荧光显示管直丝氧化物阴极有效逸出功的计算

阴极的逸出功是表征阴极发射能力的物理量，求定荧光显示管直丝氧化物阴极有效逸出功时，因其零场发射电流密度难于准确取值，温度无法直接测量，显得困难，须予解决，为此提出了一种计算阴极有产逸出功的办法，对某显示管的发射欠佳和“低温高效”的两种氧化物阴极的有效逸出功进行计算，有效逸出功率是靠测量相关物理量再同计算得出，精度不很高，文中所用办法也不例外，但所得结果能反映阴极发射能力，所需仪器少，是实用方法。     

Model for Nanoscopic Domain Formation in Dipalmitoyl-PC/Dilauroyl-PC/Cholesterol Mixture

We describe the lyotropic liquid crystalline phase transitions in the lipid mixture dipalmitoil-PC/dilauroy-PC/cholesterol by 3D spin-1 lattice model. The formation of nanoscale domains with the characteristic size about 300 nm was studied in experiments on confocal fluorescence microscopy (CFM) (G. V. Feigenson and J. T. Buboltz, Biophys. J. 80, 2775 (2001)). The structure parameters of the lamellar vesicle in dipalmitoil-PC-rich phase, corresponding to these regions, are verified by numerical Monte Carlo simulations on the lattice. We point its superconductivity analogy properties at the region of phase stability for composition-dependent nanoscopic region.     

New method for measuring an optical property of a sample treated by FWA

In this article, a new method for measuring a total spectral radiance factor of a FWA‐treated sample illuminated by a specific standard illuminant is introduced. The method replaces an unstable real fluorescent standard by a bi‐spectral luminescent radiance factor data, which works as a virtual fluorescent standard (VFS) by knowing spectral intensity distributions of illuminations applied to the sample. The method utilizes two illuminations I₁ and I₂ whose relative spectral intensity distributions are different from each other and synthesizes a virtual illumination presenting the identical fluorescent spectral radiance factor to that presented by the standard illuminant with the VFS of the specific bi‐spectral luminescent radiance factor by linearly combining I₁ and I₂ with the suitable weighting factors. The applicability of the method is examined in principle by comparing ISO brightness and CIE whiteness index of fluorescent standard paper as a test sample obtained by this new method to the assigned values. © 2007 Wiley Periodicals, Inc.

Thick bone section preparation using a silicon-rubber-based sealant

A method has been developed, using a silicon-rubber-based sealant, which allows 2–3-mm-thick specimens to be maintained in a protected fluid environment for a number of months, without risk of dehydration. Following this, the specimen can be retrieved, stained, embedded and sectioned further. For example, 2-mm-thick sections of fixed unstained bone are easily examined by means of epi-illuminated polarized light and fluorescence microscopies using either conventional or confocal optics. The method could easily be extended to other tissues, for example brain tissue.

日光照射对荧光增白剂VBL顺-反异构现象影响的研究

用紫外光谱和荧光光谱法对日光照射荧光增白剂VBL溶液进行了研究。结果表明、随日光照射时间的延长，VBL溶液在432nm处荧光强度下降；而在267nm处有所增强，低浓度溶液对日光照射更加敏感。1mg／1在避光时测得吸光度为0.449，而在日光照射15分钟后，其吸光度下降至0.141，证明日光照射使VBL溶液中的顺式异构体增加。     

荧光染料用于涤纶织物染色的荧光性能研究

在实验条件下，染色织物的荧光反射率随荧光染料的浓度增加而增加，超过一定浓度后，有下降趋势；在pH=5左右，荧光反射率最高；荧光增白剂会提高染色织物的荧光反射率，在荧光黄2GFL中，当荧光增白剂的浓度由0.1％增加到5％时，荧光反射率由8．43增加至18．59，而对非荧光染料只有增艳的作用，不产生荧光。荧光染料染色织物的荧光反射率随着加入非荧光染料量的增加而减弱。
