今天把它套在镜头前，结果对不上焦了。 拍出的照片模糊并且曝光不足。
高手解答一下该怎么弄，才能对上焦，拍出清晰明亮的照片？ |

发帖数: 401 | 25 In n-dimensional euclidean space R_n, we have a vector A and a subspace S
that belongs to R_n. What is the maximal angle between A and any vector B in
S?
I have some exposure to linear algebra, but am not sure if the problem is a
well solved problem. Any recommendation on keyword, book, paper or web link
will be highly appreciated.
Thanks. |

发帖数: 241 | 26 请问在真空里(相对于在空气里)，水和固体的接触角(CONTACT ANGLE)有何改变啊？
Thanks a lot! |

发帖数: 2539 | 27 the contact angle of a water-air-solid system is determined by Young-Laplace
eqn, and is a function of water-air surface tension, air-solid surface
tension and water-solid surface tension.
comparing your two cases, water-vacuum and water-air, two parameters change,
water-air -> water-vacuum, and air-solid -> vacuum-solid.
u may need some detailed analysis.
btw, liquid can't stay in vacuum long, it's gonna evaporate anyway.
in this case, the problem turns to a water-vapor-solid system. |

发帖数: 149 | 29 thanks first
my sample is 3*7 mm^2
and the detector area is 10*10mm^2
the distance between sample and detector is 2mm
how can I calculate the solid angle the detector coverd, any formular?
does it depend on the sample size or I can use a point for the sample?
try to google to find answers, more and more confused...
thanks again |
