transmittance 

A measure of transmission expressed as the ratio of the intensity of the transmitted light I′ to the intensity of the incident light I, for a specified wavelength, i.e. T = I′/I. It is usually given as a percentage, i.e. T = I′/I ✕ 100. Syn. total transmittance. See absorbance; optical density.

As discussed above, the PANNFs/PU films, prepared with PAN concentration of 12 wt%, heating temperature of 200[degrees]C and heating time of 10 min, showed 95% light transmittance as shown in Fig.
In this proposed antenna design, the square ring FSS structure is used to replace the metal ground of the microstrip antenna, so that the ground of the antenna can reflect the electromagnetic waves in the antenna operating frequency band and has good light transmittance at the same time.
The thickness match of ZAZ corresponding to the maximum [[PHI].sub.TC] is 35 nm/9 nm/35 nm with a light transmittance of 85.55% at 550 nm and a sheet resistance of 3.84 [OMEGA]/sq.
Light transmittance of the coating, CDR containing dye-adsorbed silica, before and after being heated at 280[degrees]C for 1 h was measured, and the spectra are shown in Fig.
Aggregation was expressed as the maximum percent change in light transmittance from baseline, with platelet-poor plasma as a reference.
It accounts for three key parameters affecting the energy performance of all building envelopes - i) thermal performance (assembly U-value and thermal mass of opaque construction, glazing properties, internal and external heat transfer coefficients, etc.), ii) daylighting performance (visible light transmittance) and iii) infiltration.
When the sheer shades are lowered, light transmittance is reduced by 30 percent, creating an enhanced experience for all those in attendance and providing the appropriate light for HD videography.
Shiratori and colleagues (28) synthesized ultra-water-repellent films by the LBL assembly of polyelectrolytes and Si[0.sub.2] nano-particles, but they did not represent any data concerning the light transmittance of the films.
The inputs including the absorption coefficient ([[mu].sub.a]), the scattering coefficient ([[mu].sub.s]) and the anisotropy coefficient (g) of the thermotropic material, using the inverse adding-doubling (IAD) method for the simulation of the angle-dependent light transmittance of thermotropic material at different temperatures at the wavelength range of 350-1800 nm, have been determined in Figures 2, 3, and 4.
By reducing one glass substrate, OGS touch panels are lighter, thinner, with higher light transmittance. Such panels cost about 20% less than traditional counterparts; while major rivals as in-cell technology and thin-film type face problems of low yield rate and lower efficiency.
90 kg (198 lb) for PC, and the PET bottle's light transmittance decreases only 6% after 10 washing cycles, vs.
Specific topics include the synthesis and metabolism of melatonin in the skin and retinal pigment epithelium, melatonin's effect on reproduction, melatonin in dentistry, using melatonin in anesthesia and surgery, controlling gastric secretion and preventing gastric mucosal lesions, decreased light transmittance because of aging and melatonin, melatonin and melanoma, and the melatonin modulation of vascular structure and function.
