Figure with double logarithm is adopted , hi this way all data points distribute around a straight line with non - zero slope . in a figure with double logarithm coordinates , straight line means the scale invariance of relative fluctuations , i . e . no scale seems special 双对数坐标系里的直线意味着相对起伏变量的标度不变性,即:在任何标d硕士学住论文q一少” r厂sumis度上都没有什么特征使这个标度显得特别。
The concept of the longitudinal strength of ship hulls has changed and advanced greatly as the study on the failure mechanism of the hull is getting deep . by taking account the failure modes of yielding , buckling and their combination , as well as the non - linear interactions between structural members , the ultimate longitudinal bending moment is defined by the moment corresponding to the point with zero slope on the moment - curvature curve of the ship hull 但随着对船舶破坏机理的认识和研究发现,在研究船体的总纵极限强度时,必须考虑构件的屈曲、屈服等各种可能的破坏模式,要考虑受压构件屈曲后及崩溃后的非线性性能的影响,要考虑组成船体的各个构件发生破坏的渐进性质和相互作用等。
