The biomass of each specie was calculated according to the materials of tally, such as height, diameter and so on in the forest inventory data.
Materials and methods Summary of the study area.
First, the main tree specie’s biomass model in the study area was collected and established, and all tree species’ biomass per area was calculated based on the tally materials of the forest resource inventory; then subcompartment biomass was calculated based on the tree specie composition and the subcompartment area of the subcompartment investigation materials.

Preparation of Nanoscale CuO Powders ZHAO Xihua a , XU Min b Key Laboratory of Bio-based Material Science and Technology of Ministry of Education, Northeast Forestry University, Harbin 150040, P.R.China a 1984zhaoxihua@163.com, b xumin1963@126.com Keywords: nano-CuO; direct precipitation method; copper yield; particle size Abstract: Cu(OH)2 precursor was synthesized by direct precipitation method and CuSO4 and NaOH were used as raw materials.
These results showed that the development of nano-particles is normal and the preparation conditions is reasonable, but there is a "soft reunion" phenomenon, which is an inherent feature of nano-powder materials, the smaller the particle size is, the more serious reunion is.

Ceramic materials are widely used in the fields of aviation, chemical industry, military, machinery, electronics, so there are so many researches on ceramic materials.
As we know, nano-indentation test is an effective mean to study materials.
In order to use ceramic materials, it is significant to make further study on ceramic materials.
From the nano-indentation test of ceramic material, we can obtain more properties and make full use of ceramic materials.
