X - ray flashes had previously been detected from some neutron stars, but they never exceeded the eddington limit by very much
以往天文學家就曾觀測到過從中子星發出來的x射線閃光,但其亮度從來不會超過艾丁頓上限太多。It was first being used in america. since january 2002, the dovs of cuhk has been conducting pioneering clinic studies on ppt. more than 300 patients have been recruited to investigate the accuracy, safety and patients degree of acceptance in using the new device, in comparison with goldmann applanation tonometry, the gold standard for measuring iop
閃光眼壓計最先在美國使用,香港中文大學眼科及視覺科學學系從二零零二年一月起開始進行這方面的研究,迄今已成功用於超過300名病人身上,並分析了閃光眼壓計的準確度、安全度、及病人接受程度。We have the following results through simulation and experiments : i ) turbulent structure constant of atmosphere decreases with altitude ; ii ) turbulence induced power scintillation decreases with the optical wavelength ; iii ) scintillation of space - to - ground optical propagation is smaller than that of horizontal optical propagation ; iv ) power scintillation of space - to - ground optical propagation increases with wavelength ; results above are accord with existent theory. what ' s more, the last result discovers a new rule
通過對數學模型和模擬結果的分析,得到以下結論: a )大氣湍流結構常數隨海拔高度的增加而迅速減小; b )由湍流引起的光功率閃爍與波長呈反比; c )空-地激光通信的光功率閃爍小於地面水平傳輸的閃爍; d )空-地激光通信的光功率閃爍與波長呈正比;上述結果與理論保持一致。Yet ingenious astronomers throughout history still perseveringly hacked their way to measure the distances of these celestial bodies purely by their twinkling, obscure lights
然而,古往今來無數的天文學家卻以無比的智慧和毅力,試圖憑藉點點閃爍不定的星光去測度天體間的距離。Although light waves in the regime of classical optics can have electric fields as strong as those near bolts of lightning, these fields are not effective for accelerating particles on their own, because they oscillate transversely
在古典光學中,雖然光波的電場有可能大到如閃電雷擊的程度,但因為電場是以橫向振蕩的,所以無法有效用來加速粒子。1 measurement items : luminance ( transmittance, grey scale inversion ), chromaticity, response time, flicker, eoc, gamma curve, view angle performance, spectrum, reflective luminance, reflective chromaticity, reflectivity, module optical performance with certain temperature range
1量測項目:亮度(穿透率,灰階反轉) ,色度,響應時間,閃爍度,光電特性曲線,圖像輝度曲線,視角特性,光譜曲線,反射亮度,反射色度,反射光譜,反射率,產品光學參數的溫度特性。分享友人
