Their cross sectional distribution patterns in relation to the river channel morphologies were examined by using shipmounted ADCP (Acoustic Doppler Current Profiler) instrument.


The launching of such a ship into an Earth orbit or beyond by a large nuclear explosion in an underground cavity is sketched out in the second section of the paper, and finally we consider a hypothetical Mars mission based on these concepts.


In the threedimensional problem the case is studied when the normal stress is concentrated on a segment of a straight line of length 2l, which can replace a ship moving along a straight course with the constant velocity U.

Analytical method of capsizing probability in the time domain for ships in the random beam seas


The methods for constructing safe basins of ships and predicting their survival probability in random waves were studied.


The nonlinear differential equation of the rolling motion of ships in random beam seas was established considering nonlinear damping, nonlinear restoring moment, and random waves.


The random rolling differential equation was solved in the time domain by applying the harmonic acceleration method and by synthetically considering the instantaneous state of ships and the narrowband wave energy spectrum.


The numerical simulation of random capsizing course was brought forward, the safe basins were constructed for safe navigation, and the survival probabilities of ships were calculated.

ROLE OF INTERMEDIARY BIOMARKERS IN DETERMINING THE ANTICANCER EFFICACY OF MARINE COMPOUNDS


In the present study, two of the probable an umor marine compounds, manzamine A and sarcophine, were screened using benzo[a]pyrene (BP)derived DNA adduct formation in MCF7 cells as intermediary biomarker.


The results show that low concentrations of NO were selfproduced by marine algae during the exponential growth period and were about nmol/L level.


The NO threshold concentration exists according to the influence of exogenous NO on the marine phytoplankton growth.

 The paper describes the surface design of ship hull forms with a computer. According to principal dimensions and ship form coefficients, and consulting parent ships or sketches of contour lines of the design ship, the hull surface is cut into several surface patches which are defined by the bicubic parametric equations. The surface patches must be continuous at the positions and tangent planes. A fair, artistic and practical ship surface is fomed by the linking up of the surface patches and by suitable modification... The paper describes the surface design of ship hull forms with a computer. According to principal dimensions and ship form coefficients, and consulting parent ships or sketches of contour lines of the design ship, the hull surface is cut into several surface patches which are defined by the bicubic parametric equations. The surface patches must be continuous at the positions and tangent planes. A fair, artistic and practical ship surface is fomed by the linking up of the surface patches and by suitable modification with a set of weighting factors. Ship's lines that may satisfy the original hydrostatic properties such as prismatic coefficients, longitudinal center of bouyancy, etc can be obtained. These ship lines can be selectively adopted by naval architects in their practical work.  本文提出了用电子计算机作船体曲面设计的方法。它根据已定船舶主要尺度和船型系数,参照母型船或设计船的轮廓草图,把船体线型分成若干块曲面片。曲面片用3×3次双参数曲面方程表示。曲面片之间要满足位置连续、切平面连续,然后并接起来,这样便能得到光顺、美观、实用的船体线型。通过一组正权因子的适当调正,可得到满足棱形系数和纵向浮心位置等静力性能要求的船体线型,供造船设计师选择使用。  According to the characteristics of graphs in ship drafting and the capability of the computer system, this article introduces a method for creating automatic plotting program system. For regular graphs, the plotting program set is built up upon level structure of subprograms; for diagrams of curves with more data, such as lines plan and Benjean's diagrams of curves, cubic spline is used to encode and calculate these curve diagrams, and then the whole calculated coordinate value is converted into plotting vector...

For regular graphs, the plotting program set is built up upon level structure of subprograms; for diagrams of curves with more data, such as lines plan and Benjean's diagrams of curves, cubic spline is used to encode and calculate these curve diagrams, and then the whole calculated coordinate value is converted into plotting vector elements to be stored as data file for future use. At the same time, the vector elements are inputted into the plotter for drawing. It has been proved in practice that this method is properly effective with a result of time saving and graphs smoothing.  针对船舶制图中图型的特点和计算机系统的能力,本文介绍了建立自动绘图程序的方法。对于有规则的图形,用子程序分层结构,建立绘图程序组;对于船的型线图、庞勤曲线图等数据较多的曲线图,利用三次样条加密计算,再把计算座标值全部转成绘图矢元,作数据文件保存,以便再用。同时把矢元一次传到绘图仪进行绘图。这样既省时间,图形也较光顺。实践证明,此法效果良好。  Acoustic simulation is a part of marine engine room simulation. This paper recommends two methods of using a microcomputer to simulate the engine room's acoustics. Experiments are carried out to show that the results are satisfactory.  船舶机舱音响的模拟是船舶模拟训练的组成部分.本文介绍了用微型计算机进行音响模拟的两种方法,并对实验结果作了分析.   << 更多相关文摘
