logarithmic unitsの例文

• The standard system for comparing interval sizes is with logarithmic unit of measurement.
• See logarithmic units for logarithms taken in different bases.
• Some people use a logarithmic unit for big or small positive numbers to emphasise the important parts.
• Regrettably there is no commonly used name for the logarithmic unit corresponding to the " percent ".
• The formulae in this article are exact if logarithmic units are used for relative changes, or equivalently if logarithms of indices are used in place of rates, and hold even for large relative changes.
• A "'logarithmic unit "'is an abstract mathematical physical or mathematical ) that is defined on a logarithmic scale, that is, as being proportional to the value of a logarithm function.
• The "'neper "'( unit symbol "'Np "') is a logarithmic unit for ratios of measurements of physical field and power quantities, such as gain and loss of electronic signals.
• A "'sound limiter "'or "'noise limiter "'is a digital device fitted with a microphone to measure the sound pressure level of environmental noise, expressed by the decibel logarithmic unit ( dB ).
• Here, a given logarithmic unit will be denoted using the notation [ log " n " ], where " n " is a positive real number, and [ log ] here denotes the indefinite logarithm function Log ( ).
• These approximations, valid only for small changes, can be replaced by equalities, valid for any size changes, if logarithmic units are used, notably centinepers, which are infinitesimally equal to percentages ( approximately equal for small values ); other logarithmic units differ by scale factors.
• These approximations, valid only for small changes, can be replaced by equalities, valid for any size changes, if logarithmic units are used, notably centinepers, which are infinitesimally equal to percentages ( approximately equal for small values ); other logarithmic units differ by scale factors.
• Most elegantly, if the natural logarithm is used, yielding the neper as logarithmic units, scaling by 100 to obtain the centineper yields units that are infinitesimally equal to percentage change ( hence approximately equal for small values ), and for which the linear equations hold for all values.
• Both the apparent and absolute magnitude scales are logarithmic units : one whole number difference in magnitude is equal to a brightness variation of about 2.5 times ( the second magnitude ( + 2.00 ) star, and about 100 times brighter than a sixth magnitude star ( + 6.00 ).
• Thus, we can interpret Boltzmann's constant as being simply the expression ( in terms of more standard physical units ) of the abstract logarithmic unit [ log e ] that is needed to convert the dimensionless pure-number quantity ln " W " ( which uses an arbitrary choice of base, namely e ) to the more fundamental pure logarithmic quantity Log ( " W " ), which implies no particular choice of base, and thus no particular choice of physical unit for measuring entropy.
