The result indicated that we can get stable homopolymer and copolymer emulsion with uniform size distribution, when the ratio of sodium polyether sulfovinate modified polysiloxane to sodium lauryl sulfate was two, the quantity of the emulsifiers ranged from 6% to 8%, the quantity of initiator ranged from 0.4% to 0.8%, the stirring speed ranged from 200rpm to 250rpm, the polymerization temperature was 80 centigrade degree. As for the copolymer emulsion, the more the TRIS content in the monomers, the larger the water contact angle of their films became, namely, the surface energy of the copolymer films increased with the TRIS content in the monomers. In addition, the glass-transition temperature of the copolymers ranged from high temperature region to low temperature region with the increasing of TRIS content in the monomers.

At last the paper realized the advantages and disadvantages of passive solar building and adnvanced some suggestions in future research. From another point, the paper logged the process of the building of the experimental equipment and the mounting of the measurement equipments that accumulated some operating experimence.Carrying experiments, calculating and analyzing the experimental data for more than 2 years, the paper gained some constructive conclusions. In winter the indoor air temperature and RH are lower than comfort criteria, but people feels very comfortable in the passive solar house. The thermo-circulation formed by Trombe wall play an important role in improving indoor air temperature and RH. Based on the analogy analysis theory, the natural convection heat transfer in the air gap can be treated as superposition of two natural convection heat transfer processes occurring over isolated isothermal vertical flat plate, in this case namely the massive wall and glazing. Two empirical formulas for Q and Nu are obtained. The investigation shows that the optimal time to open the damper should comply with the period that the thermo-circulation happens which can be controlled by thermal response characteristics of Trombe wall surface temperature and air temperature in the air gap.

Consolidation test is a important link of obtaining mechanical properties index of soil and coefficient of compressibility gained through the test is a key data to evaluating the compressibility of soil. Consisting of solid phase and liquid phase of the salty soil is different from the non-salty one. Eutectic salt in soil may exist as liquid phase, solid phase or both of them and these phases can interconvert because it is affected by temperature, Na_2SO_4 content, water content. Especially when temperature drops, Na_2SO_4 will crystallize and expand, namely salt expansion of soil. These particularities make soil sample put in environmental cabinet when consolidation test is going on. So soil sample can be compressed by temperature controlling system under a set temperature.From experiment, the formulae counting coefficient of compressibility of salty soil have been given.

The results show that Fe0.13[Co20Ni80]0.87 alloy fibers are characterized with thin diameters between 0.3 and 2.0 μm, with high aspect ratio, dense and smooth surfaces. The crystalline size of the alloy fibers are mainly influenced by the thermal reduction temperature and are in the range of 20 to 50 nm with a corresponding reduction temperature range of 300 to 700 ℃. The magnetic properties of the alloy fibers are largely affected by the carbon content and crystalline sizes of the alloy fibers. With increasing thermal reduction temperature, the coercivity decreases while the saturation magnetisation value of the alloy fibers dramatically increases at lower reduction temperatures. The alloy fibers prepared at reduction temperature of 700 ℃ have a saturation magnetisation value of 120 Am2/kg and a coercivity value of 10.4 kA/m, respectively.

The results show that the mechanical properties of this PMMA depend strongly on the testing temperature. The Young's modulus and flow stress were found to decrease with increasing temperature at low strain rate. At the strain rate of 10^(-1) 1/s, strain soften was observed under all experiment temperatures. At high strain rate, with the temperature increase, the flow stress deceases remarkably while the failure strain increases, and the strain softening was also observed at the temperature above 333K.
