To study the relation between the water-volume exchange rates and the salt-exchange rates of the Akashi and the Naruto Straits in the Seto Inland Sea of Japan, we use an observed salt distribution near the straits, the calculated Eulerian velocity of the Mcurrent and the calculated location of...
The water and salt balances of the permanent North Basin and ephemeral South Basin during the experiment were evaluated using a combination of hydrometric techniques and trends for salinity and the stable isotopes of water. Filling of the basins (with freshwater from the River Murray) decreased ...

根据“because salt water is heavier. The heavier salt water stays at the bottom of the glass and the lighter coloured water at the top.”可知,盐使无色水变得更重。故选C。(3)题详解: 推理判断题。根据标题“An experiment (实验) you can try at home”并通读全文可知,本文介绍了可以在家做的一...
可知,空处应填 food colouring。2.根据表格中 HOW IT WORKS 下的“because salt water is heavier”可知,盐使无色的水变得更重。3.根据表格内容特别是标题中的“experiment”可知,这则阅读材料主要介绍了一个科学小实验,因此我们能在杂志的“Amazing Science”版块找到。
The network analyzer and open-ended coaxial-line probe technology were used to study the influence of addition of water (0 -20%) and salt (0 -4%) on the dielectric properties of minced pork loin within the frequency range from 10 to 4500MHz at 25 ℃. The results showed that the relati...
