恒星的初始-终止质量关系

本文研究了星族ＩＲＧＢ／ＡＧＢ星外壳结合能为零时的核质量与其初始质量的关系，发现此关系与Ｗｅｉｄｅｍａｎｎ和Ｋｏｅｓｔｅｒ观测得到的初始终止质量关系相符，并与Ｚｈａｎｇ和Ｋｗｏｋ得到的行星状星云核质量分布的观测结果相符合．采用相同的假设，本文还得到了星族ＩＩ恒星的初始终止质量关系．对于相同的初始质量，星族Ｉ恒星的终止质量比星族Ｉ的大～１０％－２０％．     

土壤中氟的形态分析

以宁夏盐池地区高氟土壤为例,采用连续提取法对土壤样品中各形态氟进行提取,离子色谱法测定各形态氟的含量。根据研究目的及土壤特点将氟的形态划分为水溶态、离子交换态、可还原态、可氧化态及残渣态5种形态;对各种形态连续提取过程中使用的提取液进行了选择。采用建立的方法获得提取土壤中F-的检出限为0.76μg/g;方法精密度(RSD,n=7)各形态氟为水溶态氟11.3%,离子交换态氟13.5%,可还原态氟10.7%,可氧化态氟8.9%。     

Shear strength characterization of municipal solid waste at the Suzhou landfill, China

The current practice of slope stability analysis for a municipal solid waste (MSW) landfill usually overlooks the dependence of waste properties on the fill age or embedment depth. Changes in shear strength of MSW as a function of fill age were investigated by performing field and laboratory studies on the Suzhou landfill in China. The field study included sampling from five boreholes advanced to the bottom of the landfill, cone penetration tests and monitoring of pore fluid pressures. Twenty-six borehole samples representative of different fill ages (0 to 13 years) were used to perform drained triaxial compression tests. The field and laboratory study showed that the waste body in the landfill can be sub-divided into several strata corresponding to different ranges of fill age. Each of the waste strata has individual composition and shear strength characteristics. The triaxial test results showed that the MSW samples exhibited a strain-hardening and contractive behavior. As the fill age of the waste increased from 1.7 years to 11 years, the cohesion mobilized at a strain level of 10% was found to decrease from 23.3 kPa to 0 kPa, and the mobilized friction angle at the same strain level increasing from 9.9° to 26°. For a confinement stress level greater than 50 kPa, the shear strength of the recently-placed MSW seemed to be lower than that of the older MSW. This behavior was consistent with the cone penetration test results. The field measurement of pore pressures revealed a perched leachate mound above an intermediate cover of soils and a substantial leachate mound near the bottom of the landfill. The measurements of shear strength properties and pore pressures were utilized to assess the slope stability of the Suzhou landfill.     

低风速下海面附近气温场对海气动量通量的影响

实用测的海上和层平均风剖面数据和温度剖面数据，通过数据回归和迭代方法计算出了在不同大气稳定情况下的海面阻力系数。得到了与前人理论计算一致的结论：海面阻力系数随海面大气稳定度的增加而减小，另外，我们还发现：在海面风速小于１３ｍ／ｓ时，不能认为气温剖面外推到海面的值与海面水温的是一致的。这样若用海气温差作为衡量海面上方大气的稳定程度，难于得到上面给出了理结论。这一点同前人的理论计算结果是不相同的。

栉孔扇贝(Chlamys farreri) 血细胞类型及抗菌力的研究

用2种方法将栉孔扇贝血细胞分为2大类透明细胞、颗粒细胞.吉姆萨染色观察,透明细胞的细胞质中颗粒很少,细胞核圆形,居中,细胞质较少,核质比大;颗粒细胞比透明细胞大且多,染色深,但核质比小,在细胞质中有颗粒,有些颗粒细胞具双核.密度梯度离心结果,透明细胞主要位于上层,颗粒细胞则大部分位于下层.吞噬力、抗菌活力、溶菌活力及活性氧检测结果表明,颗粒细胞均强于透明细胞.

南海輓近海平面变化与构造升降初步研究

揭示南海輓近海平面变动和古岸线诸多遗迹,探讨晚更新世以来海平面变化一般规律,初步分析南海周缘中全新世和现代地壳构造升降速率,得出本区海平面上升率适中参考值为0.10—2.0mm/a,初步估算未来50年内海平面变化趋势在1.26—4.0mm/a之间;而构造升降受块断差异运动控制,一般规律是南海北部沿岸自东向西递减,由福建南部1.15mm/a至海南岛南部0.54mm/a。近代地壳形变资料亦证实这种变化规律。
