  1. : The golden segmentation law, also known as the golden rate, is divided into two parts, which makes part of the ratio of all parts of the ratio of the other part. The most basic formula is to divide 1 to 0.618 and 0.382, and then change according to the actual situation, and then evolved into other computing formulas. The golden division law was discovered by Greek mathematician Pythagoras in the sixth century BC. Its basic content can be explained like this: If a line segment is divided into two parts, the ratio of the length of the long section and the short section is 1: 0.618. The perfect segmentation, this point of division is called the golden segmentation point. Calculating formula (5^0.5-1)/2 = (2.236-1)/2=0.618 R N, are you looking for this?

  2. Pay content for time limit to check for freenAnswer uses K gold to indicate the purity of gold with "K gold" to indicate that Huangquan purity gold jewelry is usually divided into foot gold and K gold. K (open) gold refers to the alloys made from a certain proportion of gold, silver, copper and other metals. K is a symbol used internationally to represent the purity (that is, the gold content). Generally speaking, the more the proportion of K gold is silver, the more colorful. If the copper ratio is large, the color is purple. In theory, we refer to the gold with a content of 100$K (24K gold is considered pure gold, but in reality does not have 100%pure gold); the calculation method is: per k = 100/24 ​​= 4.1666666%. National Standard: National Standard GB11887-89 stipulates that every K (abbreviation of English Carat and German Karat, often writing K) gold content is 4.1666666%. Calculated, after 1982, it has been unified with international standards, with a gold content of 4.66% per KnQuestion Gold Machining 20g flat chain, calculating formula
