First, in the composite hypothesis testing, circular dispersion error which is more practicable than horizontal and vertical error is used to discuss some problems of the dispersion of impact points; and the critical area of decision in the dispersion problem is analyzed; the specific expression of Bayesian risk is worked out, which ameliorates the method that only can get the approximate solution by calculating numerical integration.

由此，本文主要应用Bayes方法对以下几方面进行了探讨：首先，在复杂假设下，本文利用圆散布误差这一精度指标对落点散布鉴定问题进行研究，它比以往所用的纵、横向偏差精度指标更具现实意义；分析了此鉴定问题的决策临界区域；给出其Bayes风险的具体表达式，对用数值积分进行近似求解的方法进行了改进；在此基础上，通过极小化试验的风险确定最优试验数n，并讨论了决策中犯两类错误的概率，给出了验前信息的表示。

Quot; Arista records heard these demos at the beginning of 1997, and Dido was invited to the Dorchester Hotel in London to meet Clive Davis.

接下来的两年中，蒂朵和无信念一起前往数十个国家巡回演出，经历了与以往身为古典乐团一员截然不同的日子。

In Chapter 2, one kind of rational cubic spline interpolation with linear denominator has been proposed, whose derivatives are replaced with accurate derivative values, difference quotient and arithmetic average difference quotientrespectively.

第二章给出了一类分母为线性的有理三次插值函数，当其导数值分别取为导数的精确值，一阶差商，以及算术均差商时，便得到三种插值格式，分别为给定导数值的有理三次插值函数，基于函数值的有理三次插值函数，以及基于算数均差商的有理三次插值函数。

Finite Element Method is an important means of engineering subject and has been proved to be a common method in many subjects. However, disadvantages still remained. During the structural analysis, large amount of high-order units were used in order to ensure the precision of arithmetic solution when using Finite Element Method to do discrete processing. This will cause high order of coefficient matrix of corresponding equation group.

有限元方法是工程学科的重要工具，被证明为在许多科学和工程领域中连续物理系统模拟的一种普遍方法，但缺点是随着工程结构分析问题越来越复杂，在结构分析中，为保证数值解的精度，在使用有限元方法离散处理时，往往要用大量的高阶单元将结构剖分得很密，这时相应的代数方程组的系数矩阵的阶数很高，即使用目前速度最快的串行机来进行求解，费时仍然太多且问题的规模受到内存容量的限制。

In this paper, a reliability analysis approach based on triangular fuzzy number arithmetic operations is proposed, and some examples using this approach are given.

提出了一种基于三角形模糊数算术运算的可靠性分析方法，并给出了应用该方法的一些例子。

New Year's Day, Spring Festival, Fool's Day, Labor Day, Children's Day, Army Day, Teacher's Day, National Day ...... Pipi are counting down to a few, but how many holidays a year.

元旦、春节、愚人节、劳动节、儿童节、建军节、教师节、国庆节……皮皮掰着指头都数不过来一年有多少个节日。

If an array has a run-time expression as its bounds, then it is a VLA.

如果一个数组以一个运行时表达式作为边界，那么它就是一个变长数组。

If an array has a constant expression [2] (an expression that can be evaluated at compile time) as its bounds or empty braces (only permitted in a few contexts), then the array is not a VLA and has the same semantics such arrays have always had in C.

如果一个数组以常量表达式[2]（能够在编译时求值的表达式）或是空括号作为边界，那么这个数组不是VLA并且跟一直在C中的数组拥有相同的语义。

The results show that the degassing efficiency increases with the residence time increasing;when other parameters are certain, the degassing efficiency increases with the number of arris and the concave depth increasing;the degassing efficiency decreases with the angle increasing.

结果表明：脱气效率随着滞留时间的增大而增大；当其他参数一定时，脱气效率随着棱数和凹入深度的增大而增大，随着角度的增大而减小。

The few particles of pigment that are perhaps remaining from the Romanesque polychrome of a wooden sculpture no more justify the removal of a fully preserved baroque polychrome than do the remains of a Roman ashlar stone wall justify demolition of an entire building that has evolved over the following centuries.

不必为了十一、二世纪罗马式彩绘木雕中一些残存颜料而除去同一件木雕上保存良好的巴洛克式彩绘层。但是，为了保存罗马时代精致的祭坛石墙，可以考虑毁去数世纪以来夹缠增建、而又坍塌的建筑物。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
