The results of xrd analysis demonstrated that the perovskite pmn - pt was rather stable in a large temperature scale 热处理实验表明，合成的pmn - pt钙钛矿相在很宽的温度范围内是稳定的。
1701 anders celsius , swedish astronomer who devised the centigrade temperature scale in 1742 , was born at uppsala 瑞典天文学家安德斯?摄尔修斯诞生于乌普萨拉。他于1724年发明摄氏温度计。
Because of the way earlier temperature scales were defined , it remains common practice to express a temperature in terms of its difference from 273 . 15 k , the ice point 基于早期温标的定义，温度一般以其与273 . 15k (冰点)的差来表达。
A direct display occurs , for example , by means of a capillary tube closed system , that sits on the temperature scale machine thermometer , clinical thermometer etc . 直接显示的例子是由一个刻有刻度指数的毛细管封闭系统，比如机械温度计，体温计等等。
The change in volume of a defined amount of measuring liquid , usually alcohol , is displayed on a temperature scale directly or indirectly via various methods 已定义的一定测量值的液体通常为酒精的体积变化，通过各种方法直接或者间接地在温度计上显示出来。
Kelvin is the unit for the absolute temperature scale . one kelvin is equal to one degree celsius . however , the absolute temperature scale is shifted by 273 绝对温度是科学界最通用的温度单位，只要将它减去273 ，便可转化为摄氏度，例如绝对温度300度，相等于摄氏27度。
Chapter three focuses attentions on the interaction between discrete heat sources ( dhss ) indoors and their effects on iae . in order to identify the discrete heat sources of different strength , type and size , a combined temperature scale is first developed 如何描述室内大小、类型与强度不同的离散热源之间的相互作用及其对室内空气环境的影响即是第三章的主要内容。
The first international temperature scale was adopted in 1927 , revised in 1948 as ipts - 48 , revised again in 1968 as ipts - 68 , and again more recently in 1990 as its - 90 . officially scl adopted the its - 90 from 1 january 1990 首个国际温标( internationaltemperaturescale )于一九二七年被采用，并于一九四八年被修订为ipts - 48及于一九六八年再被修订为ipts - 68 ，最近更于一九九零年被修订为its - 90 。
The precise measurement of thermodynamic temperatures , for example with a gas thermometer , is very difficult . practical temperature scales were therefore introduced to make use of instruments such as platinum resistance thermometers which are much easier to use and give much higher precision measurements 要准确测量热力学温度(如使用气体温度计来进行测量)是十分困难的，因此利用铂电阻温度计等作测量器的实用温标便被采用，令使用更为容易及测量更为精确。
