Influence Analysis Energy and Environment with DSM

As a large burning coal country, resolving the SO2 letting problem is the most important thing in the environment protection work. Electric power industry reveals the supply's load rate declining and the discrepancy between apex and vale augments year after year. It makes the load adjustment become an imminency task in the electric power industry. The article popularizes the light power saving technology in the inhabitant living lighting power through reinforcing the DSM technology. It studies the influence on energy and environment after using the technology. It studies avoidable electricity quantity, avoidable electricity power, avoidable apex load, avoidable coal consuming and avoidable SO2 lettling. At last, it makes a concrete analysis with a city's example.     

果胶酶对莲心中黄酮类物质提取效果研究

为了有效提高莲心中黄酮类物质的提取效果,采用果胶酶辅助提取方法,研究酶解温度、pH值、酶用量及酶解时间对莲心黄酮类物质提取效果的影响,通过L9(34)正交试验设计优选其最佳工艺条件。结果表明,影响莲心黄酮类物质提取效果的主次因素为酶用量>酶解温度>酶解时间>pH值,最佳提取工艺为酶解温度50℃,pH值4.5,酶用量0.6 mg/mL,酶解时间2.0 h,在此条件下莲心黄酮类物质提取率为1.271%。该酶法提取工艺,可以在较低的温度下提高提取效果,与传统的水提工艺(90℃、45 min)相比,莲心中黄酮类物质提取率提高了28.64%。     

Construction and Realization Method for 3 -D Digital City

This paper studies the key technology in the 3 - D digital city construction, and puts forward a new method to construct and realize the 3 - D digital city. The authors discuss the dates gathering and disposal from the collection of 3 - D topograph dates, the construction and ingress of 3 - D model, the gathering and disposal of texture dates. Subsequently, to solve the problem of that the 3 - D topograph dates are greater than the 2 - D topograph, the bulk-dates optimization of 3 - D digital city is realized through the choose of appropriate DEM of linenumbers and column numbers, the 3 - D model modeling specification, the using of nodes replace, the optimization of LOD modeling. The successful operation result of Chongqing Hi-tech Development Zone 3 - D digital city project illustrates that, this system can realistic mimic status in quo of the Chongqing Hi-tech Development Zone, the system operates smoothly, and its effect is also well.     

Detecting Technology of Cabel Surface Defect Based on DSP and Image Recognition

The damage of bridge cable directly hazards the normal use of bridge and the safety of people. The paper discussed the signal acquisition and detection system which takes embedded DSP processor as core technology, combined with CCD, video decode chip, SDRAM, FLASH ROM, and established the fast measuring algorithm of the surface corrosion and damage, which includes deteminating the processing region, improving medium filter, sobel edge detection and dynamic threshold segment, close operation of morphology, computing defect area and saving. The experimental resuits show that this method implemented the real-time, non-contact and intelligence detecting of cable surface defect and gives the specifications of the system.     

Modular Design Base on Variety Theory

Variety Design not only support to short down development time, and cut down development cost, but also support to response marketing rapid, is a kind of modern design theory which apply on Mass Customization. In some way, Variety Design is a kind of design that integrates standard design and modular design, and Variety Design object is high cost and universal parts that among platform. The authors discuss the modular design role and the different between integral design, promote the method and the step of modular design, so change the low cost parts design, and give an new product based on the platform. Based on this model, they not only save the cost of develop new product, but also save time, achieve advantage which Mass produce process.     

高温预处理玉米秸秆条件的优化

对玉米秸秆高温预处理条件进行优化,以降低还原糖损失率和提高灰分去除率为目的,探讨了高温预处理时料液比、蒸煮温度、蒸煮时间对还原糖得率的影响。通过采用单因素多水平试验方法得到最优预处理条件为料液比1∶7,蒸煮温度118℃,蒸煮时间0.5 h。在此最优条件下,预处理后的秸秆还原糖损失率为1.86%,灰分去除率为35.2%。     

五台山野生迎红杜鹃组织培养技术研究

以五台山野生迎红杜鹃的种子为试验材料,比较了不同培养基配方、生长调节剂种类和浓度对迎红杜鹃组织培养的影响,建立了迎红杜鹃组织培养再生体系.结果表明:最佳消毒方式为70％的酒精浸泡30 s+8.0％次氯酸钠浸泡处理8 min+无菌水冲洗;基本培养基为Anderson+0.1 mg/LNAA;增殖培养基为Anderson+1.0 mg/L ZT+ 0.1 mg/LNAA;生根培养基为Anderson+1.0 mg/L NAA;炼苗移栽基质以腐殖土∶珍珠岩=2∶1混合效果最好.     

Practical Method of High-Speed Access for Medical Digital Image Sequences

The high-speed access for medical digital image sequences was restricted to special device and complicated system in the past. The authors present a new method of high-speed access for medical digital image sequences which can be performed on general computer by means of the combination of Serial ATA(SATA) and Redundant Array of Independent Disk(RAID).Then they introduce the scheme of system configuration and software program. Lastly the testing result is given and the speediness,cheapness and conveniency of this method are elucidated.     

篦子三尖杉的扦插繁殖研究

对篦子三尖杉不同长度扦插穗条、不同植株部位插穗和插穗的浸泡处理进行对比试验结果表明:不同插穗长度对篦子三尖杉扦插成活率没有影响,不同部位插穗扦插成活率差异大,以上部和中部1级枝成活率最高,其次是上部2级枝,最低是中部3级枝和下部2、3级枝;不同浸泡处理中,篦子三尖杉扦插成活率没有显著差异,但不同处理中,ABT处理会促进多发根;不同枝条长度和不同处理方式对篦子三尖杉插穗发枝量没有显著影响,但不同植株部位插穗发枝量有差异,中上部一级枝发枝量多.
