查询词典 lumen-hour

Curvilinear calcification suggests an aneurysm but is a less specific finding because it can also occur in craniopharyngiomas and sphenoidal masses. The intense enhancement of the residual lumen is relatively specific, but differentiation from other masses may be difficult on CT scans depending on the timing and degree of vascular enhancement. The MR imaging features are usually diagnostic, although they can be very subtle [2]. Significant signal heterogeneity is seen with T1 hyperintense signal due to subacute thrombus or flow related enhancement. Areas of T2 hypointensity can be seen due to intracellular deoxy or methemoglobin, calcification, or flow void.

线样钙化提示动脉瘤，但不是一个非常特异的征像，因为这也可以见于颅咽管瘤和蝶骨肿瘤，管腔样明显强化更特异些，但是在CT上与其他肿瘤鉴别可能是困难的，因为这取决与增强的时间与血管强化的程度，MR的特征性表现是更具有诊断意义的，即使有时候可能表现的非常细微，在T1上可以看到明显的不同信号成分，这是由于亚急性的血栓或流动相关增强效应，T2序列上可以看到低信号区域，这是由于细胞内脱氧或高铁血红蛋白，钙化，或流空效应。

用透射电镜对枣粘虫雄蛾触角感器的超微结构进行了观察，结果表明，每个毛形感器是由几丁质表皮毛及位于其下的三个感觉神经细胞构成，几丁质表皮毛上有许多孔与外界相通，毛腔内充满感受器淋巴液。

In this paper, chemistry composition, fiber morphology and pulping property in Solidago canadensis were analyzed and determined preliminarily. The results showed that the content of holocellulose was 81.86%, the content of cellulose was 42.63%, the content of lignin was 18.86%, it is feasible for using Solidago canadensis pulping based on it's chemical composition. The ratio of fiber length to width in Solidago canadensis was 36.67, the average length of fiber was 440 μm, and the length of fiber was too short to pulping. The ratio of wall thickness of fiber cell to lumen diameter was 0.34, and it was smaller than that of other woody fiber. In this experiment, four different methods of pulping were as follows: kraft-AQ pulping Ⅰ, kraft-AQ pulping Ⅱ, alkaline pulping, alkaline sulfite adding AQ pulping, but it was difficult for lignin removal in Solidago canadensis.

通过对一枝黄花的化学组成、纤维形态以及制浆性能进行初步探索，结果表明：(1)加拿大一枝黄花的综纤维素含量为81.86%，硝酸乙醇纤维素含量42.63%，木素含量18.86%，由化学组成看，加拿大一枝黄花是比较适宜制浆造纸的；(2)加拿大一枝黄花纤维的长宽比为36.67，纤维平均长度为44μm，从纤维长度来看，加拿大一枝黄花的纤维较短，不适宜制浆，其纤维壁腔比0.34，和其它速生材相比较小；(3)采用4种碱法制浆方案，硫酸盐蒽醌法Ⅰ，硫酸盐蒽醌法Ⅱ、烧碱法、碱性亚钠＋蒽醌法，结果显示，加拿大一枝黄花的木素非常难脱除。
