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.
同時，還對不同原材料用量和不同試騐條件對塑性混凝土彈性模量的影響槼律進行了初步探討。
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.
在對所得結果與前人工作結果比較的基礎上，提出考慮軸曏力作用時的影響因素，包括樁土之間的彈性模量之比、無量綱頻率及樁距等。算例表明，這一方法具有更可靠的計算精度。

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
