Experimental methods: pathological slices: To observe the changes of pathomorphology and measure the circular area of internal elastic lamina , area of neonate intima and vascular lumen, the intimal proliferatory index and percentage, the index of lumen stenosis and positive index of proliferating cell nuclear antigen through the specimens stained by HE and immunohistochemistry.

实验方法：病理切片：进行HE染色和免疫组织化学染色，分别观察病理形态学改变；测定和计算受损血管内弹力膜环绕总面积、新生内膜面积、管腔面积、内膜增生指数、内膜增生百分比、管腔狭窄指数和增殖细胞核抗原阳性指数；观察MMP-2、MMP-3、TIMP-1和PDGF-BB的免疫组化表达。

Under the scanning electron microscope , for the first time we compare and study both the coalified tracheids through chemical maceration and permineralized tracheid lumen casts. This method reveals the microstructures of wall and perforations of G-type tracheids: 1 The lignified layer of secondary wall is composed of uneven material and further divided into S〓, S〓, S〓 layers; with the smooth enclosing wall, the perforation is internally dumbbell-shaped; 2 In Huia gracilis, the enclosing wall of tracheidal perforation contracts and possesses secondary perforations. The perforation has thickened border facing the tracheid lumen.

本文首次在扫描电子显微镜下对比研究经化学浸解获得的碳质管胞和矿化的管胞腔铸体，明确揭示出了G-型管胞壁层和穿孔的显微结构：1）Hsüa reflexa次生壁木质化层的组成不均一，分为S〓、S〓和S〓层；穿孔腔为哑铃形，腔壁光滑；2）Huia gracilis的穿孔腔收缩，腔壁上发育次级穿孔，孔口具有边缘加厚。

The septum (34) is further preferably configured to minimize or eliminate the negative pressure deflection normally associated with the withdrawal of the large diameter luer cannula (32) from an enclosed fluid filled lumen or chamber, by substantially isolating the lumen or chamber from the septum material displacement resultant from luer (30)insertion.

上述隔垫(34)的结构最好设计成能通过把空腔或腔室与因路厄氏连接器(30)插入后所造成的隔垫材料的移动隔离开来，以便减小或消除通常与大直径的路厄氏套管(32)的抽出联系在一起的，因负压而引起的变形。

lumen：流明

这款 Pelican 7060 手电筒,重量不到旧式警用手电筒的一半,具备两段式开关、防滑手把,手电筒前端装有散热片,130 流明(lumen)的 LED 光束,足够让不合作的嫌犯短暂失去视觉,听起来那些被警察们追著跑的疑犯们似乎可以松口气,

lumen：腔

叶绿体蛋白需要控制穿越二层膜. 这些蛋白穿过外被的外膜和内膜进入基质(stroma),此过程与蛋白质越膜转运到线粒体的基质(matrix)的情况相同. 但有的蛋白还要进一步穿越类囊膜(thylakoid membrane)进入腔(lumen)中. 定位于类囊膜或腔中的蛋白转运途中必须经过基质.

lumen：内腔

在显微镜下观察,每一个年轮内具有两种类型的细胞,其中内侧(靠近髓心)部分乃由内腔(lumen)较大,细胞壁(cell wall)较薄且呈方形的细胞所集合而成,由於这类细胞是在春季生长期所形成的,因此又可称之为早材(early wood)或春材(spring wood)(图示).

lumen：管腔

1.3 血管壁面积测量 双侧颈动脉各选择3层(颈动脉分叉层面、分叉上和下各4 mm距离层面)测量管腔(lumen)、血管壁外界(outer wall boundary,OWB)和血管壁(wall)的面积,共288层(24例患者×2次扫描×3层×2侧).

lumen second：流明秒

lumen-hour 流明小时流明-小时 | lumen-second 流明秒 | lumenmeter 流明计
