- Comparing with the model test data the result of the calculation is more close to that from the formula in " design and calculation standard for submarine structure ( gjb ) "
与实验数据进行比较，其计算结果比利用gjb 《潜艇结构设计计算规则》的计算结果更接近于真实值。 - The test quantum is generally small due to the extremely complexity of modern weapon systems , high expenses and long cycle of the tests , which makes the demonstration methods of gjb more difficult to be put into practice
由于现代武器装备系统复杂，试验费用昂贵，且试验周期长，因而现场试验的次数往往比较少，而国军标中的方法需要较多的试验样本量，使其在实际工程中难以应用。 - Then , according to the requirement analysis , concept design , logic design and database design , the electronic instrument failure rate database was designed and the components failure rates and n factors in gjb / z299b - 98 were established in the database
其次，按照开发关系型数据库所要求的需求分析、概念设计、逻辑设计和物理设计四个阶段，设计了电子设备失效率数据库并做了数据录库工作。 - The constitutions and principles of position of gps > glonass and beidou navigation system are described all around in this article , and the following technologies are studied and realized : communication between com ports with oop technology , compound navigation with gps and glonass . calculate velocity , pseudorange difference , smoothing pseudorange with the carrier - phase and models to correct error are also done ; the transforms between wgs - 84 and pz - 90 , as well as wgs - 84 and beijing54 coordinate system ; the technologies to display and manage bitmap , vector map based on mapx also ; conversion of data formats between gjb and mif data format of maplnfo corp . arithmetic of creation dem data based on contour line data from 1 - . 25000 map data with gjb format . texture the surface of terrains with corrected aviation image
