We have built a physical model about macromolecule's chain conformation by applying the methods of physics, and then we have mainly simulated macromolecule chain's conformation. We also have studied the single chain system conformation's size which represented by mean-square end to end distance R2 and mean-square radius of gyration R2, shape and the variation of energy which acted between different chain lengths. The results shows that the average energy Ec and the size which represented by mean-square end to end distance R2 and mean-square radius of gyration R2 are proportional to the variation of chain's length. When the chain lengthens, the distribution of chain conformation in a small size area will be expanded and increased. When the chain length reaches from 10 to 16, chain conformations are mostly distributed the area with high energy and small size. © 2011 IEEE. Source

This paper studies the Beijing Energy consumption and energy intensity of the present and future. First, the paper studies the energy situation in Beijing, including consumption, energy intensity and energy mix. Then through a combination of foreign experience and the status quo, we point out the general rules of energy growth and the various factors affecting the growth of energy consumption in Beijing. Next article is about the future of Beijing's total energy consumption for a short-term and long-term forecasts and Beijing's energy saving potential related analysis are also presented. Finally concluding remarks, the author points out the problems and findings which are conducive for Beijing to build green low-carbon city and construct a world city. © (2013) Trans Tech Publications, Switzerland.

We have acquired the approximate method about how to get macromolecule's relaxation spectrum by means of experiment data. Depending on steady state stress relaxation experiment or dynamic shear experiment, we have gotten steady state relaxation modulus function G(t) or dynamic state modulus function G′(ω) and G″(ω). And then we have calculated all the approximate solutions of relaxation spectrum H(λ). Depending on the melt storage modulus G′(ω) data and power cost modulus G″(ω) data which from dynamic linear small swing shear oscillating experiment, we have calculated discrete relaxation spectrum in accordance with the approximate formulas which proposed by Schwarzl and staverman. At last, we also have discussed the affection of discrete relaxation spectrum which caused by some parameters and temperature. © 2011 IEEE. Source

On the basis of equant roll calender, we have designed non-equant isometric roll calender which applied in macromolecule material. This kind of calender can be realized by decreasing the diameter of one or two rolls properly. And a pair of non-equant roll calender can be constructed by means of one big roll and one small roll. During the process of design, we have built the corresponding mathematical model. And we have calculated the non-equant roll calender's key problems in accordance with this mathematical model. By comparing with traditional calender, non-equant roll calender has such advantages as high precision, low pressure load, low power consumption and rapid speed. © 2011 IEEE. Source
