芝罘群岩石地层划分及区域对比

芝罘群分布于烟台市区北部芝罘岛、崆峒岛、担子岛等岛屿上,自下而上划分为老爷山组、兵营组及东口组.东口组为新建岩石地层单位.该群岩石组合为白云母钾长片麻岩、含电气石钾长石英岩、钾长石英岩、镜铁矿钾长石英岩、石英岩、白云母石英片岩夹黑云片岩、透辉变粒岩及大理岩等.其原岩为富钾、铁、硼的长英质碎屑岩夹粘土岩及富镁碳酸盐岩.兵营组单颗粒锆石U-Pb年龄为2171Ma,其成岩时代属古元古代早期.芝罘群区域上可与辽东地区古元古代榆树砬子群对比.     

胶南造山带西段区域构造格局及变形特征

胶南造山带西段显示了以韧性剪切带为主，穹隆构造、弧形构造及复杂的叠加褶皱共存的构造格局。主要的剪切系统有近水平拆离型、平行造山带走向的高角度走滑型、呈弧形展布的推覆型和造山带边缘隆－滑型韧性剪切带。走滑型剪切带是该区变形最明显的一组强剪切应变带，其运动性质以右行平移为主；弧形韧性剪切带由垂直造山带走向的近南北向转为平行造山带走向的近东西向，呈向NW凸出的弧形，自SEE向NWW方向推覆；造山带边缘韧性剪切带具明显的纵向分段性，反映了其在隆升的同时形成了垂直造山带和平行造山带的运动分量。主要的穹隆构造有尚庄穹隆、丝山穹隆、甲子山穹隆和官山穹隆。尚庄穹隆由片麻理围斜外倾、环形韧性剪切带及环状分布的包体群所显示，是岩浆强力定位造成的真正的片麻岩穹隆。弧形构造主要有龙古弧、诗雒弧和临沐弧，它们显示了胶南造山带三维空间上的“立交桥”式结构特征。     

TRANSFERABLE PHOSPHORUS IN SEDIMENTS OF THE HUANGHE RIVER ESTUARY ＇S ADJACENT WATERS

Based on a new idea for research on cycling of marine biogenic elements, this study showed that only the leachable form phosphorus in natural grain sizes manne sediments constitutes the transferable phosphorous in the sediments. The transferable phosphorus content in the natural grain sizes surface sediments in the Huanghe River estuary adjacent waters ranges from 58.5-69.8 μg/g, accounting for only 9.1%-11.0% of the total phosphorus content, whereas the leachable form (“transferable” )phosphorus content in the sediment after it was totally ground into powder was found to be 454.8-529.2μg/g, accounting for 73.4%-89.1% of the total phosphorus. Analysis of the correlation between thebill,ass of benthos and the leachable form (“transferable” ) phosphorus showed that most of the leachableform (“transferable”) phosphorus in the totally ground sediment did not participate in the marine biogeo chemical cycling. Furthermore, a synchronous survey on benthos showed that the biornass of meio-and maero-benthos exhibited good positive correlation with the leachable form of phosphorus in the naturalgrain sizes sediment, but peorer correlation with the leachable form (“transferable”) phosphorus in the totally ground sediment, indicating that transferable phosphorus in marine sediment is the leachable form of phosphorus in the natural grain sizes sediments, and is not the previously known leachable form(“transferable”) phosphorus obtained from the totally ground sediment.     

脉冲星γ射线辐射光度的分析

本文作者在脉冲星γ射线辐射的极冠模型的基础上，考虑光子在磁层中的级联过程，提出了级联过程中能量转化效率的概念并得出了转化效率公式，分析表明，能量转化效率只和磁场强度有关，与周期无关，考虑能量转化效率，我们计算了极冠模型的γ射线辐射光度，得出了可以和观测值比较的结果，本文结果倾向于支持脉冲星γ射线辐射的极冠模型。     

ESTIMATION OF SOUNDING ABILITY OF A BRILLOUIN LIDAR IN THE EAST CHINA SEA

Vertical profiles of sound speed in the sea can be measured by using laser excited Brillouin scattering. In this paper the dependence of the accuracy of sound speed measurement on the accuracy of the Brillouin shift measurement is analyzed. We calculated the maximum detecting depths of sound speed to an accuracy of 1 m/s by lidar with different laser pulse energy, platform altitude, telescope aperture and lidar effective attenuation coefficient. The estimation of sounding ability in the East China Sea is made in some stations. These data can be used in the design of Brillouin Lidar for the China Sea.     

贵州与印度的夏季风的异同分析

季风作了气象科学的一个重要课题，许多人都作了大量研究，中国和印度均处于季风区，印度季风和中国季风的研究已作了大量研究，揭露了不少事实，但中国季风的研究多指我国的东部，而贵州位于我国西南部，地处东亚季风和印度季风之间的过渡区，因此，对贵州省的论及较少，从气候的角度出发，把贵州和印度的季风的某些特征量，如降雨、风、环流等进行对比分析，在一定程度上反映了贵州和印度夏季风的主要异同。     

Acute toxicities of potassium permanganate, formalin, and Lugol’s iodine solution to a marine ciliate, Pleuronema coronatum (ciliophora, scuticociliatida)

Acute toxicities of potassium permanganate, formalin, and Lugol’s iodine solution to a commonly occurred marine ciliate Pleuronema coronatum (Ciliophora, Scuticociliatida) were measured. Linear regression analysis of the results highlighted the close relationships between doses of the medicines and mortalities of the organisms, thus providing a capability to predict toxicity effects from the dose. Toxic effects of the medicines on the ciliates were described in the present paper, and the median lethal concentrations (LC₅₀ values) were given. Results of measurements indicated that 2 h-LC₅₀ and 12 h-LC₅₀ values of formalin on P. coronatum were 59.00×10⁻⁶ and 43.57×10⁻⁶, while those of Lugol’s solutions were 90.13 and 67.84×10⁻⁶ respectively. The tolerance of P. coronatum to formalin is apparently lower than that to Lugol’s iodine solution and potassium permanganate is a suitable medicine to kill ciliates in short time.     

Grain-size related nitrogen distribution in southern Yellow Sea surface sediments

Forty-eight surface sediments of the southern Yellow Sea are separated into three grain-size fractions. Four forms of extractable nitrogen (nitrogen in ion-exchangeable form (Nie), nitrogen in weak-acid extractable form (Nwa), nitrogen in strong-alkali extractable form (Nsa) and nitrogen in strong-oxidant form (N50))are obtained by the sequential extraction. The results show that the contents and the distributions of the extractable nitrogen in the southern Yellow Sea surface sediments are closely related to sediment grain size. The distributions ofNie, Nso and total nitrogen (TN) present positive correlations with fine particles content, while Nwa and Nsa does not have such correlation. The net contents of all the forms of nitrogen increase with sediment grain size finer.
