通過分析發現,評價次級中子能譜數據所採用的蒸發譜模型大都忽略了能級密度參數與激發能之間的關聯。Abstract : we have studied the polarization beats spectroscopy with phase - conjugation geometry in a cascade three - level system. it was found that the accuracy for the energy - level difference measurement is determined by the homogeneous linewidths of the optical transitions. under the condition for the occurrence of beating, the frequency difference of the beat between two independent light sources could exceed the laser linewidth. the measurement accuracy for laser absolute frequency could reach the same order of magnitude as the laser linewidth
文摘:研究了級聯三能級系統中的相位共軛極化拍頻光譜術.發現其對能級差的測量精度決定於光學躍遷的均勻增寬.在符合拍頻條件時,兩獨立光源拍頻的頻差可以超出激光線寬,激光絕對頻率的測量精度可達到與激光線寬同一量級By use of g. d. shen ' s tunneling cascade theory we have fabricated high performance and high power tunneling cascade ingaas / gaas / algaas 950nm / 990nm double wavelength strained quantum well lasers on the basis of former tunneling cascade high power lasers and high brightness light emitting diodes. the lasers " two peak wavelength are 95 ? nm and 990 ? nm. el spectrum ' s fwhm is 3nm
在以往隧道級聯大功率應變量子阱激光器及高亮度發光管的理論研究與實驗的基礎之上,採用沈光地教授提出的隧道級聯思想,成功研製出基於ingaas gaas algaas材料的高性能大功率隧道級聯950nm及990nm雙波長應變量子阱激光器,激射波長分別為952 2nm和990 2nm , el譜的譜線寬度約3nm ,未鍍膜器件單面最大輸出光功率可達2w以上,閾值電流最低達120ma 。Internal waves are a kind of bridge relating the diapycnal mechanical mixing to external sources of mechanical energy : first, internal waves are driven by wind stress and barotropic tide so that large amount of mechanical energy are transported to abyssal ocean with propagation of internal waves ; second, the mechanical energy can directly be cascaded to mixing through instability and breaking of internal waves
內波是外界提供的機械能與混合之間聯系的橋梁之一,一方面風和潮汐通過激發內波,將能量向深海和大洋內區傳遞,另一方面,內波的不穩定和破碎直接將機械能串級到小尺度湍流混合中去。開展傾斜地形上內波的傳播以及內潮的產生等方面的研究對海洋混合過程的參數化以及混合對大洋環流的影響等方面的研究具有重要的科學意義。Mapkks ( mitogen - activated protein kinase kinases ) are the key components in the signal transduction passways which regulate a variety of cellular processes in eukaryotes including in plants
