Using C12H23 as the fuel species, H3O+, CHO+, COH+, O- and OH- as main ions, total ion concentration and temperature in flame behind a V-gutter flameholder are numerically simulated by realizable κ-ε turbulent model and non-premixed equilibrium chemistry model.
Structure of the rectangle afterburner with a V-gutter flameholder is shown in Fig.1.
Besides structured grid, unstructured grid with refinement was adopted in the nearby regions of the flameholder and fuel injector.

Synthesis of guerbet alcohol acrylate aided by microwave Xu Dong1,a, Xiaohui Zhang2,b, Minghui Zhou3,c, Wenhuan Wang4,d, Jingchang Wang5,e* 1Xu Dong, Institute of Chemistry, Dalian University, China 2Xiaohui Zhang, Institute of Chemistry, Dalian University, China 3Minghui Zhou, PetroChina Sichuan Petrochemical Company Limited, China 4Wenhuan Wang, Institute of Chemistry, Dalian University, China 5Jingchang Wang, Institute of Chemistry, Dalian University, China *College of Environment and Chemical Engineering, Dalian University, Dalian, China amilksquare@163.com,bxiaohuizhang@163.com,cZhouminghui007@163.com, dwangwenhua02@163.com,e*wjc6116@163.com Keywords: Guerbet alcohol acrylate, Microwave-assisted synthesis, Reaction parameters, Esterification rate.
The structure of product was characterized by FT-IR, 1H-NMR, 13C-NMR and the effect of different reaction parameters was discussed in this paper.
This kind of heating method is based on the ability of some liquids and solids to transform electro-magnetic energy into heat and it has revolutionized cooking and chemistry applications.
As there is no systematic study on the synthetization of guerbet alcohol acrylate conducted in a microwave chemistry reactor in the previously reported literature.
The esterification reaction was performed in MCR-3 domestic microwave chemistry reactor.

For this reason, the Freezing and Thawing and Sulfate attack of concrete has been considered for years a subject of interest in researches of cement chemistry.
The concrete deterioration process is a complex physicochemical process that slowly modifies the structures of the concrete in the course of time and induces changes into its chemical and physical properties Introduction The performance of the structure can be reduced owing to a variety of deterioration factors (Chloride attack, freezing & thawing, sulfate attack, carbonation) in the concrete structure.
Especially in case of LILW waste disposal facility structure, the occurrence of deterioration phenomenon results in the reduction of durability and safety as the structure, and even significantly influences on structural integrity and leakage resistance, which can be led to more serious impact than that in the case of ordinary concrete structures.
Here, the materials used in the actual LILW waste disposal facility structure were used as the materials in this study.
In this test, it is found that nuclear power plant structure undergoes deterioration by freezing & thawing, but such influence is very slight.

The primary commercial scale application of 2195 alloy plate (an Al-Cu-Li alloy) is for cryogenic fuel tank barrel section structures.
Through-thickness anisotropy of mechanical properties in aluminum alloy plate arise from various sources, such as chemistry gradients resulting from solidification sequences during casting, grain structure and crystallographic texture gradients, and quench rate gradient after solution heat treatment.
The chemistry of the parent plate, Lot A, is listed in Table 1.
Chemistry of the Parent lots in weight % (Remainder; Al) Lot No.

Raman spectrometry has been strongly applied in studying the composition and structure of material[1-5].
Raman spectroscopy has been put into use in molecular biology[6], medicine[10], analytical chemistry[11] and nano-structure with the development of high sensitive analytical instruments, including in testing illegal and excess food additives[12].
The signals of 1295 cm-1,1162 cm-1, 1147 cm-1, 1062 cm-1 and 1036 cm-1were obvious in acesulfame potassium impurity, cyclamate and saccharin sodium owing to the structure of SO2.
Also, there existed the signal of 2968cm-1 and 2853 cm-1 owing to the structure of CH2.
Owing to the structure of SO2, the signals of 1295 cm-1, 1162 cm-1, 1147 cm-1, 1062 cm-1 and 1036 cm-1were presented obviously.
