在初始网格剖分上采取分段线性函数空间作为有限体积元方法的试探函数空间，在相应的对偶网格上采取分段常数函数空间作为其检验函数空间，对一维不可压缩两相渗流驱动问题提出了全离散有限体积元方法，并得到L2-模误差估计。

The sodium ions located in the 12-membered ring main channel (with Q〓〓0.2 MHz) of zeolite omega are fully hydrated and so mobile to average out the 〓H-〓Na dipolar interaction, while those in the gmelinite cage (Q〓=2.3 MHz) are less hydrated and closely bonded to the lattice oxygen.

3〓Na MAS及〓Na二维四极章动实验的研究表明，在NaΩ分子筛中存在两类不同水合状态的钠离子：一类处于12-圆环主孔道中(四极作用常数Qcc＝0.2MHz)，另一类处于菱钾沸石笼里(Qcc＝2.3MHz)。

The reactions of 〓with bptz generate a cyclic tetranuclear and a 1-D helical chain 〓 complexes with thehydrolysis reaction products: 2,5-di(4-pyridyl)-l,3,4-oxadiazole and N,N'-bis(α-hydroxyl-2-pyridyl)ketazine.

本文利用〓在不同的环境中与bptz反应得到两个水解产物形成的配合物并解析了其晶体结构，一个为一维链状配合物，另一个为一个四核环状结构。

The rest positions of 〓 unit are occupied by water and an oxygen atom of carboxylates from another type of ligand. With two carboxylates of this type of ligand, two ladderlike long chains are connected to form one-dimensional ladderlike chain structure.

In 1593 and 1594, when the theatres were closed because of plague, Shakespeare published two narrative poems on erotic themes, Venus and Adonis and The Rape of Lucrece.

在1593年和1594年，当剧院由于灾难关闭，莎士比亚发表了两篇以情欲为主题的短诗：维纳斯与阿多尼斯和柳克丽丝的侮辱。

Presaging the work of Charles David Keeling, which began two years later, Plass called for new accurate measurements of the increasing CO2 concentration in the atmosphere, which he rightly estimated should be on the order of 0.3 percent per year.

他呼吁科学家对大气中不断增高的CO2浓度进行新的准确测量，并正确地估计出了其增加速度应为每年0.3%，两年之后查尔斯·戴维·基林开始了这项工作。

I started on a retinoid, and my scars seemed to get worse for a while. This scared me and made me sick to my stomach. But then after 6-12 months they got better. Now, over two years later, you can hardly see my scars.

于是我开始使用类维A酸，初期，我脸上的疤痕看起来更明显了，这可把我吓得连胃口都不好了，但是过了6至12个月后，疤痕慢慢减轻，现在，两年过去了，我脸上的疤痕几乎看不见
