提出了一种基于参数展开的新的同伦分折技术：结合参数展开技术和同伦理论将一非线性动力系统(不要求系统内含有小参数)的求解问题转化为组线性微分方程的求解问题，并将之运用到强非线性振动领域。

Are given out, and then a survey and review of the literature up to 1980 is given of the linear theory of the ideal and resistive hydromagnetic instability of tokamak. Some important characteristics of MHD instabilities are discussed in more details. Since sawtooth oscillation is discovered in ST tokamak, many theory models are proposed to explain the disruptive part of sawtooth, however, there is no satisfactory theory of the internal disruption.

Numerical simulations and analytical results show: in longitudinal and oblique seas, ship may be subjected to primary parametric resonance with large roll amplitude and even capsizing, when encounter frequency is near the twice of roll natural frequency, wave length and ship length are of the same order and the wave height is larger than a certain value; in oblique seas, ship roll motion is a forcedly-parametrically excited oscillation, primary resonance occur as the encounter frequency is near the roll natural frequency, which may lead to large rolling and capsizing too.

数值仿真和解析分析结果表明：在纵浪和斜浪中，当遭遇频率接近船舶横摇固有频率的两倍，波长和船长接近，波高超过某一阈值的时候，船舶会发生主参数共振，产生大幅横摇甚至倾覆；在斜浪中，船舶发生的是参强激励横摇运动，遭遇频率接近横摇固有频率时，还会激起横摇主共振，同样会产生大幅横摇甚至倾覆。

During the Si homoepitaxial growth on a double domain Si (100)(2×1) surface, a monoatomic layer mode of RHEED intensity oscillation along [100] azimuth and a ＂monoatomic-layer-like＂ mode along [110] azimuth are observed.

This paper enumerates nine macroscopic climatic indicators in the study of China's Quaternary climate:Quaternary glacial vestiges,periglacial structure, mammal fossils,plant fossils,mollusk fossils,foramin- iferal fossils,lithology,karst and sea-level oscillation.

本文首先列述了中国第四纪气候研究中9种主要宏观气候标志：冰川作用遗迹、冰缘构造，哺乳动物、植物、软体动物、有孔虫化石，岩性、岩溶及海平面升降等方面的特征。

Consequently the beam transmission problem is solved well. The general design curves of microwave plasma drift tube are developed by the theory and they can be used for development of the plasma microwave devices. Ion channel, as a important phenomenon in the interaction between electron beam and plasma, is first introduced into the study of PASOTRON, to replace the concept'plasma channel'used in general plasma microwave devices. A model is created to describe the channel performance. The channel is not stable, it is oscillatory and the oscillation frequency is larger than that of plasma.

作为电子束与等离子体相互作用的一个重要现象，本文首次将离子通道的概念引入到了PASOTRON的研究中，以区别常规的等离子体通道概念，并通过建立的模型推出离子通道并非一稳定规则的通道，而是具有振荡特性，振荡频率高于等离子体频率，推出了当满足一定条件时束外可能没有电子而成为纯的离子通道，这种状态对微波器件有重要的价值。
