查询词典 D

Based on geomorphy and anthropo-factor that influence land use structure, D and S of 8 types is analyzed, and the result indicate that:(1) the complicated geomorphy is uppermost factor that influence fractal dimension of land use type;(2) the social economical level influence D and S of land use structure in a certain extent;(3) the average fractal dimension values and average stability indexes are integrative reflection of the land use structure of each region.

结果表明：(1)复杂的地貌类型是影响土地利用类型D 值和S值的最主要因素；(2)社会经济发展水平一定程度上影响土地利用类型的分维值和稳定性指数；(3)区域土地利用类型的平均分维值、稳定性指数的大小是土地利用结构的综合反映。

If the ratio or the concentration of 2, 4-D was higher, the callus formed quickly, but it was hygrophanous, and easy to necrosis, conversely, if the ratio or the concentration of 2, 4-D was lower, the callus appeared very slowly or could not form, and adventitious root formed directly or indirectly.

比值较高（或2，4-D浓度较高）时愈伤组织出现的时间较早，但愈伤色泽不好，呈半透明水渍状，易于褐化死亡，而比值较低时，愈伤出现得很慢或不形成愈伤，且易于直接或再分化形成不定根；这些不定根长至1.5-2.0cm时就不生长，并逐渐褐化。

Activation of NF-κB(p65) with evident nuclear translocation was found in neonatal rat NEC model. The pathological lesions indicated that intestinal tissue necrosis in varying degrees in group C and D, which were 2-4 points, but obviously lessened in group E, which were 0-2 points. Conclusions Intestinal inflammation is ameliorated after the ITF is injected hypodermically.

结果 C、D组组织中NF-κB(p65)阳性表达较A、B及E组显著升高P(下标 a.01，E组与A、B组比较也有升高P(下标 a.01，且随NF-κB(p65)的激活有明显的核转移；病理切片示C、D组HE染色见肠壁损伤轻重不一，可见全肠黏膜绒毛坏死，病理评分2~4分；E组轻度肠上皮细胞脱落，顶端绒毛坏死，肠组织病理评分0~2分。

We successfully achieved the first synthesis of the core structure of Dragmacidin D---3,6-bis(3'-indolyl)-2(1H)pyrazinone.

首次成功地完成了Dragmacidin D分子骨架---3，6-双(3'-吲哚)-2(1H)吡嗪酮的构建，目前我们正在将这种方法用于Dragmacidin D的全合成工作。

METHODS: Thirty six SD female rats were randomly separated into 3 groups (n=12 in each one) according to the infarction duration (1, 3, 28 d), which were randomly and evenly again separated into 2 subgroups: operated group and sham operated group. The levels of mRNA expression of ACE2 in the noninfarct and infract area of left ventricle 1, 3, 28 d after AMI were detected by RT PCR and analyzed semi quantitatively by image analysis system.

将36只SD雌性大鼠按时间段随机分为3组（每组12只），每组再随机分为假手术组、手术组2个亚组（每组6只），应用RT PCR方法检测大鼠AMI后1，3，28 d左心室梗死区及非梗死区心肌ACE2 mRNA的表达，并以图像分析系统对其进行半定量分析。
