| | The phase transitions, thermal stabilities and crystal structures of strontium iodate, barium iodate, calcium iodate, zinc iodate and cadmium iodate have been investigated by means of X-ray powder diffraction and thermal analyses. The possibilities of formation of complex compound between divalent iodates have been studied. The stability of hydrated divalent iodates is expected to be related to the electronegativity of the corresponding cations. | | 本文用X射线粉末衍射与热学分析等方法对碘酸钡、碘酸锶、碘酸钙、碘酸锌、碘酸镉的相变过程、热稳定性和结构进行了研究。对二价碘酸盐之间形成复盐的可能性也进行了探讨。并讨论了二价碘酸盐水化物的稳定性与阳离子电负性的关系。 | | 文摘来源 | | Visible and infrared d.c.e.l.emission has been observed in thin films of ZnS:Cu:Nd:Cl prepared by co-evaporation in vacuum.The lifetimes of the excited states of the Nd3+ ion and the emission intensities at various wavelengths have been studied as a function of temperature and applied voltage.The energy distribution of the conduction band hot electrons taking part in the electroluminescence excitation process has been shown to follow a Boltzmann function and the mean energy of the hot electrons has been fou... | | 在真空中用共蒸发方法制的直流电致发光薄膜ZnS:Cu,Nd,Cl,实验中测量了它的可见和红外发射。本文研究了Nd~(3+)离子的各个激发态的寿命各个辐射波长的发射强度与温度和外加电压的关系,发现导带中参与电致发光激发过程的热电子能量分布遵从玻尔兹曼函数,热电子平均能量是0.16eV左右,这个值和能量转换效率测量结果相一致。 | | 文摘来源 | | In order to increase the thermal efficiency as well as to improve the running stability and to decrease the fuel consumption of a dual chamber stratified charge engine under low load eonditions, a water analogue experimental equipment is developed. This paper describes the principle and construction of this equipment and explains its use in the analysis of the stratification and mixing of the mixture in the sub-chamber. | | 为了进一步提高分隔燃烧室式分层给气内燃机燃烧过程的热效率,并改善低负荷时的工作稳定性和经济性,我们设计和制造了一台水模拟装置,用以研究副室中混合气的分层与混合。本文介绍该水模拟装置的原理和结构,并介绍运用该装置研究副室中混合气的分层与混合的情况。文中所附的示意图是按高速摄影照片描绘的。这些示意图显示出不同的结构和运行情况对副室中混合气的分层与混合的影响。 | | 文摘来源 | |   | | << 更多相关文摘 |
