比较不同工艺条件制备的NiO材料，发现反应溶液pH值等于11.7、热处理温度500℃以及热处理时间8h的NiO电极材料比容量最高，在1mol/L Na_2SO_4溶液、-0.2～+0.8V扫描电位内，1mV/s扫描速率下达到38.2F/g。

With LTSs, peak pressures at the buttock were smaller than those without LTSs for all subjects, but symmetry index and center of pressure displacement did not change significantly.

有躯干侧支撑时，所有受试者的臀部最高压力值都降低，但是压力中心位移并没有明显改变。

The results show that the anaerobic digestion can fit for the characteristics of anaerobic fermentation of vegetable wastes. Among inoculums concentrations of 20%, 30% and 50%, the contents of VFA, NH4+-N and pH value for the 30% inoculums concentration were normal, and the total biogas content and the maximum CH4 content were 7790.81 mL and 42.514%, respectively, which were obviously higher than those of other two treatments and control.

结果表明，蔬菜废弃物用厌氧发酵工艺处理是可行的；在试验采用的20%，30%，50%三个水平的接种物浓度中，接种物浓度为30%的实验组的挥发酸含量、氨态氮含量以及pH值都在正常范围内，总产气量和沼气中最高甲烷含量分别为 7790.81 mL和 42.814%，明显高于其他两组及空白组实验。

Results showed that the polyphenoloxidase was activated when the high pressure treatment on the pear juice was carried out under the temperature 50 ℃,the dwell time 10 min,the pH5 and the pressure between 200～300 MPa.

实验结果分析表明：在处理温度为50℃、保压时间为10min和梨汁pH值为5的条件下，200～300MPa处理梨汁时多酚氧化酶被激活，活性表现最高；500MPa时酶的活性下降到75.3%。协同温度为30℃处理梨汁时，酶的活性反而增大；30℃以后，酶活性随温度升高而迅速降低；有效协同高压处理的温度为40℃。
