前言
天然气是一种洁净环保的燃料，在能源、交通等领域具有十分诱人的前景。其中天然气的液化和储存是一项非常关键的技术，并且它已经形成了一个系统的产业链。天然气技术作为世界一门新兴的工业正在飞速发展,目前仍保持着强劲的势头,我们为从事这样一项新兴的行业感到自豪．天然气行业作为一个朝阳产业，有着很大的开发前景，我们作为其中的一份子一定会为它的蓬勃发展进献自己的一份绵薄之力。
通过在党校四个多月的培训,让我们在理论方面都有了一定的基础,唯一不足的是缺乏熟练的操作技能．单位为了丰富我们的实践能力，在绿能高科LＮG工厂为我们安排了从２0１2年１0月29日至11月23日将近为期一月的实****并且采用了师傅带徒弟的模式，让我们能更好的融入,学到更多的知识.
为期一月的实****生活马上就要开始了,同时我们也会带着高涨的热情投入其中，争取在实****中勤动脑、多动手让自己能得到更大的收获.
