Analyses the main causes of condensation occurring at different positions of the envelope , and presents the respective solutions , assuring the swimming gymnasium in normal operation 摘要通过分析围护结构不同部位发生结露的主要原因，有针对性地给出了防结露的解决方案，保证了游泳馆的正常使用。
The percent of larvae expressing lacz gradually increased for various time points after inoculation , but the percent of larvae expressing lacz reduced after 20 hours post inoculation , we thought the infection spots transformed 、从卜又’荞!乡;三、卜率却有所降低，对此，我们分析其原因可能是由于病毒的感染部位发生了转移。
Although regional anesthesia , especially central conduction blockade , produces a favorable sympathectomy and increased limb blood flow , compensatory vasoconstriction in non - anesthetized areas may actually produce vaso - occlusive crises in these areas ( 5 ) 虽然区域麻醉，特别是中枢传导阻滞可产生有效的交感神经阻滞并增加肢体血流，但是非麻醉部位发生代偿性血管收缩，可能使这些部位发生血管阻塞性危象[ 5 ] 。
Gamma knife treatment is a kind of non - invasive and few - invasive treatment . due to precise stereotatic positioning and precise radiotherapy , gamma knife only offers cell - killing effect to tumor but the normal tissues around are frivolously affected because they are only affected by a slight radiation 伽玛刀属于“无创伤”或“微创性”治疗，由于准确的立体定向加以精确的放疗，只对病灶部位发生“毁损”作用而达到治疗目的。
In this thesis , we investigate the fault diagnosis for a hydraulic system with severe nonlinearity under nine different operation conditions using bp neural networks . sensors " fault are considered , which include abrupt parameter changes and slowly parameter drifting 对很多系统而言，当系统性能下降时(非故障引起) ，如果这时系统某一部位发生故障，由于故障受系统自身的非线性特性影响，使故障诊断变的十分困难，从而会引起误报或漏报。
Some important parts for these two vsc - hvdc control systems are designed in detail , especially the structures and parameters of the vsc controllers , as well as the principles for selecting the equivalent inductance of the convertor transformer and the capacitance of the capacitor on the dc side of the vsc . digital simulation using netomac is done to verify the validity of those proposed control strategies . ( 2 ) the operation performance of the vsc - hvdc under some characteristic faulted conditions without any protection measures are studied , and the over - current and over - voltage of the vsc - hvdc during those faults is revealed ( 2 )对vsc - hvdc在没有保护控制的情况下其交流侧、直流侧和vsc内部等部位发生常见较严重故障时的运行特性进行了仿真研究，总结出这些较严重故障可能对vsc - hvdc造成的危害，并针对这些危害提出了几种切实有效的保护策略，仿真结果证实了应用这些保护策略可确保vsc - hvdc中的一些重要部件能够在大多数类型的故障时免遭过电压或过电流的损害。
