受到约束

• View , while helpful , is rather limited in functionality , and it admittedly makes assumptions about the directory structure that some may find constraining
  视图（尽管有帮助）在功能上相当有限，无可否认，它对目录结构做了假设，这使得有些人觉得受到约束。
• In engineering , structures may expand or contract while they are heated or cooled . at that time , if the structures are restrained the thermal stresses will happen
  在工程应用中，由于温度场的变化，使结构产生膨胀或收缩，当结构受到约束时，产生温度应力。
• The development of finance must be restrained , which is carried out by the capacity or potential of economy - this is the financial boundary as put forward in this paper
  金融的发展必须受到约束，约束的条件就是经济发展的可能性，或者经济的潜力，这就是论文所指出的金融边界。
• A cer defines an area in which the common language runtime is constrained from throwing out - of - band exceptions that would prevent the code in the area from executing in its entirety
  Cer定义一个区域，在该区域中公共语言运行库( clr )会受到约束，不能引发可使区域中的代码无法完全执行的带外异常。
• But be the concrete to transform the stipulation ( repress , bar ) function , then want the companion to living to pull in response to the dint with pull to adapt to changes
  混凝土随着温度、湿度的变化要伴生胀缩变形。而当混凝土的收缩变形受到约束(抑制、阻碍)作用时，则要伴生拉应力和拉应变。
• Although ws - i is still working on finalizing the basic security profile , there is one aspect of the bsp that needed to be further constrained - the choice of encryption algorithm
  尽管ws - i仍然在从事于确定基础安全概要的最终形式，基本安全概要的其中一个方面需要进一步受到约束密码运算法则的选择。
• On one hand , the stress in mass concrete is caused because of the difference between internal temperature and external one . on the other hand , with the concrete solidifying , the tensile stress will appear due to concrete ' s shrinkage restrained by base rock
  大体积混凝土一方面由于内外温差而产生应力，另一方面，由于混凝土的凝固，收缩变形受到约束，混凝土会产生拉应力，一旦温差引起的应力和收缩变形引起的应力超过同龄期混凝土的极限抗拉强度，混凝土就会产生裂缝。
• All concrete structures are exposed to volume changes caused by hydration reactions in the early age . if the volume changes are restrained , stresses is generated which will cause cracking when it overcomes the tensile strength . as the mechanical properties of early age concrete vary with time , especially the creep degree depends on the time elapsed and the time at loading , to calculate the stress of concrete structure is a complex nonlinear problem . the finite element method ( fem ) can take account of the evolution of the stiffness properties , the development of thermal strain , creep , shrinkage and so on . in this paper , a general approach for numerically simulating this type of behaviour is presented firstly . then , how to solve this problem is introduced by the general finite element software ansys using the initial stress method . finally , a detailed description of an example calculation that demonstrates the potential of the numerical simulation strategy follows
  早期混凝土由于水化反应都会产生体积变化.如果体积变形受到约束就会产生应力,一旦超过混凝土的抗拉强度就会产生裂缝.由于早期混凝土的力学性能是随时间变化的,特别是徐变,它不仅与加载时间有关而且同时随龄期而变化,因此计算早期混凝土结构应力是较为复杂的问题.有限单元法不仅可以考虑混凝土刚度的变化,而且可以考虑温度、徐变、收缩等因素.本文利用初应力法对通用有限元软件ansys进行了二次开发,通过工程实例计算了高层建筑地下室侧墙早期混凝土应力的变化过程,并提出了相应的抗裂措施
