According to the literary data the activation energy of hydrogen bonding polymeric chain with the molecules of water varies from 12 kcal/mol (polyimide) up to 18-19 kcal/mol (nylon-12) [7, 8], which is in good agreement with the results obtained in this work.
The increase in the mixing time of polymer and filler leads to even more significant reduction in β-peak (curves 4, 5).

Modern logistics is the important pillar of economic development; Green Logistics is defined as reduction of resource waste and environment pollution in the logistics process and the inevitable choice for the realization of circular economy and sustainable development.
From the result of above data analysis, the conclusion can be draw that the green degree of the reverse logistics is very good, but the economy index is fair, so various effective methods should be applied to reduce cost in order to improve green degree.

., China) with an 8-mm diameter probe, a penetration depth of 5mm and all the measurements were conducted at 4 sites on the pulp and the data were expressed as kg/cm2.
As we can see from Fig.3 that the TA value decreased for four groups during the storage periods and three treatment groups declined lower than the control group, which indicated that high oxygen treatment had obvious effect on inhibiting TA reduction.

Vertical force , кН 2472 3154 2406 3082 Analysis of the data shows that impact of external forces (operating stresses or service loads) causes stress alteration in the swing bearing, which negatively affects its elements, since a change in stresses accelerates wear of elements and leads to the equipment failure.
Corresponding reduction of unscheduled failures and improvement of coefficient of shovel technical readiness are expected.
