In the beginning, at the situation of high blood volume, if the blood glucose sufficient, the erythrocytic function of making ATP by glucose is normal, the free radical and the anti-free radical of the rat basicly keep balanced, erythrocytic deforming ability is not influenced greatly; while the erythrocytic function of making ATP degenerates in sport iron deficient erythrocyte formation and hemolysis, especially the former; and the vitalities of anti-free radical reduce greatly in blood, liver and Erythrocyte, the reducement of liver SOD vitality in the former and erythrocyte SOD vitality in the latter are more obvious, and the total blood SOD amounts reduce identically; The erythrocytic deforming ability reduces greatly too, but there is no obvious difference between the two groups, but the tendency of the inner-mechanism may be different needing to researching deeply later.

而长期递增的大负荷运动造成缺铁性红细胞生成或溶血发生时，红细胞利用葡萄糖制造ATP的功能下降，且前者下降更为明显；抗氧自由基活性均显著降低，HA组肝脏SOD活力和IDA组红细胞SOD活力降低更为明显，而二者血液总SOD降低一致；红细胞变形能力均显著下降，但内在机制的倾向性可能有所不同，建议进一步深入研究机理。

Noise can be reduced by about 2 dB by using oil-resistant rubber isolator to reduce solid-borne sound transmission; the setting-up of semienclosed noise barriers can not only reduce the work region's noise of workshop by 13 dB, but also adapt to the gas's characteristic involved with H2S, CO, and other poisonous components without supplied mandatory ventilation; locating the noise absorbers on the walls and ceiling of workshop can reduce noise by 8 dB; the exhaust silencer's elimination volume can reach above 30 dB which is designed in accordance with the exhaust noise spectrum characteristic of gas-combustion generator. By the combination of these measures, the noise of the gas- combustion generator will be under effective control, so that the gas power plant's noise pollution problems can be resolved.
