无蹼壁虎消化道组织学及组化观察初报

Ｃａｒｎｏｙ固定,常规石蜡包埋、切片、Ｈ．Ｅ染色、ＰＡＳ反应、ＲＮＡ反应,对无蹼壁虎消化道的组织学进行光镜观察．结果表明：其消化道由同心圆的粘膜层、粘膜下层、肌层和浆膜层组成．绒毛发达,绒毛的上皮细胞为单层柱状上皮．消化腺为分枝管状腺．ＰＡＳ反应显示柱状细胞纹状缘,杯状细胞和腺细胞呈强阳性,与分泌的粘多糖有关．ＲＮＡ反应显示腺细胞呈强阳性,与腺细胞分泌活动有关．     

羧酸在油水相中的分布

研究了甲酸和乙酸于水中和不同有机介质中的分配系数,重点研究了含21、24和27碳原子的三烷基叔胺对甲酸和乙酸的成盐萃取作用。同时,在不同稀释剂及其用量、温度以及甲酸和乙酸浓度的条件下,确定了小分子羧酸的分配系数及其变化规律,最后,根据有机羧酸叔胺盐的热分解行为获得了纯度达90％的甲酸和乙酸,从而为重有机工业的酸回收提供了工艺技术设计的依据。

A continuous 200-ka palaeoclimatic record from stalagmite in Tangshan Cave, Nanjing

An oxygen isotope temperature record from 381 to 166 kaB. P. (²³⁰Th/²³⁴U dating and tuned ages) has been obtained by combining data on the isotopic composition of calcites with that of fluid inclusions trapped in a stalagmite from a limestone cave in which a fossil cranium deposited. Several laminae in microsequence of the stalagmite represent climatic events or shifts. The Nanjing man fossil was older than 381 kaB. P.     

The Juancheng chondrite──A new meteorite falling recently in China

The Juancheng chondrite, a new meteorite falling recently in Juancheng County, Shandong Province, China, is classified as an H5 (S2) chondrite based on the compositions of olivine (Fa= 19.2, σ Fa=0.46) and low-Ca pyroxene (Fs=16.9, σ Fa=0.4). The plagioclase in the Juancheng chondrite is rich in CaO, indicating a relatively high metamorphic temperature the parent body underwent.     

Discovery of eclogite at northern margin of Qaidam Basin, NW China

Eclogite was first discovered at the northern margin of the Qaidam Basin in this study. It occurs as pods in the gneiss sequence of Middle to Upper Proterozoic age and is mainly composed of garnet, omphacite, phengite and rutile. The garnets contain 44%-62% of almandine, 15%-33% of grossular and 12%-30% of pyrope molecules, and the omphacites contain 40%-46% of jadeite. Applying garnet_clinopyroxene thermometry and jadeite geobarometry, the peak conditions of eclogite facies metamorphism occurred at about (722±123)℃ and at the pressure of up to c. 22 ×10 8 Pa.
