helical line

基本解释

The relations between dielectric, numbers of circles and the characteristic parameters of the helical line were studied.
通过实验研究了充电介质、螺旋匝数及形成线结构与螺旋脉冲形成线特性参量间的数值关系。
The influence of the impedence mismatching between the joint section in pulse forming line and the helical line on the voltage waveform of the diode was analyzed.
为消除输出脉冲的前沿上冲和后沿拖尾现象，分析了脉冲形成线中的连接段与螺旋线阻抗的不匹配对输出波形的影响。
Helical line (port) is in upstream of tangential port, minimizes the deterioration came from outflow of helical line, and obtains the best support of tangential port airflow.
螺旋线（气道）位于切向气道的上游，以使来自螺旋线外流的恶化减至最小，并获得切向气道气流的最佳支持。
