The origin of the system of bands around 2482 A.U. observed in a mercury lamp has been given evidence as due to mercury molecular ion. Quantitative determination of the intensity variations as a function of pressure and current of the 2482 bands and other band of neutral molecules, shows marked difference between 2482 bands and other bands. All the differences can only be explained on the basis of an ionic origin of the 2482 bands. The excited state of the molecular ion that emits 2482 bands is given evidence...

The origin of the system of bands around 2482 A.U. observed in a mercury lamp has been given evidence as due to mercury molecular ion. Quantitative determination of the intensity variations as a function of pressure and current of the 2482 bands and other band of neutral molecules, shows marked difference between 2482 bands and other bands. All the differences can only be explained on the basis of an ionic origin of the 2482 bands. The excited state of the molecular ion that emits 2482 bands is given evidence as that state resulted from a combination of a normal atomic ion and a neutral atom at the 3P1 excited state.

水银分子在2482A.U.左右有组光带,是水银分子伊洪的还是水银分子的这问题,我们用光谱强度的测量法解决了。将供作光源的通电管内的电流或水银气压依次的改变,我们发现2482A.U.光带的强度的改变和旁的已知的分子光带绝然不同。那些不同之点,只要引用“分子伊洪是2482光带的原主”这说法,就都明白了我们更进一步问放出2482光带的是那个高能力阶位理论和实验的结果指示出一个在最低能力阶位的原子伊洪(Hg~+)和一个在3P_1能力阶位的原子所结合成的分子伊洪是能放2482光带的高能力阶位。

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...

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。

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。
