一种不使用切片机的石蜡制片及其数码照片的光学信息解析(英文)

[Objective] The research aimed to study a paraffin method without using the microtome,and also introduced an analysis method for optical information of the plant anatomical digital photographs.[Method] The plant material softened or not was embedded in paraffin according to the paraffin method.Cut the thin paraffin sections from the paraffin block with a sharp two-sided blade under anatomical lens.The thin material sections rolled up when they were cut off.Took the section rolls to a slide,and then heated them to melt the paraffin section roll.When the paraffin melted,the sections of plant material were rolled out.After the common or simplified procedures of staining and mounting,the preparations were finished.When an anatomical digital photograph was processed,copy it into the word file and two copies of the original photograph were obtained.One copy was selected to make it to be a negative photograph,and then press the key ＂Press Screen＂ to copy the screen frame.After it was copied into the word file,cut of the unnecessary parts and other operations were carried out,then processed photograph was obtained.[Results] The anatomical preparation for research was gotten.The analyzed digital photograph of the leaf structure of Salix matsudana var.matsudana f.tortuosa has some a three-dimensional effect,and the different leaf structures and cells,e.g.cuticle,cell wall,protoplast,vein,etc.can be identified easily.[Conclusion]The paraffin method without using the microtome has advantages of low cost and higher efficiency,which could be applied by the beginner or in the time without a microtome to be used.The analysis of the plant anatomical digital photographs can acquire more structural information than the original digital photographs,which shows the potentiality and prospects of the optical information analysis of the microscopic imagery and its digital photograph.

[目的]研究一种不使用切片机的石蜡制片方法,同时提出一种对植物解剖学数码照片进行光学信息解析的方法。[方法]将材料包埋成蜡块,在解剖镜下对材料蜡块进行切片,将切下的薄蜡片卷转移到载玻片上加热,石蜡融化后便将切片展平,再经常规或简化的染色制片程序完成封片。对植物解剖学数码照片处理时,先将其拷入word文档,在文档中获得2份相同的照片,用鼠标选定(刷黑)其中一张,使其成为原照片的"负片",然后复制整个屏幕,将其粘贴到文档中,经剪切等操作后获得处理后的照片。[结果]获得了比较理想的植物解剖学制片。龙爪柳叶片结构的数码照片经过处理后,具有一定的立体感,其角质层和细胞壁等结构及细胞的识别更加容易。[结论]该方法成本低、效率较高,可供初学者或无切片机时使用。对解剖学数码照片进行光学信息解析,能获得普通数码照片无法显示的一些结构信息,显示出光学信息解析的潜力与前景。
