浙江深水灯光围网产量的时空分布

根据浙江省海洋水产研究所的监测资料和浙江省沿海各县、市的渔业统计资料,对2008年度浙江深水灯光围网产量的时空分布进行了研究与分析.结果表明:2008年浙江深水灯光围网的产量主要分布于27°～29° N、123°～127°E之间海域;作业渔场主要为浙南渔场与浙北外海渔场,其中又以浙南渔场为主;渔期主要为夏、秋、冬三季,其中秋季占全年总渔获量的近50%;各季各渔场的产量重心有所变动,其中,浙北外海渔场与浙南渔场的产量重心在纬度方向上呈逐季向北推移的趋势.建议对浙江深水灯光围网的船组数量进行适当控制,并对2009年开始施行的东海区围网休渔期进行适当调整,以促进浙江省围网渔业的可持续发展及鲐鲹鱼资源的可持续利用.

关于东海区灯光围网管理的研究

对1998～2005年东海区灯光围网的主捕品种、数量分布及其捕捞规模进行调研,研究认为灯光围网的主捕品种为日本鲐、澳洲鲐、竹筴鱼和蓝圆鲹等,且尚有一定的资源量。东海区的灯光围网近年来规模发展迅速,对上述鲐鲹鱼有良好的诱捕效果。从可持续利用资源角度出发,对其应实施规范管理,其措施为:(1)确定大型机轮围网、机帆船灯光围网的规模数量、渔船吨位、马力、网具规格等;(2)实行捕捞许可证制度;(3)成立全国灯光围网协会,配合农业部渔业局对灯光围网制订有关措施,进行专项管理。     

浙江机轮围网渔获量分布的研究

根据浙江省海洋水产研究所的监测资料,对2003～2006年浙江机轮围网渔获量的时空分布进行了研究与分析,结果表明:近年来,东海海域是浙江机轮围网的主要作业渔场,其渔获量重心呈逐年向外移动的趋势,外移的原因除与复杂的渔场环境因素相关外,还与近年来浙江群众传统灯光围网与2006年深水灯光围网的迅猛发展有关;中心渔场为高渔获量与高CPUE区,主要分布于33°～35°N、124°～125°E,26°～28°N、123°～125°E海域。     

浙江海域鲐鳆鱼资源量评估

根据2009—2010年浙江海域灯光围网捕获的鲐鳄鱼随机取样获得的数据,使用叉长结构实际种群分析法（LVPA）对鲐鲣鱼资源状况进行了评估。结果显示,采集鲐鱼样品的叉长分布在55。396mm之间,极限叉长L。=406mm,生长参数K：0．34。捕捞死亡系数（F）为0．82,峰值出现在叉长为285mm处,等于1．29。补充高峰出现在6—8月。蓝圆够样品的叉长分布在34～268mm之间,极限叉长Lm=289mm,生长参数K=0．43。捕捞死亡系数（F）为0．35,峰值出现在叉长为135mm处,等于0．47。补充高峰出现在4—8月。单位补充量产量分析显示,当前开发状况距最适渔业状态较远,首次捕捞叉长不足极限叉长的20％,需要增大网目尺寸,以保护鲐够鱼资源。结合2009—2010年浙江海域鲐骖鱼渔获物资料和灯光围网船组资料,估算了浙江海域鲐够鱼这2年的现存资源量。结果表明,2009—2010年浙江海域鲐够鱼现存资源量为60．4×10^4t左右,最适可捕量为41．0×10^4t。浙江海域鲐骖鱼补充率最高月份为8月份,其值达15．52％。

Markedness and its Interpretation in Language Use

Language markedness is a common phenomenon in languages, and is reflected from hearing, vision and sense, i.e. the variation in the three aspects such as phonology, morphology and semantics. This paper focuses on the interpretation of markedness in language use following the three perspectives, i.e. pragmatic interpretation, psychological interpretation and cognitive interpretation, with an aim to define the function of markedness.     

Features of Women's language

Language is a means of verbal communication. People use language to communicate with each other. In the society, no two speakers are exactly alike in the way of speaking. Some differences are due to age, gender, statue and personality. Above all, gender is one of the obvious reasons. The writer of this paper tries to describe the features of women＇s language from these perspectives： pronunciation, intonation, diction, subjects, grammar and discourse. From the discussion of the features of women＇s language, more attention should be paid to language use in social context. What＇s more, the linguistic phenomena in a speaking community can be understood more thoroughly.     

Characterization of Ordovician carbonate reservoirs, southeastern Saskatchewan, Canada

The discovery of the prolific Ordovician Red River reservoirs in 1995 in southeastern Saskatchewan was the catalyst for extensive exploration activity which resulted in the discovery of more than 15 new Red River pools. The best yields of Red River production to date have been from dolomite reservoirs. Understanding the processes of dolomitization is, therefore, crucial for the prediction of the connectivity, spatial distribution and heterogeneity of dolomite reservoirs.The Red River reservoirs in the Midale area consist of 3～4 thin dolomitized zones, with a total thickness of about 20 m, which occur at the top of the Yeoman Formation. Two types of replacement dolomite were recognized in the Red River reservoir: dolomitized burrow infills and dolomitized host matrix. The spatial distribution of dolomite suggests that burrowing organisms played an important role in facilitating the fluid flow in the backfilled sediments. This resulted in penecontemporaneous dolomitization of burrow infills by normal seawater. The dolomite in the host matrix is interpreted as having occurred at shallow burial by evaporitic seawater during precipitation of Lake Almar anhydrite that immediately overlies the Yeoman Formation. However, the low δ18O values of dolomited burrow infills (-5.9‰～ -7.8‰, PDB) and matrix dolomites (-6.6‰～ -8.1‰, avg. -7.4‰ PDB) compared to the estimated values for the late Ordovician marine dolomite could be attributed to modification and alteration of dolomite at higher temperatures during deeper burial, which could also be responsible for its 87Sr/86Sr ratios (0.7084～0.7088) that are higher than suggested for the late Ordovician seawaters (0.7078～0.7080). The trace amounts of saddle dolomite cement in the Red River carbonates are probably related to "cannibalization" of earlier replacement dolomite during the chemical compaction.     

低渗透非均质砂岩油藏启动压力梯度研究

理论推导与室内实验相结合,建立了低渗透非均质砂岩油藏启动压力梯度确定方法。首先借助油藏流场与电场相似的原理,推导了非均质砂岩油藏启动压力梯度计算公式。其次基于稳定流实验方法,建立了非均质砂岩油藏启动压力梯度测试方法。结果表明:低渗透非均质砂岩油藏的启动压力梯度确定遵循两个等效原则。平面非均质油藏的启动压力梯度等于各级渗透率段的启动压力梯度关于长度的加权平均;纵向非均质油藏的启动压力梯度等于各渗透率层的启动压力梯度关于渗透率与渗流面积乘积的加权平均。研究成果可用于有效指导低渗透非均质砂岩油藏的合理井距确定,促进该类油藏的高效开发。     

On Tragic Consciousness In The Works By Ernest Hemingway

As an American modern novelist who were famous in the literary world, Hemingway was not a person who always followed the trend but a sharp observer. At the same time, he was a tragedy maestro, he paid great attention on existence, fate and end-result. The dramatis personae's tragedy of his works was an extreme limit by all means tragedy on the meaning of fearless challenge that failed. The beauty of tragedy was not produced on the destruction of life, but now this kind of value was in the impact activity. They performed for the reader about the tragedy on challenging for the limit and the death.

An Index mechanism for multi-scale view in spatial databases

There are numerous geometric objects stored in the spatial databases. An importance function in a spatial database is that users can browse the geometric objects as a map efficiently. Thus the spatial database should display the geometric objects users concern about swiftly onto the display window. This process includes two operations:retrieve data from database and then draw them onto screen. Accordingly, to improve the efficiency, we should try to reduce time of both retrieving object and displaying them. The former can be achieved with the aid of spatial index such as R-tree, the latter require to simplify the objects. Simplification means that objects are shown with sufficient but not with unnecessary detail which depend on the scale of browse. So the major problem is how to retrieve data at different detail level efficiently. This paper introduces the implementation of a multi-scale index in the spatial database SISP (Spatial Information Shared Platform) which is generalized from R-tree. The difference between the generalization and the R-tree lies on two facets: One is that every node and geometric object in the generalization is assigned with a importance value which denote the importance of them, and every vertex in the objects are assigned with a importance value,too. The importance value can be use to decide which data should be retrieve from disk in a query. The other difference is that geometric objects in the generalization are divided into one or more sub-blocks, and vertexes are total ordered by their importance value. With the help of the generalized R-tree, one can easily retrieve data at different detail levels.Some experiments are performed on real-life data to evaluate the performance of solutions that separately use normal spatial index and multi-scale spatial index. The results show that the solution using multi-scale index in SISP is satisfying.     

Jane Eyre——A Feminist In The 19th Century

In the 19th century the society was controlled by men, and women were just appendants of them, they had not any rights and freedom. But Jane was an exception, she showed some characteristics of early feminist. Jane showed her characteristics of feminism in three aspects: rebellion, equality, and independence. These characteristics were helpful to her success, and feminism is the only way out for women of that time.

Exchange-Correlation and Electronic Excitation Energies from Pairing Matrix Fluctuations

We have developed an adiabatic connection to formulate the ground-state exchange-correlation energy in terms of pairing matrix linear fluctuations.This formulation of the exchange-correlation energy opens a new channel for density functional approximations based on the many-body perturbation theory.We illustrate the potential of such approaches with an approximation based on the particle-particle Random Phase Approximation(pp-RPA).This re-
