Temperature-Induced Stresses in Solids of Elementary Shape

Temperature-Induced Stresses in Solids of Elementary Shape

Date: June 21, 1960
Creator: Adams, Leason H.
Description: Report discussing how solids subjected to non-uniform temperature change develop internal stresses determined by, (1) the temperature distribution within the solid, and (2) certain physical constants of the material. For two varieties of heating, the equations determining stress have been put in convenient form for practical use, and tables of certain temperature functions show how to determine stresses in a slab, in a cylinder, or in a sphere subjected to either of two modes of heating. The temperature-distribution tables independently provide a useful means for the ready estimation of temperature gradients.

A Spectrophotometric Atlas of the Spectrum of CH from 3000A to 5000A

A Spectrophotometric Atlas of the Spectrum of CH from 3000A to 5000A

Date: February 14, 1961
Creator: Bass, Arnold M.
Description: Report of the near ultraviolet and visible emission spectrum of CH presented in the form of a spectrophotometric atlas. The spectrum was recorded photoelectrically from an acetylene-oxygen flame in the region 4900 to 3000 A by use of a high-resolution grating monochromator. Each of the lines in the CH spectrum is identified.

Causes of Variation in Chemical Analyses and Physical Tests of Portland Cement

Causes of Variation in Chemical Analyses and Physical Tests of Portland Cement

Date: April 27, 1961
Creator: Bean, B. Leonard
Description: Report discussing variations in comparative tests of portland cements that could lead to the rejection of a material fully conforming to specification requirements, or the acceptance of a material with undesirable chemical or physical properties. Many of the causes for variation in chemical analyses and physical test results are listed in this discussion, and remedies for some of the more frequently encountered deficiencies in apparatus and methods are suggested.

Radio Meteorology

Radio Meteorology

Date: March 1, 1966
Creator: Bean, B. R.
Description: Report compiling the work done in radio meteorology over the past ten years at the National Bureau of Standards' Central Radio Propagation Laboratory (CRPL). There is an emphasis upon the effects of the lower atmosphere on the propagation of radio waves. The CRPL group has concentrated upon the refraction of radio waves as well as the refractive index structure of the lower atmosphere on both synoptic and climatic scales. Additional chapters on radio-meteorological parameters and the absorption of radio waves by the various constituents of the lower atmosphere.

Microwave Attenuation Standards and Measurements

Microwave Attenuation Standards and Measurements

Date: April 3, 1967
Creator: Beatty, Robert W.
Description: Report discussing microwave attenuation measurement methods and standards. In addition, a relatively new and more precise way of representing and analyzing an attenuation measurement is presented. This in turn permits more rigorous definitions and error analyses than were previously possible. The referral of microwave attenuation measurements to standards operating at lower frequencies is discussed with particular attention to the errors in the referral processes as well as the errors in the standards themselves. Desirable characteristics are listed for attenuators which are suitable for calibration. Measurement methods are classified and described. Comments are made on the accuracy and convenience of various methods, and references are given which cover most of the basic and important research in this field. Key words: Microwave, attenuation, measurements, standards, tutorial.
