Indirect carbon emission is the carbon footprint condensed in materials consumed in maintenance of fertilization, pest control, shading and supporting.
Because of great time span of this stage, the indirect carbon emission of assistant materials should be included in the total carbon footprint of this stage.

This method considered that the material expands when heated, and if the sleeve and the bearing bush temperature increases by 1 ºC, the corresponding stress would be transferred to the connecting rod shank. 22500 N preload was brought to bear on each bolt.

Introduction Lake sediment is an important library of organic carbon, nitrogen, phosphorus and other nutrients, gradually accumulated of nutrient from the basin flowing into the lake[1].It has a great significance on the system of organic carbon, nitrogen and phosphorus cycle and the ecological system of material circulation in the whole lake[2].
There were significantly positive correlation between them.Thus, the concentration trend of TP,TOC and TN has a highly consistent, their depositional environment and source material behavior are similar and homology.
