Why is it called whiteness, and why is it divided into large whiteness

Excerpt from a poem by Xin Qiji!

The full word is as follows:

Qingyu Case: Yuan Xi".

The east wind blooms thousands of trees at night, and blows down, and the stars are like rain. BMW carved cars are full of fragrance. The sound of the phoenix flute moves, the light of the jade pot turns, and the fish and dragon dance all night. The moth snow willow **wisps, the laughter is full of dark fragrance. The crowd looked for him, and suddenly looked back, but the man was in the dim lamp.

There is also the meaning of "ferry", what are you looking for? Use "ferrying" for a while!

Inc) was founded at the end of 1999 in Silicon Valley, USA, by Robin Li, a senior information retrieval technology expert and the sole holder of a patent for hyperchain analysis, and his friend Dr. Yong Xu, executive vice president who has many years of successful business experience in Silicon Valley.

It is currently the world's best Chinese information retrieval and transmission technology provider. More than 80% of all search engine portals in China** are powered by search engine technology, and existing customers include Sina, Tencent CN, Shanghai**, Guangzhou Windows, Xinhuanet, Northern Space, Western Space, Chongqing**, Jilin Information Port, Daqing Information Port, Dongfang**, Hunan Information Port, Nanyang Information Port, and Shunde Information Network.

The search engine uses a high-performance "web spider" program to automatically search for information on the Internet, and the customizable, highly scalable scheduling algorithm enables the search machine to collect the maximum amount of Internet information in a very short time. There are servers in all parts of China and the United States, and the search scope covers Chinese-speaking regions such as Chinese mainland, Hong Kong, Taiwan, Macau, Singapore, and some sites in North America and Europe. The search engine has the world's largest Chinese information database, with a total of more than 600 million pages, and is still growing rapidly at a rate of hundreds of thousands of pages per day.

The two characters originate from the poem "Qingyu Case" by the Chinese Song Dynasty lyricist Xin Qiji: "The crowd seeks a thousand of them", symbolizing the persistent pursuit of Chinese information retrieval technology.

Now they make money by rankings, so the phrase has been changed internally"The crowd is looking for him to sign"Finish. The employees there seem to be living to sign bills"I don't know if they're in pain and happy"。Huh

The unit of whiteness is "%", such as the whiteness of newsprint is 55% to 70% (i.e. 55 70 degrees).

In general, when the reflectance of the surface of an object to all wavelengths in the visible spectrum is above 80%, the surface of an object can be considered white. The whites are located in a fairly narrow range of color space, and they, like other colors, can be represented by three-dimensional quantities (i.e., light reflectance y, purity c, dominant wavelength).

However, people are accustomed to quantitatively evaluate the whiteness of different whiteness objects according to the order of one-dimensional whiteness (w), and take the ideal whiteness (such as high-purity barium sulfate, whose whiteness value is 100%) as the reference standard. Whether it is a visual assessment of whiteness or an instrument, it must be based on a recognized "standard".

Summary. Hello, it's not big, do you want to consult why it's called?

Hello, it's not big, do you want to consult why it's called?

Wait a minute, I'll see.

Which big point has the same content, and why is the content different after the two clicks are opened?

Is it bigger handwriting?

There is a large-print version, which is a larger number of words.

Hey, maybe I misunderstood, thank you.

You're welcome.
