中国9073养老模式中“7”的尴尬和“90”的梦想
中国9073养老模式中“7”的尴尬和“90”的梦想“十一五规划”期间上海率先提出了9073的养老模式，即：90%家庭自我照顾、7%社区居家养老服务、3%机构养老。
这也是现阶段中国众多专家推崇的养老模式。
下面将介绍家庭自我照顾和社区养老的现状及问题。
“7”的尴尬在《北京市居住区公共服务设施规划设计指标》的条文说明中提到：1.6.6 由于北京已经进入老龄化社会，2000年第五次人口普查表明60岁以上老人已占全市人口的12.5%，预计到2010年老年人口将达到15%以上，2020年将达到20%以上，因此，增加并提高养老设施指标是十分必要的。
养老院从“02指标”的5万人/处调整为3-5万人/处，并提高了千人指标。
此外，增设老年活动场站、托老所等设施。
在新版的《北京市居住区公共服务设施规划设计指标》编制过程中显然已经考虑到了城市的老龄化问题，并作了针对性的调整，但这种调整的幅度是不是可以满足需求呢？通过附表，可以看到养老相关设施的设置标准：具体分析下：社区卫生服务站和社区卫生服务中心是服务于全体居民的，并非专为老人服务且规模很小。
老年活动场站是服务于区内所有老人，且由每150位老人分享20平方米，真正指向的是需要社区居家养老服务的老人。
按照指标要求，居住人口超过7000人的中大型小区里配置的每千人90平方米的托老所，显然是不足的。
“90”的梦想9073模式中所谓的90%家庭自我照顾，根据北京师范大学发布的《2014中国劳动力市场发展报告》显示，在现实生活中“舟车劳顿”已成为中国大城市人群每天都要经历的事情。
北上广深平均每天上下班往返时间均已接近或超过90分钟，交通拥堵以及郊区居住市内工作的模式都是通勤时间长的原因。
其中，北京通勤时间最长，达到97分钟。
即中午回家几无可能，且即使不考虑工作强度、不考虑加班、不考虑突发事件，所谓的“朝九晚五”也会变为“朝八晚六”，也即工作日至少十小时，家中老人没有家人陪伴。
主要城市通勤时间（单程）阿尔茨海默症，又名老年痴呆症。
老人90大寿祝寿词（共7篇）（精简版）
老人90大寿祝寿词(共7篇)老人90大寿祝寿词(共7篇)篇一：爷爷90大寿祝寿词爷爷90大寿祝寿词尊敬的各位父老乡亲、亲朋好友们，大家好！春秋迭易，岁月轮回，当辛卯新春以温暖的怀抱萦绕着我们的时候，我们欢聚一堂，为我的爷爷，我们尊敬的长辈共祝九十大寿。
我首先代表所有的晚辈、所有的来宾向爷爷送上最真诚、最温馨的祝福，祝爷爷福如东海，寿比南山，健康如意，福乐绵绵，笑口常开，益寿延年！我的爷爷生于年农历正月日。
他一生育有个儿女，他和奶奶含辛茹苦竭尽全力把个儿女培育成人。
早在年前，我的奶奶就因病去世，爷爷忍悲含泪，以宽厚慈爱的父亲胸怀，把全部的爱给了儿女们，一人顶着这沉重的一片天。
为了儿女们健康成长、成家立业，爷爷白天下地劳动，晚上回家缝缝补补，精打细算，操持家务，任劳任怨，把痛苦与困难留给自己，把快乐与方便让给儿女，使儿女们一个个成家立业，孙子们一个个长大成人。
那个年代，是多么的艰难，多么的不易，爷爷受到了许多常人没有经受过的磨难，可爷爷无怨无悔，他为儿女们的高兴而高兴，为孙子们的成绩而骄傲。
爷爷常教育子女要勤俭持家，诚实做人，实在办事，要我们好学上进，严以律己，努力工作，回报社会，报答家乡。
他常教育我们要与人为善，好事多办，心要学长，路要修宽，特别是要多帮有困难的人，办实事、做好事。
要堂堂正正做人。
他能带头维护好家庭和乡党，邻居间的团结与和睦，乐于助人，逢人笑口常开，把困难留给自己，把方便让给别人。
爷爷是位知足常乐的人，更是一个自得其乐的人，也富有幽默感。
爷爷的一言一行，为我们晚辈树立了良好的学习榜样，他是儿女们的好父亲，是儿媳们的好公公。
我很爱我的爷爷，爷爷是一位伟大的父亲，又是一位伟大的爷爷。
九十年风风雨雨，九十载生活苍桑。
岁月的泪痕爬上了爷爷的额头，将老人家的双鬓染成白霜。
爷爷阅尽人间沧桑，爷爷一生中积累的最大财富是他那勤劳正直的朴素品格，爷爷那宽厚待人的处世之道，爷爷那严爱有加的朴实家风。
这一切，伴随爷爷经历的坎坷岁月，更伴随爷爷迎来了今天晚年生活的幸福。

与90后员工相处的7个习惯
与90后员工相处的7个习惯千禧一代指的是出生于1984年至2000年的年轻人，他们在互联网的陪伴下长大，如今已是职场和消费的主力人群。
下面是小编为大家收集关于与90后员工相处的7个习惯，欢迎借鉴参考。
1.精简谈话内容与年轻员工谈事情，要好懂、好消化，冗长的对话就像一道大餐，吃不下又耗时。
精简谈话内容，其实就是省时间，人类一生中最宝贵的就是时间。
这里我要点名一下我们中国人，不是有鄙视国人的意思，中国大部分人说话喜欢兜圈子，然后讲完一大堆后问你：你明白我意思了吗?其实这是老一辈留下的“病根”，有一种古代封建社会的官僚形象。
说重点，先精简。
这不是逼着你去做，而是当下时代的发展，你必须掌握沟通要素。
练习方式：多读书看报，并且将自己阅读的信息用简单的话术表述出来，每周坚持。
注：过程中保持透明，交谈中注意坦诚。
2.需要交谈，而不是教训跟年轻员工谈事情要亲切，不要摆架子。
可能很多领导都有爱摆架子，来显示自己的位置，但是事实证明，大多数领导都是指坐在领导位置上面的人，但是他们并没有领导力，也没有人愿意搭理他们，所以为了引起下属对他的尊重，才会故意摆出架子的。
这其实是个恶性循环。
我们再来看看为什么这个问题是要交谈，而不是教训呢?从沟通的对立面来讲，交谈是处于双方思维的平稳对接，信息平衡输入和输出。
教训是什么，是上级以俯视态度看下属，下属低着头，沟通的信息无法形成最基础的平衡，所以这一块是导致信息不平等的关键。
这种情况最常见的就是，员工挨训后，要么做事紧张，要么就爱理不理，拖拉，耗时间。
注：目光保持平视，彼此相互尊重。
3.增加参与感勇于发声是千禧一代的强项，他们尤其讨厌职场上的独裁者，主管要懂得增加员工参与感，多听少说，不断询问员工的想法，才能促成有意义的对话。
这里讲的参与感不是领导的参与感，而是领导进行组织，让下属多发言，领导多听少说。
这一点和共产党的“民主集中把方向”类似，听取群众意见做决策。
注：人与人之间，要有相互认同感。

7张中国老照片：图1是90年代的网吧,图6会让你想起初恋!
如今的电脑早已普及，但很多人还是喜欢去网吧，因为只有在网吧才能找到“气氛”。
中国的第一家网吧出现在1996年，虽然电脑还是“大屁股”，也没什么游戏，软件也不多，每小时的网费还高达40块，却依旧人满为患。
看到这样的小隔间，有没有勾起你的回忆呢？
这是80年代的一桌豪华宴，每桌的费用抵得上普通人一个月的工资。
看看桌子上，8个菜一个火锅，有茅台有汽水，就算放到今天，这一桌恐怕也不便宜。
有没有懂酒的，看看那瓶茅台现在值多少钱？
刚刚看了豪华宴席，现在看看普通人的生活，注意店铺上面的字，牛肉一块八每斤，羊肉一块九毛五每斤。
8、90年代的时髦照相法，在景点不仅有人专门拍照，甚至会有人租小轿车、租背景牌，满足游客的一点小小虚荣心。
图中这种让照片看起来仙气环绕的方法，也很流行。
自行车的王国怎么少的了自行车，不得不说二八大杠的质量，真是杠杠的，完全可以满足全家人的出行需求，载客量堪比小轿车，只是百公里油耗需要多吃几个馒头！
每个人学生时代都有过的经历，大扫除！肯定有人特别喜欢大扫除，因为可以和暗恋的女生/男生分到一组，一起洒水，一起扫地，一起擦玻璃，这就是学生时代的单纯感情。
看到这，你有没有想起初恋，想起曾经的那个TA呀？
当年的孩子最渴望的就是一把小手枪，和一身绿军装吧。
如今的孩子是体会不到了，什么都不缺，反而没有了那种珍惜的感觉！

Vol. 7, p.368 (1990); Vol. 63, p.37 (1985).(S)-8a-METHYL-3,4,8,8a-TETRAHYDRO-1,6(2H, 7H)-NAPHTHALENEDIONE[1,6(2H, 7H)-Naphthalenedione, 3,4,8,8a-tetrahydro-8a-methyl-, (S)-]Submitted by Paul Buchschacher1, A. Fürst1, and J. Gutzwiller1.Checked by P. S. Belica, P. S. Manchand, and Gabriel Saucy.1. ProcedureCaution! Part A should be performed in a well-ventilated hood because methyl vinyl ketone is a lachrymator.A. 2-Methyl-2-(3-oxobutyl)-1,3-cyclohexanedione. A 1-L, round-bottomed flask equipped with a thermometer and a reflux condenser capped with an argon-inlet tube is charged with 126.1 g (1 mol) of 2-methyl-1,3-cyclohexanedione(Note 1) and 300 mL of distilled water. To the well-stirred suspension are added 3 mL of acetic acid, 1.1 g of hydroquinone, and 142 g (167 mL, 2 mol) of freshly distilled methyl vinyl ketone(Note 2). The reaction mixture is stirred under argon at 72–75°C for 1 hr, cooled to room temperature, treated with sodium chloride (103 g), and poured into a separatory funnel containing ethyl acetate (400 mL). The organic phase is collected and the aqueous phase is reextracted twice with ethyl acetate (150 mL each time). The combined extracts are washed with two 200-mL portions of saturated brine, dried over anhydrous magnesium sulfate, and filtered, and the filtrate is evaporated at 40°C under reduced pressure (water aspirator) on a rotary evaporator. The residue is kept under high vacuum (1.0 mm) at 40°C for 30 min to give 210.8 g of crude 2-methyl-2-(3-oxobutyl)-1,3-cyclohexanedione (1, "trione") as a pale-yellow oil, homogeneous by thin-layer chromatography (Note 3). This crude material is used in StepB.B. (S)-8a-Methyl-3,4,8,8a-tetrahydro-1,6(2H, 7H)-naphthalenedione (3-S). A 3-L, one-necked, round-bottomed flask, equipped with an argon-inlet tube and containing a magnetic stirrer, is charged with 5.75 g (0.05 mol) of finely ground L -proline (Note 4) and a solution of 210.8 g of crude trione 1 (from Step A) in 1 L of anhydrous dimethyl sulfoxide (Note 5). The mixture is stirred at room temperature (ca. 25°C) under argon for 120 hr, the magnetic bar is removed, and the solvent is removed under high vacuum (1.0 mm) at 65°C (Note 6) on a rotary evaporator to give 206.9 g of a dark reddish-violet oil. The oil is dissolved in toluene (100 mL) and is absorbed on a column (9 cm X 60 cm) of silica gel (1.5 kg, 70–230 mesh) (Note 7), which was previously packed in hexane . Elution is carried out under a slight positive pressure of argon (ca. 1 atm) (Note 8) initially with 1 L of hexane : ethyl acetate (5 : 1) and then with a 3 : 2 mixture of hexane : ethyl acetate taking 300-mL fractions. The progress of the purification is monitored by thin-layer chromatography (Note 9): no product is observed until ca. 5 L of eluant is collected. Fractions containing the product are combined, and the solvents are removed under reduced pressure (water aspirator) at 45–50°C. The residue is then kept under high vacuum (0.1 mm) at 40°C for 30 min to give 154.2 g of an orange-colored oil, which became glassy and sometimes crystalline on standing at room temperature, [α]D + 68° (toluene , c 1.5) (Note 10). This material is dissolved in 535 mL of ether and is filtered through a fluted filter paper to remove small particles. The flask is rinsed with 500 mL of ether , and this is passed through the filter paper. After cooling to 3°C, the combined filtrates are seeded with a few crystals of pure 3-S (Note 11), and the mixture is left undisturbed at −20°C for 18 hr. Most of the supernatant liquid is carefully decanted without agitation, and the crystals are collected by filtration. The flask is rinsed with cold (0°C) 50% ether in hexane and the rinse is used to wash the crystals. The crystals are dried for 16 hr under high vacuum at room temperature to yield 85.9 g of (S )-enedione (first crop), mp 49–50°C, [α]D + 96.9° (toluene , c 1.2). The combined filtrate and washings are evaporated to give 67.1 g of an orange-colored oil, which is dissolved in 604 mL of ether , cooled to 3°C, and seeded with (R,S )-enedione (Note 12). The mixture is left at −20°C for 18 hr, and the supernatant liquid is carefully decanted (no agitation). The wet crystals are then collected by filtration, washed with cold (0°C) 50% ether in hexane , and dried under reduced pressure at room temperature to give 36.3 g of racemic material (3R + 3S ). The filtrate and washing are evaporated to give 30.6 g of an oil, which is dissolved in 100 mL of ether , and filtered through a fluted filter paper. The flask is rinsed with 114 mL of ether , and filtered through the fluted filter paper, and the combined filtrates are cooled to 3°C and seeded with crystals of the pure 3-S. The mixture is left at −20°C overnight, the supernatant liquid is carefully decanted without much agitation and the wet crystals are collected by filtration and washed with cold (0°C) 50% hexane in ether . After drying 15.3 g of light amber-colored crystals (second crop), (mp 49–50°C, (or [α]D + 97.3° (toluene , c 1.0). The total yield of (S )-enedione is 101.2 g (56.8%) (Note 13).2. Notes1. 2-Methyl-1,3-cyclohexanedione 2 was obtained from Aldrich Chemical Company, Inc. or Fluka and had mp 208–210°C.2. Methyl vinyl ketone , bp 34°C/120 mm, was obtained from Aldrich Chemical Company, Inc. or Fluka.3. Thin-layer chromatography was performed on silica gel with ethyl acetate : hexane (3 : 2). Visualization of the spots was achieved by spraying the plates with 10% ceric sulfate in 10% sulfuric acid , heating the plates to ca. 120°C, and spraying again with 10% phosphomolybdic acid in isopropyl alcohol . The product has R f 0.50; 2-methyl-1,3-cyclohexanedione has R f 0.30.4. S -(−) Proline was obtained from Aldrich Chemical Company, Inc. It is also available from Ajinomoto GmbH or Degussa.5. Dimethyl sulfoxide was dried over Linde 4A molecular sieves. Anhydrous, deaerated N,N -dimethylformamide was preferred by the submitters (Note 14).36. The temperature should be kept below 70°C.7. Silica gel was purchased from EM Reagents, E. Merck, Darmstadt, Germany. The submitters preferred to do the preliminary purification by fractional vacuum distillation using a Hickman-type short-path distillation head. The main fraction distills as a light orange oil, bp 126–130°C (0.02 mm) (Note 14).8. The procedure of W. C. Still 4 is used.9. Silica gel and 60% ethyl acetate in hexane were used. The product, R f 0.40, is visible under short-wavelength UV light, whereas the starting trione, also R f 0.40, is not. Visualization is achieved as 252525described in (Note 3). 10. The material was melted at 55°C under reduced pressure (12 mm) on a rotary evaporator prior to sampling in order to measure the optical rotation on a homogeneous sample. 11. Compound 3-S was obtained from material having (or [α]D + 68° (toluene , c 1.5) that was prepared in another experiment. Thus, 28.2 g of this (S )-enedione is dissolved in 90 mL of ether and the solution is left at −20°C for 18 hr. The crystals are collected by filtration without much agitation, washed with 30 mL of cold (0°C) 50% ether in hexane , and redissolved in 117 mL of ether . The solution is left at −20°C for 18 hr, and the crystals are collected by filtration, washed with 30 mL of cold (0°C) 50% ether in hexane , and dried under reduced pressure (1.0 mm) at room temperature to give 12.0 g of (S )-enedione, mp 50°C, [α]D + 100° (benzene, c 1.5); [α]D + 97° (toluene, c 1.0). It should be possible to prepare seed crystals from a small aliquot, but this was not attempted by the checkers. 12. Racemic Wieland-Miescher ketone was obtained from Aldrich Chemical Company, Inc. or prepared according to the procedure of Ramachandran and Newman.5 13. 1H NMR studies (100 MHz, CDCl 3) using the shift reagent tris[3-(heptafluoropropylhydroxymethylene)-d -camphorato] europium(III) (purchased from Aldrich Chemical Company, Inc.) indicated that the two crops were enantiomerically pure. Under identical conditions (10 mg of reagent per 9.6 mg of substrate), absorption due to the vinyl proton at 5.86 in the racemate appeared as two peaks (1-Hz separation) of equal intensity. 14. The submitters' procedure using dimethylformamide in Step B and using distillation for isolation of the enantiomerically enriched ketone was checked by K. Job, A. K. Beck, and D. Seebach and proved equally satisfactory.3. DiscussionRacemic 8a-methyl-3,4,8,8a-tetrahydro-1,6(2H , 7H )-naphthalenedione (the Wieland-Miescher ketone)5,6 is a versatile building block for the synthesis of steroids 7 and terpenoids.8 The (S )-enantiomer, 3-S, was first obtained by microbiological means 9 and by classical resolution via a derived hemiphthalate.10 The present synthesis 3 of 3-S is based 11 12 on the asymmetric intramolecular aldolization of the prochiral triketone 1 using S -(−)-proline catalytically. The product is obtained in 56% yield (from 2) and is enantiomerically pure on the basis of optical rotation and NMR spectroscopy determined in the presence of a chiral shift reagent. Despite numerous synthetic investigations and modifications of this asymmetric Robinson annulation,13 14 15 the mechanism of enantio-differentiation is still not fully understood;16 17 18 see discussion in this volume, p. 367, relating to the asymmetric synthesis of the corresponding S -(+)-tetrahydro-7-methylindenedione .References and Notes1.

西游记85到90读后感推荐7篇
西游记85到90读后感推荐7篇读后感的写作说为了考察个人对原作的理解程度，读后感指浏览完一本书后把内心的领悟通过文字书写出来的文字报告，作者今天就为您带来了西游记85到90读后感推荐7篇，相信一定会对你有所帮助。
西游记85到90读后感篇1西游记》是一篇长篇神魔小说，前七回讲孙悟空的身世和大闹天宫的故事,第八回介绍唐僧，交代西天取经这一中心事件的由来，第十三回到第一百回是小说的主题，讲述唐僧师徒取经路上战胜无数妖魔鬼怪，历经重重磨难，终于到达西天，取回真经的故事。
小说中，孙悟空不怕困难，无所畏惧的精神值得我们学习。
独臂女孩张超凡因为天生不完整的左臂，她告诉我们:“我必须优秀，即使比别人付出多几倍的努力，也要活出个样儿来!”受父亲影响的张超凡，从小学习国画和书法，年少时便开始崭露头角，有一个星期她带回四个获奖证书，后来她考上了自己理想的大学，研习写意画鸟专业，如今的张超凡是周围人眼中的“天使”和“达人”，有人甚至称她为“东方维纳斯”。
作为一个天生残疾的女孩，她骨子里的那份坚强勇敢，不怕困难，无所畏惧远远超过了常人，一份信念，让她成为自信的标杆。
每一个人的人生经历有所不同，所以每个人看《西游记》的感悟也会不同。
如果把唐僧师徒四人取经之路比作我们的成长之路，那九九八十一难一定就是我们成长道路上遇到的挫折与磨难，而那些妖魔鬼怪就好比我们心中不好的念想，如果稍一松懈，就会误入歧途，既影响了自己，又影响了他人，而那九九八十一难的成功通过，就好比我们用自己的智慧战胜了我们成长路上的种种困难与磨难。
在抛开西游记的宗教外衣下，对今天的青少年来说，这部小说也许更像一个励志故事:人生就要有所追求，为实现理想而披荆斩棘，不畏任何艰难险阻，以超强的韧劲和斗志战胜一切困难，直至胜利的终点。
西游记85到90读后感篇2漫游历史长河，美文佳篇数不胜数，但惟独这西游记让我情有独钟。
它那独特的魅力，令人神往！俗话说：”读万卷书，行万里路”读完西游记，我的精神领域得已更高的升华，灵魂以随此远行。
90年代班主任工作总结(共7篇)
90年代班主任工作总结（共7篇）代班主任工作总结短暂的教育实习，一晃就要落下帷幕了。
回顾这一个月的实习班主任的代班工作。
让我重新衡量了自己的管理和处理事务的能力。
让自己的不足得到重新的检视，在班主任老师的指导下，不断地完善自己。
主要体现在以下几个方面：①班级管理方面：对于中职的学生而言，是“特殊”的学生人群。
这是如何特殊的呢。
首先，他们的年龄段是处于年轻叛逆心理极强的阶段。
其次就是他们大部分学生是因为中学成绩不好，过于调皮捣蛋才就读中职学校的，再有就是父母外出打工，没时间管理他们，或者管理不周到，成绩上不去，干脆就放到中职去，最后有一部分学生来自偏远的山区，受到高级教育有限，接受外界的信息困难。
迫于家庭贫困的压力，选择学技术。
将来能有一技之长。
能养家糊口。
所以在班级的管理上面，必须得另辟蹊径，不能照搬中小学和高中的管理模式和办法。
要找准学生的实际情况，实际需求。
设立一套新的管理办法。
经过这段时间的代班实习，通过对学生的观察与沟通，发现大部分学生都是优秀的，他们并非都是调皮捣蛋的坏坯子，而调皮捣蛋之所以调皮都是希望通过调皮引起老师对他们的关注。
从而希望受到老师的关爱。
因此，作为班主任，首先要对每一个同学进行“补爱”。
从心灵上，给予学生尽可能多的慰藉和关心。
所以和每一个学生，必须要与他们用心交流，多聆听他们内心深处最真实的声音，让后做出相应实效的措施。
在生活上，多到学生宿舍看看，了解学生的生活状况，。
课外活动上，多和学生一同参加，晚自习，多下班走走。
对于班级中的一些调皮的同学，应当单独对话，捉住他的需求，给予更多的关注。
②与原班主任沟通方面：在实习期间，作为副班主任的我们。
虽然大部分管理学生的权利都交给了副班主任，但是班级里的所有事物都应该向他汇报。
特别是学生请假外出，必须请示班主任，还有学校的规章制度，也必须遵守。
在这一个月的实习工作中，学生的请假外出，都请示班主任，小的事务除外。
还有就是班级里，出现的情况必须第一时间和班主任沟通，及时了解学生的思想状况，并与班主任一起解决出现的问题。
7码是90还是100
7码是90还是100是110cm7码是90还是10017码不是90也是100而是110cm。
对于家长来说，选择孩子的服装大小是非常重要的一件事情。
如果选择的服装不合适，孩子会感到不舒服，甚至可能会对孩子的身体健康产生影响。
因此，在选择孩子的服装时，家长需要了解一些基本的知识，以便正确地选择合适的服装。
首先，家长需要知道如何测量孩子的身高。
最准确的方法是让孩子直接站在一个测量高度的地方，例如，测量身高器或墙上的标记，然后使用测量尺来测量孩子的身高。
如果无法进行精确测量，则可以根据孩子的年龄和一些基本的身体指标来确定孩子的身高范围。
然后，家长需要了解如何选择合适的服装大小。
在选择衣服的大小时，家长应该主要根据孩子的体高来选择衣服的大小。
一般来说，根据上述规则，儿童短裤长约等于体高的30%，衬衫长约等于体高的50%，裤子长约等于体高的75%，茄克衫约等于体高的`49%，西装长约等于体高的53%，长大衣约等于体高的70%，女童连衣裙约等于体高的78%。
当然，家长在选择合适的服装大小时，还需要考虑孩子的年龄、体重、身体比例、活动水平等因素。
家长可以根据孩子的实际情况做出适当的调整，以确保选择的服装大小最为合适。
最后，在选择孩子的服装大小时，家长需要选择适合孩子的款式和颜色。
不同的孩子有不同的衣着喜好和风格，家长应该根据孩子的喜好和性格，选择适合孩子的服装款式和颜色，以便让孩子感到自信和舒适。
7码是90还是10024码对应中国几码4码对应中国36码。
在美国，4码一般被认为相当于23厘米的脚长，类似于中国的36码。
在国际上一些英美品牌的'靴子通常使用4码或5码进行计量检测，然而，由于不同国家使用不同的尺码系统，很容易出现误差，因此在购买鞋子时必须仔细确认尺码，以避免选择错误的码数。
如果脚长为厘米，根据欧洲码，应该选择43号的鞋子。
虽然4码等于36码，但中国香港通常使用现代美式和欧洲地区的鞋码规格，男性一般穿42-46号的鞋子（欧洲码），而女性穿36-40号的鞋子（欧洲码）。

4试剂4.1无水乙醇：分析纯4.2无水乙醚：分析纯4.3苯：分析纯5操作方法5.1快速馏分试验将100毫升的原油试样倒入准确称取其重量的恩氏蒸馏烧瓶中，插上蒸馏温度计，在石油蒸馏测定仪上蒸馏至300℃，以除去300℃以前馏分之后，关掉加热器，取下蒸馏瓶拔出温度计，待温度下降到100℃时，准确称取蒸馏烧瓶中所剩的原油（300℃后渣油加瓶重），将蒸馏烧瓶中所剩的原油倒出10～15克于另一烧瓶中，用软木塞将瓶口塞好，将蒸馏瓶移入已预热的接有变压器的凹形电炉中加热，使蒸馏速度每秒约3滴，这一阶段的蒸馏时间不应超过10分钟，将此馏出物称准至0.1克。
进行平行测定，每次平行测定的差值不能超过较小值的1.5%。
5.2含蜡试验5.2.1溶解在两只恒重后的烧杯中平行称取300℃后的馏出物1-1.5克，室温下末凝的馏出物含蜡量较小，将其加热到20℃左右，趁其融熔时，并在不断的搅拌下，加入无水乙醇—无水乙醚（分析纯）1：1混合液将其溶解，溶解后的颜色为透明色，如颜色浑浊或有小油粒悬浮于溶液中则试样溶解不好，则此试样应作废，重新取样进行分析，此时可将加热温度适当提高，使馏出物能很好溶解即可。
在一般情况下，试样与溶剂之比1：10。
5.2.2冷却将盛有已溶解好的混合物的烧杯放入装有用无水乙醇作为冷剂的仪器中，冷却到-18℃至-20℃，在整个冷却过程中，应搅拌混合物，如果停止搅拌，蜡就会形成较大的晶块，这样在吸滤时很难把油洗净，所得的含蜡结果就会偏高，所以在整个冷却过程中，不断搅拌混合物是极其重要的，必须严格遵守。

那我该如何应对用户的谎言呢？
第一，提醒自己要保持清醒，不要被用户的甜言蜜语冲昏头脑。
第二，去设计一些小的实验，就如同意启之前的“傆型”系列去设计一个仿真门或者迎宾实验，去测试一下用户所做的是否等同所说的，使用用户的体验数据代替口头数据来决定下一步做什么。
如上述连环画，如果老板能先改造几个学习房用以测试，是不是就能得到用户谎言下的真实了呢？
2、恶行之“满满的都是解决方案”
在信息化异常发达的时代，用户有很多渠道获取各种知识，你作为一个专业人员去征询用户的需求时，用户甚至会很反客为主地 balabala 对你洗刷一顿倾诉他们的“解决方案”。
是的，用户有个常态，他们喜欢用解决方案来代表需求。
什么叫需求？什么叫解决方案？比如 iPhone 不是需求，它是一种解决方案，它满足的是获得一种不同的生活方式。
而什么是用户的用解决方案说话？比如经典的亨利福特的“我要一匹更快的马”，其实是要更快的速度；又如最近在某次创新活动中遇到的“用户说他需要一个查看培训发布的平台”，其实他只是需要找到靠谱的地方去学习 java。
New Coke 曾经是可口可乐公司的一次营销活动，始于一次可口可乐与百事可乐的宣传之争，那时百事可乐做了一次街边调查，普遍用户觉得百事可乐好喝；出于营销手段的对峙，可口可乐也做了一次类似的调查，可他们惊恐的发现用户还是说百事可乐好喝，而且用户在说如果能更甜就好了，可口可乐听完，马上按照用户的需求去设计了 New Coke 这个加大糖分的可乐，但发售后发现并不是那么回事，甚至是一败涂地，可口可乐立即恢复了原来的配方。
这是为什么？因为当时用户在街边小试，在口渴且少量的情况下，自然是更甜比较好，但作为大瓶的饮料，更甜就显得腻了。
可口可乐犯了一个错误，无条件地遵守了用户的解决方案，而没有在特定的情况下去针对实验的合理性进行分析。
那我该如何应对用户的“满满的都是解决方案”呢？
保持疑心，在遇到用户倾诉时多问几个为什么。
比如，你为什么会需要这个？之前你是怎么解决你的问题的？这样引导用户，或者说引导自己去想清楚用户所说的言语背后隐藏的用意，这样才可以避免被牵引去 do wrong thing。
