大口径长输管道用弯管的设计制造

在国内外缺少适用于大口径长输管道用的大曲率半径的弯管设计、制造规范的情况下，建议在符合现有规范的条件下设计时，应考虑曲率半径的选取尽可能小，以减小所需变制设备、芯模的规格尺寸和空间场地；当弯管和与之相连的直管材质不同时，应在壁厚计算公式中乘以两种不同材质的屈服强度比值；为节省投资和合理利用钢材，应慎重确定弯管制造的壁厚减薄量；为保证弯头质量，在选材上不宜选用螺旋焊缝钢管，而应选用高强度低合金钢管或

Physiological responses of transported goats treated with ascorbic acid during the hot-dry season

The aim of the present study was to determine the physiological responses of transported Red Sokoto goats (RSG) treated with ascorbic acid (AA). Ten RSG treated orally with ascorbic acid served as experimental subjects, while seven goats treated with sterile water served as the control. The goats were transported for 8 h. The ambient temperature and relative humidity during the study period fluctuated between 21 and 38°C and 51 and 91%, respectively, which indicated that the season was thermally stressful and did not favor transportation of goats. The rectal temperature obtained in the control goats was significantly higher (P < 0.01) than the value in the experimental goats after transportation. There was a significant decrease (P < 0.05) in eosinophil counts and an increase (P < 0.01) in neutrophil counts and neutrophil : lymphocyte ratio recorded in the control goats after transportation, which suggested that the control goats were physically and emotionally stressed. The control goats lost 11.9% of their initial liveweight, while the experimental goats lost only 1.04% after transportation. Multiple stresses, including extreme meteorological factors, acted upon the transported goats and impaired their homeostatic mechanism. In conclusion, AA administration in goats reduced the adverse effects of road transportation stress.     

Excitability scores of goats administered ascorbic acid and transported during hot-dry conditions

In this study, we investigated the effect of ascorbic acid (AA) administration on goat excitability due to transportation. Ten goats administered AA (p.o.) at 100 mg/kg of body weight before transportation served as the experimental group, and seven goats administered only 10ml/kg of sterile water (p.o.) served as controls. Excitability scores were recorded for each goat; when weighed, before, immediately after, and 3 h after 8 h of transportation. A score of one to four was allocated to each goat; higher scores represent greater excitability. Immediately after transportation, excitability scores decreased significantly, especially those of control goats (p < 0.001). At 3 h post-transportation, the excitability scores of animals in the experimental group were not significantly (p>0.05) different from their pre-transportation normal values, whereas those of control goats were significantly lower (p < 0.01). The correlation i.e. the relationship between excitability score values and percent excitability (percentage of goat with particular excitability score) for different excitability score group 3 h post-transportation was positive and highly significant (p < 0.001), in both experimental and control goats. Our results indicate that road transportation induces considerable stress (depression) in goats as evidenced by a lower excitability score post-transportation. Moreover, the administration of AA pre-transportation facilitated the transition from a state of depression to excitation. In conclusion, AA administration to animals prior to transportation may ameliorate the depression often encountered after road transportation.

管道工程环境与力学行为

长输管道所处的环境比较复杂，主要包括所输送介质的环境，运行操作环境、管道周边环境、沿线自然环境与灾害环境以及管道的施工制造环境。在这些环境的作用下，管道将产生相应的力学行为，主要有承载行为，变形行为，断裂行为，疲劳行为和腐蚀行为，为保证管道工程的经济合理性，使管道长期平稳运行，就要在设计阶段将管道所处环境与相应产生的力学行为有机地结合起来，从这一角度出发，提出合理选择线路，正确选用选材，腐蚀控制、管道保护、施工控制和管理维护等6项措施。
