jCarousel的大多数默认选项是合适的,所以这个散列只包含一个键-值对:scroll,值为1,这让 jCarousel每次只显示一个图像。
Most of jCarousel's default options are fine, so your hash contains only one key-value pair: scroll, with a value of 1, which tells jCarousel to display only one image at a time.
代码中发出对CITIES表的查询,以返回 APP.CITIES 表的 city_name、country和airport列中所包含的值。
The query is issued against the CITIES table to return the values contained in the city_name, country, and airport columns of the APP.CITIES table.
使用DPF,我们建议通过对pdb_id列的值进行散列处理来跨数据库分区分布pdbxml表和atom_site表中的数据。
Using the DPF, we recommend to distribute the data in the PDBXML table and atom_site table across the database partitions by hashing on the values of the pdb_id column.
非重复散列将使用工作表,因此可以提供不敏感的语义或对值敏感的语义。
The hash distinct uses a work table, and as such can provide insensitive or value sensitive semantics.
交叉表查询可对值进行汇总,然后按两组依据对它们分组:一组沿侧面排列(行标题),另一组沿顶端排列(列标题)。
Crosstab queries summarize your values and then group them by two sets of facts - one set down the side (row headings), and the other across the top (column headings).
并提出对给定的凸而单调的型值点列判断这种保形插值存在性的算法。
An algorithm is presented which determines if there exists such a shape preserving interpolation for convex and increasing data points given.
