  1. To reduce the marking distortion, using the vertical 2 - dimension galvanometer distributing and f field lens focalize, the distance of the second galvanometer to the machining plane is the focus f. to avoid too hign temperature to distroy the resonance cavity because of too long marking time, cooling system and self - protector is used in the design

    為減少打標畸變,採用垂直維振鏡分佈, f物鏡聚,將激光束經個振鏡反射後到加工平面的離為f ,為了避免打標時間過長,溫度過高破壞諧振腔,在設計中加上冷卻系統和自我保護裝置。
  2. 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、垂直聚單色器在不同起飛角下的聚曲率半徑和傾角;討論了準直器的尺寸和發散,以及使用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、離樣品遠近對強度損失和測量中的影響做了深入研究。
  3. The second property concerns the brightness of a projected image, which depends on the focal length and facial, or surface, area of the imaging mirror

    項考慮的特性是投影的明亮度,這要視與鏡面(鏡子的表面)而定。
  4. My finding about the unlikely focal length of the putative projection mirror has a second implication, even more constraining to the hockney theory

    既然設想中投射鏡的不太可能實現,我的發現還延伸出個推論,更使霍克尼的理論受限。
