The short range of the induction-loop antenna in the lens means the external antenna has to be very close to the eye: taped around the eye socket, in fact.

眼镜内感应圈天线短意味着外部天线离眼睛一定很近：实际上就是黏在眼眶周围。

One way around them is to adopt tools that support a closed-loop development cycle.

避免这些问题的一种方法是采用支持闭循环开发周期的工具。

Now I have the ability to create a loop, that is, to reuse the same pieces of code over and over again as I go around.

现在我们已经学会如何创建循环了，也就是，重复的一遍又一遍的,执行同一片代码。

Now this happens to be what we would call a linear process, because the number of times I go around the loop is directly related to the size of the argument. If I double 2 the argument, I'm going to double the number of times I go around the loop. If I increase it by five, 5 I'm going to increase by five the number of times I go around the loop.

这恰好是我们会成为,线性复杂度程序的一个例子,因为我要执行循环的次数是,和输入的参数的大小直接相关的,如果我将这个参数乘以,那么我就要将进行循环的次数也乘以2了，如果我把参数加上,那么循环的次数也要加上5了。

Ah ha, it goes into that accept portion, prints out a message, and goes back around the while loop to say try again. And it's going to keep doing this until I give it something that does serve as a float.

他会说输入一个浮点数，啊哈，它就到了那段处理代码,打印出消息,然后回到while循环让我们再输一次,它会持续这么做直到它接受到一个浮点数。

Presenting sweeping views of the city skyline, the greenway runs east to Beckton and, after the summer, will connect westward to a full loop around the city via Islington and the Regent's Canal.

It should be noted also that the agencies, their industrial partners and a number of "space tourism" advocates have all previously thought about repeating the Apollo 8 Moon mission, if only to do one simple loop around the back.

Industry experts say the wide loop Dragon is supposed to take around the space station, followed by various other maneuvers, could be a problem if the capsule burns more fuel than anticipated.
