Urban climate change: A comprehensive ecological analysis of the thermo-effects of major Chinese cities

Using 89 major Chinese cities which comprise the case study area, this article computed the urban thermo-effect of summer in the 1990s and 2000s compared to that in the 1950s, using the database of highest monthly temperatures recorded by national weather stations from 1951 to 2007.

A zirconia near-blackbody radiation source, 2500 K in air

AbstractA near-blackbody radiation source was designed for operating in an oxidizing atmosphere up to 2500 K. As a small zirconia furnace, the radiation source has a blackbody cavity, provided by a lateral hole formed on an yttria-stabilized zirconia tube.
