Measurement of the intensity of total scattering of x-rays by a number of polyatomic gases was made for scattering angles between 15° and 130 ° using an ionization method of recording the scattered intensity. Balanced filters of ZrO2, and SrO were used to separate the MoKa rays and Soller slits were placed in front of the ionization chamber to obtain a definite scattering angle. The gases studied are CL2, CO2, N2O, H2S, CC14 and CHCl3. In each case the absolute values of the scattered intensity were determined...

Measurement of the intensity of total scattering of x-rays by a number of polyatomic gases was made for scattering angles between 15° and 130 ° using an ionization method of recording the scattered intensity. Balanced filters of ZrO2, and SrO were used to separate the MoKa rays and Soller slits were placed in front of the ionization chamber to obtain a definite scattering angle. The gases studied are CL2, CO2, N2O, H2S, CC14 and CHCl3. In each case the absolute values of the scattered intensity were determined by comparison with the scattering from oxygen, the results of Wollan for the latter gas being taken as correct. The experimental results are actually compared with Woo's theory of the scattering of x-rays by polyatomic gases and the agreement seems to be satisfactory.

吴有训氏最近对于多原子气体散射线之理论,曾作详尽的探讨。吴氏得到一个公式,表示由多原子气体所散射之强度,其中一部为相干的散射,另一部为不相干的散射。 以前关于多原子气体散射X-线之实验,为数甚少,且为定性的结果。最近美人Wollan,对于由O_2及N_2(双原子气体)所散射钼的K_3α线之强度,曾作绝对的度量。Wollan的结果,与吴有训氏的理论,甚属相符。本篇目的,在测定由 Cl_2,CO_2,N_2O,H_2S,CCl_4及 CHCl六种气体所散射X-线之强度,每一实验,均与由0_2者互相比较,根据Wollan的结果,每种气体所散射之绝对强度,皆一一量得。所用之入射X-线为钼之Kα线,系藉Ross的平衡过滤法分出。强度之测量,系用一游离方法。散射角度的范围,自15度至130度。每种气体的实验结果,均与吴氏的理论,互相比较,证明理论与实验,甚属相符。在计算时,原子的“构造因数”,系由Hartree的方法算得,一分子中两原子的相隔距离,则由带光谱的结果推得。

1. All kinds of colonies of Volvox africanus were found in great abundance during the first two weeks of May, 1933, from a pond in Nanking.2. The smallest colony is much smaller than that recorded from Africa and the Philippine Islands.3. The somatic cells are not connected by protoplasmic filaments in adult colonies.4. Asexual colony usually contains from two to six daughters symmetrically arranged in pairs according to size on opposite sides of the polar axis.5. Sexual colonies of different kinds are developed from the asexual mother either singly or in combination with other kinds and asexual daughters.6. Parthenogonidia develope very early in young embryos long before the latter become matured and escaped from the mother colony. 7. During the early development of parthenogonidia, at least from first to fifth or sixth divisions, no growth of the whole embryo takes the place while the number of cells increases.8. Spermatogonia attain fully-grown size and begin to divide before the time of the birth of the colony.9. The development of spermatogonium consists of seven successive divisions in forming a bundle or platelet of one hundred and twenty eight spermatozoa or microgametes.10. The number of ovaries in a female colony varies from twelve to fourty six. Generally, the larger the colony, the more the ovaries developed.11. Risexual colonies contain only two or three spermatogonia in addition to fourteen to twenty seven ovaries.12. In general, specimens recorded in Nanking are identical to those from the tropical regions such as Africa and the Philippine Islands.

關於菲洲團走子之分佈,按記載所及。僅限於菲洲,菲列濱,南印度等熱带區域。今在南京發現,於地理分佈上實為一新記錄。此種團走子在羣體成熟之後,其體質细胞間,並無原生質線交相聯絡。無性羣體每含有二至六大小不同成對均置之無性幼羣體。幼羣體在脫離母體以前,往往含有第二代幼體。各種有性羣體,亦自無性母羣體中發達而成。雄性羣體,皆为橢圓形,而較其他羣體為小。雌性羣體中之卵或大配子约有十二至四十六。雙性羣體只含有二或三精原细胞,及十五至二十七卵或大配子。孤性生殖细胞在幼羣體内即發生。當最初五或六次分裂時,细胞雖增加,而幼胎並不長大。精原细胞经七次連續之均等分裂,而成一束一百二十八精子或小配子。

An attempt to observe the spectrum of doubly excited helium by excitation by electron impact, with energies between 500-600 electron volts, is made without success. This and other failures are discussed by considering of the life times of the doubly excited states. An approximate calculation gives for 2s3s3S a life time of the order 10-15 sec, corresponding to a natural width of the level of the order 1000 cm-1. While this accounts for the absence of a line spectrum of doubly excited helium, it renders the former...

An attempt to observe the spectrum of doubly excited helium by excitation by electron impact, with energies between 500-600 electron volts, is made without success. This and other failures are discussed by considering of the life times of the doubly excited states. An approximate calculation gives for 2s3s3S a life time of the order 10-15 sec, corresponding to a natural width of the level of the order 1000 cm-1. While this accounts for the absence of a line spectrum of doubly excited helium, it renders the former suggestion that the corona lines may be due to it untenable.

(1)日晕光谱线之来源,至今为未决定之问题。Goudsmit与吴大猷曾假设诸谱线乃由氦气双激起原子所生。过去有人企图用实验方法得到双激起氦原子之光谱,未能成功。但有数种实验室内现象,均有人用此假设以解释之。故作者希望在适当情形下得到双激起氦原子之光谱。 (2)由理论上知用电子撞击法造成双激起之可能性甚小,但此可能性之最大值在电子能为300至600electron volts时故作者企图在人为的此种情形下观察双激起氦原子光谱,但结果未能发现。 (3)此种实验结果可从理论方面予以解释。作者由双激起2s3s~3S状态之计算,知其谱线之宽约为1000cm~(-1),故实验时不能观察因此以前关於日晕光谱之解释,亦成疑问。
