There are a lot of analysis models,index and data involved in management accounting,which is used by people without deliberations,and considered as absolute correctness However,management accounting has not been developed so consummately In fact,there still remain many questions deserving further study and discussion For example,some methods are not actual,while some don't take cost into consideration at all More attention should be paid, and more efforts are needed to make management accounting mor...

管理会计学科知识中涉及到大量的分析模型和数据指标，在现实生活中往往被人们不加推敲地生搬硬套，视其为当然的权威、绝对地正确，使管理会计的学习应用趋于教条化。而实际上，管理会计还是一门发展并不十分成熟的学科，其中存在许多值得我们进一步研究和论证的问题。例如，有些方法已明显与现实脱节，有些方法还停留在以静止的观点看问题，有的不考虑管理会计这一信息系统中数据信息的取得成本，有的分析模型一味追求精确复杂反而失去了实际应用价值，有的分析方法干脆就不具备多少严谨性和可信性。本文针对以上问题进行了讨论，旨在抛砖引玉，使管理会计这一学科更加健全和完善。

Furthermore, the first-order optimality condition and its equivalent reformulations for generalized semi-infinite max-min programming with a non-compact set are presented using the lower-Hadamard directional derivative and subdifferential.2. Chapter 3 studies the gradient-type methods for unconstrained optimization problems. Section 1 proposes a new class of three-term memory gradient methods. The global convergence property of the method is established. Furthermore, in order to improve the convergence property of the method, a new class of memory gradient projection methods is presented with the property that the whole sequence of iterates converges to a solution to the problem under the conditions such as pseudo-convexity and continuous differentiability of objective function. In section 2, two new classes of methods, called gradient-type method with perturbations and hybrid projection method with perturbations, are proposed. In these methods, non-monotone line search technique is employed, which makes them easily executed in computer.

第3章研究了无约束优化问题的梯度型算法，第1节提出了一类新的三项记忆梯度算法，讨论了算法的全局收敛性，进一步提出了一类新的具有更好收敛性质的记忆梯度投影算法，并证明了该算法在函数伪凸的情况下具有整体收敛性，第2节在非单调步长搜索下提出了带扰动项的梯度型算法及其混合投影算法，这两类算法的一个重要特征就是步长采用线搜索确定而不象许多文献中那样要求步长趋于零，这样更容易在计算机上实现，在较弱的条件下证明了这些算法的全局收敛性，数值算例表明了算法的有效性。

For PDEs with small parameters, a scheme is AP if it possesses the discreteanalogy of the continuous asymptotic limit as the small parameter goes to zero.

对于含有小参数的偏微分方程，所谓一个算法是渐近保持的指的是，当相应的数值离散在小参数趋于零的时候，仍然是渐近极限的合理数值离散。

Results show that with the increase of the convergence angle,light field in biological tissues and the reflectance enhanced in the beginning,after reaching the peak value,its intensity decrease quickly and the position of its maximum deflects from central position.

结果表明：随着光源会聚角的增大，组织内光场分布和组织漫反射的分布趋于集中，当大于一特定角度之后，光场强度的分布区域迅速扩大，强度迅速下降，同时强度出现极大值的位置开始偏离中心位置。
