【The K 聊汽车安全（2）】汽车工程是如何进行人体伤害评价的？
汽车碰撞安全设计主要考量的，就是在发生碰撞事故时保护乘员和行人等道路弱势群体，减轻事故给乘员和道路弱势群体造成的伤害。
我们在上一讲中已经对全球主要的汽车安全法规和C-NCAP类第三方评价规程进行了详细的解读。
The K：【The K 聊汽车安全（1）】带你认识全球汽车碰撞安全法规
不管是什么安全法规，判断安全性能好坏的标准，都是以人为本，从人可能受到伤害的严重程度出发，综合评价，从而给出车辆的安全等级。
那么，如何对人体所受伤害的严重程度进行评价呢？
总体而言，人体伤害一般分为两个评价维度：第一，人体各部位所能承受的机械载荷限值。第二，根据伤害风险曲线来判断载荷作用下发生伤害的可能性。
一般来说，我们按不同的区域将人体的损伤度量区域分为头部、颈部、胸部、下肢。
接下来我将分部位给大家介绍评价捋一捋，针对人体不同区域，汽车工程是如何对所受伤害的严重程度 … ⌘ Read more

骑行时需要怎么保持正确的呼吸方法？
我在21年底，去上海做fitting follow的时候，和我的fitter：Johnny Chong —— Specialized中国的Master Fitter ，讨论过关于呼吸法的问题和一些基础原理，从中也获益良多，可以和大家分享一下。
如果你不想了解原理，只要在保存气道畅通的情况下了解两点，并且在日常生活中就不断练习到成为习惯：
1.尽量用鼻呼吸，少用或不用口呼吸；
2.学习完全呼吸法，多深呼吸少浅呼吸；
——————————————————————————————————————
第三次强调， 自行车运动的本质是有氧耐力和无氧耐力，所以我们如何能够获取并利用更多的氧气来和自身产生氧化反应驱动自身，尽量减少进入无氧区间的可能性，同时在必须要进入无氧区间时能维持更久输出更多，就成了整个自行车运动除技巧外的全部，所有的训练也都是围绕着这个目标来制定的。

燃炉面具：弯曲角围绕的那副石面具，据说是来自角人们的传说故事中，所提及的 火焰恶神。
熔炉鳞/羽/瘤护符：“此为生命初始之时的熔炉残存的痕迹，也是 局部性的隔代遗传，在古代具有神圣意义。然而在文明发展后，被视为玷污的象征。”
熔炉百相之角：此为黄金树的初始生命力量，熔炉百相之一。在过去，生命是相互混合，不分彼此。
熔炉薄翼护符：角人们认为熔炉相当神圣——因为在那 历经淬炼的进化尽头，就是他们身上的混生角。
各种角饰品+2:对角人们而言， 角是神圣的象征，也因此证明他们是受选的子民。 其中不停萌发新芽的混生角，则被视为灵力之首的象征。

为什么燃油车很少刹车失灵，而新能源汽车刹车失灵概率高，这是什么原因？
我觉得横向对比吧，把相同的因素尽可能剔除掉，仅保留明显差异的变量。
因此关于驾驶辅助啊，自动驾驶这些我们先不考虑它。
我觉得其实最主要的因素可以归结到两点：
- 同级别的电动车，在重量上显著高于燃油i车（又在动力上很容易达到高速）
- 电动车为了操作便利性引入的“单踏板模式”对于用户的习惯培养
我们先说第一点： 重量！
将车辆制动下来，在燃油车时代和电动车时代有点小区别：
- 燃油车的制动力，通常包括：发动机制动（来自于泵气损失）+制动系统制动力
- 电动车的制动力，来自于：能量回收力矩+制动系统制动力
而需要制动的动能呢，本身和什么形式无关。只与车辆的速度和质量有关。根据高中物理中包含的动能公式，制动总能量为

名画pk决赛：当名画《清明上河图》PK《千里江山图》，你觉得哪幅画在你心中更胜一筹？
太巧了，这正是个把月前我在高中美术鉴赏课中抛给学生的一个辨析问题。学生们回答的很不错。我就直接搬运一下他们的答案吧。先说结果。52人的班级多过半数（有超过30人）投给了《清明上河图》，我也是。学生比较成熟的代表观点如下：
选《清明上河图》方：
1 题材稀缺，古代绘画中描绘祖国大好河山的作品比比皆是，关注民生反映现世生活的比较稀有，表现内容看似平常，但人间烟火的平凡朴实更能打动人心，相较古人胸中丘壑的理想，不仅具有丰富的艺术价值，历史价值更胜一筹。
2 画工超牛，几百个人物生动形象，细致描画，三教九流，神态各异。细节丰富耐看，画面节奏感强，突出高潮，故事性、趣味性，引人入胜。
3 画面有深刻内涵，通过特有的风俗画的艺术形式即实现了当时隐喻曲谏的政治目的，如今又是考证宋代社会经济，民生阶层，城市治理，对外贸易交流，国防政策及实效的第一手资料，比《东京梦华录》的记载更详实生动细致。
