3、方程世界观人人都有,而哲学只有经过系统的学习的人才能掌握它。世界观是自发成的,是不系统的、不自觉的、缺乏严密的逻辑和理论论证,而哲学则是把自发的、零散的、朴素的世界观加以理论化和系统化,因而具有严密的逻辑和完整的理论体系。appearance of the weld appearance quality technical requirements of the project must not have a molten metal stream does not melt the base metal to weld, weld seam and heat-affected zone su
