From the angle of engineering application, this article analysed the corrosion characteristics and damage causes of the current structural used concrete in the region of Hangzhou gulf, on the basis of on-site survey of all the Marine concrete projects in that area. Taking HPC used in Marine as research objective, this article put great emphasis on the influence of the composition cementing material system to concrete performance, and make a preliminary probe into the action mechanism of the composite effects of various mineral materials in improving the performance of concrete by laser measuring size machine and EMPA. Through experiments, the article discussed how chloride ingression in concrete will be effected by such factors as exposure time, chloride binding, environment temperature, stress and cracks conditions; and also analysed the symptoms of these factors in the model of concrete service life prediction by conference to all related research reports both home and aboard. On the foundation of abovementioned research, this paper brought up an engineering model of service life prediction of marine concrete, which is based on chloride-induced corrosion.

The owner of an incomplete statistics in the Australian assets of Chinese companies to list, China National Petroleum Corporation, Sinopec and CNOOC three domestic oilman's name emerged as a major surprise: May 15, 2003, CNOOC to spend 348 million U.S. dollars acquisition Australian North West Shelf LNG project upstream products and reserves the rights and interests; September 9, 2007, China Petroleum Group to Australia's biggest oil and gas producer Woodside Petroleum to purchase up to 45 billion Australian dollars worth of liquefied natural gas; June 19 this year Japan, China's petrochemical enterprises to 561 million U.S. dollars to the Australian oil producers to buy oil fields in the Timor Sea Puffin rights and interests of 60 percent.

在我国企业在澳大利亚的资产的不完全统计，业主名单，中国石油天然气集团公司，中石化和中海油三大国内石油商的名字成为一个主要的惊喜：2003年5月15日，中海油花费三点四八〇亿美元收购澳大利亚西北大陆架LNG项目的上游产品及储量的权利和利益； 2007年9月9日，中国石油集团向澳大利亚最大的石油和天然气生产商伍德赛德石油公司购买最多45亿美元的液化天然气澳元；今年6月19日，日本，中国的石化企业五万六千一百点零零万美元向澳大利亚石油生产商收购帝汶海海鹦的权利和利益的百分之六十油田。

海鲢任一种海鱼，尤指海鲢海鲢，它是热带海洋中的一种

The unique geographic position of shelf and marginal sea causes the material supply of seafloor sediments plenteous and the material sources of them diverse. As terrigenous materials being input into the sea continually and a great deal of authigenous minerals coming into being, the sediments can be used to study the change of sea level and the meterail and energy exchange between the sea and the land.

陆架和边缘海独特的地理位置决定了海底沉积物物源的充足与多样性，陆源物质源源不断地通过河流输入到海洋中，同时大量的自生矿物在海洋中生成，因此研究陆架和边缘海海底沉积物，可以为研究海平面变化、海陆之间物质和能量的交换等作用提供信息。

D2 hydantoinase (EC3151212) can change the D type racemates of the racemic D,L252 monosubstituted hydantoin to D2N2 carbamoylase, and the leftover L252 monosubstituted hydantoin due to never reacted with D2 hydantoinase, shown as figure 1, firstly racemizing, thus makes the D,L2 hydantoin completely changes to pure optical D2N2 carbamoylase, and then be changed to D2 amino acid.

海因酶具有底物特异性，D2海因酶(EC 3151212)可转化外消旋的D ，L252单取代海因中的D型消旋体成为D2N2氨甲酰氨基酸，剩余的L252单取代海因由于完全不被 D2海因酶所作用，如图 1所示，先进行消旋，从而使得 D ，L2海因完全转化为光学纯的 D2N2氨甲酰氨基酸，并进一步被转化为D2氨基酸。

By polarization curve and EIS, equivalent circuit in initial corrosion stage was brought forward. With which the oxygen diffusion (oxygen as a depolarizing agent in cathode) mechanism was proposed and discussed.

作者认为API X60管线钢在不同类型海泥中腐蚀速度的差别主要是由于作为阴极去极化剂的氧在不同类型海泥中的扩散速度不同；根据API X60管线钢在不同类型海泥中的电化学阻抗频谱特征，作者提出了腐蚀过程的等效电路，对腐蚀机制进行了解释。

Because ventilating requirement of cross-ocean tunnel, expecially long distancecross-ocean tunnel, ventilating shaft should be set at sea.
