There was usually a decline in farm output in the first year or two after the establishment of a Red area, chiefly because landownership was not yet settled and the new economic order was not fully established during land redistribution, so that the peasants could not yet set their minds fully on production.

1〕农业生产在革命根据地建立的头一二年，往往有些下降，主要地是由于在分配土地期间，地权还没有确定，新的经济秩序还没有走上轨道，以致农民的生产情绪还有些波动。注意，注意力集中

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。

You are unable to concentrate on mundane matters and you may find yourself daydreaming.

你不能集中精力在平凡的事情上，你可能发现自己在白日做梦。

"Boys that did not receive the during the mid-1990s are now collecting in large numbers in secondary schools and colleges, and this provides a perfect breeding ground for the virus," Niall Davis, a urology research registrar, said in a news release. It's estimated that as many as 40 percent of males who develop mumps after puberty can suffer from orchitis.

"20世纪90年代中期没有接种 MMR 疫苗的男孩，目前大量地集中于中学或大学里，这为腮腺炎病毒提供了极为理想的滋生地，"泌尿学研究主任尼尔·戴维斯在一次新闻发布会中说，据估计，在青春期之后患有腮腺炎的男性中，有多达40%的人可能会患上睾丸炎。

On the base of these, the electron diffuse scattering, being highly intensive and confined in reciprocal space to a regular geometric surface exhibiting the translation symmetry of the b.

发现在各倒易截面中，电子漫散射强度集中分布在一较窄的带状规则几何图形上，并且，各几何图形同与之相应的对应于面心立方f.c.c。

However, the Chinese team is comparatively poor at making a place kick in this cup match. Except for Shao Jiayis direct placement, there are no other goals by place kicking. On the contrary, the opponents achieved 4 placement shots, which show that the Chinese team has some deficiencies and scatterbrained phenomenon with regard to the defensive placement shot aspect.

而中国队在本次杯赛上定位球得分相比之下较差，除了邵佳一的那记直接任意球之外，定位球无一入球，相反却让对手打入4个定位球，说明中国队在防守定位球方面存在缺陷和注意力不集中的现象。

For example their understanding of the phenomenon of self-induction is not deep, so questions are often wrong, then they put out the fault in this matter and important topics together in practice and reflection, I found to know but did not understand the physical laws, to find a general way to answer this problem, such as from where to start with, what are the formula and so on.

比如们对自感现象理解不深，做题常常出错，那么就把们在这个问题上出过错的和重要的题目集中起来，在练习和思考中，发现知道但是并没有理解的物理规律，找到解答这种问题的一般途径，如从什么地方下手，用什么公式等等。

However, it has a very small scale in manufacturing industry, a less inputs of funds and personnel in science and technology, and a lower level of technological innovation investment in China. It is concentrated territorially in Guangdong, Fujian, Jiangsu, Zhejiang, Shanghai, and so on. There are many problems in the process of its development, such as the smaller size of enterprises, the lower market share, the more irrational development of product structure, the slower product upgrading, and the more insufficient governmental fostering means and legal support.

然而，目前该产业在我国制造业中规模很小，科技经费和科技人员投入较少，科技创新投入水平较低，且在区域分布上主要集中于广东、福建、江苏、浙江、上海等省市，其发展中存在着企业规模小、市场占有率低、产品结构开发不合理、产品更新换代速度迟缓、缺乏政府性的培育手段和法律支持等问题。

It is hard to imagine a student focusing their energy on text book while other children are playing.
