查询词典 aster

The absorption spectrum center wavelength of dolomite is near 232 μm is shorter than 235 μm of limestone,and thus RBD7 and RBD8 can be employed effectively to identify dolomite and limestone,respectively. Felsic rocks show AlOH and Fe3+ absorption characteristics in the VNIRSWIR region,while the maficultramafic rocks show Fe2+ and Fe,MgOH absorption features,hence the use of different valence state of iron and secondary minerals can distinguish them:ASTER band2/band1 represent Fe3+ distribution,ASTER band2/band1 represent the Fe2+ distribution,RBD6 can estimate the AlOH mineral abundance. Psammitic/pelitic schist containing phengite,chlorite,stilpnomelane,as well as the weathered surface covered by clay minerals,exist characteristic absorption spectrum in the 221 μm(band 6),and has a high reflectance in 165 μm(band 4),while the blueschist/greenschist show high reflectance in the 221 μm(band 6),and it exit low reflectance in 165 μm(band 4),and blueschist/greenschist appear low ASTER band4/band6 ratio.

白云岩的CO2-3吸收谱带中心波长位于232〖KG*3〗μm，与灰岩的CO2-3 吸收谱带中心波长位置235 μm相比，具有向短波长方向移动的特点，据此可以利用RBD7、RBD8分别有效的识别白云岩和灰岩；长英质岩石显示AlOH和Fe3+ VNIRSWIR吸收特征，而基性超基性岩石显示Fe2+和Fe、MgOH特征，利用不同的铁价态和次要矿物可以区分它们：ASTER band2/band1代表了含Fe3+矿物分布信息、ASTER band5/band4代表了含Fe2+矿物分布信息、RBD6可以估计AlOH矿物的丰度；砂质/泥质片岩含较多的多硅白云母、绿泥石、黑硬绿泥石以及风化后表面覆盖的其它粘土矿物，在221 μm（band 6）存在有特征的吸收谱带，并且在165 μm（band 4）具有较高的反射率，而蓝片/绿片岩在221 μm（band 6）反射率较高，不具有明显特征吸收谱带，同时其在165 μm（band 4）反射率较低，因此蓝片/绿片岩ASTER band4/band6 比值低。

"Aster any of various plants of the genus aster in the composite family, having radiate flower heads with white, pink , or violet rays and a usually yellow disk."

Based on Phylogenetic analysis of sequences from these 10 phytoplasmas using PAUP (phylogenetic analysis using parsimony) software, these phytoplasmas could be classified into five groups. These phytoplasmas groups and strains were: group 1, sweetpotato witches' broom, mainland China strain of sweetpotato witches' broom, peanut witches' broom and Ipomoea obscura witches' broom; group 2, loofah witches' broom; group 3, elm yellows; group 4, rice yellow dwarf and sugarcane white leaf disease; group 5, New Jersey strain of aster yellows and western strain of aster yellows.

从spacer序列堆衍的亲缘演化树显示这10种植物菌质体可分为5群：第一群，甘薯簇叶病、甘薯簇叶病、花生簇叶病及细花牵牛簇叶病等菌质体；第二群，丝瓜簇叶病菌质体；第三群，榆树黄化病菌质体；第四群，水稻黄萎病及甘蔗白叶病菌质体；第五群，翠菊黄化病菌质体。

I love them all, even the double 'Waterlily'- but my favourite is Colchicum autumnale 'Album', and I team it up with Aster diviricatus, the wiry prostrate growth of the aster covering nicely during the summer when the colchicum foliage becomes dormant.

我喜欢所有的水仙，甚至包括重瓣的"莲花"——但是我最喜欢的是秋水仙"阿尔本"，我将它们与雏菊分开排成队列，整个夏天雏菊坚韧地匍匐成长着，对水仙作了很好的掩盖，而水仙的叶丛则处于睡眠状态。

Comparing the nucleotide sequences of 16S rRNA gene and ribosomal protein gene, we could find that these two strains have the highest homology of 99.4% and 99.8%, respectively. The nucleotide sequences of 16S rRNA gene for the CWB-YN strain shared higher homology (98.5%,98.9% and 98.0%) with phytoplasma strains in Tomato big bug 16SrI-A group, Western aster yellow (16SrI-B group and Clover phyllody (16SrI-C group). But it is obviously under 97.0% with other phytoplasma groups. The CWB-GZh strain shared higher homology (98.7%,99.1% and 98.3%) with phytoplasma strains in Tomato big bug(16SrI-A group ),Western aster yellow (16SrI-B group) and Clover phyllody (16SrI-C group).
