The rhythmic proportion was an important precondition and foundation to the serialize rhythm and integral serialism later. The article analyzed Webern's two early compositions, the Six Orchestral Pieces, Op.6 (1909), and the Five Pieces for Orchestra, Op.10 (1913), both of them in the style of free atonality. From the relation principle of the rhythmic cell, the writer discussed Webern's way of organizing rhythm, technique of developing variate of rhythmic cell, as well as its score writing way, and summarized the Webern's early orchestral outputs rhythmic features and its impact on the rhythm style of the works in his later years.

文章以威伯恩早期自由无调性时期的两部管弦乐作品《六首管弦乐小品》Op.6和《五首管弦乐小品》Op.10为对象，从"节奏细胞"的形成以及关系原则着手进行剖析，挖掘、揭示作品中节奏的组织方式；并进一步用作品文本说明、论证节奏细胞的变值发展手法与节奏细胞的谱面组成方式；最后总结出威伯恩早期管弦乐作品中的节奏特征以及对作者晚期节奏风格产生的影响。

We first state general linear model, ridge-type estimator and general ridge-type estimator, and the constraint biased estimator. And then, we introduce some basic theory about matrix and some conclusion about the admissibility of estimator in Gauss-Markov model. In the third chapter, we discussion several equivalent characterization of the best linear unbiased estimation, we proved that admissible characterization of admissible of linear estimation is as conditional general ridge-type estimation in general linear model. A necessary and sufficient condition that homogeneous linear estimator is admissible estimator is obtained.

本文首先概述了一般线性模型，岭估计及约束岭估计的发展历史和研究现状，在第二章介绍了矩阵的一些基本知识和可容许性的一些基本结论，第三章讨论了一般线性模型最佳线性无偏估计的几个等价条件，以及线性估计的可容许性特征，得到了一般线性模型的可容许线性估计均具有条件广义岭估计的形式，给出了一个齐次线性估计为可容许估计的充分必要条件。

In section 4,we research the solvable groups of finite rank,and provethat the union set of all quasi-cyclic subgroups of G is a characteristic subgroup andthe Hirsch number hdoes not exceed n if G is a solvable group of rank n.Inparticular,for an arbitrary solvable torsion-free group G of rank n,we give theupper bound fof the derived length of G.

在第4节里，我们研究了有限秩的可解群，证明了这类群的所有拟循环子群构成它的一个特征子群，且对秩n的可解群G来说，其Hirsch数h≤n，另外，我们给出了秩n的无挠可解群的导出长度的一个上界。

Volcanic gas reservoirs of low permeability in the carboniferous of a basin are characterized by deep burial depth, complex genesis, many types, wide distribution and non-evident expressions in three-porosity log curves, as well as the variedvalues of density and compression wave of main four volcanic gas reservoirs (such as the basalt, andesite, dacite and rhyolite). So a number of effective methods based on three porosity log data cannot work in identifying the volcanic gas reservoirs of the carboniferous of the basin.

石炭系火山岩的低渗透气藏具有的埋藏深、成因复杂、类型多、分布广、三孔隙度曲线响应特征不明显等特点，并且主要的四种火山岩气藏：玄武岩、安山岩、英安岩、流纹岩的密度和纵波时差测井值差别较大，因此使基于三孔隙度测井资料的一系列识别气层的有效方法在该盆地石炭系火山岩气层的识别中无明显效果。

Through establishing the functional of the source pulse which is based on the concept of "usable energy" in the received pulse and then extremizing the functional by means of the calculus of variations, the mathematical models of the optimized source pulse waveforms are shown to be associated with the eigenfunctions of a homogeneous Fredholm linear integral equation of the second kind. An efficient algorithm is developed for numerically solving the integral equation models.

会计的信誉已受到了严重损害，诚信，成了全社会面临的话题。一旦诚信成为会计领域的稀缺资源，则真实性、可靠性、公允性等财务信息的质量特征会演变为一种幻觉，假账更会像脱僵野马一样狂放无羁。呼唤诚信的回归，与其说是寻找失去的道德家园，毋宁说是进行一场痛彻骨髓的精神救赎。面临严重的信任危机，如何重塑会计的诚信，成为时下会计界所有人士亟需解决的问题。本文就会计诚信问题谈点自己的看法，以期抛砖引玉。
