Results showed that the CO2 absorb ability in the eight Crop systems net productivity process was 4 032 366ta^(-1); the amount of CO2 outlet in the soil was 3981753ta^(-1), less than the CO2 adsorb ability, so that the whole crop system was a weaker carbon sink process in the atmosphere. The continue planting species such as Rice, sugarcane, cassava, and melon crop or high haulm crops have the characteristics of annually crop net productivity CO2 absorb ability bigger than soil CO2 outlet and this systems had bigger carbon sink function ability; the short haulm crop systems of peanut, soybean, flowers, and vegetable annually crops net productivity CO2 absorb ability less than soil CO2 out let, but also carbon sink source. The CO2 absorb ability of fruits and economic parts above ground bigger than that which growth under ground. Except of the CO2 absorb ability less than the soil CO2 outlet in the peanut during growth in procreate period, the other seven crops CO2 absorb ability were bigger than that soil CO2 outlet during procreate period. Most of crops during growth in procreate period had carbon sink function ability, and only in barren period showed the carbon source function phenomenon.

结果表明：2005年广州市8种农作物系统作物净生产力吸收CO2 4032366ta^(-1)，其土壤CO2排放3981753ta^(-1)，吸收大于排放，对大气CO2而言，整个农作物系统是一个弱的碳汇；水稻、甘蔗、木薯和果用瓜4种连作或高杆作物系统每年作物净生产力吸收CO2量大于土壤CO2的排放量，系统具有较大的碳汇功能，花生、大豆、花卉和蔬菜4种矮杆作物系统每年作物净生产力吸收CO2量小于土壤CO2的排放量，系统起着碳源作用；果实或经济产量生长在地上部分的作物其单位面积吸收CO2能力比果实生长在地下的作物大；除花生在生育期间生物量吸收CO2量少于同期土壤排放以外，其余7种作物在生育期间生物量吸收CO2的量大于同期土壤排放，大多数农作物在生育期间具有碳汇功能，在撂荒期才体现碳源作用。

The carbon storage in different organs was positively related to the biomass of corresponding organs. Stem accumulated the highest carbon storage, comprised 52.20% of carbon storage in overstory trees, the rest in branch, leaf, bark and root, etc., seized 47.80%. The annual net productivity of 7-year-old A. crossicarpa plantation was 20.06 t/(hm^2a) and annual carbon fixation was up to 9.86t/(hm^2a).

厚荚相思各器官碳贮量与其生物量成正比例关系，树干的碳贮量最高，占乔木层碳贮量的52.20%，树枝、树叶、树皮和树根等碳贮量共占乔木层的47.80%。7年生厚荚相思人工林乔木层年净生产力为20.06t/(hm^2a)，碳素年净固定量为9.86t/(hm^2a)。

Soil labile organic matter and carbon management index are important parameter representing carbon cycle in soil ecosystem. Study on dynamics of them in the artificial Robinia in loess hilly area so as to understand the change and effect evaluation during process of ecological restoration is of great importance.

According to the morphological characteristics of cementite lamellae, the deformed pearlite can be divided into three kinds: irregularly bent lamella (pearlite lamella originally inclined with large angles to the rolling plane and irregularly bent after deformation); coarse lamellae with shear-band (the rhomboidal blocks of weakly deformed lamella bounded by shear band) and fine l...

按 渗碳体形态特点，变形珠光体组织可分为以下3种类型：(1)不规则弯曲片层型，即变形后的渗碳体与轧制面呈大角度偏离且不规则弯曲的珠光体。(2)带有剪切带的粗大片层型，即被渗碳体剪切带分开且变形轻微的珠光体。(3)精细片层型，即与轧制方向平行排列、片间距细小且渗碳体严重变形的珠光体。精细片层区域的比例随着轧制压下率的提高而增大。此外，重度冷轧变形还引起渗碳体严重塑性变形和部分溶解。
