xylem ray 中文意思是什麼
xylem ray
解釋
木射線-
Thickness of upper and lower epidermis of leaves, width of xylem and phloem of annual and biennial branches, ratio of late wood to early wood, periderm thickness of biennial branches, and length of xylem ray present decreasing trends with latitude ascending ; while ratio of palisade tissue to spongy tissue, epidermis thickness of annual branches, and cortex thickness of biennial branches show unobvious variations with latitude increasing
葉的上下表皮厚度、 1和2年生枝木質部及韌皮部寬度、晚材早材比值、 2年生枝的周皮厚度、木射線長等均隨緯度升高而呈下降趨勢；而葉的柵欄組織和海綿組織比值、 1年生枝表皮厚度、 2年生皮層厚度等解剖結構隨緯度變化沒有明顯規律。 -
The secondary phloem parenchyma cells and secondary phloem ray parenchyma cells were the preferential sites for protein storage to the xylem parenchyma cells whereas a large amount of vegetative storage proteins was present in xylem, especially in the primary xylem and the inner secondary xylem of the extended stems
營養貯藏蛋白質優先在次生韌皮部的韌皮薄壁細胞和韌皮射線薄壁細胞中積累，在新梢伸長生長停止后，新梢基部莖的木質部中也積累了相當數量的營養貯藏蛋白質，主要分佈在初生木質部和內側次生木質部的各種生活的薄壁細胞中。 -
More anthraquinone compounds was distributed in pith ray cells and the tissues of mature stem suchas bundle sheaths in large - scale vascular bundle, primary phloem and primary xylem than that in young stem. [ conclusion ] the distribution of anthraquinone compounds in the stem was of multilocus
結果隨著莖的不斷成熟，在莖的表皮、近表皮的1 ~ 2層皮層細胞及較內部皮層中，不同程度地增加貯藏和積累了一定數量的蒽醌類化合物，成為莖外部貯藏和積累蒽醌共化合物的主要結構部位成熱莖大型維管束的維管束鞘、初生韌皮部、初生木質部等組織和髓射線細胞分佈了比幼莖多的蒽醌類化合物。 -
The research content is detect of log internal defect ( such as knobs, internal decay, hollow, etc. ) and shape by using x - ray to penetrate the log. the absorb of x - ray between log internal defect and log internal xylem is different. so the x - ray photograph is different. if we can get the several side x - ray photograph of log. and input the photograph into computer to digital image process
由於原木木質部分與內部缺陷部分對x射線的吸收能力不同，在x射線底片上形成的影像也不一樣，如果對檢測原木從不同的方向進行照射，再把得到的射線底片輸入至計算機內部進行處理，就可以得到原木內部的大致空間結構參數，對原木的加工有重要的輔助作用。
