A New Recipe For Counting Cranberries丨数蔓越莓的新方法

周末早上好！今天为大家带来的的听力内容和蔓越莓有关。

之前在做这篇内容的时候，霸姐说以前学校组织参观，蔓越莓长在水里，就像图片这样。

然后我就懵了，按道理蔓越莓应该是灌木吧，怎么会长在水里？

我俩一查才发现真相，因为蔓越莓贴地生长叶子盖果，大多采用水收法，果子浮起方便采摘。但这种收获法的果子基本只能做果干。少部分采用干收法得到的是鲜果，但是耗时费人力。

然后我俩就讨论，那鲜果岂不是很贵？

所有我们想问有人吃过蔓越莓鲜果么？咱们交个朋友呗～

蔓越莓收获后，在分拣的过程中需要计数，但是人工计数的工作量特别大。最近，科学家们研究出的新方法就解决了这个问题~

来，听录音学习了！

以下是英语简单霸进行翻译后的内容，旨在让大家学习英语的同时获取相关咨询。

Wisconsin is famous for cheese. But it's also the United States' number one producer of a tart, red fruit that’s on pretty much every Thanksgiving dinner table.

威斯康星州以奶酪闻名，但它也是蔓越莓派的美国第一大产地。蔓越莓派几乎遍布每张感恩节餐桌。

"We have this reputation of being the dairy state, but cranberries outnumber the cows." Susan Hagness, an electrical engineer at the University of Wisconsin—Madison.

“我们以乳制品出名，但是蔓越莓在数量上超过了乳制品。”威斯康星大学麦迪逊分校的电子工程师Susan Hagness说。

Cranberries, she says, are big business—they’re the official state fruit! And supply chain managers need estimates of the size of the upcoming harvest. Which can be hard to make.

她表示，作为威斯康星州的特产，蔓越莓是庞大的产业。供应链管理者需要对未来的收成进行估算，但这很难。

"The current approach for estimating cranberry yield is literally to go out into the field and hand pick and hand count all the cranberries in a one square foot area. This is obviously an inefficient and laborious approach. There can be up to 900 berries per square foot."

目前估算蔓越莓产量的办法就是对一平方英尺的蔓越莓逐一进行手工实地采摘和手工计数。这一方法显然低效、费力。每平方英尺可达900个莓果。

So scientists from Ocean Spray asked Hagness for help. And she and her team found in lab tests that zapping cranberry plants with microwaves, and then studying the signal that bounces back, mightwork. Recall that your microwave oven works by exciting water molecules in whatever you’re heating up. Same concept here: microwaves interact differently with plump, juicy cranberries—which contain lots of water—than they do with leaves. There turn signal thus provides a good estimate of the number of cranberry clusters in a given plot.

因此来自Ocean Spray（公司名称）的科学家向Hagness寻求帮助。她和团队在实验测试中发现，用微波对蔓越莓进行刺激，研究反射回来的信号，可能会有用。回想一下，微波炉通过刺激物体中的水分子而使其加热，同理，蔓越莓与其叶子相比含有大量水分，微波对二者的刺激可能产生不同的结果。因此，在给定区域内，反射信号可以很好地用于估算蔓越莓群的数量。

By the way, the microwaves for this application are very low power—on par with the radiation that comes out of a cell phone. "You know we're not cooking the cranberries right there in the field."

另外，这项应用的微波能耗很低——相当于一部手机的辐射量。“要知道，我们又不是在野外烹调蔓越莓."

The team presented their preliminary results at an IEEE conference earlier this year. [A Haufler et al, Feasibility of Efficient and Accurate Estimation of Cranberry Crop Yield using Microwave Sensing] Since then they’ve moved from the lab to the bog—they’re currently analyzing data from tests done during this year's crop. If the method holds up, it might give cranberry growers something to be thankful for.

今年早些时候，该团队在IEEE会议上展现了初期研究成果。[A Haufler et al, Feasibility of Efficient and Accurate Estimation of Cranberry Crop Yield using Microwave Sensing]之后，他们从实验室转移到了沼泽中，目前正在分析今年作物的实验数据。如果这一理论成立，蔓越莓种植者们可能会对此表示感激。
