We have synthesized a variety of alkali-metal and ammonium fluorosulfatometallates (titanates, zirconates, and hafnates). The alkali fluorosulfatozirconates and fluorosulfatohafnates have been shown to exhibit efficient roentgenoluminescence (RL) in the UV through visible spectral region, with a maximum at 390–440 nm. Their RL spectra depend significantly on their composition (cation, anion, and water content), coordination of KF and K2SO4, and relative amounts of fluorine and SO4 groups. We have examined the effect of heat treatment on the RL of these compounds. The rubidium and cesium fluorosulfatozirconates Rb3Zr2F9SO4 · 2H2O, Cs2ZrF2(SO4)2 · 2H2O, Cs8Zr4F2(SO4)11 · 16H2O, and Cs2ZrF4SO4 offer the most efficient RL. 相似文献

The behavior of wall-bound drops and bubbles is fundamental to many natural and industrial processes. Key characteristics
of such capillary systems include interface shape and stability for a variety of gravity levels and orientations. Significant
solutions are in hand for axisymmetric pendent drops for a variety of uniform boundary conditions along the contact line with
gravity acting normal to a planar wall. The special case of a wall-bound drop or bubble that is also pinned at an edge (i.e.
a ‘wall-edge-bound’ drop) is considered here where numerical solutions are obtained for interface shape and stability as functions
of drop volume, contact angle, fluid properties, and uniform gravity vector. For a semi-infinite zero-thickness planar wall
(plate), a critical contact angle is identified below which wall-edge-bound drops are always stable. The critical contact
angle is computed as a function of the gravity vector. The numerical procedure, which makes no account for contact angle hysteresis,
predicts that such wall-edge-bound drops are unconditionally unstable for any gravity field with a component that is tangent
to the wall while inwardly normal to the edge. Select experiments are conducted that support the conclusions drawn from the
numerical results. 相似文献

计量仪器收发工作是沟通计量检定部门以及送检单位之间的桥梁,也是计量检定工作的前提。随着各级计量技术机构业务量的不断增加,计量技术机构除了要树立顾客至上的服务理念之外,同时还要用专业、高效的管理模式来赢得顾客的信赖与认可。在计算机信息技术的不断发展与更新的大环境下,传统的管理模式已经不能适应计量检测工作的需求,因此,要有效的利用网络信息技术来促进计量仪器收发业务管理模式的创新,进而提高计量仪器收发业务管理的工作效率。 相似文献
