A broad expanse of the river was turned to blood; in the middle distance the red hue brightened into gold;,through which a solitary log came floating ,black and conspicuous; in one place ,a long slanting mark lay sparkling upon the water; in another the surface was broken by boiling ,tumbling rings, that were as many-tinted as an opal; where the ruddy flush was faintest ,was a smooth spot that was covered with graceful circles and radiating lines, ever so delicatedly traced; the shore on our left was densely wooded ,and the somber shadow that fell from this forest was broken in one place by a long, ruffled trail that shone like silver; and high above the forest wall a clean-stemmed dead tree waved a single leafy bough that glowed like a flame in the unobstructed splendor that was flowing from the sun. there were graceful curves ,reflected images ,woody heights ,soft distances ; and over the whole scene ,far and near ,the dissolving lights drifted steadily ,enriching it every passing moment with new marvels of coloring.

还记得自己刚开始船上生涯时所见过的那次辉煌的落日：宽阔的河面一片血红；不远处这红色明亮起来，变成金色，一根显眼的黑色圆森木从中漂过；这边，一根长长的浮标倾斜在水面上，熠熠闪光；那边，翻滚的波浪打破了宁静的水面，像猫眼石般色彩纷呈；微红的水流最缓和处，美丽的涟漪在平稳的水面上层层荡漾开去；左侧的河岸上丛林茂密；一条如银带般闪亮的小径从昏暗的树荫中蜿蜒而出，伸向远处；高高的密林之上有一根无枝无蔓的枯树，仅留有一根带叶的树枝在风中晃动，在太阳一泻千里的光辉里，它宛如燃烧的一团火；还有优美的波纹、水中的倒影、树木葱茏的高地、柔和的远景；放眼望去，由远及近，逐渐裉去的光线随波荡漾，每时每记得都以其新的奇妙着色为这条河添姿增彩。

The results showed that, NO-3-N contents and nitrate reductase activity had obvious diversity in different spinach varieties and different organs of the same plant. The NO-3-N contents in stem were the highest, followed by petioles, then mesophylls, and were the lowest in roots. When the ratio of root to shoot was higher, the NO-3-N contents in plants were lower. NR activity was higher in root especially in lateral root. The NO-3-N contents in mesophyll and petiole were negative correlated with the in vitro -NR activity and in vivo -NR activity in roots.

硝态氮含量以短缩茎中最高，叶和叶柄中次之，根中最低，且根/冠比越大的品种，其整体植株中的硝态氮含量越低；根尤其是侧根NR活性较高；叶肉和叶柄中硝态氮含量均与根中以内、外源硝酸盐为底物的NR活性呈一定的负相关。

Results Fascicles and certain amount (207) of motor fibers from the anterior division of C7 were distributed to musculocutaneous nerve and median nerve, the orientation of these fibers were not clear. The ones (323) from posterior division were to the axillary, radial, and dorsal thoracic nerves, thus the orientation of these fascicles was relatively definite.

结果 大鼠C7神经根前股发出一定数量的运动纤维到肌皮神经、正中神经，总量约207根，但在C7前股定位不明确；后股发出相应的运动纤维束支到桡神经、腋神经与胸背神经，总量约323根，这些束支在C7后股的定位较明确。C7神经根所支配的范围很广，其中以C7后股发出的胸背神经束支支配的背阔肌占比例最大（运动纤维含量＞50%）。

Results In healthy subjects, L2-L5 nerves were displayed clearly by MRN, with a round or ellipse ganglion of 3-6 mm in diameter, and smooth stick-like nerve root and trunk, 2-5 mm in diameter. The signal intensity was higher in ganglion than nerve root or trunk. 40% of nerve root sheath was surrounded by small amount of cerebrospinal fluid, Femoral nerve was displayed in all subjects, while only 83.3% of obturator nerve and 43.3% of lumbosacral trunk were manifested. Lamellar blurred hyper-signal intensity was seen around 80.9% of lumbar plexus in GBS, but none in CIDP.

结果 正常组MRN可清晰显示腰2~5神经的走行，神经节呈圆或椭圆形膨大，大小约为3~6mm，神经根及干呈条状、边缘光滑，大小约为2~5mm、神经节信号高于神经根和干，40%的神经根鞘有少量脑脊液，股神经、闭孔神经、腰骶干的显示率分别为100%、83.3%、43.3%。80.9%的GBS腰丛神经周围有片状模糊高信号，神经根和节大小和信号无明显改变，25%神经干增粗，50%的神经干信号增高，边缘模糊。
