The use of assets for impairment adjustment of profits According to the Ministry of Finance, in 1999 and 2001 respectively, the implementation of the new accounting system, would require a total of eight Provision for impairment, in the Provision for impairment of the year, profit was not affected, and the year after back-impairment Preparations that can increase profits, some listed companies to take full advantage of this policy, previously extracted large amounts of impairment, and after a variety of meaning that those who have the impairment of assets each year restoration of the original value, so back - Have mentioned impairment, inflated profits, as for the impairment of assets and revaluation itself is difficult to define a subjective issue, after preparations for impairment from increased profits from the source.

九、利用资产减值准备调节利润根据财政部的规定，在1999年和2001年分别执行新的会计制度，共需计提八项减值准备，在计提减值准备的当年，不影响当年利润，而以后年度冲回减值准备时则可以增加当年利润，某些上市公司为充分利用这一政策，先前提取大额减值准备，而以后以各种各义说明那些已减值资产逐年恢复了原有价值，因此冲回已提减值准备，虚增利润，至于资产的减值和升值本来就是一个难以界定的主观问题，提取减值准备为以后增加利润提取了来源。

When the gas flux is constant, the ratio of reduced resistance is improved with the increase of the water stream velocity. However, the relationship between the gas flux and the ratio of reduced resistance is more complex. When the water stream velocity is constant, if the gas flux is small in contrast, the effectiveness of reduced resistance is not obvious. But when the gas flux increased, the jetted gas will form """"archform"""" which will augment the shape resistance. In this condition, resistance could not be reduced and could even be increased, if the gas flux continues to be increased. So that there needs setting a baffle called step, which introduces the jetted gas into the turbulence boundary layer. In this case, the shape resistance may be fairly great. Besides, the waterline of model has also some effect on the ratio of reduced resistance, which acts on the size of wave. If waterline is deep, the wave could not affect the deployment of microbubble layer, so there is almost no effect on ratio of reduced resistance. However, the wave would affect distributing of microbubble layer under the model so that the gas could leak out from the two sides of model and directly affect the ratio of reduce resistance if the waterline is very small. Whether installing the dashplate or not has also the great influence on the effectiveness the ratio of reduced resistance. From the results of experiment, conclusion is that adding dashplate will greatly improve the effectiveness of reduced resistance.

当喷气量一定时，水流速度增大，减阻率提高；喷气量与减阻率之间的关系比较复杂，速度一定时，如果喷气量较小，减阻效果就比较差，但当喷气量增大的话，喷射出的气体就会形成一个&拱度&，增加了船模的形状阻力，在这种情况下最好采取断阶喷气，把气体引入到湍流边界层中，在这种情况下，船模的形状阻力比较大；船模的吃水对减阻率也有一定的影响，主要表现在波浪大小上，如果吃水较深，波浪影响不到微气泡层的分布，对减阻率不会造成太大影响，如果吃水较浅，波浪就会影响到微气泡层在船模底部的覆盖情况，可能会有部分微气泡从船模两侧泄漏，这样就直接影响到了减阻效果；是否安装压浪板，对减阻率也有较大的影响，从试验结果可以看出，在船模尾部加设了压浪板时，减阻效果明显得到改善。

The agitation power consumptions in boiling systems decrease uniformly with the increase of agitation speed, whereas the relative power demand (RPD-the ratio of agitation power input of HEDT for gassed system to that for ungassed system and under the same agitation speed) can maintain at a high level for high gas loadings even when the impeller is operating with a high impeller tip speed. The gas hold-up in the boiling system is much lower than that in the cold gassed system, and the gas hold-up in boiling system increases at first and then decreases with the increase of the agitation power consumption per liquid mass P(subscript m. It implies that the boiling three-phase system has a maximum gas hold-up point. The changes of nucleation site of vapour bubble and the character of suspension of the solid particles with the rotational speed of the impeller are responsible for those behaviors mentioned.

在沸腾条件下，搅拌功率消耗随着搅拌转速的增加有所下降，但HEDT桨具有较高的载气能力，即使在高叶端线速度下，相对功率消耗仍能保持在较高的水平；沸腾体系的气含率随单位质量流体输入功率的增加表现出先增后减的规律，即存在气含率的极大值，蒸汽成核位置和固体颗粒悬浮特性随搅拌功率增加而改变是造成上述行为的主要原因；沸腾体系中的气含率远远低于常温通空气体系。

Geometrical and physical parameters of components of the absorber in the virtual prototype follow from those technical data of a specific passenger car. Bench tests are conducted and a series of experimental results have been obtained by the MTS absorber test machine for the damping force-velocity which can be imposed in the virtual prototype for dynamic simulation. The piecewise, the hysteretic looped and the abnormal looped hysteretic force-velocity curves for the absorbers are, respectively, input into the prototype.

减振器阻尼力—速度特性是根据MTS减振器特性试验机试验结果，通过分段拟合，分别以分段线性、迟滞环和迟滞环畸变情况输入虚拟样机进行仿真分析，试验及仿真结果比较说明：减振器速度外特性采用迟滞环非线性，比采用双线性化模型更接近试验结果，能够更合理地解释试验现象；减振器阻尼力速度特性曲线出现畸变，如在复原行程初期迟滞特性曲线出现交叉现象，可以引发减振器系统动力特性的高频振动成分增加。

The traditional algorithms of classification are no longer suitable because of the effect of the concept drift in data streaming. The research on fast and stable data mining systems with high accuracy has become more valuable in both theory and practice. The effect of low frequency concepts on time and space performance is studied and an LFCR algorithm is proposed in this paper, which reduces the low frequency concept with some mechanisms. The extensive experimental study shows that LFCR has improved performance in classification in comparison with RePro.

由于数据流中概念漂移现象的影响，使得传统的分类方法不再适用，因此研究快速、精确及稳定的数据流挖掘方法和系统具有较高的理论和应用价值；文章研究了基于频度的概念漂移中低频概念对分类时空性能的影响，提出了对其中的低频概念进行消减的算法，实验表明LFCR算法比RePro算法有更好的分类性能。

Punting 溅出的水花儿: It might be a good option to take the baseline as the 5th condition, then randomise all the 5 conditions together to produce an experimental order.

一 可以将条件间的baseline缩短一些，比如减为6s，而两大组之间可以保留一个与任务时间相当的baseline 处理的时候可以把条件之间的baseline作为另外一种条件(或者直接算作baseline也影响不大)这算是两种方案的折衷
