Combining with the evolution of congestion control mechanisms, the existed technologies for congestion avoidance and recovery in IP networks are reviewed. The unsolved problems and hot spots in subdiscipline, such as TCP flow control, end to end flow control and enhanced mechanism in intermediate nodes, are summarized, and the advantages and disadvantages of all kinds of schemes for active queue management are emphatically analyzed. Also the paper presents and discusses the drawbacks of heuristic designin...

According to the lowest free energy law of forming steady configuration, it is proved that under the hypotheses of the model the necessary and sufficient condition for the stabilization of magnetic structure is the moment direction of the total saturation magnetization 〓 of a compound should be parallel to that of external magnetic field 〓, and the direction of each sublattice moment 〓 must also be parallel to that of the effective field B〓 acting on the 〓.

根据形成稳定结构的能量最低原理，证明了在该模型的假设条件下，系统磁结构稳定的充要条件是：化合物总的磁化强度m与外磁场B的方向相同，并且各次晶格的磁矩m〓与作用于它们的有效场B〓的方向一致。

And the results indicate that the principal stress directions in study area are mainly NE-SW, and the second substage tectonic twist made the direction deflect from North to East, but the primary direction changed little; tectonic activities during the O〓～S～D stage is some violent, most of the area are under high stresses status, and rock fracture degree is correspondingly higher, as coinciding with the drill cores observation, i.

通过数值分析，模拟了塔中Ⅰ号断裂带和塔中45井三维模拟区O〓灰岩的构造应力场和应变场，结果表明：研究区主应力方向为北东～南西向，第二期的构造扭动使其由北向东发生了一定的偏转，但总的方位变化不大；O〓～S～D时期，塔中地区构造运动较强，研究区大部分处于高应力状态，岩石破裂程度较高，而岩芯观察结果也证实了这一结果，即O〓灰岩地层中早期形成的构造结构面比较发育，单个结构面的规模也较大；C～P时期，岩石的破坏程度较早期有所提高，主要表现在两个方面，一是各局部区岩石的破坏程度普遍有所提高；二是各个级别破裂区的分布范围相应地扩大了；研究区应力分布表现出明显的不均匀性，特别是剪应力，无论是O〓～S～D时期，还是C～P时期，都有很大的差异性，特别是在小断层的端部，剪应力比较集中，而且在断层的两盘，剪应力方向和大小都变化极快。

The intersection of the subvertical foliation adjacent to the porphyroblast rim with an earlier or la ter formed shallowly dipping foliation, which is trapped in the porphyroblast du ring later growth, defines the FIA orientation, and is independent of the moveme nt direction on this foliation.

非洲板块与欧洲板块的相对运动方向和在阿尔卑斯造山作用期间形成的变质产物所指示的运动方向相互一致的事实强有力地表明：FIA是由一种反映板块相对运动的机制形成的。

At last, it forecasts that the future of the land suitability appraisal is the intelligent one.

并预测，未来的土地适宜性评价的发展方向将是智能化的发展方向。

Hydrothermal treatment and pH value swing could shift the micropore distribution of alumina to macroporous direction, and decreased surface areas; the surfactants addition could shift the micropore distribution of alumina to microporous direction, and increase surface areas.

其中pH值交替变动和水热处理使氧化铝微孔分布向大孔方向迁移，比表面降低；加入表面活性剂使氧化铝微孔分布向小孔方向迁移，比表面增加，制备出了低比表面≤150平方公尺g^(-1和高比表面≥250平方公尺g^(-1的大孔容氧化铝载体。

If the straight line linking the nose and tail is defined as the major axis of the aircraft, any aircraft boundary is symmetric about its major axis.

尽管不同用途、不同国度生产的飞机，其形状、大小千差万别，但如果将机首与机尾的中心直线方向定义为飞机的主轴方向，则任何一架飞机的边缘图像都是关于主轴对称的。

The groundwater will drainage to external part of mountain and synclinal limb along the synclinal axis.

分析结果表明，洞室围岩渗透性总体上较弱，且水平方向强于垂直方向，地下水将沿向斜轴向山外和两翼排泄。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.
