In this paper, a novel fluorescence probe based on Rhodamine(RB), which can be used in the quick detection of Cu2+ in environment, was synthesized. It was found that the addition of Cu ions led to a significantly enhanced fluorescence, while other common metal ions such as Na+, K +,Mg2+,Ca2+,Mn2+,Co2+,Ni2+,Ag+,Ba2+,Zn2+,Fe3+andFe2+...

This paper introduces the retrofit of the condenser of a 300MW high backpressure heating turbine. According to the test data of high and low backpressure situation, we calculated the operation indexes of the condenser at these situation. The condenser terminal temperature difference is both small at...

A large number of thermal recovery wells casing was damaged during the early development of Du 84. Casing damage thermal production wells amounted to 214 by the end of 2002, accounting for 66.7% of the production wells. The casing damage had affected the normal production of these thermal wells. Thus...

Landscape pattern change will lead to flows and changes of energy, material and nutrients between different land units, and cause sectional ecological processes and functional changes.
