  blend
A polyamic acid (PAA)/polyurethane (PU) blend with PU as the disperse phase was first prepared via in situ polymerization of pyromellitic dianhydride and 4,4-oxydianiline in PU solutions.
      
It was found that the size and content of pores increased with an increase in the PU mass fraction in the PAA/PU blend up to 20%.
      
They came from Arctic-Tertiary, Paleo-tropical-Tertiary and Tethys-Tertiary florisitic elements, and the blend of the three elements with many genera of autochthonous origin.
      
The surface composition of the blend films was determined by Fourier transform infra-red spectroscopy coupled with a variable incidence angle attenuated total reflection accessory (ATR-FTIR).
      
The radius of the dispersed phase in the system decreases greatly when the compatibilizer is added into the blend.

A composite element filter of absorption edge type described here can be used when the X-ray energy of the wanted element is higher then that of the interference element. It's mainly used in immersion probes. When measuring copper in copper concentrate, the absolute error of the grade achieved is mostly less than ±0.3% and this can fully meet the demand of industrial process control analysis. It can be anticipated that in other pulp on-stream analysis, a relative composite element filter can certainly be,made...

A composite element filter of absorption edge type described here can be used when the X-ray energy of the wanted element is higher then that of the interference element. It's mainly used in immersion probes. When measuring copper in copper concentrate, the absolute error of the grade achieved is mostly less than ±0.3% and this can fully meet the demand of industrial process control analysis. It can be anticipated that in other pulp on-stream analysis, a relative composite element filter can certainly be,made if the content of the neighboring element is high enough and the X-ray energy of the element to be measured is higher than that of the. interference element.Preparation of Ni-Cr composite powder, the blending ratio test of the two element, the mass thickness test at the given blending ratio, the modulation and testing of the filter performance and test measurement on the sample of natural powder are given.

A new approach, "condensed approach", is proposed for the finite element analysis of elastic-plastic materials. The total domain of the structure is divided into two regions. One is an elastic region and another is a mixed region of a plastic region blended with some elastic elements. The effects of the elastic region on the mixed region are expressed by equivalent general forces acting on the boundary nodes between the two regions. So the elastic-plastic analysis may be considered only in the mixed region....

A new approach, "condensed approach", is proposed for the finite element analysis of elastic-plastic materials. The total domain of the structure is divided into two regions. One is an elastic region and another is a mixed region of a plastic region blended with some elastic elements. The effects of the elastic region on the mixed region are expressed by equivalent general forces acting on the boundary nodes between the two regions. So the elastic-plastic analysis may be considered only in the mixed region. Because the mixed region is considerably smaller than the elastic region in general, a great deal of operation time to form the general stiffness matrix repeatedly and to solve the equations is saved and computation cost is cut down greatly. Some examples are given in illustra-tion of the approach.

The regularity of radiation crosslinking and the radiation effect on thestructure and property of LDPE (low density polyethylene)-EPDM (copolymerof ethylene-propylene) blends are reported in this paper. The results show that radiation crosslinking effect on LDPE/EPDM blendsis either similar to pure LDPE or EPDM, depending upon which one is the main component in the blends. When the content of LDPE is higher than that ofEPDM, crosslinking of the blend is close to pure LDPE. The relationship...

The regularity of radiation crosslinking and the radiation effect on thestructure and property of LDPE (low density polyethylene)-EPDM (copolymerof ethylene-propylene) blends are reported in this paper. The results show that radiation crosslinking effect on LDPE/EPDM blendsis either similar to pure LDPE or EPDM, depending upon which one is the main component in the blends. When the content of LDPE is higher than that ofEPDM, crosslinking of the blend is close to pure LDPE. The relationship betweenS+S~(1/2) and 1/R does not comply with Charlesby-Pinner's equation. While forblends rich in EPDM, a linear relationship is observed at high doses. The higherthe content of EPDM in the blend, the easier is the blend to be crosslinkedbecause of the presence of unsaturated bond in EPDM. The crystalline extent and density of the blend increases with increasingLDPE content in the blends. No obvious change of crystalline extent is observedin the dose range used. There is a close relationship between mechanical property and composition ofthe blends. The tensile strength (T_s) increases with increase in LDPE content,whereas the elongation (E%) shows a reverse effect. The effect of radiation doseon T_s is insignificant. However the elongation (E%) is seriousely affected.

文章报道了低密度聚乙烯(LDPE)和三元乙丙共聚物的共混物,经~(60)Co-γ射线辐照后的辐射交联规律以及结构与性能的变化。实验结果表明,这种共混物的辐射交联规律和单独LDPE或EPDM的辐射交联具有类似之处,其交联规律按共混物中占优势的聚合物交联方式进行。经~(60)Co-γ射线辐照后这种共混物的结构和性能发生了变化。结晶度、密度和其它物理性能与共混物中两种聚合物的组成有着密切关系。辐照剂量的改变对同一组成共混物的结晶度和密度影响较小,但是,它对力学性能有显著影响。
