For modern communication chamber, it ' s very important for management to get the condition of these chambers and prevent fire. now supervising modern communication rooms " condition is developed towards multi - way integration, combination of supervising - diagnostic - maintenance determination and network, and then condition supervision has typical character of information fusion. the quality of information could be improved by making full use of multi - datasourse inter complementarily and redundance. the problem such as much quantity, extensive distribution, supervisement, diagnostic and management and so on could be settled through network, at the same time the remoted condition supervising system based on multi - sensor multi - layer information fusion could be realized conveniently

The total ozone distribution over stratosphere layer in china appears obviously seasonal variation tendency, that is, the value of total ozone in spring and winter is higher than that in summer and autumn, while the maximum of surface o3 over waliguan is in summer, which is relatively late, approximately 2 - 3 months, it illustrates that the vertical transport from stratosphere has important effect to the increasing of surface o3. compare to the izana global observatory, surface o3 has been slowly increasing, but not so stable, it also shows that the monitoring of surface o3 has global scale, and its data has comparability in the world
( 7 )中國大陸上空平流層臭氧柱總量分佈存在明顯的季節變化趨勢,即冬春季臭氧柱總量高於夏秋季;瓦里關近地面層臭氧濃度最高值出現在夏季,落後平流層2 3個月,說明在瓦里關地區夏季平流層o _ 3的垂直輸送對地面臭氧濃度的增加發揮著重要作用; ( 9 )與izana全球站相比,地面o _ 3均呈逐年上升趨勢,上升較為緩慢,且不太穩定,說明瓦里關地區地面o _ 3監
測具有一定的全球尺度和國際可比性。
At present, h9n2 subtype influenza viruses are prevalent in terrestrial poultry worldwide. what is more, the introduction of these new types of terrestrial poultry was in southern china, a hypothetical epicenter for the emergence of pandemic influenza viruses. it is, therefore, more important to carry out influenza surveillance, especially in those newly forming poultry in this region
目前h9n2亞型流感病毒分佈廣泛,多次發生傳染人的事件,加上華南地區作為理論中「流感中心」的特殊地位,因此對該地區進行嚴密的流感病毒監
測具有重要的意義,特別是對近年來該地區不斷涌現的新種群中流感病毒進行檢
測。
Therefore, leakage current measurement on flashover process during the insulators icing has both important academic meaning and engineering value
因此,對覆冰閃絡過程中泄漏電流的檢
測具有非常重要的工程應用價值和學術意義。
The comprehensive research of typical wells in water - yield pattern shows that the theoretical curves are accordant with actual situation, indicating this method is applicable to analysis and prediction of water - yielding pattern in such a reservoir
對典型井的產水規律綜合研究表明,理論曲線與油藏實際產水情況比較吻合,說明該方法對薄層底水油藏產水規律分析預
測具有較好的適用性。
These results demonstrate that the dot - immunogold assay shows its practical value to monitor the brucella infections among the epidemic area and individuals with different occupations in the un - epdemic area, and this method can also be applied for the clinical investigation and epidemiological survey of brucellosis

The measurement of deflection of a bridge is crucial constituent part in the monitoring of bridges. the majority of existing methods about bridge deflection measurement can not accomplish the real - time and long - range measurement. the ultrasonic method based on connected pipes still has shortage in precision and speed of measurement. to satify the need of deflection measurement of the dafosi bridge of changjiang river, an opto - electronic measurement method is to be used to improve on the method based on connected pipes. furthermore, we will design an automatic opto - electronic deflection measurement system based on connected pipes which can be practised in the long - span bridge
大型橋梁的安全監測具有重要的現實意義,而撓度監測是橋梁監測的一個重要的組成部分。目前現有的許多撓度測量方法還不能實現實時遠程監測,已有的連通管式超聲波法還存在著精度較低,測速慢等不足。針對大佛寺長江大橋撓度測量的需要,在此採用精度較高的光電測量方法結合連通管的優點加以改進。
