This paper contains two parts: an exact solution of vibration modes and transverse cigenfrequencies of conical shells is studied first, and then is presented a simplified method or computation for practical uses.Donnell type differential equations with variable coefficients are used. Under the assumption of neglecting the tangential components (tangential to median surface) of inertia force, and taking the solution as the following type:an uncoupled equation for solving functions of transverse vibration modes is deduced after using some differentia! operators, as the following:Other two equations, showing the relations between U(x) and W(x), and V(x) and W (x) respectively areliquation (2; gives power-series solutions for W(x), liaving a unperiodic osoillating character and rapidly increasing amplitude, so are the solutions of U(x) and V(x). Unfortunately, the convergence of this series solution is poor, so that limits its practical applications.In order to reduce the computing works, a simplified method is recommended. The physical conception of this method is illustrated as following: Cutting one element from the shell arbitrarily, we shall use a physical model to represent this element (see fig- 2) When vibrating, the elastic restoring effects due to membrane extensional forces and bending (and twisting) moments are looked as two springs in parallel as fig. 2, while the element is the mass m. Then this element of shell is equivalent to the parallel springs system with single degree of freedom, and the whole shell can be represented by the sum of infinite systems of this single type, where the stiffness of springs are functions of the co-ordinates. It is known, that the eigenfrequency of the parallel springs system isThis relation shows us to calculate the eigenfrequencies of conical and cylindrical shells(and other shells) by superposing the results which are obtained from membrane theoryand pure bending theory respectively, i.e., the result w1 is solved by using the following equation :together with cqu. (3) and (4), while the result w2 is obtained by solving the equation:Ihe answer can then be calculated, according the relation w2 = w12 + w22.The analytical method presented in this paper can be used for shells with arbitrary conical angle a and various boundary conditions (the conditions at the vertex point of complete conical shell is discussed).

本文首先用分析方法求出了圆錐壳的振型函数和横向振动固有频率的精确解,然后为了实际应用的目的,建議了一种簡化計算方法。 文内采用了扁壳理論形式或称Donnell形式的运动微分方程組;在忽略切向慣性力分量的假设下导出了以一个横向位移函数表示的独立方程,从而得到了振型函数的冪級数解答,由此可看出圆錐壳的振型函数具有非周期性和幅度递增很快的振蕩特性。 鉴于上述运算过于繁重,故再提出一种簡化計算方案,其物理概念为:給壳体上任一元素建立一物理模型如图2所示,将振动时产生的薄膜张力和抗弯(扭)力矩的弹性恢复作用分別看作二个弹簧k_1和k_2,壳体元素即图中质量m,这样就得到一个并联弹簧的单自由度系統;于是整个壳体就相当于由无限多个这种单自由度系統組成,而弹簧刚度則是坐标的函数。由于該模型的固有频率可由迭加关系——ω~2=k_1/m+k_2/m=ω_1~2+ω_2~2計算,故可推出,錐壳振动可以按无矩理論和純力矩理論分别計算出ω_1和ω_2,然后迭加而得固有頻率ω。这样将使計算大为簡化,且能得到滿意結果。文末提供了实驗驗証数据。 本文的計算可用于各种錐度的圆錐壳。同时为了論証上述方案的正确性,計算了a=0即圆柱壳情况;并給出...

This paper first introduces four broad approaches to the Classification of world climates as follows: 1.classifications based on the elements of physical geography,such as natural vegetation,hydrologic conditions and natural landscape; 2.classifications basedon the elements of climates such as temperature, precipitation, etc.; 3.classifications based on the causes of climates such as net radia- tion,air mass source regions and frontal zones,etc.; 4.classifications based on the application of agriculture,transporta- tion,industry and human comfort. The second part of this paper are the comments on the K(?)ppen Cla- ssification,Alissov Classification and Strahler Classification. In third pard,the author sets forth the following views of world cli- mate classification: 1.the criteria employed in the differentiation of climatic types shou- ld reflect their origins. 2.The climate classification we seek must be useful in guiding land- use planning and increasing production. According to tee above views the author adopted Strahler Classifica- tion in our text book《Meteorology And Climatology》,with the following amendments: 1.In southern and southeastern Asia monsoon climates are very preva- lent.It is necessary to add three climate types,namely,tropical monsoon climate,subtropical monsoon climate and temperate monsoon climate.They are different from the tropical wet-dry climate,the humid subtropical climata and the humid continental climate in other areas. 2.It is preferable to add a tropical marine climate type which is characteristic of the climate on tropical islands and along tropical wind- ward coasts. 3.The“trade wind litteral climate type”is left out because the re- gions is classified in Strahler Classification Figure seem to belong to tro- pical monsoon climate and tropical marine climate respectively. The classifications of world climate in our text-book are shown in table 3 and figure 2.

一、引言:世界气候分类法简介,将世界气候分类法归纳为四大类:(一)以自然地理要素为基础的气候分类法,(二)以气候要素为基础的气候分类法,(三)以气候形成因素为基础的气候分类法,(四)以应用目的为基础的气候分类法。二、几种主要气候分类法评议:(一)柯本气候分类法评议,(二)阿里索夫气候分类法评议,(三)斯查勒气候分类法评议。指出上述三种分类法各自的优点和缺点。三、作者提出的气候分类观点和采用的气候分类法:世界气候分类应突出以下两个观点:(一)发生学观点:世界气候分类所采用的标准要能反映气候形成因素的综合作用,应从发生学观点进行气候的动力分类。(二)生产实践观点:气候分类应充分揭示与人类生活和生产实践密切有关的气候特征,便于制定土地利用规划和国民经济增产计划,充分利用气候资源,改造不利气候条件。根据上述观点,作者在所主编的《气象学与气候学》教材中,基本上采用斯查勒分类法,但做了以下三点修改:1.南亚和东南亚季风气候显著,无论从发生学观点,生产实践观点和联系我国气候实际来讲,都应按纬度带增加热带季风气候,付热带季风气候和温带季风气候三个类型。2.某些热带岛屿和热带迎风海岸具有海洋性气候特征,应加列一“热...
