鄂尔多斯盆地盐下天然气勘探取得重大突破,在马四段多次钻获高含硫化氢天然气,地质和地球化学特征表明其成因和来源尚不明确。通过系统采集马四段天然气、乌拉力克组页岩气和上古生界致密砂岩气样品,测定天然气的组分和碳、氢同位素组成,结合盆地中东部地质实际开展天然气成因和气源研究。结果显示,马四段天然气是以甲烷为主的干气,干燥系数平均值为0.97,乙烷平均含量为1.07%,丙烷平均含量为0.32%,其余重烃气平均含量0.38%;硫化氢平均浓度为124774×10-6,是TSR作用的产物,明显区别于上古生界致密砂岩气和乌拉力克组页岩气,研究区内由西向东硫化氢含量逐渐降低;马四段天然气中甲烷碳同位素组成介于-44.8‰~-36.4‰,平均值为-40.3‰;乙烷碳同位素组成介于-27.7‰~-19.1‰,平均值为-24.3‰;甲烷氢同位素组成介于-172‰~-140‰,平均值为-162‰;乙烷氢同位素组成介于-140‰~-112‰,平均值为-119‰;马四段天然气具有较轻的甲烷碳同位素组成和较重的甲烷氢同位素组成,指示马四段天然气具有与上古生界煤成气不同的气源。以甲烷碳、氢同位素组成及组分作为高含硫天然气的主要判识参数,识别出马四段天然气具有“自生自储”的特征,气源岩为马家沟组含膏层系发育的海相烃源岩;TSR促进了烃类向非烃的转化,重烃气向甲烷的转化,也会导致烃类碳同位素组成的变化;部分气藏乙烷碳同位素组成已经明显重于干酪根碳同位素组成,超出了热演化的影响范围,凸显TSR作用对乙烷碳同位素影响较大。基于马家沟组盐下天然气的形成演化地质背景,初步估算TSR能导致乙烷碳同位素组成变重5‰~10‰。

Nitric oxide was discovered in both the lab and the alga culture pond of Daya Bay (1―300 m3) before the growth of alga reached the maximum. The results included: (1) NO was detected before the growth of alga reached the maximum in the case of red tide alga and food alga, and the concentration of NO decreased rapidly after the growth maximum; (2) the curve between NO con-centration and time indicated that the concentration of NO in the daytime was more than that at night, and the maximal concentration of NO appeared in the midday (1―3 pm); (3) the growth of alga reached the maximum in the alga culture pond of Daya Bay in about 8―10 d, and NO was discovered in 5―7 d; (4) the measured NO concentration was 10-9 mol/L, 10-9―10-8 mol/L, and 10-8 mol/L for Haeterosigma akashiwo, mixed alga in Daya Bay and Chaetoceros Curvisetus individually; (5) the relation of illumination with NO production was discussed.

Numerous privacy-preserving issues have emerged along with the fast development of Internet, both in theory and in real-life applications. To settle the privacy-preserving problems, secure multi-party computation is essential and critical. In this paper, we have solved two problems regarding to how to determine the position relation between points and curves without revealing any private information. Two protocols have been proposed in order to solve the problems in different conditions. In addition, some building blocks have been developed, such as scalar product protocol, so that we can take advantage of them to settle the privacy-preserving computational geometry problems which are a kind of special secure multi-party computation problems. Moreover, oblivious transfer and power series expansion serve as significant parts in our protocols. Analyses and proofs have also been given to argue our conclusion.

ADAM (2-((2-((dimethylamino)methyl)phenyl)thio)-5-iodophenylamine) is suggested as a promising serotonin transporter (SERT) imaging agent for central nervous system. In this paper, biodistribution studies in rats showed that the initial uptake of 131I-ADAM in the brain was high (1.087%ID at 2 min post-injection), and consistently displayed the highest binding (between 60~240 min post-injection) in hypothalamus, a region known with the highest density of SERT. The specific binding((T/CB)-1) of 131I-ADAM in hypothalamus were 2.94, 3.03 and 3.09 at 60, 120 and 240 min post-injection, respectively. The (T/CB)-1 was significantly blocked by pretreatment with paroxetine, which is known as a serotonin site reuptake inhibitor, while another nonselective competing drug (5HT2A antagonist) Ketanserin, showed no block effect. The rat brain autoradiography and analysis showed that there was a high 131I-ADAM uptake in hypothalamus, the ratio of hypothalamus/cerebellum was significantly reduced from 7.94±0.39 to 1.30±0.56 by pretreatment with paroxetine at 60 min post-injection. Blood clearance kinetics was performed in rats, and the initial half-life of 13.79 min and late half-life of 357.14 min were obtained. The kinetic equation is: C=3.6147e-0.0725t + 1.0413e-0.0028t. The thyroid uptake was 0.009% ID and 1.421% ID at 2 min and 120 min post-injection, respectively, suggesting that in vivo deiodination may be the major route of metabolism. Toxicity trial showed that the dose per kilogram administered to mice was 1000 times greater than that to humans, assuming a weight of 50kg. These data suggest that 131I-ADAM may be useful for SPECT imaging of SERT binding sites in the brain.

对22种有机磷农药(OPPs)在污水处理厂厌氧/缺氧/好氧与MBR的组合工艺(A2/OMBR)中的去除特征进行了长期研究。分析结果显示22种有机磷农药经工艺处理后出水中平均浓度由0.98ng/L (乐果)到20.56ng/L (甲基内吸磷)不等。去除率除对硫磷79.6%和甲基内吸磷79.0%外，其余均达到84.5%以上。进一步分析其不同处理阶段的泥水分配系数(Kd)，厌氧和MBR单元均大于3500L/kg-MLSS，缺氧和好氧单元均大于2500L/kg-MLSS，表明污泥对部分有机磷农药具有较好的吸附性能，这些有机磷农药的去除主要是通过污泥吸附和生物降解两种方式共同完成。
