摘要
抚顺××厂３＃万ｍ３储油罐自１９９０年以来，罐体基础持续产生不均匀沉降。围绕该储油罐，通过高压定喷施工工艺，构筑定喷桩，地下防渗连续墙，在墙体内侧对罐体地基进行冲积层及基岩的直、斜孔注浆，用水泥浆液充填、胶结地基中的空化、裂隙，提高了地基强度，对减缓罐体的不均匀沉降，取得了显著成效。
Determination of trace tellurium in pyrite and geo chemical samples by hydride non dispersive AFS was studied. The samples were decomposed with HNO 3 HCl HClO 4, Te(Ⅵ) was reduced to Te(Ⅳ) by using the concentrate hydrochloric acid, then, the hydride (TeΗ 2) was formed by adding KBH 4, and it was determined by 1001C Atomic Flurescence Spectrophotometry. The detection limit of Te was 0.18 ug/g and the relative standard deviation was 6.8%.The method was simple, rapid, accurate and low cost. It was applicable to analysis of large amount of Geo chemical samples.
