It is well known that well-defined polyacrylonitrile (PAN) with high molecular weight (M w > 106 g¨moí1) is an excellent precursor for high performance carbon fiber. In this work, a strategy for initiators for a continuous activator regeneration atom transfer radical polymerization (ICAR ATRP) system for acrylonitrile (AN) was firstly established by using(More)
Compared to unhealthy UV or γ-ray and high-energy-consumption thermal external stimuli, the promising light emitting diode (LED) external stimulus has some outstanding technological merits such as narrow wavelength distribution, low heat generation and energy consumption, and safety for human beings. In this work, a novel reversible addition-fragmentation(More)
Salvia miltiorrhiza, a traditional Chinese medicinal herb, contains two groups of bioactive components: lipid-soluble tanshinones and water-soluble phenolic acids. Many researchers have recently focused on elicitation of secondary metabolites to improve their production. In this paper, folic acid was used as an elicitor to stimulate phenolics production in(More)
Considering the influence of material original flaw, combining with Finite element analysis results and linear elastic fracture mechanics methods, the thesis gave a certain type of casting crane girder for example to analyze its fatigue life including the designing, remaining and service life based on fracture mechanics and the design principle of(More)
The finite element static analysis on main load bearing members of a certain type of high-pressure grouting machine used for daily ceramics is discussed in this paper for researching its stress and transfiguration. The result can provide reference for design, and the discussion has some generality and practical value engineering.
By using FEM software, two different types of hydraulic automatic tile press are analyzed, Get the deformations of the posts produced by tensile, and then calculate the energy consumption due to the deformation, through analyzing and comparing, to provide a reference on the design and selection for hydraulic automatic tile press.
By using ANSYS to carry out finite element analysis, combining the results of the analysis and the theory of fracture mechanics, and making use of damnification limits design method based on the theory of fracture mechanics, the thesis gave a certain type of casting crane girder for example to analyze its fatigue life. It provided some theory basis and(More)
