The solubilities of potassium dichromate in mixtures of light and heavy water with various D_2O-contents hsve been measured at 25±0.03°. The solubility is expressed in two different ways: (1) S_n, the number of moles of K_2Cr_2O_7 dissolving in 55.51 moles of H_2O-D_2O mixture with the mole fraction of D_2O equal to n; (2) S_x, the number of grams of K_2Cr_2O_7 dissolving in 1 gram of H_2O-D_2O mixture with the weight fraction of D_2O equal to x (see Table 1, pp. 321-322).

The solubilities of potassium dichromate in mixtures of light and heavy water with various D_2O-contents hsve been measured at 25±0.03°. The solubility is expressed in two different ways: (1) S_n, the number of moles of K_2Cr_2O_7 dissolving in 55.51 moles of H_2O-D_2O mixture with the mole fraction of D_2O equal to n; (2) S_x, the number of grams of K_2Cr_2O_7 dissolving in 1 gram of H_2O-D_2O mixture with the weight fraction of D_2O equal to x (see Table 1, pp. 321-322). The data are plotted in Fig. 1 (p. 323), and treated with the method of least squares, which yields the following empirical formulae: S_n = 0.5024 - 0.1467 n + 0.0174 n~2 S_x = 0.1478 - 0.0540 x + 0.0049 x~2 These formulae possess a mean deviation of ±0.18%, but the total experimental error is estimated to be about ±0.25%. From these formulae we obtain S_n~(D_2O)=0.3731; S_x~(D_2O)=0.0987. As D_2O, H_2O and K_2Cr_2O_7 constitute a three-component system, the composition of the liquid phase with K_2Cr_2O_7 saturated at 25°, expressed either in mole fractions or in weight fractions, is given in Table 2 (p. 324). The system represented by weight fractions is shown in Fig. 2 (p. 325). The above formulae permit an estimation of the solubility of potassium dichromate in HDO at 25°: S_n~(HDO)=0.4291 S_x~(HDO)=0.1208 In the present case of solubility phenomena, the substitution of deuterium for the second protium atom in the water molecule produces an effect only amounting to 76% of that caused by the substitution for the first protium atom. This agrees with previous observations on the density, the temperature of density maximum, the freezing point, the boiling point, the heat of fusion, the heat of vaporization, the vapor pressure, the viscosity, etc.

我們在25±0.03°測定了重鉻酸鉀於輕水-重水混合物中的溶解度,由此得到下列經驗式: S_n=0.5024-0.1467n+0.0174n~2 S_x=0.1478-0.0540x+0.0049x~2 式中S_n表示每55.51克分子含n克分子分數D_2O的輕水-重水混合物中所溶K_2Cr_2O_7的克分子數;S_x表示每克含x重量分數D_2O的輕水-重水混合物中所溶K_2Cr_2O_7的克數。實驗誤差約±0.25%。由式得出:S_n~(D_2O)=0.3731;S_x~(D_2O)=0.0987。重鉻酸鉀在25°的溶解度舆重水濃度間所呈現的這種非直線性關係,表明了第二個D原子代入水分子中時所產生的效應只有第一個D原子代入作用的76%。 從這兩個經驗式可以計算出重鉻酸鉀在25°時在HDO中的溶解度:S_n~(HDO) =0.4291;S_x~(HDO) =0.1208。

A new approximate method for treating nn and pp pairing force in nuclei is presented. In this method the difficulties connected with the application of BCS-Bogolubov method to nuclei such as the non-conservation of the number of particles, the apperance of spurious states, and non-orthogonality between wave functions of different excited states are avoided. But the method can be conviently adopted only when the number of particles n and the number of levels Ω considered are small (n ≤10, Ω≤10 ). Also the approximation of this method is good onlv under such conditions. In this method the many-body nature of the excitation is displayed explicitly without introducing the conception of quasi-particles. The excitation of the system can be divided into two classes. The first class of excitation is a kind of single particle excitation embedded in a many-body system under the action of the pairing force. This would correspond to the excitation of a single quasi-particle a_v~+av0 or to two quasi-particle excitation of the type α_v~+β_(v')~+,α_v~+α_v'~+(v'±v) etc. in the BCS-Bogolubov method. The second class of excitation is a pair excitation in which the distribution of the conjugated pairs of particles among the levels is altered. This type of excitation would correspond to superposition of quasi-particle excitations of the type α_v~+β_v~+,α_v~+β_v~+α_μ~+β_μ~+, Also examined is the effect of pairing force on the β- and γ-transition probability in the new formalism. In general, β-transition is retarded by the pairing force while in γ-transition the effect of pairing force varies according to the nature of the relative excitation between the initial and final states. When the relative excitation is of the first class, the transition is retarded to various extent, depending on the nature of the γ-transition. If the relative excitation is of the second class, the transition is forbidden when the pairing force is not in action, and is allowed only for electric transition arising from the charge-current distribution when the pairing force is present. Finally this method is applied to investigate the effect of pairing force on the intrinsic spectra and β-transition in 72Hf178 as an example.

本文提出了一个处理原子核中nn及pp对力的近似方法。这个方法避免了通常将方法应用于原子核所引起的困难,例如粒子数不守恒,假态的出现以及不同激发态波函数不正交等。但这个方法只有在所需考虑的粒子数n及能级数Ω不太大时(n≤10,Ω≤10)才能较方便地被应用,近似程度才比较好。在这个方法中,毋须引入准粒子的概念,激发的多体性质被明显地表示出来。系统的激发可分为两大类型。第一类型激发是一种以多体系为背景的单粒子跃迁,相应于一个准粒子的跃迁α_ν~+α_ν,或两个准粒子的激发α_v~+β_v′~+,α_v~+α_v′~+(vv′)。第二类型激发是对激发,在这种激发中,各能级上共轭粒子对的填充几率改变了,相应于共轭的准粒子对的激发α_v~+β_v~+,α_v~+β_v~+α_μ~+β_μ~+,…. 本文还考察了对力在r及β跃迁中的影响。在β跃迁中,对力一般是使跃迁受阻。在r跃迁中,对力的效应随初末态间的相对激发类型不同而异,如相对激发属于第一类型,则跃迁受阻,受阻程度随跃迁的电磁性质不同而有所差别,如相对跃迁属于第二类型,则在无对力作用时跃迁是禁戒的,在对力作用下也只有由电荷电流所产生的电跃迁是允许的。 最后本文以Hf~...

Basing on the dispersion relation, an approximate method is suggested to obtain the scattering amplitudes. In principle we can apply this method to the study of the amplitude behaviour of low and high energy scattering. For high energy π±p, K±p, pp, and pp scattering, the primary comparison with experiments is made by two parameters. It is found that the theory agrees with experiments.
