论经理人员工作效益的滞后性

效益滞后是经理人员工作的基本性质，文章以信息经济学为理论基础，并采用信息论的方法对经理人员工作效益滞后性的内在原因和机制进行了深入的探讨，然后用控制论的方法对决策滞后系统建模，并作进一步分析。     

Zur Reaktion eines Bis(amino)germylens mit Germaniumaziden: Abfangreaktionen von instabilen Germa-Iminen

Reaction of a Cyclic Bis(amino)germylene with Germaniumazides: Trapping-Reactions of Unstable Germa-Imines . The cyclic bis(amino)germylene 1 reacts with different germaniumazides of the type Me₂Si(NtBu)₂Ge(R)N₃ (R = Me ( 2 ), tBu ( 3 ), N(SiMe₃)₂ ( 4 ), R = N₃ ( 5 )). With the exception of 4 all azides lose dinitrogen when treated with 1 and the Ge^II center coordinates the α-nitrogen of the azide group. It seems to be reasonable to assume a transient germaimine (nitride) which is trapped by further reaction with the azide molecules 2 and 5 or by reaction with the solvent pyridine ( 3 ). In the case of 2 the germatetrazole [Me₂Si(NtBu)₂]GeN₄[Ge(NtBu)₂SiMe₂]₂ ( 6 ) is formed, the tetrazole nitrogens being exclusively substituted by germanium atoms (point symmetry of the molecule C_s(m)). When 1 is treated with 5 a tris(germa)amine [Me₂Si(NtBu)₂Ge(N₃)]₃N ( 8 ) is formed, which has an azide group attached to each Ge-atom. X-ray analysis reveals that the nine nitrogen atoms of the azide groups are coplanar with the trigonal planar Ge₃N moiety (crystallographic symmetry: 3/m). The reaction of 1 with 3 is very surprising: the pyridine in the product Me₂Si(NtBu)₂Ge(C₅H₄N)? N(H)Ge(tBu)(NtBu)₂SiMe₂ ( 7 ) is bonded via an α-carbon atom while the remaining hydrogen has added to the nitride-nitrogen. 6 crystallizes in the monoclinic system space group C2/m, a = 24.306(9), b = 10.933(6), c = 19.420(9) Å, β = 91.81(2)° and Z = 4. 7 crystallizes in the hexagonal system space group P6₃/m with a = b = 16.73(1), c = 11.006(8) Å, γ = 120° and Z = 2, and 8 crystallizes in the monoclinic system space group P2₁/n, a = 11.341(6), b = 26.086(9), c = 13.244(7) Å, β = 98. I2(2)° mit Z = 4.     

"无乐之乐,乐之至也"--陶渊明"性不解音"解读

史载陶渊明"性不解音",其实陶渊明对音乐的深刻理解是不拘泥于具体的曲调、音符,而只寻音乐的真谛的.他去掉琴的弦、徵,手抚素琴,独与宇宙精神相往来,追求的正是"乐之至"的"无乐之乐".     

醉酒终老——试析阮籍的狂放行为

遵循儒家"善"和道家"真"的原则,具有洁癣精神的阮籍选择消极对抗现实和统治者的生活方式, 在打破传统的过程中也使自己孤独无助,最后不得不选择"醉"作为容身之地,这是阮籍必然走向的悲剧。     

目前的离奇 心中的芜杂--《朝花夕拾》中鬼魅世界之探究

《朝花夕拾》不仅记载了鲁迅先生的绍兴生活及南京读书,日本留学,回国工作的经历,而且更深刻地反映了他对当时社会现实的认识,表现了他自我内心世界的情态,展示了对故乡风情民俗的留恋,文集中所突出描绘的独特的鬼魅世界,以及亲友亡故之往事,既是现实社会的观照,也是鲁迅先生暮年心态的折射,不家乡土风习的撷趣。

Differences of Convex Compact Sets in the Space of Directed Sets. Part I: The Space of Directed Sets

A normed and partially ordered vector space of so-called directed sets is constructed, in which the convex cone of all nonempty convex compact sets in R ⁿ is embedded by a positively linear, order preserving and isometric embedding (with respect to a new metric stronger than the Hausdorff metric and equivalent to the Demyanov one). This space is a Banach and a Riesz space for all dimensions and a Banach lattice for n=1. The directed sets in R ⁿ are parametrized by normal directions and defined recursively with respect to the dimension n by the help of a support function and directed supporting faces of lower dimension prescribing the boundary. The operations (addition, subtraction, scalar multiplication) are defined by acting separately on the support function and recursively on the directed supporting faces. Generalized intervals introduced by Kaucher form the basis of this recursive approach. Visualizations of directed sets will be presented in the second part of the paper.     

对三峡江南入蜀古道的有关认识

长江三峡南岸入蜀古道，是除三峡水道外又一入蜀的重要陆路通道。此道东起湖北宜昌市江南点军区姜诗溪口，西至利川市谋道苏拉口，全长500公里，东连着丰饶的荆楚大地，西可通往“天府之国”的川西平原，20世纪70年代修建的318国道路线大致上走的就是三峡南岸的西行人蜀古道。古道始筑于商周时期，沿用于秦汉以后一直到现在。历史上每到朝代更替之际，它都被用作军事通道，而太平盛世之时，它又成为社会经济发展中的交通生命线。在古道上遗留下来的一些遗址、墓葬、窖藏、桥梁、石碑、石板路等各类古文化遗迹向我们叙述着昔日商旅、驿差、军队、部族人群等在古道上往来奔波的繁忙图景。     

清代安康张鹏飞刻书考略

张鹏飞是清代陕西安康著名教育家、出版家,他曾以＂来鹿堂＂之名刊刻多种书籍。现今可考的张鹏飞的＂来鹿堂＂刻书有近四十余部,他刊刻的书具有实用性、支持家乡文教事业的特点,究其原因与其生于清未的时代有极大的关联。
