长大

Actually they were just anxious to grow up; to imitate adults is absolutely an anxiousness to grow up.

其实他们还是急于长大，模仿大人当然是"急于长大"。

However, we realized someday that adulthood means more than appetence. It implies courage, liability, adamancy and sacrifice when necessary. We are still kids before life. In fact, we are far from growing up because we do not understand how to read love and being loved yet.

曾经在某一瞬间，我们都以为自己长大了，但是有一天，我们终于发现，长大的含义除了欲望，还有勇气、责任、坚强以及某种必须的牺牲，在生活面前我们还都是孩子，其实我们从未长大，还不懂爱和被爱。

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。

In order to improve present Monte Carlo methods, method changing the node to optimistical orientation corresponding to the system having the lowest energy was proposed, which ensures the grain boundary moving to its curvature center. The new method avoided re-nucleation, and increased simulation efficiency, and made the simulation process more approaching the physics foundation of grain growth. The results show that the grain growth exponent, n=0.478, is close to its theoretic value, and the topological structure accorded with the normal grain growth of the real material.

简要回顾了晶粒长大理论并分析了现有Monte Carlo模拟方法的不足，提出了一个"择优转换"方法，确保节点转换时晶界向其曲率中心移动，以致模拟过程更接近物理基础，避免了重新形核的发生，使模拟效率大大提高，模拟的晶粒长大指数达到0.478，已接近理论值，组织形貌和实际材料正常晶粒长大组织基本一致。

It is because of the small rate constant of crystal growth that the crystal growth is irreversible reaction when nuclei appear in the supersaturation solution.

原因是晶粒长大的速率常数很小，过饱和溶液中一旦有晶核生成，就开始进入不可逆的晶粒长大过程，即溶液中晶粒长大的条件是有晶核的存在，而温度、阻垢剂对之影响甚微。

The welding nugget happened to dynamically recrystallize and the refined crystal grains were obtained and the majority of Mg_2Si particles dissoluted due to the intensive mechanical stir and higher high temperature. In the thermal-mechanical affect zone that was heated under the recrystallized temperature, the crystal grains were elongated due to the mechanical stir and Mg_2Si particles partly dissoluted and the others grew. In the heat affect heat without the mechanical stir, to some extent, both of the crystal grains and the majority of Mg_2Si particles grew.

焊核区受到强烈机械搅拌作用和加热到较高的温度发生动态再结晶，得到细小等轴晶组织，Mg_2Si相以溶解为主；热机影响区加热温度低于再结晶温度，在机械搅拌作用下晶粒由于塑性变形而伸长，Mg_2Si相部分溶解，部分长大；热影响区仅受加热影响，晶粒有一定程度长大，Mg_2Si相以长大为主。

The results show that the cavity nucleates while the twin-roll-cast AZ31 alloy sheet deforms, and the cavity starts on the tri-grain boundary. The continuously growth and coalescence of the cavities induce the material fracture. The cavities grow directionally and prefer to grow along axis perpendicular to the loading axis.

结果表明：镁合金板材热变形过程中，空洞首先在晶界尤其是在三叉交界处形核，随后不断长大和聚合，导致材料断裂；空洞的长大具有方向选择性，与拉伸轴方向垂直的空洞容易长大。

Sometimes I just feel like, quitting I still might Why do I put upthis fight, why do I still write Sometimes it's hard enough just dealin wit real life Sometimes I wanna jump on stage and just kill mics And show these people what my level of skills like But I'm still white, sometimes I just hate life Something ain't right, hit the brake lights Case of the stage fright, drawin a blank light Da-duh-duh-da-da, it ain't my fault Great big eyeballs, my insides crawl And I clam up, I just slam shut I just can't do it, my whole manhoods Just been stripped, I have just been vicked So i must then get, off this bus then split Man fuck this shit yo, I'm going the fuck home World on my shoulders as I run back to this 8 mile road I'm a man, I'ma make a new plan Time for me to just stand up, and travel new land Time for me to just take matters into my own hands Once I'm over these tracks man I'ma never look back (8 mile road) And I'm gone, I know right where I'm going Sorry mama I'm grown, I must travel alone Ain't gunna follow these footsteps, I'm making my own Only way I know how to escape from this 8 mile road I'm walking these train tracks, tryin to regain back the spirit I had fore I go back to the same crap To the same plant, in the same pants Tryin to chase rap, gotta move ASAP And get a new plan, mommas got a new mam Poor little baby sister, she don't understand Sits in front of the T.V, buries her nose in the pad And just colors until the crayon gets dull in her hand While she colors her big brother, her mother and dad Ain't no tellin what really goes on in her little head Wish I could be the daddy that neither one of us had But I keep runnin from something I never wanted so bad!

Good agreements were attained between measurements in SEM and modeling by DICTRA. Ostwald ripening should be used for the coarsening calculation of Laves phase in P92 steels for time longer than 20 000 h and 50 000 h at 650℃ and 600℃, respectively.

采用热力学计算程序DICTRA进行数值模拟，结果表明，所采用的Laves相长大模型能够很好地模拟Laves相的长大规律，但长时间(650℃、20 000 h和600℃、50 000 h)后应采用奥斯特瓦尔德长大规律来分析Laves相。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。
