This study deals with a complete analytical mode-shape analysis of thelateral oscillation for a two-axle-bogie locomotive. The principal purpose of thispaper is to give a clear physical interpretation of each basic mode-shape of la-teral vibration, its characteristic of instability and the influences of parame-ters on the critical speeds corresponding to each basic mode-shape. A mathema-tical model of 17 degrees of freedom is used and the differential equations ofmotion were solved numerieally by QR double-step method. A computer programwas carried out with a sub-routine to normalize the eigenvectors, The numericalresults were analyzed by the method of "Mode-Shape Analysis". One of the con-elusions is that the fundamental mode shape of lateral oscillation for a two-axle-bogie locomotive may be summarized into 8 modes, among which only 5 maybe instable. Furthermore, the instability of the other 5 instable modes may bedivided as restorable and irrestorable ones. As the parametric study being diff-erent from the similar studies published before, The proper task is to study theinfluences of parameters on the instability of 5 instable fundamental mode-sha-pes separately, The influences of 21 parameters are given. Based on this analysis,The instructions for optimizing each parameter to care the instability of the 5instable modes are also given respectively These obtained informations are offeredin a form which are most convenientto be used in practice.

本文涉及了两轴转向架机车横向振动振型分析的完整解析。主要目的是为了对横向振动的各个基本振型、它的不稳定特征以及参数对各基本振型临界速度的影响给以较清晰的物理描述。利用了一个17个自由度的数学模型。并用二步QR算法对微分运动方程作了数值的求解。编制了一个带有规格化特征向量子程序的计算程序。我们利用振型分析法对数值结果作了分析。结论之一是,对于两轴转向架机车其横向振动的基本振型可以归纳为8个振型,这8个中只有5个是不稳定的。此外,这5个不稳定振型的不稳定性又可以分为可恢复型和不可恢复型两种。我们为参数研究所规定的任务不同于以前已发表过的类似研究,是要熟悉参数对5种不稳定基本振型的影响。本文给出了21个参数的影响,同时在分析的基础上,也给出了各个参数最优化的说明,以便分别照顾到5种不稳定性振型的不稳定性。全部资料是以在实际中可以应用的形式提出的。

1. Seven cytoplasmic male-sterility(CMS) lines derived from different cytoplasmic sources were test-crossed with 64 inbred lines. The pollen restoration and segregation of male fertility in F_1. F_2 and Bc_1 population had been examinated. The processes of microsporogenesis of different CMS lines had been observed, and by using palyacrylomide gel electrophoresis their zymogramic types of peroxidase isozyme of the anthers in tasseling stage had been analysed.The results of these studies have indicated that there are significant differences between these CMS groups in genetical, biochemical and cytological phases as just mentioned above.2. A method used to test for "isoplasmogene-allele" of fertility between gametophytic CMS lines has demonstrated that MO17 CMS "Tang Xu". MO17 CMS "Shuang". 77 CMS-M, and Xian 202 "Er Ma Ya" are belonging to a series of allelic groups.Phenotypes of their fertility in F_1. F_2. BC_1 generations have indicated that their fertility might controlled by interactive system of Rf_3 and S-plasmogene, and their unstabilityof fertility might be induced by polygenes.3. The S group of CMS obtained from a restoring of fertility by J. B. Beckett is a very large group. It has provided abandent plasm-s sources for use. We may use some proper method to breed inbred lines and take care to seleete suitable parents to eliminate the influence of polygenes. The unstability of fertility in CMS-S lines may be avoided.

本研究用自风_1、风可_1等64个不同种质来源的自交系对MO17CMS唐徐等七种不同胞质来源的CMS系进行了广泛的测交,鉴定了它们测交后代的育性反应和恢复型组合的F_2、不育系/(不育系×恢复系)、(不育系×恢复系)/保持系等BC_1群体的育性分离比例;检查了不育系和由它们组配的恢复型组合F_1的花粉碘染情况;观察了各类型CMS系花粉败育细胞学特点;分析了它们散粉前花药的过氧化物酶同功酶酶谱特征。研究结果表明: 1、MO17CMS唐徐,MO17CMS双,成202CMS二马牙三种不育系均属于S组配子体不育类型。恢复性受一对显性基因控制。MO17CMS新单是属于T组孢子体不育类型。只要进一步查明自交系恢313、自风_1、MO17的基因型,就可作为胞质分类的测验系。2、对配子体不育系采用了一种“同质等位”性测定的方法,证明MO17CMS唐徐、MO17CMS双、77CMS—M和成202CMS二马矛是一组胞质基因相同。核基因等位的同质等位系。它们在育性上的差异和不稳定现象主要是由微效基因的作用所造成的。这种微效基因对不同败育类型的不育系发生的作用效应是不相同的。只要认真地注意亲本的选择,采用适当...

The present work was undertaken for the clinical practice. 59 heathy adult rabbits were used in this study. These animals were divided into three groups; (1) ligating the right branch of the hepatic artery, (2) ligating tne right branch of the portal vein, and (3) ligating both the right branch of the hepatic artery and portal vein.

It has been concerned by the people for a long time to unfold the interruption of hepatic blood flow in security. The present work was undertaken for the clinical practice. 59 heathy adult rabbits were used in this study. These animals were divided into three groups; (1) ligating the right branch of the hepatic artery, (2) ligating tne right branch of the portal vein, and (3) ligating both the right branch of the hepatic artery and portal vein. The hepatic weight, histology, ultrastructure and serum enzymes were observed at regular intervals after the operation. Vaso-graphys were also performed in the selected animals to investigate reconstruction of collateral vessels.The experiment results;1. During the earlier stage after the ligation of the right hepatic artery, in-farct areas of various extent were occurred in the lobe from which the arterial blood supply had been excluded. Finally, they can be classified into two types, the restored type (55.6%) and the infarction type (44.4%). After the ligation of the right portal vein, the ligated lobes became atrophic, and nonligated lobes became compensatory hepertrophic, and by a balance of the two processes the original weight of the liver was maintained. After the ligation of both the right branch of the hepatic artery and portal vein, the infarction was total in lobes supplied by the occluded vessels in 83 per cent of animals. There were partial normal liver tissues remained only in three rabbits.2.On the third postoperative day, the serum GPT activity rose much higher in the animals of 3 rd group than that in the 1 st or 2 nd group.3.The collateral circulation was reconstructed at the 25 th day after ligating the right hepatic artery, while there was no collateral circulation reconstructed after ligating the right portal vein.4.The rabbits could tolerate about 20 per cent of acute infarction of liver tissues.The authors are conveined that;1.There were some dangerous after the ligation of the hepatic artery. The extent of hepatic infarction may be reduced after interrupting the hepatic arterial flow if we could take some methods to alter the stagnation of portal blood flow and to enhance the hepatic cell against hypoxymia.2.The ligation of the branch of the portal vein may be practiced in the clinic. There was no bad result to the organism.3.The ligation of both the branch of the hepatic artery and portal vein should not be performed, and this may lead to severe consequence.4.In the early period after operation dynamic observating the serum GPT activity may be used to evaluate the degree of the liver damage.

安全开展肝血流阻断术是人们关注的问题。为指导临床工作,本实验共用59只家兔进行研究。分3个实验组,分别或同时结扎肝动脉、门静脉右叶分枝,观察术后肝脏重量、组织学、超微结构及血清酶活性的变化,並选择性作血管造影,了解血流阻断情况。 实验结果为:1.肝动脉分枝结扎后早期,结扎叶均发生不同程度的梗死。总的趋势可分为两型:恢复型(占本组55.6%)和梗死型(占本组的44.4%);门静脉分枝结扎后引起结扎叶的萎缩、非结扎叶代偿性肥大,两者处于相对的平衡状态;两种血管同时被结扎后,83%动物的梗死区占据整个结扎叶,仅3只残留有部分色泽尚正常的肝组织。 2.肝动脉、门静脉分枝同时结扎组与单个血管结扎组比较,术后第3天血清GPT活性相差显著(P<0.01)。 3.肝动脉分枝结扎后第25天,动脉侧枝循环已经建立,门静脉分枝结扎后则未见入肝的侧枝循环形成。 4.20%左右肝组织发生急性梗死对于家兔是可以耐受的。 本文认为:1.肝动脉结扎术存在一定的危险性。在肝动脉血流完全阻断情况下,从术前、术中开始提供改善门静脉血流淤滞状态、增强肝细胞对低氧血症抵抗力的措施可以减轻术后肝梗死的严重程度。 2.门静脉分枝结扎对机体不产...
