objective to study mri diagnostic value on multiple sclerosis.methods mri examination data of 31 patients with multiple sclerosis were analysised retrospectively.results total 184 lesions were detectived in 31 patients.most lesions were located on white watter area beside the lateral ventricle,and a few lesions were located on the spinal cord,cerebellum,brain stem and corpus callosum.the shape of lesion can be circle or ellipse.the lesion showed as slightly long t1 and long t2 signal.the acute stage lesions can have enhancement.conclusions ms have characteristic findings on mri image.mri can show the patholoic changes,and provide strong evidence for clinic diagnosis of multiple sclerosis.

摘 要］目的：探讨多发性硬化（muliplle sclerosis，ms）的mri特征表现及其诊断价值。方法：回顾分析31例临床诊断为ms患者的mri检查资料。结果：31例共发现病灶184个，病灶于侧脑室旁白质区、半卵圆中心及皮层下区最多见，其次见于脊髓小脑、脑干及胼胝体，部分可见视神经受累，病灶呈卵圆形或圆形稍长t1、长t2信号，矢状位像见病灶与侧脑室垂直，急性病灶增强扫描有的可呈结节状、环状或斑点状强化。结论：在mri图像上ms有特征性表现，mri能反应ms病理变化，为临床诊断ms提供可靠依据。

A new wavemeter with cathode-ray for decimeter and centimeter waves is proposed, utilizing special deflections of cathode ray in a rapidly alternating field. When the wavelength of the deflecting field is short enough, the deflections can be made to have maximum and zero sensitivities or phase-shifts by adjusting the anode voltage.

The strength deck,botom,and side shell of a ship act as a box girder in resisting bending and other loads imposed on the structure .the weather deck, bottom ,and side shell also form a fight envelope to withstand the sea locally, and to provide the buoyancy which keeps the ship afloat.

船舶在抵抗弯曲和其他强加在结构上的负荷时，强力甲板、船底和船侧构成一根箱形梁。露天甲板、船底和船侧也构成一个框架局部承受海水压力，并且提供使船舶浮在水面的浮力。

HRP was coupled with the fluorochrome FITC and encapsulated with liposome . pEGFP-N1 plasmid (expressing green fluorescent protein) with encapsulation in commercially available liposome was prepared. The eyes were enucleated 1, 4 and 8 weeks after zonule rupture and anterior segments comprising lenses were incubated in medium containing one of these components. Cryo-sections were made and translocation of fluorescent macromolecule from the medium into the lens and green fluorescent protein expression in the epithelium were observed by fluorescent microscopy.
