应当进一步注意到的是本案中专利权所有人以列举的方式，画出了一个他所说的烟灰缸的结构草图。

It is further to be observed in this case that the patentee does show a drawing illustrating, as he says, one construction of the ash-tray by way of example.

换句话说，专利权所有人没有告诉世人，他所提及的各个部分应限制于一个什么样的相对比例才会产生预期的结果。

In other words, the patentee does not tell the world within what limits the relative proportions of the integers he has mentioned must be kept to produce the desired result.
