| 1. | These probes include a small electrical heater which is supplied from a small battery in the pressure case . 这些探头各有一个在加压情况下由小蓄电池供电的小型电热器。 |
| 2. | To protect magnetic field sensors from intense erosion and high pressure , suitable sealed pressure cases must be designed 其中之一是如何将磁场传感器运抵海底实施测量。 |
| 3. | However , it doesn ' t mean that the sealed pressure case made by lc4 will be perfect in performance Lc4超硬铝合金在可选的材料中性价比居高,然而用它制成的高压密封舱并非十分完美。 |
| 4. | Experiment results suggest that the response distortion induced by the sealed pressure case appears in the mid and high frequency area 实验结果揭示,由高压密封舱引起的频响变异发生在中高频区段。 |
| 5. | Considering the magnetic measurement and seafloor operation , the sealed pressure case should be nonmagnetic and transportable 为抵御海水的侵蚀和抗衡海下的环境压力,需要研发装载磁场传感器的密封舱。 |
| 6. | In fact , because of its weak magnetism , the pressure case made by lc4 has distorting effect on frequency responses of the magnetic field sensors sealed in it 因它的弱磁性,使得磁场传感器装入舱体后,整体频率响应发生了部分变异。 |
| 7. | 1 horizonal vessel with saddle support 2 vertical vessel with ear - lug , skirt , leg support 3 special structure used in very high pressure case 当前对于压力容器中最重要的工艺焊接,是关系到压力容器质量的重要工艺环节,有相应的标准: |
| 8. | In our experimental tests , we used frequency swept magnetic field as excitation signal , and then measured responses of the magnetic field sensor before and after being loaded in to the sealed pressure case 在所构思的实验装置中,通过人为产生扫频磁场,对密封和非密封条件下的磁场传感器进行激励。 |
| 9. | Ultimately , we obtained normalized abnormal curves for the frequency responses , through which we could reveal hew the sealed pressure case impacts the responses of the magnetic field sensor 在响应输出端,测取幅频特性和相频特性,获得归一化的对比资料和频响异常曲线,从而对密封前后磁场传感器的性能变化有较清楚的认识。 |
