The velocities of reaction of ethyl acetate with sodium hydroxide in dioxane- water mixture have been determined in seven different temperatures(5°,10°, 15°,20°,25°,30°and 35°).For each temperature,the compositions of solvent mixture are 0,5,10,15,20,25 and 30% of dioxane.We thus obtain 49 velo- city constants as summarized in the following table. At low temperatures,the velocity constant decreases slightly with decrease of dielectric constant of solvent.At higher temperatures,such decreases of k' become more pronounced. The“isocomposition”energy of activation decreases slightly with increase of percentage of dioxane in the solvent mixture. The“isodielectric”energy of activation shows practically no change,when the dielectric constant changes from 80 to 50.Its value is 11300 calories. The experimental data are compared with the three modern theories of ion- molecule reaction,namely,by(1)Moelwyn-Hughes,(2)Laidler and Eyring and (3)Amis and Jaffe.From the viewpoint of influence of dielectric constant on the rate of the present reaction,the first two theories disagree qualitatively with our experimental data,while the last one,though qualitatively successful,fails quantitatively.(The “enhanced moment” and index of refraction as calculated from the last theory with the use of our data are unreasonably large.)

作者在7具不同温度(5°,10°,15°,20°,25°,30°,35°)下,研究了乙酸乙酯和氢氧化钠在二氧六圜和水的混合溶剂中的反应速度。每个温度有7个不同的二氧六圜和水的成分(0%,5%,10%,15%,20%,25%,30%的二氧六圜),因此得到49个速度常数。在每个温度里,反应速度常数随溶剂介电常数的减小而略为下降:温度愈高,下降趋势愈为显著。同溶剂成分的活化能随着溶剂里二氧六圜成分的增加而略为下降。同介电常数的活化能,在80至50的介电常数范围中,却和介电常数的变化无关。它的平均值是11300卡。我们用实验结果检验最近三个溶液里离子和分子反应速度理论:(1)Moelwyn-Hughes 的、(2)Laidler-Eyring 的和(3)Amis-Jaffe 的理论。就介电常数对反应速度的影响来说,理论(1)和(2)在质上就不和实验相符。理论(3)在质上似和实验相符,但在量上却相差太远。因此就乙酸乙酯对氢氧化钠的反应来说,三个理论都是不合的。

An investigation of the rheological relationships between shear stress shear rate apparent bulk viscosity temperature was carried out by examining the viscous flow of slightly milled native Hevea rubber (i) The Eisenschitz's equation for non-Newtonian flow has been verified by the experiments on the dependence of shear rate on shear stress. By this equation, the apparent viscosity can be referred to the Newtonian viscosity η_0 (at σ=0). The parameter (G_i=3.30×10~5 dynes/cm~2), interpreted as an internal modulus of rigidity, was found to be practically independent of temperature in the range of 50-90℃, thus agreeing with the results by treating Saunder and Treloar's data. (ii) For the shear rate dependence of apparent viscosity, when the number of Khun segments per unit volume was taken into account for the calculation of retardation time τ_1=2.84η_0 [J_e]_∞, the Debye-Bueche's equation was found to be able to fit into our data at moderate low shear rates. The values of steady-state elastic compliance [J_e]_∞ were determined by elastic-recovery experiments. Furthermore, the internal shear modulus Gi could be thus calculated by combining the Eisenschitz's equation with the Debye-Bueche's one. (iii) From the experiments on the temperature dependence of viscous flow under various stresses, the apparent activation energy ΔE_η was found to be 12.7 kcal/mole; and therefrom, by estimation, the unit of flow-the Eyring segment would be 30 carbon atoms long. All determinations of the flow rate under constant stress were carried out in a Hppler parallel-plate plastometer, used as a viscoelasticity-rheometer according to the theory developed by Dienes.

In recent years, the geotectonic problem of China engages the attentionof many Chinese and Soviet geologists, but different opinions are confessed by different authors. After studying the structural characters of the fundamentalfloor and its later geological development, theauthor of this paper agrees withthe statement of the Soviet geologist, B. M. Синицын. In 1952 he pointed outthat the Chinese platform in eastern China, may bs divided into: (1) theSine-Korean platform; and (2) the Southern-Chinese platform, consolidatedas a result of the Luliang movement. This Chinese platform especially in its southern part shows a very peculiarphenomenon as it is called "Activization" of the platform. During Sinian andPaleozoic, its sediments belonged to the pronounced epi-continental type, duringthe mesozoic the south-eastern part of the Southern-Chinese platform wasneither a stable shelf nor a geosyncline, but an intermediate type between them.Its characters were really not geosynclinal, but sometimes showed geosynclinalaffinities, as for instances, the immense granitic intrusions, the eruptions oflavas, and the rather strongly folded geosynclinal structures. These imply thelimited mobility or the incomplete consolidation of the underground. Accor-dingly, referred to the structural type of this region, P. Misch called it"Sinotype". Furthermore, in the Southern-Chinese platform, two strong "Activizingunits" are recognized as follows: 1) The Hunan-Kwangsi activizing andsubsiding region; 2) The Cathaysian activizing oldland. The "Activization"of these regions lasted for a long geological time. It began in Sinian, throughCaledonian, Variscian, Indo-Sinian, Yenshanian and even Himalayan. BeforeMesozoic, the Caledonian was the most intensive and widely distributed one.But as pointed out by A. H. Мазарович, the Caledonian of the Southern-Chineseplatform was merely a fold-belt within the platform. According to its geotectonic history, its character of sedimentation, itsregional metamorphism, its igneous activity and its geotectonic systems, suchas "Kwangsi ∈ system", "North-Kwangtung ∈ system", "Meso and Neo-Cathaysiansystem", and the "Nanling eastwest tectonic zone", it is the author's opinionthat the "Imtermediate type (Sinotype)" of the Southern-Chinese platform wasdeveloped gradually through a long "Activizing process". This "Sinotype" is anintermediate type between the stable shelf and the geosynclinal region.

作者同意B.M.西尼村的意见,认为中国地台是中国东部的一个大的构造单位,它是在吕梁运动后造成的。中国地台由两个主要部分构成,它的北部称中朝地台,南部称华南地台。中国地台有一很重要的特征,就是一个“活化”的地台。华南地台的东南部“活化”尤其强烈而显著,在中生代的太平洋运动时,差不多具有类似地槽的特征。但是它的“活化”是有悠久历史的,即开始於震旦纪,所以加里东运动给与很大的影响,但加里东运动只是地台内部的褶皱。地台“活化”直到中生代太平洋运动才得到高度发展,产生巨大的火成活动以及“中国式”的构造型式。新生代时地台还有中等强度的运动和火成活动。自第四纪冰期之后,地台仍在较弱的升降运动中。华南地台无论从沉积岩相、区域变质及火成活动,或从山字型、华夏式及南岭东西褶皱的构造体系等构造型式发育史的研究,都可以看到它的“活化”过程,在这过程里发育了“过渡类型”的构造形态,这都是不同放地槽或地台的构造形态的。本文是作为学习心得性质的初步尝试,文中不成熟和谬误之处尚多,希望得到大家的指正。如果能在集体的讨论和研究之下将我国大地构造研究清楚的话,这是作者所衷心期望的。
