We have made three pyrex floats of the bulb-rod stream-line type, modified from that used in the Trail laboratories. These floats possess cach a thick-walled bulb 6.5 mm in diameter, with an upper rod 3.5 mm long and a lower rod 8 mm long, each rod being 2.5 mm in diameter and forming an angle of 60° at the end. With baths having temperature fluctuations within ±0.0005°, the velocity-temperature relationship has been determiued in the neighborhood of their flotation temperatures.

We have made three pyrex floats of the bulb-rod stream-line type, modified from that used in the Trail laboratories. These floats possess cach a thick-walled bulb 6.5 mm in diameter, with an upper rod 3.5 mm long and a lower rod 8 mm long, each rod being 2.5 mm in diameter and forming an angle of 60° at the end. With baths having temperature fluctuations within ±0.0005°, the velocity-temperature relationship has been determiued in the neighborhood of their flotation temperatures. It is found that the temperature iuterval in which such a relationship is linear is much more extensive when the flotation temperature of the float is lower. Correspondingly, the velocity interval is only slightly larger. The results are as follows:Float Flotation Temperature Velocity intervalNo. temperature, ℃ interval, ℃ mm/sec1 28.86 ±0.08 ±0.192 24.17 ±0.12 ±0.203 17.79 ±0.26 ±0.22So it is advcntageous to use floats with lower flotation temperatures. With Aoat No. 2 we have determined the deuterium contents of two samples of heavy water.Besides, we have measured the effect of pressure on the flotation temperatures of these floats. Float No. 1 has been studied in more detail with the result that the relationship between the flotation temperature and the pressure is linear in the investigated pressure range of 48 cm Hg in the neighborhood of one atmosphere.

我們对於三只“球柱流線型”Pyrex玻璃浮沉子测定了升降速度与温度间的关系, 求得在室温左右,當浮定温度愈低時,並直線性關係的温度範圍愈大,相應的速度範圍也略大。在28.86°時,直線性關係的温度範圍為±0.08°,直線性關係的速度範圍為±0.19毫米/秒。在17.79°時,相應的數據是±0.26°和±0.22毫米/秒。因此,用浮定温度较低的浮沉子,可在約半度的温度範圍內選测两点,來求得重水的濃度。其次,我們在1大氣壓附近,測定了一只厚壁浮沉子在48厘米汞柱的壓力變動範圍内,浮定温度与压力变动呈直線性關係。

A general theoretical approach is developed to treat the effect of point imperfections on the spin waves in a ferromagnetic crystal. Special attention is paid to the formation of localized modes. As an example, the calculations have been carried out for a one-dimensional linear lattice. The main results obtained indicate the following features. A substitutional magnetic impurity atom may introduce more than one localized mode of spin waves. The conditions for the localized modes to appear and the positions of their energy levels are given in terms of J'S'/JS and J'/J. Here S' and S are respectively the spin quantum number of the impurity and that of the normal atoms. J' and J are respectively the exchange integral between an impurity and its neighbors and that between the normal neighboring atoms. Highly concentrated strains and interstitial atoms which cause the exchange interaction between the atoms in their neighborhood to increase lead also to the formation of localized modes. Furthermore, the dipole-dipole interaction has been taken into consideration with the conclusion reached that it should not destroy the existence of these localized modes. Discussions have been given to the discrete energy levels which appear below the continuous spectrum in case of J'<0. It is pointed out that the Holstein-Primakoff approximation adopted in the present work is not quite legitimate for certain cases in which on one or more atoms the spin deviation becomes not very much smaller than 2S or 2S'.

本文提出了一个处理磁性杂质或其他缺陷在磁性晶体中对自旋波频谱的影响的一般理论方法,并特别着重讨论了局域模自旋波。以一维线性格子为例进行计算的结果显示出:一个代位磁性杂质,可能产生不只一个高于连续带顶的局域模。其产生的条件和其能级位置均通过J′S/JS和J′/J表达出来,这里S′和S各为杂质原子和基质原子的自旋量子数,J′和J各为杂质与近邻之间和一般近邻之间的交换作用系数。高度集中的应变和间隙原子如致使邻近处的交换作用增大,也导致局域模的出现。我们也考虑了磁偶极矩相互作用的影响,证明其并不破坏这些局域模的存在。我们还讨论了在J′<0时,连续谱之下出现的局域模能级。我们也指出,在某些情况下,自旋偏离过于局域在较少数的原子上,本文中所采用的Holstein-Primakoff近似就不十分合法了。

On the bases of these general formulas, formulas for computation are given for the step type concentrator with either conical, or exponential, or catenoidal transition section at the step; for the conical concentrator with a cylinder at its small end; and for the catenoidal concentrator with a cylinder at its large end.

In the present paper general formulas are derived for the resonant frequency, the amplication factor MP, the form coefficient (?), and the input impedance of a composite concentrator horn. On the bases of these general formulas, formulas for computation are given for the step type concentrator with either conical, or exponential, or catenoidal transition section at the step; for the conical concentrator with a cylinder at its small end; and for the catenoidal concentrator with a cylinder at its large end. Values of MP and (?) as well as the dependence of the input impedance on kl2 in the neighborhood of the resonant frequency are actually computed for the above mentioned composite concentrators. Design curves are given. Check by experimentation shows that the theoretical values basically agree with the experimental results.
