In this paper, the anatomical identification of Linnaea borealis has been made. We presented the evidence that the plant has a good adaptaility to the environments in Changbai Mountains.Stem transvers show that the species can live in Changbai Mountains for many years.As one of the smallest bush plants in the world, it can resist the cold environment in Changbai Mountains, because it has special structures such as the special periderms, rays and pith.The cork in the thick periderms of roots and stems are made of big cube cells full of air. The cork cells play an important role in protecting the plant from heat. Many primary and secondary rays are observed in the secondary xylem. Each ray is made of one row parenchyma cells.The plant has bigger pith made of many bigger parenchyma's cells. The pith and ray cells can help the plant to store and transfuse the nutrient for growth.

本文对林奈木(Linnaea borealis L.)进行了解剖研究,证实林奈木系多年生小灌木,绝非半灌木。同时也弄清了该植物茎不能增粗和对高寒山区适应的原因。

The adventitious root developing from stem cuttings from black currant belongs to thedermal-rooting type.The adventitious root in var.‘Thick-Skin’is mainly clustered andlongitudinal,and in Var.′Thin-Skin′is mainly clustered and scattered.There are performedadventitious root primodia in the stem of black currant,and they are initiated fromparenchymatous tissue in pith ray or secondary ray near cambium.Rooting is influenced bythe structure of the stem and the content of nutrients in it.The content of carbohydrats andnitrogeneous compounds changes in a regular way during the period of rooting.Any part ofthe hardwood cutting in var.‘Thick -Skin’of black currant collected in Spring treated withNAA or IBA at 50 ppm for 1~5 min,the effect of rooting of the cutting was good in waterculture as well as in soil culture.the basal part of the softwood cutting in var.‘Thin-Skin’collected in Summer treated with NAA at 50 ppm for 1 min or 30 min,the effect of rooting ofthe cutting was also good,but water culture was better than soil culture.

黑穗醋栗属于皮部生根型。厚皮品种插条不定根的排列以簇生和纵生为主,薄皮品种以簇生和散生为主。解剖观察表明,黑穗醋栗具有先成不定根原基,起源于髓射线或次生射线与维管形成层交叉处。茎的结构及茎内营养物质含量均影响生根。生根期间全碳、全氮呈现规律性变化。厚皮品种硬枝各部位作插条,50 ppm NAA 或 IBA 处理1~5 min 生根较好,水培和土培方法均可采用;薄皮品种绿枝下部作插条,50 ppm NAA 处理1 min 或30 min 生根均较好,且以水培方法为宜。

Although X ray inspection TV has characteristic of saving on X ray soft film and online inspection. It still has the problem of low image resolving power. Secondary ray from X ray results in mainly reason which is a random noise jamming. In order to remove the noise jamming and heighten the image resolving power. A progressive average method in computer image processing is taken effectively. In addition, high speed message acguisition system of which image storage is made up of hardware is demanded for numeral of TV image with another window technigue. The cost of X ray inspection TV is low, it is a promising system and very important meaning to assure the guality of products.

X光探伤电视系统虽然具备节省X光软片和可在线探伤等优点以外,还存在着图像分辨率不很高的问题。其图像分辨率不很高的主要原因是由于X光所激发的二次射线造成的,这是一种随机的噪声干扰。利用在计算机图像处理中的叠加平均法可有效的去除这种噪声干扰,从而提高X光探伤电视的图像分辨率。电视图像的数字化需要高速的信号采集系统。用硬件构成的图像存贮体可实现高速的图像信号采集,并结合开窗口技术使得X光探伤电视的成本降低,为高分辨率X光探伤电视的广泛应用创造了有利的条件。这些对保证产品质量具有十分重要的意义。
