Polymerization and Mixing Restrictions on the Production of Freon 对氟里昂限制问题的动向
The strong consistency of the improved kernel regression function estimate with ρ-mixing dependent samples is obtained under some conditions. And the restrictions on the mixing speed of ρ-mixing dependent samples is less than that of α-mixing, φ-mixing dependent samples. 在一定条件下得到了样本平稳ρmixing下非参数回归函数改良核估计的强相合性,所得结果对混合速度的要求要比样αmixing,φmixing本相依下对混合速度的要求来得弱。
According to the theory of sampling, mixing phenomena are, unfortunately, inevitably caused by Moire fringe and false-color, due to the restrictions on the solid imaging sensor pixel size in the digital imaging system. 由于数字成像系统中固体成像传感器的象素大小有一定限制,根据采样理论,混频现象导致的莫尔条纹和伪彩色不可避免。
This paper introduces current technologies of heavy oil mixing with water. However, each technology has advantages and disadvantages, and certain restrictions would exist in practice. 本文介绍了目前常用的重油掺水方法,由于每种方法都存在一些优缺点,故在实践中都有一定限制。
