1.1 This specification covers lead sheet, strip, and plate of various alloys intended for use in chemical plants, sound attenuation, roofing, vibration dampening, flashing and weather stripping, waterproofing, and radiation shielding.

1.2 The values stated in inch-pound units are to be re...

1.1 This test method permits the rapid measurement of apparent relative permittivity and loss tangent (dissipation factor) of metal-clad polymer-based circuit substrates in the X-band (8 to 12.4 GHz).

1.2 This test method is suitable for testing PTFE (polytetrafluorethylene) impregnated gl...

1.1 This test method covers the nondestructive determination of thickness of bound pavement layers using short-pulse radar.

1.2 The accuracy and applicability of this test method is a function of these components: radar-system penetration, radar-system resolution, and the dielectric const...

Parallel calculational methods were used to analyze incompressible turbulent flow through hydraulic machinery. Two parallel methods were used to simulate mulate the complex flow field. The space decorrposition method divides vides the computational domain into several sub-ranges. Parallel discrete e...

In this paper, the stability analysis for parallel real-time digital simulation models is discussed. The coupling coefficient perturbation method and the simulation stepsize perturbation method are established. For two classes of systems of test equations, we construct the parallel simulation models...
