Based on the experimental results, it could be consequentially concluded that N-methoxycarbonylation of aromatic amines was followed by the exclusive N-methylation of methyl N-aryl carbamates during the reaction process.

苯环上有钝化基团的一级芳胺反应活性比较好，获得N-甲基-N-芳基氨基甲酸甲酯的产率较高，反应时间也较短；而苯环上活化基团的存在，则会降低一级芳胺的反应活性。

The sand body thickness and sand grain of gas-producing horizon are lies on incumbent relation of different microfacies. The production has direct affiliation with porosity, permeability, porosity texture.

产气层段砂体在纵向上的厚度与砂岩粒度受控于不同微相在纵向上的叠置关系，产能的高低与储层的孔、渗条件和孔隙结构特征有更直接的联系。

The egg production of a week et al was also analyzed . 18 pairs of microsatellite primers were screened from chromosome 1 and chromosome Z, the primers were designed to allow optimal performance of the markers, in sets containing multiple microsatellites, on ABI3100 sequencers. We determined there were correlation among 13 microsatellite markers and 19 characters in 25 egg traits through least square means. At the same time, we calculated correlation among characters of egg traits in silkies.

从鸡1号染色体和Z染色体上筛选出18对微卫星标记，进行多重PCR扩增，并对引物组合的反应体系进行优化，在F1群体中检测到13个标记位点分别与25种性状中的19种性状有不同程度的相关，并进行同一标记不同基因型间的多重比较，同时还计算了产蛋性状间的表型相关。

河北滦县、蓟县、北京十三陵三个地方的常州沟组宇宙尘是在人工重砂的重矿物中发现的，产在古老沉积岩地层中的砾岩和砂岩里，大部分是铁质宇宙尘，形态各异，表面构造多种多样，内部构造各有不同，具Fe—Ni金属，核与壳的化学元素分布不匀匀，化学成分与深海宇宙尘相似。

Currently, worldwide more than 20 types of sturgeon fish, which,Only produced in the south of Russia and Iran to the north of the Caspian in the domain of the Beluga, Asetra, Sevruga three kinds of sturgeon eggs, which can be made into the precious caviar as we know it.

目前，全世界有超过20种类的鲟鱼，其中，只有产自俄罗斯以南及伊朗以北的里海海域中的Beluga、Asetra、Sevruga三种鲟鱼的卵，才能用以制作成我们所熟知的珍贵鱼子酱。

The spectroscopic properties (λ〓〓,λ〓〓,φ,τ, k〓, k〓) of 〓 were also measured. It was found that the energies of absorption and emission maximum is red-shifted for both electron-withdrawing and electron-donating substituents compared to that of parent 〓 complex.

发现无论X是吸电子取代基还是给电子取代基，配合物的吸收峰和发射峰与母体化合物〓相比均向红移；常温下，具有吸电子基的配合物与具有给电子基的配合物相比，有较高的发光量子产率和长的激发态寿命。
