可用空间

There has been a great deal of speculation over the zerg choice to occupy Char, given its harsh environment and total lack of any organic life forms to exploit. Theorists are evenly split among the ideas that Char forms a useful jump-off point to the core worlds of terran and protoss space, that its inhospitable nature makes it easier for the zerg to defend it, or that Char\'s high radiation levels promote an increased rate of mutation in zerg organisms to enable forced evolution of specialist strains.

在虫族占据 Char 期间有大量的投机活动，鉴于有害的环境和缺乏有机生命形势的利用，理论家们用均匀分裂的方法在 Char 形成了一个可用的进入人类世界和神族空间的跳跃点， Char 荒凉的自然性质更利于虫族的防守，甚至 Char 的高度放射性等级促进了虫族机体组织的变异使其演变出特殊的种类。

Vertical NAD distributions could be well-fitted by β function and the two-dimennsional NAD distribution by the trend surface equation of relative crown height and relative crown radius.

NAD的水平和垂直分布均可用β分布函数表达，而相对冠高和冠径的二次趋势面表达式可很好地描述NAD二维空间分布。

Until quite recently, the only useable catalogue for CCD observers was the Hubble Space Telescope's Guide Star Catalogue, that contains about 18 million objects.

直到目前，对于CCD观测者唯一合适可用的星表是GSC（哈勃空间望远镜的引导星参考星表），它包含1.8亿个目标。

The pipelined CORDIC architecture is very suitable for FFT butterfly operation because of its high throughput and regularity, but it will consume lots of resources,this article presents an improved architecture of CORDIC pipeline,starting with the property that the FFT rotary factor is fixed but not arbitrary,and according to the mapping between the basic rotational angle of CORDIC and scale factor and the rule for transform among the scale factors.On the condition that the velocity of FFT butterfly operati...

CORDIC流水线结构因其高吞吐率及规整性，而很适合于FFT蝶形运算，但其缺点是耗资源多，本文从FFT中旋转因子固定不任意的特点出发，根据CORDIC基本旋转角度与缩放因子的对应关系和缩放因子之间的转换规律，对CORDIC流水线结构进行了改进，在蝶形运算速度不变的情况下，进一步减少所耗资源，在字长为16位的FFT中，每个旋转因子可用25位的控制序列来替代，从而使每个旋转因子的存储空间由32位减少到25位。

A typical PC owner might see the system as a barter economy in which he gets free services, such as file backup and Web hosting, in exchange for the use of his otherwise idle processor time and disk space.

一般个人电脑的所有者可能会将这个系统视为以物易物的经济架构，可用閒置的处理器时间和硬碟空间换取免费的服务，像是档案备份以及网站代管。

The principle of figure-ground segregation is one of the basic cognitive principles according to which space is organized, but it can be applied to literary works, especially the poetic images as well, and it thus becomes a basic cognitive principle by which images are organized in poems.

图形-背景分离原则虽是空间组织的一个基本认知原则，但也可用来研究文学作品，尤其是诗歌意象，因而也是诗歌中意象组织的一个基本认知原则。

Chrysanthemum of 10 thousand birthday is lax to edaphic requirement, with the arenaceous qualitative loam with fecund, good drainage had better.

万寿菊对土壤要求不严，以肥沃。排水良好的砂质壤土为好。

He unstepped the mast and furled the sail and tied it.

他拔下桅杆，把帆卷起，系住。
