For the enzyme extraction, with the ratio of enzyme/giant knotweed 1:500 at 50℃ for 90 min, the yield of resveratrol is two times more than that extracted by ethanol. For the microwave extraction with the ethanol content of 80%, the liquid ratio of 1:20, extracting by microwave for 60s at 510W, the yield of resveratrol is three times more than extracted by ethanol with enzymation 30 min by microwave for 10 s at 510 W.

酶法辅助提取白藜芦醇的适宜提取条件为:酶解温度为50℃、pH值为5.0、纤维素酶与虎杖粗粉质量配比为1:500、酶解时间为90 min,比传统乙醇提取法提取收率提高2倍;微波辅助醇提白藜芦醇的适宜提取条件为:以体积分数为80%的乙醇溶液为提取剂,料液质量比为1:20,在510 W功率下微波1.0 min,比传统乙醇提取法提取收率提高近3倍;利用酶微波结合提取白藜芦醇,酶解30 min, 510 W功率下微波10 s,提取收率提高3倍,缩短了提取时间,降低了生产成本。

If under ideal conditions, one electron-hole pair injected yields one blue photon and the quantum efficiency of the phosphor equals one, the numbers of electron-hole pair must equal to the numbers of white photons. So LW white LED radiation power output has to consume 1.51 W electric powers and the luminous flux efficiency limitation of electrical to optical conversion for the white LED is 197.8lm/W at above condition.

在理想情况下,注入一个电子-孔穴对产生一个蓝光光子,设荧光粉的量子效率为1,因此,注入的电子-孔穴对数亦等于白光光子数,进而计算出白光LED每辐射1W的光功率所需的电功率为1.51W,上述白光LED发光光谱对应的白光LED的电-光转换的理论极限流明效率为197.8lm/W。

At the rating power of 1 W , the lumen efficiency is close to 13 lm/ W.

在器件额定功率1W 附近,发光效率为13 lm/W 。
