tolerable limit

基本解釋

The hope is that the level of CO2 in the atmosphere can thus be kept below what is widely agreed to be the upper limit for a tolerable level of global warming, 450 parts per million.
人們希望，這樣一來(lái)，大氣中CO2的含量可以保持在百萬(wàn)分之450以下。人們普遍認(rèn)為，這就可以讓全球氣候變暖的程度處在可容忍的上限以下。
If the strain exceeds the tolerable limit, the Si-O-Si linkage can break easily at high temperature and lead to the creation of positive and negative charges on silicon and oxygen atoms, respectively.
如果張力超過(guò)耐受極限，硅氧烷鍵就很易在高溫下發(fā)生斷裂并在硅和氧原子上分別形成正負(fù)電荷。
