Now I'm a fan of 银刀哥. The particles in the air might also be anchor points for viruses. Wherever the air quality is better, there are fewer particles, and less virus to be spread around. kamchee 发表于 2/13/2020 4:39:53 PM
回复 106楼silverblade的帖子 英雄所见略同啊 Researchers say a certain spectrum of ultraviolet light -- called far-UVC -- easily kills airborne flu viruses while posing no risk to people. It could offer a new, inexpensive way to eliminate airborne flu viruses in indoor public spaces such as hospitals, doctors' offices, schools, airports and aircraft, said the team from Columbia University Medical Center in New York City. Can UV Light Be Used to Kill Airborne Flu Virus? https://www.webmd.com/cold-and-flu/news/20180212/can-uv-light-be-used-to-kill-airborne-flu-virus-#1 Far-UVC light: A new tool to control the spread of airborne-mediated microbial diseases https://www.nature.com/articles/s41598-018-21058-w/
你只是提出，event A and event B are correlated; but there is no clear evidence that event A and event B are causally related; with A being the leading event that happens, B happens as a result of A.

“On the Boeing 777, re-circulation fans are used to augment the airflow in the cabin. It provides a mixture of about 50 percent outside air and 50 percent re-circulated air; a balance has been achieved to maintain a high level of cabin air quality. For your information, in-flight cabin air is of a better quality than air in the average office building or shopping complexes and is changed completely in a very short period of time (between 2 to 3 minutes).
The Boeing 777 cabin design provides a ventilation rate of 13 to 20 cubic feet per minute of air per passenger. The 50 % cabin air is highly filtered re-circulated air where viruses and bacteria are removed. The filtration systems used are High Efficiency Particulate Air Filters (HEPA-type), similar to that used in hospital operating rooms.”
"The 787 has even better air quality due to an innovative purification method known as gaseous filtration. Research has shown that contaminants cause many of the symptoms that often are associated with low humidity. Air purification removes those gaseous contaminants and reduces symptoms such as throat irritation."
再增加历史回溯解释：新型冠状病毒，其原始宿主是蝙蝠，中间宿主是穿山甲。这两个动物有什么共同点？这两种动物都喜欢钻在洞里，在阴暗潮湿的地方生活。这说明新型冠状病毒很可能也喜欢阴暗潮湿的地方。反过来，明亮的地方，干燥的地方，这个病毒不喜欢。
机舱根本挡不住宇宙射线。前面有网友说了，曾经在飞机上亲测过辐射强度，暴高。
风花雪月只是我的爱好，工程技术可是我的专业。
握手。我早就知道不能娶空姐。空姐天天在天上飞，接受的辐射量大，影响到基因的稳定性，对生孩子可能不利
能不能展示一下你的高人一等的科学素养？
这个例子太棒了，我要将你的回帖搬到顶楼去。
谢谢你的回帖，很受鼓舞。我在华人上蹦下跳了半年，终于也有一个粉丝了。
Silver做工程技术，这个我不怀疑。可是，我怀疑你没有学过概率论啊.

都跟他说过五遍了，中文也说过英文也说过，中英文也说过
哦，这样啊，我们可能需要用写诗的方式。
Silver如果不听，那，我们把这个楼给歪了。。。。今天天气如何？
任何完整的理论，都需要一个过程来建立，不是一开始就是什么都是对的。比如量子力学，不停地修改提炼，花了几十年才搞掂。我主楼里的东西，是一个唯象的经验的东西，属于不完备理论。需要补充实验来证实。具体做什么实验，我在文中也提了。不完备理论也是非常重要的，因为指明了方向。
我也觉得楼主说的有一定道理，提供了一个新的思考方向， 就是不知道有没有人从这方面研究
re，要是那只猫，绝对会说中国崩溃，川总英明，绝对不会对抗疫抱着如此积极乐观的态度的
你坐飞机从不说话的？
飞机人不怎么动，不怎么接触，不怎么说话的。所以没有传染。说在飞机上跟陌生人聊天的，极少。而且病人本来就不舒服了，怎么聊。。
我来试试：
长途飞机，很多波音777，787 (747 基本淘汰了)， A380/A350：

空客的系统没去查。
