1.Fa(atomic ratio of Fe/(Fe+Mg)×100) value(with a range of 34.1 mol%~42.2 mol%) and percent mean deviation(PMD) value(6.1) of olivine reflected some degree of thermodynamics equilibration in olivine.
2.Using principle of eletronegativite equaligation to estimate atomic charge was putforward by Sanderson. Sinceit is difficult to find the value of electronegative in commontextbooks. We can get satisfactory result by using popular pauling eletrongativite tocalulate.
3.This paper introduces a new method which can obtain the extinction value linear to the concentration for the atomic absorption spectrometry (AAS) and atomic resonant fluorescent spectrometry (ARFS).
4.The results indicate that the value of squeezed component of the atomic dipole, squeezed frequency, amplitude and squeezed direction of the atomic information entropy ca be controlled by choosing the atomic initial state, the velocity of atomic motion, the field structure and the squeezing factor of field and the squeezing phase angle of the field, respectively.
5.Because of above reason, this method could not widely used . Based on the principle of Atomic Frequency Standard,This paper introduces a implemention of DDS which is based on CORDIC algorithm. this algorithm can retrieve the value of DDS by the basic process such as addition ,subtraction, shift.
6.The band gap almost keeps constant, about 3.27 eV. The film deposited at -300 V exhibits atomic smooth surface, and Rrms is about 0.113 nm, which results in the highest refractive index, nλ=550 nm=2.51, which is more than or equal to the maximum value reported.
7.The results showed that both the ALCTE value of Al-32%Mg-6%Zn(atomic concentration) alloy heated from 28? ℃to 448? ℃and the one of Al-15%Cu-9%Mg-0.04%Be alloy heated from 25?
8.Using ab initio plane waves ultrasofi pseudopotential method based on generalized gradient approximation(GGA),the lattice constant is calculated of CaTiO_3,the total energy and the cohesive energy,the former of which is in good agreement with the experimental value,and then analyzed the effects of Ti atomic Z coordinate on the energy structure and Density of State of CaTiO_3.The electronic structure of CaTiO_3 was influenced intensely by the location of Ti atom.
9.We study the time evolution law of the atomic response in an open Λ-type inversionless lasing system when the probe or driving field is off-resonance,and compare the law with that obtained when the probe and driving fields are resonant.We find that the detuning has considerable effects on the time evolution law:When the probe or driving fields is off-resonance,the dispersive responses for the probe and driving fields are no longer 0 and the two-photon coherence is no longer a pure real;The variation of the probe detuning can make the time evolution law of the population distributions and the gain (absorbtion) of the driving field changing obviously;With detuning increasing,the time evolution behavior of the gain (absorbtion),dispersion of the probe field and the two-photon coherence will gradually diviate from the evolution law of the standard damped oscillator;With the driving detuning increasing,the oscillating time of the dispersion of the driving field becomes longer,the amplitude and the stationary value increase.
