Zhu De-Qun's classmate, Wu Quan-Zhong, described him in a poem with the lines"The thick strings loudly thrummed like the pattering rain; the fine strings softly tinkled in a murmuring strain."It describes the rhythm of the lines in Zu De-Qun' s works and the interlacing of dots and lines.

朱德群的同窗吴冠中就曾用「大弦嘈嘈似急雨，小弦切切似私语」的诗句，形容朱德群作品中，因线条律动产生的节奏感，以及点线交错与窜动，结合画面光影明暗，形成如音符般时急时缓、高低起伏的旋律。

The first part elucidates the origin of the term sonata and the relationship between the early sonata and other contemporary instrumental music genres, pointing out the fact that the intertwining and mixing among sonata, canzona, sinfonia and concerto was caused by the obscure defining and distinguishing of different music genres. Since they overlapped in many aspects such as composition and performance, they were often confused with each other in actual practices.

第一部分阐述了奏鸣曲这一术语的起源以及早期奏鸣曲与同时代其它器乐体裁之间的关系，指出奏鸣曲与坎佐纳、交响曲、协奏曲之间的交错与混合在于体裁本身及体裁之间尚未形成明确的界定，它们在创作手法、演奏形式等方面存在着重合，因而在实际运用中经常被混同。

In this paper ,we discuss mainly the problem of roots of Jones polynomial and the properties of incompressible surface in almost alternating link exteriors.

中文摘要：本文我们主要讨论了纽结的琼斯多项式根的问题以及几乎交错环链补中的不可压缩曲面的性质。

As a result, some ideas about the fabrication are put forward.The EPMA experiment results show that the main element such as W, Mo, Ti, Ni, Cu, Fe element are changed gradually in W-Mo and W-Mo-Ti FGM. In the layer rich in W, the grain are intervained and are mixed mechanismly. The same is to the layer rich in Mo and W-Mo. These grain felt up by some sinter. In Mo-Ti layer rich in Mo, the grains are also mixed mechanismly. Ni, Cu, Fe element assembled at interface. Ni melt by Cu plays an vital role in sinter effect. The microstructure characteristics result show that the compactness of W-Mo and W-Mo-Ti FGM is good.

电子探针实验结果表明W-Mo系、W-Mo-Ti系梯度功能材料中主要元素W、Mo、Ti、Ni、Fe、Cu分布整体上具有梯度变化规律，发现富W区、富Mo区、W-Mo混合区中颗粒交错分布，基本上以机械混合的形式存在，颗粒之间主要靠烧结剂的粘结作用实现致密化；以Mo为主要组分的Mo-Ti混合区，也是以机械混合的形式存在；Cu溶解于Ni形成固溶体更好地起到活化烧结能力，Ni、Cu、Fe在宏观层间界面富集，有利于烧结致密化。

The bursts and riverway changes of the Yellow River, River Hai and River Huai left many interlaced ancient riverways, deltas and depressions, which make the surface form and shapes of sediments rather complex.

由于黄河、海河、淮河的决口、改道，在平原上留下许多纵横交错的古河道、古三角洲和洼地。使平原区的岗洼交错分布，地表形态和沉积物的结构都十分复杂。

The research shows that:①The land use/cover of Asia at the ecological security level takes on a macroscopical three-circle pattern.

研究表明：①亚洲生态安全条件下的土地利用/覆盖宏观三圈格局为：内圈以自然保护为主的沙漠地带；中圈以建设人工草地为主，辅以大面积自然恢复的草原地带；外圈以农、林、牧复合为主的交错地带。

Op Art is a mathematically oriented form, usually abstract, which uses repetition of simple forms and colors to create vibrating effects, moiré patterns, an exaggerated sense of depth, foreground-background confusion, and other visual phenomena.

视幻艺术面向数学形式，通常很抽象，利用简单线条及颜色的重复来产生振动效果，纹理错位，夸大的深度感，前景-背景的交错，以及其它的视觉现象。
