The data in the second heating process was recorded.
Combining all the analysis above, we believe that terminal carboxyl reduction is in accordance to the mechanism of polycondensation of PLA by molten/ solid-phase method [6-13], which means it is induced by molten/condensation reaction of the oligomer in PLA.

Introduction Serious soil erosion in sloping land under rainstorm runoff has caused soil nutrient losses and reduction of soil productivity.
According to the data from the second national soil survey, the total area of farmland suffering from soil erosion is 4.54×107 hm2, mainly in sloping land, and the area of sloping farmland is 4.65×107 hm2, accounting for 35.09% of total farmland area.

Indeed, numerous studies on bonding techniques compared to welding and riveting have been conducted for a great number of materials and applications [1,2] and a good adhesive bonded joint offers several advantages compared to other conventional joining processes, namely acoustic insulation, vibration attenuation, structure lightening, reduction of corrosion problems and a more uniform stress distribution [3].

The related results are summarized as follows: The FE bridging model is verified for both mode I and mode II and agrees well with available experimental data.Our numerical results indicate that chopped fiber can greatly improving interface fracture toughness of piezoelectric composite, which can effectively suppress the crack propagation, whether the voltage is positive or negative.
For the three different laminates studied in this work, the effect of chopped fiber reduced in the peak toughness of GI and GII were significantly different, but the reductions in total G were all about 18%.

Anyhow, the measured adhesion forces cannot be assigned to certain surface terminations, since no data concerning adhesion forces between the Si-tip and oxygen, hydrogen or carbon were found in literature.
Upon further addition of Si composite thermal conductivity κc tends to decrease, which may be ascribed to a reduction in matrix thermal conductivity κm, caused by an increased proportion of residual dissolved Si.

The porosity can be calculated by the following format: For each scaffold, at least three replicates were analyzed and the data represents the average of the values obtained.
The columnar sample was compressed at a crosshead speed of 1mm/min until ~50% reduction in specimen height. the compressive strength was calculated by the format: , is the maximum strength put on the sample, is the contact area of sample with crosshead, The samples were measured triplicate to get an average.

The direct benefit of the increased cooling temperature is the reduction in the cost of the cryogenic system and the improvement in cooling efficiency.
The signal-acquisition part monitors various technical parameters of the power system and SMES, and provides basic electrical data to the controller for power-system state analysis.
