However, tracheal stent implantation is different from esophageal stent implantation. As patients with airway obstruction are always complicated by dyspnea and hypoxemia, even respiratory failure, which increases risk and difficulty of stent implantation. During tracheal stent implantation, the bronchofibroscope or stent entering the stenosis site may lead to complete tracheal obstruction-induced asphyxia. Corrosion of metal wire of stent to airway mucosa and vessels may result in hemorrhea, leading to postoperative hemoptysis. Stent dislocation is mainly caused by inappropriate selection of stent, inappropriate implantation position or severe cough. Carcinoma tissue growing along stent lumens can induce re-obstruction in stent, resulting in atelectasis relapse.

气管及食管支架置入均属有创性治疗，但气管支架置入不同于食管支架置入，气管阻塞患者均有不同程度的呼吸困难和低氧血症，甚至发生呼吸衰竭，加大了支架置入的风险和难度；气管支架置入者，当纤支镜或支架进入狭窄部位时可造成气管的完全阻塞引起窒息；支架金属丝对气管黏膜血管的侵蚀可引起大出血，导致术后咯血；支架移位主要由支架选择不当、置入不到位或剧烈咳嗽引起；癌组织沿支架网眼长入造成支架内再阻塞可引起肺不张复发。

There were close relation and harmonies among the quantities characters that were significantly hereditarily correlated with tumorous stem yield. High yield breeding combining with strong ecological adaptability and good quality should be largely based on later maturity, tumorous stem diameter, whole plant weight and higher ratio of stem and leaf.

瘤茎产量与营养生长期、瘤茎膨大期、瘤茎横径、茎/叶、株鲜重呈极显著遗传正相关，与菜形指数、菜皮百分率呈极显著遗传负相关，与其余性状相关均未达显著水平；与瘤茎产量显著相关的性状间关系密切，有很好的协同性，分析提出茎瘤芥育种选择熟性晚、瘤茎横径大、茎/叶高和植株个体较大的品种，可实现品种产量高、生态适应性强和瘤茎品质较佳等三者的协调统一。

Tumorous stem yield was only significantly hereditarily positively correlated with vegetative duration, developmental duration, ratio of stem and leaf, horizontal length and whole plant fresh weight, negatively fur percentage and tumorous stem index. There were close relation and harmonies among the quantities characters that were significantly hereditarily correlated with tumorous stem yield. High yield breeding combining with strong ecological adaptability and good quality should be largely based on later maturity, tumorous stem diameter, whole plant weight and higher ratio of stem and leaf.

瘤茎产量与营养生长期、瘤茎膨大期、瘤茎横径、茎/叶、株鲜重呈极显著遗传正相关，与菜形指数、菜皮百分率呈极显著遗传负相关，与其余性状相关均未达显著水平；与瘤茎产量显著相关的性状间关系密切，有很好的协同性，分析提出茎瘤芥育种选择熟性晚、瘤茎横径大、茎/叶高和植株个体较大的品种，可实现品种产量高、生态适应性强和瘤茎品质较佳等三者的协调统一。

At a moment like this, in which, with the excuse of the actual economic crisis, the exploitation and the assault to the rights of the workers, in order to pursue with the accumulation of scandalous profits by economic groups, the Portuguese Communist Party challenged Humorgrafe to collaborate in some journeys of reflection with the participation of cartoonists from all around the world and from different political and ideological choices to, from their own philosophical and humoristic thoughts, contribute to this initiative - Exploitation and workers' rights through a humoristic line, with their artistic works about the important questions that at this moment, affect millions of Portuguese and worldwide workers: the unemployment, the low wages and the precarious job.

在片刻喜欢此，与实际经济危机、开发和攻击借口在工作者右边，为了追求以诽谤性的赢利储积由经济集团，葡萄牙共产党向Humorgrafe挑战在反射有些旅途合作与漫画家参与从所有世界和从不同的政治和思想选择，从他们自己的哲学和滑稽想法，对这主动性贡献-开发和工作者'权利通过一条滑稽线，与他们艺术性的工作关于重要问题在这片刻，影响成千上万葡萄牙和全世界工作者：失业、低薪水和飘摇的工作。

A simple artificial immune network algorithm, suitable for clustering problems with a small quantity of samples, is obtained by using the idiotype immune network. Further, a fuzzy immune network classification algorithm applied to sample classification learning is proposed by uniting the algorithm and fuzzy logical rules.

其次，利用抗原群及抗体群的作用关系，结合免疫记忆细胞的记忆功能，并借助于克隆选择原理、免疫网络的调节机制及约束条件处理方法，设计约束多目标优化免疫算法处理约束多目标优化问题，收敛性论证、性能测试、比较及实际应用表明此算法是有效的。

The following conclusions have been drawn:(1) According their field and petrologic characteristics and building upon previous works, Late Mesozoic and Cenozoic mafic dikes form Jiangxi province are complex in rock associations which are compose of lamprophyre and gabbro-diabase and diabase and diabase-porphyrite, are mainly distributed into three north-north-eastern strike belt including Xingzi-Shanggao-Pingxiang and Dexing-Yujiang-Xiangshan-Jian-Shangyou and Caotaobei-Dajishan.

本论文选择了江西省晚中生代以来的基性岩脉为研究对象，运用矿物学、元素和同位素地球化学及K-Ar测年等研究方法，首次较为系统地研究了江西省晚中生代以来的基性岩脉、与地壳拉张有关的基性侵入岩体的地质地球化学特征，并利用对其形成时代、源区性质的研究来探讨中国东南部地壳拉张期次、地幔性质等地球动力学背景中的关键性问题。
