In addition to dealing with recovery latency of temporal relation packet loss, ARMER reduces recovery latency of reliable multicast in the condition of spatial relation loss occurs.

ARMER协议引入了"前向的差错检测"机制，实现了主动节点支持的差错检测，有效降低了协议在发生空间相关丢包情况下的差错恢复的延迟。同时，ARMER协议也沿用了主动缓存以支持本地恢复的策略，因此，使得协议可在发生两种类型丢包情况下都维持较小的恢复延迟。

This concept pithily reveals the longstanding, unclear white-collar crime problem, and clearly points out the criminals include not only paupers or persons mentally deranged who commit bloodguilt, crime of pillage, crime of theft, etc., but also the dapper upper-class people who utilize their professions, social status, influence and intelligence technique to commit the worse crimes which can invisibly evade the criminal law and avoid being punished effectively.

这一概念简洁而有力的向人们揭示了长期存在但一直模糊不清的白领犯罪问题，清楚的指出犯罪并不仅仅是穷人或者精神异常的人犯下的杀人、抢劫、盗窃等等，衣冠楚楚的社会上层人士凭借其职业、地位和权势，运用智能手段的犯下的罪行更为严重，同时更加具有隐蔽性和对刑法的规避性，难以得到有效的惩治。

It is available to carry out numerical simulation and fluid dynamic analysis further. Based on Frozen-Rotor Approach and Rotor-Stator Approach, the numerical simulation was carried out in the centrifugal pump and the numerical results showed that the flow in the impeller and volute of centrifugal pump is periodically unsteady. Due to the interaction between impeller and volute the flow is characterized by pressure fluctuations and it is the strongest at impeller outlet and at the vicinity of the tongue. The unsteady pressure fluctuations are also one of the most important reasons to induce vibration and noise. Secondly, the flow field of the volute is characteristic of the vortex flow, and the vortex flow presents very complicated developing process which is creating, increasing and dissipating every now and then. All these lead to very large flow loss in the volute.

采用Frozen-Rotor冻结转子模式和Rotor-Stator滑移界面模式系统开展了不同工况下离心泵内叶轮与蜗壳耦合的定常和非定常流动研究，结果表明由于叶轮与蜗壳的干扰蜗壳进口周向流动的不均匀性是非常强烈的，特别是叶轮与蜗舌间的相互干扰最为强烈，一直影响到叶轮进口和蜗壳扩散管出口的流场；在蜗壳内整个流动是以旋涡形式向出口推进的，并随着包角的变化旋涡表现出十分复杂的产生、发展和耗散的演化过程，导致蜗壳内较大的流动损失。

Also the multi-scale entropy processing and analysis of conductance fluctuating signals acquired by VMEA sensor for five flow patterns with water as the continuous liquid are conducted. The study result indicates that the increase of f o makes oil in water type slug flow occur at lower U sg; for low flow velocity, the continuous liquid inversion occurs at about f o=0.9 and the increase of U sg makes the inversion point move to low oil volume fraction; the multi-scale entropy detail describes the nonlinear dynamic characteristics of oil-gas-water flow patterns and the rate of MSE at low scales sensitively indicates the variation of flow patterns and can act as the efficient criterion of three-phase flow patterns identification.

对水为连续相的5种流型VMEA传感器波动信号进行了多尺度熵分析，研究结果表明：含油率增加可使水包油段塞流在较低气相表观速度下产生；较低流速下的油水相态逆转可发生在油液比为0.9左右，气相流速增加使得逆转点向含油率低的方向偏移；多尺度熵细节可以刻画油气水三相流非线性动力学特性，而低尺度的多尺度熵变化率敏感地反映流型转变，是划分油气水三相流流型的有效准则。

Under these circumstances, when Gnostic schools had passed away with their "conjugations" of Divine powers, and "emanations" from the Supreme unknowable God (the "Deep" and the "Silence") all speculation was thrown into the form of an inquiry touching the "likeness" of the Son to His Father and "sameness" of His Essence.
