    光譜曲線的形狀只取決於物體的溫度,溫度低的物體光譜值在紅光,溫度越高,值越向長一端偏移,由黃光開始,到達藍光,再進入紫外線區域。
  6. Under confused sea condition, the structures may subject to very strong w ave impulsive 1oad due to slamming by the wave with significant crest when waves propagate underneath the structure and surge up to its subface. previous studies indicate that impact pressures are characterized by an initial peak pressure of considerable magnitude but of short duration occurs, followed by a slowly - varying uplift pressure of less magnitude but of considerable duration, and which typically is first positive, then decreases to zero and becomes negative, in hostile sea state, the peak pressures may cause the damage of the horizontal members of the structures or make the whole superstructure collapsed

    若這些海上建築物的上部結構底高程較低,在惡劣海況下當大浪在其面板下面通過並與之接觸時,面板下面除了作用有強度變化較緩慢的壓力外,在剛接觸到面板時尚存在著歷時很但強度極大的沖擊壓力,這種極強沖擊荷載會引起建築物的整個上部結構失穩或造成局部破壞。
  7. The use of wave packet to analyze the dynamics of quantum mechanical systems is an increasingly important method to the study of the classical - quantum correspondence. using the quantum gaussian wave packet analysis method, we calculate the autocorrelation function of the rectangular billiard, the peak positions of the autocorrelation function match well with the periods of the classical periodic orbits, which show that the period of the classical orbits can be produced by the time - dependent quantum wave packet method. we also discuss wave packet revivals and fractional revivals in the rectangular billiard, the results show that there are exact revival for all wave packet at each revival time. we find additional cases of exact revivals with short revival times for zero - momentum wave packets initially located at special symmetry point inside the billiard

  9. We researched the influences of systhesis temperature, heat preservation time, eu + concentration, reduction surrounding feeling and flux on luminescent properties of sral2o4 : eu2 + phosphors, optimized the experiment conditions and reduced systhesis temperature about 100 c. we found that the systhesized sample ' s luminescent brightness is better with increasing systhesis temperature, but the phase component is more complex. we found that the luminescence brightness of sample appear a increasing process at first, and then a reducing one with the raise of eu2 + concentration, it indicated that the luminescence brightness is not better if the eu2 + concentration is too high or low. we found that the systhesized sample can not bright at too long heat preservation time, and the luminescence brightness is lower at too short heat preservation time. we found that particle diameter is bigger, the wavelength of emission peak is longer

    研究發現合成溫度高,合成樣品的發光效果好,但物相組成也較復雜; eu ~ ( 2 + )離子在一定摻雜濃度范圍內,合成樣品的發光亮度先是出現一個提高過程,然後是一個降低過程,說明eu ~ ( 2 + )離子濃度高或低都不利於合成樣品發光;保溫時間較長,合成樣品不發光,保溫時間較,合成樣品發光效果不好,只有合適的保溫時間才能合成發光效果好的樣品;合成樣品的粒徑大小與發射的位置具有一定的關系,粒徑越大,發射越偏向長方向;助熔劑對樣品的合成溫度和發光性能都有影響,助熔劑的量較低時,主要表現為助熔作用,對發光影響不大,助熔劑的量較高時,使得樣品發光亮度降低和余輝時間縮;還原方式的不同,合成樣品的發光性能也不一樣。
