这个系统可以展示从较高激发态到基态的无粒子数反转激光增益，也可以用来实现粒子数反转激光，同时这个系统还可以产生无吸收的较大折射率。

The preparation method comprises monomer synthesis and polymer synthesis. The polymer synthesis is that cyclopentadienyl sodium monomer is added into metallic cobalt complex-triphenyl phosphorus cobalt chloride under strict oxygen-free and water-free conditions, and then double inner alkyne or outer alkyne conjugate monomer is added in, and after reaction, the precipitation, filtering, abstersion and vacuum-drying are carried out, the large molecules polymer containing cyclopentadienyl cobaltocenium organometallic cobalt is obtained.

制备方法，包括单体合成和聚合物的合成，聚合物的合成是在严格无氧无水条件下，在金属钴配合物三-三苯基磷氯化钴，加入环戊二烯钠单体，随后加入双内炔或双外炔共轭单体，反应后沉淀，过滤，洗涤，真空干燥，得到含环戊二烯茂钴有机金属钴的大分子聚合物。

HLG of the 2nd grade acquired higher accuracy than LLG, and no significant difference was found either between HLG and MLG or between MLG and LLG; HLG of the 3rd grade had higher accuragy than both MLG and LLG, and no significant difference existed between MLG and LLG.

In order to understand the degree of simulation produced by exercise loads subjected to li zhu-hong during sub highland training to his body, and to grasp sub highland training patterns, the authors tracked and tested conventional uric indexes and some biochemical indexes of li zhu-hong at different training load stages during sub highland training, and revealed the following findings: different exercise loads and intensities have no significant effect on the number of red blood cells; training with high exercise intensities can increase the levels of serum urea nitrogen and creatine kinase, and significantly increase the percentages of testosterone and cortisol, which recovered their normal levels after exercising; there is no significant change in specific gravity of urine, acetone body, nitrite and white blood cells before and after exercise loads; the levels of urine protein, occult blood, bilirubin and urine bladder essence increase after exercising.

马拉松运动员李柱宏为了备战北京奥运会，在海拔1 750 m的兰州愉中亚高原进行了为期4周的针对性训练，为了解李柱宏在亚高原训练中运动负荷对机体的刺激程度，掌握亚高原运动训练的规律，对李柱宏在亚高原不同训练负荷阶段尿常规指标和部分生化指标进行了跟踪检测，结果发现：不同运动负荷和强度对红细胞数无显著影响，大运动量训练可使血清尿素氮和肌酸激酶水平升高，睾酮和皮质醇比例明显升高，运动后恢复正常；运动负荷前后尿比重、酮体、亚硝酸盐及白细胞无显著变化；运动后尿蛋白、隐血、胆红素、尿胆元水平上升。
