higher pair
7.I was 11 when I first fell in love with a pair of shoes: fluorescent green Pumas with jump-higher engineering and matching laces. Shoes have enriched my life ever since.
8.The operation is steady for the system at higher heating temperatures and wide operation conditions, and the coefficient of performance (COP) may retain constantly above 0.95. The COP is a little lower than that of the system only with water-lithium bromide as working pair at the similar conditions, but the corresponding chilling temperatures may be 1℃ and -5℃ respectively.
10.The focusing curves ( r z ), which higher order mode laser beams(i.e.: the mode TEM 11 、TEM 12 (or TEM 21 )、TEM 22 of Hermitian Gauss beams and the mode TEM 10 、TEM 11 of Laguerre Gauss beams) propagate through a focusing optical system (for example: a pair of lens focusing system), are obtainable on the basis of Huygens Fresnel principle and Sampling theory and by programming , calculating, and making use of Graftool.
