科学计算的官方活动群,可以加一下

\frac{\partial^2T}{\partial x^2} + \frac{\partial^2T}{\partial y^2}=0
$$

其中,$T$ 表示温度分布,传统的求解方法涉及使用数值方法如有限元法或有限差分法,这些方法通常需要离散化领域并求解大规模矩阵系统。近年来,基于物理信息的神经网络(Physics-informed neural networks, PINN)逐渐成为求解偏微分方程的新方法。PINN 结合了神经网络的灵活性和对物理约束的建模能力,能够直接在连续领域中解决偏微分方程问题。

热传导是自然界中的常见现象,广泛应用于工程、科学和技术领域。了解和模拟传热过程对于设计和优化热传导设备、材料和系统至关重要。2D 定常传热方程描述了稳态热传导过程,其数学表达形式为:

$$
\frac{\partial^2T}{\partial x^2} + \frac{\partial^2T}{\partial y^2}=0

请全文检查一下,公式中也需要有标点符号

没有理解“公式中也需要有标点符号”是啥意思
