General Construction of the Basic Database System of the Geography Information GIS dB3

地学信息基础数据库系统&GIS-dB3的基本结构

You can either restore to Backup DB3 or earlier .

您可以将它恢复到BackupDB4或更早备份。

Imagine , if Backup DB3 isn 't taken , you have no choice but to get earlier than backup that was taken at2004062510 .

想像一下，如果没有BackupDB4这个备份映像，除了获取一个比2004062510时所作的备份映像更早的备份映像以外，您将别无选择。

Error signals are decomposed and reconstructed by db3 wavelet . reconstructed normal variation is less than angular measuring system precision , reconstructed signals are used to compensate the system errors instead of original error signals .

采用db3小波对测角系统误差信号进行分解与重构，重构标准差小于测角系统精度，重构信号满足精度要求，可以用重构信号代替原误差信号进行计算机误差补偿。

The protein spot DB3 showed some similarity with ODR-3 . It belonged to the a subunit of G protein . This protein might combine with receptor and activate some signal transduction pathway , then induce some defensive responses of cotton .

蛋白质点DB3与ODR&3蛋白具有同源性，此蛋白为G蛋白的α亚基，在与受体结合后可激活一定的信号传导途径，从而诱导棉花的一些防御反应。
