信号联接
6)  received signals
接收信号
1.
Monte Carlo method is a classical method used to simulate the mutiplescattering lidar received signals, but its main disadvantage is that calculation time can become prohibitively long.
MonteCarlo方法模拟多次散射激光雷达接收信号是一种经典方法,但这种方法的最大缺点是计算时间很长。
2.
A simple proportional relationship is established between the higher scattering and the single scattering by analyzing each level scattering of the multiple backscattering lidar received signals.
通过对多次后向散射激光雷达接收信号的各级散射的分析,在高次散射接收信号与单次散射接收信号之间建立了一个简单的比例关系,即它们的比值与总衰减系数成比例;用蒙特卡罗方法对激光雷达接收信号进行了模拟。
补充资料:基因剪接
分子式:
CAS号:

性质:  基因工程中的一个重要工序,即将一个DNA分子中的目的基因剪切下来,插入到另一个受体DNA分子中,组成新的重组DNA分子的过程。具体操作是:用限制性内切酶去切割某—DNA分子,取下目的基因;用上述同一种限制性内切酶去处理受体DNA(噬菌体DNA或质粒DNA)分子;然后将目的基因片段与具有切口的受体DNA进行保温,由于它们的末端都含有互补的核苷酸顺序,黏性末端之间可发生“退火”,两条DNA链相邻核苷酸间所缺失的磷酸二酯键,可由特异性的DNA连接酶进行共价连接,形成一个新组装的完整DNA分子。
