气敏性能,尤其是低工作温度下的气敏性能,得到结果如下: 1 、本课题以钨酸钠和浓盐酸为反应物,用溶胶凝胶法制备了纳米wo3材料,并采用x射线衍射分析仪( xrd ) ,扫描电镜( sem ) ,透射电镜( tem )对该材料进行结构分析和形貌观察,研究发现材料的微观结构与气敏性能紧密相关。
