Numerical analysis of the transport and restoration schemes of aqueous oil in soils

 On the basis of field investigations and tests, the authors developed a coupling model of water and solute movement to quantitatively analyse the effects of climate condition, irrigation mode, chemical reactions and restoration schemes on aqueous oil (effective oil) distribution using the finite difference method. It is concluded from this study that the effect of strong adsorptive forces between aqueous oil and the soil matrix is the distribution of aqueous oil in the plough layer rather than its migration to groundwater. In addition, restoration schemes involving clean-wastewater mixing irrigation and crop-type adjustment may greatly reduce the aqueous oil concentrations, but clean surface water or groundwater irrigation must be used for complete restoration of the contaminated soils.

海气耦合系统中的季节内振荡模态

从海气相互作用的观点出发研究了热带大气季节内振荡产生的一种可能原因,发现在不考虑大气内部大尺度凝结反馈过程的条件下,线性简单海气耦合系统在真实的参数取值范围内存在一类和实际观测类似的季节内振荡模态,这种模态可以不稳定缓慢东传或西传或表现为驻波,海洋边界波反射效应对这种振荡模态的形成无根本性影响。这一结果为解释洋面上观测到的热带大气低频振荡的局地特征提供了理论背景。

Concepts of blast hole pressure applied to blast design

Blast hole pressure is the starting point for many blast design calculations, but the way in which it is usually derived, from measured detonation velocity, indicates that more thought is needed as to its true meaning and implication. The general impression is given that the energy in the hole is defined by velocity of detonation (VoD), but this is rarely the case. VoD is defined by the energy released in the detonation driving zone between the shock front and the sonic (or CJ) surface, and for commercial explosives it is normal for reaction not to be complete within this zone. Reaction and energy delivery continues behind it, not reflected by VoD. Thus it would be more appropriate to use the theoretical VoD, not the measured VoD, to derive the starting pressure, since this would reflect the energy input of full reaction. In decoupled situations, the derivation of pressure at the blast hole wall using a polynomial decay concept is also of debatable value, and an alternative is offered.     

Spectral analysis of planetary waves seen in ionospheric total electron content (TEC): First results using GPS differential TEC and stratospheric reanalyses

The coupling of the neutral atmosphere and the ionosphere through planetary waves (PW) (zonal wavenumber 0–5) is investigated by spherical harmonic analyses of the ionospheric total electron content (TEC). These analyses detect mean variations, standing and travelling waves which are assumed to be signatures of PW. Database used for TEC analyses are 3 years of hourly TEC maps covering the higher middle and polar latitudes. They are regularly produced by DLR Neustrelitz. The obtained results are compared with PW analyses using NCEP/NCAR and Met Office stratospheric reanalyses. Case studies show that signatures of PW occur simultaneously in the middle atmosphere and ionosphere.
