The experimental results of stress relaxation and constant load tests in hydrogen charging condition prove that hydrogen has dual action of softening and hardening steel.───充氢条件下应力弛豫和恒载荷拉伸试验结果表明，氢有引起钢的软化和硬化的双重作用。

The elastic range, the plastic range (during which the material flows at a constant stress), the strain-hardening range, and the range during which necking occurs, terminating in fracture.───弹性范围，塑料范围（当材料以不变的应力流动时），应变硬化范围和发生颈缩现象以其断裂终止的范围。

rammed earth with minimal moisture loss at relatively constant temperature for period necessary for hydration of cement and hardening of rammed earth.───在相对稳定的温度下，确保夯实墙的最小湿度，以保证水泥的水化和夯实墙的硬化。
