弹性波法在水库坝基检测中的应用

许多水库大坝，特别是土、石坝，由于长年自然因素和人为破坏，普遍存在渗漏现象。为了维护水库的正常使用，对水库大坝的隐患进行检测，显得尤其重要。采用弹性波法中的垂直反射波法和瞬态面波法，利用坝基缺陷可能造成的反射波场和速度变化特征，给出了综合检测水库土、石坝基缺陷情况的方法技术。通过实践，验证了采用综合方法技术进行检测的有效性和实用性。     

Comparison of Taste Components between Triploid and Diploid Oyster

The main taste components of triploid and diploid oyster (Crassostrea gigas) were compared. Free amino acids, inosine monophosphate, succinate, trimethylamine oxide and betaine in fresh and boiled extractives were analyzed. The protein, lipids, glycogen, moisture and ash, which may affect the flavour, were evaluated. In boiled extractives, the amino acids were 394.1 mg(100g)^-1 in diploid and 183.5 mg(100g)^-1 in triploid. However, in fresh oyster extractives, they were 320.0 mg(100g)^-1 and 147.3 mg(100g)^-1 respectively. The inosine monophosphate in triploid was 44% more than that in diploid, and a little difference existed in the content of trimethylamine oxide between them. The contents of these taste components were the basis for taste flavour pattern determination.     

对按孔段综合递减系数制定钻探预算定额的思考

在地勘行业,钻探预算定额模式大多是采用按不同孔深不同孔段以一个综合递减系数来制定。此种方法,固然有其理论依据及合理性。然而,笔者在实际工作中,通过大量的钻探勘探统计资料发现:台月效率的高低是与一定的孔深有关系,并随着钻孔的加深而下降,但并非呈直线匀速下降;孔     

Mantle processes during ocean formation：Petrologic records in peridotites from the Alpine－Apennine ophiolites

Mantle peridotites were early exposed at the sea-floor of the Jurassic Tethys derived from the subcontinental mantle of the Europe-Adria system. During continental rifting and oceanic spreading, these lithospheric peri-dotites were percolated via diffuse reactive porous flowby melt fractions produced by near-fractional melting of the upwelling asthenosphere. Ascending melts inter-acted with the lower lithosphere, dissolving pyroxenes and precipitating olivine, and crystallized at shallower levels in the mantle column causing melt impregnation.Subsequent focused porous flow formed replacive dunitechannels, cutting the impregnated oeridotites, which were conduits for upward migration of MORB-type liq-uids. Melt migration produced depletionlrefertilization and significant heating of the percolatedlimpregnated mantle, i.e the thermochemical erosion of the litho-sphere. Impregnated and thermally modified lithos-pheric mantle was cooled by conductive heat loss dur-ing progressive lithosphere thinning and was intrudeaby MORB magmas, which formed Mg-rich and Fe-richgabbroic dykes and bodies. Alpine-Apennine ophiolitic peridotites record the deep-seated migration of melts which changed their compositions and dynamics during the rift evolution. The thermochemical erosion of the lithospheric mantle by the ascending asthenospheric melts, which induces significant compositional and rhe-ological changes in the lower lithosphere, is a major process in the evolution of the continent-ocean transi-tion towards a slow spreading oceanic system.

试论高校负债发展中的筹资风险及其控制策略

高校发展中的适度负债是解决制约高校超常规发展的有效方式，但高校在使用负债资金实现办学目标时，却存在巨大的风险。控制负债筹资风险的策略是：1．把握现实，转变观念，树立风险意识；2．确定适度的负债结构，降低资金成本；3．正确把握负债的数量与规模，保持合理的负债比率，提高偿债能力；4．强化预算管理，建立控制风险和抵御风险的内部机制。
