Trying to operate beyond the limiting intensity would create unwanted nonlinear effects in components of the laser, impairing the beam quality and even damaging the components. 如果嘗試在極限強度之上運轉，雷射元件便會產生不當的非線性效應，輕微則降低光束品質，嚴重甚至會損壞元件。
The effect of the crack eccentricity ratio on the stress intensity factor and the ultimate tensile strength for cracked ductile plates was investigated in this paper. 摘要疲勞裂紋對船舶結構強度具有不可忽視的削弱作用，在過去的研究中，主要從斷裂力學的角度對疲勞裂紋應力場進行分析，而對於靜態裂紋板的極限強度的探討相對較少。
