उदाहरण वाक्य

1. Finally, the scale number " L6 " indicates a lower limit for the optical density, i . e . the transmittance within this wavelength range is less than 10  " 6.
2. In 1949, E . Racker defined one unit of alcohol dehydrogenase activity as the amount that causes a change in optical density of 0.001 per minute under the standard conditions of assay.
3. In quantitative ELISA, the optical density ( OD ) of the sample is compared to a standard curve, which is typically a serial dilution of a known-concentration solution of the target molecule.
4. In the AAS method, to determine multianalytes on a DVD, the analog signals acquired directly from the photodiode of a CD / DVD drive correlate well with the optical density of the reaction products.
5. The progress of the flame front across the test material is measured by visual observation, while the smoke emitted from the end of the test assembly is measured as a factor of optical density.
6. Therefore, a typical fully grown 1-liter culture of " Escherichia coli " ( at an optical density of 1.0, corresponding to ca . 10 9 cells / ml ) yields about 1 g wet cell mass.
7. The method is described in details in Liukaityte et al . paper from Optics Letter and allowed to study thin-film filters with optical densities from 0 to 12 in a wavelength range between 400 and 1000 nm.
8. Small sections of very dark aluminum coated glass attenuation filters ( which have the appearance of mirrors due to their extremely high optical density ) on the front of a telescope provide safe observation through the eyepiece.
9. The failure results when the optical density of the employed toner reaches the highest value it can provide, when a perfect line of change is visualized in the printed graphic and a substantial reduction of said density follows.
10. In addition to an optical density sufficient to reduce beam power to below the maximum permissible exposure ( see above ), laser eyewear used where direct beam exposure is possible should be able to withstand a direct hit from the laser beam without breaking.
