We report the discovery of two new Wolf-Rayet (WR) galaxies: Mrk 1039, and F08208+2816. Two broad WR bumps at 5808Å and 4650Å indicate the presence of WCE and WNL star population in all two sources. We also confirm the presence of WR features in Mrk 35, previously detected in a different position. The observed equivalent width of the WR bump at 4650Å and(More)
Sometimes, the traditional refrigeration system should operate even in cold seasons to control the temperature in data centers, control units of power stations. There are problems about operation economy and operating stability. The combination of refrigeration systems with heat pipes could provide a solution to weaken the problems. In this paper, a(More)
