Active carbon-ceramic sphere as support of ruthenium catalysts were evaluated through the catalytic wet air oxidation (CWAO) of resin effluent in a packed-bed reactor. Active carbon-ceramic sphere and ruthenium catalysts were characterized by N2 adsorption, CO chemisorption and SEM measurements. BET surface area and total pore volume of active carbon(AC) in active carbon-ceramic sphere increase with increasing KOH-to-Carbon ratio, AC in the sample KC-120 possesses values as high as 1100 m2g-1 and 0.69 cm3g -1(carbon percentage: 4.73 wt. %), especially. Active carbon-ceramic sphere supported ruthenium catalysts were prepared using the RuCl3 solution impregnation onto KC-120, the ruthenium loading was fixed at 1-5 wt. % of AC in the support. As optimum catalyst, the 3 wt. % Ru/KC-120 catalyst displays the higher stability in the CWAO of resin effluent during 30 days. Chemical oxygen demand (COD) and phenol removal were about 92% and 96% at the reaction temperature of 200 oC, oxygen pressure of 1.5 MPa, the water flow rate of 0.75 L h-1 and the oxygen flow rate of 13.5 L h-1.

The sequence stratigraphic division and correlation are the key of the research for glutenite reservoir. For the reasons that lacking shale marker horizons and paleaobiological fossils in glutenite sediments, the conventional treatments of strata demarcation based on well logging are difficult and inefficient. Aimed to the great thick glutenite in Dongying Depression, this paper presents a new method of wavelet analysis based on DB5 continuous wavelet transform to make sequence stratigraphic division and correlation. The wavelet transform is an excellent tool of multi-scale analysis, it can make strata demarcation by studying the cycle regulation of the wavelet coefficients in the best scales resulted from the CWT of the GR or AC well logs. The research shows that the method of wavelet analysis is quite suitable and effective for the demarcation of glutenite sediments and gets quite good results.

Wheat straw is one of the most abundant and cheap agricultural wastes, and it is estimated that about 250 million tons are produced annually in China. Wheat straw is predominantly disposed of by direct burning in open field due to lack of e¿ective utilization, which also causes serious environmental pollution. It is an important issue to deal with the agricultural waste both for the comprehensive utilization of lignocellulosic resources and for the prevention of environmental pollution. The aim of the present work was to investigate the suitability of wheat straw as a raw material for particleboard. In this study, phenol–formaldehyde resin was modified with polyisocyanate as an adhesive for wheat straw particleboard preparation. Orthogonal experiment design was used to study the effects of hot-press temperature, hot-press time, resin application ratio, and wax application ratio on mechanical and water soaking properties of the wheat straw particleboard. Results showed that hot-press temperature was the dominant in¿uencing factor. Mechanical and soaking properties improved as hot-press temperature increased and reached their highest point at 160¿. Hot-press time, resin application ratio, and wax application ratio also had a significant effect on mechanical and water soaking properties of the board. The optimum manufacture condition was 160¿ for hot-press temperature, 6 min for hot-press time, 20% for resin application ratio, 0.7% for wax application ratio. Under the optimum condition, 11.9 Mpa of the modulus of rupture, 0.30 Mpa of the internal bond and 4.8% of the thickness swell were obtained, higher than the requirement of JIS A 5908.
麦秸是最丰富、最廉价的农业废弃物之一，据估计，中国每年生产约2.5亿吨麦秸。麦秸主要采用露天焚烧的方式处理，缺乏有效利用，造成严重的环境污染。农业废弃物的处理是综合利用木质纤维素资源和防止环境污染的重要课题。本研究的目的是研究麦秸作为刨花板原料的适用性。以聚异氰酸酯为粘合剂，对酚醛树脂进行改性，制备麦草刨花板。采用正交试验设计，研究了热压温度、热压时间、树脂用量、蜡用量对麦草刨花板力学性能和浸水性能的影响。结果表明，热压温度是主要的影响因素。机械性能和浸泡性能随着热压温度的升高而改善，并在160℃时达到最高点。热压时间、树脂用量和蜡用量对板材的力学性能和浸水性能也有显著影响。最佳工艺条件为热压温度160℃，热压时间6 min，树脂用量20%，蜡用量0.7%。在最佳条件下，试件的断裂模量为11.9 Mpa，内部粘结强度为0.30 Mpa，厚度膨胀率为4.8%，均高于JIS A 5908的要求。

The goal of the environmental education should not merely train students' environmental knowledge, the more important thing is that it trains students' environmental morals and forms the behavior which is favorable to the environment, and these can only be formed by practice in real life. In the traditional teaching model of practice, one teacher can only guide one practice at the same time. With the development of network technology, teacher can guide the different practice activities starting up in different locations or in different times by network. Based on the integration of practical need and interactive characteristics of environment education, the author put forward a web-based environment education mode named “practice-interactive- participate in”. The Core of this mode is to train students’ environmental morals by practice and to realize teachers’ instruction through network. It also integrated the practical demand of environmental education and interactive characteristic of network teaching. This mode of teaching includes three parts: "Walk close to the nature --The cognitive education of environment ", “Experience the nature --Attitude and affective education ", “Protect the nature --The education of environmental behavior".
