Consequently, the enzymatic hydrolyzable P may contribute to the internal loading of the eutrophic lake, and stratification of kinetics and compositions of phosphatase in shallow lake is theoretically noticeable.

因此，富营养湖泊沉积物中磷的&内负荷&应有可酶解有机磷的含义，浅水湖泊中磷酸酶的活性组成和动力学参数的分层现象当为湖沼学研究中值得深入探讨的新理论问题。

Results Microstructure of callus showed that the area of mature trabecular in callus of OPFM group was smaller than that of CFM group, and was thinner with a wide intertrabecular distance. The dynamic parameters demonstrated that the fluorescent labeling percentage on the trabecular surface of OPFM group was lower than that of CFM group, but bone mineral apposition rate was higher.

结果 ①骨痂组织骨组织形态计量学结果发现：OPFM组成熟小梁骨占骨痂面积比CFM组小，且小梁骨厚度变薄、小梁骨间距较宽；同时骨小梁动力学参数显示：OPFM组骨小梁表面荧光标记百分比较CFM组低，而骨矿化沉积率却较高。

According the demand of the national"908"special project, the distribution of the detrital minerals and the characteristics of genetic mineralogy of the surficial sea-floor sediments offshore Hainan islands(CJ19 subzone) were studied by means of lens stereoscope, micropolariscope, SEM, EMPA and LA-ICPMS.

依托国家&908&专项项目，借助立体及偏光光学显微镜、扫描电镜、电子探针微分析和激光剥蚀等离子质谱等先进技术手段和方法，对环海南岛海域(CJ19区块)海底表层沉积物中碎屑矿物的分布和锆石、石榴石的成因矿物学进行了研究。

We report cases of PJS in three men who were 31, 20 and 17 years old. They had typical clinical presentations of mucocutaneous pigmentation and intestinal obstruction, and image findings of intussusception.

我们收集了三个Peutz-Jeghers Syndrome的病例，都有典型的临床上皮肤黏膜色素沉积，急性肠阻塞，及影像学上肠套叠的表现。

Contour current is one of the important sedimentary dynamics, the deposits (so-called contourite) of which contain important information of palaeooceanography and palaeoclimatology.

等深流是大洋环境非常重要的动力学机制，其沉积蕴含了重要的古海洋学和古气候信息，对其进行解析是近些年国际海洋学、气候学的研究热点。

Based on sequence stratigraphy theory and method,and the comprehensive analysis of cores,seismic and logging data,the depo-sitional filling styles of Palaeogene rifting period in Yuanyanggou area of west Liaohe Depression were divided into 4 second-order sequences and 8 third-order sequence s.
