Based on the data on scour around large diameter cylinders exposed to waves and currents , effects of every kind of sea enviromental parameters on maximum scour depth are analyzed and guided by dimensional analysis and multidimensional linear regression , an equation is given to compute maximum scour depth around large diameter cylinders in combined waves and currents . compared with some other equations , this equation is more accrete , simpler and clearer and the compute d results are in good agreement with experimental ones 本论文主要是在总结国内外研究成果基础上，从波浪与水流共同作用下海床上直立大直径圆柱建筑物周围的局部冲刷机理出发，研究和探讨了圆柱周围的冲淤形态；分析各种海洋环境参数对最大冲刷深度的影响，并利用已取得的实验资料，采用量纲分析原理和多元线性回归分析方法，建立一个波流共同作用下海床上直立大直径圆柱建筑物周围的最大冲刷深度计算公式。
The focal point of this paper is to inquire into the possibility of constructing a new mode of urban management system of the reciprocal direction ' s style through the innovation of system in community construction , and thus government and society can interact with each other , government administration and community autonomy can cooperate , accrete , and optimize with each other , which by some existing community management mode ' s comparison 随着市场经济和现代城市的发展，这种体制的弊端日益突出。社区管理方式变革势在必行。本文的重点是通过对现有的几种社区管理模式的介绍与比较，探讨建构一种政府与社会双向互动、政府管理与社区自治协作共生、互为优化的双向导向型的新型城市社区管理模式。
Such a process can take place in the low mass x - ray binary systems where the mass transfer from the companion to the neutron star can be larger than 0 . 5 solar masses . if the neutron star in the low mass x - ray binary accretes the matter , the central densities can reach to a state that strange - matter seeds are formed in the interiors of the star 在这个系统内，中子星可能会吞噬超过0 . 5个太阳质量的伴星物质，当中子星吸收了这些物质后，中心的密度会增加至足以产生奇异物质种子，这些种子会开始吞噬四周的中子物质，释放出大量中微子和反中微子，令星体冷却。
The focal point of this paper is to inquire into the possibility of constructing a new mode of urban management system at the grassroots level through the innovation of system hi community construction , and thus government and society can interact with each other , government administration and community autonomy can cooperate , accrete , and optimize with each other 本文的重点是探讨通过社区建设中的体制创新，建构一种政府与社会双向互动、政府管理与社区自治协作共生、互为优化的新型城市基层管理体制。这种管理体制是对与传统计划经济体制相适应的城市管理体制的改革和创新。
All kinds of testing result and analysis indicated that keep the same aluminum concentration ; the range of current density getting good aluminum coating can be accreted with the increased of aluminum chloride concentration . when the molar ratio of alcb and lialrj is 5 , the current density can be 10a / dm2 各种测试结果和分析表明，在总的铝浓度不变的情况下，获得良好镀层所使用的电流密度范围可随氯化铝浓度的增加而增大，当alcl _ 3与lialh _ 4的摩尔比为5时，可使用的电流密度达到10a dm ~ 2 。
The designed base - station and substation ( dolly controler ) both have infrared interface which can beam and receive infrared signal . by accreting the beaming power , one base - station can control 64 set of substations at mostthe base - station and master pc computer is connected with rs - 485 interface , this fullfils the demand of long - distance and high - speed commnication 通过增大发射功率，一台基站最多可控制64台从站。基站与上位pc机之间采用rs - 485接口进行通信，可以满足远距离高速通信的要求。
Result of numerical simulation shows that the grads of continuous phase " s velocities decreases with the presence of microbubble of which the diameter is 100 / / w , the profiles of air volume fraction in the boundary layers is similar to triangle or echelon , affected by interaction among the particle , there is a saturated air fraction , within the scope of saturated air fraction , increasing the air injection ratio can accrete the friction reduction ratio , under the condition of same air injection ratio , the free - steam velocity is larger , the effect of friction reduction is worse 计算结果表明，直径为100 m的微气泡能减小近壁面连续相的速度梯度；微气泡在边界层中的浓度分布近似为三角形或梯形分布；受粒子间相互作用的影响，存在一饱和浓度；减阻率随喷气量的增大而增大，直至饱和喷气量，此后，增大喷气量，壁面摩擦阻力变化不大；相同喷气量下，来流速度越大，减阻率越低。
The temperature range of quasisoft x - ray sources falls just right for an accreting black hole that is more massive than a stellar - mass black hole . however , we should be cautioned that in principle , the low temperatures of many quasisoft x - ray sources can be explained by stellar - mass black holes , neutron stars , and even white dwarfs under very specific physical conditions 就以类软射线源的温度范围来说，虽然它完全符合那些比恒星型黑洞更大的吸积黑洞，但有一点不能忽略，就是这个温度在理论上也可以是由恒星型黑洞中子星甚至白矮星在一些特殊物理情况下产生。
Black holes are invisible by definition , yet the gas and dust falling into a black hole are heated to high temperatures and glow furiously . if there is a companion star orbiting around a black hole , astronomers can investigate the central black hole by examining the accreting matters from the nearby companion star 顾名思义，黑洞漆黑一片，目不可见，但其实那些堕入黑洞的气体和尘埃，会因受热而发出炽烈的光芒，因此假如黑洞有伴星的话，天文学家便可透过观测伴星物质流入黑洞时所形成的吸积盘，对中心的吞噬者进行研究。
At the beginning of doing poineering work , president of grand of aid of the song dynasty put forward " join forces goes all out in work , dare try to be the first " , " sincere letter is this , excelsior " , " employee close kin , client comes honour " , " or is not done , or is done best " , " everything is a center with the client " , " good faith cooperates , accrete win - win " wait for a series of principles that manage a plant , manage philosophy basically what conveyed mr song jilong centrally 创业之初，宋济隆董事长就提出了“合力拼搏、敢于争先” 、 “诚信为本、精益求精” 、 “员工至亲、客户至尊” 、 “要么不做，要么就做最好的” 、 “一切以客户为中心” 、 “精诚合作，共生共赢”等一系列治厂原则，集中表达了宋济隆先生的基本经营哲学。
