Granulite in eastern Shandong is mainly exposed in Laixi. Pingdu, Changyi and Anqiu, and the diagnosticmineral assemblage is Opx+Cpx+Hb+PI±Q±Sca. The appearance of orthopyroxene and Its coexistence withhornblende indicate that the reaction Hb+Q=Opx+Cpx+PI+H2O did not proceed completely and thereforethese rocks belong to the amphibolite-granulite transition facies. i.e., belonging to hornblende-granulitesubfacics. According to the data obtained from such geothermometers and geobarometers as Opx-Cpx,Opx-Hb. Cpx-Hb, Hb-PI. Sca-PI and Fe-Ti oxides, it has been determined that the temperature of the mainmetamorphic stage was 720-810℃, the pressure 0.5 GPa and fo210-15.5, showing a geothermal gradient of41-46℃/km, and thus the rocks belong to "low-temperature" and low-pressure granulite facies.

Manganese nodules in areas CP and CC of the central Pacific are rich in REE. Comparatively speaking,the REE contents of nodules in area CP are hihger than those in area CC; and the REE contents of nodulesfrom seamounts are higher than those of nodules from sea-floor plains and hills. Within the nodules, the REEshow a zonal distribution. The REE distribution patterns of the nodules are similar to those of the sedimentsand have a mirror image relationship with those of the sea water. Trivalent REE were not obviously differenti-ated when they entered into the nodules from the sea water.A major factor causing the difference of REE abundances between nodules and sediments is the redoxconditions. The redox intensity of the ocean floor of the Pacific is controlled mainly by Antarctic Bottom Wat-er(AABW), The iron-bearing facies in the nodules is the main carrier of REE.

Summer monsoons （South Asian monsoon, South China Sea monsoon and Subtropical monsoon） are prominent features of summertime climate over southern China. Dif- ferent monsoons carry different inflow moisture into China and control the temporal and spatial distributions of precipitation. Analyses of meteorological data, particularly wind, tempera- ture and pressure anomalies are traditional methods of characterizing moisture sources and transport patterns. Here, we try to utilize the evidence from stable isotopes signatures to trace summer monsoons over southern China. Based on seven CHNIP （Chinese Network of Iso- topes in Precipitation） observatory stations located in southern China, monthly composite precipitation samples have been collected and analyzed for the composition of δ^18O during July, 2005. The results indicated that the spatial distributions of δ^18O in precipitation could properly portray the moisture sources together with their transport pathways. Moreover, the amount effect, altitude effect, temperature effect and the correlation between δ^18O vs. relative humidity were discussed.

通过建立1998～2008年SITC Rev．3五位编码产品与制造业22个行业的对应关系，构建行业出口技术水平测算指标。并采用系统动态∞心压方法实证研究了中国制造业出口技术结构的影响因素。结果表明，内部知识变量在出口结构深化与升级中的作用得到强化；外资企业在中国研发投入与创新意愿不足；FDI对出口技术结构升级的影响存在行业异质性；劳动密集型行业的资本深化对中国出口技术水平具有稳健的提升作用。可见内部动力挖潜和影响因素的行业异质性，决定了不同行业应强化有利于本行业出口技术水平提升的因素，在采取手段提高本行业出口技术水平时，应同时兼顾国家外资与就业政策目标。
