網眼密度 的英文怎麼說
中文拼音 [wǎngyǎnmìdù]
網眼密度
英文
reticular density-
An ommatidium is composed of cornea, two corneagenous cells, four cone cells, eight retinular cells, rhabdom, distal pigment cells, distal and proximal reflecting pigment cells, in blue, red and in full bright light conditions, compound eyes exhibit obvious characters the disarrangement of microvilli in the rhabdom, the increased number of lamellar bodies, distal and proximal pigment granules covering the crystalline cone and rhabdom to prevent hard light damaging the ommatidia
現將我們的研究結果報道如下：日本沼蝦復眼屬于反射型重疊像眼，每一小眼由角膜，成角膜細胞（ 2個） ，晶錐細胞（ 4個） ，小網膜細胞（ 8個）及其形成的感桿束和遠端色素細胞、遠端反光色素細胞、近端反光色素細胞組成。小眼角膜長方形，小眼密度為512個mm ~ 2 。Besides, we give another conservative remapping algorithm in allusion to the difficulty of integrating the known density distribution in the old mesh over the cell volume. the new mesh is subdivided in order to calculate the densities of new smaller meshes. then densities of the new mesh are known accordingly and high accuracy remapping is finished
本文首先用蔡慶東提出的重映方法，編制了相應的程序，然後給出了另一種重映方法，即對於一般的密度分佈，針對重映積分計算的困難，將新網格進行了細劃，先確定新網格小網眼中心點的密度，將小網眼的質量直接計算出來，再計算新網格的質量，然後確定相應的密度，從而實現高精度重映。There have been a mass of research documents showing that many visual functions deteriorate with age both for human beings and for animals. age - related visual function decline could not be completely attributed to optical and retinal changes. considerable visual impairments in the old might result from morphological ( such as cell loss, dendritic change and synaptic density decrease ) or functional ( such as weakened gaba inhibition ) degeneration of visual pathways. in this article we made preliminary studies on the mechnisam underlying visual function degradation by electrophysiological and morphological methods
隨著年齡的增長，人及動物的許多視覺功能出現衰退，老年性視覺能力降低並非完全由眼的光學因素和視網膜形態、功能變化導致，不少方面可能決定於衰老引起的視覺中樞結構（如神經元丟失、樹突野改變及突觸密度下降等）和生理功能（如皮層內gaba能抑制作用減弱等）的改變。
