为探讨天津激光研究所发明的新型He-Ne激光管着火电压降低的机制
本文用特制的三种管子(普通型、改进一型、改进二型)和七种气体(He、Ne、He-Ne、Ar、Kr、H

及N

)进行了实验研究。结果表明:改进型管的着火电压低
但其电压降低的效应仅发生在一定的压强范围
当压强增至某一值P

电压降低值趋近于零

值视气体种类而定。并对实验结果作了理论解释。
For the Purpose of studying the mechanism of lowering breakdown voltage in the new type(Tian Jin type) He-Ne Laser
three kinds of tubes (the common type
the new type I and new type I) were made and breakdown voltage measurements were performed in several gases (He
Ne
He-Ne
Ar
Kr
H2
and N2). The experimental results show that the breakdown voltage for the new types is fairly lower than the common one
but this effect occurs only within a definite range of gas pressure. As the pressure increases to a certain value P0
which depends on what gas is used
the lowering effects vanish. A theoretical explanation for the experimental results is given.
