Low cycle fatigue tests and crack growth propagations tests on P91 pipe base metal and its weld joints were conducted at three different temperatures: room temperature, 550℃ and 575℃. The strain-life was analyzed, and the changes in fatigue life behavior and fatigue growth rates with increasing temperature were discussed. The different properties of the base metal and its weld joint have been analyzed.

Z-parameter method based on the Larson-Miller relationship is proposed to assess remaining life of a 1Cr5Mo steel. The non-linear master curve of stress a vs. Larson-Miller parameter P of the steel can be expressed as: P=29.608-5. 085logσ. A family of curves parallel to the master curve can be expressed as: P=29.608-Z-5.085logσ, where the value of Z represents the magnitude deviated from the master curve. A relationship between the value of Z-parameter and the level of spheroidization E (mi-crostructural degradation) can be expressed as: Z=0.203(E-1).

Systematic mass spectrometric 230Th ages are reported for a Ponies coral reef terrace from Dengloujiao, Leizhou Peninsula, South China Sea. Seven episodes of coral growth were recognized in this terrace: 7125±96, 6764±29, 5826±37, 5006±54, 2543±24, 1915±15, and 1513±22 calendar years before present (cal. aBP). 50% of the coral age popula-tion fall between 7200 and 6600 cal. aBP, marking post-glacial stabilization of global sea level. Considering the facts that (i) Dengloujiao reef flat was measured at 1.6-2.5 m above modern tidal datum plane; (ii) modern Parties corals in the South China Sea are living at least ~1 m below the modern tidal datum plane; (iii) the top 20-30 cm of the reef was eroded; and (iv) crustal subsidence in the region since mid-Holocene was negligible, we conclude that the above age groups record at least two major periods (7200-5000 and 2500-1500 cal. aBP) of high sea-level at least 2.9-3.8 m above the present-day level.

质粒是环状双键 DNA 分子,可在寄主细胞中自我复制。细菌质粒对细菌本身的抗药性,降解有机物和毒素的能力,细菌的附着力、细胞渗透性和细菌的转换系统的功能都有重要作用。1988年,Aski 已检定出革兰氏阳性与阴性细菌体内都含有抗药性质粒。Crosa 等(1977)发现弧菌(Vibrio angwill-arum)体内的毒性质粒与转铁系统有关。
