| 5. | Due to the property of the solution of this problem , we introduce a semi - circular artificial boundary in the unbounded physical domain and design high order artificial boundary conditions on it
由于该问题解的性质，我们在无界物理区域上建立半圆形的人工边界并在其上设计出了高精度的整体型人工边界条件。 |
| 6. | The design problem can be divided into four domains : the customer domain , the functional domain , the physical domain and process domain in axiomatic design . the two axioms are applied to evaluate the proposed design
公理设计理论将设计问题可分为4个设计域：用户域、功能域、结构域和工艺域，以两条设计公理作为评判设计优劣的依据。 |
| 7. | Namely for the given problem we introduce some suitable artificial boundaries to divide the unbounded physical domain into the bounded computational domain and unbounded part and set up high order artificial boundary conditions on the given artificial boundaries

| 8. | It provisioning issues can include things that are in the digital domain - like giving access to computer systems , files , directories , or buildings - as well as the physical domain - like obtaining laptops , cell phones , or seating space for new employees
It配置问题既包括数字领域的问题，如授予计算机系统、文件、目录或大楼的访问权；也包括物理领域的问题，如为新员工申请膝上型电脑、蜂窝电话或者办公桌椅。 |
| 9. | Hence this method can improve accuracy and efficiency of the calculation . c . based on these work upwards , an adaptively wavelet precise time - invariant integration method was proposed in this paper . in this method , an adaptive multilevel interpolation wavelet collocation method for partial difference equations ( pdes ) was conducted , in which the time complexity is less than oleg v ' s method , and then the adaptive precise integration method was combined with , so that in this method the adaptively discretes both in time domain and physical domain were realized
该方法将外推法引入求解结构动力方程的精细时程积分法中，从而使该方法在求解非线性动力方程中可以自适应选取时间步长；需要指出的是，由于考虑了矩阵指数精细算法和外推法算法在时间离散方法上的一致性，在外推过程中，计算工作量基本没有增加；因此，两种方法的结合有效提高了算法的效率和精度。 |
| 10. | On the basis of considerationbs of the physical domain , the characteristics of the tides and sediment distribution patterns of the bohai strait , a 2 - d horizontal model has been designed to study the long - term transport of sediment and accumulation over the bohai strait region . the model output is consistant with field observations , and can be used to explain patterns of long - tern transport and deposition of sediment in the study area
本文根据渤海海峡空间尺度的大小、潮流特征和沉积物的性质特征，构造了一个垂向二维沉积物输运数值模型，结合已经取得的有关潮流和沉积物的各种相关资料，进行了沉积物长期输运的数值摸拟，所得结果符合实测的结果，揭示了本区沉积物长期输运和沉积的分布格局。 |
