In this note, a simple but not rigorous proof for dispersive relations is given. The proof proceeds by expanding the causal amplitude with respect to the intermediate states and considering the analyticity of the energy denominator and the corresponding numerator separately. While the analyticity of the energy denominator is more or less obvious, the proof of the analyticity of the numerator, say 2V, is achieved by considering the analyticity of the corresponding numerator where the mass μ2 has been replaced...

In this note, a simple but not rigorous proof for dispersive relations is given. The proof proceeds by expanding the causal amplitude with respect to the intermediate states and considering the analyticity of the energy denominator and the corresponding numerator separately. While the analyticity of the energy denominator is more or less obvious, the proof of the analyticity of the numerator, say 2V, is achieved by considering the analyticity of the corresponding numerator where the mass μ2 has been replaced by -p2 (μ = mass of meson, p = momentum of nucleon in Breit's system, the scattering of mesons by nuc-leons being considered for definiteness) and passing to the analyticity of N with the help of a suitable transformation. The idea of replacing μ2 by another quantity is due Bokolubof (BorOJlK)60B), but here analyticity with respect to this new quantity is not considered. In the present method, p2 is allowed to be as great as M2 -μ2 (M = mass of nucleon).

在此短文中,我们给色散关系一个简单的但不严格的证明。证明的方法为将因果振幅对中间态展开,分别研究能量分母及相应的分子的解析性。能量分母的解析性是较显然的。至于分子的解析性的证明,我们先研究μ~2换为—p~2时的相应量(μ为介子质量,p为核子在Breit坐标系中的动量,介子核子散射为我们所考虑的具体对象),研究其解析性,通过一个变数的变换而达到我们证明的目的。在此方法中,p~2可以大至M~2—μ~2,M为核子质量。 我们也考虑了在位场散射中相位移η(k)的解析开拓问题,证明了如果位能在r→∞处形如e~(-αr)(a>0),则η(k)可以开拓至|Imk|<_2~1α的区域。

A possible integral representation of double commutators allowing non-vanishing mass of intermediate states is obtained. As expected, it reduces to Dyson's result on putting the masses to be zero. A discussion is also given showing how dispersive relatsions for non-forward scattering can be obtained on assuming the fourier transform F(q0, q) of the

在中间态最低质量不为零的情形下,求出了双交换子的积分表示的一个可能形式。在最低质量取为零时,它化为Dyson的结果。 又讨论了如何简单地自积分表示求出色散关系。

Metallographic observations were made on mixed copper-iron whiskers grown by reducing chlorides of these metals together in hydrogen. The layer structure of a section of the lower part of a whisker was found to be different from that of its upper part. In addition to growing in layers, mixed whiskers also showed the peculiarity of growing in segments. When the growth in layers and in segments were considered in a unified view, a mechanism of growth was suggested in which an alternation of one-dimensional and two-dimentional growth was assumed to proceed continuously in the course of growth. Mixed whiskers of more than two metals were also grown; it was found that the growth in layers was much more obvious. Hardness measurements on cross-sections of the whiskers showed that the hardness is different at different places. The behavior of such whiskers was shown to be analogous to that of concrete reinfored with steel, in which the axle whisker plays the role of steel and the surrounding dispersive mixture plays the role of concrete.

把氯化亚铜和氯化亚铁一起在氢气中进行还原,得到了混合铜铁须。对于这种金属须进行金相观测时发现,金属须下部的一个截面里所呈现的层状桔构与金属须上部的一个截面里的不同。混合金属须除了表现层状生长以外,还表现了特殊形式分段生长。用综合的观点来考虑层状生长和分段生长,提出了一个混合金属须生长机构,在其中假定了在生长过程中不断发生一维和二维生长的相互更迭。也生出了二种以上金属的混合金属须,在这种金属须中的层状生长更为明显。在金属须的截面上进行了微硬度测量,指出在不同地点的硬度并不相同。混合金属须的行为有点象是钢筋混凝土,它中部的心轴金属须有如钢筋,而四围的瀰散混合体有如混凝土。
