作者从二度磁性体的磁异常公式出发,推导出各异常的不定积分变换结果,并由变换结果绘制不定积分变换的磁异常参量图.本文选取2种规则形态磁性体,在取不同空间几何参数的条件下,讨论它们不定积分变换后参量图的曲线变化规律,并总结其异常特征,而后将其与积分变换前的参量图对比进行磁异常讨论和效果分析.该方法能反映一些重要的地质信息,将有助于实际的磁异常解释.     

细基江蓠繁枝变种在浙江越冬的研究

应用从湛江引入,并在浙江自然越冬后生长正常的,以及从海口新引入的细基江蓠繁枝变种,作为实验材料进行越冬保种研究。本文首次报道了不同的种藻密度、培养液比重、水层、光强、底质及人为低温处理,对存活和生长的影响。结果表明:新引入的种藻具生长快、对环境的剧烈变化敏感;已越冬的种藻更能适应低温低比重的条件。以0.3m左右的水层,比重1.010,避免直射强光的低光照,能够安全保种越冬。低温干冻比水冻更易致死。可以经受7天的0℃低温。砂质的底质有利于越冬保种。在浙江普通的育苗室内就可以进行越冬,越冬后,死亡率低于0.07％/d。     

南海异沙珊瑚属一新种

异沙珊瑚(Heteropsammia)是仅分布于印度西太平洋热带和亚热带浅海区的一个属，隶石珊瑚目，因与星虫共栖而著名，过去共报道过8种，但在本世纪七十多年中，未增添过一个新种。经Horst(1922 、1926) 、Yabe and Eguchi(1932、1942)等人的分类研究和归并后，迄今一般认为，该属只有4种，即：单体珊瑚两种——H.cochlea (Spengler)和H.ovalis Semper，单体兼群体珊瑚一种——H. michelinii Milne-Edwards and Haime，群体珊瑚一种——H.geminata VetriIl。 我们在整理1958-1960年中国近海海洋调查所采集的与星虫共栖的石珊瑚标本时，发现在海南岛西南近岸水域拖网采到的一个异沙珊瑚标本，其形态特征与该属己记载的种都不相同，经详细研究后，确定是一个新种。     

台湾省恒春西南海域声速场分析

选取联系南海与台湾海峡 及巴士海峡的主要海上交通和军事要道－我国台湾省恒春西南海域作为研究海域,依据1998年夏,冬季对本海域海洋环境补充调查的CTD资料,按《海洋调查资料处理》的声速换算经验公式,推算得到本海域的海水声速系列,结合该海域温,盐环境背景,分析其声速场特性,给出海水声速的平面,垂及断面分布,也给出了本海域海水声速跃层深度,厚度和强度等三大表征值的变化特性及其声道位置。     

养殖牙鲆鳗弧菌疫苗的研究

以牙鲆病原性鳗弧菌M3为抗原,制备了细胞（CV）、细胞－胞外产物（CEV）、脂多糖（LPS）三种疫苗,通过浸泡和注射两种途径对牙鲆进行两次免疫,检测疫苗的免疫保护效果。免疫后4周可检测到免疫组牙鲆具有明显的凝集抗体效价,其中注射组效价显著高于浸泡组,而对照组变化不明显。与对照组相比,免疫组牙鲆获得良好的免疫保护力,其中注射免疫组高于浸泡组。在注射免疫途径中,以CEV的免疫保护效果最好;在浸泡免疫途径中,以CEV和LPS的免疫保护效果最好。结果表明鳗弧菌M3的细胞－胞外产物苗有显著的免疫保护作用。     

Data quality check procedures of an operational coastal ocean monitoring network

Field oceanographic and meteorological data are required for ocean engineering. In response to the requirement of field data, an operational coastal ocean monitoring network was established around Taiwan coast, including nine deep-water data buoys, one shallow-water pile station, 10 coastal weather stations and 10 tide stations. Data quality check procedures are necessary to ensure the accuracy of measurements. This paper presents the data quality check procedures on ocean wave data which includes automatic and manual check procedures. The checking criteria are derived using statistical theory in this paper. In addition, a sea-state-dependent algorithm is presented in this study in order to derive checking criteria of time-continuity check. It is showed to have better performance of picking up suspicious data than using fixed threshold process. This data quality check program is now used on the operational monitoring network.     

不同世代大石花菜切段育苗的生态试验

以大石花菜Gelidium pacificum Okam.的雌配子体、雄配子体和孢子体的切段为材料,进行切段的再生、附着与直立苗培育的辐照度-温度双因子试验及pH和盐度的试验。观测切段培育的死亡率、再生率、附着率、切段平均再生芽数和再生芽长度的变化,还观察了切段培育出直立苗及其生长的情况。结果表明:雌、雄配子体和孢子体在不同辐照度-温度组合以及不同盐度、pH条件下,切段的培育情况没有显著差异。说明三者的生态适应性基本一致。适宜的培育条件是温度17.5～22.5℃,辐照度20～60μEm~(-2)·S~(-1),盐度15～35,pH8.0～8.5。

轻质硬壳海堤断面设计初探

从海堤本身角度看，坝体过重与填料松散是影响其稳定性的主要因素，因此轻质硬壳堤坝是一种很好的选择。该结构采用高强度材料作为外壳，以松散材料填充坝体。根据受力特性、构造要求、施工条件及抗滑稳定条件拟解决结构断面设计的一些基本问题，并结合实例通过对比计算分析，说明轻质硬壳海堤比传统海堤具有更高的整体稳定性。     

Estimation of land surface evapotranspiration over complex terrain based on multi‐spectral remote sensing data

Land surface evapotranspiration (ET) plays an important role in energy and water balances. ET can significantly affect the runoff yield of a basin and the available water resources in mountainous areas. The existing models to estimate ET are typically applicable to plains, and excessive data are required to calculate the surface fluxes accurately. This study established a simple and practical model capable of depicting the surface fluxes, while using relatively less parameters. Considering the complex terrain, solar radiation was corrected by importing a series of topographic factors. The water deficit index, a measure of land surface wetness, was calculated by applying the f_c (vegetation fractional cover)‐T_rad (land surface temperature) framework in the two‐source trapezoid model for evapotranspiration model to mountainous areas after corrections of temperature based on altitude variations. The model was successfully applied to the Kaidu River Basin, a basin with few gauges located in the east Tien Shan Mountains of China. Based on the time scale extensions, ET was analyzed at different time scales from 2000 to 2013. The results demonstrated that the corrected solar radiation and water deficit index were reasonably distributed in space and that this model is applicable to ungauged catchments, such as the Kaidu River Basin.
