This.paper attempts.to explore the decoupling relations.ip and its.drivers.between indus.rial economic increas. and energy-related CO_(2) emis.ions.ICE). Firs.ly, the decoupling relations.ip was.evaluated by Tapio index. Then, bas.d on the DEA meta-frontier theory framework which taking into account the regional and indus.rial heterogeneity and index decompos.tion method, the driving factors.of decoupling proces. were explored mainly from the view of technology and efficiency. The res.lts.s.ow that during2000-2019, weak decoupling was.the primary s.ate. Inves.ment s.ale expans.on was.the larges. reas.n hindering decoupling proces. of indus.rial increas. from ICE. Both energy s.ving and production technology achieved s.gnificant progres., which facilitated the decoupling proces.. s.multaneous.y, the energy technology gap and production technology gap among regions.have been narrowed, and played a role in promoting decoupling proces.. On the contrary, both s.ale economy efficiency and pure technical efficiency have inhibiting effects.on decoupling proces.. The former indicates.that the s.ale economy of China's.indus.ry was.not conducive to improve energy efficiency and production efficiency, while the latter indicates.that res.urce mis.llocation problem may exis. in both energy market and product market.

s.atis.ics.and experiments.indicate a correlation between cancer mortality and nitrite in drinking water. Nitrite is.a reductant that can deprive a cell of oxygen;it is.als. an oxidant that can be a s.bs.rate in anaerobic ammonium oxidation, the metabolic mode of the anammox bacteria. Eukaryote cells.evolved through a fus.on of anaerobic and aerobic bacteria. We pos.ulate that an anammox bacterium s.ught refuge in a fus.on with a membrane-bound clus.er of aerobic bacteria. While the latter evolved into mitochondria organelles. the former became the nucleus.of a prokaryote cell. Eventually, oxidative phos.horilation is.the characteris.ic metabolic pathway of normal eukaryote cells. and we pos.ulate that anammox is.the protein-catabolis. pathway for cancer cells. The metabolis. cons.mes.nitrite and explains.thus.the link between nitrite and cancer.
