lazy and pride
common people fail as lazy, success is achieved by external factor, family support, industry developement, other people help.but we can only control internal factor:talent,education,hardwork,persist. many people make up their mind to change themself and few can do it. because they can not do it continuously, goal is never esay and difficulty always exist, in this time, we must keep doing it and solve the problem one by one, insist can make up the talent.If you want to have good speaking english, spend 1 hour everyday to practice it.If you want to have healthy body, spend half day everyweek to do exercise.Keep simple goal and do it every day, don't be disturbed by other entertainment.talent people fail as pride, arrogant make us underestimate the difficult and overestimate the talent, they don't want do detail work and overlook many reality problem. there are huge gab between real situation and their theory.then they will not control the result and just give high pressure to other people. other people won't tell your the truth and just keep distance from you.

Gas industry
Gas is consumable chemical material,the average gas consume is maybe 100$ per person in US, while chinese is 40$. So, there are high potential for gas usage amount in china when the industry upgrade. Gas is a good and stable business, it connect to many other industry,even though one industry will decline,but the other industry blooming will eliminate this effect.Different gas have different product way.The most common gas, nitrogen,oxygen and argon are separated from air, hydrogen can product by methanol cracking,CO2 is purified from duty gas,CH4 is purfied from natural gas.SF6 is react from S and F2, while F2 is product from rock called yingshi.In this situation, the process consist of production, purify, filling, storage, delivery. One facility just product one or two kind of gas.It's difficult to hava complete gas supply chain.There are lots of sale company to get these resource together.But in gas industry, air separation is most imporatant.The biggest company start their business from it. air separation generate the liquide nitrogen,liquide oxygen and liquide argon, which account for majority of gas comsume.but we won't build a air separation facility to sale liquide or gas, the investment is too high.The normal situation is building it for other company, such petrochemical, coal or metal smelt which use great amount of liquide.And sale the rest of liquid to other smaller user through liquide truck.For the smaller user, they will use package gas cylinder. There are lots of filling station for cylinder because the distance advantage. The package gas transport fee is high and one station just serve customer within 70km.But package gas have different feature for different customer demand, we can simple classify it to industrial gas, high purify carrier gas, calibration gas, chemical gas and electrical gas.Industrial gas consume amount is large and majority use in cutting and welding, different welding technology use different kind of gas, it have not high requirement for gas purity. High purify gas mainly use in high tech equipment for protection and purge, high demand for mositure and oxygen.Calibration gas is used for analysis equipment calibration,make sure the result is accurate.Different chemical gas have various use purpose, co2 can use for cell cultivation, mathane or c3h8 can use in stove equipment test to make sure burn sufficient. SF6 is used in many high voltage equipment for electric protection.The last one, is most complicated and rely on foreign country.The electrical gas mainly used in semi-conduct process, from keshi, CVD, fengzhuang and so on, like N2O,NH3,HCl,HBR,CF4,SF6,C4F8,F2,SiH4,PH3,BCl3, most of these is flammable and toxic gas, extremely dangerous and high quality demand.For semi-conduct production, gas quality will effect the batch product qulity, the loss will reach billion level, so process control is important, every process must have sop, training and record, any change must be permitted and consider the effect.In this area, international company have reputation and success experience, account for majority of the market.But more and more molecular can be produced in domestic, localization is important trend, but it's hard to replace foreign company, which has accumulated much engineering experience and tech advantage.The production element include labor, land, capital, tech and data. china path is exchange market to tech and talent labor.At the same time, support some local company development.

大宋提刑官-为什么官员会贪污
{tabs}{tabs-pane label="中文"}每个人都会面临两个选择,职责或者私欲;每个人都会在中间找一个位置,多数人都是灰色的多数人喜欢的还是欲望、色欲、暴食、嫉妒、贪婪、傲慢、懒惰、愤怒。这是一种生物本能为人民服务是本分,为自己服务是私欲。这种选择只是一念之差,越是聪明的人,越是懂得利用规则,将私欲隐藏在职责之中,让人难以察觉。另外,国家虽然需要法治,但毕竟是人治的。法律也靠人来取证、审查和定罪。但现实往往是难以监督的,所以需要人做决定的地方就是权力,规则和界限越模糊,检察的难度越大,权利就越大,有权力的地方就会有腐败。权力可以决定事情的结果。在大多数情况下,腐败会使结果符合少数人的利益而损害多数人的利益。从整个社会来看,如果20%的人占有80%的财富(猜想),也可以说他们占有80%的权利,所以权利集中在少数人手中,利益分配定下来后基本很难改变,很多事情的结果本来就只符合少数人的利益,比如世袭贵族、国企职位传给下一代、高考分省录取等。腐败会加剧这种不公平。如果不加以控制,社会发展的趋势将是不平等和两级分化。中国两千多年的朝代更替都是在重复这个故事。所以,没有目标或者外界的压力和竞争的威胁,是一件很悲哀的事情。大家只想着怎么过得舒服,就没有改变的动力和勇气,也就没有创新和发展。以下总结了腐败或挪用公款的原因:1.满足私欲,想要更好的物质生活,喜欢美女,孝敬父母,孩子的教育,爱好等等。2.受上级、同事、朋友的影响,其他人都是这样做的。3.家人、同学、朋友的请托,不是为了自己,是讲义气,但发现即使我做了,别人也不会注意到,越演越烈4.升职,取悦上级需要政治资金容易腐败的地方:1.采购权,花钱的地方就可以捞钱,所以很多国企即使是亏损的,每年也有很多项目,花的钱也很多2.执法司法权,公安检察院,包庇儿子犯法,电视上都是这么演的3.选人用人权利4、国有企业改制与国有资产流失5.城市土地利用、土地性质变更6.审批权限、行政审批、新设企业项目审批、危险化学品经营许可证换证审批7.资金划拨、国家自然科学基金拨款、私人挪用资金、占用公共资产、设立小金库{/tabs-pane}{tabs-pane label="English"}Everyone face the choice between duty and desire.Majority like the desire eventually:sex,lazy,greedy,angry,jealous,arrogant,gluttony. It's creature nature. server{/tabs-pane}{/tabs}

数字化转型的意义
数字化,工业4.0,工业孪生,智能制造这些词都指向未来的方向其实制造业发展的方向一直没有变,以最低的成本制造出符合需要的产品;核心就是成本最低,但成本包括多个环节:研发,制造,运输,销售,库存,市场营销等,我们比较容易控制单一环节的成本,软件也是单一环节进行开发,造成不同环节软件信息无法传递,无法进行全局优化。同时智能是迅速适应变化,能把正确的信息,在正确的时间,用正确的方式传递给正确的人,以此为依据帮助做出正确的决策。我把它定义为数据的自动流动。达摩研究院的安筱鹏说:数字化转型最本质的定义是,在数据叫算法定义的世界中,以数据的自动流动化解复杂系统的不确定性,如何对外部的环境变化做出响应,最终的目的在于提高资源配置的效率;智能制造更强调设备的智能和自动,逐步取代人的工作;同时数字化转型的核心矛盾是企业全局优化的需求和碎片化供给之间的矛盾。意义:1.全局优化,将企业内部孤立的系统数据打通,将企业之间的数据打通2.数据的自动流动,将数据在合适的时间传递给合适的人,提高对外界变化的适应能力,提高柔性和定制化生产的能力;低代码自己定义流程3.IOT,系统连接底层执行单元,获取更多的信息和进行控制4.知识经验性数据的积累和使用,如标气能不能做,能做什么范围5.AI,对于过程不好定义的函数,使用机器学习从经验中学习来解决其他:6.流程控制,所有订单都录入系统,保证下单了就执行,执行完了收到钱7.纸质变成电子的,查询传递更方便,审批简单8.对于部分重复性工作计算机辅助执行,生成订单,对账单,开发票等9.记录可以重复使用的数据,客户信息,产品信息10.权限控制11.数字孪生,建立模型进行模拟开发和辅助决策12.区块链,分布式的信任中心引用: 数字化转型的本质-阿里安筱鹏

Identification-when we will make mistake
There is no problem if only one road.we will make mistake if there are two road to choose, and if the choice is similar and more, we will make mistake easier.Moreover, we always make mistake when we didn't realize we can choose. If there a small way beside the road and we can't find it easily as a barrier, we will miss it. If someone ask me for a help and i won't do it right now, i will forget it easily.For these situation,identification is really important, make different choice different with various method, there should be a board to guide the small way, we call it visualization;we should record some task in notebook in case we forget, we call it process management; we use different valve for different gas in case of wrong connection, we call it physical separation. We put different class in different area, we call it space separation.The world tend to be mess, we call it entropy increase. we need to reverse it,Goal of management is to make it ordered, to classificate, to sort,to conclude constant,to find variable item.For example, customer need a adapter for H2 bundle to G5/8,i just think 21.8L to G5/8,and i don't realize there are two kind of valve for H2 bundle, and i choose the usual way automatic in brain without hesitation. It's small mistake but maybe lead to big accident. So we must keep cautious how many way we have.

大秦帝国裂变-治国之难,在于锄奸,不在扬善
穷则思变,居安思危规则和立场,法治和人治,欲望,对权利的迷恋,对利益的攫取才是对规则最大的威胁,最后规则和法律变成平民的枷锁,上层的特权元帅和君主考虑的是资源的分配,这个事应该不应该做,怎么做,谁去做,给他多少资源,需要他做到什么程度,他能做到什么程度,告诉他要做到什么程度,结果和过程好不好监督和衡量,做好了怎么奖励背景:秦国和当时最强大的魏国连连战争,依靠着秦人的英勇勉强支撑,但是陷入了物资匮乏境地,无法支撑战争,只能割地求和。这个节点秦献公逝世,选择了沉稳二儿子秦孝公继位,同时要求大儿子宣誓支持弟弟集位。这是秦国急需改革强大,否则就会灭亡。离间六国联盟,贿赂魏国公子,延迟出兵。在危机面前大家会团结和妥协,才有改变的动力,才有商鞅变法的平台,但即使这样,还是遭到很多既得利益集团的反对和抱负。商鞅原来是魏国丞相的门人,但魏国丞相死前向魏王举荐了他,但魏王压根不在意,他已经是最强的了,没有改变的动力,手下人听话懂事才是最重要的。这是秦王发布求贤令,召集大家前往秦国发挥,到了后给大家一个题目,访谈秦国村落后给出治国良策,商鞅虽然已经名声在外,但仍然深入基层,发现问题,大家没有种田的动力,所得不归自己;参军立功没有功勋;秦人私斗严重,经常发生小规模群殴...针对这些,分阶段出台了严苛的法律,鼓励耕种,立功进爵等遭到了贵族反对,甚至鼓动太子违法,让商鞅和公子虔立下深仇(威武不能屈,太伤面子了)废除井田制度,开始了土地私有化,允许土地买卖,鼓励开垦荒地。

置之事内-政府在经济发展中的作用
政府和企业都是在配置资源,在我国政府核心职责是发展经济,最重要是招商引资,需要合理配置土地,人才,资金等资源,提供医疗教育交通等公共服务,吸引企业在当地投资,增加就业,增加税收。事权划分的因素包括提供公共服务的规模效应,信息复杂度和激励相容。如行政区域划分。外部性指事情影响区域和范围,如果是跨省的污染需要国家部门协调权利位于规则不明确的地带,所以权利和责任往往归结到人身上。人治vs法治 情vs法 过程正义vs结果正义权责利是否一致LP和MP 私募资金定增长目标,超出目标的20%给LP,和GM的OI目标一致。面板显示行业和京东方和合肥政府的故事央地关系:鞭打快马,做的越好目标越高,会隐藏一些,并通过藏富于企业外部性税收上交,不和中央分成
