ABSTRACT Drawing a clear overall picture of consumers' preferences for food is essential designing effective marketing strategies and promoting healthy sustainable system. Based on China's unique culture system, this study describes the Chinese value system designs best−worst scaling survey with 2165 respondents to explore structure. Results show that consumers have similar values Western consumers, who all rank safety, nutrition, taste as important origin appearance least important....
The method of the power spectrum density analysis is introduced, which had been used to evaluate imperfect surface figure optics, analyze spatial frequency distribution near field at condition beam nonlinear propagation.
The characteristics of linear propagation and amplification pulse in the high-power solid-state laser system were analyzed. decomposition different parts this was also made. And controlling means for beam quantity put forward. At same time, measured near field far TIL (Technical integrated experiment line, prototype SGIII (the Laser facility ICF China) discussed, which proved these valid. These results theoretical analysis research become general idea investigating problem system.
Diffractive optical element (DOE) can be used for beam smoothing, owing to its high light efficiency, design flexibility and so on. The phase of the DOE considered as an optimization problem optimized by many kinds algorithms. In this paper, hybrid algorithm, merging Hill-climbing with Simulated Annealing, is adopted DOE. designed sum sine function different period, amplitude initial phase, which continuous ensured. fabricated ion etching, a rotating hollowed-out mask. Experiments smoothing...
This paper aims at the request of dividing harmonic waves in high power laser system used to perform Inertial Confinement Fusion. Dividing is realized by introducing binary optical element. Based on scalar diffraction theory, distribution its field was calculated and fabrication parameters were also optimized. The element fabricated with RIE. We measured relief structure efficiency each wave analyze errors.
