A circle is placed at the launch point to improve the interaction between the electron beam and the fields supported by the slow wave structure, thus to control the beam current density at the launch point, and to minimize the loss of the electron beam energy. The inaner radii of the extractor vanes are slightly larger than those of other SWS vanes, which increases the axial group velocity and enhances the microwave output power and efficiency. Implementation of two RF choke vanes stops the leakage of microwave pulse power toward the diode, and makes the device more compact than the conventional MILO.

该振荡器在阴极电子发射起点加圆环，控制此处电子束的发射密度，来减少电子能量的损耗，改善束－波互作用；逐渐加大慢波结构的后两个叶片的内半径，增大微波群速度，便于谐振腔中的能量输出，提高微波输出效率；采用两个扼流片有效地阻止了微波功率向二极管区泄漏，相应减小了器件的尺寸。

Within a month of the same time, at the Old Bailey, two persons, on two separate occasions, 3 were rejected as jurymen, and one of them grossly insulted by the judge and by one of the counsel, because they honestly declared that they had no theological belief; and a third, a foreigner, 4 for the same reason, was denied justice against a thief.

在同时的一个月之内，在旧百雷地方，又有两个人分别在两个场合上被拒绝充当陪审员，②其中一人并受到推事和律师之一的重大侮辱，只因他们诚实地自陈没有什么神学的信仰；同时还有第三个，一个外国人，则因同样的理由被拒绝对一个窃贼进行控诉。

All metaphases showed three distinct green signals, which have the same size and intensity, corresponding to a normal chromosome 8 and two isochromosomes 8q, and five red signals, of which one was located on a normal chromosome 8 and the another two quite symmetrically on the both arms of each isochromosome 8q, respectively.

To classify metonymies, it is necessary to take into account two criteria, the degree of genericity and the ontological nature of domains, according to which metonymies can be classified into two kinds, high-level metonymies and low-level metonymies.

关于转喻的分类，本文提出两个标准，类属程度和认知域的本体特征。根据这两个标准，转喻可简约地分为高层转喻与低层转喻。高层转喻直接利用类属ICM进行映射，影响语言结构，从这层意义上说，它是语法转喻。

Based on these, an improving μ-synthesis is presented, with which the high-purity distillation is designed well. 2. The robust performance problem of MIMO plant is explained with the plant direction angle, which shows that the robust performance varies with different input uncertainties and the μ-synthesis should be applied correctly according to the uncertainty structure. 3. Condition number and bandwidth are the important items for robust performance design in MIMO system. The H〓 two-block problems can not deal with the robust performance design of MIMO system because of the condition number cancellation. A general μ-synthesis procedure for MIMO system with uncertainties is presented. 4. For the SISO system, the object function in robust performance is amplified by at most 〓 than that of H〓 two-block problems in value: So the robust performance of SISO system can be done with the H〓 two-block problems to avoid the complicated μ-synthesis procedure. 5. All the conclusions and methods presented in this paper are demonstrated by some typical design examples.

从而形成一种改进的μ综合方去，并对精馏塔病态对象进行了鲁棒性能设计，得到令人满意的结果；（2）利用对象的方向角解释了MIMO对象鲁棒性能设计出现问题的原因，并提出不同输入摄动形式下系统的鲁棒性能问题也并不相同，因此利用μ综合处理鲁棒性能设计时，应根据不同的摄动情况采用不同的结构进行设计：（3）条件数问题和带宽问题是MIMO系统鲁棒性能设计的两个主要问题，指出由于条件数对消的存在使得一般H〓两块问题无法处理MIMO系统的鲁棒性能设计，而μ综合方法则是处理MIMO系统鲁棒性能设计的有效方法，并给出了其处理MIMO系统鲁棒性能设计的一般性方法；（4）提出对于SISO系统H〓两块问题（S/T问题、S/KS问题）的设计指标函数与鲁棒性能设计的μ指标函数在数值上最大差〓倍，因此对于一般SISO系统的鲁棒性能设计可以简单地用一般的H〓的两块问题处理，而避免μ综合设计的复杂过程；（5）本文中提出的结论和算法都利用H〓/μ发展中的典型例子：Doyle-Stein问题，Safonov的战斗机模型，精馏塔对象等进行了设计验证。

The central 5, 5'-disubstituted bipyridine units of each ligand coordinate theNi or Fe ion, while all the terminal 6-monosubstituted bipyridine units of the ligands keep free of coordination, as the result trinuclear triple-stranded helicate 〓 can not form. This is considered to be caused by the steric hindrance of the methylene substituents α to the chelating nitrogens of the terminal bipyridine units and the strain caused by linkage mode.

配体L〓与Ag作用得到〓，两个配体链相互缠绕着两个Ag离子周围形成双股螺旋结构并以头尾式排列(见图3)，由于配体中位于配位N原子α或β位的末端甲基或次甲基取代基的空间位阻阻碍了头对头式异构体的形成，也正是由于配体头尾式排列而使Ag双股螺旋得以形成，这一结果表明该螺旋体的组装过程中自发地采取了空间阻碍尽可能小的那个构型。
