两倍的

Then formaldehyde attenuation curve which purification products reduce 5~10 times formaldehyde were tested, which has been tested at 1 m^3 environment deck according to experiment condition of eliminator standard GB/T18801-2002. Moreover, purification quantity per hour was computed by mathematics line integral surface. Results: The purification quantity which formaldehyde has been purificated by kieselguhr material was 1.44 mg/m^2h.

本研究选用了硅藻土和光催化两种原理空气净化材料，以室内空气常见的污染物甲醛为目标，参照国家空气净化器标准(GB/T18801-2002)中的实验条件，在1立方公尺环境测试舱内分别发生室内空气质量标准10倍的甲醛气体，测试净化产品对甲醛衰减曲线，运用数学曲线积分面积的计算模式来计算单位时间净化量。

This new BotArmy, named "Kraken," is twice as big as Storm, with over 400,000 distinct victims observed daily as compared to Storm's 200,000 victims.

这个被命名为"Kraken"的新的僵尸网络队伍，每天拥有超过400，000台受感染电脑，是有200，000台受感染电脑的Storm僵尸网络的两倍大。

BC's mountain pine beetles have thus far nested in an area nearly twice the size of the United Kingdom, killing some 500 million cubic metres of lodgepole pine — enough timber to build a modest-sized house for every person in Western Canada.

不列颠哥伦比亚省山地松树甲虫迄今在一个面积近两倍，英国的大小嵌套，造成约500亿立方米，松树，长满-足够的木材建立一个中等大小的每个人在加拿大西部的房子。

With its new terminal, the currently overtaxed Beijing airport should be able to handle some 90 million passengers yearly by 2012 -- more people than the population of France -- and well over twice its current capacity of about 35 million.

首都机场目前已经不堪重负，而有了新的航站楼以后，到2012年首都机场每年可承受的旅客吞吐量将达到9，000万人次左右──比法国的人口还多，是其目前3，500万人次的两倍多。

Though sensible, this system broke down in practice as every state firm—after several rounds of consolidation, there are still 169,000 today—haggled over the precise share of earnings it could retain. China's 1994 tax reform cleared all that up, by setting a non-negotiable corporate tax rate (now around 33%, about double that for foreign firms). In return, companies could keep all their post-tax profits.

尽管当时较为可行，但由于国有企业（经过几轮合并，今天仍有169000家国有企业）在保留多少利润的问题上争论不休，最终导致这个政策的流产。1994年的税制改革通过设置了一个硬性的所得税率（今天大约为33%，两倍于外商投资企业）对这一些进行了整顿，企业缴纳完应交税金后可以保留全部利润。

Given the same number of bits, unsigned integers usually represent twice the number of absolute values representable by signed integers.

给予相同的位元，无号整数通常能表示由有号整数所代表的值的绝对值的两倍数目。

Greg Ridgeway of RAND, a think-tank, points out that Los Angeles, San Diego and Pittsburgh pay their cops double the New York rate but are also having recruiting problems; the value of the NYPD brand, he adds, should not be underestimated.

来自兰德智囊团的葛雷格·里奇伟指出，洛杉矶、圣地亚哥和匹兹堡的警察薪酬是纽约的两倍，但同样遭遇了纳新问题。他补充说道，不要低估纽约警察这个称号本身的价值。

The behavior of most of the multibyte-character routines in the run-time library depends on the current multibyte code page setting.

对于可使用单字节代码页的系统，Unicode 数据需要的存储空间是非 Unicode 字符数据的两倍，但却消除了在代码页间转换扩展字符的必要，因此至少部分弥补了上面的不足。

While not quite as solid and detailed as what the solid-state and twice-the-price Bel Canto REF1000s can provide, the cacophony of bass was satisfyingly presented.

虽然A88T的声音并没有两倍价格的Bel Canto REF 1000s 晶体管机那样扎实和有细节，后者能够把低音中的杂音很好的展示出来。

Back in the early 1980s, the three network news broadcasters shared a combined audience of around 60m for their nightly shows, more than twice the current figure, and provided a shared experience for American families – a "nightly national seance" in the words of one contemporary.

追溯到上世纪80年代早期，美国三大新闻广播网晚间节目的观众人数合计约6000万人，是目前的两倍多，成为了美国家庭的一个共有体验——当时那一代美国人所说的"每晚全国着迷"。
