| 摘要: |
| 继电器接触式测波仪,由于使用了近百个继电器组及相应的电线和触头,显得相当笨重,在使用中还对其它同步测量的信号产生干扰;在此基础上发展的电阻接触式测波仪,在设计中需反复逐步实验才能达到直线性。而当盐度发生变化时还会产生不可忽视的非线性,因此使用上十分困难。根据上述问题,作者研制了新的等电阻接触式自动测波仪。 |

| Abstract: |
| In this paper, a new principle for measuring sea waves is suggested, and a wave recorder of equal-resistance contact type has been designed and constructed.
Results of laboratory experiments and field works prove that the linearity of this method is satisfactory, and meanwhile the zero-line can be recorded. It is suitable for measuring waves in different regions of the sea, and can be operated with synchronous measurement of other oceanic dynamic elements and without interference. Furthermore, in the electrical circuit, the connetive usage with recording system is considered. It provides, for the self-observation of sea waves, a simple and light instrument which is appropriate to manufacture by sets. |
