发帖数: 2 | 2 Dear Mathematicians:
I am a hydrogeologist from a US national lab and need help with solving the
following problem. If any one can solve the problem, I would like to invite
him or her to coauthor the paper that I am working on now.
-1/2*df/dh=d(df/ds*dE/dx)/dx+d(df/ds*dE/dz)/dz
where
d =partial derivative sign
E=h+z
f=f(h,s)
h=h(x,z)
s=(dE/dx)**2+(dE/dz)**2
Need to find a function G(h,s) such that the above equation can transformed
to
d(GdE/dx)/dx+d(GdE/dz)/dz=0
Thanks in advance! |

又到全国两会召开之际，全国政协委员高杰并没有忘记他的梦想：让国际直线
对撞机(International Linear Collider，简称ILC)落户中国。
2008年3月，首次当选全国政协委员的中国科学院高能物理所研究员高杰，在
全国两会期间提出一份提案，建议中国抓住历史机遇，适时申请成为国际直线对撞机的
承建国。
高杰告诉《科学新闻》，今年他的提案仍会涉及国际直线对撞机。他的这份提
案建议政府成立中国战略发展中心，而关于国际直线对撞机的事宜，“就应该由这个中
心来协调各方面的利益和声音，为国家战略决定提供科学决策”。
为了推进战略实施，国际未来加速器委员会(ICFA)责成其下属的国家直线对撞
机指导委员会(ILCSC)制定ILC全球战略。ILCSC在2005年初成立了全球设计工作组(
Global Design Effort，GDE)。GDE是由60多位科学家和 |

刚看了一则新闻关于麦当劳转卖的新闻，对于中国的食品安全，我总是千百个担忧，有
