查询词典 straw line

This article focuses on the line-line, line-region and region-region topological relations algorithm, which come down to the same question: whether there are intersections between line and line. The sweep-line algorithm was studied by many people, but has some deficiencies to be improved, in order to handle some special cases and increase program efficiency. My works as follows: rectangular envelope to reduce executive times , vector cross multiplication to determine intersection between line and line, coordinates and slope method to deal with some special cases. C program examples are showed together.(5) Finally, to prove capability and efficiency of the model and calculation method, some test systems are developed. For example, complex spatial topological relation query, parcels' exact area with the area of linear object reduced in land use, quality inspection to cadastral data according to topological rule, spatio-temporal change query of cadastral data.

将线线、线面、面面之间的拓扑关系实现的算法归结为线与线之间求交的基本问题；为处理一些特殊的拓扑关系情况，提高扫描线算法的效率，探讨了包络矩形粗滤、判断线线是否相交的矢量叉乘法、线节点重合或共线的斜率坐标判断法等改进方法；同时还设计了一种新的节点微小圆求交的算法，可应用于图斑与线状地物细分拓扑关系及地类面积的计算；（5）本文设计了实验系统，包括复杂对象的拓扑关系表达与计算程序、图斑地类面积的计算程序、基于空间拓扑关系规则的地籍数据库质量检查功能，以及时空拓扑关系和变化语义分析等原型，验证了拓扑关系表达模型和计算方法的可行性和实用性。

Under a fixed model of chromospheric flare, we investigate the influences of Hα and CaIIK line profilles on various velocity distributions from semiempirical view. The results show that: Hα line is very sensitive to the velocity in upper chromosphere; the profile of CaIIK line have responses to velocity in any layer of chromosphere, but the degree of CaIIK line asymmetry is much weaker than that of Hα and can be ignored if velocity is as small as 10km/s; chromospheric condensation in lower part of transition region have strong influence on Hα line but contrary to CaIIK line, the typical characteristic of H line effected by chromospheric condensation in transition region is reversed blue asymmetry, i.e. the intensity of blue peak is stronger than that of red peak; the stronger the chromosphoric condensation is, the more obvious the Hα line asymmetry appears; and so on.

在确定的大气模型下，从半经验角度系统地研究了大气各个层次的速度场和运动结构对Hα和CaⅡK谱线轮廓的影响，得到；Hα线对色球上部速度场敏感，而对色球下部和温度极小区附近速度场不敏感；CaⅡK对整个色球速度场均有反应，但不对称性较Hα弱，且速度小于10km/s时不对称性很不明显；CaⅡK受过渡区色球凝聚的影响较弱，而Hα对色球凝聚十分敏感；色球凝聚影响Hα轮廓的典型特征是呈反转结构的兰不对称性，即兰峰强于红峰；色球凝聚越强，Hα不对称性也越显著：等。

A Man of straw or straw is "rice straw is a Man who".

Man of straw 或 straw man 就是"稻草人"。

The results indicated that:(1) plant height and tillering number decreased, and root length, root surface area, root volume and rootlet number increased under drought stress; straw mulched on surface soil and pig manure mixed in soil could improve the growth and morphological property of rice root, while straw mixed in soil and pig manure mulching had no significant effects;(2) the contents of chlorophylls and the activities of SOD, POD and CAT decreased significantly under drought stress, and straw mulching on surface soil and pig manure mixed in soil could restrain these decreases.

结果表明：①干旱胁迫下水稻株高降低、分蘖数减少，根系则表现出主根伸长、支根增多、根表面积和根体积增加；秸秆表施和猪粪混施可明显改善水稻的生长和根系形态，而秸秆混施和猪粪表施的改善作用不显著；②干旱胁迫下叶片叶绿素含量显著降低，超氧化物歧化酶、过氧化物酶及过氧化氢酶活性均显著下降，秸秆表施和猪粪混施能够在一定程度上抑制这种下降幅度。

Straw smashing device sectionally set front of sower resolved the problems that long straw gathered on the opener and the sower could not pass. A sectional feeder-beater assembled before smashing made the straw fed into the smashing smoothly. The parameters of configuration and movement of working parts was properly designed and the position was properly arranged made the power consumption...

They took and shoved the bag through a rip in the straw tick that was under the feather-bed, and crammed it in a foot or two amongst the straw and said it was all right now, because a nigger only makes up the feather-bed, and don't turn over the straw tick only about twice a year, and so it warn't in no danger of getting stole now.

他们拿过袋子，往羽绒褥子底下一张草垫子的裂缝里使劲塞，塞了足足有一两英尺深。还说，这么一放，不会有什么问题了，因为一个黑奴只会整理整理羽绒褥子，不会动草垫子，草垫子一年只翻两回，把钱塞在里面，就不会有被偷的危险啦。

Chemical treatments could efficiently decrease the amount of waxiness, the cellulose, semi-cellulose and silicon dioxide of raw rice straw, while water-soluble compounds of the treated rice straw was increased and therefore the treated straw could be easily attacked by soil microorganisms.
