血清金属元素含量与缺血性脑血管病相互关系探讨

对缺血性脑血管病（ＩＣＶＤ）患者血清Ｚｎ、Ｃｕ、Ｃｒ、Ｍｇ元素进行测定,结果表明患者血清Ｃｕ、Ｃｒ、Ｍｇ含量比对照组低,Ｚｎ含量和Ｚｎ／Ｃｕ比值比对照组高,测定患者Ｚｎ／Ｃｕ比值较测定单一元素Ｚｎ、Ｃｕ更有意义。     

金属薄膜中的电导率计算

考虑到杂质和表面粗糙的散射,运用量子统计的格林函数方法,计算金属薄膜中的电导率．计算表明：在薄膜系统中,来自杂质和表面粗糙散射的电导率都以π／ｋＦ（ｋＦ为费米波矢值）为周期随厚度ｄ振荡．

Observational study of the circulation in the southern South China Sea

CTD data from two oceanographic survey cruises, conducted by “Shiyan No. 3” R/V during two reversing monsoons, were employed to calculate and analyze the distributions of temperature, salinity and geopotential anomaly in the southern South China Sea (SSCS). Based on these distributions, the horizontal structures of the SSCS circulation are described systematically. Study results show that the SSCS circulation structure could be classified as a two-layer (the upper and the lower) pattern, and that the main circulation in the upper layer (0–400 m) is driven by the South China Sea monsoons and is opposite in direction to the reversal of the monsoons. The distributions of principal current systems and their features are presented. Two important local phenomena, local eddy and oceanic front, were observed.     

Buckling of a ferromagnetic thin plate in a transverse static magnetic field

An energy theory is proposed on the buckling of a ferromagnetic thin plate in a transverse static magnetic field. The analytic solution of critical field for plates is obtained by using variational method. It is shown that the critical magnetic field is not only influenced by the ratio of the thickness to the length, but also by the width, total length and the magnetic susceptibility of the specimen. Theoretical calculations agree with experiments reasonably.
