We conducted a meta-analysis to evaluate current research that aims to map the neural correlates of two typical conditions of moral judgment: right-wrong moral judgments and decision-making in moral dilemmas. Utilizing the activation likelihood estimation (ALE) method, we conducted a meta-analysis using neuroimaging data obtained from twenty-one previous studies that measured responses in one or the other of these conditions. We found that across the studies (n = 400), distinct neural circuits correlated with a distinction in the type of moral question used as stimulus. For right-wrong moral judgments, the significantly active regions were identified in the right medial frontal gyrus, the bilateral anterior cingulates, the left inferior frontal gyrus, the right middle temporal gyrus, the left superior frontal gyrus and the left posterior cingulate.

In industrial production, such as steel industry, petroleum and chemical industry, mass of CO, as "waste", was not good used, for example: blast furnace gas, converter gas, yellow phosphorus tail gas, chemical tail gas, calcium carbide tail gas, garbage incineration gas, etc. Above gases are all rich in CO gas, can be used as secondary energy. PKU PIONEER developed a new VPSA-CO separation and purification technology. The new technology can recovery CO from secondary energy, and used it as chemical raw materials. By this way, it can greatly reduce CO2 emissions, save fossil energy, has good economic and social benefits.
