zero slope meaning in English

平坡

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。
