Mo isotopic signatures in sediments can be used as an indicator for redox conditions of paleo-environment and corresponding paleo-oceanography. Therefore, molybdenum isotopes can be used as a powerful tool for understanding the redox conditions of local or regional depositional environment, the biogeochemical cycle of sulfur or carbon, and the geochemical evolution of ancient oceans.
沉积物中的Mo同位素既能指示古沉积环境的氧化还原条件,也能够指示与之相关的古海洋地理环境,因此,Mo同位素是了解局域至区域沉积环境的氧化还原条件、硫和碳地球化学循环及古海洋化学演化等的强有力工具。

The research achievement are acquired as follows: 1From mathematical models for inverse scattering in two dimensional homogenous media including Dirichlet, Neumann, Robin,all kinds of probable mixed boundaries and cracks, direct and inverse scattering are discussed, and ill-posed integral equation and indicator function method are formulated for the diverse of boundary identification. It is shown that the kernel of the integral equation characters the boundary of scatterer, which is determined by solving it by virtual of regularity method, meanwhile, some numerical tests are given.
本研究取得了如下研究成果: 1)在二维均匀介质逆散射各种边界识别的数学模型(包括Dirichlet,Neumann,Robin,各种可能的混合边界问题,裂纹问题)下,分别考虑了正散射问题和逆散射问题,推导了上述各种边界识别的不适定积分方程以及指示函数方法,由于积分方程的核充分表征了散射物的边界,由此说明只要利用正则化方法求解该积分方程,就可以确定散射物的边界,并给出了一些数值实验。

Distribution of biogenic silica content in surface sediments from deep water areas showed that it could not only reflect the paleoproductivity of siliceous micropaleontology in surface waters, but also indicate the strong or feeble upwelling. Thus, it was further confirmed that using biogenic silica content in sediments to trace upwelling and its change was effective and reliable. The analyzed result showed that radiolaria and poriferous specula have more contribution for biogenic opal, comparing with diatom in surface sediments from the northern studied area, probably owing to the diatom dissolved easily away and eaten by other organisms with little effort.
深水区表层沉积物中生物硅的含量分布表明,其不仅能反映出表层水体中硅质生物的古生产力水平,而且还能指示上升流的强弱,从而进一步证实了利用沉积物中生物硅含量来追踪上升流发育和变化的有效性与可信度研究结果还显示,在研究区域中北部表层沉积生物硅中放射虫和海绵骨针较硅藻占有更大的比重,这可能是由于硅藻易被溶解并易被其他生物体摄食的缘故。

Among them strain MZ1 had been confirmed a lysogenic strain by indicator strain ZK1 after producing phage plaques induced by Mitomycin C.Two templates of overnight cultivation and its DNA from strain MZ1 were then amplified in the same time with five pairs of primers designed from the same phage,and the same products were obtained,suggesting that strain MZ1 was also confirmed a lysogenic strain by PCR method.
MZ1菌株的过夜培养液与指示菌ZK1(血清型H25)混匀并在双层琼脂上培养12 h后出现了滴度为2×107 pfu的噬菌斑,从而证明生产菌株MZ1确为溶原菌;又以GIL01同源性较高的其它四个基因设计引物,分别以MZ1的培养物及其溶原性噬菌体基因组为模板进行PCR扩增,结果两者得到几乎一致的带型,进一步证明了生产菌株MZ1为溶原菌,说明利用PCR法检测鉴定苏云金杆菌的溶原性是可行的。

Geochemical characteristics of 36 Tertiary mudstone samples from Kuqa depression show that the content of CaO is very high, which can somewhat dilute other major elements, trace elements and rare elements. Some reliable indicators for provenance analysis show the source rock nature of noncarbonate sediments. The REE distribution pattern is similar to that of the upper continental crust, characterized by enrichment of LREE and negative Eu anomalies. Some trace element ratios show that the source rocks are mainly felsic.
