 The present study thus investigated the origin of this restriction in interlimb transfer, by comparing the effects of eight-direction and one-direction training conditions with one arm on the subsequent performance with the other arm.
 Because the positive-negative sign method, we applied to computer graphics has the following shortcomings: only four directions; the distance between every moved point and the real curve less one step, that is moved by the plotter every time; can't keep symmetribility and reversibility for different rounded directions, the author has designed a new method, called the minimum remnat method for the application to computer graphics. The essence of this method is as follows: each time when the plotter moves one... Because the positive-negative sign method, we applied to computer graphics has the following shortcomings: only four directions; the distance between every moved point and the real curve less one step, that is moved by the plotter every time; can't keep symmetribility and reversibility for different rounded directions, the author has designed a new method, called the minimum remnat method for the application to computer graphics. The essence of this method is as follows: each time when the plotter moves one step, we choose the minimnm remnant direction of the eight directions to be the next one (in fact we choose the minimum remnant direction from the last direction, its right and its left one). This method has eight directions of motion; the distance between every moved point and the real curve is less than half step, and it can keep symmetry and reversibility for different rounded directions.This method has found successful application in the graphic software developed by the author and other places. 由于用于计算机绘图的正负法有如下缺点:只有四个走向,每步与真实曲线误差不超过一步,不保持对称性,且没有不同绕向的可逆性.作者设计了一种称为最小残量法的绘图方法,即每走一步后,就在八个走向中选残量为最小的走向为下一步走向(在实现中实际上只是在原走步方向,以及它的左、右邻走步方向,这三个方向中选残量为最小的方向).这个方法有八个走向,每步与真实曲线误差不超过半步,且有对称性与不同绕向的可逆性. 这个方法已在作者研制的统一绘图软件中予以实现,且在其它兄弟单位中得到应用.

The formation of spherulites of graphite in cast iron containing Ce and Mgwas studied.X-ray pattern and electron probe showed the presence of Ce in theform of CeS of NaCl B1 type and of CeC_2 of b.c.tetragonal C11a type crystalstructures.On the basis of the lattice constants of CeS,MgS,graphite and CeC_2,the sizes of the hexagonal nets of Ce,Mg and of graphite are calculated.It isfound that certain Ce or Mg atoms in the hexagonal nets planes normal to[111],[111],…are in conformity with the C atoms of the hexagonal nets of graphite.Due to the difference of electronegativities between Ce and C or between Mg andC of graphite,the electrostatic coulombic force from Ce or Mg will attract the Catoms precipitated from the melted liquids of cast iron to deposite as hexagonallayers on layers of graphite along the eight directions[111],[111],…of CeS orMgS.The result is the formation of spherulites of graphite.The conformation theC atoms in CeC_2 with the Ce or Mg atoms in the hexagonal nets of CeS or MgSalong the directions[100],[010],…is also briefly introduced. 本文对稀土镁球墨铸铁中石墨球化的机构进行了研究.电子探针分析表明,石墨球中心存在Ce、Mg、S;氧则均匀分布在铸铁表面而不集中在球墨中心,X射线衍射分析证实球墨是以CeS和MgS为核心.计算结果表明CeS或MgS中的Ce或Mg在垂直体心对角线[111],[11(?)],……八个方向呈六方形网状结构.若与石墨的六方网重叠吋,就会有一部分Ce或Mg原子的位置和石墨的碳原子重叠,即共格.由于Ce,Mg与碳电负性差△X较大,则碳原子易被Mg或Ce原子吸引形成石墨六方网状结构堆积在Ce或Mg的六方网上,并沿上述八个方向伸展开去结晶成石墨球.

Firstly, he roughly investigated the orography and river patterns, and livelily described the hot springs, vulcano-es, karst caves and mineral resources in detail. Xu Xiake's Travels has been a very famous and lovely realistic literature all over the world.Duing the period of 1978 to 1980, the author organized the experiments... Xu Xiake, the geographer in Ming Dyasty, was 55 years old, and took 39 days to explore the Tengchong area on-the-spot after crossing the Nujiang River and the Gaoligong Mountain Range. Firstly, he roughly investigated the orography and river patterns, and livelily described the hot springs, vulcano-es, karst caves and mineral resources in detail. Xu Xiake's Travels has been a very famous and lovely realistic literature all over the world.Duing the period of 1978 to 1980, the author organized the experiments of airborne remote sensing in Tengchong area. Aerial photographic mosaic with the scale of 1 : 50000 and 25 thematic maps in the scale of 1 : 100000 have bave gotten in the area using 1: 35000 infrared color photography, multi-band scanning and therm-infrared images, also including the processing and analysing of Landsat images, quantitative researches have been taken for natural resources, environmental ecology, geoghemistry and landscales etc.Films of "Remote "Remote Sensing'' and "Vulcanoes and Hot Spring in Tengchong" have been distributed, Atlas of Airborne Remote Sensing in Tngchong Area has been published. It is a very conscientious and careful verification on the scientific value of Xu Xiake's Travels.Based on the content described in Xu Xiake's Travels, this paper discusses the several geographic concepts with verification by field notes and sket-ches got from the same area by myself.1.The information accessing from his Travels along the cross section of Caoligong Mountain is so abundant that enough to draw up a composite physio-geographic profile approaching demand of on-the-spot surveys (Fig.4).2.Travels described mountain ridges and drainage systems in Tengchong intermontane bason with eight directions. Its relative geographic position is correct, and their outlines checked by topographic map approximately ( Fig.2).3.Travels adopted three layers in logic structure from micro description to macro summarization of geographic terms.4.Travels is a integrated scientific records, involve many aspects of natural phenomenon, importantly attach to observing first hand materials himself.Historical contribution of Xu Xiake's Travels is matter-of-fact attitude surmounting epoch and dedication spirit for sciences. These are well worth cherishing and learning for ever. 作者选取本人身历其境作过工作的怒江、腾冲地区来验证《徐霞客游记》,从徐氏进步的地理概念、游记严谨的逻辑结构、游记作者观察的细致深入等方面论述了徐霞客的献身精神和不朽贡献。 << 更多相关文摘
