Good design eludes definition, but you can usually recognize something that is well designed.雖然無法定義什麽才是"真正好的設計（GOOD DESIGN）"，但是妳卻能夠識別出那些設計巧妙的事物。

One characteristic of good design is that it is exactly righe for the specific application. 所謂“真正好的設計”的特點之壹在於這個設計能夠恰如其分地適用於具體的應用。

Everything necessary is present, but everything unnecessary is absent.必要的設計無所不有，而又摒除了所有不必要的設計。

The skills needed for good design entail experience, intuition, and esthetic sensibility. They are not easily learned from books.

這種能夠成就“真正好的設計”的技能需要經驗，直覺和對美學的敏感度來實現；而這些技能是很難從書本中學到的。

The most you ought to expect from any textbook on design (including this one) is to learn about some useful tools.妳從任何關於設計的課本（包括這本）中只能學到壹些有用的工具而已。

Like most books on control system design, this book presents tools that can be reduced to mathematical equations: analysis and simulation. 像大多數關於控制系統設計的課本壹樣，這本書主要講了壹些能夠被簡化為數學等式的工具：分析以及模擬。

Skill in the other aspects of design (such on time and money), which is as important as the mathematical analysis, is acquired and perfected through practical experience. 在設計學上，和數學分析這種技能同等重要的其他方面的技能（比如說在時間和金錢方面），是需要在實踐經驗中獲取和不斷趨向完美的.
