The above results were interpreted by the calucation of CNDO/2 method of quantum chemistry. The effection of a collector-accelerating-agent mixed with a just main-collector was better than that of two collectors mixed. The structure of collector-accelerating-agent is described:① a carbonic chain or ring compound with a polar-radical,② a larger positive electric centre in this polar-radical〓 was the compound with many coordination atomics.
量子化学CNDO/2方法计算验证了上述结果,并且得到如下结论:选择有效的捕收促进剂与适当捕收剂混用,比用两种捕收剂混用更有效;并总结出捕收促进剂的结构特点为:①带一个极性基团,有足够疏水性的碳链、环化合物;②极性基因中有一个较大的正电荷中心;③极性基因中最好有多个能参与配位的极性原子。

The features of this dissertation are lie in: a The concept of"Influence Distance"was presented to quantitatively express"corner effect", systematicly studied on the influence of all factors on"influence distance". It could provide reference to angle designing from the view of heat treatment; b Deeply studied on the influence of shape factor to carbon concentration field. It could provide reference to gear designing from the view of heat treatment; c New model was set up to describe the two-dimensional concentration field of carbide dispersion carburizing. The shortcomings of"effective diffusion constant method"and"equilibrium constant method"were overcome in this model.
本文的特色在于:①提出了用"尖角影响距离"定量描述"尖角效应"的方法,并系统研究了各种因素对"尖角影响距离"的影响规律,从热处理角度为工件尖角部位的设计提供依据;②首次深入研究了齿轮的各种形状因素对浓度场的影响,从热处理角度为齿轮设计提供依据;③建立了能够更有效地模拟过饱和渗碳浓度场的数学模型,该模型克服了"有效扩散系数法"及"平衡常数法"的不足,与"最小自由能法"可互为补充。

It was suggest that the yield of tobacco in unit area was significant increasing and the quality was improved along with the altitude increase in Liuyang tobacco area. The tobacco leaves production at the place where the altitude from 400 meter and 900 meter was propitious to postpone the bearing period and growth and development of tobacco plants. It was the base of maturation endurance and could advance the tobacco leave maturation degree of all parts of tobacco plant. And it could hasten the orange tobacco leave ratio of the whole tobacco plant. It was boosted leaves unwrapping of top tobacco plant and the statuses of tobacco leaves, especially the top leaves, were significantly improved. The tissue structure of all parts leaves on tobacco plant were more loosen and the colour and luster of tobacco leaves was more vivid. The nicotinamide content in top leaves were digressive at a certain extent, on the contrary, the contents of the reductive sugar and kalium were increased at different extent. At the same time, it was benefit to play down the pesticide rudimentai of tobacco leaves and increased security of tobacco leaves.
结果表明:在浏阳烟区随着海拔高度的增加,单位面积烟叶的产量有着明显的增加,烟叶质量也有一定程度的改善;在海拔400—900m的地方进行烟叶生产,有利于延长烟株大田生育期,有效缓解浏阳烟区7、8月份的高温逼熟现象,有利于烟株的生长发育,为养好烟株的耐熟性打下良好的基础、促进各部位烟叶成熟度的提高;同时可以有效的促进烟株各部位橘黄烟叶比例的上升,对上部烟叶的开片也有着明显的促进作用,烟叶身份特别是上部烟叶的身份得到明显的改善,各部位烟叶组织结构更加疏松,烟叶色泽更加鲜亮;上部烟叶烟碱含量在一定程度上有所降低,各部位烟叶还原糖、钾含量有着不同程度的增加烟叶香气特征更加明显;香气量有一定程度的增加,吸位更加醇和、余味舒适;同时也有利于减少烟叶的农药残留量,提高烟叶的安全性。

Abstract] objective to explore the experience in the diagnosis and treatment of small bowel diverticular surgical complication.methods 24 cases of small bowel diverticular were retrospectively analysed.results the diagnosis was made preoperatively in 4 duodenal diverticula and only 1 jejunal diverticula.clinical complications included obstruction in 11 cases,bleeding in 4 cases,perforation in 4 cases.23 cases were cured.1 case was died of mof.all the diverticular with complications had histopathological signs of inflammation and 3 had signs of ulcer and 4 had the resected.conclusion the small bowel diverticular is rare.it may diagnose except common reason underwent gastrointestinal bleeding or obstruction.the gi is an effective way of examinations.operation is effective for small bowel diverticular disease.
回顾性分析24例小肠憩室病外科并发症的临床资料。结果术前6例十二指肠憩室中4例确诊,18例空回肠憩室仅1例确诊。小肠憩室伴小肠梗阻11例,憩室出血4例,憩室穿孔4例。23例治愈,1例死于多脏器功能衰竭。有并发症的憩室病理都有炎症表现,5例有溃疡,4例有异位黏膜组织。结论小肠憩室病比较少见。在胃肠出血或梗阻的情况下,可采取对常见原因排除的方法进行诊断。在不需要急诊手术的情况下,钡餐造影是最有效的检查。手术是可靠有效的治疗方法。
