熔点英文是melting point。
物质的熔点,即在一定压力下,纯物质的固态和液态呈平衡时的温度,也就是说在该压力和熔点温度下,纯物质呈固态的化学势和呈液态的化学势相等。
而对于分散度极大的纯物质固态体系(纳米体系)来说,表面部分不能忽视,其化学势则不仅是温度和压力的函数,而且还与固体颗粒的粒径有关,属于热力学一级相变过程。
例句:
1、液体保持在其熔点以上,直到需要蒸汽时才可以变回固体,释放其储存的能量。
The liquid is maintained above its melting point until steam is required at which point the liquid is allowed to turn back into a solid releasing its stored energy.
2、不需要蒸汽时,液体保持在熔点以上,需要蒸汽时液体才能变成固体,释放其储存的能量。
The liquid is maintained above its melting point until steam is required, at which point the liquid is allowed to turn back into a solid, releasing its stored energy.
3、结果显示,混配配合物与 DNA 作用时,使紫外吸收明显减色,荧光显著增强,DNA 熔点升高。
The compounds show absorption hypochromicity, fluorescence enhancement, DNA melting increasement when binding to CT·DNA.
4、氧化镁,熔点在2800摄氏度。
And magnesium oxide has a melting point of 2,800 degrees C.
5、它的熔点是204摄氏度。
It's got a melting point of 204 degrees Celsius.
