Examples
- In the paper , concrete is taken as three phases composites consisting of aggregate matrix and bond between matrix and aggregate on meso - level . using monte - carlo method , the positions of the aggregate structures are generated . mesh is projected on them , different material properties are assigned to the respective elements according to element location in individual phase
应用蒙特卡罗方法，在平面上随机地确定骨料的位置，产生出随机骨料结构，并进行网格自动剖分，根据其空间位置确定各单元所属的相，分配相应的材料特性给相应的单元，用以代表骨料、砂浆及两者之间的过渡层。 - At first , ploygon aggregate structure of concrete is randomly generated in two - dimensional plane with monte carlo method on the meso - level . then , the growth process of a crack of concrete 3 - point bending beam specimen is analyzed by fem , according to the criterion of maximum circumferential tensile stress . and the path of crack to spread in mortar , aggregate and interfaces of them is gained by the ultimate fracture criteria in construction standard that the width of crack should not be more than 0 . 2mm
首先，在细观层次上，根据蒙特卡罗随机抽样原理，在二维平面上建立了混凝土多边形随机骨料结构模型，然后采用有限元计算方法，根据最大周向正应力准则，对三点弯曲梁构件进行了开裂过程的模拟，并以建筑规范中构件裂缝小于0 . 2mm的要求为最终破坏标准，得出了裂纹在基质、骨料及界面的扩展路径。 - A new interface - perturbation model of solid - state displacement reactions ternary system is suggested and the interface - stability criterion is derived in the form of chemical potential if the chemical potential of rate - control - element at frontier of tiny perturbative zone goes up less than 20 . 7 % , linear interface will grow up stablly and form layered structure ; if it goes up more than 20 . 7 % , linear interface is not stable and will form aggregate structure
通过建立界面扰动模型，推导了三元固态置换反应系界面稳定性的化学势梯度判据。结果表明：如果扰动微区前沿速率控制元素的化学势梯度升高小于20 . 7 ，平面界面稳定长大，将形成层状结构；若大于20 . 7 ，平面界面不稳定长大，将形成束集型结构。 - Ploughing deeper and corn residues might promote formation of soil aggregated structure , decrease soil bulk density , relax solum , decrease soil porosity , raise soil permeability , improve soil structure and holding - water capability , create better soil biology condition for growth of crop , and coordinate water , fertilizer , air and heat etc . to prevent the fertility deterioration of the corn belt phaeozem and ameliorate soil , it is need to reform tillage and fertilizer application for the corn belt phaeozem in the central part of jilin
针对吉林玉米带黑土土壤退化现象，从黑土玉米的耕作制和施肥制的改革入手，并结合农村现有机械和技术水平，采用玉米“轻主重辅”三三耕作制和玉米“一稳二减三补”施肥技术，提出吉林玉米带黑土土壤调控技术体系。 - 2 . the structure of purple soil is meliorated by sabaigrass . when contrast to bare land treatment and natural wild grassland treatment we knew that sabaigrass treatment and grass tree solid plating treatment reduced soil bulk density , enhanced soil capillary porosity , non - capillary porosity and porosity ratio , decreased soil sand grain content , enhanced soil clay grain and silt grain content so as to reduced the dispersal degree of soil , improved the aggregate capacity of soil , increased the amount of soil aggregate structure , meliorated the water permeability of soil , accelerated the form of good soil structure
龙须草能改善紫色土的土壤结构龙须草纯种植被和林草立体种植植被能不同程度地降低土壤容重，减少土壤砂粒含量，增加土壤的毛管孔隙度、非毛管孔隙度和孔隙比，以及增加粉粒含量，从而降低土壤分散度，提高土壤团聚性，增加土壤团粒结构数量，改善土壤的透水性，促进良好土壤结构的形成，最终提高土壤的蓄水保肥性能，增强土壤的抗蚀性和抗冲性。
