空闲

Astronaut Takao Doi "threw a boomerang and saw it come back" during his free time on March 18 at the International Space Station .

太空人土井隆雄十八日利用空闲时间，在国际太空站「丢掷一支回力标并看著它折返」。

If totalization no longer has any meaning, it is not because the infinity of a field cannot be covered by a finite glance or a finite discourse, but because the nature of the field-that is, language and a finite language-excludes totalization.

替补性定量的这种分配——如果我们可以这么表达的话——为了使空闲的能指和它被用来瞄准的所指之间保持作为象征思维之前提条件的那种互补关系是绝对必要的。

It seems true....I guest I have to unclutter my mind and make things clear and healthy....

心里明明想着要充实地生活，却总是在偶尔空闲的时候呆呆地坐着什么也不愿意做。

However, most of them found it unintuitive that the camera always goes into the idle mode after releasing the shutter.

不过，多数人觉得在释放快门后相机总是进入空闲模式，这一点不太直观。

He sat cross-legged before his wife, his big hand idle, his expression unstirred.

他盘腿坐在妻子面前，两只大手空闲着，表情木然。

Some people would like to just unstrained while other people would like to apply the available spare time to see a few tourist spots or take a ski trip.

有些人想刚才unstrained ，而其他人想适用于现有的空闲时间看一些旅游景点或滑雪之旅。

In the meantime, Von Ahn has figured out a way to take advantage of all the spare brainpower hundreds of millions of people expend deciphering wiggly letters.

同时，Von Ahn想出一种利用数亿空闲脑力识别扭曲字母的方法。

Through simulation and computation, some critical values to contral interferences are obtained. These values have directive significance to the design and deployment of WRAN.(4) New methods to measure and analyze spectrum aredevelopedAccording to the shortages of previous spectrum measurements, new methods to measure spectrum occupancy in wide-band and multi-point synchronously is proposed in this dissertation, and the tests last a whole week; the relativities of licensed services are considered when test points are selected. More importantly, data mining and in-depth analysis are carried out with the huge amounts of test data, and a channel analysis method using Channel Vacancy Duration and Service Congestion Rate are proposed. The spectrum relativities of 3-dimension in time, space and frequency are researched also. The correlativity between channel state and history information is discoved, and which will provide the scientific basis to channel modeling, spectrum analysis and decision of CR users.

4提出了频谱测量与分析的新方法针对以前频谱测量工作存在的不足，本文提出了多点同时广域频谱测量方法，测量工作持续了一周的时间，同时考虑了测量地点的选取和频谱授权业务之间的相关性；对测量得到的海量数据进行了数据挖掘和深度分析，提出了使用信道空闲时间(Channel VacancyDuration，CVD)和业务拥塞率(Service Congestion Rate，SCR)进行信道分析的方法，研究了频谱之间的时间、空间、和频率三维立体的相关性，发现了信道状态和历史信息的关联性，为CR用户的信道建模、频谱分析和决策提供了科学的理论依据。

"It is allowing people to contribute their idle time that they wouldn't be doing for anything else," Zaman said.

&这可以使得人们将他自己的计算机原本荒废的空闲时间贡献出来&，Zaman如是说。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。
