查询词典 band

This study demonstrates optically and spatially band-tunable color cone lasers based on DDCLC cells with a photoisomerizable chiral dopant. The band-tunability is attributable to the recovery of the helix of the CLC resulted from the trans-cis isomerization induced decrease of the helical twisting power of the chiral dopant.The more the chiral cis-isomers are produced, the larger the tuned lasing band is.

本文主要藉由在胆固醇液晶射中加入可光致同素构化亲手性材，使胆固醇液晶所输出的彩色锥角射波段可光调控及空间调控，其射输出波段可调控的机制是由於当同素构化反应产生后，光致同素构化亲手性材的HTP值低并造成胆固醇液晶距改变，藉此间接调控输出的射波长，同素构化的程愈高，胆固醇液晶所输出的彩色锥角射波段可调控范围也愈大。

There are three parts included. The first part is the prepositive-amplifier, it gets broadband high gain and flat frequency response. The second part is the U band quadrupler, which composed of two doublers using a PHEMT chip HMMC-5040, a Schottky diode of DMK-2790, a HMMC-5040 amplifier, and a fin-line transitional stage.

The results indicated that four SOD bands were identified in five tissues, and the band with the biggest mobility ratio were found weakly in gill, digestive gland and adductor muscle but not in foot and mantle. Two ATPase bands were found in four tissues except digestive gland. One MDH band was found in five tissues, but the MDH gene expressed strongly in foot and adductor muscle. Two ME bands were examined in foot, adductor muscle and mantle, but the band with smaller mobility ratio was found in gill and digestive gland.
