相当于 a solid changes into a liquid at which,也就是at which,相当于at the temperature在某个温度,用介词at,比如Water freezes at the temperature of 0 degrees Celsius. 水在摄氏零度结冰。祝同学学习进步~<校友会师生线下活动限额招募,礼品丰厚,感兴趣的同学请戳这里报名哟> http://hjvote.yeshj.com/...
At the same time, the trends of the changes depended on the genesis and initial properties of the soils. The composition of the organic substances in the lysimetric water was related to the soil nature, and, during 20 years, it essentially did not change....

Additionally, we find that the drop behaviour is very sensitive to small changes in ϕ, consistent with the transition to shear thickening in rheological measurements [Fig. 1b]. Fig. 3: State diagram of colloidal drop impact. ϕ − u0 state diagram summarizing impact regimes; ...
asolid to a liquid, at 0 Celsius. We also know that water boils, or changes feom a liquid to a gas, at 100 Celsius. Research the melting and boiling points of five other substances. How do these melting and boiling points compare to those of water. 固体对液体,在0摄氏。 我们也知道水...
The NMR spectra of the R385H mutant displayed shifted peaks and changes in intensity relative to wild-type MEC-2 (Extended Data Fig. 4l–o), suggesting that the mutation affects MEC-2 homotypic interactions. We found, however, that the R385H mutation did not alter the phase separation of...
