Biomass raw material leads to overall losses in 2012 because of the high cost increasing fast.
Upstream enterprises equipment and raw material can provide new energy power generation.
Biomass power generation still has the raw material supplement difficulties is still the obstacle of biomass power generation development.
Production dispersion, inconvenient transportation, and high cost are all the problem of the raw material.

Introduction Carbon/carbon (C/C) composites are attractive materials for a wide range of applications due to their excellent high temperature properties, such as low thermal expansion coefficient, high thermal stability, and high retention of mechanical properties at high temperatures [1].
Model Development In this work, MTS as precursor material, hydrogen and argon as carrier gas and diluting gas are pumped into CVD reactor, and SiC was deposited on C/C composites.

Typical S-N life curve [2] is usually formulated as Nf i Sim = C (2) where m and C are material (structural) dependent parameters determined by experiments.
Variable Filtering Threshold according to Equal Damage Principle As well known, most structural materials have their "fatigue limits" [2] below which the small load cycle would not cause any fatigue damage.

Introduction As technology progresses,in the fields of aviation, spaceflight, military and civil purpose, aspherics devices have played a very important part in the essential equipments ，such as the pick-up head that equiped by the reconnaissance satellite ， the telemicroscope that employed by celestial observation, the optical reflector and the microscope that used by medical sciences, etc, they all have the needs of using high-accuracy aspherics device [1].The adoption of aspherics device in optical system have the advantage of improving picture element, simplifying the system, reducing dimension and weight of system.Yet,the utilization of aspherics device is retarded for its much more difficult manufacture than the sphere device's.
The resection rate of material means the resectable material in unit time, is represented by Zw （mm 3/s）.
Zw and Zs are related with material itself, action velocity, the grinding force between the grinding wheel and the piece's contact area and temperature, etc. and change with the normal grinding force proportionally probably.
