焦距儀檢定規程Contact lenses. determination of back vertex power. method using focimeter with manual focusing
接觸鏡片.后屈光度的測定.利用手工聚焦法使用焦距儀的方法The position and size of the monochromator, focusing curvature radii and tilting angles of the germanium focusing monochromator under different different take - off angle, size and divergency of the second collimator and intensity loss due to the use of it were determined. the neutron flux at different wavelength, under different reflection and take - off angle of the monochromator and divergency of the first collimator, were given. the simulation on the aperture used for limiting beam size in front of the sample showed that, smaller the size of the aperture and further the distance from the aperture to the sample, greater the loss of the intensity and more serious the spread of the beam along vertical direction at the sample position which makes the practical sampling volume greater than expected
用蒙特卡羅模擬方法對中子應力衍射譜儀的設計方案進行了優化研究，提出了一系列可供參考的數據：確定了單色器的位置、尺寸、垂直聚焦單色器在不同起飛角下的聚焦曲率半徑和傾角；討論了第二準直器的尺寸和發散，以及使用第二準直器造成的強度損失；給出了在不同單色器反射面、起飛角、中子波長和第一準直器發散度的情況下樣品處的中子注量率，以及多種組合情況下譜儀的解析度曲線；對限束方孔的尺寸、距離樣品遠近對強度損失和測量中的影響做了深入研究。Optics and optical instruments. focimeters
