  theory
We use the theory of tilting modules for algebraic groups to propose a characteristic free approach to "Howe duality" in the exterior algebra.
      
This study was continued in the paper [FKRW] in the framework of vertex algebra theory.
      
As in the case of Mumford's geometric invariant theory (which concerns projective good quotients) the problem can be reduced to the case of an action of a torus.
      
We also show how to distinguish examples of open subsets with a good quotient coming from Mumford's theory and give examples of open subsets with non-quasi-projective quotients.
      
The theory is applied to the case of cubic hypersurfaces, which is the one most relevant to special geometry, obtaining the solution of the two classification problems and the description of the corresponding homogeneous special K?hler manifolds.

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。

In this paper the writer employs complex Riemannian Geometry and defines the absolute interval between two points as consisting of a real part and an imaginary part. Two postulates (I) and (II) are used: the first may be called law of gravitation and electro-magnetism; the second equation of motion. In the absence of electromagnetic phenomena the theory reduces practically to Einstein's theory.

在此文内,作者利用复变来曼几何以宇宙间两点之距离为一实数及一虚数部分相构而成,於此并用假说:一可称为吸力及电磁定律,一为物体行动定律,解释吸力及电磁力之各种现象。在无电磁现象时,此文与爱因斯坦之吸力理论多相符合至於详细情形,容诸续篇。

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.

在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。
