Seaweed extract-EClean was applied to treatment for eutrophication water. Quantative detection of nitrogen cycle bacteria showed that seaweed extract could improve the growth of ammonifying bacteria, nitrosobacteria and nitrobacteria in the treated water. There was also an increasing trend in the number of denitrifying bacteria in aerated treatment water, which showed that the seaweed extract could accelerate nitrogen cycle and the release of nitrogen from water.

利用国外引进的海藻提取物EClean制剂对富营养化水体进行处理试验，经过定量测定处理和对照水体中氮循环细菌数量的变化，得出EClean制剂能够促进水体的氨化细菌、亚硝化细菌、硝化细菌的生长，并维持了曝气条件下一定数量的反硝化细菌，通过此处理使得在同一反应器中、同一条件下完成硝化作用和反硝化作用成为可能，加速了水体的氮素循环，使水体总氮下降明显。

Before regeneration, 160 kg LAB product/kg catalyst can be obtained with over 98% of alkene conversion.

研究还表明，在Y型分子筛中引入Sr~(2+)后能增强分子筛对苯的吸附能力，在反应温度下使苯仍能维持活化吸附状态。

We use the single chip PIC18F452, as the center control circuit, and through the measurement of open circuit voltage and short circuit current to get the current system impedance, then force the apparent load impedance to match it to make the solar system working on maximum power point.
