Because we are ignoring changes in spectral distributions at different levels in the vegetation,QinEquation 4.1can also be measured as the radiant energyflux densityfor these photons. 4.2.2Considerations for specific canopies The foliar absorption coefficient ranges from 0.3 to 1.3 for the majority of...
MAGNETIC FLUX DENSITY MEASURED IN FAST AND SLOW SOLAR WIND STREAMS The radial component of the heliospheric magnetic field vector is used to estimate the open magnetic flux density of the Sun. This parameter has been calcu... G. Erdős,A. Balogh - 《Astrophysical Journal》 被引量: 11发表:...
aThe heat flux density was measured by readings of the value of electric current through the heater and of the potential difference between terminals at the ends of the working sections. 热流密度由电流的价值的读书测量通过加热器和的终端之间的电位差在运作的部分的末端。[translate]...
the total magnetic induction crossing a surface, equal to the integral of the component of magnetic induction perpendicular to the surface over the surface: usu. measured in webers or maxwells. [1895–1900] Random House Kernerman Webster's College Dictionary, © 2010 K Dictionaries Ltd. Copyrigh...
Where φSkin Model is the heat flux density measured by the Skin Model (W/m2), and Vfluxmeter is the output voltage measured by heat fluxmeter (V). The greater the gradient of the curve, the greater the sensitivity of the heat fluxmeter. View chapterExplore book Techniques for measurement ...
CONSTITUTION:A device is provided with a superconductive quantum interferometer (skid) 1 at its upper part and a pickup coil 3 composed of a printed coil is arranged nearby a material 2 to be measured. Further, the skid 1 and pickup coil 3 are provided in a shield 99 so as to cut ...
Photosynthetic and PSII light responses at a range of leaf temperatures were measured on leaves of apple (Malus domestica Borkh. cv. Red Gala) trees growing in field conditions. The objective was to assess the interaction between photon flux density (PFD) and temperature on these processes. ...
The streamwise mass flux Q is defined as the vertical integral of the streamwise mass flux density q measured at each height z38,39,40,41,42. In this paper with Q we indicate streamwise mass flux and with q we indicate mass flux (see "Materials and methods" section). Q is ...
which can be defined as the ratio between output signal and the measured property. Heat fluxmeters measure the heat flux density (W/m2) and give an output voltage (V), thus the sensitivity unit is Vm2/W. In the ideal scenario, the function is linear and therefore the sensitivity is cons...
Concentration, particle flux and other variables have been measured in an axisymmetric air jet laden with glass spheres of density ρP=2450kg/m3. The jet is discharged through a pipe of about 1 m length ending in a nozzle of diameter D=12 mm, area contraction ratio rAo/Ai=5.14 and length...
