通过构建水产饲料卤虫卵孵化恒定磁场处理装置,研究卤虫卵孵化过程中溶解氧含量、pH值和孵化率的变化规律。结果表明:恒定磁场提高了卤虫卵的孵化率,恒定磁场强度与卤虫卵孵化率呈正比,最高孵化率达97.2%。孵化过程中溶解氧含量呈单凹型曲线,添加恒定磁场后使孵化液中溶解氧含量增加。随着孵化时间增加,pH值不断下降,恒定磁场对孵化过程中pH值变化没有明显影响。添加恒定磁场后使溶解氧含量增加可能是卤虫卵孵化率提高的关键因素之一。

二十二碳六烯酸(Docose Hexaenoie Acid,DHA)具有提高记忆与思维能力、改善视力等生理作用,但其不饱和度高,易腐败,稳定度差,目前多数采用喷雾干燥将其微胶囊化。但要获得高质量DHA藻油微胶囊,需要首先制备高稳定度、高包埋率的DHA乳状液。为此,需要优化高稳定度DHA藻油乳状液的制备条件,试验结果表明,最佳复合壁材为大豆分离蛋白加麦芽糊精;最佳乳化剂为蔗糖脂肪酸酯加单硬脂酸甘油酯(质量配比为7∶3),最佳乳化剂添加量为2.0%,最佳剪切乳化时间为7 min,最佳乳化温度为85℃。在此条件下乳化液稳定度保持在95.6%以上。

Deep oil and gas reservoirs are under high-temperature conditions, but traditional coring methods do not consider temperature-preserved measures and ignore the influence of temperature on rock porosity and permeability, resulting in distorted resource assessments. The development of in situ temperaturepreserved coring(ITP-Coring) technology for deep reservoir rock is urgent, and thermal insulation materials are key. Therefore, hollow glass microsphere/epoxy resin thermal insulation materials(HGM/EP materials) were proposed as thermal insulation materials. The materials properties under coupled hightemperature and high-pressure(HTHP) conditions were tested. The results indicated that high pressures led to HGM destruction and that the materials water absorption significantly increased; additionally,increasing temperature accelerated the process. High temperatures directly caused the thermal conductivity of the materials to increase; additionally, the thermal conduction and convection of water caused by high pressures led to an exponential increase in the thermal conductivity. High temperatures weakened the matrix, and high pressures destroyed the HGM, which resulted in a decrease in the tensile mechanical properties of the materials. The materials entered the high elastic state at 150.C, and the mechanical properties were weakened more obviously, while the pressure led to a significant effect when the water absorption was above 10%. Meanwhile, the tensile strength/strain were 13.62 MPa/1.3%and 6.09 MPa/0.86% at 100.C and 100 MPa, respectively, which meet the application requirements of the self-designed coring device. Finally, K46-f40 and K46-f50 HGM/EP materials were proven to be suitable for ITP-Coring under coupled conditions below 100.C and 100 MPa. To further improve the materials properties, the interface layer and EP matrix should be optimized. The results can provide references for the optimization and engineering application of materials and thus technical su

以4,4＇-二溴联苯（4,4-＇DBB）为代表性有机物,对比研究了单独O3和O3/H2O2处理持久性有机污染物的效能,并通过UV254值表征溶液的TOC、DOC值.结果发现,2种方法都可以达到一定的去除效果,尤其是碱性条件下H2O2的加入使去除率得到进一步提高.4 mg/l的4,4-＇DBB溶液反应270 min后,最终去除率达到78.0%,UV254值变化率与去除率基本吻合,最终在76.9%-77.8%之间,矿化程度明显.高低2种浓度比较发现,加相同氧化剂的量,反应相同时间,去除率随溶液初始浓度增高而降低,但浓度越高的溶液的绝对处理量越大.4,4-＇DBB的反应符合动力学拟一级反应规律,计算增强因子f为1.54.
