双像

The negative angle of refraction behavior associated with the negative index of refraction exhibited by DNG metamaterials is demonstrated.

并利用点源模拟出平面双负材料具有突破Rayleigh衍射极限使倏逝波成像的能力即：完美透镜现象。

After inducing 1%～16% of the aniseikonia, there is no significant difference between double-screen ATBC and theoretical results. It illustrates that ATBC can reflect the ratio of the image size of the subjects'eyes successfully and it can be applied to clinical examinations as well as experimental studies.

人工诱导屈光参差后，双屏显示计算机不等像检查结果和理论计算值的差异无显著性，两者有很好的相关性，说明该检查能够准确的反映被检者双眼影像的大小，可以用于临床检查及实验研究。

Once the agent learns each aspect of the mdel that isn't given. For instance, it might know its utility, but not what the world looks like, which might be the case for an explorer robot, or it might know the state of the world, but not the value of its actions, as might be the case if the agent were learning to play a game like backgammon.

例如，它了解它的效用，但不知道世界看起来像什么，这可能是勘查机器人遇到的一种情况，或者它了解世界的状态，但不知道它的行为会获得多少分值（分值的概念见上文，译者注），如果智能体在学习玩游戏，比如西洋双陆棋时同样也可能发生这种情况。

Two detectors are used both in conventional differential astigmatic device and the device given in this paper.

与差动像散离焦检测原理相同的是，二者都是采用双探测器进行测量。

Here we are going to look at the single and double vertical bar charts, which look somewhat like this

在这里，我们将要看看单，双竖线图，这看起来有点像这样

Scorpios will be loyal and discreet -- another plus to Pisces -- and their feelings of love go awesomely deep.

He had short, bandy legs, long straggly ginger hair and bloodshot, baggy eyes that gave him the doleful look of a basset hound.

两条短短的罗圈腿，一头又长又乱的姜黄色头发，一双肿胀充血的眼睛，使得他看上去像一只短腿猎狗那样愁苦。

Double Bergen plays much like Bergen, except that there are four open ends rather than two.

双卑尔根发挥很像卑尔根，除有4个开放的结束，而非两个。

A spot of red appeared on Miss Su's cheeks beneath her lightly applied rouge , spreading out like oil stains on a piece of paper, covering her face in an instant and making her look bewitchingly bashful

苏小姐双颊涂的淡胭脂下面忽然晕出红来，像纸上沁的油渍，倾刻布到满脸，腼腆得迷人。

This technology can automatically detect the correctness of velocity field, which greatly improves the computation accuracy of focusing operator and the accuracy of bifocal amplitude-preserving imaging.

该技术可以自动检测宏观速度场正确与否，大大提高了聚焦算子的计算精度和双聚型保幅成像精度。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).
