    This paper investigates the general and complete form of slope-deflection equations used in structural analysis. The word "complete" indicates that all the possible deformations (deflections and rotations) and all the strain energies (due to shear, direct stress and flexure) are included in the equations. The definitions, numbers, and relations of member constants are then discussed and the general equations for computing these constants are given.

    This paper investigates the general and complete form of slope-deflection equations used in structural analysis. The word "complete" indicates that all the possible deformations (deflections and rotations) and all the strain energies (due to shear, direct stress and flexure) are included in the equations. The definitions, numbers, and relations of member constants are then discussed and the general equations for computing these constants are given. By neglecting the factors of minor importance, the general form is reduced to the usual slope-deflection equations. Some special forms of such equations which are useful in certain practical problems are also discussed briefly, such as the slope-deflection equations including the effect of direct stress on flexure and the slope-deflection equations of semi-rigid frames. Slope deflection equations for trussed bents are also presented.

    Even though in the application of adsorption to industry or research one almost never deals with solutions containing only a single solute, yet the number of investigations on the adsorption from mixed solutions is very limited. Following the lead of Freundlich the generally held opinion is that the effect of one adsorbate on the adsorption of another is simple displacement. While this may be true for some special cases, it is undoubtedly too simple to be of general validity, because the various interactions, such as solid-solvent, solute-solute, solute-solvent, have been neglected in this theory. In the theoretical study of chromatography it is necessary to know the equation for the adsorption isotherm when more than one solute are present in the solution. The most widely adopted equation for this purpose is (x/m)_a=k'_aC_a/(1+k_iC_i) (1) This equation can be easily derived from that for a single adsorbate: x/m = k'C/ (1+kC) (2) by assuming that the presence of an additional solute merely reduces the available surface area of the solid. Formally, this equation is analogous to that of Langmuir for the adsorp- tion of gaseous mixtures, replacing pressures by concentrations, but it is actually an empirical equation, because the numerical values of the k's can be obtained only from experimental data and their physical significance is not at all clear. This equation predicts the de-pression of the adsorption of one solute by another. While it is in line with the current idea, there is no experimental proof of its validity. It is the dual purpose of the present investigation to substantiate or disprove the dis- placement theory and to test the applicability of equation (1). We have studied the adsorption from binary solutions of hydrochloric, acetic, and oxalic acids by sugar char. The adsorbates are chosen because of their widely different strength. Sugar char is chosen because it has been shown from previous studies that with this adsorbent the experimental data for single adsorbate follow equation (2). The experimental results are given below: HCl-CH_3COOH and CH_3COOH-H_2C_2O_4 systems: (1) The adsorption of any acid is less than when it is present alone; (2) When the corresponding (x/m)'s are plotted, straight lines with negative slopes are obtained; (3) The slopes of these straight lines vary with the concentration of the acid being displaced; (4) The order of the displacing power, measured by the slope, is HCl> CH_3COOH > H_2C_2O_4, while the order of adsorption is just the reverse; (5) Equation (1) is not valid. HCl-H_2C_2O_4 system: (6) The adsorption of HCl is decreased; (7) When its concentration is higher than about 0.005 N, the adsorption of oxalic acid is increased; at lower concentrations the adsorption is decreased; (8) The higher the concentration of HCl is, the more pronounced will be the increase of adsorption of oxalic acid; (9) Corresponding (x/m)'s give straight lines whose slopes change sign as C_ox increases beyond 0.005 N. From (3) and (4) it is concluded that the observed decrease of adsorption is not due to simple displacement. Based on the hypothesis that it is primarily the solvent which is displaced with the subsequent shift of equilibrium, a mechanism is proposed to account for the effect of one solute on the adsorption of another, which seems to agree with all the observed results. The increase of the adsorption of oxalic acid disproves conclusively the displacement theory. The fact that there is a critical concentration below which the adsorption of oxalic acid is decreased indicates that there are two opposite influences at work. It is suggested that three factors contribute to the increase of adsorption of oxalic acid: (a) the decrease of dissociation; (b) the lowering of solubility; and (c) electrostatic effect. To determine the relative importance of these factors requires further investigation. Finally, an empirical equation involving three constants has been derived to represent the adsorption of oxalic acid in the presence of hydrochloric acid.

    在此工作中我們研究了三種混合酸的吸附。在鹽酸-酸的體系中,鹽酸增加糖炭對於草酸的吸附量,倘若草酸的濃度超過0.005N。這個事實否定了在混合酸中各溶質間的作用是彼此頂替的說法。在醋酸-草酸及醋酸-鹽酸的混合溶液中,各酸的吸附量皆較其單獨存在時低。根據實驗的數據我們指出了各家說法的可疑之點。我們認為在混合溶液中吸附量之減少主要是因為溶質甲頂替了表面上的溶劑,因而使溶質乙的吸附量降低。若是溶質甲能使溶質乙的電離度或溶度降低,或增加溶質乙的Gegen-ion,則能使乙的吸附量增加。因為Langmuir式的混合吸附公式不能代表吸附之增加,我們提出了一個可以此較滿意的代表實驗結果的三常數經驗公式。各溶質的吸附量皆成直線關係。對此結果我們不能作定量的解釋,雖然此種現象與我們的假設並不矛盾。

    The Austausch coefficient may be obtained by wind structure. 1902 Ekman established the wind spiral theory in the friction layer. From the observed wind spiral, we may calculate of the Austausch coefficient by this theory. 1952 considered effect of the change of pressure field with height; i. e. the thermal wind effect, and found excellent results. But, Formula holds only for the condition in the stationary current flow, or in the stationary temperature pressure field and uniform temperature pressure gradient.In this paper, we consider the unstationary effect, as calculating the Austausch coefficient in the friction layer, and obtain a more general formula. Under some special constrains, it tends to be the or Ekman's formula. Then, this formula may be more accurate in calculation and more wide in application.Some calculations based on observed data by using these three different formulas are presented and compared.

    摩擦层中湍流系数,利用风标的分布,可以测定之。1902年,爱克曼创立了摩擦层中风标螺线,利用风标螺线,可以测定摩擦层中的湍流系数。1953年,莱赫特曼考虑了气压场随高度的变化,即热成风的因素,获得了良好的结果。但是,莱赫特曼公式之应用,只限定于恒态吹流,或恒态均匀温压场的条件之下,方能准确使用。这样是在一般情况之下难以满足的。关于摩擦层非恒态问题,1947年赵九章、裘碧克曾经讨论过。本文仅就非恒态湍流系数测定问题予以进一步探讨。并得到了较有广泛意义之公式。而莱赫特曼公式,系属温压场恒态,温压场中温度、压力梯度在均匀情况之下,该公式之特解。爱克曼范式,系属气压场稳定,温度梯度恒态为零时,该公式之特解。这样,该公式的计算,使得湍流系数测定工作精确化和广泛化。 最后,本文作了一些实际资料的计算与分析,和讨论在自然环境中湍流系数的变化。
