The pseudo-quaternary phase diagram of Brij35/sodium oleate/oleic acid/watersystems has been investigated, and the liquid crystal area has been identified, which covers abouttwo thirds of the whole phase diagram. The liquid crystal structure and behavior have been alsostudied by using polarizing texture, small angle X-ray scattering, ~2H-NMR and rheometer etc. Theresult shows that when the composition of the system changes along the line of AA′ in this largeliquid crystal region, the structural change iscubic→cubic/lamellar→lamellar→larnellar/hexagonal→hexagonal. Meanwhile, we made the firstattempt of systematic study of the rheological properties of the above system. The lattice constantsof cubic and hexagonal liquid crystals are 10.53 and 5.68 nm, respectively.

The Method of Testing for Asbestos in Electronic and Electric Products through polarizing Microscope and X-Ray Diffraction

引用

Journal of Power and Energy Engineering 2019年第11期7卷 35-41页

作者： Hongwei Wang Jun Liu Qiang Ma Hongwei Su Deyong Liu Junfang Li Hua Bai Institute of Industrial and Consumer Product Safety Chinese Academy of Inspection and Quarantine Beijing China Beijing Petrochemical Engineering Co. Ltd. Beijing China China Testing and Testing Group Co. Ltd. Shenzhen China

Asbestos is widely applied in such sectors as manufacturing automobiles, tractors, chemical industrial equipment, and electric equipment. Asbestos fiber is harmful to human health. Therefore, the technology of testing for asbestos in products is especially important. At present, in our country’s national specifications, there is no determination method or specification that is applicable to the asbestos in electronic and electric products. In this article, the components of asbestos in electronic and electric products are identified using the method of combining polarizing microscope with X-ray diffractometer. This method is simple, fast, highly reliable, and suitable to be widely adopted.

The Delayed Quantum Eraser Experiment Explained Classically

引用

Journal of Modern Physics 2021年第9期12卷 1183-1189页

作者： Declan Traill Independent Researcher Melbourne Australia

This paper discusses the well-known delayed choice Quantum Eraser experiment performed by Kim et al. in 2000 and analyzes it from a Classical Physics perspective. I have included a diagram of the setup used in the experiment. I show that the result of the experiment can be explained by Classical Physics and does not require “Spooky action at a distance” due to entangled particles, as Einstein famously once put it, nor events modifying the past due to the delayed choice aspect of the experiment.

Online Investigation of Optical Properties and Craze Propagation of Drawn Polypropylene Fiber by Using Interferometric Image Analysis

引用

Optics and Photonics Journal 2014年第7期4卷 165-181页

作者： T. Z. N. Sokkar K. A. El-Farahaty E. A. Seisa E. Z. Omar M. Agour Physics Department Faculty of Science Aswan University Aswan Egypt Physics Department Faculty of Science Mansura University Mansura Egypt

Pluta polarizing interference microscope was used to follow the crazing that occur on the surface of stretched polypropylene fibres at different drawing conditions. The samples were stretched until crazing initiated, and then craze propagation was monitored as a function of drawing speed and test temperature. The effect of craze dimension on their propagation velocity was taken into account. Three-dimensional birefringence profile for crazed polypropylene fibre has been demonstrated to investigate the birefringence of crazed fibre at different test times for fixed drawing speed value. Also the mean birefringence values of crazed polypropylene fibres were calculated and the results showed that, these values increased with the areal craze density. Video images were used to calculate the craze velocity. Optical micrographs and microinterferograms were presented for demonstrations.
