Principle: Traditional tobacco is smoked by ignition. The temperature of tobacco when burning reaches 800 degrees. Nicotine, carbon monoxide, tar, etc. will be produced in the process of tobacco burning. At the same time, tobacco itself also has fragrance released. Smokers are mainly satisfied by smoking nicotine and tobacco fragrance. There are more than 2,000 kinds of harmful ingredients produced by smoking, The main components that cause harm to human health come from tar produced in the combustion process, However, the working temperature of the heating non-burning electronic cigarette is about 300. Not more than 300 degrees, Tar is mainly produced at over 400 degrees, In other words, Heating does not burn electronic cigarettes. Due to the relationship between temperature, A small amount of tar is produced, which can be ignored. Moreover, the temperature at which heating does not burn is only about 300 degrees, so there is no combustion, no open flame and no soot. However, the aroma and smell of tobacco are still released, and smokers can also obtain nicotine, so that smokers can also obtain the feeling of smoking real cigarettes.奥斯卡金像奖获奖导演戴维斯·古根海姆（《难以忽视的真相》《他叫我马拉拉》）带来新作《走进比尔：解码比尔·盖茨》。这部全新的三集纪录片探索了著名技术先驱、商业领袖和慈善家比尔·盖茨的思想和抱负。在辞去微软首席执行官职务之后，盖茨将时间和出色才智投入到解决一些世界上最持久的问题上，由此便开始了现代史上最伟大的职业生涯第二幕。该剧集深入并真实地描述了比尔·盖茨在人生历程中经历的成功和挫折，以前所未有的深度让我们了解了比尔·盖茨，他的乐观、好奇心和热情曾激发他对微软的初始愿景，现在也激励他为世界上一些最复杂的问题寻求解决方案。《走进比尔》记录了这些努力与个人时刻，采访了比尔和梅琳达·盖茨，以及他们的朋友、家人、慈善事业和商业上的合作伙伴，塑造了一个富于创新的真实的人物形象，在改变世界之后，他可能还将改变人们看待世界的方式。赵举，一名普通的社会底层从业员，坚持自己的一套，声称有自己的原则，可谓有棱有角，不懂变通！而生活也就此埋下了梁子，不光是爱情，职场与友情，他处理的都不好。当又一度的爱情再一次的席卷而来，他将如何应对······萧何续道：尹旭此举大大jī怒了项羽，据说他麾下苏角所部三万人被勒令驻留新安附近，不得回秦国故地。2019年，日本迎来了令和时代，而医疗界陷入大混乱——权威世代与次世代的竞争、与电脑、AI的共存等诸多问题乘着时代的波涛扑天盖地而来。就在这时，东帝大学医院出现了前所未有的赤字。外号“秃鹰”的投资家尼古拉斯·丹下来处在破产边缘的“白色巨塔”。根据全世界屈指可数的企业再生专家丹下提出的再生计划，东帝大学医院走上了经营重建的道路。但是，另一方面，迫于“医疗合理化”的压力，医院也面临着裁员和削减成本的现实，本是拯救生命的医疗前战，却变成了“生意优先”，越发成为政治与权力争夺的战场。这时，大门未知子被丹下叫回东帝大学医院。在新的权力争夺白势化的“白色巨塔”，她展开了孤高的挑战。章邯这话有斥责的意思，也有开脱的意味。
