The main results as follows:1. Dry weight of heading stage showed a parabolic curve relationship with yield. And grain yield correlated well with dry matter accumulation after heading and total dry weight of muturing stage. The accumulation of dry matter from N-n to heading stage correlated with photosynthetic potential.

水稻抽穗期干重与产量呈抛物线关系，抽穗后干物质积累量和成熟期总干重与产量均呈极显著线性正相关。N-n期至抽穗期干物质积累量随着光合势的增加而增加，两者相关达到显著水平，而与净同化率关系不密切。

This article in discusses the city ecology community sports concept under the frame, proposed the city ecology community sports construction should consider the material sports environment, the non- material sports environment and the inhabitant sports behavior and so on three aspects mutual functions and affect such viewpoint, in view of our country city community sports construction characteristic, proposed the city ecology community sports construction difference and the traditional community sports three property, namely "society property,, the region and the paragenesis", elaborated the city ecology community sports construction characteristic and the content, and proposed the city ecology community sports construction pattern and the different type city ecology community sports construction concrete measure.

Size, Substance, Proportion Size/Substance - The Pekingese, when lifted, is surprisingly heavy for its size.

大小，物质，比例按规定尺寸制作/物质- Pekingese，何时升高，令人惊讶地对它的大小是重的。

The research results imply that the regional tectonic stress field has resulted in deformation and flow of upper mantle material with clockwise rotation,and make the alignment of upper mantle peridotite lattice parallel to the direction of material deformation. The deformation of the crust and upper mantle is possibly vertically coherent deformation.

研究表明青藏高原东北缘上地幔物质在区域构造应力场的作用下，发生了顺时针旋转的形变以至流动，使得上地幔中橄榄岩的晶格排列方向平行于物质形变或流动方向，上地幔变形和上覆地壳变形可能存在垂直连贯变形特征。

The results showed that the chemical properties of two kinds of Perillas were quite different; Pigment stability of Japanese red Perilla to heat and light was better than that of local Perilla.
