查询词典 irreversible process

It is undeniable that in the past have experienced property management low technological level and low level of management, the development of low-life treatment process; It is undeniable that today's property management in some areas remains "three low" position; However, with the property management companies to increase the intensity of support, property management and the sound system, raising the level of real estate development, It was an improved economic situation and changes in consumer values, property management and low technology content, the low level of management, the treatment of low-life into high-tech and high-level management, high-life treatment, is an irreversible trend of social development; property management become enviable career, will also be close at hand.

不可否认，过去物业管理曾经经历过低技术含量、低管理水平、低生活待遇的发展过程；也不可否认，今天物业管理在一些地区仍然处于"三低"的境地；然而，随着政府对物业管理企业扶持力度的加大，物业管理法规制度的健全，房地产开发水平的提高，人们经济状况的改善和消费观念的改变，物业管理的低技术含量、低管理水平、低生活待遇变为高技术含量、高管理水平、高生活待遇，将是不可逆转的社会发展趋势；物业管理成为令人羡慕的职业，也将为期不远。

The main results of the investigation are as following:(1) Some important criteria for the design of multi-layer structure are acquired: the ratio of the layer thickness to the contact diameter should be controlled to a value about 0.8; increasing the number of the gradient layers and elasticity modulus of the top layer would benefit to the yield strength and the stress status at the interface.（2）By means of molecular dynamics simulations for a indentation and sliding process, it is discovered that dislocations of 45 direction to the surface occur in the surfaces layer, which is correspond to the direction of the plastic flows observed in the macroscopic continuous medium. The irreversible deformation caused by the dislocation and the atom piles at the surface are responsible for the irreversibility of the force response. They are also the main factors for the friction generation. The temperature and the indentation velocity have significant effects on the deformation behaviors of the material of the surface layer. The yield strength would increase obviously if the indentation velocity is greater than 10 m/s.（3）A method to evaluate the fracture toughness of coating by estimating the crack-density functionβof a Wicker''s indentation was proposed. Meanwhile a new surface treatment technology was developed using non-equilibrium plasma.（4）A MD-FE hybrid method and corresponding software was developed to analysis the tribological behaviors for multiplayer system.

研究主要内容和结果有：（1）得到指导梯度膜设计的几个准则：控制膜层厚度与接触半径比在0.8左右为宜；适当增加梯度层层数和顶层弹性模量，有利于提高抗屈服能力和改善界面处的应力状态；（2）通过对嵌入和滑动摩擦过程的分子动力学模拟，发现表层产生一个与宏观连续介质的塑性流动方向观测一致的45 方向位错；位错造成的不可逆变形和表面的原子堆积，是力的响应不可逆性的原因，也是构成摩擦力的主要因素；温度和嵌入速度对材料变形特性有显著的影响，当嵌入速度大于10 m/s时，屈服强度明显增加；（3）提出压痕裂纹密度系数β半定量判定膜层断裂韧性的方法；并开发出表面强化新工艺；（4）开发出分析表面摩擦学特性的MD-FE复合模拟方法和相应模拟软件。

In the real world, however, all real thermodynamic processes are irreversible since the rate of exchange between the system and the environment is not infinitesimally small, the system does not maintain internal equilibrium, an the process duration is finite.

然而在现实中，由于系统和环境之间的热交换速率不可能无限小，系统不可能保持内平衡，且过程经历的时间是有限的，因此实际热力过程都是不可逆的。

The results show that the experimental results are in good agreement with the values of viscosity in a part of temperature range that has been reported, with the relative error of less than 2.5%; In the process of ascent and descent temperature, the irreversible phenomenon of the curve of viscosity versus temperature V presents interzone characteristic, and the break of viscosity at critical temperature reflects jump change of melt structural information; It is one to one correspondence between viscosity and atomic size, and this relation is consistent with the Hall-Petch formula in expression way.

结果表明：实验结果与已报道的部分温度区间内的黏度值基本一致，相对误差低于2.5％；升温和降温过程中，黏度－温度关系曲线V的不可逆现象具有区间特征，临界温度时黏度的突变反映出熔体结构信息的跳跃变化；黏度与原子集团尺寸之间存在一一对应关系，该关系在表达上符合Hall-Petch公式。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.
