A novel algorithm which is based on space contraction for solving MINLP problems is proposed.
提出了一种基于空间收缩的求解MINLP问题的新算法。
We mainly apply the contraction principle in analysis and properties of some Spaces. By the computable functions constructed, we extend the solution from the internal to the entire space.
证明过程中主要应用了分析中的压缩映象原理和一些空间的性质，通过构造可计算函数，来把解从一个区间延拓到整个空间。
Therefore, the Contraction mapping principle in semi-metric space has been proved.
进而证明了半度量空间中的压缩映像原理。
Oil temperature drop and oil contraction can cause gas space growing in oil pipe and line packing during hot oil pipeline shutdown and restarting.
热油管道停输后，管内油品降温收缩，管内会产生油蒸气空间，从而使管道再启动时出现启动充装过程。
It can be effectively separate the noise and vibration as its have some space at the end of the tube, the pipeline is not affected when thermal expansion or contraction.
因管末端有间隙可有效地隔断噪音及振动地传播，热胀冷缩时管路亦不受影响；
To be supportive, put metal straps on both long and short sides and reserve space for expansion and contraction.
长边、短边请加金属压条，并预留膨胀空隙，加强固定力量。
