    摘要： An improved polishing pad is provided comprising a solid uniform polymer sheet having no intrinsic ability to absorb or transport slurry particles having during use a surface texture or pattern which has both large and small flow channels present simultaneously which permit the transport of slurry across the surface of the polishing pad, where said channels are not part of the material structure but are mechanically produced upon the pad surface. In a preferred version of the invention, the pad texture consists of a macrotexture produced prior to use and a microtexture which is produced by abrasion by a multiplicity of small abrasive points at a regular selected interval during the use of the pad.

    摘要： Apparatus for withdrawing a gas from a source and conditioning the gas for subsequent analysis for total reduced sulfur content comprising a gas probe having an inlet for a stream of gas and an outlet therefor, a conduit having means to provide heat to a gas stream flowing therein extending from the probe outlet to a condenser for cooling the gas and condensing out water, a second conduit from the condenser to a vacuum which causes a gas stream to enter the probe and flow through the heatable conduit to the condenser and then the second conduit, a third conduit for delivering a stream of gas from the second conduit to a scrubber to wash the gas stream with a scrubbing liquid, a demistor for removing the gas stream from the scrubber and separating entrained scrubbing liquid, and a pump for pumping the scrubbed gas stream, from which scrubbing liquid has been removed, to an analyzer and flow meter.A method of conditioning the gas for analysis using the apparatus is also disclosed.
