查询词典 sealer

The new method is a combination of characteristic approximation to handle the convection part, to ensure the high stability of the method in approximating the sharp fronts and reduce the numerical diffusion, a smaller time truncation is gained at the same time, and a mixed finite elementspatial approximation to deal with the diffusion part, the sealer unknown and the adjoint vector function are approximated optimally and simultaneously.

此方法即为对方程的对流项沿流体流动的方向即特征方向进行离散，从而保证格式在流动锋线前沿逼近的高稳定性，消除了数值弥散现象，并得到了较小的时间截断误差；另一方面，对方程的扩散项采用混合元离散，可同时高精度逼近未知函数及其伴随向量函数，理论分析表明，此方法是稳定的，具有最优的L~2逼近精度。

You're just going to have to step it up a little: replace that liquid-measuring cup with a more accurate dry-weight scale; get a vacuum sealer like that FoodSaver gadget and a Crock-Pot that stays at a precise temperature so you can sous vide meat (which involves cooking it in a bag for a long time in a low-temperature water bath); learn how to use simple chemicals like agar-agar and xanthan gum (just better versions of gelatin and cornstarch, really); review a little high school chemistry.

你只需要循序渐进的学习：用更精确的干重测量代替液体量杯；准备一个真空密封器如FoodSaver，还有Crock-Pot，它可以让你保持准确的温度，这样你就可以随时调整肉的情况（包括放在袋子里用低温水煮食的肉）；学习怎么使用一些简单的化学品，如洋粉、黄原胶（实际上是明胶和太白粉的升级版）；复习一下高中化学。
