中文拼音 [hésùfēngdù]
核素豐度
英文
nuclide abundance-
The obvious overabundances of heavy - element are observed in ba stars. however, the luminosity of ba stars is too low to reach agb stage, and the nuclear 99tc have not observed in ba stars
鋇星的重元素是過豐的，但其光度太低，認為還未演化到agb階段，而且並沒有觀測到~ （ 99 ） tc核素。The average abundance distributions of heavy elements in metal - poor stars can provide fairly direct and detailed information on the nucleosynthesis in every stage after the formation of galaxies. furthermore, it can put more accurate constraints on the chemical evolution of neutron - capture elements. the solution to this problem will have important effect on the solution to a series of problems about nuclear astrophysics and the galactic evolution
貧金屬星的中子俘獲元素豐度分佈能提供星系形成后各個階段核合成的較為直接和詳細的信息，並為星系化學演化的研究提供更為準確的約束，這一問題的解決將對核天體物理及星系化學演化的一系列問題的解決產生重要影響。Synthesis and characterization of rare earth tb3 - trimesic acid fluorescence complexes
過程核合成的場所和重元素豐度的離散The abundance of feed nuclei 6fe of s - process is proportional to metalicity
Fe族元素作為種子核，金屬豐度與[ fe h ]成正比。Simultaneously, enhancement of the cross section must has had been played an important role in astrophysical nuclear process. we investigate the s - process of nucleosynthesis of heavy element of astrophysics and give a group of analytic solutions for the s - process. to check up the analytic solutions, we calculate the n distributing of the heavy element of s - process in solar system and the result is good agreement with astronomic measurement
我們研究了天體重元素核合成的s ?過程，給出了s ?過程網路方程的一個解析解，作為對本文解析解的檢驗，我們計算了太陽系的s ?過程重元素豐度的n分佈，計算結果與天文觀測符合的較好；另外，我們還計算了s ?過程的典型分叉點~ （ 85 ） kr處各個核素的豐度變化，與已有的結果符合的較好。The research of human resource value measure models of this paper has very important theoretical meaning and realistic significance. under the guidance of marxian labor valve theory and occident human capital theory and element distribution theory, this paper aims at the high science & technology software development enterprise and designs model systems of human resource group value and individual value measuring, which not only adhere the traditional accounting principle, but also combine qualitative analysis with quantitative analysis. in detail, it is organized as follows : ( 1 ) according to some defects of the available value measuring models, this thesis brings forward 4 innovative trains of thought : adopts the method that combine qualitative analysis with quantitative analysis, and establishes the new measuring basis that contain human resource the present period input cost and realized value, and defines the high - grade human resource as the target evaluation group of individual value measuring, as the basis for revealing the real contribution of human resource group firstly and achieving individual value by distributing group value to the target evaluation group in according with the specific rules secondly ; ( 2 ) analyzes the constitution of human resource value, and comes up with new way of thinking on group value measuring : adopts the historical cost means to calculate human resource group the present period input cost, and rectifies the present period realization value theory of li - shicong professor from accounting angle, and obtains more scientifically the group present period new contribution value, as the basis for structuring the new measuring
首先揭示組織中人力資源群體對企業的真實貢獻，然後再將群體價值以一定的規則分配給目標評估群，從而確認個人價值; （ 2 ）分析人力資源的價值構成，提出新的群體價值計量思路:採用歷史成本法計量群體當期投入成本，並對李世聰教授提出的當期實現價值理論從會計學角度進行了修正，更為科學地確定了群體當期新增貢獻價值，從而構建了全新的人力資源群體價值計量模型; （ 3 ）分析個人價值的影響因素及其關系，提出新的個人價值計量思路:運用層次分析法獲得目標評估群在群體當期新增價值中的權重，確定高級人力資源當期所創造的貢獻份額;基於崗位相對權重和個人崗位績效評估值這兩個關鍵指標，將層次分析法和關聯矩陣法結合起來，計算個人貢獻價值系數，確定某個體在目標評估群中的權重，從而構建了全新的人力資源個人價值計量模型; （ 4 ）選取了一家人力資本含量較高的it公司，將所構建的理論模型在該公司進行了實證檢驗，驗證了模型體系在實務中的科學性與可操作性，從而在一定程度上豐富了人力資源價值計量理論，推動了人力資源會計與現行會計核算體系的接軌。分享友人
