Estradiol method for estrogen receptors by ~3H-estradiol has been used almost routinely, but application of fluorescein-labeled derivative of estradiol are only at outset. Dandliker has synthesized such a conjugate by condensing 1,3,5, [10]-estratriene-3, 17β-diol-6-iminooxyacetic acid with fluorescein amine. He found that this conjugate binds E, receptor or antibody, thus changing its fluorescent polarization. However,

Previous investigations showed that the resistivity of amorphous alloys is generally very high. Its temperature coefficient is remarkably small. The resistivity minimum phenomenon not only may appear in dilute alloy of magnetic impttries but also can coexist with ferromagnetism. In amorphous alloys although several theoretical models have been proposed explanation of the resistivity anomalies has been a subject of controversy.

作者：过乃蓉罗庆尧陈震华曾云鹗 Department of Chemistry Wuhan University Department of Chemistry Wuhan University. INTRODUCTION Recently the utilization of the chelating properties of triphenylmethane dyes in the presence of surfactants for speetrophotometric determination of rare earth ions has received a great deal of attention. Those systems which are generally much more sensitive than similar reactions in the absence of surfactants are not satisfactory in selectivity as reactions are produced in neutral or weak acidic solution.

作者：倪向善陈润生 Institute of Biophysics Academia Sinica Beijing Institute of Biophysics Academia Sinica Beijing model of protein synthesis in an oosperm was put forward by Chen Runsheng where all the molecules of aminoacid and protein were considered as spherical ones. In this paper the case where they are all ellipsoids of revolution is considered but the rotation of the molecules during diffusion is not taken into account. Also the hypothesis of dilute solution is used. Since the cleavage of the first time may take place at any stage of evolution and uncertainly do at the time when the steady state is reached solving directly the dynamic partial differential equations will contribute to the acquirement of some fundamental ideas of the whole process of protein synthesis in an oosperm.
