查询词典 calculated

The background component must be calculated by integration of the product of aerodynamic force covariance and influence function, instead of mode superimposition, while the resonant component only consider the contribution of the 1st mode.

前者不能按振型分解法求解，而应通过对气动力协方差与影响函数乘积积分的方法来计算；后者可只考虑一阶振型的贡献，两者应按平方和开方的原则组合得到脉动风致响应的峰值。

A kind of visual prediction and analysis framework of the execution time of real-time software based on program flowchart is proposed in the paper. The key issues of implementing the framework are discussed in detail, including creating the mapping between intermediate code segment and statement line of source code, retrieving the time of any given program segment from the perspective of CPU cycles of goal machine instruct, calculating CPU cycles of statement lines of source code, point-to-point WCETC (worst case execution time calculated) analysis algorithm based on program flowchart, and transforming CPU cycle into physical time.

提出了一种基于控制流程图的程序执行时间的可视化分析框架，研究了中间代码段与源程序中语句的对应关系的自动分析、源程序语句行的CPU周期数的提取和计算方法、基于控制流程图的点到点最大时间分析算法和CPU周期的绝对时间估计方法。

It can get the three-dimensional profile of the object surface effectively. Because of the cragginess of the three-dimensional surface when sine grating is projected the image of the sine grating is modulated and the modulated image is taken by a CCD camera with an angel compared to projecting direction. After the phase shift measuring method, the phase is gotten. Because the phase is calculated by the phase shift measuring ranges from –π to +π it isn't continuous. The phase unwrapping is necessary to recover the continuous phase about the object shape.

这种方法采用结构光照明，将正弦光栅图像投影到被测物体表面，用与投影方向成一定角度的CCD摄像机获取受物体表面面形调制的变形光栅像，根据数字相移算法计算出相位分布，由于从相移计算的相位被截断在反三角函数的主值范围内，因而是不连续的，必须通过相位展开恢复出连续相位分布，由相位－高度关系最终求出物体轮廓的三维数据信息。

Since it is very difficult to established the model via ANSYS software, UG software is used to set up the model. In the fourth chapter, the bus body"sstructure are analyzed by ANSYS software. Three work situations of bus body are discussed, which are bend work situation, torsion work situation and crankle work situation. The stiffness and strength of bus body"s structure are calculated to guide the design of bus bodys structure.

由于使用ANSYS软件建模很不方便，本文使用UG软件建模，利用UG软件的图形数据转换接口，将作好的模型导入ANSYS中处理；第四章主要是介绍了如何使用ANSYS软件进行客车车身结构的分析，文中讨论了客车的三种使用工况，弯曲工况、扭转工况和弯扭工况，计算了客车车身的结构强度和刚度用于指导客车车身结构的设计。

The wall has no support during the construction stage and the calculationbased on the national standard GB 50018-2002 (Technical code of cold-formedthin-wall steel, structures) should be reliable and safe. The crankle destabilizationof the studs with cold-formed channel section should be taken into account whencalculating the load-carrying capacity. The warpings at both ends of the sectionshould be calculated without any constraint when converting the crankledestabilization into the slenderness rationλ_w.

墙体在施工阶段基本为无墙体支撑，此时，按现行国标《冷弯薄壁型钢结构技术规程》(GB 50018-2002)规定计算是可靠、偏安全的，在计算其承载能力时应考虑单轴对称冷弯卷边槽钢截面立柱弯扭失稳，在计算立柱弯扭失稳换算长细比λ_w时，截面两端翘曲宜按不受到约束条件计算。

However, perfect agreement of ages between structures (i.e., scales and otoliths) did not occur. Crappie length at age should be back-calculated using otoliths when more precise age estimates are needed and with scales when fish are too few to be killed.

因此，对于逆推计算的研究，没有确定耳石和鳞片哪个是完美的，但是在较少的样本的前提下，用耳石来对灰刺盖鱼的体长与年龄比鳞片精确一些。

We compared back-calculated lengths of crappie (Poinoxis spp.) scales and sagittal otoliths from seven Midwestern lakes using linear regression.

利用来自美国中西部七个湖泊的样品，我们利用回归分析比较了翻车鱼长度、鳞片和矢耳石。

How will my credit card balance be calculated?

College courses are offered at a certain cost, which is calculated on a credit hour basis.

某学院课程费用，这是一个学分计算基础。

The results indicate that intelligent is correlated with the double loop whorl, radial, simple creese hand, the third and fourth interdigital area pattern I3 and I4. The regression equations for predicting intelligent and radial, intelligent and I3, intelligent and I4 were calculated according to above results.

但是，多数学者所选用的实验对象为成人或优秀运动员，与早期实际选材相脱节，加之学者们的研究结果在某些指标上表现不尽相同和研究的样本量较小，误差较大等因素，使皮纹选材的理论体系尚不够完善。
