閱讀英語文摘要多少詞彙

① 英語文摘詞彙量多少

7000。英語文摘是由世界襲歲瞎拍空知識出版社發行的中英雙語刊物，每月發行一次。英語文摘雀滾詞彙量7000，是一份優質文檔。

② 我想買一個翻譯筆閱讀英語文摘,來擴大詞彙量,這翻譯筆好用么

我當年學英語就是找一本很難得書，自己基本上隔兩個詞就要查的喚圓那種，字典查完了自己把詞和音標寫下來，這樣其實有助於你記住和培塌它。不要怕慢，其實過程長才會加深你的印象。我發現我網上查的很多詞一會兒就都中汪忘了

Tapping the Low Hydrogen Porosity Problem

Tapping the Low Hydrogen Porosity Problem
By Dan Mahony, Technical Salesman, and Paul Gramp, Distributor Trainer, The Lincoln Electric Company.

Stick Welding Porosity in a weld is considered poor quality. Porosity may, or may not, be visible to the naked eye. Occasionally porosity can be found in the face of the weld while sometimes the face may appear porosity free, but deep inside the weld, porosity may exist. Porosity looks "sponge like" or like tiny bubbles in the weld. Porosity in a weld can be located using several different methods of non-destructive testing, such as radiographic (x-ray), UT (ultrasonic) and die penetrate.

"...strike the arc, then lift the electrode up for a moment or two, allowing a few drops of electrode to fall from the tip."

Although some porosity found at the beginning of a weld made with low hydrogen electrodes is not always apparent, it is possible and the solution itself may be simple. Often, even with an experienced welder, weld testing will show slight porosity at the beginning of a weld for no apparent reason. Porosity is often found when using low-hydrogen electrodes such as E-7018, and it may be difficult to establish why this occurs.

Stick Welding In order to understand the real cause, it is necessary to look at the way stick electrodes are manufactured, as well as how they are used in the field. The steel core wire, as we know, concts electrical current from the electrode holder to the work . It also melts to become the filler metal. The chemical coating that forms the flux layer is extruded on to the steel core wire and baked in a controlled oven to remove moisture. The flux coatings major task is to vaporize and form a shielding gas to protect the weld puddle from nitrogen, hydrogen and oxygen.

During manufacturing, after the coating is applied and it is still soft and pliable, a set of brushes removes coating to accommodate the electrode holder. Another set of brushes slightly tapers the work end of the electrode to expose the end of the steel core wire. This exposed end allows a short circuit to be established when it touches the work at the start of the weld. As the weld progresses, the steel wire burns slightly up inside the flux (approximately 1/8 of an inch), so the coating melts to form the necessary shielding gas. Striking a new electrode, however, the tapered coating at the end of the electrode provides only minimal shielding since some of the coating was intentionally removed to accommodate easier arc starting. Therefore, if the operator lowers the electrode into the puddle immediately, some porosity may result at the beginning of the weld, which is caused by insufficient amount of coating on the steel core wire.

This condition also exists when re-striking an electrode that has already been used. Before striking an arc, the welder frequently taps the end of the electrode on the ground to break away flux at the tip. Breaking away the flux to expose the steel core wire, while helping to achieve the short circuit necessary to start the arc, creates conditions for improper arc shielding, sometimes resulting in porosity at the start of the weld. This practice is much more common with low hydrogen electrodes, since the core wire melts up inside the flux coating. Electrodes such as E-6010 and E-6011 use organic coatings (paper), which the coating tends to burn back enough to leave the end of the core wire exposed.

Stick WeldingThis type of porosity can be avoided if the operator is trained to strike the arc correctly. Immediately after establishing the arc, lift the electrode up a short distance from the work and holding it there for a second or two, allow a few drops of molten steel to fall from the tip of the electrode. The arc will bring the tip of the electrode up to operating temperature quickly, enabling the core wire to burn up inside the flux coating and initiate the gassing effect of the flux. Then, when the electrode is lowered to the work, the weld will be properly shielded, and porosity will be minimized.

Proper training is always important to achieving good results in welding. Training is even more critical when dealing with low hydrogen electrodes. A little understanding of how these electrodes differ and the consequences of improper electrode handling will pay big dividends in better weld quality and fewer porosity defects.

⑦ 考研英語閱讀如何備考更高效

做閱讀時，第一遍翻譯：不要查單詞，翻語法書，就根據自己認識的詞，自己的理解翻譯；第二遍翻譯：這一遍可以查單詞了，把第一遍翻譯時不認識的詞和短語都查查，看看自己第一遍猜對了沒有。第三遍翻譯：這一次可以拿著參考答案的譯文攜鍵來對照了，包括嫌敬【{[【【http://yz.kuakao.com/beikao/n-495088.html 】答案中一些對長難句的解析都要看，看看自己欠缺在哪裡，第四遍翻譯：有了前三遍的基礎，，對大多數單詞和句子以及翻譯也都了解了，那麼，忘記參考譯文，重新再翻譯一遍。相信這么多的辯者巧話，你閱讀肯定能提高不少的。

⑧ 英語學習和英語文摘那個難

英語文摘難些

涉及很多專業詞彙 看起來很費勁

我覺得英語文摘適合專業四級的了

雜志只是一個輔助 像我們看青年文摘一樣

你先去買一本看看嘛~~~

瘋狂英語就比較適中
