We propose a technique to precisely measure the line width of the photoassociation spectra of the excited cesium molecule by using a frequency shifter to generate two laser beams with a precise frequency difference. A series of photoassociation （PA） spectra are recorded with two laser beam induced molecular lines, whose peak separation serves as an accurate frequency ruler to measure the line width of the PA spectra. The full width half maximum line width was studied as a function of PA laser intensity. The extrapolated value at zero laser intensity is （34.8± 0.22） MHz. By analyzing other broadening mechanisms, a value of （32.02 ± 0.70） MHz was deduced. It is shown that this scheme is inexpensive, simple, robust, and is promising for applications in a variety of other atomic species.

Different from the oxidation kinetics of other nitrides,the oxide layer on AlN can easily reach tens of micrometers at a temperature above 1200 ℃.In the present study,the oxidation mechanism of AlN is investigated through microstructure *** analysis indicates that the oxide layer is full of small *** formation of pores generates additional surface area to induce further *** reaction thus controls the oxidation in the temperature range from 1050 to 1350 ℃.The oxidation rate becomes slow as the oxide layer reaches a critical thickness.

针对降雨预报不确定性带来的汛期预泄风险问题,提出基于CFS预报产品的水电站水库预泄决策方法。利用CFS历史预报数据,建立不同预见期特定预报降雨条件下的实际降雨和入库流量的概率分布,计算不同库水位和发电决策组合下的弃水风险率。在常规调度的基础上,根据CFS降雨预报信息,以弃水风险率为决策依据,以优化的弃水风险率阈值为预泄幅度的定量指标进行调度。实例研究表明,该方法简便易行,充分利用了降雨预报信息,在汛期可提供定量化预泄决策,兼顾了效益与风险,达到了减小弃水的同时增大发电量的目的。

The transition dipole moments（TDMs） of ultracold85 Rb133 Cs molecules between the lowest vibrational ground level, （X^1Σ~＋（ v= 0, J= 1）, and the two excited rovibrational levels, 2~3Π0＋（v′= 10, J′= 2） and 2~1Π1（v′= 22,J′= 2）, are measured using depletion spectroscopy. The ground-state85 Rb133 Cs molecules are formed from cold mixed component atoms via the 2~3Π0-（ v= 11, J= 0） short-range level, then detected by time-of-flight mass spectrum. A home-made external-cavity diode laser is used as the depletion laser to couple the ground level and the two excited levels. Based on the depletion spectroscopy, the corresponding TDMs are then derived to be 3.5（2）×10^（-3）eαα and 1.6（1）×10^（-2）eαα, respectively, where 0）（60 represents the atomic unit of electric dipole moment. The enhance of TDM with nearly a factor of 5 for the 21Π1（v′= 22, J′= 2） excited level means that it has stronger coupling with the ground level. It is meaningful to find more levels with much more strong coupling strength by the represented depletion spectroscopy to realize direct stimulated Raman adiabatic passage transfer from scattering atomic states to deeply molecular states.
