婉轉的針對這個問題回答，汽缸壓力的峰值不能超過引擎機械零件本身的限制或汽油爆震的極限，以上兩個狀況何者先出現，就是極限的發生時機Considering that the characteristics of our country ' s highway tunnels are always of long spans, tabular and of various geometry, by means of thorough analysis of the different problems existed in the design of support structures of the tunnels at present, this paper pays special attention to the two key problems, optimization method of form selection of structural section of the tunnel as well as the stability and bearing capacity of the support structures, in the design of the long and large tunnel on high - class highway, introduces the simplified complex - form optimum method in the structure optimization theory, discusses the optimum design model of lining section of highway tunnel with satisfying demands in building clearance, ventilation and load conditions, puts forward an optimization method of form selection of three different kinds of lining sectional forms ( i. e. single - center circle, three - center tabular circle and three - center sharp circle ), establishes a complete set of systematic optimum design the ory and method of long and large tunnel on high - class highway, develops the corresponding computer software used on the planned xuefeng mountain highway tunnel on shaoyang to huaihua expressway in hunan province for optimization of form selections of the structural sections, and obtains a series of relatively reasonable structural design parameters
本文針對我國公路隧道多為大跨度、扁平、幾何形狀呈多樣化的特點，通過深入分析目前隧道支護結構設計中存在的各種問題，抓住高等級公路長大隧道設計中隧道結構斷面的優化選型及隧道支護結構的穩定性與承載能力兩個核心問題，引入結構優化理論中的簡易復合形優化方法，深入探討了滿足建築限界、通風條件、受力狀態約束等條件下公路隧道襯砌斷面優化設計模型，提出了三種襯砌斷面形狀（單心圓、坦三心圓和尖三心圓）的優化選型方法，建立起一套完善的高等級公路長大隧道的系統優化設計理論與方法，並開發出相應的計算機程序，用於擬建的上海至瑞麗國道主幹線湖南省邵陽至懷化高速公路雪峰山長大高速公路隧道的結構斷面優化選型，得出了一系列較為合理的支護結構設計參數。Against the status of large scale ultra low frequency air spring vibration isolation platform, which is low damping and poor performance of low frequency, and after analyzing the existing key damping system, a new type differential electromagnetic damping system ( emds ) is developed in this article in order to reduce the resonance peak of the platform effectively and improve the low frequency performance of the platform
本文針對大型超低頻空氣彈簧隔振平臺阻尼小、低頻隔振性能較差的現狀，在比較多種提供阻尼力的方法后，提出了用電磁力作為隔振平臺的阻尼力，並開發研製了差動式電磁阻尼器系統。該系統可以有效降低隔振平臺的諧振峰值，從而達到了提高隔振平臺低頻性能的目的。Our group has prepared nanometer - scale metal films in layer structures on glassy carbon ( gc ) substrate by cyclic voltammetric deposition. by using co as probe molecule, we have revealed for the first time, abnormal ir effects ( aires ) on these layer nanostructured films. the alres consists of several abnormal ir features including the enhancement of ir absorption, the inversion of ir band direction ( anti - absorption ), and the increase of fwhm ( increase of the number of different adsorption sites )
本研究小組採用電化學循環伏安電沉積法在gc基底上制備層狀納米結構金屬薄膜，以co作為分子探針，觀察到異常紅外效應（ aires ）光譜特徵，即co等探針分子發生紅外吸收增強、紅外譜峰方向倒反（反吸收）和譜峰變寬（振動能級離散程度增加） 。The classification and characterization of the laser crystals were introduced in the thesis, and the research and development of the yvo4 crystal were systematically reviewed. the detailed experimental project was carried out to probe the reason of the absorption peak in the 1552nm of yvo4 crystal. the raw materials of yvo4 were synthesized through several different procedures
本文簡要的介紹了激光晶體的分類及其性能，對釩酸釔晶體的現狀和發展進行了總結，並針對本課題的目的設計了詳盡的實驗方案以探究部分釩酸釔晶體在1552nm處存在吸收峰的原因。Through analyzing the present operation condition and heat supply respect of the beihai heat power plant which is the largest heat and electricity cogeneration and concentrated heat supply corporation in dalian, a scheme is settled to install a climax load adjustment boiler in the plant
