Oxford PV, a British company, is bringing some of the first perovskite solar cells to market.

英国牛津公司将首批钙钛矿型电池推向市场。

The progress of the other main kind of solar technology, photovoltaic (PV) solar cells, looks stronger.

另一项主流科技，发电板进展顺利，前景广阔。

In photovoltaic cells or PV cells, when sunlight hits semiconductor material, such as silicon, it creates a pair of electron holes.

在电池或 PV 电池中，当照射到半导体材料，如硅，就会产生一对电子空穴。

Researchers have been working on a new vaccine for rotavirus called BRV-PV.

研究人员一在研究一种名为 BRV-PV 轮状病毒新疫苗。

The researchers say the clinical trial shows that BRV-PV was nearly 67 percent effective.

研究人员表示，临床试验表明 BRV-PV 有效性接近 67%。

So we have a lot to listen to. PV: And a lot to learn.

WG：所以我们有很多东西要听。 PV：还有很多东西要学。

Each section of the canopy is covered with customised PV panels that will generate around four megawatts of power.

顶篷每个部分都覆盖着定制面板，可产生约 4 兆瓦电力。

Also, one would expect the % total variation to be the sum of the %EV, %AV and %PV.

此外，人们预计总变异百分比是 %EV、%AV 和 %PV 之和。

We need to raise the bar. PV: Elevate our standards for racial literacy.

WG：我们需要提高标准。 PV：提高我们种族素养标准。

There are approximately 323 million people in the United States. PV: And 7.4 billion people on the planet.

美国大约有 3.23 亿人。 PV：地球上有 74 亿人。

Solar power is one of the most reliable forms of renewable energy, working by converting sunlight into electricity through photovoltaic technology, or PV.

是最可靠可再生源之一，它通过技术将转化为电。

We don't know how to communicate -- PV: Live together -- WG: Love one another.

WG：我们不知道如何沟通 -- PV：一起生活 -- WG：彼此相爱。

For instance, the International Space Station, the most expensive structure ever built by humans, is powered by an assortment of solar panels made of PV cells.

例如，国际空间站是人类有史以来建造最昂贵建筑，它是由各种由电池制成电池板供电。

Alice, how big of a deal would it be if Oxford PV went overseas to build this factory and to raise more money?

Alice，如果 Oxford PV 去海外建这个工厂并筹集更多资金，那会有多大交易？

The Oxford PV said the UK was the least attractive country simply because it lacked the incentives for solar companies to build their factories there.

牛津表示， 英国是最没有吸引力国家， 因为它缺乏公司在那里建厂动力。

The part variation (PV) is found by determining the range in part values (Rp) and multiplying this range by a constant (K3) that depends on the number of parts.

通过确定零件值 (Rp) 范围并将该范围乘以取决于零件数量常数 (K3)， 可以找到零件变化 (PV)。

Now a high-profile solar power developer called Oxford PV says it's more likely to set up a new factory overseas and list on either the New York or Hong Kong stock market.

现在，一家名为 Oxford PV 知名开发商表示， 它更有可在海外设立新工厂， 并在纽约或香港股票市场上市。

I think, for example, the mining sector has a great opportunity to be the solution for the environmental issues, because we provide the copper, the cobalt, the lithium that are required for solar PV panels, for battery storage.

我认为， 例如，采矿业有很大机会成为环境问题解决方案，因为我们提供板和电池存储所需铜、 钴和锂。
