The microstructural nomograph of these Al-Si alloys is constructed to provide for the selection of optimum addition of Sr or Sb in production practice Experimental results indicate a threshold of Sr content in Al-Si alloy modification, over it, the structure of Al-Si alloy may be completely modified even at quite slow cooling rate down to 4.5℃/min.

Due to the increasingly deep concerns about the cytotoxicity of stannous octoate, which is the most widely used catalyst for synthesizing polyesters derived from lactides (L-LA, D, L-LA, GA) via ring opening polymerization, a lot of new metal complexes of relatively low toxicity including Schiff base–Al complexes, Red-Al were developed and used to initiate the living, stereo-specific, and/or stereo-selective ROP of lactides.

Results show that protons are liberated by dehydration or dehydroxylation after calcination at 500℃. These protons disrupt the silicon-oxygen-aluminium bridges where there are Al substitutions in the tetrahedral sheet of the montmorillonite. Some of silicon-oxygen and aluminum-oxygen tetrahedral invert to react with the pillaring agents and yield covalent bonds which firmly fix the pillars to the host clay. The Al-MMT are thermally and hydrothermally stable up to 700℃.

While the tissue spaces surrounding a few blood vessels wasAl and Fg positive,no Al or Fg positive cells were observed.In antemortem injurygroup,diffuse subarachnoid hemorrhage,cerebral edema,swelling or pyknotic neu-rons could be observed.The axons showed irregular swelling and disconnection at1～3h,marked swelling and disconnection at 6h,and retraction ball at 15h whichwas more remarkable at 24h after injury.The space between myelin sheaths andaxons was increased at 3～6h after injury.Tortuous and wavelike myelin sheathswhich adhered on axons incompletely,or even peeled off could be found from 15hto 24h after injury.Perinuclear lysis of Nissl bodies began at 24h after injury.Thenumber of GFAP positive cells in cerebrum and brain-stem increased significantlyfollowed by decrease,and then increased again,but the time courses of the changesin different areas of brain were not same.Al and Fg positive neural cells,mainlysurrounded blood vessels,with diffuse or peripherally distributed positive matter incytoplasm could be observed at 0.5h after injury.The number of Al or Fg positivecells and the intensity of immunoreaction increased with the time of injury.The areaof SYN positivity in medulla oblongata and pons decreased notably 3～6h afterinjury,then return to normal levels and continued to 24h after injury.
