  program reliability
     By using these rules and factoring formula, an efficient algorithm was proposed to evaluate the distributed program reliability (DPR) of distributed computing networks with imperfect nodes. The time complexity of the algorithm is O(N·(V+E)), where N is the total number of the nodes in the generated tree, V and E are the node and link number of the network, respectively. The DPRs of different networks were evaluated by computer experiments on Pentium 120 PC.
     提出了几个保持可靠性不变的缩减,结合这些缩减,利用因子分解公式建立了一个计算具有不可靠结点的分布式计算网络分布程序可靠性的有效算法,算法的时间复杂性是O(N·(V+E)),并对一些网络在Pentium 120 计算机上作了计算,结果显示用本文算法计算DPR所产生的N和所用时间比其它算法的要小得多。

One way to improve the reliability of the computer programmes is to develop an effective programme testing system. With the emergence of software packages in our country, the old testing instruments are no longer able to fulfil the new requirements for their testing.

One way to improve the reliability of the computer programmes is to develop an effective programme testing system. With the emergence of software packages in our country, the old testing instruments are no longer able to fulfil the new requirements for their testing. Therefore, it is necessary to design a new resting system. In this article, principles for desgning the new testing system are suggested; and furthermore, the way to construct a system according to the above-mentioned principles is elaborated. Examples are given, to show the application of the system. Asystem thus designed is flexble and convenient to use, and also is effective in speeding up the programme testing and in improving reliability.

发展强有力的程序测试系统,是提高程序可靠性的有效手段。但当前由于国内软件包的问世,在测试范围、测试要求和测试方法等方面,都提出了新的要求,原有的一般程序测试工具已不能独立地、完整地完成测试任务。因此,就提出了设计新的测试系统的要求。本文主要是根据软件包测试的新要求,提出了设计新的测试系统的一些准则。在此基础上,进一步阐明如何根据这些准则,来组成一个测试系统;并以实例来说明这种系统的使用对加速程序测试和提高其可靠性是有效的;同时,使用也很方便。

A complete automatic program for fission products Ge(Li) Gamma-ray spectra

本文提出一个裂变产物 Ge(Li)γ能谱自动分析程序——GSAP,并简要地介绍该程序的计算方法。GSAP使用带适当自变量约束的改进 Levenberg 算法来解峰的最小二乘拟合问题,最多能分析8重峰。GSAP选取不对称高斯分布加上二次本底作为拟合函数,一般给出较好的拟合优度。本文介绍了用来证明程序可靠性和精度的各种实验检定。GSAP在裂变产额测定工作中得到了满意的结果。GSAP实际上是一个通用程序,它可以用来分析其它方面实验的Ge(Li)γ能谱。

Up to now, There are still no accurate and reliable methods for computing The stress field of a shrouded air-cooled turbine biade, becauze the cooled blade with a complex configuration is worked under high temperature and large centrifugal Loads, moreover, the distribution of aerodynamic loads is also rather non-uniform. Usually, the practical problems are dealed with by means of experiments or statistics.With attempt to solve these problems, we use high order 3-D isoparametric elements to describe the complex configuration of blades. In order to deal with high order linear system of equations, we have used the frontal method which is highly accurate and efficient in saving main memory space. We also used the bicnbic Coons interpolation function to fit the space curved surface. At the same time we have compared the results with those of experiments and analytic solutions,an dproved that our method and program are reliable.This method is very well to fit various blades, such as a solid or hollow (i.e, air-cooled) blades, a blade with or without a shrouded,with or without a shank root,with or without high temperature.

带冠的高温空心冷却叶片,由于它的形状复杂,工作时所承受的离心力大,温度高,气动力分布极不均匀,因此,到目前为止,尚未见到准确可靠的计算方法,一般只能靠实验或统计的方式来解决生产使用中出现的问题。 为试图解决此一问题,我们采用高阶的三维等参元素来离散复杂的叶片形状,用节省内存空间而精度又高的波前法来求解此特大型方程组,用高阶双三次Coons样条插值函数来拟合叶型的空间曲面。为验证本方法和程序的可靠性,计算了各种例题,做了真实叶片的高速旋转实验,它们都证明了本方法是可靠的,计算精度是满意的。 本方法的适应性也较强,它可以计算实心和空心的、带冠的和不带冠的、伸根的或非伸根的、高温或常温的各种类型叶片。
