Using variational calculus, necessary conditions for boundarytemperature control of the reactors have been derived.
使用变分方法，推导了这类反应器边界温度控制的必要条件。

The temperature difference variation of model boundary shows the space gradient of temperature field, and the larger boundarytemperature difference requires higher order.
模型边界的温差变化表现了温度场的空间梯度，越大的边界温差需越高的计算阶数。

So if a scientist wanted to study the microorganisms living on each side of a temperature gradient, the AUV would find the boundary, follow it, and pick the best spot to take samples.
