全息光栅扫描器在光学扫描装置中的应用的重要性在不断增加。本文描述一种全息扫描法,其中反射体积全息图记录在铬盐明胶板上,并以多边形的形式安置在一个圆筒的周围。这种扫描器以反射方式工作,便于做成紧凑的折叠型以及在布喇格条件下只有一级衍射。F是点源P与全息图平面之间的距离,圆筒的半径为r。旋转这个全息图,就会使无畸变的再现斑点沿一曲线轨迹扫描。在许多应用中都希望有一个平的扫描面。利用计算机再现全息图产生的非球面波前完成了场曲率校正工作。全息图跟平场平面间

这篇短评是一篇以成型的软钎料金属丝,成功地密封可拆卸连接方面的报导。介绍在超流体中,甚至在反复的热循环之后的超真空密封。对于在液氦温度下工作的可拆卸真空密封,铟丝已经是最普遍的密封材料。但与铟丝相比,软钎料密封填料成本较低,而且拆卸时,没有令人烦恼的附着在接合表面上的问题。

Although the transcription factor, nudear factor-κB （NF-κB） is known to regulate cell death and survival, its precise role in cell death within the central nervous system （CNS） remains unknown. We previously reported that mice with a homozygous deficiency for NF-κBp50 spon- taneously developed optic neuropathy. We examined the expression and activation of pro-apoptotic factor（s） that mediate optic neuropathy in p50-/- mice. Recombination activating gene 1 （Ragl） is known to regulate the recombination of immunoglobulin V（D）J.
