从仪器量测和自然界代表性物体所取得的温度变化记录是CRU论述的根据。
Lord Oxburgh and his colleagues were not concerned with whether CRU's scientific findings, which are based on records of temperature change from instruments and natural proxies, were correct.
在过去的一部分时间里，人们没有温度计测温，那些研究过程就使用具代表性的数据，比如树木的年轮来衡量。
For parts of the past where there were no thermometers to consult, such studies use proxy data, such as tree rings.
在碱溶性树脂中，以低分子量、窄分子量分布、高酸值、较低玻璃化温度的苯乙烯—丙烯酸共聚树脂（简称苯丙树脂）最具代表性。
Styrene-acrylic resin, a typical one among all alkali-soluble resins, has the criteria of low molecular weight, narrow molecular weight distribution, high acid value and low Tg.
