高次衰減
英文
higher-order attenuation-
The research on attenuation features of intensity in the yunnan region by using intensity isoseismals of 127 earthquakes, and the following three conclusions have been put forward : ( 1 ) average ratio values of long - axis to short - axis of innermost isoseismal in the yunnan region is larger than eastern china and smaller than western china
摘要本文利用127次地震等震線資料，對雲南地區地震烈度衰減特徵進行了研究，其結果表明： （ 1 ）雲南地區地震烈度極震區等震線的長軸、短軸之比的均值，高於我國東部地區而略低於西部地區的平均值，烈度衰減方向性強。Secondly, better performance lifepo4 / c composite was synthesized by adding proper content of sucrose to the reactants, test results exhibited the initial discharge capability could get 130mah. g - 1 and the capability didn ’ t fade down after more than ten cycles ’ test
2 .添加適量的蔗糖制備出電化學性能良好的lifepo _ 4 / c復合的正極材料，其初始放電比容量高達130mah . g - 1 ;經10次充放電循環，材料的比容量幾乎不衰減。3 in renal failure stage, it can decrease hemolialysis times obviously. if you persist in treatment, it can enhance renal function restoration ability gradually and make you need no more dialysis therapy, prolong life, improve quality of life and make you reach recovery completely
腎衰期，可明顯減少血透析次數，只要堅持治療，逐漸提高腎功能恢復力，乃至毋需透析治療，延長生命，提高生命質量，最終可達到完全康復之效果。This continuous rule can put the suspension system in the optimal damping state. the skyhook principle can be combined in this control rule, which can further attenuate the vibration of the car - body in lower frequency range, but the acceleration response in higher frequency range tend to be larger
文中還研究了把基於天棚阻尼原理的阻尼控制策略結合到該控制系統中的復合控制方法，前者能使系統始終處于最優或次優阻尼，後者則能進一步衰減低頻振動，但也有增大高頻響應的趨勢。( c ) land natural productivity increase from 7843 kg / ( hm2 - a ) to 17335 kg / ( hm2 - a ) relate to altitude closely, and the mean rate of enhancing yield is 23. 53 percent in this region with annual enhancing - rate of 0. 64 percent in last 15 years. ( d ) there are many facters that have been influe ncing soil effective coefficient that ' s soil organic matter, total nitrogen, effective phosphine and soil texture in turn. in a word, attenuation cause of land productivity is the result of water and soil. ( e ) the forestland potential productivity change from 3986 kg / hm2 to 15034 kg / hm2, but it has a high distinction between southern aera and north area in yaan city. ( f ) the grassland potential productivity increase from 4085 kg / ( hm2 - a ) to 16973 kg / ( hm2 - a ), but it has a high classification of potential productivity, ( g ) ditribution map was formed of potential land productivity. ( h ) it could be act as decision support for agriculture development, national land planning and ecotop constructive, etc
5 、土地自然生產潛力水平的主要土壤限制因素為有機質、全氮，其次為速效磷和土壤質地；區域潛在生產力差異的制約因素，主要為土壤，次為水分，水、土兩項衰減合計為45 . 99 ，石棉、漢源兩縣水、土衰減達到60左右。 6 、林地潛力在3986 15034kg / hm ~ 2之間，高等級林地比重小，以大相嶺為界，北部的各縣林地生產力水平高，南部的兩縣林地生產力水平較低。 7 、天然草地生產潛力水平高，潛力在16973 4085kg / （ hm ~ 2 ? a ）之間，以高產的一、二、三級草地為主，且近10年來該比例變化不大。Secondly, methods of improving on probe are investigated in detail : using the electromagnetic shielding effect to decay the direct - coupled magnetic field and using the dual probe to control the energy flow, so as to make the probe to be shorter ; designing 3 - d pick - up coil array to increase detection sensitivity. at last, experiment system is set up to verify the simulation result and the comparing result shows simulation result agrees with experiment result
其次，對改進傳感器性能的幾種方法進行了詳細研究:利用電磁屏蔽效應以衰減在直接路徑上的磁場傳播、採用復式探頭激勵方式以實現能流控制，從而減小傳感器體積，模擬證實這兩種改進方案有效;設計三維周向檢測線圈陣列以提高缺陷檢測靈敏度，模擬結果證實三維探頭的周向靈敏性。分享友人
