不稳的

according to the users′ actually demand for uninterruptible power supply for loads,the internal structure of digital generator is analysed and the reason for its uninterruptible function can′t be achieved.a design of the uninterrupted power supply system which transformed from the digital generator is proposed.the system uses the inverter of generators,ac through inverter for loads,at the same time,charges the battery as ac is normal.inverter the battery dc converters to ac for load,meanwhile,starting generator,when power failure.the system applies uninterruptible power for load,whether the ac is normal or abnormal,and design voltage and frequency stabilization,output zero-interrupted,battery charging and discharging management.without requiring purchase an uninterruptible power supply separately,this design can avoid duplication of investment and wasting of resources.

快速安全提高汽轮发电机转子检修质量。。。摘要：针对用户对负载供电不间断的实际需求，分析了数码发电机的内部结构及其不能实现供电的不间断性能的原因，提出一种由数码发电机改造组成的交流不间断供电系统的设计方法。该设计利用发电机内部的逆变器，在市电正常时，由市电经过逆变器给负载供电，同时给蓄电池充电；在市电断电时，一边启动发电机，一边由蓄电池的直流电通过逆变器转换成交流电供负载使用，实现无论市电正常还是异常，系统对负载提供不间断电源。设计对市电进行稳压、稳频、输出零切换、蓄电池的充放电管理等新功能。此设计无需单独购买不间断电源，避免重复投资和资源浪费。

METHODS: From January 2001 to December 2008, 87 cases of Tile C type pelvic fracture were treated with the percutaneous iliosacral articulation screws and pelvis external fixation, and 39 cases treated through the anterior and/or posterior approach were selected as control group.

选择2001-01/2008-12广东省人民医院骨科收治采用经皮骶髂螺钉固定技术治疗的不稳定型骨盆骨折患者48例作为实验组。收集同期广东省人民医院科骨科收治行开放前路和/或后路手术治疗的不稳定型骨盆骨折患者39例作为对照组。

In this paper, the analytical solutions of reservoir pressure in Laplace space are developed for planar linear flow and radial flow under the condition of constant pressure at inner and outer boundaries, and the pressure distribution curves in some point in the reservoir are obtained using Stehfest numerical inversion algorithm of Laplace transforms.

本文在内、外边界定压的条件下得到了平面单向流和平面径向流两种渗流形式在拉氏空间的解析解，利用Ste hfest数值反演方法给出了地层各点的压力分布曲线，由这些曲线可以清楚地看到流体的流动由不稳态流向稳态流过渡以及最后达到稳态流的过程。

In recent years, the county up and down firmly establish the "animal husbandry instability instability in the whole county, not the rich herders, the county is not rich" ideas, has always been to increase efficiency of agriculture and animal husbandry, farmers and herdsmen in rural incomes and maintain stability as the work of farmers and village enterprise, has invested 2,480 million yuan to build one or two bases and livestock disaster insurance camel, cashmere goats base, completed the demonstration county animal husbandry and the "three" of training works, the new on the restoration and protection of natural vegetation projects, ban works, the completion of 3 million mu of artificial grass, aqueduct built five more than eighty kilometers, 22 kilometers of flood control dams, the new hit 12 motor-pumped wells, construction of the drug bath, flood pool 20, the completion of fencing 41.7 million mu of grassland, built to high standards SHELTER 20, control the "three" of 57.7 million mu of grassland, improved herd face up to 82%, the proportion of school-age dams more than 56%.
