wxmaxima.rc

 wxMaxima can be made to execute commands at every start-up by placing them in a text file with the name wxmaxima.rc in the user directory. This directory can be found by typing maxima_userdir;


사용자 디렉터리에 wxmaxima.rc라는 이름의 텍스트 파일에 명령을 저장하여 시작할 때마다 명령을 실행하도록 wxMaxima를 설정할 수 있습니다. 이 디렉토리는 maxima_userdir을 입력하면 찾을 수 있습니다;

Temperature effects_maturity

  In the   CEB-FIP Model Code 90 ,   maturity   is a concept used to predict the rate at which concrete gains strength based on temperature and time.   Eq. (2.1-87)   is used to calculate the   maturity-adjusted time  $$ t_T$ $​ , which accounts for the effects of temperature on concrete's strength development. \(  S=\int d^{4} x\left(\frac{R}{2 \kappa}\right) \) begin{eqation} S=\int d^{4} x\left(\frac{R}{2 \kappa}\right) end{equation} Definition of Equation (2.1-87): The maturity-adjusted time $$tTt_T tT​$$  is calculated as: $$tT=∫t0texp⁡[QR(1T0−1T(τ))]dτt_T = \int_{t_0}^{t} \exp \left[ \frac{Q}{R} \left( \frac{1}{T_0} - \frac{1}{T(\tau)} \right) \right] d\tau tT​=∫t0​t​exp[RQ​(T0​1​−T(τ)1​)]dτ$$ Where: tTt_T tT​  = maturity-adjusted time (in days) tt t  = real elapsed time (in days) t0t_0 t0​  = start time for the calculation (usually 0) QQ Q  = activation energy for hydration process, typically around 33,500 J/mo...
