Table 2.Chemical composition of water in the study area | Show Table DownLoad:CSV 由水样Piper三线图(Piper, 1944)可知(图2),区内地热水中阳离子均以Ca2+占主导地位,其次含有一定量的Na+、Mg2+和K+离子,其中WQ02和ZK02样品中Na+含量较高,达到22.51～26.00 mg/L,显著高于其它样品。地热水中阴离子均以HC...
If we wish to write an equation for the chemical reaction between the elements phosphorus and oxygen, we begin with the formulae for the molecules of phosphorus and oxygen. P4 (s) + O2 (g)---> [※s = solid , g = gas.] Again, we state the formulae of the molecules which reac...
going to sea as an officer, [the seafaring background] reminds me that when we're shoreside, we can take for granted what the seafarers are up against, and what they're doing to push the steel," says Noonan, who has been named the Connecticut Maritime Association's Commodore for 2017....
We have studied the molecular level cavitation mechanisms and bubble growth kinetics in soft gelatin hydrogel and water. The apparent difference in cavitation threshold pressure between that generates in pure water and that in gelatin hydrogel is conside
