Based on stochastic optimization strategy, a formulation methodology is proposed for synthesizing distillation column sequences, allowing more than one middle component as the distributing components between a pair of key components in the non-sharp split.
These researchers observed a narrow CO band (middle component) in mixtures dominated by nonpolar molecules and a broader reddish one in mixtures dominated by polar ices (essentially H2O).
Historically, observations of the stretching mode of CO ice along many lines of sight have revealed decomposition into a broader red-shifted component situated somewhere in the region 2130 2138 cm-1 (red component) and a narrow component centred on 2140 cm-1 (middle component) (Lacy et al., 1884; Whittet et al., 1985; Geballe, 1986).
The differences of the activation energy also indicate the energy differences of the lower two states, and the obtained value is 55 meV between the slowest component (τ1) and the middle component (τ2), which agrees with the results obtained from the global fitting method.
Then, according to the literature [23], the middle component is associated with O2− ions in the O deficient regions within the ZnO lattice, and the intensity of this component may be partially connected with the concentration of VO, which has the lowest formation energy among the donor-like defects [24].
Laboratory measurements on CO mixtures with other gases deposited on a flat substrate at low temperature have shown that the middle component occurs in mixtures dominated by non-polar molecules (CO2, O2, N2) and that a broader reddish component appears in mixtures dominated by polar molecules, such as H2O, NH3 and CH3OH (Tielens et al., 1991; Palumbo et al., 1995; Ehrenfreund et al., 1996, 1997).
However, the highly saline carbonate environment and bacterial and algal activities elevated the levels of even-chain n-alkanes in the sediments, leading to an obvious even-over-odd predominance of short and middle components C15-C266).
Average amplitudes of the meridional (top) and zonal (middle) components, and number of data (bottom) in each mesh grid are shown.

There has been, however, some concentration of its proximal and distal muscle components and reduction in mass and efficiency of its middle components.
