There are basically two sources: renewable resources such as forests and fisheries, and exhaustible resources such as copper, coal and oil.

主要来源有两个：可再生资源，如林业和渔业；不可再生资源，如铜矿，煤矿和石油。

In this paper,author's research starts from the thermal expansivity and thermal transmission theory in physics,then utilizes the thermo elastic theory in mechanics of elastic bodies and the solution of statically indeterminate system in mechanics of materials as well as the interaction principle between soil and elastic body,finally gets the correct thermal stress analysis formulae of shaft-wall.

长期以来，在基岩段井壁结构的设计中，一直将地压作为结构设计的影响因素，实际上是不完善的；对于煤矿的进风井，井壁的温度随季节而变，因此，温度因素同样的应该考虑到井壁结构的设计中去；因此，将遗漏的因素补充入传统的设计理论中，是目前十分紧要的一项研究工作。

I think we are short-sighted in not exploiting our own coal.
