In addition, the feasibility and rationality to apply self-organization theory on traffic flow study are discussed, fractality and dissipation in traffic flow are studied preliminary 另外,對交通流的自組織的可能性進行了討論,對交通流的分形和耗散進行了初步的研究。
(5 ) aiming at irregularity of a real fracture surface or a real crack profile, applying griffith's criterion and fractal geometry, the real asymptotic expression at the crack tip is developed, and it is discovered that the fractality of the crack reduces the stress singularity at the crack tip (5)針對實際斷裂面或裂縫的不規(guī)則性,利用griffith能量平衡原理及分形幾何,推導了裂縫尖端實際應(yīng)力場和位移場的表達式,研究發(fā)現(xiàn),裂縫的分形性減小了裂縫尖端應(yīng)力的奇異性。
