Effects of Different Diets on the Dietary Attractability and Selectivity of Chinese Shrimp, Fenneropenaeus chinensis

Attractabilities of different diets and dietary selectivity of Chinese shrimp, Fenneropenaeus chinensis were studied through behavior observation and feeding experiment, respectively. The five diets used in the experiment are: Fish Flesh (FF), Shrimp Flesh (SF), Clam Foot (CF), Polychaete Worm (PW), and Formulated Diet (FD). No significant differences of attractability exist between any two different diets when every two natural diets or all five diets are provided simultaneously. On the other hand, significant differences of attractability exist between FD and every single natural diet when they are provided simultaneously. Results of behavioral observation indicate that natural diets are more attractive than FD. In feeding experiment, Chinese shrimp has distinct selectivity on different diets. It positively selects CF and PW, negatively selects FF and SF, and excludes FD absolutely. The results of the present studies indicate that the dietary selectivity of shrimp was based not only on the attractabilities of the diets, but also on the responses such as growth and food conversion.     

正确认识石蜡油

石蜡油又称矿物油，是从原油分馏所得到的无色无味的混合物。它可以分成轻质矿物油及一般矿物油两种，但轻质矿物油的比重及黏稠度较低。由于矿物油具有低致敏性及良好的封闭性，有阻隔水分蒸发的作用，所以常在婴儿油、乳液或乳霜等护肤品中被当做顺滑保湿剂来使用。因为它具有良好的油溶性质，所以也会出现在卸妆油或卸妆乳中。此外，石蜡乳液系列产品可广泛应用于纺织、造纸等工业助剂，在人造纤维板工业中，可完全替代石蜡作为防水、防潮助剂，比使用石蜡更加简便，成本更低、效果更好。且其具有抗酸、抗碱、耐硬水、水溶性强、乳液稳定，     

鄂尔多斯盆地西峰地区长8砂岩微观非均质性的实验分析

通过真实砂岩微观模型实验,客观地分析了鄂尔多斯盆地西峰地区长8砂岩的微观非均质性特征,发现该区长8储层为致密型砂岩,直观地显示出长8砂岩储层具有很强的微观非均质性,砂岩的成岩作用和孔隙结构是影响鄂尔多斯盆地西峰地区长8砂岩储层微观非均质性的主要原因。在低渗透砂岩中,引起砂岩产生强烈的非均质性,而这些砂岩则形成长8砂岩储层的高渗带。
