Components and equipment include— (a) solar collectors containing absorbers, that may be assembled in an array connected to the same storage container;(b) heated water storage containers that may have additional means of heating to supplement the solar input together with a controller for that heating;(c) pumps and controllers for circulation of the water or other heat transfer fluid between the collector/heat pump and the container.(d) heat pumps for energy collection or energy transfer; and (e)heat exchangers1.3.4 Packaged or factory made systemsSolar water heating systems may be supplied as packaged systems comprised of a complete set of matched components supplied from one source, or may be customized by assembling components from various sources on site.Packaged or factory-made solar water heating systems are batch products with one trade name, sold as complete and ready to install kits, with fixed configurations. Systems of this category are considered as a single product and assessed as a whole. If a packaged system is modified by changing its configuration or by changing one or more components, the modified system is considered a new system for which a new conformance report will be necessary.Customized or custom-built solar water heating systems are either uniquely built or assembled by choosing from an assortment of components. The components are separately tested and the test results are integrated to give an assessment of the whole system.*O n 05/08/2009 06:45 P M M a c k e n z i e P l u m b i n g & D r a i n a g e L t d p u r c h a s e d a s i n g l e u s e l i c e n c e t o s t o r e t h i s d o c u m e n t o n a s i n g l e c o m p u t e r .

极端天气英语演讲
极端天气英语演讲From 2016 to 2019, meteorologists saw record-breaking heat waves around the globe, rampant wildfires in California and Australia, and the longest run of category 5 tropical cyclones on record. The number of extreme weather events has been increasing for the last 40 years, and current predictions suggest that trend will continue.在2016到2019年间，气象学家在全球观测到了前所未有的热浪，加利福尼亚州与澳大利亚山火肆虐，五级热带飓风的持续时间也创下了纪录。
过去40年来，极端天气事件发生的次数在持续增加，而当前的预测表明，这一趋势还会继续下去。
But are these natural disasters simply bad weather? Or are they due to our changing climate? To answer this question we need to understand the differences between weather and climate— what they are, how we predict them, and what those predictions can tell us.但这些自然灾害仅仅是“天气不好”吗？还是源自我们的气候变化？要回答这个问题，我们首先要理解天气与气候之间的区别——它们是什么？如何进行预测？预测结果又代表了什么？Meteorologists define weather as the conditions of the atmosphere at a particular time and place. Currently, researchers can predict a region’s weather for the next week with roughly 80% accuracy. Climate describes a region’s average atmospheric conditions over periods of a month or more. Climate predictions can forecast average temperatures for decades to come, but they can’t tell us what specific weather events to expect.气象学家将“天气”定义为在某个特定时间及地点的大气状况。

Dieser Typ wird in Teil 3 berücksichtigt, er enthält Formstücke, die für Anwendungen nach Artikel 3, Absatz 3, der Druckgeräterichtlinie (97/23/EU) eingesetzt werden können.Im zweitens Teil legen die Normen über Bauteile der Kategorien I — IV unter der Druckgeräterichtlinie fest,dass das Formstück eine definierte Festigkeit gegen Innendruck hat. Dieser Ansatz bedingt erhöhte Anforderungen, die im Teil 4 berücksichtigt sind.Anhang A (informativ) enthält Informationen über besondere Maße der Formstücke und Anhang B (informativ)enthält Vorzugsmaße für Innendurchmesser und Wanddicken.Die Auswahl des Stahlwerkstoffes und das Anforderungsniveau hängt von vielen Faktoren ab; die Eigenschaften des Mediums, die Betriebsbedingungen, der Berechnungscode und gesetzliche Anforderungen sollten berücksichtigt werden. Daher gibt diese Norm keine detaillierten Richtlinien für die Anwendung der unterschiedlichen Bauteile. Es liegt letztlich in der Verantwortung des Anwenders, den entsprechenden Teil für die vorgesehene Anwendung auszuwählen.² (QWZXUI ²prEN 10253-3:2004 (D)51 Anwendungsbereich 1.1Dieser Teil der EN 10253 legt die technischen Lieferbedingungen für nahtlose Formstücke zum Einschweißen (Rohrbogen, konzentrische und exzentrische Reduzierstücke, T-Stücke mit gleichem oder mit reduziertem Abzweig, Kappen) aus nichtrostendem austenitischem und austenitisch-ferritischem (Duplex-)Stahl, ohne spezielle Anforderungen an die Prüfung fest.Diese Norm spezifiziert:¾ die Stahlsorten;¾ die mechanischen Eigenschaften;¾ die Maße und Grenzabmaße;¾ die Anforderungen an die Prüfungen;¾ die Prüfbescheinigungen;¾ die Kennzeichnung;¾ die Versandvorbereitung und Verpackung.1.2Falls in diesem Teil der EN 10253 nichts anderes festgelegt ist, gelten die allgemeinen technischen Lieferbedingungen nach EN 10021.1.3AnwendungsgrenzenDie zulässigen Drücke und Temperaturen unterliegen der Verantwortlichkeit des Bestellers gemäß dem Stand der Technik und unter Anwendung der in den geltenden Vorschriften, technischen Regeln oder Normen festgelegten Sicherheitsbeiwerte.Schweißnahtfaktoren werden allgemein bei der Berechnung der Wanddicken von Bauteilen verwendet, die eine oder mehrere Stumpfnähte aufweisen, die nicht in Umfangsrichtung liegen:¾ bei Bauteilen, von denen Stichproben einer zerstörungsfreien Prüfung unterzogen werden: 0,85¾ bei Bauteilen, die lediglich einer Sichtprüfung unterzogen werden: 0,7.2 Normative VerweisungenDie folgenden zitierten Dokumente sind für die Anwendung dieses Dokuments erforderlich.

英语高级视听 听力原文 Unit 5 The global warning
Unit 5 The global warningThe North Pole has been frozen for 100,000 years. But according to scientists, that won't be true by the end of this century. The top of the world is melting.There's been a debate burning for years about the causes of global warming. But the scientists you're about to meet say the debate is over. New evidence shows man is contributing to the warming of the planet, pumping out greenhouse gases that trap solar heat.Much of this new evidence was compiled by American scientist Bob Corell, who led a study called the "Arctic Climate Impact Assessment." It's an awkward name — but consider the findings: the seas are rising, hurricanes will be more powerful, like Katrina, and polar bears may be headed toward extinction.What does the melting arctic look like? Correspondent Scott Pelley went north to see what Bob Corell calls a "global warning."Towers of ice the height of 10-story buildings rise on the coast of Greenland. It's the biggest ice sheet in the Northern Hemisphere, measuring some 700,000 square miles. But temperatures in the arctic are rising twice as fast as the rest of the world, so a lot of Greenland's ice is running to the sea."Right now the entire planet is out of balance," says Bob Corell, who is among the world's top authorities on climate change. He led 300 scientists from eight nations in the "Arctic Climate Impact Assessment."Corell believes he has seen the future. "This is a bellwether, a barometer. Some people call it the canary in the mine. The warning that things are coming," he says. "In 10 years here in the arctic, we see what the rest of the planet will see in 25 or 35 years from now."Over the last few decades, the North Pole has been dramatically reduced in size and Corell says the glaciers there have been receding for the last 50 years.Back in 1987, President Reagan asked Corell to look into climate change. He's been at it ever since.In Iceland, he showed 60 Minutes glaciers that were growing until the 1990sand are now melting. In fact, 98 percent of the world's mountain glaciers are melting.Corell says all that water will push sea levels three feet higher all around the world in 100 years."You and I sit here, another foot. Your children, another foot. Your grandchildren, another foot. And it won't take long for sea level to inundate," says Corell."Sea level will be inundating the low lands of virtually every country of the world, ours included," Corell predicts.To find the sights and sounds of the arctic melting, there are few places better than a fjord in Greenland, with a glacier just a short distance away.Pelley stood on a huge block of ice that had split off from the glacier and had dropped into the sea — a big iceberg."This part of Greenland is melting faster than just about any other. To get a sense of the enormity of what's happening, consider this: The ice that is melting here is the equivalent of all the ice in the Alps," Pelley explained, standing atop the iceberg.That's more than 105 million acres of melted ice in 15 years. Just four minutes after Pelley cleared off this berg, part of the ice caved in.60 Minutes got a bird's-eye view of how unstable the ice is becoming on a flight with glaciologist Carl Boggild.Boggild anchored 10 research stations to the ice. But every time he comes to visit, the ice and his stations have moved.Flying over the ice, Pelley noticed lots of fissures and crevices breaking through the ice.Asked what causes this, Boggild explained, "This is actually the ice flow, where you have so much tension in the ice that it cannot stick together. And it breaks and opens a crevice which goes about 150, 200 feet down."The ice is also melting on the sides, Boggild says.High overhead, Pelley remarked that one could hear the water running."It's like a small river," Boggild said.A leading theory says those little rivers lubricate the bottom of the ice sheet, helping it move off the bedrock and out to sea.And there may be no stopping it. Arctic warming is accelerating. It's a chain reaction. As snow and ice melt they reveal dark land and water that absorb solar heat. That melts more snow and ice, and around it goes.There's long been a debate about how much of this is earth's naturally changing climate and how much is man's doing. Paul Mayewski, at the University of Maine, says the answer to that question is frozen inside an ice core from Greenland.With funding from the National Science Foundation, Mayewski has led 35 expeditions collecting deep ice cores from glaciers. The ice captures everything in the air, laying down a record covering half a million years."We can go to any section of the ice core, to tell, basically, what the greenhouse gas levels were; we can tell whether or not it was stormy, what the temperatures were like," Mayewski explains.60 Minutes brought Mayewski back to Greenland, where he says his research has proven that the ice and the atmosphere have man's fingerprints all over them.Mayewski says we haven't seen a temperature rise to this level going back at least 2,000 years, and arguably several thousand years.As for carbon dioxide (CO2) levels, Mayewski says, "we haven't seen CO2 levels like this in hundreds of thousands of years, if not millions of years." What does that tell him?"It all points to something that has changed and something that has impacted the system which wasn't doing it more than 100 years ago. And we know exactly what it is. It's human activity," he says.It's activity like burning fossil fuels, releasing carbon dioxide and other greenhouse gases. The U.S. is by far the largest polluter. Corell says there's so much greenhouse gas in the air already that more temperature rise is inevitable.Even if we stopped using every car, truck, and power plant — stopping all greenhouse gas emissions — Mayewski says the planet would continue towarm anyway. "Would continue to warm for another, about another degree," he says.That's enough to melt the Arctic — and if greenhouse gases continue to increase, the temperature will rise even more. The ice that's melting already is changing the weather by disrupting ocean currents.Corell points to floods in the U.S., heat waves in Europe; and 60 Minutes wanted to know about the catastrophic 2005 hurricane season."The one thing I think we can say with a fairly high degree of confidence is the severity of the storms, how strong the storms, these cyclonic events like hurricanes and cyclones in the Pacific, are going to get — they're gonna be more severe. Now one thing that is in doubt is whether there'll be more of them," Corell explains."The oceans of the Northern Hemisphere are the warmest they've been on record. When they get up in that temperature, they spin off hurricanes. Well, if it goes up another degree, it's gonna spawn these with more intensity," Corell says.The name "arctic" comes from ancient Greek meaning "Land of the Great Bear."But the warming climate is threatening this icon of the arctic, the polar bear. Flying above the sub-arctic region of Hudson Bay, Canadian scientist Nick Lunn is hunting polar bears in a 30-year study that tracks their health. It's the job of his assistant Evan Richardson to take them down with a tranquilizer dart.Once tranquilized, Lunn carefully checks the bear with a pole, without getting too close.The polar bear is the largest predator on land. Native people in the region say he'll even hunt humans, but not on the day Pelley joined Lunn: with the tranquilizer, the bear was awake but immobile.The scientists knew this bear by his tattoo. His history is written chapter and verse in the "bear bible.""This is the record book of all the bears that have been handled by us or Manitoba Conservation," Lunn explains.The study began at the Wapusk National Park, because the bear population was thought to be the healthiest in the world.Lunn's annual checkup records changes in fat, dimensions and an inventory of weapons. The polar bear uses its teeth to hunt primarily one thing — seals. That's where arctic warming comes in.Polar bears can only hunt on the ice. Lunn says the ice is breaking up three weeks earlier than it did 30 years go. He's now finding female bears 55 pounds lighter — weaker mothers with fewer cubs.Asked how the bear population has changed since he started his research, Lunn says, "When we first started doing this research, we've done inventories in the mid-80s, in the mid-90s. Both times we came out with an estimate of approximately 1,200 animals for what is known as the western Hudson Bay population. The numbers now suggest that the population has declined to below 1,000."The bears are unlikely to survive as a species if there's a complete loss of ice in summer, which the arctic study projects will happen by the end of this century.There are skeptics who question climate change projections like that, saying they're no more reliable than your local weatherman. But Mayewski says arctic projections done decades ago are proving accurate."That said, the skeptics have brought up some very, very interesting issues over the last few years. And they've forced us to think more and more about the data that we collect. We can owe the skeptics a vote of thanks for making our science as precise as it is today," says Mayewski.One big supporter of climate science research is the Bush administration, spending $5 billion a year. But Mr. Bush refuses to sign a treaty forcing cuts in greenhouse gases.The White House also declined 60 Minutes' request for an interview. Corell, who first studied the issue for President Reagan, believes the climate change facts are in, even if President Bush does not."When you look at the American government, which is saying essentially, 'Wait a minute. We need to study this some more. We can't flip our energy use overnight. It would hurt the economy.' When you hear that, what do you think?" Pelley asked."Well, what I do then is, I try to tell them exactly what we know scientifically. The science is, I believe, unassailable," says Corell. "I'm not arguing their policy, that's their business, how they deal with policy. But my job is to say,scientifically, shorten that time scale so that if you don't push out the effects of climate change into the long, long distant future. Because even under the best of circumstances, this natural system of a climate will continue to warm the planet for literally hundreds of years, no matter what we do."。

夏冰雹频道 英语讲解
夏冰雹频道英语讲解The Phenomenon of Summer Hailstorms.Hailstorms, a weather phenomenon that is often associated with colder climates, can be a surprising occurrence during the summer months. While they are less frequent than in other seasons, summer hailstorms can be particularly intense and damaging, posing a challenge to both meteorologists and those caught in their path.The formation of hailstones begins with the development of a thunderstorm. Within these storms, strong updrafts –powerful currents of air rising rapidly – lift condensation nuclei, such as dust and pollen, into the colder regions of the atmosphere. As these nuclei ascend, they attract moisture, forming small ice crystals. These crystals continue to grow as they are carried higher into the storm, where the temperature is significantly lower.As the ice crystals encounter even colder air, theyfreeze into small ice pellets. These pellets are then carried further upward by the updrafts, sometimes reaching altitudes of several kilometers. During their ascent, the pellets grow larger as they collect more ice and collide with other pellets, eventually forming hailstones.The size of the hailstones depends on several factors, including the strength of the updrafts and the duration of time the pellets spend in the colder regions of the atmosphere. Stronger updrafts can support the growth of larger hailstones, while longer durations allow more time for the pellets to accumulate ice.Once the hailstones reach a certain size, they become too heavy to be supported by the updrafts and begin to fall back to the ground. This process can be quite rapid, with hailstones reaching speeds of up to 90 kilometers per hour. As they descend, the hailstones can grow even larger as they collect more ice from the surrounding air.The impact of these falling hailstones can be devastating. Depending on their size and density,hailstones can cause significant damage to crops, vehicles, and even buildings. The weight and force of the hail can dent car bodies, break windows, and shatter roof tiles. Agricultural crops can be destroyed, leading to significant economic losses.In addition to the physical damage, summer hailstorms can also pose a threat to human life. Flying hailstones can cause injuries, particularly to those outdoors during the storm. Flooding can also be a concern, as the intense rain accompanying the hailstorm can quickly lead to the accumulation of water.Predicting summer hailstorms is challenging due totheir sporadic and unpredictable nature. Meteorologistsrely on a combination of radar, satellite imagery, and weather models to monitor the development of thunderstorms and assess the potential for hail. However, accurate forecasting of hailstorms remains a challenge, as the conditions that lead to their formation can vary widely.Despite the difficulties in predicting and mitigatingthe impact of summer hailstorms, there are some steps that can be taken to reduce their effects. Building structures can be designed to withstand hail impact, using stronger materials and impact-resistant glazing. Farmers can plant crops that are less sensitive to hail damage, or employ techniques such as hail netting to protect their plants. Additionally, early warning systems can provide advance notice of impending storms, allowing individuals and communities to take precautionary measures.In conclusion, summer hailstorms are a unique and potentially destructive weather phenomenon. Their formation, characteristics, and impact on society highlight the complexity and unpredictability of nature. Asmeteorological understanding and technology continue to advance, so does our ability to monitor, predict, and mitigate the effects of these remarkable natural events.。

Now, within a matter of hours, that dream was slipping away. But Diana insisted,“ I don't care what the doctor says!

听力原文节目简介
Now, the weather this week…
There’s a lot of cloud across the UK, swirling around…
Let’s have a look at the weather then, it’ll be staying dry…
But what about the sunshine, that’s been the problem over the last few days…
Helen: Hello, I’m Helen.
Yang Li: And I’m Yang Li.
Helen: You might have guessed, we’re talking about the weather today.
Yang Li: 天气对英国人来说可是永远不会厌倦的话题。
Helen: And the British are famous for their views on weather, they complain about it all the time. So is the weather really as bad as it sounds in the UK?
Yang Li: 是啊，英国的天气是不是真的那么让人受不了呢？让我们来听听老百姓是怎么想的吧。
Insert
I think when it’s too hot, we say it’s too hot. When it’s too cold we say it’s too cold. When it rains, it’s raining. But I think our weather is pretty good actually.
Yang Li: 这位先生说尽管气候经常变化，但是他觉得总的来说英国天气还是不错的 it’s pretty good actually.
Helen: What about the others?
Insert
Typical British summer, isn’t it? Not as good as it could be unfortunately.
Yang Li: 这位女士对英国的夏天可没有信心。
Helen: She says it’s a typical British summer and unfortunately not as good as it could be. Insert
Weather doesn’t determine what I do in my life, but I think a lot of English people do. They like it warm, don’t they? No, I like it like this.
Yang Li: 一听口音，就知道这位女士是从苏格兰来的。
她说天气好坏对她来说无所谓， weather doesn’t determine what she does in life.
Helen: But she thinks a lot of English people do care about the weather and they like warm and sunny days.
Insert
If it’s too hot, we moan, I think. If it’s too cold, we moan, so it’s a happy medium and just nice today.
Yang Li: 我觉得这位老先生的话倒是很贴切。
他说天气太热，我们会抱怨 to moan, 天气太冷我们也抱怨。
Helen: Well, the Brits do moan a lot about everything. We love complaining.
Yang Li: 天气真的会让英国人唠叨不休吗？前任英国国会议员 Ann Widdecombe 认为, 这正是英国人固有的一个特征。
Insert
I think we’re just naturally a nation of grumblers.
Yang Li: Ann 认为英国人天生就喜欢抱怨。
Helen: We are a nation of grumblers.
Yang Li: To grumble 埋怨。
A grumbler 就是一个喜欢埋怨的人。
Helen: She gave people’s attitude towards politicians as an example.
Yang Li: Ann 还用英国人对政治家们的看法打了个比方。
Insert
For example, when the politicians are here and doing their duty, we’re moaning all the time about how they interfere and how we’d wish they’d go away. When they go on holiday, we moan that they’ve had the audacity to take a holiday.
Yang Li: 她说当政治家们在议会办公的时候，人们埋怨他们老是做出干扰人民生活的决定 interfere with our lives. 巴不得他们别上班才好呢。
Helen: Yes, we moan about how the politicians interfere with our lives and we wish they’d all go away.
Yang Li: 可是当政治家们度假去了的时候，人们却又埋怨他们怎么可以不管国家大事，竟敢放假。
Helen: Have the audacity to take holidays.
Yang Li: Audacity 就是大胆妄为的意思。
Ann 举这个例子就是说英国人的思想往往是矛盾的。
Insert
So there’s no pleasing us. And the weather, because it happens every day of course, that the weather changes, the weather is a great opportunity to unleash our moaning tendencies.
Helen: And as Ann puts it, because the weather changes every day, it’s a great opportunity to unleash our moaning tendencies.
Yang Li: 多变的天气也就成了英国人发牢骚的好机会 a great opportunity to unleash their moaning tendencies.
Helen: I have to say the weather in the UK can be unpredictable. Often we experience the four seasons in just one day. Every time you look up, there’s a new page to read.
Yang Li: That’s true. 英国的天气的确令人难以预料，变化无常。
Helen: So Li, you’ve lived in the UK for a long time. What do you think of the weather?
Yang Li: Well, I think it’s perfect. Not too cold and not too hot.
Helen: No complaints then.
Yang Li: Erm, maybe occasionally.
