A key test of the biological hypothesis for ALH 84001 is the formation temperature of the carbonates that contain the putative fossil evidence.

对84001生命假说来说，一个重要的测试是这个化石里碳酸盐的形成温度。

Some of the solid material it brings up may come from a so-called diamond-stability field, where conditions of pressure and temperature are conducive to the formation of diamonds.

它所带出的一些固体物质可能来自所谓的钻石稳定场，那里的压力和温度条件有利于钻石的形成。

Iron as an element is a solid. That's it's most stable state at room temperature and pressure, right, and so on. And then we can figure out heats of formation.

铁单质是固态，这是他在室温和常压下，最稳定的状态，然后我们，可以算出生成热，现在这个。

Delta H of formation means the enthalpy of this compound minus the enthalpy of its constituent elements in their most stable state at room temperature and pressure.

生成焓就是这种组分,的焓减去它的所有组成元素,在室温和常压下处于,其最稳定的状态时的焓。
