The results are as follows : as the sputtering pressure increases, the atomic ratio of o to ti increase in the films, which is attributed to the fact that the absolute oxygen content increases, as the pressure increases despite the ratio of 62 to ar remains unchangless
結果發現:在氧氣、氬氣分壓比不變的條件下,薄膜表面o和ti原子比增大,這可能是由於濺射氣壓增大,而氧氣與氬氣比未變,真空室中氧氣的絕對含量增加,參加反應的氧原子數增加的緣故造成的。Many studies had attempted to characterize chemical weathering process by focusing on geochemisty of river particulate and sediment. the sediment geochemistry may reflect and compare with the carbonates and silicates weathering degree by introducing the chemical index of alteration ( cia ) and new sediment index of variation ( siv ) and elemental molar abundance ratio of the sediment. the one main objective of this study would provide and compare the relative weathering intensities of silicates and carbonates with the different basins
2沉積物地球化學與化學風化進程和機械剝蝕率化學風化指數與化學風化率屬于表徵化學風化作用意義不同的函數,前者為相對概念反映流域巖石在原巖基礎上己發生淋溶作用的深度,主要受到了氣候因子的深刻影響(中國流域沉積物化學風化指數由北到南呈有規則的遞增序列,氣候因子對風化進程的影響掩蓋了巖性的巨大差異) ,而化學風化率含義是指單位流域面積巖石風化淋溶產生的離子絕對總量。Quantum cryptography ( qc ) is the combination of classical cryptography and quantum mechanics. the characteristics of quantum mechanics, such as no - cloning theorem and heisenberg ' s uncertainty principle, provide the perfect secrecy for quantum cryptographic communication
量子密碼學是密碼學與量子力學結合的產物,利用量子不可克隆定理和海森堡測不準原理等量子特性,量子密碼通信理論上已經證明是絕對安全。A relaxation surface effect is simulated on the basis of a molecular dynamics using the eam ( embedded atom method ) potential by applying a periodic boundary condition for copper. surface atom ' s potential, stress and position changes are presented
運用分子動力學方法對納米單晶銅在接近絕對零度下的表面效應進行了分析,給出了表面原子位置變化、能量大小、應力的大小。Three absolute radiometers compare with the solar irradiance absolute radiometer ( siar - 1 ) respectively on ground, and calculate the corrected coefficient of three absolute radiometers relativity to wrr respectively. seven calibrated factors are introduced, and the formula of every calibrated factor is showed, which according to the principle and the work in fact of stim. it can truly calculate corrected coefficient of every calibrated factor by formula
在地面,通過把三臺絕對輻射計分別與同世界輻射基準wrr比對過的絕對輻射計siar - 1進行了比對,分別計算出了三臺絕對輻射計相對於世界輻射基準wrr的修正系數;在空間,結合太陽輻照度監測儀的工作原理及其實際工作情況,研究出了太陽輻照度監測儀星上測量七項校正因子的計算公式,通過這些公式能夠準確地計算出各項校正因子的修正系數。A new method of absolute calibration of photodetector sensitivity based on spontaneous parametric down - conversion ( spdc ) biphoton field is described. the process of spdc is studied theoretically. the single photon detection probability and two - photon coincidence probability are derived and the calibration principle for photodetectors is explained. an experimental system has been set up. the sensitivity of a photon - counting photomultiplier tube was measured, and the results were compared with those obtained using conventional method
討論了一種基於自發參量下轉換雙光子場絕對校準光電探測器靈敏度的新方法,著重推導了對自發參量下轉換過程中產生的單光子的探測概率和雙光子的符合速率,從而闡明了絕對測量光電探測器量子效率的原理.基於這一方法對光子計數型光電倍增管的響應靈敏度進行了測量,並將實驗結果與常規方法測得的結果進行了比較Thus , for instance , it may come as a shock to mathematicians to learn that the schrodinger equation for the hydrogen atom is not a literally correct description of this atom , but only an approximation to a somewhat more correct equation taking account of spin , magnetic dipole , and relativistic effects ; and that this corrected equation is itself only an imperfect approximation to an infinite set of quantum field - theoretical equations
因此,舉例來說,對數學家而言,了解到下述情形可能會令其驚愕不已,即薛定諤( schrodinger )的氫原子方程式並非是對該原子作出的一種絕然正確的描述,而僅僅是個近似值,趨近於一個在某種程度上更為正確的將自旋、磁性偶極子、以及相對論效應考慮在內的方程式;而這個得以糾正的方程式就其本身而言也只是一個不完美的近似值,趨近於無窮無盡的一整套量子場論方程式。The theory stated that at temperatures near absolute zero, the atoms could reach a state of such low energy that they collapsed into a new state where it was no longer possible to distinguish between them - a state known as einstein - bosecondensation
