济南市破损山体恢复治理的调查研究

自然生态破坏是我国当前环境质量恶化的重要原因之一,已成为我国经济、社会可持续发展的严重障碍。20世纪90年代以来,随着国家对石质资源需求的迅速增长以及该行业经济的迅猛发展,山体开采而造成的生态环境破坏问题也日趋严重,不但影响自然景观、造成污染环境,而且还会诱发山体滑坡,造成水土流失等地质灾害。该项调查研究是以济南市高新区大山坡破损山体为对象,制定相应的治理措施。

Modelling wheat breakage during roller milling using the Double Normalised Kumaraswamy Breakage Function: Effects of kernel shape and hardness

The effects of wheat properties on breakage during First Break roller milling, as described by the Double Normalised Kumaraswamy Breakage Function (DNKBF), were investigated. A set of 45 wheats from nine varieties representing the range of commercial varieties grown in the UK, and grown over three harvest years at several nitrogen fertiliser levels, were milled at five roll gaps under Sharp-to-Sharp and Dull-to-Dull dispositions. The resulting particle size distributions were fitted with a DNKBF in order to understand the physical significance of the DNKBF parameters and to relate them to shape and hardness. The DNKBF parameters related strongly to hardness as measured using either the Single Kernel Characterisation System or Particle Size Index, allowing the particle size distribution over the range 0–4000 μm to be predicted solely from wheat hardness. A residual analysis showed that the remaining variation was correlated with kernel mass, and that more elongated kernels break to give slightly larger particles than more spherical kernels of equivalent hardness. Two types of breakage are identified, one of which principally produces many small endosperm particles along with large bran particles, while the other tends to produce mid-sized particles. The former dominates under Dull-to-Dull milling and for soft wheats, while the latter becomes more prominent under Sharp-to-Sharp milling and for harder wheats.     

Interpreting Crush Response Profiles from the Single Kernel Characterization System

Modern versions of the Single Kernel Characterization System allow force profiles recorded for individual kernels during crushing to be retrieved. The current understanding of the meaning of the averaged Crush Response Profile (aCRP) is challenged in the current work. When bran layers are removed, the features of the aCRP that have been interpreted as the bran layers' elastic response and subsequent collapse are retained. By contrast, when the crease is removed, these features are largely eliminated. The crease depth correlates with the first peak force, providing further evidence that wheat kernels tend initially to break across the crease. The initial slope of the force-deformation curve depends on the inherent strength of the endosperm material opposite the crease, while the magnitude of the initial peak force depends on the strength and thickness of this material, and hence on the crease depth. It is concluded that through the averaging process, aCRPs give a misleading picture of wheat kernel breakage in the SKCS. The Hardness Index currently reported by the SKCS, which is based on identifying breakage events as indicated by the jaggedness of the force profile, would appear to give a more fundamentally sound basis for quantifying wheat properties relevant to breakage.
