割水晶成一圆柱,圆柱之轴即为晶体之光轴,在圆柱之中心穿一孔道,使成一空心圆柱壳,以金属箔敷於圆柱壳内外侧面成两电极。当圆柱之一端固定,一端被扭,则两电极发生异号而等量之电荷,扭转之方向既易,内外两极电荷之号亦互易。若扭力偶矩左旋,则左旋水晶柱之外极得正电;若扭力偶矩右旋则右旋水晶柱之外极得正电。 吾人曾由实验测定水晶圆柱之长短l,内外直径d_i及d_0之大小,与由扭偶矩C所生电量q之关系式如次: q=k(l/(d_0(d_0-d_i)))C式中K为一常数,在C.G.S.绝对静电单位制中等於9.2×10~(-8)。

The present paper gives a preliminary report on the fine structure of the trophozoites of Entarnoeba moshkovskii.The organism was fixed for a period of 5-10 minutes in 1% OsO_4 in veronal buffer,dehydrated by successively in- creasing concentrations of ethanol and embedded in a standard methacrylate mixture.Sections were cut at about 250 A and examined with the 100 electron microscope. The plasma membrane of E.moshkovskii may have different appearances according to the activity of the organism at the time of fixation. It may show a double membrane in “sandwich-like” configuration,and in an adequate section,as shown in Fig.3(PL),the plasmalemma bears on its outer surface a fine,closely-packed and feather-like fringe.The cytoplasm is alveolar in structure with a wide distribution of endoplasmic reticulum.Vacuoles of varying sizes,with inges- ted rice starch and/or partly digested bacteria (Fig.1,FV),are found mostly in the endoplasm. The membrane of these vacuoles appears identical with the plasma membrane.As shown in the electronmicrograph of osmium-fixed specimens, the cytoplasm reveals clearly an electron-dense, vacuolated endoplasm which is in contrast to the reticulated ectoplasm of low density(Fig.2). The finely granulated nucleoplasm is character- ized by its greater electron density than the cytoplasm.An irregularly shaped dense area composed of fine particles(Fig.1,4,K)is the nucleolus as revealed by the electron microscope, but it does not have any definite shape such as can be observed by light microscopy.The nuclear envelope in certain sections is shown to have a double membrane separated by a narrow area of low density.Corresponding to the “beaded” areas within the nuclear membrane as seen in light microscopy,large irregularly shaped electron densities composed chiefly of fine particles are observed at the periphery of the nucleus.The electron dense “beaded”areas,i.e.the concentra- tion of fine particles,are evenly distributed at the inner rim of the nuclear membrane and are covered by countable chromatin granules of grea- ter size and higher electron density. In the cOurse of the present study,attention has been given to the appearance of food vacuoles constantly distributed in the midst of the “nuclear cloud”that encircles the nucleus.Furthermore, all these food vacuoles are enveloped at their outer rim by the electron-dense particles radiating from the nucleus.Discussion is made with refer- ence to Hopkins'(1946)opinion regarding the physiology of digestion of E.histolytica.

本文对莫氏内阿米巴的细微结构作了电子显微镜的观察和研究。在以200~300 A 薄切片、经以100型电子显微镜观察,看到虫体细胞质系由双层结构的浆膜包被;细胞的内外质区分显著,内质含有许多空泡与食物泡,以及内质纲与核糖蛋白颗粒;外质则为均匀的纲状结构。细胞核主要包括由电子密度较高的细微颗粒所组成的致密核质和其外表双层结构的核膜;核膜内缘有电子密度较高的、念珠状排列的密集区,复盖在密集区上还有大型颗粒和集聚颗粒;核仁在核的中央,或偏位,没有恒定的形状。本文结合 Hopkins 等的观点,对莫氏内阿米巴的消化过程作了简单的讨论。

The purpose of this paper is to describe some spicies of Sycidiales collected fromYunnan,Guizhou,Hunan,Sichuan and Xizang.The collections contain 4 speciesof Sycidium and 1 species of Chovanella,of which Chovanella is for the firsttime reported in China.The Charophyte-bearing deposits may be assignable to theMiddle Devonian Donggangling stage,corresponding to the Givetian stage in Europe.Peck(1934)believed that 18 meridional units on the lime-shell of Sycidium were for-med by vertical division of 9 original...

The purpose of this paper is to describe some spicies of Sycidiales collected fromYunnan,Guizhou,Hunan,Sichuan and Xizang.The collections contain 4 speciesof Sycidium and 1 species of Chovanella,of which Chovanella is for the firsttime reported in China.The Charophyte-bearing deposits may be assignable to theMiddle Devonian Donggangling stage,corresponding to the Givetian stage in Europe.Peck(1934)believed that 18 meridional units on the lime-shell of Sycidium were for-med by vertical division of 9 original cells budded from the outer surface of thenode-cell.However,the well-preserved specimens under study indicate that aroundthe basal orifice there exist only 8 cells and that the manner of cell division isobviously much more complicated.In Sycidium,one of the characteristic features isthe polygonal reticulate pattern on the lime-shell,which was first recognized by Con-kin et al.(1972)on the cast of oosphere of Sycidium foveatum Peck.The discoveryof similar pattern on the cast of oosphere of Sycidium anhuaense sp.nov.,affordsan additional evidence for the suggestion that the lime-shell of Sycidium is a truegyrogonite instead of being a utricle.

本文描述了中泥盆世的直立轮藻5种、1型,分别属于Sycidium 和Chovanella 两属。文中讨论了这两个属的分类位置问题,详细阐述了Sycidium 藏卵器的发育特点,提出了关于藏卵器包围细胞分裂发育过程的新认识,同时提出了含化石地层的时代应相当于中泥盆世晚期的吉维特期。
