不流动的

It is impossible to describe this complex flow with a single method. Specially to transition flow, there is no suitable theory. The equation that fits it is Boltzmann equation, but the solution of it is almost impossible.

特别是对于过渡领域的流动，目前尚无完善的理论，与之相对应的数学方程是完全的Boltzmann方程，它是一个非常复杂的非线性的积分-微分方程，除了极其简单的情形，它的求解根本是不可能的。

Numerical simulations were carried out to study the effect of reversible work and viscous dissipation on the heat transfer characteristics of compressible fluid flow in microtubes.

利用数值方法讨论了压力功和粘性耗散对微细光滑管内可压缩流动换热特性的影响，得出以下结论：微细管内 Ec沿管长是变化的，仅依据入口处的 Ec对压力功及粘性耗散的作用进行取舍是不确切的；等热流及等壁温换热条件下的计算结果显示，在入口 Ma及长径比较大时，考虑压力功及粘性耗散时得出的 N u要小于常规尺度管的理论值，在等壁温情况下，甚至出现了热流方向发生变化的情况

In this paper, the FIR low-pass digital filtering method is first introduced for reducing the effects of noise signals in the experiment of velocity measurement of high-temperature flue gas flowing in pipe. The experimental results indicated that, only one peak presents in the cross-correlation graph, which is in good agreement with theoretical analysis result. Secondly, the temperature and pressure pulse signals of the high-temperature flue gas, obtained by thermocouple and pressure sensor, are introduced to explain the applicability of sensor characteristics.

本文介绍在测量管内流动的高温烟气流速的实验中采用FIR低通数字滤波器滤波方法可以排除干扰信号的影响的研究，实验结果证明，经过滤波处理后的信号互相关函数的图形不会出现大小相当的多个峰值，符合理论分析的结果；其次，本文还介绍了用热电偶和压力传感器采集的烟气温度和压力脉动信号，分析了传感器特性对相关测速的适应性。

Wenzhou So when the surplus funds to invest in not only local and only bank deposits, the influx of a place on the disrupted eyes that stare only at the local consumption and investment capacity of the government, was severely hit the head of a wand After the government began to abandon the market economy, competition and capital flows, the basic principles, attempting to use a variety of fallacies, and various non-market administrative means Road erected firewalls, panic in the foreign capital inflow, will market any change Incrimination Wenzhou People in the real estate, rather than a review of the government's forecast of the market and management capabilities.

因此，当温州的盈余资金投资不仅当地，只有银行存款，流入地的破坏眼睛凝视只能在当地消费和投资能力的政府，是严重打击头部的魔杖后政府开始放弃市场经济，竞争和资本流动的基本原则，企图用各种歪理邪说，各种非市场的行政手段道架设防火墙，恐慌的外国资本流入，将市场的任何变化归罪温州人在房地产，而不是审查政府的预测，市场和管理能力。

The evolution is not in a way of Darwinism but Lamarckism. The evolution of technology is a process of selection which includes natural and social selection, which means flowing and integration of technology information. The evolution refers to not only the progress, but also stagnation and degeneration.

技术在技术环境中进化，技术环境包括自然环境和人文环境；技术进化具有拉马克式的特征，其要点是用进废退和获得性状的遗传；技术在选择中进化，技术的选择包括自然选择和社会选择两个方面；技术进化意味着技术信息的流动和组合；技术进化不仅仅指技术的进步，还包括技术的退化及技术发展的停滞；技术进化具有多样性；技术进化是不确定的，又可以在一定程度上预测；技术进化是连续进行的，但也表现出突变的特征；技术进化并不意味着技术是有机体。

Barrel is the key part of artillery. In shot process, propellent gas of high pressure and high temperature flows in the tube at a high rate of speed, which brings an upheaval to the temperature field of the composite barrel. As to the composite barrel with metal inner, its poor thermal conductivity is more likely to cause uneven temperature distribution and bigger temperature gradient, to produce improper deformation and to make the work temperature of metal inner rise, all of which will affect the life span of barrel.

身管是火炮的关键部件，在火炮发射过程中，高温、高压的火药燃气在身管内成脉冲式高速流动，使身管受到急剧的加热，引起身管壁内的温度急剧变化，而对于带金属内衬复合材料身管，由于复合材料导热性能较差，更容易引起非均匀温度分布以及较大的温度梯度，产生不合适的变形，也会使身管的金属内衬的工作温度升高，从而使得身管的寿命降低，同时身管的发热会引起其刚度的变化，增大射弹散布。

The function of enclosure was to enable the dispersed fields of a landowner in a single parish to be concentrated without increasing and decreasing in the proportion before and after enclosure; Enclosure was the precondition of the estate structure in the late 19th century, while the main motivation and approach of that was social mentality and estate market; In the estate structure of late 19th century, agent was the main actor to manage the large and middle estates; Landowner, tenant farmer and agricultural labour affected and restricted each other, which was full of tender feelings.

圈地运动的作用只是使土地所有者在单个教区内分散的土地几乎数量不变地集中到一起；小土地所有者不仅没有消失，而且在1780-1832年间圈地进行最为剧烈的时期出现了数量增加的状况；圈地运动为大地产的形成创造了前提，十八、十九世纪土地流动的主要动因和途径则是大众的心态和市场的激励；在19世纪晚期地产结构中，大、中地产的管理主要是通过代理人体系进行有效的运营；地主、农场主、农业工人三者之间相互影响、相互制约，充斥着温情。

Dark Horse's other songs -- recorded during the summer at Chad Kroeger's converted barn studio in Vancouver -- traverse a wide terrain, from the arcing melodic ebb and flow of the first single,"Gotta Be Somebody" and the metallic groove of "Burn It To The Ground" to the heavy riffery of "Something In Your Mouth" and "The Next Go Round" and the inspiring balladry of "You'll Never Be Alone" and I'd Come For You.

& 黑马的其他歌曲-记在今年夏天在乍得克勒格尔的转换谷仓工作室在温哥华-穿越了广泛的地形，从电弧旋律低潮和流动的首支单曲&爱是要有人&和金属槽的&烧地面&的沉重riffery的&东西你的嘴&和&下一页转到回合&和鼓舞人心的民谣的&你将永远不会被孤立&和&我想现在您。

The twin vortex at the tip clearance of hub side and the asymmetric recirculation at wall of inlet duct are also observed. 4 The mass-weighted average of flow parameter at inlet and outlet of every passage of impeller changes with different positions. In addition to the above, with the unsteady method, the head rise, shaft power and efficiency have been predicted well.

再次，采用整机非定常计算准确预测了三种工况下部分流泵的扬程、轴功率和效率；发现了叶轮进出口质量加权平均的速度、压力、动量矩的宏观不变特性；蜗壳内流动的非定常性对部分流泵的外特性有重要的影响。

To readjust China's mode of financing she should consider the following points: First, bringing the inflow of foreign direct investment under control; Next, adopting multiple modes to raise foreign funds in order to keep in accordance with the trends of international financial markets; and then, also emphasis should be laid on keeping the ballance between borrowing and the inflow of foreign direct investment.

根据90年代国际资本流动的特点，利用外资工作就不能只局限于争取贷款和吸收直接投资方面，应当积极探索新的更有效的利用外资形式。国际上流行的债券、股票以及基金等形式的融资方式，对吸收外资行之有效，而中国目前在这些方面正好是个薄弱环节。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
