Methods Male SD rats underwent WIR stress for 2,4 and 8 hours. Ulcer index of stomach was chedsed by Guth method, nitrite production was measured by Greiss assay, nitric oxide synthase activities and L-arginine transport rate were determined by isotope tracer method.

大鼠浸水－束缚应激2、4和8 h，以胃溃疡指数作为应激损伤的标识，采用Greiss法测定血小板孵育液中亚硝酸盐NO2(上标-含量；同位素法测其一氧化氮合酶活性和L-精氨酸转运量。

The extent of intracolonial integration in massive hermatypic corals was investigated by carbon and nitrogen stable isotope analysis. The δ13C of coral tissues were higher than zooxanthellae.

Signal intensity and system blank of five argon isotopes obtained indicate that the system blank level adopted by the authors is low enough to get a reasonable isochron age for single mineral grains frown Mesozoic or older samples.

获得的5个氩同位素空白本底水平表明，本系统已经完全具备对中生代或更老的地质样品进行单颗粒全熔法等时线定年的能力。

Eclogites north of the fault give similar Sm–Nd isochron ages (131–126 Ma) but otherwise differ in that they are strongly overprinted by a lower pressure assemblage and, along with associated HP/LT rocks, give much younger 40Ar/39Ar ages of 88–55 Ma indicating a later amphibolite facies metamorphic event.

榴辉岩断层以北的始可予以实现位置相似的Sm - Nd同位素年龄（131-126 Ma）的方式不同，但他们强烈较低的压力叠加和组合，以及相关的惠普/审裁处的岩石，让更年轻的40Ar/39Ar年龄在88-55马说明后来角闪岩相变质事件。

In order to determine the metallogenic epoch of the gold- silver deposit s in Zhejiang province, the fluid inclusions in quartz from the Huangshan gold deposit, Zhilingtou gold- silver deposit aad Haoshi silver deposit were dated by the Rb-Sr isochron method.
