The mechanism of underground solidification and induration of cement clay grout is emphatically discussed and tested and vertified in engineering. 簡要介紹了高壓噴射灌漿新技術(shù)的原理，重點(diǎn)論述了水泥粘土漿在地下的固結(jié)與硬化機(jī)理，并以工程實(shí)踐作了驗(yàn)證。
Infected mandibular, parotid and anterior cervical nodes usually cause subcutaneous induration and surface bulging. 感染的下頜，耳下和頸前淋巴結(jié)，通常引起皮下硬結(jié)和表面突起。
