CA-B /New-type Paraffin Emulsion compound system: Study on the Mould Preservation Property of Treated Wood

Agricultural Science & Technology 2014年第12期15卷 2053-2056,2063页

[Objective] The aim was to develop the compound system of paraffin emulsion and CA based on natural surfactants to improve the properties of anti- mould and anti-blue stain. [Method] The paraffin wax emulsion with different con- centrations of 0.5%, 1.0% and 2.0% was added into CA （0.3% and 0.5%） to obtain six groups of compound systems. The full-cell process was applied to treat the sapwood of Pinus spp. at size of 50 mm （L）×20 mm （R）×5 mm （T）. Anti-mould and anti-blue stain tests were conducted using Botryodiplodia theobromae Pat., Spergi/lus niger V. Tiegh and Trichoderma viride *** Fr. according to the GB/T18261-200. [Result] Both paraffin wax emulsion and CA-B could prevent wood against mould and blue stain. However, within a certain range, anti-mould and anti-blue stain ef- fects of wood samples treated by the compound systems reduced slightly as the concentration of paraffin wax emulsion increased. [Conclusion] The research provides references for advancing use of wood biomass resources in a more efficient and more environment-friendly way.

In order to solve water resources problems in the North China Plain, this paper explored human-nature compound water circulation system from three aspects including urban flood control, surface drainage and saline water in the central and eastern of the North China Plain. Results show that:(1) The technical methods have achieved zero increase in rainwater runoff in urban areas,(2) surface drainage depletion problems can be solved through abandoned water and river water separation method,(3) and technical method through promoting rainwater infiltration would be used to solve problem of saline water in the central and eastern parts. This research provides a new perspective to the ultimate solutions to water resources problems in the North China Plain, and a fresh research direction for the development of hydro-geological science.

Agricultural Science & Technology 2014年第2期15卷 222-224,250页

作者：王佳敏汤少怀马尔妮曹金珍王露茜北京林业大学材料科学与技术学院北京100083

[Objective]Preservation and waterproof treatment are two crucial parts in wood protection, which can not only extend the service time, but also expand the application range of wood products. [Method] This work combined CA with paraffin wax emulsion to treat wood samples, and basic properties of the compound system, such as stability （storage stability and centrifugal stability）, particle size and pH val-ue, and water repel ency （water absorption, shrinkage and swel ing） of treated sam-ples were investigated. [Result and Conclusion] 1） the compound systems of CA and paraffin latex had a favorable miscibility and stability; 2） compared with untreated wood, CA-treated samples showed poor water repel ing properties, whereas samples treated with the compound systems indicated an obvious reduction in water absorp-tion, and the shrinkage and swel ing of them were improved as wel .

基于复合系统协同度模型的跨境电商与现代物流协同评价分析

推动跨境电商与现代物流协同发展，实现商流与物流有机融合，既是提升跨境电商产业竞争力的必然要求，也是促进现代物流发展的重要突破口。而厘清跨境电商与现代物流之间的关系，评价两者协同发展水平，对于促进两者协同发展具有十分重要的意义。利用灰色关联理论，基于复合系统协同度模型，构建跨境电商与现代物流协同评价模型，对2008-2014年我国跨境电商与现代物流协同发展水平进行综合评价发现，跨境电商与现代物流各子系统有序度呈持续增长态势，但跨境电商与现代物流复合系统协同度并没有实现相应增长，一直在较低水平上下波动。这主要是因为，现代物流发展明显滞后于跨境电商，导致跨境电商与现代物流无法在系统结构与功能上形成有序耦合。因此，为更好地促进跨境电商与现代物流协同发展，既要激发各子系统功能，又要推动政府、企业、行业协会等多方主体协同合作与深度融合。
