The results show that with the increase of deformation strains and thinning of Fe-Cr fibers, the saturation magnetization are about 140 A·m2/kg constantly, and the remanent magnetism and coercivity increase gradually.The magnetic properties of Fe-Cr fibers are invariant when the Fe-Cr fibers were preserved in absolute alcohol or air for more than 1 a. After Fe-Cr fibers heated in air at temperature higher than 300 ℃ for 1 h, the Fe-Cr fibers transform from ferromagnetic α-solution to paramagnetic2O3, and the saturation magnetization of samples decreases remarkably. With the increase of deformation strains, the thermal stability of thinner Fe-Cr fibers decreases.

结果表明：随着变形量的增大和Fe-Cr纤维的细化，纤维的饱和磁矩基本恒定(约140 A·m2/kg)，而剩磁和矫顽力则逐渐增加； Fe-Cr纤维在无水乙醇和空气中储存一年以上，磁性基本保持不变； Fe-Cr纤维在空气中经300 ℃以上加热1 h后，逐渐由铁磁性的α-固溶体转变为顺磁性的2O3，饱和磁化强度显著下降；且随着变形量的增大，较细Fe-Cr纤维的热稳定性较差。

In support of the asteroid-impact model, it had been argued that the gradual cooling of the average ocean temperature would enable progressively smaller asteroid impacts (which are known to occur more frequently than larger impacts) to cool the Earth's climate sufficiently to induce ice-cap growth and reversals.

为了支持行星带影响模型，提出了这样的一个观点，这个逐渐的变凉，平均海洋温度变凉，这个逐渐的变凉会使得递进式地更小的行星带的影响（这个行星带被认为更加频繁地发生比起更大的影响）去降低地球的温度，降低地球的温度怎么样呢？充足到导致IC的增长和R。

The modern system of agriculture, which depends on the consumption of large quantities of fossil fuel, will be forced to change to a system where the interactions between organisms and environment and matter cycling are properly used for 3 reasons: 1 the depletion of readily available fossil fuel resources, 2 the level-off of the growth and yield response of crops with the increase in the use of fertilizer, agrochemicals and big machinery, and 3 the degradation of the environment along with the consumption of fossil fuel and its derived agrochemicals.

目前，现代化的农业生产系统建立在大量燃料的消耗上，虽然西方发达国家在近半个世纪的发展过程已经证明这是一种见效快、经济产值高的生产方式，但是随着在世界范围内可持续发展观念的日趋重视，这种生产方式的弊端也逐渐地受到人们的注意。1原有农业生产方式需要消耗大量的燃料资源；2虽然肥料、农药和大型机械的应用不断提高，但近几年农作物的生产和产量表现出停滞状态；3燃料及其副产品的不断使用导致环境逐渐退化。

The following results are found: Talbot self-imaging effect will appear when the full width at half-maximum of the incident short-pulsed light Δτ is within picoseconds and it will be gradually diminished at Δτ becomes small.

当激光脉冲的Δτ从皮秒逐渐减小时，塔尔博特自成像现象逐渐消失。而当激光脉冲的Δτ小于几十个飞秒时在第一个塔尔博特距离处光栅的衍射光强的最大值随Δτ的减小而减小。

The results showed that (1) COX-2 mRNA and protein existed in the mature male rat testis. COX-2 was localized in spermatocytes by immunohistochemistry.(2) COX-2 also existed in adult man testis. COX-2 protein was positively stained in spermatocytes and Leydig cells.(3) 2 weeks after administration of rofecoxib, the level of testosterone in the whole testis reached its lower values, being only 50% of control values. However, testosterone level recovered during 4 weeks. After such treatment, histologic examination of these testes showed atrophy of the seminiferous tubules and maturation arrest of spermatogenesis.(4) 2 weeks post-EDS, expression of COX-2 decreased significantly (P.005), in comparison with vehicle-treatment control. 4 weeks after treatment, a new generation of fetal like Leydig cells repopulated in the testicular interstitium resulting in COX-2 expression partially recovered. Although the expression of COX-2 mRNA and protein are enhanced at 8th week after using external testosterone, it wasn't significant higher than control group.

实验研究证明：(1)正常成年雄性大鼠睾丸组织中COX-2在mRNA和蛋白质水平均存在表达，免疫组织化学结果显示COX-2定位于曲细精管内的生精细胞；正常成年男性睾丸组织中同样存在COX-2表达，免疫组织化学结果显示COX-2定位于曲细精管内的生精细胞和Leydig细胞；(2)服用特异性COX-2酶抑制剂rofecoxib 2周后，实验组大鼠睾丸组织内睾酮的含量减少，为正常对照组的50％；持续用药4周后睾丸组织内睾酮浓度逐渐恢复至正常水平；COX-2酶活性降低后病理组织切片显示睾丸内曲细精管萎缩，生精紊乱，持续用药4周时影响最明显；(3)注射特异性Leydig细胞杀灭剂EDS 2周后，实验组大鼠睾丸组织内睾酮浓度降至极低水平时，COX-2的蛋白和基因表达水平也显著低于正常空白对照组（P.005）；使用EDS后第4周，睾丸组织中的睾酮浓度逐渐回升，同样组织中COX-2蛋白表达和mRNA表达水平也相应提高接近正常水平；使用EDS后4周开始给予外源性睾酮，6周和8周时COX-2表达水平的绝对值虽有提高，但与正常大鼠空白对照组比较并无显著性差异，说明外源性雄激素刺激睾丸合成COX-2的作用并不明显。
