As individuals are being evaluated, they will inevitably be included in the system that can be opened solely by the evaluator and compete with others. The system also harms individual lives through two operating mechanisms: “judging one according to others” and “judging the crowd based on oneself.” The former is manifested as a standardized mechanism centered on “use” that ignores individual lives, while the latter reveals the dependence of the value evaluation system on the unstable likes and dislikes of evaluators. The combined effect of these two makes the survival situation of the subject involuntary and dangerous.展开更多

[ Method] Fertility segregation phenomenon, morphological characteristics and main agronomic characters of male sterility character of 4 kinds of barley male sterility materials 2001 - 17, 2001 - 37, 2001 - 84 and 2001 - 116 and their dedved lines were observed and researched.[ Result] Barley male sterility existed genetic phenomenon of single dominant nuclear gene caused by environmental stimulation, its sterility controlled by MS, the sterile genotype was MSms. There was stable nucleo-cytoplasmic inheritance on barley male sterility which was controlled by cytoplasmic mate sterile gene S and nuclear gene rr, and its genotype was S（rr）, this male sterility belonged to CMS type sterility. Temperature had no effect on fertility. [ Conclusion] There was stable nucleo-cytoplasmic inheritance on barley male sterility, this result played a positively promoting role in barley practical production.展开更多
Sintering shrinkage, compressive strength, bending strength, metallurgical morphology, microstructure and chemical composition diffusion of hydroxyapatite-316L stainless steel(HA-316L SS) composites were investigated....Sintering shrinkage, compressive strength, bending strength, metallurgical morphology, microstructure and chemical composition diffusion of hydroxyapatite-316L stainless steel(HA-316L SS) composites were investigated. The results show that the sintering shrinkage of HA-316L SS composites decreases from 27.38% to 8.87% for cylinder sample or from 27.18% to 8.62% for cuboid sample with decreasing the volume ratio of HA to 316L SS, which leads to higher sintering activity of HA compared with that of 316L SS. The compressive strength of HA-316L SS composites changes just like parabolic curve (245.3→126.3→202.8 MPa) with reducing the volume ratio of HA to 316L SS. Bending strength increases from 86.3MPa to 124. 2 MPa with increasing the content of 316L SS. Furthermore, comprehensive mechanical properties of 1.0∶3.0 (volume ratio of HA to 316L SS) composite are optimal with compressive strength and bending strength equal to 202.8 MPa and 124.2 MPa, respectively. The (microstructure) and metallurgical structure vary regularly with the volume ratio of HA to 316L SS. Some chemical reaction takes place at the interface of the composites during sintering.展开更多

Due to the presence of high temperatures in the furnace coupled with the corrosive marine environment swirler material showed accelerated degradation and material wastage. An investigation into the feasibility of manufacturing the existing swirler with an alternate material or coating the swirler material with a thermal barrier coating was undertaken. Based on their properties and performance, SS 304 and SS 316 were proposed as the replacement materials for the swirler. The other alternative of coating the existing swirlers with a form thermal barrier coating to observe for any improvement in their performance at elevated temperatures was also tested. Stellite, which is a Ni-Co based coating, was carried out on the MS samples and the same were exposed to same temperatures mentioned above. The performance of the available options was evaluated with respect to the grain structure of the material, the hardness value of the materials and deterioration at elevated temperatures. Investigation showed the proposed materials/ coatings like SS 304, SS 316 and Stellite coating revealed that SS 316 is the material best suited for high temperature application.展开更多
