关于脈动流速的观測問題,在气流里面,已經圓滿解决;在清水水流里面,用速續摄影的方式,也得到了解决;在挾沙水流(渾水)里面,还没有很好地解决。为了适应我院关于挟沙水流和其他某些科学研究的需要,我組于1958——1959年,在我院党委和院行政領导下,貫彻执行党的教育方針,采取教师、学生、工人相結合的方式,試制成功应变式脈动流速傳送器梢员容^滿意地观测清水水流及挾沙水流(渾水)的脈动流速。本文对这种傳送器的结构和性能分别作了討論。另外,由于測量的需要,我們还試制了电子測量仪器,本文对这种測量仪器也作了簡单的介紹。
The problem of the observation of the pulsating flow velocity has been satisfactorily solved in the air flow; it has also been solved by means of continuous photography in clear water flow; and it has not yet been well solved in sediment-laden flow (muddy water) . In 1958-1959, under the leadership of the party committee and the hospital in our college, in order to meet the needs of our hospital on sediment-laden flow and other scientific research, we implemented the party’s education policy and adopted teachers, students, Workers combined with the trial, the successful trial of strain-type pulsatile flow transmitter Tip member content ^ satisfactorily observe the water flow and sediment-laden water flow (muddy water) pulsating flow rate. This article discusses the structure and performance of this transmitter separately. In addition, due to the needs of the measurement, we also trial electronic measuring instruments, this article also made a brief introduction of such measuring instruments.
