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的原理，重點論述了水泥粘土漿在地下的固結與硬化機理，并以工程實踐作了驗證。
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，通常引起皮下硬結和表面突起。
