PRELIMINARY STUDY ON FEMALE REPRODUCTIVE SYSTEM OF Chiloscyllium plagiosum (Bennett)

条纹斑竹鲨为小型体内受精、卵生种类 ,是闽南近海常见鲨类。其雌鱼仅具右侧卵巢 ,呈葡萄状裸露型 ,怀卵量约二三百个 ,卵细胞不同步发育 ,成熟卵径为20～30mm ,卵中含大量卵黄。条纹斑竹鲨卵壳腺的大小随鱼体的生长而增大 ,达到性成熟时约80mm×50mm。卵经过卵壳腺时受精 ,受精卵外被一厚而坚韧的卵鞘 ,为黄褐色、椭圆四角形Chiloscyllium plagiosum is a kind of small oviparous shark and can be collected in south of Fujian waters all the year.The female has two ovries:the left one and the right one.And only the right one lays 200～300 eggs at different stages.The Eggs' size at ovulation is 20 ～30 mm in diameter, with rich yolk. The size of the oviducal gland increases as the fish body gets bigger and is about 80 mm×50 mm at the sex mature stage. The ova may be fertilized at oviducal gland and then the thick brown rectangle egg case forms is formed.福建省自然科学基金资助项目9810005

Studies on Catalytic Mechanism of Li/SOCl_2 Batteries by Metal Phthalocyanine Complexes

合成过渡金属酞菁配合物MPc(M=Mn(Ⅱ),Fe(Ⅱ),Co(Ⅱ),N i(Ⅱ),Cu(Ⅱ)),研究MPc及其中心离子对L i/SOC l2电池正极的催化作用,并提出相关催化机理.Effects of metal phthalocyanine comlexes MPc(M= Mn(Ⅱ),Fe(Ⅱ),Co(Ⅱ),Ni(Ⅱ),Cu(Ⅱ)) as electrochemical catalysts on the performance of Li/SOCl2 batteries have been examined at constant resistance.And the reasons of MPc affecting the discharged voltage and discharged time of Li/SOCl2 batteries were also brought forward.A few new viewpoints on the catalytic mechanism of the reduction of thionyl chloride by phthalocyanine complexes were proposed.作者联系地址：西北大学化学系陕西省物理无机化学重点实验室,西北大学化学系陕西省物理无机化学重点实验室,西北大学化学系陕西省物理无机化学重点实验室,西北大学化学系陕西省物理无机化学重点实验室,西北大学化学系陕西省物理无机化学重点实验室,西安机电信息研究所,西北大学化学系陕西省物理无机化学重点实验室 陕西西安710069,陕西西安710069,陕西西安710069,陕西西安710069,陕西西安710069,陕西西安710065,陕西西安710069Author's Address: 1.Shaanxi Key Laboratory of Physico-Inorganic Chemistry,Department of Chemistry, Northwest University,Xi'an,710069,China,2.P.O.Box 121,Xi'an,710065,Chin
