crack spacing 中文意思是什麼
crack spacing
解釋
裂紋間距-
For the nitrogen - implanted samples, the initiation of crack is greatly delayed, and crack spacing interval is small. the samples prepared by pecvd and piii technologies have been investigated using homemade gas permeation tester. the excellent barrier
而注入件相對沉積件而言，由於沒有明顯的界面層，而表現為改性層裂紋間距小，但沒有完全開裂，具有優良的耐失效性能。 -
It is shown that the proposed model can not only take the ratio of reinforcement, the material properties of reinforcement and concrete and the crack spacing into account, but also be easily incorporated in finite element programs
該模型不僅有效地反映了配筋率、裂縫間距以及鋼筋和混凝土材料特性等因素對鋼筋混凝土開裂后性能的影響，並且很容易在現有的有限元程序中實現。 -
The test results indicated that : crack similitude of reinforced concrete simple beams is not equal to model scale under the working load ; when the amount and surface shape of reinforcing bar are same, the similitude of crack width, crack amount and crack spacing of reinforced concrete simple beams of different scales are all nearly equal to the square root of model scale ; when the amount and surface shape of reinforcing bar are different, the similitude of crack amount and crack spacing are still nearly equal to, whereas the crack width is not only approximately proportional to, but the influence of the amount and surface shape of reinforcing bar on crack width should be considered also at the same time
試驗結果表明：在使用荷載下，鋼筋混凝土簡支梁的裂縫相似率並不等於幾何相似比；當鋼筋根數及形式相同時，不同模型比尺下的鋼筋混凝土簡支梁的裂縫寬度、裂縫條數及裂縫間距的相似率，均約等於模型幾何相似比的平方根；當鋼筋根數及形式不同時，裂縫條數及裂縫間距的相似率仍然約等於，而裂縫寬度的相似率近似與成正比，但應同時考慮鋼筋根數與鋼筋表面形狀對裂縫寬度相似率的影響。 -
Then, taking the maximal tension stress in surface and base and the stress intensity factor at the top of the induced crack as restraining indexes, method to determine the reasonable induced spacing has been determined
然後以預切縫上端應力強度因子、面層與基層內的最大拉應力為約束指標建立了合理預切縫間距的確定方法。
