| 1. | The vertical tail size is not set to avoid spiral instability because this mode is not critical .
垂尾的大小不是根据避免螺旋不稳定来确定的。因为这种运动模态不是设计状态。 |
| 2. | The use of the free undamped normal modes is seen to ensure that the linear and angular momenta of the distortional motion vanish .
看来采用自由无阻尼正规模态可保证变形运动的线动量和角动量为零。 |
| 3. | Interpretation of the relative importance of the higher modes is difficult since the higher frequencies tend to be closely spaced .
较高模态的相对重要性的说明也是困难的，因为较高的频率趋于挤在一起。 |
| 4. | One significance of the eigenvectors is seen to be that they determine the values of the state variables in a characteristic mode .
本征矢量的重要意义之一是，它们决定了在一定模态中状态变量的相对值。 |
| 5. | We find that there are reasonable approximations to all three modes, but the application of all such approximations must be made with caution .
我们发现，三种模态都有适当的近似式，但应用它们必须谨慎。 |
| 6. | This will help to overcome problems of apparent bimodality caused by the presence of many below-detection-limit values in a data set .
这将有助于克服因数据组中有大量低于捡出限的数值而出双模态性的问题。 |
| 7. | Apparent multimodality of the distribution, or lack of it, is often an artifact of the size and nature of the area mapped .
明显的多模态分布的存在或不存在，往往是一种因编图区大小与性质的关系搞成的人为产物。 |
| 8. | Although modal techniques have had standard acceptance in treating mechanical and structural vibrations, they have not been used generally to simulate fluid system .
尽管模态技术在处理机械和结构振动中已经普遍公认了，但这种方法还未普遍应用于模拟流体系统。 |
