Natural gas is a promising alternative fuel for the internal combustion engine,and natural gas engine has become an efficient and feasible measure to deal with the energy shortage and climate *** the laminar flame characteristics are the foundation of the turbulent flame,the laminar flame characteristics of natural gas have a significant impact on the combustion status and efficiency of the engine.A visual constant volume bomb was used to study the influence of the gas components,different excess air coefficient(λ),and initial conditions on the laminar combustion characteristics of natural *** experimental results showed that when the initial pressure and temperature were 0.1 MPa and 300 K respectively,compared to propane,ethane had a remarkable influence on the equivalent-combustion laminar-combustion-speed,with an average increase of approximately 5.1%for every 2.5%increase in the ethane *** laminar combustion velocity of the natural gas under different excess air coefficients had a maximum value at aboutλ=1.0,and the Markstein length of the flame decreased with the increase of theλ.The increase in the initial pressure of the mixture resulted in a decrease in the equivalent-combustion laminar-combustion-speed of the flame,a significant decrease in the Markstein *** increase of the initial temperature of the mixture led to a rapid increase of the equivalent-combustion laminar-combustion-speed,but the effect on the flame Markstein length was not dominant.

《周易》在古代被称为群经之首、大道之源,其思维范式和思想内容不但是儒家思想体系产生、发展的形上根据,而且与部分诸子学说的思想架构也有着千丝万缕的联系,在先秦思想史和文化史上占有重要位置。比较《系辞传》和《墨子·节用篇》语言文字、逻辑理路的异同,可见《易传》《墨子》间的内在关联;梳理《周易》古经的思想元素与《墨子》思想内容的内在联系,可见《周易》古经在墨家思想体系形成中的作用,进而管窥战国时期的儒、墨关系。
