The part influencing area of prestressing force is related to such factors as concretes elasticratio, beams sectional dimension and so on.
构件预应力局部影响区与混凝土弹性模量，梁截面尺寸等因素有关。

It is shown that Although the deformation curve under the pressure of axis is well consistent between micro-concrete and normal-concrete, the elasticratio and strength are different.
试验表明，虽然微粒混凝土和原型混凝土的轴心受压变形曲线是大体“相似”，但两者的弹模和强度存在差异。

This paper tries to introduce two suppositional variables which are named fictitious output and fictitious capital input in discussion for seeking a new method of measuring elasticratio.
