| 摘要 |
A dielectric probe for use with conventional frequency and time domain impedance analyzers comprises two chemically resistant electrodes deposited in an interdigitated pectinate configuration on particular non-conductive substrates, the spaces between the digits thereof being no greater than about 0.01 inch; methods and apparatus for monitoring and/or controlling chemical reactions, particularly polymerization reactions, in contact therewith, wherein the complex permittivity may be calculated over a wide range of frequencies and temperatures.
