In comparison with the observations derived from NOAA AVHRR, under the framework of NCAR CLM3, SCF schemes like CLM3 default, Douville1995, and Roesch 2001 underestimate SCF over vast areas, snow lines simulated in these three schemes are located to the south of that in the AVHRR observation, especially in autumn when snow pack begins to establish; Wu2004 scheme also underestimates SCF in the Eurasian continent in autumn; Yang1997 scheme slightly overestimates SCF, especially along the southern border of the snow covered area; Niu2007 scheme which accounts for the seasonal variation of snow density overcomes the positive bias of SCF simulated by Yang1997 scheme to some extent.

结果表明，在NCAR CLM3的物理过程框架之下，CLM3、Douville1995、Roesch2001三种方案低估了广大地区的积雪覆盖率，模拟的雪线位置偏北，尤其是在秋季积雪初期；Wu2004方案低估了秋季欧亚大陆的积雪覆盖率；Yang1997方案模拟的积雪覆盖率有些偏高，尤其是在积雪覆盖区的南部边缘；考虑积雪密度变化的Niu2007方案一定程度上克服了Yang1997方案的正偏差。

In comparison with court trials, administrative adjudications generally are governed by liberal evidentiary rules that create a strong presumption in favor of admitting questionable or challenged evidence.

和法院审判相比较，行政裁断一般受自由的证据规则支配。依此规则，常常造成很强烈的足以接受可疑的或受到质疑的证据的推定。

In comparison with general tiger's-eye stone, its w/w(Fe 2O 3+FeO) adds from 018 to 022, there is not abnormal reaction under Chelsea color filter , it appears as dark green color. So it can be preliminarily decided that its color is caused by Fe 2+.

从w /w (Fe2 O3+FeO)值来看，常见的黄色虎睛石为 0 1 8，绿色虎睛石为 0 2 2 ，结合样品在滤色镜下无异常反应和样品呈暗绿色的特点，可初步判断其颜色由Fe2 +所致。

Measurement of blood concentration of indocyanine green by pulse dye densitometry—Comparison with the conventional spectrophotometric method.

肝脏的实质性肿瘤富有结构和功能上非正常的血管网[12]，这将导致肿瘤组织内的血流动力学改变；据此推想，这可能是肝脏实质性肿瘤相对于正常肝组织清除ICG较慢的原因[13，14]。

By comparison of long-term exposure with long-term immersion, the release amount of ammonium, nitrite, nitrate and dissolved phosphorus into the overlying waters from the sediments were increased during the reflooding after long-term dessication, reflecting that long-term exposure stimulated sediments as a releasing source of nutrient and accelerated the biogeochemical cycle of nutrient in the tidal flat ecosystem.

通过对比分析发现，长期暴露之后能够增加沉积物向上覆水体释放NH〓-N、NO〓-N、NO〓-N和TDP，显示了长期暴露加剧了沉积物作为营养盐的源效应，并且加速了潮滩生态系统内营养盐的生物地球化学循环过程。
