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
如何看待北京十三号线西二旗站地铁里的拳击赛？
大家好，我是罡风，今天我决定入驻知乎了，这是我在知乎的第一篇文章，希望我的文章能帮助更多普通人在面对一些极端情况时更好的保护自己。
本篇将教会大家在搭乘地铁、公交、火车等公共交通工具时，与他人发生了矛盾，遇到了一个无礼的家伙向你抡起了拳头，本篇会教你如何在乘警出现之前，打烂他的脸。
以地铁为例，中国地铁车厢的长度一般在25米内，宽2.5-3.0米不等，这就严重限制了打斗的空间，再加上椅子、扶手等内置设施的阻隔，想来上一场酣畅淋漓的恶战，看来是有些束手束脚。

It’s been 10 years since the movie adaptation of Big Hero 6 was released and 3 years since the TV spinoff ended. And I’m still annoyed that Disney didn’t take the opportunity to turn the show into Bill Nye the Science Guy with crimefighting: highlighting a real scientific concept in each episode and using it to stop the villain of the hour.

felt crazy relaxed and easy breathing. i did notice at around the mile and a half point (11:30 in?) my HR jumped. around this time i also noticed i had to switch to more mouth breathing because my nose was running. going to try to take note of this because if it is a fault on the watch side then i can not consider it a reliable measurement.
