The circumferential vibration of a hollow quartz cylinder has been thoroughly studied. The empirical relation connecting the dimensions of the cylinder and the frequency of vibration has been formulated, and the temperature coefficients of the frequency determined. The temperature coefficient is practically zero for a wide range of temperature, when the ratio of the internal radius to the external radius of the cylinder approaches a value which is very close to 0.5.

Hair-line cracks or flakes in steel are known to be associated with the presence of hydrogen. A prevailing theory states that the crack formation is due to disruptive hydrogen pressure being built up in defects in steel. However, little was known regarding to the nature of these defects and the detailed mechanism of the hair-line crack formation.

Hair-line cracks or flakes in steel are known to be associated with the presence of hydrogen. A prevailing theory states that the crack formation is due to disruptive hydrogen pressure being built up in defects in steel. However, little was known regarding to the nature of these defects and the detailed mechanism of the hair-line crack formation. An attempt was made in the present research to investigate this problem by means of internal friction measurements. The preliminary experiments show: (1) The presence of hydrogen in certain steels may give rise to the appearance of an internal friction peak when internal friction is plotted against the temperature of measurement; (2) a slight amount of cold-work or soaking at a given temperature has a considerable effect on the optimum temperature of the observed internal friction peak, which indicates that the internal friction peak may be connected with the defects or stress condition in steel; (3) the internal friction peak shows an anomalous amplitude effect, i.e., at a given temperature of measurement an internal friction peak is obtained when the internal friction is plotted against the stress amplitude. Such an anomalous behavior is similar to that previously observed by. one of the authors (Ke) in the case of aluminimum containing 0.5% Cu. It is therefore considered that the internal friction peaks observed may be related to the interaction of hydrogen with the dislocations in steel.

钢的内部发裂已经公认为与钢中的氢气有关。现有的理论认为这是由于氢气聚集于钢中的内部缺陷产生破裂压力所引起,然而关于缺陷的性质和引起内部发裂的详细机构迄今还没有明确的了解。本文尝试用内耗测量的方法来研究这个问题。初步实验的结果指出: (1)氢在钢中可以引起内耗峰(将内耗表示为测量温度的函数时); (2)轻微冷加工或保温对于内耗峰的颠值温度有着显著的影响,这表示所得的内耗峰与钢中的缺陷和应力状态有关系; (3)所得的内耗峰表现有反常的振幅效应,即在一定的观测温度时,如将内耗表示为外加应力的函数,则也得到一个内耗峰。这与本文作者之一以前在铝铜合金中所观测到的反常内耗峰的性质和表现相同,因而所得的内耗峰可能是由于氢与钢中的原子脱节的交互作用所引起来的。

The main difficulty of the one-electron theory of optical activity lies in the calculation of the so-called vicinal actions. This may be overcome, as suggested in the present investiga- tion by assuming that the vicinal actions are due to the interactions of various chemical bonds in the molecule with the chromophoric electron. For the calculation of these interactions the charge distribution of a single covalent bond is assumed to consist of two nuclei, each of unit positive charge, separated by the bond distance and two electrons with opposite spins and a spherically symmetrical orbital eigenfunction represented by (?) where r is the distance measured from a certain point on the bond axis and near the center of the bond. The location of this point is so determined that the model will give the proper dipole moment of the bond. The exponent α, which determines the extent of diffusivity of the electron cloud, is obtained by an approximate variational treatment. The quadruple moment of this model, calculated for the C-H bond, agrees very well with that estimated by Lassettre and Dean from a study of the potential barrier hindering the internal rotation of the ethane molecule. To test the theory and also to illustrate the procedure which is followed in calculating optical rotations using the new model of vicinal actions, the optical rotations of several methyl derivatives of cyclopentanone have been calculated and the following conclusions have been reached: (1) The proposed model gives rise to optical rotations in agreement with the observed values. (2) The effect of the internal rotation of the methyl group on the molecular rotation [M]_D of 3-methylcyclopentanone is large, [M]_D being +44° and -130° for the cis- trans-conformations, respectively. (3) The observed [M]_D may be regarded as composed of two parts, namely, the contribution from the multipole terms and that from the orbital overlapping. The latter corresponds to the "incomplete screening of atomic nuclei", and has been regarded as the most important vicinal action in earlier calculations. In the present work, it is shown, however, that this effect contributes only a few percent of the total [M]_D, unless the perturbing group is very near to the chromophoric group as it is in the case of 2-methyl- cyclopentanone. The failure of the previous calculations is, therefore, due mainly to the omission of the multipole (especially the quadrupole) terms. (4) The absolute configuration of 3-methylcyclopentanone, indicated by the present calculation, is the opposite of the one suggested by Eyring, since he based on the overlapping contribution alone, which bears a sign opposite to that of the total [M]_D (5) That the observed [M]_D of 2,4,5,5-tetramethylcyclopentanone is considerably smaller than that of 2,4-dimethylcyclopentanone may be due to one or both of the following possibilities: (a) that the conformation of the 2- and 4-methyl groups slightly deviates from the trans-position in the tetra-methyl compound, due to the presence of the two additional methyl groups; (b) that the two additional methyl groups in 5,5-positions are not exactly symmetrical with respect to the ring so that they make contributions to [M]_D.

本文在量子力學的單電子旋光理論的鄰近作用問題上,作了如下的貢獻: 1.指出旋光度應由分子中各化學鍵,而不是分子中各原子(如像前人所假定的)對於生色團電子的微擾作用來計算,兩者的主要不同點在於是否考慮鍵的多極矩。 2.建議在旋光度的計算中,共價單鍵可以看作是由兩個處於鍵端的正電荷和一個以單中心狀態函數,表示出來的電子雲所組成。根據這個假定計算了環戊酮的甲基衍生物的旋光度,其結果與實驗值甚爲一致(詳見結果討論)。 3.計算結果證明甲基的內旋轉對於旋光度的影響很大,例如順式和反式構型的3-甲基環戊酮的旋光度,應分別為+44°和-30°。 4.指定了3-甲基環戊酮的絕對構型,其結果Eyring所指定者相反。
