Critics have blamed outsourcing for the company’s recent lapses: some twelve hundred suppliers design and manufacture parts for Boeing planes. “There were a number of issues that we had,” Larson said. “But we’re coming out of that. We can’t build airplanes fast enough.” He walked me over to a half-finished 777 that was about to have its wings attached. “I remember my very first fuselage join,” he said. “The mechanics drilled about eight hundred holes, then started inspecting the skin around them. I thought, This is going to take forever!” The wings have to be mated to the body with gaps of five- to ten-thousandths of an inch. Then they’re bolted on with just enough torque to flex and hold fast, even in the most severe turbulence. In Boeing’s stress tests, they can bend almost forty-five degrees and snap back, and withstand years of flexing without structural fatigue. “It’s not a piece of farm equipment,” Larson said. “It’s a life-support system. At thirty-five thousand feet, you can’t pull over.”。业内人士推荐哔哩哔哩作为进阶阅读
围绕减排路径，机构指出，1）能源体系的深度重构：利好风光核水、非电绿能氢能 、垃圾焚烧 、生物质、生物柴油替代化石能源直接消费等。2）终端部门的深度脱碳：①电气化、燃料电池车；②循环经济和资源回收降低原材料碳排放；③节能减碳技术，例如工业余热回收利用等；④CCUS碳捕集⑤碳服务业务：碳监测设备、碳核查服务。，这一点在17c 一起草官网中也有详细论述
