distance modulus

基本解释

The conclusion is that the elastic modulus of plastic concrete is more accordant with the real condition if the full length of the specimen(300mm) is adopted as the standard distance.
同时，还对不同原材料用量和不同试验条件对塑性混凝土弹性模量的影响规律进行了初步探讨。
The affected elements are analyzed in comparison with previous result, which mainly are dimensionless frequency, the elastic modulus ratio of pile to soil, and the distance between two piles etc.
在对所得结果与前人工作结果比较的基础上，提出考虑轴向力作用时的影响因素，包括桩土之间的弹性模量之比、无量纲频率及桩距等。算例表明，这一方法具有更可靠的计算精度。

a measure of the distance, r, of a celestial object too far away to show measurable parallax. It is given by mM = 5 log(r/10), where m is its apparent magnitude (corrected for interstellar absorption) and M is its absolute magnitude
