后危机时代中国人造板产业国际竞争力与决定因素的实证分析

在运用 RTA指数对中国人造板产业国际竞争力进行测度及国际比较的基础上，依据一般化双钻石模型构建人造板产业国际竞争力决定因素的计量模型，并利用34个国家2000—2011年间的面板数据和固定效应模型进行实证分析。结果表明：虽然受到2008年全球金融危机的负面冲击，但中国人造板产业仍具有较强的国际竞争优势；本国森林资源数量、木质原材料进口、劳动力资源禀赋、劳动力成本、技术创新、国内需求规模与质量、国际需求规模、交通运输业、人造板机械制造和外国投资限制是决定后危机时代人造板产业国际竞争力的关键因素。

ACQUISITION HARDWARE FOR DIGITAL IMAGING

Use of digital radiography is growing rapidly in veterinary medicine. Two basic digital imaging systems are available, computed radiography (CR) and direct digital radiography (DDR). Computed radiographic detectors use a two-step process for image capture and processing. Image capture is by X-ray sensitive phosphors in the image plate. The image plate reader transforms the latent phosphor image to light photons that are converted to an analog electrical signal. An analog to digital converter is used to digitize the electrical signal before computer analysis. Direct digital detectors provide digital data by direct readout after image capture—a reader unnecessary. Types of DDR detectors are flat panel detectors and charge coupled device (CCD) detectors. Flat panel detectors are composed of layers of semiconductors for image capture with transistor and microscopic circuitry embedded in a pixel array. Direct converting flat panel detectors convert incident X-rays directly into electrical charges. Indirect detectors convert X-rays to visible light, then to electrical charges. All flat panel detectors send a digitized electrical signal to a computer using a direct link. Charge coupled device detectors have a small chip similar to those used in digital cameras. A scintillator first converts X-rays to a light signal that is minified by an optical system before reaching the chip. The chip sends a digital signal directly to a computer. Both CR and DDR provide quality diagnostic images. CR is a mature technology while DDR is an emerging technology.     

橡胶树死皮病黄色体差异表达蛋白的初步分析

橡胶树"死皮病"给橡胶种植业带来严重的危害.为了更好地了解和阐明死皮病发生、发展的分子机制,研究应用双向凝胶电泳技术(two-dimensional gel electrophshiya/oresis,2-DE)比较橡胶树死皮株与健康株胶乳黄色体蛋白质组表达的差异.采用TCA/丙酮沉淀法提取橡胶树死皮株与健康株黄色体蛋白质并采用固相pH梯度(immobjlized pH graalient,IPG)双向凝胶电泳分离两种材料蛋白质,凝胶经银染显色后,用PDQuest图像分析软件进行比较分析、识别差异表达的蛋白质.成功获得橡胶树死皮株与健康株胶乳黄色体的双向凝胶电泳图谱.鉴定出13个蛋白差异点,其中10个上调表达,3个下调表达.并应用质谱技术鉴定了其中部分表达差异的蛋白质点,对渗调蛋白进行功能分析,认为渗调蛋白在死皮株中表现下调的情形可能与死皮病的发生有一定的关系.     

Sandwich panel of veneer-overlaid low-density fiberboard

Low-density sandwich panels of veneer-overlaid fiberboards of 12 mm thickness for structural use were manufactured at densities of 0.3–0.5g/cm³ using an isocyanate compound resin adhesive and steam injection pressing method. The effects of board density, veneer thickness, and resin content on the fundamental properties of sandwich panels were examined, with the following results: (1) The dry moduli of rupture and elasticity in the parallel direction of sandwich panels with thicker veneers were superior. The dry moduli of rupture and elasticity in the parallel direction of sandwich panels with 2.0 mm thick veneer at densities of 0.4–0.5 g/cm³ were 40–60 MPa, and 5–8 GPa, which were two and four times as much as those of homogeneous fiberboards, respectively. (2) The higher-density panels exhibited tensile failure at the bottom veneer surface during static dry bending in a parallel direction, whereas lower-density panels experienced horizontal shear failure in the core. (3) The dimensional stability of sandwich panels had good dimensional stability, with negligible springback after accelerated weathering conditions. (4) The thermal insulation properties of sandwich panels were found to be much superior to other commercial structural wood composite panels.Part of this report was presented at the 47th annual meeting of the Japan Wood Research Society, Kouchi, April 1997
