Studies on coupled transfer of soil moisture and heat have been widely carried out for decades. However, little work has been done on red soils, widespread in southern China. The simultaneous transfer of soil moisture and heat depends on soil physical properties and the climate conditions. Red soil is heavy clay and high content of free iron and aluminum oxide. The climate conditions are characterized by the clear four seasons and the serious seasonal drought. The great annual and diurnal air temperature differences result in significant fluctuation in soil temperature in top layer. The closed and evaporating columns experiments with red soil were conducted to simulate the coupled transfer of soil water and heat under the overlaying and opening fields’ conditions, and to analyze the effects of soil temperature gradient on the water transfer and the effects of initial soil water contents on the transfer of soil water and heat. The closed and evaporating columns were designed similarly with about 18 °C temperatures differences between the top and bottom boundary, except of the upper end closed or exposed to the air, respectively. Results showed that in the closed column, water moved towards the cold end driven by temperature gradient, while the transported water decreased with the increasing initial soil water content until the initial soil water content reached to field capacity equivalent, when almost no changes for the soil moisture profile. In the evaporating column, the net transport of soil water was simultaneously driven by evaporation and temperature gradients, and the drier soil was more influenced by temperature gradient than by evapo- ration. In drier soil, it took a longer time for the temperature to reach equilibrium, because of more net amount of transported water.

Simulation models of heat and water transport have not been rigorously tested for the red soils of southern China. Based on the theory of nonisothermal water-heat coupled transfer, a simulation model, programmed in Visual Basic 6.0, was developed to predict the coupled transfer of water and heat in hilly red soil. A series of soil column experiments for soil water and heat transfer, including soil columns with closed and evaporating top ends, were used to test the simulation model. Results showed that in the closed columns, the temporal and spatial distribution of moisture and heat could be very well predicted by the model, while in the evaporating columns, the simulated soil water contents were somewhat different from the observed ones. In the heat flow equation by Taylor and Lary (1964), the effect of soil water evaporation on the heat flow is not involved, which may be the main reason for the differences between simulated and observed results. The predicted temperatures were not in agreement with the observed one with thermal conductivities calculated by de Vries and Wierenga equations, so that it is suggested that Kh, soil heat conductivity, be multiplied by 8.0 for the first 6.5 h and by 1.2 later on. Sensitivity analysis of soil water and heat coefficients showed that the saturated hydraulic conductivity, KS, and the water diffusivity, D(θ), had great effects on soil water transport; the variation of soil porosity led to the difference of soil thermal properties, and accordingly changed temperature redistribution, which would affect water redistribution.

【目的】类黄酮物质是酿酒葡萄的重要代谢产物，对葡萄果实及其葡萄酒的品质有重要影响。研究不同砧木对‘丹娜’（Vitis vinifera L. cv. Tannat）葡萄基本理化指标和类黄酮物质的影响，为砧木的选择利用提供理论依据。【方法】以‘丹娜’葡萄新梢为接穗，绿枝嫁接‘1103P’‘101-14’‘SO4’和‘贝达’（‘Beta’）等4种不同砧木，在分析不同嫁接苗商业采收期（2016、2017和2019年）葡萄果实基本理化指标（可溶性固形物、可滴定酸、pH、百粒重）的基础上，利用高效液相色谱-质谱联用（HPLC-MS）技术，检测‘丹娜’葡萄不同砧穗组合和自根苗的类黄酮物质组成和含量。【结果】砧木对‘丹娜’葡萄果实百粒重影响较小，自根苗和‘101-14’嫁接的‘丹娜’葡萄可溶性固形物较高；Tannat/1103P、Tannat/101-14和Tannat/Beta组合果汁可滴定酸浓度高于自根苗；Tannat/SO4组合的花色苷和黄酮醇含量最低，Tannat/101-14组合与自根苗花色苷和黄酮醇含量较高；Tannat/101-14组合果皮中的黄烷醇含量较高，Tannat/1103P组合果皮中花色苷、黄酮醇含量较低，但黄烷醇含量较高。通过OPLS-DA模型，发现与自根苗相比，Tannat/101-14组合差异化合物主要是二甲花翠素类花色苷；Tannat/Beta组合主要差异化合物为二甲花翠素类、花翠素类和乙酰化类花色苷、槲皮素类黄酮醇以及总黄烷醇；而Tannat/SO4组合与自根苗差异化合物二甲花翠素类、花翠素类、花青素类和乙酰化类花色苷及槲皮素类黄酮醇；Tannat/1103P组合的差异化合物则主要为乙酰化类和二甲花翠素类花色苷、槲皮素类黄酮醇。【结论】在北京地区，4种砧木嫁接都有降低‘丹娜’葡萄果实中甲基花青素类、甲基花翠素类、花青素类、非酰化类、乙酰化类、香豆酰化类花色苷以及梅酮类和西伯利亚落叶松黄酮类黄酮醇物质的趋势。‘101-14’嫁接的‘丹娜’葡萄果皮中花色苷、黄酮醇、黄烷醇等类黄酮物质积累较多，有利于酿酒品质的提升，推荐使用；而‘SO4’嫁接的‘丹娜’葡萄类黄酮物质积累较少，不推荐使用。

The objectives of the present study were to evaluate the yolk-sac and oil globule absorption and point of no return(PNR) of pikeperch(S ander lucioperca L.) larvae. Artificial propagation of pikeperch was performed at(15±2)°C. Yolk-sac absorption, oil globule absorption, larval growth and the first initial feeding rate were observed to analyze the early growth and to determine the PNR of pikeperch larvae. The total length of newly hatched(0 day after hatching, DAH) pikeperch larvae was(4.25±0.22) mm and the volume of the yolk-sac and the oil globule was(0.30±0.12) mm3 and(5.14±2.28) 10-2 mm 3 respectively. The yolk-sac and the oil globule were exhausted at 11 DAH and 14 DAH, respectively. Pikeperch larvae began feeding at 8 DAH with an initial feeding rate about 10.0%. From 9 to 14 DAH, the initial feeding rate increased rapidly, and reached its highest(about 82.7%) at 14 DAH. It declined thereafter, 48.9% at 15 DAH and 35.6% at 16 DAH, thus the pikeperch larvae reached PNR by 15–16 DAH. The appropriate first feeding time for the pikeperch larvae is 11–12 DAH, when the initial feeding rate is higher than half of the maximum initial feeding rate.

综述了阴离子捕获剂的结构、性能、制备与表征方法、吸附专属性及其在环境修复方面的应用。阴离子捕获剂是一种具有层状结构的阴离子粘土,由于其特殊的结构和性能,可通过层间阴离子交换、层状结构重建等机制来吸附环境中的阴离子,从而清除环境中的污染物。大量研究表明,阴离子捕获剂对环境中以络阴离子形式存在的重金属污染物有很强的吸附能力,并能有效吸附水体中的N、P、As、Se和放射性元素。此外,阴离子捕获剂还能吸附有机污染物,如农药、酚类化合物、洗涤剂和腐殖质等。从环境中除去不同类型的有毒有害组分,需使用不同类型的阴离子捕获剂。其吸附能力主要由捕获剂本身的特点和外部理化条件所决定。阴离子捕获剂的研究已成为当前环境保护工程和技术研究的一个新热点。
