Newton construes the true motion of an object, as opposed to its merely "apparent" motion, not in terms of its change in relations to other objects, as Descartes had done in his Principles , but in terms of its change of absolute place (Janiak 2008, chapter five).
牛顿的解释为对象的真实运动,而不是它的只是&表面&的议案,而不是其在关系变化方面的其他对象,如笛卡尔在他的原则进行,但在其绝对位置的变化范围(张奕2008年,第五章)。

The email stated that according to the ARECIBO Telescope data that it keeps changing, and if fact it has changed so much that according to this NASA employee, NASA thinks that it may be a 50/50 chance of possibly hitting Earth and NASA does not want to tell us because if its a 50/50 chance and you tell people that something this large is going to hit the pacific or atlantic ocean and everybody evacuates all the coastal areas and it doesnt hit, people will be really, really furious, so say the least!
电子邮件说根据 ARECIBO 射电望远镜的数据,它不断变化,并且如果面对它那么多的变化与这个NASA雇员一致,NASA认为撞击地球的可能性是50/50而且NASA不愿意告诉我们,因为如果50/50的可能性而且你们告诉人们这大事是去撞击太平洋或者大西洋而且每个人全部沿海岸区撤走而且它不撞击,人们将是真正地,真正地狂怒,至少这样说!

Through the topographical survey, literature research and analysis of the remote sensing images, we shall emphasize on the five factors of water conservancy, water flow, streams, water retaining and water utilization in the upper reaches of the river, which are interacted and interplayed.
研究结果表明,漓江为雨源性河流,降雨时空分配极不均匀,70%的降雨量集中在漓江上游区域,全年62.7%降雨量和降雨时间集中在四个月内(即4~7月),最大的日降雨量可达415.8mm;降雨量最小的月份出现在12月至翌年1月,仅100~110mm,占全年降雨量的6%左右,由此直接影响流域河川径流季节性的变化,造成洪水期和枯水期现象,周期性水量的变化是不为人们意志改变的一种自然规律。

In "Rebirth", each work is covered with a single color. Again, without closely examining these paintings, viewers would not notice the subtle changes in colors and the various interplays of multi-layered of lights and darks. However, one might finally realize that these paintings were executed under natural lighting in the artist's studio, and it is nearly impossible to detect all the subtleties and nuances occurring in them when viewing under the gallery's artificial lighting.
全画面笼罩在单一的色相中,如果没有同样的凝神关注,观者是不会发现色晕中不断变化著的微妙色差,以及虚虚实实的光影交错;而且当发现─这些作品是作者维持著画室白天的光线作画所完成,观者想在展览现场的人工照明光线下看出所有的色感变化,大概还做不到呢!

The compound solution performs as pseudo-fictile fluid, and its visual viscosity is reduced when the shearing velocity increases. The higher the cationic degree of CPAM, the more apparent the rarefying behavior of the polymer-surfactant complex, but it still is pseudo-fictile fluid. In addition, such factors as the molecular weight of CPAM, temperature and PH value etc, have different effect on the properties of the mixed solution, including its visual viscosity, conductivity, rheological behavior and so on.
CPAM/SDS复合体系的表观粘度随剪切速率的增大而下降,即具有剪切变稀行为的特性,表现为拟塑性流体:CPAM的阳离子度越高,它与SDS形成复合体系剪切变稀的行为越明显,但体系的流动类型不发生变化,仍为拟塑性;随着CPAM分子量的提高,复合体系的非牛顿性增强;温度的升高将导致复合体系的粘度显著降低,非牛顿性减弱;对于SDS用量低于等电荷当量的复合体系,pH值的变化对其流变性的影响不显著。

In different conditions on fluidized state and stability of conical fluidized bed. The conlusions are: the conical angel of the conical fluidized bed is 20°, the fluidized state havesmall difference in conical distributor and distributor plate. The angle of conical bed increase,the fluidized state will have big difference. The angle is 60°and the conical as distributor, themass of fluidized is less, the most of material is the bottom of conical bed. The effect ofdistributor plate is much better than the conical distributor. Sawdust and rice hull can fluidize.The annular gap of conical distributor different, the angle of conical bed is same, the fluidizedquality of 10mm annular gap is better than the other conical distributors. The annular gap ismore wide, the conical bed have more slugging phenomenon and the pressure fluctuate is turnbig.In the experiment the flow of 2%and 4%distributor plates don\'t easy to control, becausethe pressure is very big and the pressure fluctuate of conical bed is too big.
在不同的条件下对锥形床的流化状态和稳定性进行了研究,结果得出:锥形床的锥角为20度时,分布锥和分布板的流化状态相差不明显,随着锥形床锥角的增大,分布锥和分布板的流化现象会出现明显的变化,锥形床锥角越大,分布锥的流化状态变化越明显,流化的的物料越少,大量物料都聚集在锥形床底部,而分布板在加料量少的情况下,能流化起来。10mm、15mm和20mm环隙分布锥在锥形床锥角相同条件下,10mm环隙分布锥的流化质量要好于其它两个分布锥,环隙越大越容易出现腾涌现象的产生,压降波动范围增大。2%、4%和6%开孔率分布板在本实验测定时,2%和4%开孔率分布板的流量不容易调节,同时产生的压降波动范围也很大,比较来说,6%开孔率分布板流化质量好些。

In order to improve the efficiency, an implementing scheme (according to the distribution of strain energy density) was suggested when to consider the fact that the high gradient usually appears only in a very local region, especially in the case of huge amount of computation. All programming has been finished on the platform of commercial codes Mathmatica and Fortran.4. A number of numerical examples and applications were presented to verify the proposed Bezier-Based Element Method. The engineering cases include: the belt die for diamond synthesize, the main frame of wire-rounded press, the hydraulic cylinder of open die forging press. The numerical results show that the BBEM has some good performances.
通过大量的数值算例来考证所构建的各种类型单元,并应用于人造金刚石年轮模具、钢丝缠绕预应力机架和液压机工作缸等实际问题的结构分析;结果表明:所构建的Bezier耦合单元具有描述较大梯度变化场(如位移场、应力应变场等)的能力,该方法不改变单元的大小和形状,保持单元的自由度数不变,而通过调节中间可动节点的位置改变单元内部的场分布,只需少量单元即可较精确地模拟较大的梯度变化;可为有效求解高梯度问题提供新思路,对实际工程应用具有重要意义。
