发帖数: 1471 | 11 拿流体力学来说吧，流体的流动是客观存在的物理现象，传统的N-S方程是对这个物理
现象的数学描述，加上有限体积法这样的数值方法配合适当的边界条件，就是对流体机
械运动规律的一个建模，也就是numerical modeling。你提出一个新的湍流模型，那就
是一个新的numerical model。搞CFD的人设置各种各样的边界条件去模拟各种流体的运

for citations I often disabled it when
using natbib.sty.
sometimes when I made a mistake whey typing,
it would automatically switch to numerical
citation. I had to go back searching for errors.
but now I want to use numerical citation,
it just didn't make a number sequence in
the reference, no matter how I tried.
any possible places I should adjust?
any suggestions?
the number sequence I mean
for example:
[1] alex, a., bob, b., ....
[2] cox, c., dude, d. |

把natbib设成numerical然后在里面引用的时候用
citep{}引用就可以得到你要的效果了把
These examples are for author–year citation mode. In numerical mode, the re
sults are different.

I am not sure about what problem might occur in the numeric
integration. Just
some suggestions:
1) when r is quite large, sin(kr) is oscillating quite fast, thus
usually you
need to take smaller time-steps to take care of it.
2) since you choose g(k) =1, then \int_0^\infty 1/k sin(kr) dk is not
absolutely
integrable, thus there might be some problem when k is small, where
1/k is quite
large, causing some numeric problem.
good luck. |
