From the point of view of geobotany, with the method of correlative factors of growth of plants, a countrywide theoretic ecological division was done for the introduction of Camptotheca acuminata and three kinds of areas of ecological preferent zone, ecological adaptive zone and ecological unadaptable zone were divided. With the theory of synecology, the characteristic on environment, constitution, life form spectrum, diversity, similarity of plots of communities were researched. Applying the method of species association, discrete distribution, indensity index, fractal geometry, etc. to research relations between the species of the communities, space distribution of Camptotheca acuminata, structure of age of Camptotheca acuminata, in different communities. Using the theories of autoecology, distibutons of seeds on land and growth of seedlings in vertical and horizontal directions, biomass of organ of Camptotheca acuminata were analyzed. On the opinions of conservation biology, the external and internal factors impressing Camptotheca acuminata were analyzed to research the mechanism of the endangered species, and with using of CTM Model, the future development direction of Camptotheca acuminata in different communities were forecasted, and. Standing on the position of resources ecology, discussing the regularity of camptothein in Camptotheca acuminata of different sites and seeding of different resources, also the the derive technics of camptothecin.

What of architectural beauty I now see, I know has gradually grown from within outward, out of the necessities and character of the indweller, who is the only builder -- out of some unconscious truthfulness, and nobleness, without ever a thought for the appearance and whatever additional beauty of this kind is destined to be produced will be preceded by a like unconscious beauty of life.
我现在所看到的建筑学的美,我了解它是从内部向外面渐渐地生长出来的,是从那住在里面的人的需要和他的性格中生长出来的,住在里面的人是唯一的建筑师,——美来自他的不知不觉的真实感和崇高心灵,至于外表他一点儿没有想到;这样的美如果必然产生的话,那他先已不知不觉地有了生命之美。

This project studies the scale-dependent deformation behavior of the metal matrix composite, the void nucleation and void growth mechanisms at the micron/submicron scale. The main results are:(1) In prophase, growth and coalescence of the void embedded in the graded matrix are analyzed in detailed;(2) Based on the infinite solid model containing a micro-void, coupling effects of the void shape and the void size on the void growth are studied carefully, the results show that it seems to exist a critical equivalent void radius, which is associated with the material length. When radius of a microvoid is close to or smaller than the critical void radius, the micro-void growth rate is essentially eliminated;(3) The coupling effects of the particle shape and size on the mesoscopic stress fields within the particle and matrix are also investigated by introducing the conception of inclusion/matrix interfacial energy. The results show that the stress concentration factors within the particle and on the matrix/particle interface are also strongly size-dependent,so the void nucleation mechanism is size-dependent.(4) By employing a specific orthogonal curve coordinate frame and a 'kernel function' conception, a 'unified method'solving the spheriodal and spherical void problems is suggested; by this unified method, size-dependent plastic potentials of the porous materials containing the spheriodal or spherical voids are obtained, which extend the traditional Gurson model for the spherical void and GLD model for the spheriodal voids to the micron scale.(5) Based on the RVE model containing the spheriodal or spherical particles, the influences of the particle shape and size on the size-dependent mechanical behavior of metal matrix composite are studied.
中文摘要:本项目对金属基复合材料在微细观尺度下的尺度相关变形行为、孔洞形核及长大的机理和模型进行了研究,取得了如下主要结果:1)在前期研究中,探讨了基体的梯度分布对孔洞长大和聚合的影响;2)基于含孔洞的无限大体模型,探讨了孔洞形状和孔洞尺寸对其长大的耦合作用,结果表明:可能存在一个与材料特征长度相关的临界孔洞尺寸,当椭球孔洞的等效半径小于临界孔洞半径时,孔洞的长大受到明显抑制;3)通过引入基体/夹杂界面能的概念,分析了夹杂尺寸、夹杂形状对材料细观应力场的耦合影响,结果表明:颗粒内部和界面上的应力集中因子强烈地依赖于夹杂的尺寸和形状,因此,孔洞的形核机理是尺寸相关的;4)采用一种特殊的正交曲线坐标系和引入"核函数"的概念,"统一"地得到了含椭球和球形孔洞的材料的尺寸相关塑性势,它将传统的Gurson球形孔洞模型和GLD椭球孔洞模型推广到微尺度范围;5)基于含椭球和球形夹杂的体胞模型,初步研究了夹杂形状、夹杂尺寸对金属基复合材料尺寸相关力学行为的影响。

Wavelet multi-scale analysis is applied to the research on lunar gravity field and the explanation of lunar inner structure. In this paper, the nearside of the Moon with higher quality data is chosen as the test area, and free air gravity data from "Clementine" mission are used as original data to decompose gravity of some specific mare basins. With the results of numerical test, we also explain the hierarchical structure of the Moon, analyze the thickness of mare fillings and the Moho topography under mare basins, and verify the results by comparisons.
