The relative temperature can be used to link the mechanical properties of non-saline soil with those of saline soil.

相对温度的引入建立了盐渍土和非盐渍土力学性质的关系，从而可以用非盐渍土力学性质预测盐渍土的力学性质。

The relative temperature error of the measuring system is less than 2.13%. The repetition error of the system is within 1%.

分析得到测试系统的相对测温误差小于2.13%，重复性误差在1%以内。

So depending on the relative humidity and temperature, 100 or more water molecules diffuse out of the leaf for every molecule of carbon dioxide that diffuses in.

Heat indices combine temperature and relative humidity to indicate how hot the body feels.

The Met Office's "feels like temperature" takes into account expected air temperature, relative humidity and the strength of the wind at around 5 feet (1.5m) - the typical height of a person's face.
