我用的青轴，用黑轴就觉得有点费力。也没有click的声音 |

filco一半，这些也算不上缺点了 |

刀头纳米处理,, 但角度车 对比分析, 做曲线
温度梯度变化, 得数据, 做曲线分析
针对不同材料做切割, 得数据做分析
可以发表在MECHNICAL杂志上. 只是如果不赚钱的话, 车工发表文章确实无用. |

This is a typical problem that can be solved by using the shooting method. The
shooting method is a commonly-used method in numerical solution of nonlinear
dynamical differential equations. Just look up this method in mechnical or
applied mathematical journals. Good luck. |

发帖数: 38 | 14 Here are my 2 cents although I am not working on fluid mechnics.
On the numerical side, try preconditioned GMRES if Gaussian elimination with
pivoting does not fail.
If the previous does not work, check out whether the system of equations is
diagonalizable.
Finally, if this is an eigenvalue problem, try to solve it as an eigenvalue
problem.
good luck.

发帖数: 73 | 15 I have a Ph.D. in mechanical engineering-bioengineering. I am now a postdoc
in a medical school. I am in my 30's, female, single. I have been thinking
about going to law school but I have a few concerns.
1. shall I go for part-time or full-time law school?
I have tried to applied for the tech specialist position in the IP law firm.
No one wanted to hire me. I guess the reasons can be: first, they don't
need my technical background. It seems like other majors such as biology,
biochemistry or c... 阅读全帖 |

条路或许不适合你。坚持去上law school的话，lz你要做好50%可能找不到工作的打算。
2.单从law school录取来讲，LSAT最重要，GPA也有点用，你的strong publication可

3.结婚不占你什么时间，生孩子可以放在第三年，都是doable的，只要你那时候已经有

工作找不到，估计让你生你也不敢生。

2. A lot of people consider law schools (especially non-top schools) as a scam. Huge debt without a job or with a $50k job ?
3. Question for you
Person A, PhD with 1 year part-time patent prosecution experience OR with patent bar w/o experience
Person B, JD with patent work experience
Person C, JD+PhD without experience
Who is better positioned for today's IP job market?

发帖数: 103 | 22 Thanks for all the help I got when I was going for an on-site in UTRC. This
board is very good and supportive. Here is my two-cents about interview ,
working etc. Sorry about English because I am very slow in inputing Chinese.
Actually my major is not ME, I worked with a lot of mechnical engineers over
the years. My major is optical engineering. Still I think some of my
lessons will be good for ME people.
The first lesson is that : we do not have a lot of bargin power when we were
just fresh out |

准备好interview问题，为什么读了数学博士，想来做mechnical engineer?
哪儿可找到一些范文？

发帖数: 2539 | 24 是，严格来讲你这个确实不是exact的伯努力方程。
严格的伯努力方程的推导有两种，无粘流体机械能守恒，或者欧拉方程里的动量方程沿
流线的积分。两种情况得到的最终方程是一样的，对不可压缩流体。
P_static + 1/2 rho u^2 + rho*g*h = constant
注意这里头一个非常重要的假定就是 “无粘”。
你的方程一般称为Bernoulli's equation with head loss，也就是考虑能量损失的伯
努力方程，一般很少被称为energy conservation equation，或许称之为mechnical
energy conservation是可能的（我不是很清楚）。在民用设计，计算里很常用，比如
说消防队计算水头什么的。湍流和层流并不是判断伯努力方程能否适用的准则，比如在
一段直圆管内，只要有摩擦，不管是层流还是湍流，严格的伯努力方程都失效，因为你
不能假定 “无粘流体”。这个时候要考虑沿程损失，而且要使用Bernoulli's
equation with head loss，就是这样的：

Among the books you mentioned, I like Reichl best, because it is very
comprehensive ( I haven't read 1. and 3.) I would also like to mention
Feynman's book on statistical mechnics. Although non-traditional, it is
very readable. |

发帖数: 53 | 30 One doesn't really need to invoke relativity
when saying that "all inertial frames are equivalent".
We have such notion in Newtonian mechnics already. There
we mean the equation which dictates the dynamics of the
system, namely F=ma, is invariant when we change from one inertial
frame to another, i.e. when we make a Galileo transformation.
The underlying reason for F=ma's invariance is that the difference
of two position vectors is invariant under this transformation.
In short, the equivalence o |

发帖数: 160 | 31 To talk about the quantization of time in quantum mechanics, it definitely
benefits to briefly review the background on general issues about "time" in
quantum mechanics and the plcae where the problem took its origin. I am not
quite familiar with the research on this topic and can only give a brief
review, plus some of my own ad hoc thoughts without much cautious analysis.
