各位老师好。

①Although no proof yet exists that electromagnetic fields generated by household appliances pose any threat to health, mounting scientific evidence has convinced many experts that there is cause for concern.

看起来划线部分是在修饰proof，为什么可以跨越谓语动词修饰呢？

②New techniques in thermal-scanning photography, a process that records radiation from surface areas, have made it possible to study in greater detail than ever before the effects of calefaction, or warming, of a river.

似乎划线部分原位置在study后面，为什么呢？

这两个句子是一种类型吗？这种现象的学术名称被称作什么？我想更多地了解却找不到更多的解释。谢谢各位老师的解答！
