Effect of coating thickness on the calibration and measurement uncertainty of a wide-band liquid crystal thermography

<正>The liquid crystal thermography is a high-resolution and non-intrusive optical technique for full-field temperature measurement.We present detailed calibration data for a wide-bandwidth thermochromic liquid crystal(TLC) to investigate the effect of the coating thickness on the hue-temperature characteristics and the measurement uncertainty of the TLC.It is found that the coating thickness has appreciable effect on the TLC hue-temperature curve.For TLC coatings with the thickness over 20μm,a thicker TLC coating shows a relatively smaller measurement uncertainty,but the effect of the coating thickness is non-distinctive on the measurement uncertainty.     

THE DIVERGENCE OF LAGRANGE INTERPOLATION FOR |x|α (2＜α＜4) AT EQUIDISTANT NODES

It is a classical result of Bernstein that the sequence of Lagrange interpolation polynomials to |x| at equally spaced nodes in [-1, 1] diverges everywhere, except at zero and the end-points. In the present paper, we prove that the sequence of Lagrange interpolation polynomials corresponding to |x|α(2 ＜α＜ 4) on equidistant nodes in [-1,1] diverges everywhere, except at zero and the end-points.

CZE Determination of Calixarenes and Related Derivatives Using Acetonitrile as a Modifier

The applications of third-generation host compound calixarenes have been restricted due to their high price and shortage of supply. To obtain high pure calixarenes with high yield, synthesis strategy and analytical method investigations are necessary. The present work describes capillary zone electrophoresis (CZE) for the separation and determination of calixarene derivatives under the optimized CZE conditions within 20 min. The CZE method was evaluated with linear ranges, detection limits, recoveries and repeatability. The results indicated that the method was accurate and reproducible. As expected, it could be utilized to separate and evaluate calixarene derivatives during their synthesis and purification.
