Measurements of ultraviolet (UV) radiation at 38 stations from Chinese Ecosystem Research Network during 2006–2012 were used for reconstructing the historical UV levels in China for the first time. UV models were introduced by analyzing the dependence of UV irradiation on clearness index (Kt)...

Observations of UV radiation (290–400 nm) at Yanting, China (31°16′ N, 105°27′ E and 420 m above sea level) from 2005 to 2012 were used for investigating UV variability and its relationship with global solar radiation in Southwest China. Daily UV/G ratios generally increased from 3.7%...

Measurements of UV (ultraviolet) and global solar radiation in Central China during 2006–2012 were first reported to investigate the UV radiation variability in different time scales and its UV fraction under different sky conditions. Both UV irradiation and UV fraction showed similar features...

The basic chemical composition of coal and ash is an important but insufficient characteristic for the reliable explanation of coal properties. The modes of occurrence of the elements, their origin and concentration in coal, as well as their behavior during the coalification process, are also...

Phase change material (PCM), has been widely researched in many previous works, shows a good potential for thermal energy storage. The present paper investigated the mesoscopic morphologies and evolution mechanism of microencapsulated phase change materials (MEPCMs) using dissipative particle...

Oxygen-enriched combustion of diesel engine can reduce smoke emission and improve thermal efficiency, but also lead to the increase of NO emission. In this research, experiments were conducted on a turbo-charged direct injection diesel engine under the two conditions of 2000 rpm and 180 Nm...

The traditional ORC (organic Rankine cycle) based geoplant results in a higher irreversible loss. The PDORC (parallel double-evaporator organic Rankine cycle) was put forward to decrease the system irreversibility and enhance the power output. The TEIC (thermal efficiency intensification...
