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 將導(dǎo)電涂膜應(yīng)用于混凝土試塊的抗壓試驗(yàn),結(jié)果發(fā)現(xiàn)導(dǎo)電涂膜在快速加、卸載條件下對混凝土微裂縫的出現(xiàn)及擴(kuò)展相當(dāng)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 產(chǎn)品功效:本品為自然滲透型石材防護(hù)劑,高效、環(huán)保、化學(xué)滲透結(jié)合力強(qiáng),能彌補(bǔ)石材細(xì)小裂縫,具有透氣性。
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 到了孩提時期,她常常爬到房門邊,從縫隙里朝外窺探,看到艾倫出現(xiàn)在黑暗的房門口,擎著一支忽隱忽現(xiàn)的蠟燭,走了出去,她臂上挽著藥袋,頭發(fā)一絲不亂,上衣的鈕扣也沒漏掉一顆沒扣上,此刻杰拉爾德卻沒有受到干擾,正在發(fā)出均勻的鼾聲。
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 鋼纖維削弱了混凝土微裂縫尖端的應(yīng)力集中、限制并約束裂縫的產(chǎn)生和開展、減小裂縫寬度、尤其是通過粘結(jié)作用提高了裂后混凝土的整體性,從而使混凝土的抗拉、抗彎、抗剪強(qiáng)度顯著提高,其抗沖擊、抗疲勞、裂后韌性和耐久性也有較大程度的改善。
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 特別在大規(guī)模集成電路與器件生產(chǎn)中,一個微小的裂紋就可能導(dǎo)致后道工序中電路與器件的完全損壞;而且在熱處理過程引起的翹曲,使光刻精度下降;在硅片內(nèi)部產(chǎn)生的氧沉淀及位錯等缺陷,會導(dǎo)致集成電路或器件的漏電流增加,使器件失效。
