Application of the SEM mold technique to researching the pore texture of oil sandstone with a low permeability can upgrade the research from by 2 D analysing on thin sections to by 3 D observing in a mold sample,thereby greatly improving the prcdision and reliability of the reseach results. However,the key to reach the goal,as shown in the experimental report,is how to prepare the qualified mold samples.

安山巖中的黃銅礦是廬江中生代陸相火山熱液型銅礦床的原生礦，礦石中主要伴生黃鐵礦及少量斑銅礦、赤鐵礦和褐鐵礦。物相分析結(jié)果，黃銅礦的粒度很細(xì)，，只有細(xì)磨才能單體解離；它在礦石中分布極不均勻，且與脈石礦物接觸疏松，適于粗磨拋尾。物性分析結(jié)果，黃銅礦在４００～５３０℃、斑銅礦在４５０～６００℃、黃鐵礦在５００～６８０℃氧化分解。實(shí)驗(yàn)研究表明，礦石經(jīng)磨碎磁選，大部分的粗粒級的鐵礦物能夠回收；粗磨拋尾可獲得銅、硫的粗精礦；然后再經(jīng)硫酸化焙燒、酸浸、過濾、提純、濃縮結(jié)晶可制得工業(yè)級硫酸銅。浸渣做煉鐵原料，黃鉀鐵礬做Ｆｅ２Ｏ３顏料，有時還可回收金、銀。

PZT powders were made using oxide sintering technique. X-ray diffraction (XRD) peaks of powders were monitored and showed that PZT was in crystallization phase of pure square with Zr/Ti of 52:48. The pattern of the PZT powder was observed with SEMI the mold technique of PVDF was analyzed by TG-DTA. Six sorts of PZT/PVDF composites were obtained with different PZT volume ratio by compression moulding/sintering technique. Tests of dielectric and piezoelectric showed that electric parameter accretion with PZT content increased nonlinearly, when the volume content of PZT exceeds 70%, dielectric constantε and piezoeclectric constant increased rapidly, when it reached 90% the electric parameters were almost the same as the pure PZT's.
