The research shows that the conductive coat has definite application for monitoring tiny crack in bridges and tunnels 该研究表明:导电涂膜对桥梁、隧道的裂缝监测具有一定的工程应用前景。
When cracks form , they repair like wounds . scientists the university of illinois have created a synthetic material that automatically seals any tiny cracks that develop within it 伊利诺伊大学的科学家创造了一种合成材料,它能自动愈合内部的任何细微裂纹。
The conductive coat has been applied on concrete test blocks during the compression test , the data shows that the conductive coat is rather sensitive to formation and extension of tiny cracks 将导电涂膜应用于混凝土试块的抗压试验,结果发现导电涂膜在快速加、卸载条件下对混凝土微裂缝的出现及扩展相当敏感。
This product is a highly effective and penetrating - tylpe water - proofing agent that is also environmentally friendly and has strong chemosmosis integration properties that can remedy tiny cracks in the substrate materials and is also permeable to air 产品功效:本品为自然渗透型石材防护剂,高效、环保、化学渗透结合力强,能弥补石材细小裂缝,具有透气性。
As a child , she often had crept to the door and , peeping through the tiniest crack , had seen ellen emerge from the dark room , where gerald ' s snores were rhythmic and untroubled , into the flickering light of an upheld candle , her medicine - case under her arm , her hair smoothed neatly into place , and no button on her basque unlooped 到了孩提时期,她常常爬到房门边,从缝隙里朝外窥探,看到艾伦出现在黑暗的房门口,擎着一支忽隐忽现的蜡烛,走了出去,她臂上挽着药袋,头发一丝不乱,上衣的钮扣也没漏掉一颗没扣上,此刻杰拉尔德却没有受到干扰,正在发出均匀的鼾声。
Steel fiber scatters stress converging in the area of the top end of tiny cracks , restrict the occurrence and development of cracks , diminishes the width of cracks , and enhances the integrity of concrete with the occurrence of cracks via the effect of felting between concrete and steel fiber , and consequently the strength of concrete that resists compression , tension , and shear force increases obviously , and the capability of concrete that resists compact , and fatigue , and the ductility and durability of fissured concrete improve 钢纤维削弱了混凝土微裂缝尖端的应力集中、限制并约束裂缝的产生和开展、减小裂缝宽度、尤其是通过粘结作用提高了裂后混凝土的整体性,从而使混凝土的抗拉、抗弯、抗剪强度显著提高,其抗冲击、抗疲劳、裂后韧性和耐久性也有较大程度的改善。
During the fabrication or service , if the applied tensile stresses exceed the probabilistic tensile strength of silicon , then failure will occur . even a tiny crack will bring tremendous damage to devices and circuits . especially nowadays , with the increasing of silicon wafer diameter , warpage in heat treatment , defects and dislocations generated in silicon often become critical problems in ulsi devices fabrication 特别在大规模集成电路与器件生产中,一个微小的裂纹就可能导致后道工序中电路与器件的完全损坏;而且在热处理过程引起的翘曲,使光刻精度下降;在硅片内部产生的氧沉淀及位错等缺陷,会导致集成电路或器件的漏电流增加,使器件失效。
