In the IEEE 50 generators test system, the proposed on-line voltage stability monitoring method is tested, the recursive square-root least squares filter with a forget factor is applied to track the parameters, and the results indicate that it can identify the critical bus effectively so as to realize on-line voltage stability monitoring.

将提出的电压稳定在线监测方法在IEEE 50机测试系统进行了仿真，参数辨识采用递推的带遗忘因子平方根最小二乘算法，结果表明它能有效地识别出电压稳定薄弱节点、实现电压稳定在线监测。

In the past to reduce heat loss and improve the efficiency of furnace oil to save energy expenditure has been the main method, but the application of waste heat recovery technology is a weak link.

以往降低热损失和提高加热炉效率一直是节约油田热能消耗的主要方法，而余热回收技术的应用则是一个薄弱环节。

The research of marsh initiated in the 1960s in our country. However, the study of marsh sedimentation and environmental changes was relatively weak, even though we have done some preliminary works on an approach to the characteristics of sporepollen assemblage of peat in the Holocene and paleoenvironmwent, and formation mechanism and deposition kinetics of peatland since 1990s. But we are lacking in systematic research on gleying marsh, especially on recent short timescale and highresolution sedimentation records of environmental changes. There is a certain disparity in this field compared with lake sedimentation and environmental changes.

我国沼泽研究起步于20 世纪60 年代，期间有关沼泽沉积与环境的研究相对薄弱，90 年代以来虽已在泥炭沼泽孢粉解译全新世环境变化与泥炭沉积动力学方面有初步积累，但对潜育沼泽缺乏系统研究，尤其缺乏近代短时间尺度高分辨率环境变化历史记录研究，这方面与湖泊沉积及其环境演变研究相比已形成一定的差距。

There are only saddle horses and sumpters - and hunting bows and throwing knives/daggers are the only ranged weapons (but more powerful now that armour is weak).

只有鞍马和sumpters -和狩猎弓箭和投掷刀/匕首是唯一的远程武器（但更强大的现在，装甲薄弱）。

The reform is facing so many difficulties and problems and the causations are various, including unenlightened educational notions, poor schooling condition, insufficient teacher resource, lagging testing and evaluation system reform, over-size school class, scattered schooling location, immature teacher training mchanism etc.. Those causations themselves and their interactions badly cumber the rural teaching reform.

造成这些困难和问题的原因主要是受到了教育观念落后、办学条件差、师资力量薄弱、考试与评价制度改革滞后、班额过大、教学点分散、教师培训机制不完善等多方面因素的制约，且这些制约因素相互影响阻碍着农村课程改革。
