When through conventional Ways at 4 hours, the leaching rate of roasted sample and gold bearing oxide ore are only 49. 1% and 79. 9% respectively: when utilizing oxidant GY, they reach 88. 1% and 87. 4%, rising 39% and 7. 5% respectively.

当浸出时间为4小时，常规充气时，金精矿焙烧样和含金氧化矿的浸出率分别只有49.1%和79.9%；当采用供氧体GY时，其浸出率分别达到88.1%和87.4%，分别提高39%和7.5%。

A method for the analysis of zinc oxide phase content in sulfide ore was studied. On the basis of the characteristics of each phase component, the sulfide ore sample was leached twice with NaOH and acetic acid-ascorbic acid, respectively, so that the oxide mineral and zinc oxide were dissolved completely. The leaching rate of zinc oxide phase was up to 98 Vo. Moreover, the dissolution of zinc sulfide phase was effectively inhibited, solving the problems of selective leaching and determination for zinc oxide.

研究了硫化矿中氧化锌相含量的分析方法，根据硫化矿中各物相组分特点，提出了用氢氧化钠溶液和乙酸－抗坏血酸溶液二次浸取硫化矿，使锌氧化矿、氧化锌充分溶解，氧化锌相的浸取率达到98%以上，同时有效地抑制了硫化锌相的溶解，较好地解决了氧化锌相选择溶解测定的问题。

It was validated experimentally. Under the optimized operating condition for transparent samples, the changing rate of the phase difference curve near the resonance angle was reduced with the enhancement of the sample's attenuation coefficient. This degrades sensitivity of phase detection of the SPR based sensors.

结果表明：针对透明介质优化设计的SPR结构用于测量吸收介质时，相位差曲线在共振角附近的变化率随样品衰减系数的增大而减小，导致SPR相位型传感器的灵敏度退化。

It is indicated that only a single resonance peak appears in the amplitude versus frequency curve without spurious resonance peaks during the procedure. The direct actuation enables to improve the tuning accuracy, weaken the possible sample damage by the tip, and enhance the atomic force microscope bandwidth and imaging rate.

研究表明，采用压电探针的直接激振方法在探针振动的幅频曲线中仅有单一谐振峰，可以避免在压电陶瓷管激振方法下由液体振动造成的寄生谐振峰，因此使用压电探针不仅提高了探针振动频率的控制精度，而且减小了针尖对样品的损坏，还提高了仪器的带宽和成像速度。

A significant difference was found by independent sample t-test (p.05). Conclusions: The better survival rate was found for patients with intensivist care in this study; therefore, it proved that the quality of care can be increased practically with intensivist care in surgical intensive care units.
