喷射搅浆法  [PDF]
姚满堂
地质与勘探 , 1974,
Abstract: 钻探泥浆的搅拌,一般都用搅拌机.但在山顶陡坡的地方打钻,平地盘的代价很高,为了节省地盘和节约设备搬迁的运输量,我队在1971年开始试用喷射搅浆法,代替搅拌机搅浆.所搅泥浆质量同机械搅拌的一样.操作方法:准备容积1立米的铁水箱1或2个,把粘土按比例装入一个水箱中.每100公斤清水,约加30公斤粘土,具体配比还要根据钻孔实际情况所需泥浆的粘度而定.备足所需

Songklanakarin Journal of Science and Technology , 2010,
Abstract: A submarine robot is a semi-autonomous submarine robot used mainly for marine environmental research. We aim todevelop a low cost, semi-autonomous submarine robot which is able to travel underwater. The robot’s structure was designedand patented using a novel idea of the diving system employing a volume adjustment mechanism to vary the robot’s density.A light weight, flexibility and small structure provided by PVC can be used to construct the torpedo-liked shape robot.Hydraulic seal and O-ring rubbers are used to prevent water leaking. This robot is controlled by a wired communicationsystem.
Submarine neutrino communication  [PDF]
Patrick Huber
Physics , 2009, DOI: 10.1016/j.physletb.2010.08.003
Abstract: We discuss the possibility to use a high energy neutrino beam from a muon storage ring to provide one way communication with a submerged submarine. Neutrino interactions produce muons which can be detected either, directly when they pass through the submarine or by their emission of Cerenkov light in sea water, which, in turn, can be exploited with sensitive photo detectors. Due to the very high neutrino flux from a muon storage ring, it is sufficient to mount either detection system directly onto the hull of the submersible. The achievable data transfer rates compare favorable with existing technologies and do allow for a communication at the usual speed and depth of submarines.
Dynamic and instability of submarine avalanches  [PDF]
F. Malloggi,J. Lanuza,B. Andreotti,E. Clément
Physics , 2005,
Abstract: We perform a laboratory-scale experiment of submarine avalanches on a rough inclined plane. A sediment layer is prepared and thereafter tilted up to an angle lower than the spontaneous avalanche angle. The sediment is scrapped until an avalanche is triggered. Based on the stability diagram of the sediment layer, we investigate different structures for the avalanche front dynamics. First we see a straight front descending the slope, and then a transverse instability occurs. Eventually, a fingering instability shows up similar to rivulets appearing for a viscous fluid flowing down an incline. The mechanisms leading to this new instability and the wavelength selection are discussed.
Primary Initiation of Submarine Canyons  [PDF]
J. Marvin Herndon
Physics , 2011,
Abstract: The discovery of close-to-star gas-giant exo-planets lends support to the idea of Earth's origin as a Jupiter-like gas-giant and to the consequences of its compression, including whole-Earth decompression dynamics that gives rise, without requiring mantle convection, to the myriad measurements and observations whose descriptions are attributed to plate tectonics. I propose here another, unanticipated consequence of whole-Earth decompression dynamics: namely, a specific, dominant, non-erosion, underlying initiation-mechanism precursor for submarine canyons that follows as a direct consequence of Earth's early origin as a Jupiter-like gas-giant.
基于混合粒子群算法的沥青转运车螺旋搅料器模型及仿真  [PDF]

科技导报 , 2010,
Abstract: 为解决沥青转运车螺旋搅料器搅拌特性建模困难的问题,运用人工智能理论建立了以螺距、叶片半径为输入,沥青混合料的离析率为输出的神经网络模型。为克服BP算法与粒子群算法(PSO)的缺陷,将L-M算法与PSO算法相融合的混合粒子群算法PSOLM应用于该神经网络模型的学习算法中。为避免PSOLM算法在全局最优值附近的搜索过程变慢,采用一种从PSO搜索到L-M搜索的启发式算法。仿真试验结果表明,与BP算法、PSOBP算法相比,该算法不仅对螺旋搅料器模型的精度和建模的效率有显著的提高,而且改善了PSO算法的全局寻优能力,提高了算法的收敛速度和计算精度,避免了PSO算法早熟现象的出现,为螺旋搅料器搅拌特性的建模提供一条新的有效解决途径。

Abstract: 不考虑齿间啮合功率损失和挤压功率损失因素,直接使用实验的方法对单独运转的直齿轮进行搅油功率损失测定。首先,在对影响搅油功率损失的齿轮模数、齿数、齿宽、转速、没齿深度比以及润滑油的密度、粘度等多个参数进行研究的基础上,使用流体力学π定理得到直齿轮搅油功率损失普遍公式。然后进行了各种参数依次变化的分组实验,根据数据拟合计算确定了普遍公式中的待定系数,同时对直齿轮搅油的现象及各参数对搅油功率损失的影响进行了分析。结果表明,实验获得的拟合公式能在中低转速条件下有效预测搅油功率损失数值。本文结果可为后续一对齿轮啮合时的搅油功率损失计算与测定提供了理论基础和方法依据。
Churning power loss of single operating spur grar was directely measured through experiment, without taking into account the inter-tooth meshing power loss and the extrusion power loss. First, general formula of a single spur gear power loss was obtained by using π theorem in fluid mechanics, based on the analysis of influencing factors, including module of gear, number of teeth, gear facewidth, rotation speed, oil immersion depth of gear and lubricant density and viscosity etc. Second, grouping experiment for above-mentioned influencing factors was carried out. The undetermined coefficients in general formula were determined based on the data fitting calculation. At the same time, the phenomenon of spur gear churning and the influence of above parameters on the churning power loss were analyzed. Results shaow that spur gear churning power loss value can be predicted effectively by using the fitting formula under condition of low and medium rotation speed. Above results provide the theoretical basis and method for further calculation and measurement of a pair of gears churning power loss in meshing gears

Sound effects as a genre-defining factor in submarine films  [cached]
Linda Maria Koldau
MedieKultur : Journal of Media and Communication Research , 2010,
Abstract: Submarine films can be regarded as a genre with a specific semantic and syntactical structure that heavily depends on the acoustemological nature of submarine warfare. The sound design in submarine films therefore has decisive dramatic and emotive functions. The article presents the sound effects most specific to submarine films and discusses the creative potential they offer both as diegetic sounds bound to submarine existence and as emotive cues with an immediate effect on the audience.
