春风吹呀吹呀，吹醒了正在冬眠的小青蛙；吹绿了大地上的一草一木；吹红了在争奇斗艳的花儿；吹来了那活泼可爱的小燕子。。。。。我走进那奇特的大自然，倾听春姑娘的脚步，感受春的气息，探索春的奥秘。。。。

There are experimental results as follows:(1) Eriophorum comosum Nees shows strong cold resistance in plasmalemma permeability research. The lethal temperature of Eriophorum comosum Nees is the lowest LT_(50 in comparison with another two plants and is lower than -11.5℃ in August 2005 and December 2005; Soluble protein content of each plant is rising before or after cold hardiness. By SDS-PAGE, Protein band is analysed. Band quantity of Eriophorum comosum Nees is the most and its band color is darkest.(2) Soluble sugar content of three plants after cold hardiness are higher than before cold hardiness, moreover soluble sugar content after cold hardiness shows a decline and there is a narrow range in Eriophorum comosum Nees; Free Proline accumulation is changed by cold stress, and cold resistance is relative to free Proline accumulation; chlorophyll content of both three plants, including chlorophyll a, chlorophyll b and chlorophyll a/b, show a decline tendency along with the descent of temperature. Cynodon dactylon is highly sensitive to cold stress.(3) The soil POD and urease activities' absolute value of Erioophorum comosum Nees and Pogonatherum panideumHack were more than that of Cynodon dactylon before or after low temperature stress, especially POD activities.

实验结果表明：(1)在膜透性的研究中，丛毛羊胡子草抗寒性最强，采用电导率法测得半致死温度LT_(50最低，丛毛羊胡子草抗寒锻炼前后半致死温度LT_(50均小于-11.5℃；在可溶性蛋白含量研究中，抗寒锻炼前后三种植物的可溶性蛋白含量均增加，同时采用SDS-PAGE法，通过对蛋白条带分析，以丛毛羊胡子草条带数最多且着色深；(2)在可溶性糖的研究中，三种植物经抗寒锻炼后叶片可溶性糖含量都比抗寒锻炼前高，且经过抗寒锻炼后三种植物可溶性糖均呈下降趋势，丛毛羊胡子草可溶性糖含量下降较小；从游离脯氨酸含量可知，低温的胁迫影响了植物叶片游离脯氨酸的含量变化，植物的抗寒性与游离脯氨酸有关；低温胁迫下三种植物叶绿素含量随着温度的下降，叶绿素含量、叶绿素a、叶绿素b和叶绿素a／b均呈下降趋势，狗牙根对低温胁迫最为敏感；(3)低温锻炼前后，丛毛羊胡子草和金发草的土壤过氧化物酶与脲酶活性的绝对值均大于狗牙根的，特别是过氧化物酶，说明丛毛羊胡子草和金发草的酶活性大于狗牙根的。

This invention relates to a method and device for generating cold atomic beam. Said method includes heating hot atom source in vacuum chamber to form atomic saturated vapor pressure atmosphere, cooling hot atom by three-D MOT to below 200uk and trapped to form cold atomic cloud, by the quarter wave plate reflection mirror in MOT the laser radiation pressure being unbalanced to make cold atom emitting along said direction, four tape arranged straight line set with contrary current direction is set in atom beam emission direction, which makes the atom emitted to forward to obtain cold atom beam with low speed, large flux and small transverse speed, laser beam vertical with atom beam set in the direction of cold atom emitting for atom beam state preparation to realize state concordant emitted cold atom beam.

本发明涉及一种冷原子束产生方法和装置，该方法包括在抽真空的真空室内，加热热原子源，在真空室中形成相应的原子饱和蒸汽压气氛；采用三维MOT对热原子进行冷却，冷却到200μk以下，并被捕获形成冷原子云团；通过三维MOT中开小孔的四分之一波片反射镜，而使得在该方向上激光辐射压力不平衡，使冷原子沿此方向出射；在冷原子束出射方向上，还置有载有彼此电流方向相反的四根成锥形排列的直导线，从而原子出射时将在磁场的作用下，不会沿横向膨胀而向前射出；便得到了出射速度低的、通量较大的、横向速度非常小的连续冷原子束；同时在冷原子束的出射方向上，设置有与原子束垂直的激光束，用于原子束的态制备，实现态一致的出射冷原子束。
