单词 Standard Temperature and Pressure
释义

Standard Temperature and Pressure

原声例句
Crash Course 综合篇

STP means standard temperature and pressure, which according to the lords of chemistry is 0 degrees Celsius and 100,000 pascals or 100 kilopascals.

这个 STP 的意思是——标准温度和压力(简称为标准状况),在化学里它的意思是摄氏0度 和 10万帕斯卡 (或者说100千帕斯卡)。

Crash Course 综合篇

One last thing: remember that STP, or Standard Temperature and Pressure, is 0 degrees Celsius and 100 kilo-Pascals, but gas law equations are done in Kelvins, not degrees Celsius, so we'll call it 273.15 K and 100 kilo-Pascals.

最后一件事:请记住, STP,或标准温度和压力, 是 0 摄氏度和 100 千帕,但气体定律方程是用开尔文计算的, 而不是摄氏度, 所以我们称它为 273. 15 K 和 100 千帕.

标准状况 Standard conditions for temperature and pressure

(重定向自Standard Temperature and Pressure)

标准状况英语:standard temperature and pressure, STP标准温度与标准压力),简称「标况」。由于地表各处的温度、压力皆不同,即使是同一地点的温度压强也随测量时间不同而相异,因此为研究方便,制定出描述物质特征的标准状况:

历史上由巴黎制定的通行欧洲的旧制标准如下:

在化学和生物化学中另外还包括定义的观察反应物浓度,一般情况下为1mol/L(1 M)。在生物化学中只有质子例外(H)。限定pH为7,即10 mol/l H离子浓度用于准生理条件描述,肌体条件,细胞内部条件等。

Standard conditions for temperature and pressure 标准状况

(重定向自Standard Temperature and Pressure)

Standard conditions for temperature and pressure are standard sets of conditions for experimental measurements to be established to allow comparisons to be made between different sets of data. The most used standards are those of the International Union of Pure and Applied Chemistry (IUPAC) and the National Institute of Standards and Technology (NIST), although these are not universally accepted standards. Other organizations have established a variety of alternative definitions for their standard reference conditions.
