1·The existing retorting technology can not exploit the oil shale properly for it can cause pollution to the environment and it is high energy-consuming.
现有的干馏工艺大部分对环境存在污染，且工艺耗能较大，不能够科学、合理地开发利用油页岩资源。
2·The shale oil from oil shale by the retorting technology is an ideal substitute for nature oil.
油页岩干馏产出的页岩油可以作为一种理想的石油替代品。
3·This article envisions the trends in the development of oil shale retorting technologies and concludes that Estonia's experience and practice can be used for reference for China.
对油页岩干馏工艺的发展趋势进行了展望：爱沙尼亚经验和做法值得借鉴。
