冬至(Winter Solstice),是中国农历 中一个非常重要的节气,也是中华民族的一个传统节日,冬至俗称“冬节”、“长至节”、“亚岁”等,早在二千五百多年前的春秋时代,中国就已经用土圭观测太阳,测定出了冬至,它是二十四节气中最早制订出的一个,时间在每年的阳历12月21日至23日之间,这一天是北半球全年中白天最短、夜晚最长的一天;中国北方大部分地区在这一天还有吃饺子、南方吃汤圆的习俗,谚语:冬至到,吃水饺,还有关于该节气的诗词和影视作品。

根据周朝的记载,民间有利用冬至日至郊外祭祀天的活动,又因为周历的正月为夏历的十一月,因此,在周代的正月等于我们现在的十一月,所以拜岁和贺冬并没有分别,一直到汉武帝采用夏历后,才把正月和冬至分开,因此,也可以说:过“冬节”是自汉代以后才有,盛于唐宋,相沿至今。

冬至

唐、宋时期,冬至是祭天祭祀祖的日子,皇帝在这天要到郊外举行祭天大典,百姓在这一天要向父母尊长祭拜,现在仍有一些地方在冬至这天过节庆贺。

就因历法的不同,使得民间一直传承著周历历法,认为冬至过后就是另一年的开始(才有吃圆仔后就 多了一岁的说法)这也是冬至为何在民间会那么受重视,但是这样的错误传承,使得民间的观念与目前择日学上,所用的夏历历法有了很大的出入,这样的错误观念 应该矫正,把正确的历法传承才对。

PM是英文particulate matter(颗粒物)的首字母缩写。准确的PM2.5定义要在“直径”之前加一个修饰语“空气动力学”,这可不是故作高深。空气中的颗粒物并非是规则的球形,那怎么定义又怎么测量其直径呢?在实际操作中,如果颗粒物在通过检测仪器时所表现出的空气动力学特征与直径小于或等于2.5微米且密度为1克/立方厘米的球形颗粒一致,那就称其为PM2.5。这样的定义也就决定了在测定PM2.5时,需要利用空气动力学原理把PM2.5与更大的颗粒物分开,而不是用孔径为2.5微米的滤膜来分离。

知道了PM2.5的定义,就很容易得出PM10的定义了——将定义中的2.5换成10即可,PM10也被称为可吸入颗粒物。在PM10中,直径在2.5至10微米之间的颗粒物被称为粗颗粒物,与细颗粒物相对。

pm2.5

也就几天,直接飙升到排行榜第一位。。。哎。啥时候能好点

We've tripled bandwidth allowances at VPS.NET

 

Over the past few weeks we have been making a number of upgrades to the infrastructure that powers our cloud servers. Our latest upgrade has taken place today. Every standard node now comes with3 terabytes of bandwidth, effectively tripling bandwidth allowances at VPS.NET.

We’ve been able to do this through a series of network upgrades that we’ve completed in our datacenters which have dramatically increased our network performance and stability. Additionally, we’ve worked tirelessly with our bandwidth providers to ensure minimal latency & optimal routing. As part of this, we’re proud to announce that we’ve added multiple new bandwidth providers to our mix, including AboveNet, nLayer & Zayo.
