so now we're going to look at the 所以现在我们要看看
boundary layer the first thing that 第一件事就是边界层
we're going to do is create another 我们要做的是创造另一个
contours plot let's call this mock 轮廓图让我们称之为模拟
contours symmetry we're going to want 等高线对称我们将要
this on the near side the variable is 这在变量的附近
going to be Mach number and again for 将成为马赫数，并再次为
the rendering turnoff lighting go back 渲染关闭照明返回
to geometry and we'll just have 25 几何，我们只有25
contours this time hit apply let's turn 轮廓这次点击适用轮到我们了
off the pressure coefficient contours 关闭压力系数等值线
and the Mach number contours now we're 现在我们是马赫数轮廓
going to turn on the pressure 要打开压力
coefficient contours in this imagery as 这个图像中的系数轮廓为
well click on the z axis and we'll zoom 以及点击z轴，我们将放大
in so here's our shock we zoom in a 在这里我们的震撼我们放大了
little bit more to this region you can 你可以在这个地区稍微多点
see how right here we have our thin 看看这里我们有多瘦
boundary layer and the boundary layer 边界层和边界层
thickens 变稠
after the shock if you'd like to better 如果你想要更好的话，在震惊之后
view the divisions between the contours 查看轮廓之间的分隔
if we go back to mock contour symmetry 如果我们回到模拟轮廓对称
in render you can expand this tab here 在渲染中你可以在这里展开这个选项卡
and hit constant coloring apply and that 并打不断着色适用和那
makes the lines black so you can better 使线条变黑， 所以你可以更好
see the divisions you can of course 当然可以看到你可以分开的部门
increase the number of contours as well 增加轮廓的数量
you can see thickening of the boundary 你可以看到边界的增厚
layer and the thin boundary layer before 层和薄边界层之前
the shock 震惊
