The absorption wavemeter investigated consists of a single loop with a variable gap which is formed by a pair of parallel plates. A calibration formula for the meter was derived on the assumption that the stray capacity could be considered constant and the stray inductance negligible. This simple and useful formula was ex perimentally checked on four different meters, covering the range from about one-and-quarter meter to one-half meter. These melors were carefully constructed and accurately calibrated with...

The absorption wavemeter investigated consists of a single loop with a variable gap which is formed by a pair of parallel plates. A calibration formula for the meter was derived on the assumption that the stray capacity could be considered constant and the stray inductance negligible. This simple and useful formula was ex perimentally checked on four different meters, covering the range from about one-and-quarter meter to one-half meter. These melors were carefully constructed and accurately calibrated with reference to a quartz oscillator by the double-heating method through the use of an auxiliary oscillator of a continuous range of wave-lengths from six to ten meters.

吸收式波长计之理论上,以其杂储电量为常数而略其杂磁感量,得一简便之公式虽在波长一公尺左右亦可用。所研究之吸收式波长计之构造,系一黄铜制成之单圈,用二黄铜片制成之一缝隙。其缝隙之宽度,可由一螺旋调节。此种波长计,曾 在国立中央研究院物理研究所制造室制造四具,可量波长一有四分之一公尺至半公尺亦曾在此研究所之实验室内,与水晶振荡器校准先制一振荡器,可在六至十公尺之间,发生无论任何波长之振荡。并将此振荡器与一水晶振荡器用拍谐法校准。再制一有四分之一公尺至半公尺之振荡器,与已与水晶校准之振荡器,再用拍谐法校准,而同时以所制之吸收式波长计量之其实验与理论所得之各结果极为符合。

The absorption band of water vapor at 0.94 μ is studied photographically by means of a concave grating spectrometer. Twenty eight component lines are observed and measured on a comparator as well as on a Moll microphotometer. This band shows something of a doublet form which suggests that the H2O molecule has a triangular form with the oxygen atom at the vertex of an obtuse angle. The lines agree closely with some of the absorption lines in the solar spectrum as measured by Abney in 1880.

前之研究红外光谱者类多依赖热电堆以测定光谱内光能之分布。吾人咸知红外带状光谱之接近可见部分者,其成分线排列甚密。若用热电堆万难分析而得其细微组织。作者所考察之光谱正在红外照相片感光范围之内,故得测定水汽带状光谱内各成分线之波长而具有1内之准确度。 作者所用分光仪器为一凹面光栅,其曲度半径为2公尺。该光栅面上每厘米划有线6000根,颇适合红外光谱之探讨。所用光源为一1000流明之电灯泡泡内有一一字形线圈灯丝,其所发之光穿过2公尺之105°—110℃水汽而交聚在分光仪之缝上。红外照相片经氨溶液之超度敏化后,即安置於已经配准之相片匣内,而使之感光。光之可见部分系用深红滤片割除。照光时间约 费四五十小时,然后除去滤片,照以水银光谱凡数秒,作为决定波长之标准。 用前法所摄得之光谱大都不十分清晰,其主要原因系由水汽管之太短。但用显微光度计量之,各成分线之波长不难准至1(?)范围以内。本实验所得各线若与五十年前Abney所测定太阳光谱中0.94μ附近之吸收线相比较,可见太阳红外光谱中许多吸收线系由大气中水汽所产生,而证实Abney最初之推想。惟本实验所测定之吸收线与Abney所测定太阳光...

By surrounding a photo-neutron source of Ra+Ee with a thin spherical sbell of paraffin, a continuous spectrum of scattered neutrons, extending from zero energy to the energies of the primary neutrons is obtained. When a silver detector is exposed to such a spectrum, a part of the neutrons having just the energies at resonance with the silver nuclei is strongly absorbed by the detector and thereby produces the induced β-activity.

By surrounding a photo-neutron source of Ra+Ee with a thin spherical sbell of paraffin, a continuous spectrum of scattered neutrons, extending from zero energy to the energies of the primary neutrons is obtained. When a silver detector is exposed to such a spectrum, a part of the neutrons having just the energies at resonance with the silver nuclei is strongly absorbed by the detector and thereby produces the induced β-activity. By measuring the activity of silver and the apparent absorption coefficient of the resonance neutrons in a thin silver absorber, the total width of the resonance levels effective to neutron capture and located in the above spectrum is estimated. Let τ He the average value of one half of the half-value width of the resonance levels, expressed in volts, and n be the number of resonance levels here concerned. We find nτ=260 volts for the silver nuclei of half period 22" if the energies of the primary neutrons are taken to be 2x 105 volts. Knowing nτ, we can evaluate the average spacing between adjacent resonance levels effective to neutron capture by giving a plausible value to τ. We find a spacing of the order 80-800 volts if τ be given the value 0.1-1.0 volt. This result is in good accord with the recent theoretical calculation of Bethe and also with observations of resonance groups in the low energy region.

把‘镭—铍’所产生的‘光中子’,穿过一层半厘米厚的白蜡,我们便得到一‘连续的中子谱’。他们中间有些中子,能和银的原子核起‘共振作用’,因此可以被银片吸收,而产生‘人工放射银’先测量人工放射的强度和‘共振中子’在银片中的吸收率,再应用原子核内共振能层的宽度,我们便可以求出银的原子核内‘共振能层’的密度大约共振能在零和二十万伏特中间,平均每隔一二百伏特便有一可以吸收质子的共振能层,和理论很相符合。
