项目摘要

From investigated results of the research title proposed by us, following conclusions can be drawn:(1) As for the speed-sensor using Coriolis force due to earth self-revolution phenomenon for some bodies running on earth, it is found clear from the results of some trials that following two sensor-constructions had a potentiality to be performed: One is to apply the high-grade digital pressure meter in which a dual quartz crystal tuning fork resonator is equipped to detect the Coriolis force, and the other is to use revolution of a mass-added piezoelectric cantilever type transducer for detection of Coriolis force due to earth revolution.(2) Experiments on the pressure meter type speed-sensor were done not only by its running in a long passage in a building, but also by setting in a vehicle running on a public road. The results were that basic functions as a speed meter could surely be confirmed, but some scattering were found in the measured data at the test in a running vehicle.Such s … More cattering might be influenced by some kinds of shocks from the vehicle, and so this phenomenon is a problem solved in the future.(3) As for the speed-meter of a mass-added piezoelectric transducer revolution type, its performance is now in about 80% degree, however this type speed-sensor is clearly promising because its construction is very simple and so it will be made more miniature-sized, and then it is supposed that the electronic circuit for detection of Coriolis force is simple, too.Hereafter, the research of this sensor must be more performed.(4) On the process of research of such a speed sensor, such by-products as a high sensitive quartz crystal gyro-sensor of flat type, 3-axis angular-velocity detection type gyro-sensor and one chip style motion-sensor can be developed, too.The speed-sensor mentioned above is not individually used, but it can function when it will be practically used in cooperation with such gyro-sensors and so on. From this meaning, development of some sensors mentioned above must be understood very important. Less

从我们提出的研究题目的调查结果中，可以得出以下结论：(1)对于一些在地球上运行的物体，利用地球自转现象产生的科里奥利力的速度传感器，从一些试验的结果中可以清楚地发现，以下两种传感器结构具有实现的潜力：一种是采用配备双石英晶体音叉谐振器的高级数字压力表检测科里奥利力，另一种是采用加质量压电悬臂式传感器的转数检测地球公转引起的科里奥利力。(2)对压力表式速度传感器进行了在建筑物长通道内运行的实验，以及在公共道路上运行的车辆上的设置实验。结果表明，作为测速仪的基本功能是可以肯定的，但在车辆运行试验中，测量数据存在一定的散射。更多的餐饮可能会受到来自车辆的某些冲击的影响，所以这种现象是未来要解决的问题。(3)添加质量的压电式转速传感器，其性能目前仅为80%左右，但由于其结构简单，因此将进一步小型化，因此这种类型的转速传感器显然是有前途的，然后假定用于检测科里奥利力的电子电路也很简单。今后，对该传感器的研究还需进一步深入。(4)在这种速度传感器的研究过程中，还可以开发出高灵敏度的平板型石英晶体陀螺传感器、三轴角速度检测型陀螺传感器和单片式运动传感器等副产品。上面提到的速度传感器不是单独使用的，但实际使用时，它可以与陀螺仪等传感器配合使用。从这个意义上说，上述一些传感器的发展是非常重要的。少
