为什么我的猫看我吃螺蛳粉会以为我在吃“屎”,但我吃进去却不觉得?
因为引起螺蛳粉的臭味物质和便便的臭味物质并不是同一个。而猫对诸如螺蛳粉、榴莲等有特殊气味的食物出于嫌弃,可能会有“埋屎”行为,并不一定是认为你在吃屎。

便便的臭味是由粪臭素(3-甲基吲哚)引起的,存在于哺乳动物的粪便中,为色氨酸在消化系统中的产物。

而螺蛳粉的臭味是其中的配料酸笋发出的,近两年对广西酸笋挥发性成分的研究中发现:

1、酸笋的主要气味成分大致有10多种,主要气味特征是酸味、酸臭味和刺激性气味以及发酵香味;

2、对甲苯酚和乙酸是主要的气味成分。

3、酸笋主要香气属性酸臭味主要与对甲苯酚(窖泥臭)、苯乙醇的浓度呈较好的相关性。酸味及刺激性气味与对乙基愈创木酚、3-辛醇具有较好的相关性。而发酵香味与3-辛醇、壬醛、反-2- … ⌘ Read more

如果让你来改进一座「筒子楼」,你会怎么设计?

引子

筒子楼也算是一个时代的印记了。在还不富裕的年代,以低成本、模块化方式大批量快速建造的筒子楼,对解决温饱问题中的「温」做出了巨大的贡献。就筒子楼住宅而言,它们的普及度在各个城市强弱不一,一般而言,北方城市、国有/集体经济发达的城市,筒子楼的存在感更强一些。但是另一种筒子楼,我相信无论是70后80后90后,都真真切切地接触过、并且住过不止一年,那就是: 学生宿舍

筒子楼的特点

筒子楼的特点都围绕着经济性。在百废待兴、并不富裕的年代,筒子楼的这些特点都是优点,比如:

灯塔之下,科学璀璨

1、 为什么要做《某科学的超级实验室》

《某科学的超级实验室》是一个“探室”主题的系列纪录片,其实在灯塔计划之前,我就已经尝试做过两期内容,

在我看来,这个项目想要展现两个方面,一个是科学家的精神面貌,另一个是我国的大科学装置。为什么要做这个主题呢?因为我们自己作为一个科研人员,对于科研人员是一种什么样的状态,什么样的表现,有着比较深入的理解。但是感觉大众对于科学家这个群体还是比较陌生的,而且会受影视作品的影响,对科学家有一些刻板印象。我希望想通过一些视频去把它展现给大众,让大家真正的去了解科学家到底是什么样子的,科研工作到底是什么样子的。
