At the surface of the pollen grains there are three types of aperturates, including three porates type, three colpates type and three porate - colpates type ; and four types of sculpture, namely, reticulate, striate, striate - reticulate and verrucate. the upper epidermal cells of the leaves of 12 species plants are detected with hpias - 1000 image analytic system through the treatment of binarization, and the experimental methods are proved stable. the results indicated that the waviness of the anticlinal walls ( sfc ) and the ratio of the feret ' s diameter ( slf ) of the epidermal cells of the middle lamina in the third node of leaves starting from the lowerest part of the stem have a relative constant range and could distinguish from each other. oieanolic acid, l, 5, 8 - trihydroxy - 3 - methoxyxanthone and swertiamarin are separately detected on the tlc, and the different chromatogram of various plants can be considered as characters of identification. the contents of oleanolic acid in 12 species of plants are determinated by hplc, but among the different plants and botanical organs their contents are different, and the highest content in flowers
本文對川鄂產獐牙菜屬藥用植物資源進行了野外調查、標本採集和鑒定，對12種乾燥藥材的性狀進行了描述，提供了可以鑒別的特徵。通過掃描電子顯微鏡觀察的12種本屬藥用植物的花粉粒均為單粒花粉，萌發孔有3孔型， 3溝型和3孔溝型三種類型；表面紋飾包括網狀紋，條狀?網狀紋，條狀紋和瘤狀紋四種類型。用hpias ? 1000高清晰度彩色病理圖文分析系統對葉片上表皮細胞作圖像分析，並進行方法學研究，結果表明，同種植物莖上第3節葉片中段主脈和第1側脈之間葉上表皮細胞垂周壁彎曲程度sfc值和細胞縱、橫向直徑的比值slf值，種間有顯著差異，每種都有相對恆定范圍值。The development of fieldbus and the protocol content of can are first presented in this paper, and the circumstance and performanceof real - time communication in modern industry control system are discussed. on a basis of the research founded by shaanxi project " design of smart electrical actuator based on fieldbus " and xi ' an project " design of intelligent measurement and control node based on can ", the following problems are studied : flexible control and real - time communication in modern factory automation ; the model and protocol in can circumstance, including several popular can highlayer protocol such as canopen, devicnet ; time trigger and event trigger schedule in can ; design of intelligent can node based on 80c51mcu
