Under the conditions of wastewater volume 100 mL,activated carbon dosage 1.0 g,oxydol volume 1.0 mL,wastewater pH 3,microwave heating time 10 min and microwave radiation power 350 W,wastewater COD is decreased from 300 mg/L to 96.2 mg/L.
在100 mL水样中,活性炭用量为1.0 g、双氧水用量为1.0 mL、废水pH为3、微波加热时间为10 m in、辐射功率为350 W的条件下,可以使富马酸废水的COD从300 mg/L降至96.6 mg/L。
The experimental results show that β-naphthol is 3.6 g(0.025 mol),anhydrous alcohol is 30 mL,concentrated sulfuric acid is 7 mL,the microwave radiation power is 260 W,radiation time is 40 min,the yield of β-naphthyl ethyl ether exceed 71%.
2. It was once reported that Sr_2CeO_4 phosphor was synthesized by microwave radiation method. Here some improvements are made on it. The influence of microwave radiation power and heating time is discussed and the optimum condition to achieve superior Sr_2CeO_4 phosphor is confirmed.
Factors influencing properties of wooden activated carbon such as microwave radiation power,radiation time and flow rate of water vapor were systematically studied via orthogonal experiments. Optimum technology was obtained as follows:microwave radiation power 700 W,radiation time 6 min and flow rate of water vapor 3.09 mL/min.
Using the expression of the quadrupole and octapole radiation power, the multipole radiation power of a special binary star, PSR1913+16, are estimated. The results show that its whole power of quadrupole radiation is , which is coincident with the observed results, and that the expected whole power of octapole radiation is .
In addition, the acoustic radiation power and radiation efficiency of the beam is predicted, which provides theoretical basis for the acoustic radiation control of high-speed flexible beam- like components.
engine was studied. Taking a four-cylinder diesel engine as an example,acoustic response such as the entire engine's radiation power,the field point sound pressure level and the panel acoustic contribution,radiation efficiency etc.
A rise in the radiation power above an optimal magnitude decelerates the droplet growth.
The threshold radiation power densities necessary for sintering porous glasses of different compositions are obtained.
The morphology of the deposited patterns was investigated as a function of the laser radiation power and the number of scans.
Investigations are conducted into the process of crystallization of a bath with a ZrO2-8 mol % Y2O3 melt which is produced by local heating of ceramic by concentrated laser radiation and solidifies when the radiation power decreases by 20-30%.
The specific average radiation power in the visible range is 23 mW/cm2.
