Orpheus outplayed and outsang the sirens and dispelled their powers, at which point they either were transformed into the three small islands on the coast, or threw themselves into the sea, washing up on nearby shores: Parthenope at the isle of Megaride in Naples, where the Egg Castle now stands, thus giving her name to the original city; Leucosia, farther south (Punta Licosa is the tip of the southern end of the Gulf of Salerno); and the siren Ligeia still farther south along the 17Calabrian coast near what is, today, 18Lamezia Terme.

无论是音乐演奏还是歌唱方面，俄耳甫斯都胜于塞壬，于是他解除了她们的魔力。于是，她们摇身变成了海岸边的三个小岛；或者说她们纵身跳入大海，被冲到了附近的岸边：帕耳忒诺珀到了那不勒斯的马家里德，也就是现在"蛋城堡"耸立的地方，那不勒斯城的原名就源自她的名字；而路科西亚到了更南的地方(利科萨角正是在萨莱诺湾的最南角)；塞壬利盖娅则到了比利科萨角还要远的南边——卡拉布里亚海岸，靠近今天的拉默齐亚。

Digital simulation results show that when a step change in firing angle occurs, the first positive half-cycle time of VC will change suddenly and the subsequent electromagnetic transients appearing in the TCSC circuit will lead to overshoot and oscillations in the TCSC impedance. The range and duration of the oscillation will depend on the synchronization modes used and the manner in which the step change is introduced.

发现脉冲触发角阶跃变小时，电容电压的周期时间也突然变小，使得TCSC的导通角不会随着触发角的阶跃变化而发生突变，而是经过一个振荡过程逐渐达到稳态值，进一步揭示了电容电压同步方式下阻抗阶跃特性会出现过冲和振荡现象的原因。

Furthermore, the forming die can realize single punch extrusion according to different die carriers and equipment, double punch extrusion in opposite directions, as well as the extrusion of the helical cylindrical gear with big helix angle.

本发明结构简单，易于制造、安装，可根据不同模架和设备实现单个冲头挤压，也可实现两个冲头对向挤压；可以实现大螺旋角齿轮的挤压；成形力小，下料精度要求低。

The study we have performed demonstrated that the main roof first broke with asymmetry character; gully mining-induced slope was divided into multilateral blocks by surface advance cracks. Furthermore, multilateral blocks rotated and subsided by the function of extrusion and friction between the broken rock block above the goaf and the rock mass advance the coalface.

冲沟坡体下开采时，基本顶初次破断具有不对称性；冲沟采动坡体被地表超前裂隙切割成多边块状，并在两侧坡体的夹持摩擦作用下缓慢回转下沉；相同地质条件下，坡角越大，采动坡体对工作面矿压影响越大。

The reason of low system efficiency of the mechanical lifting is: unavailable match between transformer and asynchronous motor with large capacity of equipment and large self-consumption; large average no load less of Y series electrical machinery (31.4% of the total oilfield electrical machinery) with 2.86kw; limited adjustable extent of stroke of the electrical machinery in low-liquid produced wells with minimum value of 4 times per minute for limitation of minimum rotation of the electrical machinery and minimum arc of contact of pulley. Energy consumption will be waste for 1 to 1.5 times per minute is enough.

分析显示，造成抽油机系统效率低的原因主要是：变压器与异步电动机之间匹配方式不合理，设备容量大，自身损耗大；占油田电机总量31.4%的Y系列电机的平均空载损耗大，为2.86kW；低产液井电机的冲次可调范围有限，受电机最低转度和皮带轮最小包角限制，其最小冲次仅可调到4次／min，但1~1.5次／min的冲次即可满足生产需要，造成能耗浪费。
