This paper applies Kirkwood's method for calculating the configurational free energy E of a solid solution to a solid solution AB3 inhabiting a face-centred cubic lattice. In this method, the free energy F is expressed as a series in (kT)A~(-1), and our calculation goes as far as the coefficient of (kT)~(-4).

本文应用了Kirkwood方法去计算面心立方体的固溶体AB_3的自由能。在这个方法中,自由能被表为(kT)~(-1)的幂级数。我们的计算一直算到了(kT)~(-4)的系数。 如果称原子排列的秩为S,称忽略O(kT)~(-n)的自由能为F_n,那末F_n与S的关系对于不同的n(n=2,3,4,5)是极不同的。事实上,F_3,F_5和S=0处始终为极小,使理论中看不到超点阵的结论。这说明自由能F对(kT)~(-1)的展开的级数收敛极慢。 将F表为 η≡e~(-(V_(AA)+V_(BB) - 2V_(AB))/kT) - 1的级数(式中V_(AA),V_(BB),V_(AB)代表最近邻AA,BB,AB对的作用能)而称忽略O(η~n)的自由能为F_n~′那末F_2~′,F_3~′依然不给我们超点阵的结论,但由F_4~′,F_5~′我们非但获得了超点阵,并也看到了S的突变及固溶体的潜热。F_4~′,F_5~′是极相似的,使我们相信它们近似于真正的F。

According to the actual practical condition of acousto-optical deflectors, by solving Dixon equations of abnormal Bragg diffraction under the condition of fixed incident light direction 1)1, the functional dependences of the ultrasonic wave direction (?)a. which gave rise the acousto-optical interaction and the diffraction light direction (?)2 on the frequency f are obtained. From the (?)a-f relationship, the important design parameters, i.e., the Bragg bandwidth and the transducer length, can be determined accurately. The (?)a-f relationship shows good linearity, hence the previously proposed corrections on scanning linearity appear to be unnecessary.

按声光偏转器的实际使用情况在入射光方向固定不变的条件下求解反常布拉格绕射的Dixon方程,得到起作用超声方向和绕射光方向随频率f的变化关系。由-f关系可精确决定声光偏转器的布拉格带宽和换能器长度等重要设计参数。所解出的-f关系具有良好的线性,因而以往所作关于矫正扫描线性的探讨显得多余。

Water regulation or control by storage capacities is often one of the main water resource problems. The hydrologic magnitude has a significant stochastic component, the theory of probability and statistics may be applied to determine the probability of water supply, and mean water deficit, surplus in a reservoir of the annual flow regulation, that is, the increase of low flows from water stored partly during flood seasons. In the first part, this paper discusses the probability of the annual flow regulation. In the second part, this paper develops a method of calculation of the mean water deficit, and surplus of the annual flow regulation. It starts with the following formula where Kεp may be determined by the probability distribution function F (Kε), For detailed discussion of these formulas see references[ 1] ,[2] . Then equations of the mean water surplus and deficit are given as

水库的水量调节,是开发水利资源的重要问题之一。水文量具有明显的随机成分,可以应用概率论与数理统计来确定年调节水库供水概率、不足水量与多用水量的多年平均值。 本文的第一部分论述了年调节水库供水的概率或保证率。 本文第二部分建议确定年调节水库不足与多用水量多年平均值的计算方法。按著者在文献[1]中所推导的公式(1)出发式中 Kεp。可由F(Kε)的概率分布函数确定(对上述公式的导出与讨论可参阅参考文献(1)、(2))。 得到计算年调节水库多年平均多用水量与不足水量的公式:(4)
