  feature phase
     On the feature phase space in the seismic pattern recognition of underground nuclear explosions
     核爆地震模式识别中的特征相空间研究
短句来源
     We present the origin of the equivalence of feature space and phase space based on the determination of the minimum of uncorrelated features and the choice of training samples in the seismic pattern recognition of underground nuclear explosions. The validity of feature space and phase space is tested by numerical experiments. Experimental results indicate that the attractor analysis approach of feature phase space is an efficient way for pattern recognition.

Based on more than twenty years' experiences in rubber planting in China, this paper deals with the relations between the factors concerning the natural environmental conditions in different rubber planting areas and the characteristics of phenotypes of rubber trees in their growth and yield. In addition, comparisons have been made between the advantages or disadvantages of the natural environments in some tropical rubber-producing countries and those of China.

Based on more than twenty years' experiences in rubber planting in China, this paper deals with the relations between the factors concerning the natural environmental conditions in different rubber planting areas and the characteristics of phenotypes of rubber trees in their growth and yield. In addition, comparisons have been made between the advantages or disadvantages of the natural environments in some tropical rubber-producing countries and those of China. It has been considered successful and of great importance that rubber trees can be cultivated on large scale in the monsoon climate districts of tropical and south subtropical zones at 17°N. According to the geographic and geomorphological factors and the ecological aspects of various tropical crops, the criteria have been established for dividing the areas of China's tropical zone and south subtropical zone. This paper also emphasized the importance of exploiting China's valuable tropical natural resources and making full use of them in line with local conditions. Hence a reasonable distribution of various kinds of tropical crops has been put forward on the basis of latitude and elevation together with local natural conditions. In addition, a program has also been made for speeding up the establishment of the production bases of rubber, coconut, agave and other tropical crops, so as to meet the needs of the four modernizations in China.

本文在总结我国植胶20多年有关经验的基础上,论述了各植胶区的自然条件因素与橡胶树生长、产胶等表现型特征之间的关系,并与一些热带植胶国家自然条件的利弊作了对比分析,肯定了我国在北纬17°以北的热带、亚热带季风气候区大面积植胶成功的重要意义,并根据地理、地貌因素,各种热带作物的生态表现,提出了我国热带、南亚热带划分的依据。强调了因地制宜,充分利用开发我国宝贵的热带自然资源的重要性。为此,进一步提出了按纬度、海拔高度以及当地自然特征相结合的各种热带作物的合理布局,以及加速建立橡胶、椰子、剑麻等热作生产基地的方案,以适应我国四个现代化建设的需要。

The present paper contributes the knowledge of wood structure of Manglie-tiastrum sinicum Law, a new monotypic genus of the family Magnoliaceae.

本文对最近在我国云南省西畴县热带雨林中发现的木兰科中的一个新的单种属——华盖木(Manglie-tastrum sinicum Law)的木材解剖特征进行首次报道:它具有较稀的管孔数目;单管孔占优势;导管侧壁具细螺纹加厚,底壁穿孔板横条数较多,为6—12枚,高达17枚;轴向薄壁组织轮界状,宽达9—12列细胞,还偶有稀疏傍管薄壁组织;木射线为Kribs异形ⅡA型,且在少数多列线中具略长的单列翼部分。这些解剖的,以及联系到外部形态特征,虽然和近缘的木莲属Manglietia Blume存在着一定的差别。但与本科其他各属比较,则又与“拟木莲属”(“Paramanglietia”Hu & Cheng)、香木兰属Aromadendron Blume、榻榔木属Talauma Juss.及木兰属Magnolia Linn.的多数种类,在木材构造中留存有较多的原始特征相类似。

In this paper, by using the method of trend surface analysis, the data of mobile geomagnetic measurements in the joint area of provinces of shandong, Jiangsu, Anhui and He-nan from August 1976 to November 1979 are analysed. Preliminary analysis shows that the geomagnetic variation in the are a is of normal magnetic variation. The trend part of the variation is the secular geomagnetic variation. The secular variation rates are not entirely the same for each locality in the area. But the spatial distribution of the rates reveals certain regularity. The character of the secular variation agrees with that obtained on the basis of other geomagnetic data. No anomalous local secular geomagnetic variation has been found in the area. The accuracy of determination of this observational system is about ± 3.0 r . The variations of the residuals of most of the points are within the observational error .But before and after the Guzhen (固镇) Earthquake (Ms=5.0) on March 2, 1979, the variations of residuals of the points around the epicentre-seem to be anomalous, exceeding the observational error.

本文用趋势面分析的方法对1976年8月起在华东鲁、苏、皖、豫交界一带开展的流动地磁测量结果进行了分析.这一分析表明,观测结果主要反映了地磁场的正常变化,趋势变化部分是地磁场长期变化.测区内各测点的长期变化速率不尽相同,而是呈现一定空间分布上的规律性.这一结果与其他资料所得的长期变化空间分布特征相一致.测区内未发现有局部地磁长期变化异常.整个测区的观测精度约±3.0伽马,大部分测点观测结果中的残差变化基本在观测精度范围内.但1979年3月2日固镇 M_S=5.0地震前后震中附近测点呈现了超出观测误差的可能磁异常变化.
