However neural network with natural parallel structure shows huge advantage in the field of automatic control with high real - time . consequently it promotes the more development of inverse control in the design of control system and regulator 而神经网络本质的并行结构在处理实时性要求高的自动控制领域中所显示出的极大的优越性使得逆控制在控制系统和调节器的设计中得到进一步发展。
This paper introduces the compilation of multi - level network plan , discusses the problems of overlap relation and technical disposal of sub - networks , puts forward the optimization principle and method 摘要多级网络计划系统可用于大型复杂建设工程进度计划的编制与控制，对于动态管理复杂项目具有科学性和实用性，在项目管理中能快速地处理层次复杂、作业数较多、动态调整要求高的项目计划。
Because the function of real time largely depends on good hardware and system software , the present author and his partners apply the qnx operation system which is a highly reliable and rapidly responsive real - time operation system to the mdsl system 实时性与计算机的硬件、系统软件有很大关系，因此在实时性要求高的系统中，应首选可靠性高、响应快的实时操作系统为计算机的操作系统。
Experience formula is applicable for some small and low precision - requested assembly fixture , for some complicated and large scale ones , fem for space frame is requested . at the end , an example based on this system has been given 即对于结构简单、精度要求不高的部装型架，采用材料力学和结构力学理论公式进行刚度校核；对于总装等结构复杂，精度要求高的大型型架，采用空间刚架的有限元分析。
Discharge declaration and registration have large data size , strong logicality , high professional requirements as the characteristics , so environmental protection departments must strive to strengthen the audit to obtain integrated and accurate data reporting 摘要排污申报登记工作具有数据量大、逻辑性强、专业要求高的特点，环保部门必须力求通过强化数据的审核来获得完整、准确的排污申报数据。
Compared with msjpda , amsjpda demands less time and has similar correct association rate . all suggest that amsjpda is suitable for the real - time fusion system in complex environment in clutter . attribute - track correlation is also an important part in data fusion system 近似联合概率法解决了在实际工程中目标批次增加时关联正确率和时间消耗间的矛盾，适用于大容量且实时性要求高的融合系统。
People often use the process of clay sand to produce varieties of casting which are required standard figure , precise dimensions , smooth surface and high productivity in some industry for example vehicle , tractor , internal combustion engine 在汽车、拖拉机、内燃机等行业中凡是对外形规范化、尺寸精度、表面光洁度要求高的生产量大的各类铸件，采用粘土砂的生产工艺是目前国内外公认的主要手段之一。
