Environmental service industry is not only the environmental protectionmaterial basis and the technical support, but also an important aspect ofexpanding domestic demand, to maintain growth, adjusting structure. In this paper, based on the research status of environmental protection industry of Liaoning province in 2012, the "Twelfth Five Year Plan" period of environmental protection industry in Liaoning province development needsand promote the environmental protection industry development in Liaoning province and countermeasures. © (2014) Trans Tech Publications, Switzerland.

In order to simulate the hot-dipped galvanizing of dual-phase (DP) steel (wt%) 0.15C-0.1Si-1.7Mn, the DP steels were obtained by different annealing schedules. The effects of soaking temperature, time, and cooling rate on ferrite grain, volume fraction of martensite, and the fine structure of martensite were studied. Results showed that the yield strength (YS) of DP steel is sensitive to annealing schedule, while total elongation has no noticeable dependence on annealing schedule. Increasing soaking temperature from 790 to 850 °C, the YS is the lowest at soaking temperature of 850 °C. Changing CR1 from 6 to 24 °C/s, the YS is the highest when CR1 is 12 °C/s. Increasing soaking time from 30 to 100 s, the YS is the lowest at soaking time of 100 s. Besides, it was found that sufficient movable dislocations within ferrite grains and high martensite volume fraction can eliminate yield point elongation, decrease the YS, and increase ultimate tensile strength. Through TEM observations, it was also found that increasing annealing temperature promotes austenite transformation into twin martensite, and increases volume fraction of martensite at sufficient cooling rate. With increasing the martensite volume fraction, the deformation substructure in the ferrite is well developed. © The Chinese Society for Metals and Springer-Verlag Berlin Heidelberg 2014. Source

The corrosion behavior of low-carbon steel (CS), P-bearing steel (PS) and P-RE weathering steel (P-REWS) exposed for two years in Jiangjin of China was investigated. The results showed that during 2-year exposure test, corrosion data of the experimental steels followed the bilogarithmic equation, and the average corrosion depth of PS and P-REWS was decreased by 19.5% and 28.2% respectively compared with that of CS. Scanning electron microscope, electrochemical impedance spectroscope and Fourier transform infrared spectroscope were used to characterize the corrosion products. The research results showed that P in steel could promote the formation of an amorphous ferric oxyhydroxide layer near the substrate. The addition of RE could effectively increase the charge transportation resistance of rust. © 2011 Central Iron and Steel Research Institute. Source

Based on the research of plant taxonomy and botanical investigation, microscopic characteristics of the root, stem, leaf transverse section and powder of Atropa belladonna were studied for identification of the herb. The research detailed and made clear to the description identification and microscopic characteristics of officinal parts of the herbs. The work provided reference for the identification of A. belladonna herbs and pieces of work in the future, as well as a theoretical basis for the further research, development, medicinal use and the upgrading of quality standards.
