The sensitivity and specificity of far-infrared thermography in the diagnosis of lumbar disc herniation were evaluated. Compared with the normal, the thermogram of twenty-three cases on low back with LDH changed. They can be divided into four thermal patterns that is shuttle-liking (8 cases), discontinued in the middle line (6 cases), large regional (5 cases) and nonregular (4 cases) pattern. The temperature of abnormal sides is lower than the counterpart in most cases (nineteen of twenty-three). The thermography diagnosed LDH with sensitivity 90.48% and specificity 66.68%.

结果 F-IRT显示：23例LDH患者腰骶部热形态改变为四种形式：梭形，热区向一侧偏歪或呈角状突起（8例）；夸中线热区不连贯（6例）；骶髂骨上缘呈大片高温热区（5例）；不规则形态（4例），患侧下肢较相对应的对侧胶体的温度，至少有一个患侧部位出现温度下降的有19例(82.61%)，综合CT与F-IRT结果分析：F-IRT诊断腰椎间盘侧后突的灵敏度为90.48%，特异度为66.68%。

Recently, a nearly E-W-striking, over 10 km long albitite zone has been recognized for the first time in the Lower Silurian Meiziya Formation in a Lower Paleozoic lead-zinc ore deposit concentration area of the Xunyang basin, South Qinling. It shows a conformable contact and gradational relationships with the country rocks and has thick-bedded and massive, banded, brecciated structures and fine and very fine equigranular and intraclastic textures. It is chemically characterized by enrichment in SiO2, Al2O3 and Na2O and is rich in the trace elements Fe and Mn and poor in the trace elements Co, Ni and Cu. Its ∑REE, LREE and HREE are lower than those of the country rocks and exhibit pronounced Eu depletion.

Using a nonperturbative scattering theory developed by Guo,Aberg and Crasemann the angular distributions of electrons in above threshold ionization of Krypton atoms irridated by a bichromatic phase-controlled laser field of linear polarizations is studied. The bichromatic phase-controlled laser field is composed of a sequence of identical one-cycle laser pulses.

It is found from experiment that when pumped by skew light along the fibre's axis, both transverse electric wave and transverse magnetic wave exist in WGM lasing emission simultaneitly. With the increase of refractive index of cladding dye solution, the wavelength spacing between TE and TM waves of which the radial mode number and angular mode number are the same value decreases, and the central lasing wavelength of WGM bluely shifts to short wavelength direction.

实验发现，在抽运光以偏斜光线方式沿光纤的近轴向抽运时，回音壁模式的光纤激光辐射中，既存在光电矢量和光纤径向垂直的横电波，也存在光电矢量和光纤径向平行的横磁波；随增益包层染料溶液折射率的增加，径向模式数和角模式数相同的TE波和TM波之间的波长差单调减小，回音壁模式激光辐射的中心波长向短波方向移动，辐射的波长范围变窄。

But afore-mentioned case of illness are the fastest the 6 H after art is the slowest 20 H appears cannot sit quietly, companion breaks up to have quiver on eyeball, brothers Xu is moved, slant first, neck rigidity, flesh is clonic, present opisthotonos individually, but nonexistent pathology is reflexed (Ba Bin this base electronegative).
