The controllability and observability of a system over F always means the controllability and observability of the system over the field R of real numbers.

一个F上的系统是能控能观的，即结构能控能观的，则意味着实数域上该系统实际上总是能控能观的。

And we know by study, so long as system is controllable and observable at the structure over the field F(z of the rational functions in multi-parameters, it is always controllable and observable over the field R of real numbers.

通过研究我们知道，一个系统只要在结构上多元有理函数域(F上是能控能观的，则意味着实数域上该系统实际上总是能控能观的。

The workload is enormous and it is very difficult to guarantee the exactness of the result, so it is very valuable to develop a set of computer-assisted software for founding the state equations and analyzing the correlative properties of system over the field F of the rational functions in multi-parameters.

因此，开发一套建立F上系统状态方程系并能进行相关性质分析的计算机辅助软件便极有价值。

For any RLC electric network given, the software can found its state equation over the field F of the rational functions in multi-parameters very swiftly and effectively, and can analyze its controllability automatically. Moreover there is not any additive restriction for its complexity.

对任意给定的RLC电网络均能十分快捷有效地生成其在F上的状态方程，并能对其能控性进行自动分析判别，而对其复杂程度没有任何附加限制。

The F-22 flew much as I expected it to fly like a fighter plane.

F-22的表现与我所期盼着去飞的战斗机几乎别无二致。

He then served two tours as a fighter-bomber pilot during the Korean War flying the Republic F-84 Thunderjet.

之后他作为战斗轰炸机飞行员驾驶F-84雷电喷气机在韩战中执行了两次任务。

The last version, the Bf 110G, was intended for use originally as a fighter-bomber but, in view of the success of the F-4 and the increasingly heavy attacks on Germany by Allied bombers, was employed mostly as a night fighter.

最后版本，高炉110g，是打算利用原作为战斗轰炸机，但鉴於成功的F-4和日益沉重的攻击，德国的盟军轰炸机被聘用，大都作为一种夜间战斗机。
