Gmt site evaluation at las campanas observatory。
机载LIDAR技术作为一种高精度的三维地物探测手段，其相应的数据格式也在不断发展。美国摄影测量与遥感（ASPRS）协会下的LIDAR委员会于2003年发布了标准LIDAR数据格式LAS，经过改进，目前已有4种版本，分别是LAS 1.0、1.1、1.2与2.0（拟定版）。本文在解析4种版本的基础上，探讨了LAS标准格式的发展趋势，并采用IDL 6.2语言对该格式的LIDAR数据进行读取和转换试验，检...
摘要 选择小鼠腺苷脱氨酶ｍＲＮＡ特异Ｒｉｂｏｚｙｍｅ做为目的Ｒｉｂｏｚｙｍｅ（Ｒｚ），在目的Ｒｉｂｏｚｙｍｅ两侧分别设计５＇－顺式Ｒｚ和３＇－顺式Ｒｚ，在目的Ｒｉｂｏｚｙｍｅ上设计ＢａｍＨＩ酶切位点，并构建了上述Ｒｉｂｏｚｙｍｅ转录载体ｐＳＣＲｚ２６２，采用该质粒进行体外转录，并对转录靶ＲＮＡ分子进行了切割反应。结果显示ｐＳＣＲｚ２６２在转录过程中发生了自身切割，并释放出目的Ｒｉｂｏｚｙｍｅ－Ｒｚ...
可聚硼酸酯表面活性剂的表面化学性质及与LAS相互作用
可聚合表面活性剂 硼酸酯 临界胶束浓度 分子相互作用参数
2010/2/23
用表面张力法研究了可聚合硼酸酯表面活性剂(BES)水溶液不同温度下(288-313 K)的表面活性和热力学函数变化；考察了BES与十二烷基苯磺酸钠(LAS)在0.5 mol·L-1 NaCl溶液中的相互作用. 结果表明, 298 K时, BES临界胶束浓度cmc达到0.066 mmol·L-1, γcmc为29.2 mN·m-1；在所考察的温度范围内BES胶束形成自由能(ΔG0m)在-22.4 -...
