( 4 ) by use of dynamic strain testing , the ultrasonic wave , bedded composite rock damage and fracture mechanisms and the fragmentation process during blasting have been experimentally studied ( 4 )運(yùn)用超動(dòng)態(tài)應(yīng)變測(cè)試技術(shù)、超聲波檢測(cè)儀對(duì)層狀復(fù)合巖體的爆破損傷破壞機(jī)理和破壞過程進(jìn)行了實(shí)驗(yàn)研究。
If a drug could be made that inhibits this fragmentation process , it could substantially slow the spread of prions , which cause mad cow disease and scrapie in animals and , in rare cases , creutzfeldt - jacob disease and kuru in humans 藥物可阻滯這些蛋白裂解片段過程,從而持久的減慢朊病毒傳播,包括瘋牛病和綿羊瘋癢病和一些人類罕見疾病克-雅二氏病和庫魯病等疾病的傳播。
And with the introduction of the modulus of elasticity from budiansky method , the general damage model of rock blasting is established in the paper . by use of the ultrasonic wave , rock damage and fracture mechanism and the fragmentation process during blasting are studied , and the theory presented in the paper has been proven 運(yùn)用超聲波等手段對(duì)巖石爆破損傷斷裂機(jī)理和破壞過程進(jìn)行了試驗(yàn)研究,分析了不同爆破條件下巖石內(nèi)部微裂紋的擴(kuò)展規(guī)律、損傷演化和巖石破碎規(guī)律,驗(yàn)證了本文理論部分的正確性。
