load() function
It is possible to define reusable Maxima libraries with wxMaxima that can be later loaded by using the load() function. All that has to be done is to export a file in the .mac or to save it in the .wxm format. Note, though, that a few special characters like the "not equal" symbol for "#" are handled by wxMaxima, not by Maxima and therefore cannot be recognized on load().
load() 함수를 사용하여 나중에 로드할 수 있는 재사용 가능한 Maxima 라이브러리를 wxMaxima로 정의할 수 있습니다. 이 작업을 수행하려면 파일을 .mac으로 내보내거나 .wxm 형식으로 저장하기만 하면 됩니다. 하지만 "#"의 "같지 않음" 기호와 같은 몇 가지 특수 문자는 Maxima가 아닌 wxMaxima에서 처리하므로 load()에서 인식할 수 없다는 점에 유의하세요.

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: $$tT=∫t0texp[QR(1T0−1T(τ))]dτt_T = \int_{t_0}^{t} \exp \left[ \frac{Q}{R} \left( \frac{1}{T_0} - \frac{1}{T(\tau)} \right) \right] d\tau tT=∫t0texp[RQ(T01−T(τ)1)]dτ$$ 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...
