Ever since the first proposal of the presence of β\|Fe in 1885 by Osmond, a great debate on the cause of quench hardening of steels was going on until 1922 when Westgren and Phragmén disproved the presence of β\|Fe by high temperature X\|ray diffraction analysis.

自从Osmond在 1885年首次提出β Fe以为，直到 192 2年Westgren和Phragm啨n用高温X射线衍射证明β Fe与α Fe有相同的体心立方结构为止，在很长时间内，冶金学家一直为钢为什么在淬火后变硬而争论不休。

Sanidinite (some have transformed to perthite) and quartz inclusions with radial cracks are often seen in the garnet of eclogite. The geothermal gradient of ＜10℃/km is recorded in the early stage mineral assemblage of high-pressure metapelitic rocks with relict aragonite. these features imply a possibility that there may be ultra-high-pressure rocks existed in Altun.

根据榴辉岩中石榴石常见透长石和石英包体，并有放射状裂纹的特征，以及高压变泥质岩石早期矿物组合温压条件记录的地温梯度小于10℃/km和残存文石等特征，不排除区内有超高压变质岩石存在的可能性。

而茎已完全木质化的1年生松幼苗和4～5年生幼树离体枝感染松材线虫后，外部症状表现为发病叶褪绿、变红褐色或褐色且萎蔫，症状首先出现在叶基部，很快向叶尖扩展，至整个针叶枯萎死亡。

When attacked by this isolate, the color of young Porphyra gametophytes turned green.

当遭到此菌侵害时，幼苗期的紫菜配子体的颜色变绿。

The results show that the reverse martensitic transformation start temperature increases with the increase of prestrain, which may be due to the elastic energy released by prestrain, and the energy dissipated increased by plastic deformation and the constrain effects of grains.

结果表明，逆相变开始温度随预应变增加而增大，其原因是预应变造成马氏体再取向使弹性能降低，引起的塑性变形和晶粒间的约束提高了耗散能。

The effect of training, prestrain amount and recovery annealing temperature on the shape memory effect, the absolute shape recovery ratio , and the superelasticity of Fe14Mn6Si9Cr5Ni alloy is studied.

研究了训练、预应变量和退火温度对Fe14Mn6Si9Cr5Ni合金的形状记忆效应、绝对形状回复率和超弹性的影响，测定了合金的蠕变和应力松驰特性，讨论了降温ε马氏体对形状记忆效应的间接贡献。
