In this paper according to the radiation environment of Beijing Electron Positron Collider (BEPC) synchrotron radiation hall, the neutron detector design is finished by using MCNP cord. Then the calibration and physics test of detectors are finished. Using the detector the measurements of radiation level in BEPC synchrotron radiation hall were carried out. The measurement of high energy dose rate...
Harmonic conjugate is one of the most important and basic theories in projective geometry. According to the theory of projective transformation, the vanishing point's coordinates can be obtained, after that, combined with the corollary of Laguerre theorem: the infinity points of which the two mutually perpendicular lines and their circular points harmonic conjugate, the image coordinates of the circular...
