根据定义，非贵金属合金是指合金中贵金属总含量(重量)小于_______％。

In addition to satisfying the target market's needs, the product is important because it is how organizations generate revenue. It is the "thing" that for-profit companies sell in order to realize profits and satisfy stakeholders and what a non-profit organization use to generate funds needed to sustain itself. Without a well-developed product strategy that includes input from the target market, a marketing organization will not have long-term success.

What I like about the Fortune 500 list
The Fortune 500 isn't made for light reading. (8) ____ The 500 is based on U. S.-based compaflje5, publicly reported revenue, not on any quality-based metrics, You get high-grade companies such as Warren Buffett's Berkshire Hathaway (No. 7) nestled near utter dogs such as Fannie Mae (No. 5). (9) My favorites:
LeBron who？ Last summer, Cleveland sustained a psychic trauma when basketball star LeBron James dumped the Cavaliers and went to Miami. Now the home of the Rock and Roll Hall of Fame has gotten a little mojo back by adding a company to the Fortune 500: Cliffs Natural Resources. (10)It could have been better for Cleveland, though. The company used to be known as Cleveland-Cliffs Inc. but renamed itself in 2008, saying, "We're no longer only a North American iron ore player.”LeBron-Cliffs, anyone？
Chrysler returns. The automaker fell off the list 13 years ago, when it was acquired by Daimler-Benz (later DaimlerChrysler) in what proved to be one of the worst corporate deals ever, right up there with Time Warner (owner of Fortune's publisher) selling itself to AOL in 2001. Daimler dumped Chrysler onto the Cerberus leveraged-buyout firm, which put up almost nothing but still overpaid. (11) It has no publicly traded stock. Under the terms of its federal bailout, however, it has to file financial reports with the SEC, so it's list-eligible again. Welcome back, No. 59.
Exit Unisys. Enter Cognizant. These two information technology firms are heading in opposite directions. (12) _ But the company's revenue dropped in 2010, and this year it's fallen off the list, to No. 520. Meanwhile, Cognizant, on Fortune' s list of fastest-growing companies for a record eight straight years, has grown its way into the 500(No. 484) only three years after first making the Fortune 1,000. (13) Unisys, by contrast, was formed in 1986 by combining old-line computer companies Burroughs and Sperry.
Finally, Buffett. His Berkshire Hathaway cracked the top 10 in revenue and profit for the first time because last year it bought the 78 percent of Burlington Northern that it didn't already own. (Buffett, a longtime director of The Washington Post Co.,steps down this month.)As part of that deal, Buffett split Berkshire Hathaway' s B shares 50 for 1.
(14) ___ So I decided it was time to sell half my Berkshire stake, held in an IRA, into the run-up. The stock's since risen 10 percent. Oh, well. Yet another example of why he's Warren Buffett and I write for a living.
Now match the statements (8-14) to the letter (A, B, C or D).
A Unisys was one of only 62 companies to have been in the 500 every year since Fortune started the list in 1955.
B Cliffs, which is heavy into iron ore pellets, coal and other industrial raw materials, doubled its revenue with the aid of acquisitions and leapt to No. 477 on this year's list from No. 750 last year.
C Cognizant, formed in 1994, is a creature of the offshoring world, with most of its development centers in India.
D I found some of this year's corporate comings and goings especially interesting.
E That got it listed on the S&P 500 index, forcing index investors to buy it and running up its price.
F Chrysler went broke and is now run by Fiat; it is owned primarily by Fiat and a trust for Chrysler workers and retirees.
G But if you leaf through the list at random, the way I used to leaf through the Book of Knowledge encyclopedia when I was a kid, you come across all sorts of stuff that's kind of fun.
