Column Fractionation of High Pressure Polyethylene and Physical Properties of the Fractions
Kobunshi Kagaku, 1969 1009の大量分別により得られた1区分約10gの分別試料を用い, 広範囲な分子量範囲にわたり, 高圧法分岐ポリエチレンの力学的性質を明らかにした。力学的性質に及ぼす短鎖分岐の影響については, エチレンとプロピレン, ないしブテ-1との共重合体と高圧法分岐ポリエチレンとを比較することにより, また長鎖分岐の影響については, 一連のcharacterizeした高圧法ポリエチレンの測定試料を用い, 分布の影響については分別試料, 未分別試料を用いることにより明らかにした。一般にいわれているように, 分布幅の狭い試料は強い強度を有することは, 高圧法分岐ポリエチレンにもあてはまった。さらに各種強度と基本的物性 (分子量, [η], 密度など) との関係を広範囲な分子量域にわたって測定した結果より ...

REVIEW OF SOME PROMISING FRACTIONAL PHYSICAL MODELS [PDF]
International Journal of Modern Physics B, 2013 Fractional dynamics is a field of study in physics and mechanics investigating the behavior of objects and systems that are characterized by power-law nonlocality, power-law long-term memory or fractal properties by using integrations and differentiation of non-integer orders, i.e., by methods in the fractional calculus.

On the physical interpretation of fractional diffusion
Comptes Rendus. Mécanique, 2018 Even if the diffusion equation has been widely used in physics and engineering, and its physical content is well understood, some variants of it escape fully physical understanding. In particular, anormal diffusion appears in the so-called fractional diffusion equation, whose main particularity is its non-local behavior, whose physical interpretation ...
