Primary spectrum pyrometry based on radiation measurement within a finite solid angle

Abstract: The true surface temperature for an object can be determined by measuring emitted radiation. Primary spectrum pyrometry should be generally carried out by radiation measurement within an infinitesimal solid angle or within a finite solid angle in the case of diffuse emission, so that the radiation thermometry equations become a closed system for temperature and other undetermined parameters. The radiation thermometry equation with linear emissivity model is obtained, which can be used to measure the temperature of the object with non-diffuse emission within a finite solid angle. This equation is universal in radiation measurement, based on which equations for primary spectrum pyrometry are deduced. These equations are also universal in radiation measurement, in which the emissivity scales under different measurement conditions are limited to the same range, but have different physical meanings.

Abstract: A primary observation on the DNA, RNA, basic protein, acid protein and polysaccharide at the process of fertilization in the proembryo and early young embryo of Keteleeria evelyniana Mast has been made through histochemical methods. The following results are obtained:The DNA staining reaction was weaker by using Feulgen reation before and after fertilization within the egg nucleus. After formed proembryo and early young embryo, the content of DNA in the nuclei of the initials became normal. The RNA and acid protein contents are rich during the whole development, especially within the embryo initials. However, A-S staining of the basic protein was negative within the neocytoplasm, but the DNA, RNA, acid protein and polysaccharide were positive.

Abstract: 在炉内喷钙尾部增湿活化(LIFAC)脱硫后的低温高湿烟气中添加适量蒸汽建立蒸汽相变所需的过饱和环境,促进水汽在细颗粒物表面凝结,进而由高效除雾器脱除凝结长大的含尘液滴。采用电称低压冲击器(ELPI)实时测定细颗粒物数量浓度及粒径分布,维萨拉温湿度变送器测试烟气温度和湿度。考察了活化水添加量、蒸汽添加量、细颗粒物数量浓度及除雾器性能对应用蒸汽相变促进细颗粒物脱除的影响。结果表明,在经LIFAC脱硫后的低温高湿烟气中添加蒸汽,烟气过饱和度随蒸汽添加量的增加先增后降;应用蒸汽相变可有效促进细颗粒物脱除,其促进作用随烟气过饱和度的升高、颗粒物数量浓度的减小和除雾器效率的提高而增强。

Abstract: 以燃煤锅炉产生的含尘热烟气为对象,针对石灰石–石膏法湿法烟气脱硫(wetfluegasdesulfurization,WFGD)工艺,采用Vaisala-HMT337型温湿度变送器等测试仪器,考察了脱硫操作条件对脱硫净烟气温湿度的影响规律;借助MATALBA软件计算分析了脱硫净烟气与蒸汽在脱硫塔顶部的相变室内混合过程中过饱和水气环境的形成规律。研究结果表明:脱硫塔出口净烟气相对湿度随液气比和脱硫浆液温度的增大而提高,净烟气温度随液气比的增大而降低、随浆液温度的升高而升高;添加蒸汽后混合烟气的过饱和度随脱硫净烟气相对湿度和蒸汽添加量的增加而增大,随脱硫净化烟气温度的升高而减小。通过优化脱硫操作条件辅以添加适量蒸汽,可以在脱硫塔顶部的相变室建立细颗粒物凝结长大所需的过饱和水气环境,促进细颗粒物核化凝结长大并脱除。

山珊瑚内生菌根的研究

Abstract: 山珊瑚内生菌根真菌在人工培养基上分离培养不能生长。侵染菌丝由山珊瑚侧根表皮侵入,在皮层中部形成侵染通道。进入皮层细胞后形成丛枝吸器。被侵染的寄主细胞仍是生活细胞,但细胞质变稀,蛋白质、RNA含量很少。近中柱的6至8层皮层细胞壁增厚并木质化。丛枝吸器含有丰富的红淀粉,少量的中性脂肪、碱性蛋白质和D NA。菌丝丛枝干幼龄期电子致密,周围有界面物质包围,在衰老时泡囊化,界面物质亦瓦解。吸器由五边形结构组成。寄主细胞在被侵染前含淀粉质体、线粒体、高尔基体、内质网和核糖体,在被侵染后,淀粉质体消失,其它细胞器数量明显减少,而主要是微丝和小液泡及多泡体。文章讨论了山珊瑚菌根与天麻和泡囊-丛枝菌根的异同。

Edge detection algorithm for SAR image based on improved ROEWA
基于改进ROEWA算子的SAR图像边缘检测方法

Abstract: Ratio of exponentially weighted average (ROEWA) operator is an multi-edge detector suitable for SAR images. The detector which is unable to compute the edge direction, cannot get the exact edge position. The reasons for these problems are analyzed and the flow chart of edge detection is modified in this paper. The constant false alarm rate (CFAR) character is retained by the traditional operator and the accuracy of non maxima suppression (NMS) is improved by the difference operator. Then Radon transform is carried out to get the edge direction for its excellent geometrical analysis and noise immunity properties, and by this way, the line connection is facilitated. The experiment results based on the SAR images show that the performance of the improved algorithm is robust and efficient.

Abstract: Distribution of endophytic bacteria was observed within the tissue and cells of bulb, roots, stem, leaves and floral bud of lily, but the number of bacteria is different. The number of bacteria is highest within the bulb cells of lily. It my-be relating to the content of nutriment. The number of the bacteria within the cells of outside scale is higher than that inside. In the bulb of lily the bacteria within the meristematic cells of growing tip are less or without, but there are more in the mature cells of base. Within the epidermis cells of outside scale, numerous tube-lick structures which appear to arbuscules as infection line is shown in the most outside layer of lily bulb. These structures associated with cell wall, it is possible for an infection passage of the bacteria from soil. In our inference, the bacteria within the cells is no endophyte, because the propagation of the bacteria can distribute from mature cells containing bacteria into the meristematic cells following the development. The propagational way of the bacteria passed through is a pore of plasmodesma between pit-pair on the wall. After the microtubele of the plasmodesma is damaged, the bacteria goes from one cell into another cell following cytoplasm.
