circular slide rule造句

• Also a variety of elementary equipment for a chemical laboratory : a circular slide rule.
• Otherwise, it can be performed with a calculator such as the E6B handheld circular slide rule.
• Proportion wheels are simple circular slide rules used in graphic design to broaden or slim images and photographs.
• Another drawback of circular slide rules is that less-important scales are closer to the center, and have lower precisions.
• The main disadvantages of circular slide rules are the difficulty in locating figures along a dish, and limited number of scales.
• The E6B circular slide rule used by pilots has been in continuous production and remains available in a variety of models.
• Otherwise, it can be performed using this applet or a device such as the E6B ( a handheld circular slide rule ).
• The bomb sight was also supplied with the Emergency Computor, a simple circular slide rule for use when the main computor stopped working.
• Dalton's first popular computer was his 1933 Model B, the circular slide rule with True Airspeed ( TAS ) and Altitude corrections pilots know so well.
• The RDP was developed by circular slide rule version called The Wheel, followed by the eRDP, an electronic version introduced in 2005 and the eRDPML, an electronic multi-level version introduced in 2008.
• The basic advantage of a circular slide rule is that the widest dimension of the tool was reduced by a factor of about 3 ( i . e . by ? ).
• One slide rule remaining in daily use around the world is the E6B . This is a circular slide rule first created in the 1930s for aircraft pilots to help with dead reckoning.
• His original design of some time in the 1620s was for a circular slide rule; but he was not the first into print with this idea, which was published by Delamain in 1630.
• Alternatively, the E6B flight computer ( a circular slide rule with a translucent " wind face " on which to plot the vectors ) can be used to graphically solve the wind triangle equations.
• Calculating the proper drift angle is a simple task of basic vector addition, and is commonly carried out on a circular slide rule like the E6B . This is a somewhat time consuming process.
• Circular slide rules also eliminate " off-scale " calculations, because the scales were designed to " wrap around "; they never have to be reoriented when results are near 1.0 the rule is always on scale.
• Circular slide rules are mechanically more rugged and smoother-moving, but their scale alignment precision is sensitive to the centering of a central pivot; a minute 0.1 mm off-centre of the pivot can result in a 0.2mm worst case alignment error.
• The U . S . Army Air Corps decided the endless belt computer cost too much to manufacture, so later in 1937 Dalton morphed it to a simple, rigid, flat wind slide, with his old Model B circular slide rule included on the reverse.
• Once data were available on wind speed and direction, a circular slide rule-like device called a "'wind component indicator "'( see the left-most image below ) was used to figure out the components of the wind that affected either the range or the deflection ( direction ) of the shells fired.
• :I'm not sure I get what you mean by a circular layout, but it seems like you basically want something like a circular slide rule-- since area equals length times width, you need a mechanical way of doing multiplication; a slide rule does that by adding logarithms . talk ) 23 : 40, 9 March 2010 ( UTC)
