Thermal resistance value measured between resistive layer and outer side of the resistor.It is the thermal resistance of the component:0.11 °C/W.
在电阻的电阻层与其外层测得的热阻值就是元件的热电阻：0.11℃/W.
Thermal resistance value measured between outer side of the resistor and room temperature.It is the thermal resistance of the heatsink,depending on the heatsink itself (type,shape) and the quality of the fastening device.
在电阻的外层与室温测得的热阻值就是吸热器的热阻,这要取决于吸热器自身的形式或形状以及固定装置的质量.
翻译说明：
我的理解,这里的质量指的是物体的质量重,可以译为重量.因为一个物体的重量（质量）影响其热阻.还有,所以‘℃/W’是指‘摄氏度/重量’.
