| 7. | Narrowband watermarking information is spread into wideband pseudo - random code before being embedded by modifying the scale of the distance between vertexes in two - dimensional engineering graphics 该方案先将待嵌入的窄频带的浮水印信号扩频为宽频带的伪随机序列,然后再以伪随机序列为依据对二维工程图中直线实体的长度作相应的修改。 |
| 8. | The radar based on this system can go beyond the limit of continuous silent frequency band . if there are some extent non - continuous silent frequency band in certain range , and its sum can fulfill the demand of the signal bandwidth , the radar will be work well 这种体制的雷达可以突破连续寂静频带的限制,只要在一定范围内存在一定数量的非连续寂静窄频带,其总和满足信号带宽要求,就可以使雷达正常工作。 |
| 9. | To reproduce the narrow - band response , based on the thought of kanamori etc . , the damping ratio and natural period are modified . through this adjustment , the narrow - band response can be reproduced , but for some natural periods the adjustive damping ratio has become negative . the negative damping is strange and can not be explained by the equation of motion for sdof system 为了生成窄频带反应,本文根据kanamori等人的方法调整了计算时的阻尼比及自振周期,调整后的单边差分方法能在共振区域生成很好的窄频带反应,但是对一些周期点的阻尼比调整成为了负值,这从系统的动力平衡方程是难以解释的。 |
| 10. | From some characteristics observed , such as the short lift time , narrow frequency band , fast frequency drift , quasi - periodic pulsation , spike event and complex magnetic structure , it is considered that the radiation mechanism of these events may be principally due to the electromagnetic waves magnified directly by the instable electronic cyclotron 从它们的观测特征:短寿命,窄频带,频率快速漂移,及尖峰事件与磁结构复杂的大黑子活动区密切相关等,认为这些事件的辐射机制可能是电子回旋脉泽不稳定直接放大电磁波所致。 |
