  2. We also investigated the pathological changes of mouse liver, thymus and cerebrum cortex challenged by so2 inhalation by in vivo tests. we studied the apoptotic induction on mouse spleen cells and cytotoxicity of human embryo lung fibroblasts of so2 derivatives by in vitro tests. in vivo tests of sulfur dioxide inhalation showed : ( 1 ) effects on mouse lung of so2 challenge : we found no significant apoptotic changes induced by so2 inhalation but obvious pathological changes of lung with vacuolating of osmiophilic multilamellar bodies which maybe related with the decrease of surfacant and decrease of microvillus of type ii alveolar cells ; we also found thickening of part of basement lamina between type i alveolar cells and capillary endothelium cells which may inhibit the dispersion of oxygen and contribute to lung dysfunction

    二氧化硫熏氣染毒的體內實驗結果表明，在本次實驗的濃度范圍內（ 56mg m ~ 3 、 112mg m ~ 3 、 168mg m ~ 3低、中、高三個濃度） ： （ 1 ）通過透射電鏡、 dna凝膠電泳分析和流式細胞分析發現二氧化硫吸入染毒一周對小鼠肺臟沒有明顯的凋亡誘導作用，但通過透射電鏡觀察發現二氧化硫可引起肺臟明顯的超微結構改變，引起型肺泡上皮細胞板層體空泡化，微絨毛減少，線粒體緻密化或腫脹變性；肺泡血管內皮細胞和型肺泡上皮細胞之間基膜增厚，使氧氣彌散功能出現障礙，從而降低肺功能。
  3. For the tectonic coal ， the properties of higher porosity and lower permeability make it capable of keeping higher gas pressure ； both of the “ isolating action ” and “ gas - cushion action ” cut down the resistance against outburst ； the specifity of high - defomed - extent makes desorption ， escape and flowing quickly become possible ； the existing of weak - seam or “ thoroughfare - seam ” create suitable conditions for the initial erupting and continued developing of coal and gas outburst. on the whole ， it is the synhesis action of all factors ， which leads to outbursts. the existing of tectonic coal with certain thickess is the essential condition of coal and gas outbursts ， but not the sufficient condition

    高空隙率、低透氣性使構造煤能夠保持較高的瓦斯壓力；破碎性、 「隔離」作用及「氣墊」作用，使構造煤抵禦外力作用的能力大大降低；構造煤變形幅度大的特性，為瓦斯的迅速解吸、放散和快速流動創造了條件；構造煤薄弱分層或「通道層」的存在，則為煤與瓦斯突出的初始激發和持續發展奠定了基礎；上述因素的共同作用，影響和制約了煤與瓦斯突出的強度和分佈.盡管如此，一定厚度的構造煤的存在只是發生煤與瓦斯突出的必要條件和有利條件，而非充分條件
  4. The investigation presents a new method of dipping sic kiln furniture into 2 saturable solution or into the saturable solution of ca3 ( po4 ) 2 and a1po4 in order to beneficial to its crystalline structure change and its properties, to make it packed and decrease its porosity. it can also hinder the diffusion of oxygen so as to decrease the oxidation rate and lengthen the useful life. the mechanism of dipping two kinds of phosphate saturable solution were studied and proved by the results of scanning electron microscope
