The behaviour of some materials, notably structural steel, can often be approximated by a stres-strain curve . 某些材料的受力状态，比如值得注意的钢结构，通常可以近似地用应力--应变曲线来描述。
A material is completely characterized when the identity and position of all of its constituent atoms are known . 如对某种材料的组成原子的等同性与位置都了解了，那么，该材料的品质就完全鉴定了。
Choice of materials for physically isolating individual trees or groups of trees may be less critical than in the case of flowers . 对单株木和群集木物理隔离材料的选择，也许没对花朵的那么讲究。
The non-linearity of the curve in this region of low exposure gives rise to problems in the calibration of photographic materials . 在低曝光量区域，曲线的非线性将给照相材料的定标带来一些问题。
The conventional photoelastic modes and procedures suffice to indicate whether or not the yield point of the material of the prototype will be exceeded . 常用的光弹性模型和方法能够指明原型材料的屈服点是否将被超过。
Another problem in the determination of a good representative value of the conductivity for a given rock type arises from the heterogeneity of the material . 测取给定岩类具有良好代表性热导率数据的另一个问题是材料的不均匀性。
This attitude coupled with a degree of "witch doctor" chemistry surrounding admixtures had led to a slow and reluctant acceptance of these materials . 对外加剂的化学作用带有某种程度“巫医”的看法，使得这些材料的应用缓慢而勉强。
A fact of great importance for geology is that brittle materials such as rocks tend to become ductile when subjected to large hydrostatic pressure . 地质水中一个十分主要的事实是：当受到很大水压时，脆性材料如岩石等有变成延性材料的趋势。
