This paper presents investigation results on the natural ultra-fine mineral flour of crystalline silica fume (CSF) and porous quartz sand stone (PQSS) which can modify cement mortar strength under hydrothermal synthesis reaction (HSR) in the autoclave-cured condition. The replacement of cement by CSF and PQSS can signifi cantly increase the Jflerural and compressive strength which reach 22MPa and 150MPa respectively and de-crease the porosity oj the cement mortar. The ratio oj fine aggregation, standard sand to cementions material has sig nificant influence on the mortar strength. The mechanisms involved in cement and natural mineral flour and the HSR are presented. CaO/SiO2 ratio ranges from 3. 20 to 1. 11. the main hydrate phase is C2SH and there is not Tober-morite through X-Ray diffraction qualitative analysis. The new and ultra-high strength cementious material as basic material of sleeper concrete can he used in prestressed reinforcement sleeper concrete.

Degradation of microcystin-RR in water by chlorine dioxide

Due to the potent hepatotoxicity and tumor-promoting activity of microcystins, a successful removal of these toxins during drinking water treatment processes is of increasing concem. The oxidation kinetics of MC-RR by chlorine dioxide （ClO2） was studied with HPLC and characterization of the reaction products was performed with UV-spectrometry, TOC and LC-MS. Our experimental results show that the oxidation process is a second order overall and a first order with respect to ClO2 and MC-RR. The activation energy of MC-RR degradation by ClO2 is 53.07 kJ/mol. The rate constant k of the action can be increased by increasing temperature and decreasing pH value and ranged from 6.11 × 10^2 L/（***） to 5.29× 10^2 L/（mol-min） at pH from 3.44 to 10.41 at 10℃. Reaction products were determined to be organic and volatile, because they could be almost removed from aqueous solution by heating for 15 min at 60 ~C. In addition, the main oxidation products have m/z values of 1072 and are identified as dihydroxy isomers of MC-RR.

作者： Zhi Liu Xingbo Guo chong cui College of Computer Science and Technology Zhejiang University of Technology

In order to improve the efficiency and effectiveness of 2D barcode detection algorithm under complex background, detection algorithm for Data Matrix 2D bar code based on regional features analysis and locating method of line Snake algorithm is presented in this paper. Firstly, the region which contains "L-type" barcode border is selected by analyzing the features of each region. Secondly, the barcode border is located by using line Snake algorithm, and the four vertices of the barcode are fitted. Finally, the barcode is rectified by using transmission shift. Experiments show that the detection algorithm of 2D barcode has good performance, and it is better than traditional barcode detection algorithm. It has strong anti-interference capacity, and can satisfy the needs of real-time on cell phone.
