This paper reviews the observational facts and theories on the airflow over small mountains. Special emphasis is laid to point out and discuss the controversies in the theory of lee waves among different writers. According to present author controversiesare due to (1) the difference in scale of the mountain and (2) the choice of the upper boundary condition. When l is comparable to the critical value , where l is the half-width of the mountain, lee waves occur. When there is an upper solid lid or a discontinuity...

This paper reviews the observational facts and theories on the airflow over small mountains. Special emphasis is laid to point out and discuss the controversies in the theory of lee waves among different writers. According to present author controversiesare due to (1) the difference in scale of the mountain and (2) the choice of the upper boundary condition. When l is comparable to the critical value , where l is the half-width of the mountain, lee waves occur. When there is an upper solid lid or a discontinuity in the atmosphere lee waves occur.In the first case the forced vibration is in resonance with natural vibration. In the second case there can exist only vibrations of certain wave lengths, which appears as those of the lee wave. The physics of lee waves is thus clear.

本文总结了小地形对于气流的影响。文中着重地指出和讨论了过去背风波理论中的矛盾。作者认为这些矛盾是由于山的大小选择和上界边界条件的选择而引起的。当山的宽度的一半l≈(L_S/2π)时(L_S=u/(g/θ αθ/αz)(1/2)),和当大气中有一个固定的盖或不连续面存在时,背风波出现。 在第一种情况下,山的强迫振动与大气中的自由振动共鸣;在第二种情况下,只具有某些滤长的振动可以存在,这波长就是背风波的波长。这样的讨论背风波的物理意义就清楚了。

The purpose of this series is to make a thermodynamic analysis of the Fe-C system with a minimum of assumptions and to revise the equilibrium diagram of the same system in the light of the results of this investigation. In this paper, the first of the series, activities in liquid Fe-C alloys have been evaluated up to saturation, using Richardson and Dennis' data123 on dilute solutions of carbon in liquid iron and Darken and Smith's model~([1]) for carbon dissolved in austenite with certain modifications.A parameter α_c defined as logγc/N_Fe~2 with reference to graphite as the standard state is plotted against N_c for both austenite and Fe-C melt in order to facilitate the evaluation of α_(Fe) by graphical integration. Smith's data~([1]) on equilibrium between austenite and gaseous mixtures (CO_2/CO, CH_4/H_2) are re-treated to yield α_c~γ-N_c~γ curves for 800° and 1000℃ as shown in Fig. 1. On the assumption that L_c~γ the relative partial molal enthalpy of carbon in austenite, does not chan preciably with temperature, the α_c~γ-V_c~γ curve for 1153℃, the iron-graphite eutectic temperature, is obtained by extrapolation and found to lie above the graphite saturation point. This fact seems to indicate that the limit of application of Darken and Smith's model is reached somewhere around N_c~γ=0.0661 (1.50%) and a point of inflection should occur at this concentration. The above-mentioned assumption has been semi-quantitatively proved in this paper and will be discussed further in another paper of this series.In a similar manner, α_c~l-N_c~l curves for liquid Fe-C alloys are drawn through the experimental points of Richardson and Dennis on equilibrium between CO_2/CO mixed gases and dilute solutions of carbon in liquid iron at 1560° and 1660℃ as shown in Fig. 1. The curves are extended up to N_c~1=0.15 on the basis of Darken and Smith's model using 3600 cals. as the energy of interaction at 1560℃ between carbon atoms in the neighbouring interstitial sites as recommended by Richardson and Dens. Then, a suitable curve is drawn between N_c~l=0.15 and the graphite saturation point for 1560℃ to meet certain requirements, and a corresponding curve for 1660℃ is obtained by extrapolation, assuming that L_c~l, the relative partial molal enthalpy of carbon in liquid iron, does not change appreciably with temperature. Thus, α_c~l-N_c~l curves for 1560° and 1660℃ are completed from low carbon concentrations up to saturation. The activities of carbon in Fe-C melts at 1600℃ with reference to graphite as the standard state are readily obtained at different carbon concentrations by interpolation, from which the reversible electromotive forces of a concentration cell of the type Fe,C|slag, C_2~2|Fe,C(sat.) have been calculated and found to agree fairly well with the experimental values obtained by and as shown in Fig. 2. This agreement may be taken as partial confirmation of the choice of N_c~l=0.15 as the limit of application of Darken and Smith's model to liquid Fe-C alloys.From α_c~l-N_c~l curves for 160°and 1660℃, L_c~l is easily calculated to be 3930 cals., and by combining this value with certain other data, the following equation is obtained:C(gr.)=C[%]; AF°=3930-9.21 T,which differs considerably from Chipman's equation AF°=8900-12.10T given in the 1951 edition of the "Basic Open Hearth Steelmaking". It is believed that the present author's equation is more reliable than Chipman's in view of the uncertainties involved in the derivation of the latter especially regarding the evaluation of the enthalpy of solution of graphite in liquid iron.By graphical integration of the Gibbs-Duhem equation, the activities of iron in Fe-C melts with pure liquid iron as the standard state are obtained at different carbon concentrations and plotted against N_c~l in Fig. 3. The α_(Fe)~l-N_c~l curve thus obtained is independent of temperature. With the aid of Fig. 3 and certain other data, the activities of iron in an Fe-C melt and austenite both saturated with graphite at the eutectic temperature are evaluated with pure γ iron as the common standard state and found to be practically equal as required by the eutectic equilibrium. This fact renders additional support to the choice of N_c~l=0.15 as the inflection point of the α_c~l-N_c~l curves.The shape of the α_c~l-N_c~l curves is briefly discussed from a structural viewpoint.

作者在本文中综合分析了关於液态铁碳合金中碳活度测定的諸家研究结果並比较其优劣. 然后根据Richardson与Dennis用CO_2/CO平衡法的实验数据,用Darken与Smith的统计模型与最少假定,导出了液态鉄碳合金中α′_c与N′_c的关系(α′_c=logγ′_c,/(N_Fe′)~2,标准状态为石墨),并温度对此关系的影响.计算结果符合於(i)鉄液内石墨溶解度的实验数据;(ii)与用电动势法测定液态铁碳合金中碳活度的实验数据;及(iii)奥氏体、铁液、石墨共晶平衡的要求. 根据本文所导出的α′_c-N′_c曲綫,作者算得石墨在鉄液内的溶解热为3930卡;然后依此及其他必需数据,导出下列关系:C(石墨)=C[%],△F°=3930-9.21T. 最后作者从液态铁碳合金结构的观点讨论了图1中α′_c-N′_c曲綫的形状.

Methods of synthesis and the properties of ammonium antimonylgluconate are reported. Addition of a solution of antimony trichloride in conc. aqueous gluconic acid to conc. ammonium hydroxide gave the said drug. It can also be prepared by the interaction of antimony triethoxide and ammonium gluconate. The antimony content of the product can be varied over wide limits (up to, say, 50% Sb), being dictated by the choice of the relative amounts of starting materials. Ammonium antimonylgluconate is readily soluble...

Methods of synthesis and the properties of ammonium antimonylgluconate are reported. Addition of a solution of antimony trichloride in conc. aqueous gluconic acid to conc. ammonium hydroxide gave the said drug. It can also be prepared by the interaction of antimony triethoxide and ammonium gluconate. The antimony content of the product can be varied over wide limits (up to, say, 50% Sb), being dictated by the choice of the relative amounts of starting materials. Ammonium antimonylgluconate is readily soluble in water, practically insoluble in alcohol. Its aqueous solution is unstable towards heat, acids and bases. Direct titration of the untreated sample with iodine has been found unsuccessful, since the rate of oxidation of trivalent antimony to its pentavalent state is slow enough to give rise to shifting end points, presumably due to some protective action on the part of the gluconic acid residue. This behavior is to be contrasted with that of potassium antimonyltartrate (tartar emetic), where oxidation of antimony with iodine occurs instantaneously.

1.葡萄糖酸锑铵可由三氯化锑及葡萄糖酸的浓溶液,与浓氨水作用而得.亦可用亚锑酸乙酯及葡萄糖酸铵制备.在操作上以前法较简便.成品的含锑量可因锑化剂用量的多寡而不同。2.葡萄糖酸锑铵极易溶于水,水溶液加热或遇酸、鹼时均不稳定。水溶液与碘作用时,锑的氧化(由三价至五价)速度较慢,不能直接滴定,这一点和酒石酸锑钾(吐酒石)不同,后者可以直接用碘滴定,不必经过破坏。
