The paper describes two methods of comparison of ship deep water resistance: (1) direct method of comparison and (2) comparison with "Standard Series" modelresistance charts.
本文首先简单地介绍了深水阻力的两种比较方法即（1）直接比较法和（2）通过与标准船型的阻力性能比较。

They found that they could, but the resistance in different switches behaved in a way that was impossible to predict using any conventional model.
他们发现他们可以制造出这样的开关，但是不同开关中电阻的运作，用传统的模型根本无法预测。

In handling resistance we were reminded on Kotter and Schlesinger's Six Approach model.
