2017年新年快乐！
踏入2017年，我也即将迎来人生的第二十五个年头。
在这一年中，要自制、自律、自强。
生活上，希望能够通过适当的锻炼提高肌肉水平，保持健康，健身塑形。身体无论在任何时候都是最重要的本钱。将生活习惯通过适当的方法导入规律的模式，以此促进自律能力的复建，以期建立良好的习惯循环。
学习上，已经在硕士的第一个学期渐渐掌握留学的重点要点，有惊无险地通过了考试，获得了不算差的成绩。希望在2017年能够进一步提升成绩，争取获得“优秀”级别的评级。英语能力必将是终身重视的项目，2017年，希望可以尽力接近雅思7分的水平。不忘初心，决定重拾德语，希望2017年能够通过自学达到A1的水平。一些必要的专业能力无疑是个人竞争力的核心项目，课外的自学非常必要。
谨此勉励自己，勇敢地在2017年发现、探索、提升、跃进。

我大概从2003年开始，除了看父母订阅的期刊，也系统地给自己订阅自己喜欢的期刊，包括军事、航空、自然类的，虽然只是业余期刊，但也一种能够维持阅读量的重要方式，为我的知识储备提供了巨大帮助。特别是当时网络和计算机并不如今天发达，许多课外知识除了公共媒体，大概就是通过期刊了。也正是通过期刊，我意识到了“知识领域”的概念。
I started to subscribe and read journals for since 2003, for myself. Apart from those journals my parents subscribed, I keep reading about military, aviation and nature. Even though they are “hobby” papers, I did fetch tones of knowledge from them. Especially when it was the time that Internet and smart devices were not that popular. And I set up the knowledge structure called “knowledge fields” thanks to these journals.
想来自从读大学离开家以后，就没有非常认真地定量定期的阅读期刊，剩下的时间都在网络上获取碎片化知识了。阅读能力、知识获取效率都大幅降低。
Unfortunately I lost that habit in my undergraduate years, all I did are collecting fragmented knowledge. My abilities of reading and knowledge absorbing are degenerating.
近来决定还是要恢复一下阅读期刊的习惯。正好学校的网络可以通过各大文献库免费获取各种专业、业余期刊，求之不得。
It is horrible that a person lose his ability to read. I must find something to read in regular time and regular quantity. It is easy to fetch professional and hobby journals from journal database for free with my university authorization. Cool!

虽然已经学了十来年的英语，但是见到牛津图解词典的时候还是觉得实在是一本很优秀的全年龄段英语词典。绘图之精美简直就是一本画册。此书可以拿来提示生活常用单词，也可以作为英语初级学习者的优秀材料。
Even though I started my English learning decade ago, I was impressed by this dictionary. Gorgeous pictures in this book will make you feeling that it is a gallery instead of a dictionary. Suitable for vocabulary reminder and primary learner of English. |

其实这个就是之前谈过的莫迪图查询器， 但是后来因为学习上比较忙，就没怎么研究。这两天看了一下，似乎并不需要做莫迪图查询器这么复杂，只需要根据输入参数代入逼近公式运算就可以得到所求摩擦系数。具体需要利用JavaScript来实现，通过输入的参数，在服务器端按照逼近公式计算，显示运算结果。
Actually, it is the moody chart checker I have mentioned before, but I was too busy for my courses to think about how to develop the checker. In these few days I found that there is no need to build a chart checker, a web calculator will work. Input necessary values and calculate with equation approximation, the display the result on the page. JavaScript will be used to develop the calculator.
按照Darcy friction factor formulae中提供了很多种逼近公式。
Darcy friction factor formulae shows many equation approximations.
首先尝试了一下Alashkar公式。
Try the Alashkar equation.
运算部分的JS中代码大概如下：
Calculation part of the JS code:
[code language=”javascript”]
function cal(form)
{
var a=Number(form.a.value);
var b=Number(form.b.value);
var c=Number(form.c.value);
var d=a/(b*3.7065);
var e=2.5226/c;
var f=1.665368035*e;
var g=Math.pow(f,0.8373492157);
var h=d+g;
var i=Math.log(h);
var j=e*i;
var k=0.8784893582*j;
var l=d-k;
var m=Math.log(l);
var n=e*m;
var o=0.8686068432*n;
var p=d-o;
var q=Math.pow(o,-2);
var r=Math.log(q);
form.s.value = 1.325474505*r;
}
[/code]
然而求出来的结果似乎并不对。还需要再研究研究。
It works but the result is strange, more research to do.
