scaling ratio การใช้

• The scaling operation is performed with different scaling ratios in different parts of the image, according to the defined transformation.
• Proto and finescale rails and wheels are generally not compatible with the normal scale model railway material with the same scale ratio.
• The following chart shows the types currently understood by GeoHack, the scale ratio associated with each, plus the additional variables calculated by GeoHack.
• The number 10 is actually a scale ratio of two lengths 10 / 1m, where 10 is the measured quantity, and 1m is the arbitrary defining unit.
• Even in dealing with 2D drawings, the manufacturing world has changed since the days when people paid attention to the scale ratio claimed on the print, or counted on its accuracy.
• These standards are generally the same for such elements as track gauge, scale ratio, couplings, and electrical power, and differ for clearances and other factors that are specific to the prototype being modelled.
• The Germans have a more developed terminology, which can explain this a bit better . " Baugr鰏se " ( English : " building size " ) is the alphanumeric designation, which is used in place of a numeric scale ratio.
• Moreover, an arbitrary scale " e " doesn't have any physical meaning in itself ( like the number 10 ), only scale ratios r = e'/ e have a meaning, in our example, r = 10 / 1.
• This loss of units results from the use of a scaling ratio with respect to a carbon-12 standard, and the word " relative " in the term " relative isotopic mass " refers to this scaling " relative " to carbon-12.
• In the past, prints were plotted on a plotter to exact scale ratios, and the user could know that a line on the drawing 15mm long corresponded to a 30mm part dimension because the drawing said " 1 : 2 " in the " scale " box of the title block.
• Today, in the era of ubiquitous desktop printing, where original drawings or scaled prints are often scanned on a scanner and saved as a PDF file, which is then printed at any percent magnification that the user deems handy ( such as " fit to paper size " ), users have pretty much given up caring what scale ratio is claimed in the " scale " box of the title block.
