方向指示器

The BDHI Indicator is used to display Bearing Distance Heading of the aircraft to a designated beacon or desired destination with pointers driven by synchros and with the use of integral lighting, servoed pointers and compass card in connection with TACAN and VOR systems.

该BDHI指示器是用来显示飞机对于一个指定的信标或期望的目的地的定位距离方向，指针由自整角机驱动，具有内置照明，伺服指针和罗盘刻度盘，可与TACAN和VOR (伏尔，甚高频全向无线电信标)系统连接。

UDZ Series liquid level indicator of flap disassembly fast and convenient, the installation position can be arbitrary choice, free to change the direction of observation, thus instrumented great visibility; UDZ series of cost-effective liquid level was significantly higher than that used multiple sets of glass plate liquid level of cost performance; UDZ series of liquid level indicator, the sender's device, as well as the liquid level with the main transmission medium within the complete separation of the measured structural design, so that level gauge in the job has pressure (up to 320KG), toxic and inflammable conditions, with absolute safety and reliability; UDZ-3 type uses innovative design, improve the sensitivity of the sensor, and its near-zero drift FarEasTone signals and long-term stability so that it has always been at the scene consistent level instructions; sensors and the main body has a certain interval, which can be solved effectively under high-temperature liquids (up to 480 ) remote detection and control; antifrost type UDZ Series Level Gauge, are I plant the patented product (Patent No.: ZL00221022 3), guarantees that the use of cryogenic liquid level gauge is not freezing (such as liquid CO2), the effective guarantee of the level of a normal job.

UDZ系列液位计的翻板指示器拆装快捷方便，安装方位可任意选择，观察方向可随意改动，因而仪表指示的可视度很大；UDZ系列液位计的性能价格比明显高于采用多组玻璃板式液位计的性能价格比；UDZ系列液位计的指示器，发讯器、以及液位变送均与主体内被测介质完全隔离的结构设计，使液位计工作在有压（可达320KG）、有毒和易燃的工况下，具有绝对的安全性和可靠性；UDZ-3型采用了新颖设计，提高了传感器的灵敏度，其远传信号近乎零温漂和长期稳定性使其始终于现场液位指示保持一致；传感器和主体有一定的间隔，因而能有效地解决高温液体（可达480℃）远距离检测和控制；防霜型UDZ系列液位计，是我厂的专利产品（专利号：ZL00221022·3），保证了在低温液体上使用液位计不结冰（如液体CO2），有效的保证了液位计的正常工作。

The at least one data retention indicator device (50) comprises a first magnetic element (51) and a second magnetic element (52) each having a pre-set magnetisation direction, the pre-set magnetisation direction of the first and second magnetic elements (51, 52) being different from each other.

该至少一个数据保持指示器器件(50)包括第一磁性元件(51)和第二磁性元件(52)，这两个磁性元件中每个都有预置的磁化方向，所述第一和第二磁性元件(51，52)的预置磁化方向互不相同。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
