造模后，中枢5-HT呈现降低趋势，这可能是导致动物出现活动能力下降和兴趣缺失的原因之一，蜘蛛香环烯醚萜可以增加下丘脑、海马和杏仁核中5-HT含量，推断蜘蛛香环烯醚萜可通过干预中枢的5-HT通路来改善IBS精神症状。3.2蜘蛛香环烯醚萜对胃肠激素的影响目的：探讨蜘蛛香环烯醚萜对慢性应激所致IBS大鼠SP和VIP的影响方法：动物随机分为对照组、模型组、昂丹司琼组、氟西汀组、蜘蛛香环烯醚萜24.92mg/kg、12.46mg/kg、6.23mg/kg组。

The performance of the selected coating systems was experimentally verified,while some of the selected costing systems were brought into engineering practice.As the results,it was suggested to use a coating system composed of zinc-rich epoxy primer,micaceous ferric oxide epoxy intermediate,and modifie...

结果显示，对完全浸泡的设备，采用环氧富锌底漆+环氧云铁中间漆+改性环氧面漆的涂层体系有很好的防护效果；对干湿交替的设备采用环氧富锌底漆+环氧云铁中间漆+丙烯酸聚氨酯面漆的防护体系具有良好的防护性能，预计其防护寿命可达到8a以上。

The scale inhibition mechanism of PESA was proposed on the basis of characterization of transformation of calcium carbonate crystal by means of X-ray Diffraction and scanning electron microscopy. The effect of temperature on corrosion inhibition efficiency of PESA was investigated and the Bockris substitution model is proposed to study the thermodynamics of inhibiting process of PESA. The calculation results show the adsorption of PESA on carbon steel is a spontaneous exothermic process with the increase of entropy.
