问题：句子理解Theappliedartsarethusboundby 
The appli arts are thus bound by the laws of physics, which pertain to both the materials used in their making and the substances and things to be contained, supported, and sheltered. 其中的which是指the laws of physics吗？句子中的both分别指the materials和the substances吗？整句怎么翻译？特别是后面andThe appli arts are thus bound by the laws of physics, which pertain to both the materials used in their making and the substances and things to be contained, supported, and sheltered. 其中的which是指the laws of physics吗？句子中的both分别指the materials和the substances吗？整句怎么翻译？特别是后面and things……那句是什么意思？谢谢！！
回答：which是指thelawsofphysics。both分别指 ematerials和 esubstancesandthings注意两个the是属于both的东西。tobecontained,supported,andsheltered是用来描写thesubstancesandthings。whichpertainsto包括的意思,both紧接在后面,因此是说materials以及substancesandthings
