(3) monitoring contract monitoring equipment installed and buried timely records after the initial reading, and according to the technical terms and the technical requirements to monitor contract work 的一大难题，于是在实习时我便有意观察前辈们是如何和同事以及上级相处的，而自己也尽量虚心求教，不耻下问. 4.社会需求及专业发展、自我定位 目前，我国煤、油气和金属矿产资源的勘探、开发以及岩土工程勘察和地质灾害防治方面的任务艰巨，但相关企业地质人才严重短缺，因此，培养高素质的地质人才是国民经济建设之急需。众所周知，地质类专业为长线艰苦专业，工作环境较差，不是野外就是井下，若没有吃苦耐劳的敬业精神，是搞不好本职工作的，也难以出成果，大部分学生受社会不良思潮的影响，贪图享受，吃苦受累精神不足。就我而言，必须更好地了解社会人才的需求，从而做到因社会而学，因需要而学，做好思想准备，严格要求自己，不怕吃苦，力争在此行业从基础做起，理论联系实际，逐步壮大自己的专业理论知识。为将来的发展做下坚实的基础。 ical terms and the technical requirements to monitor contract workoring contract monitoring equipment installed and buried timely records after the initial reading, and according to the technmonitdrilling operations. 2) drill backfill: cement mortar or grout. 3) concrete: including concrete work at the Observatory.
