查询词典 doublings

Manholes for engine room double bottom tanks to be mounted on angle bar coaming, 200 mm high, all other manholes to be fixed on doublings or to be flush with deck in way of passageways.

机舱双层底舱的人孔应安装有角钢制的围板，高度为200mm，所有其它的人孔应安装在双层底或通道处并与甲板平齐。

The second algorithm compute 2k P directly from P, where P is a random point on an elliptic curve, without computing the intermediate points, which is faster than k repeated doublings.

该算法从P直接计算2~kP，不需要计算中介点，因此较k次倍乘快，其实现效率与投射坐标下的算法相当。

The method this paper discussed was based following theoretic analysis: Square and multiplication of large integer are two basic operations in modular exponential m_ary algorithm. The main operations of m_ary algorithm of point multiplication in elliptic curve encryption were doublings and point addition. The steps of m_ary algorithm in point multiplication was similar to modular exponential.

其基于以下理论分析：模幂m_ary算法的基本运算为大数乘法，其中包括大数平方算法和一般大数乘法；椭圆曲线加密算法中点乘的m_ary算法步骤与模幂的m_ary算法相同，后者的基本运算为倍乘和加法。

Carl Sagan has entertainingly described this phenomenon, musing about the destiny of bacteria that reproduce by dividing into two every 15 minutes. Says Sagan:"That means four doublings an hour, and 96 doublings a day. Although a bacterium weighs only about a trillionth of a gram, its descendants, after a day of wild asexual abandon, will collectively weigh as much as a mountain...in two days, more than thesun - and before very long, everything in the universe will be made of bacteria." Not to worry, says Sagan: Some obstacle always impedes this kind of exponential growth. The bugs run out of food, or they poison each other, or they are shy about reproducing in public.

Carl Sagan 曾经开玩笑地解释这种现象，假设有一种细菌每15分钟可以分裂一次，亦即代表每一小时复制四次，一天可复制96次，虽然单一个细菌其重量只有一兆分之一公克重，但是只要经过一天无止尽的无性生殖，其重量可能会比一座山还重，经过两天后，甚至会比太阳还重，要不了多久所有的宇宙都将由这种细菌所组成，不过 Sagan 又说，大家不必担心，上天一定会安排障碍来阻止其倍数成长，有可能他会耗尽食物，或是毒死自己，或是有可能羞于在大庭广众之下复制。

In this study, we demonstrated that murine BMMSCs, after numerous passages, obtained unlimited population doublings and proceeded to a malignant transformation state, resulting in fibrosarcoma formation in io.

在此研究中我们发现鼠的BMMSCs在多次传代后会具有无限扩增的能力并进入一种恶性转化的状态，导致体内纤维肉瘤的形成。

MAIN OUTCOME MEASURES: Cell morphology and population doublings were observed.

主要观察指标：观察各组细胞形态学变化和群体倍增数。

Erfaillie and her team isolated MAPCs from mice and expanded them for at least 80 doublings in the lab.

erfaillie和她的同时在实验室里分离得到MAPCs并至少扩增80倍。

And we're only eight doublings away from it meeting 100 percent of our energy needs. And there is 10 thousand times more sunlight than we need.

我们只差8个倍增，就能达到百分之百的能源需求，而我们拥有比需要多一万倍的阳光。

Like Moore before him, he could see that the 18-month doublings in performance would continue to stretch out as far as anyone could see.

比如像他之前的摩尔，就看到了每18个月翻一番的增长速度，就像所有人都看到的那样将继续下去。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。
