The correlation of multi-channel thermal infrared remote sensing information and its effect on retrieval of land surface temperature

The informational correlation among seven thermal infrared channels of MODIS is simulated. Results show that they have high correlation coefficient, which becomes one of the main obstacles to raise accuracy of LST retrieved by the remote sensing method. By means of principal component analysis we have proven 14 independent equations for retrieval of LST at most having five independent informative components, if seven bands are chosen for retrieval of LST, only three independent informative components exist. Therefore the property of retrieval of LST belongs to the underdetermined inverse problem. We cannot expect to get a stable and high accurate LST retrieved by various currently used remote sensing methods based on determined equations. From now on it is a main research topic to retrieve LST by underdetermined equations.

家兔背阔肌、后斜方肌、股薄肌和小腿三头肌动脉血管构筑初探

近年来,根据临床的需要和肌瓣、肌皮瓣移植手术的开展,有关肌肉血管应用解剖学的研究逐渐引起人们的重视．在用到临床之前必须有充足的动物实验作依据,但实验动物肌肉内的血管构筑情况目前仍是个空白．本文就是针对这一实际,对三十例经铅丹油造影剂灌注的家兔,进行大体解剖,并进行软Ｘ线造影,观察动脉血管在背阔肌、后斜方肌、股薄肌和小腿三头肌的分支类型,分布范围,同时测量动脉主干直径,从而确定家兔八块表层肌肉内动脉血管（营养血管）构筑的特征     

Cellulose beads modified by histidine: Preparation and adsorption behavior

Porous cellulose beads modified by histidine (PCBH) were prepared. The adsorption capacity of PCBH for divalent Mg(II), Cu(II), Pb(II) and Hg(II) ions were determined. The effects of the temperature, the initial pH value, the concentration of metal ion and PCBH ligand on the adsorption of Cu(II) Hg (II) were discussed. The adsorption process fitted to Freundlich adsorption isotherms for both metal ions. Adsorption rate constants were also found.
