Material and method Plant Material C Wild C. lavandulifolium seeds were sown in a 150mm pots with vermiculite.
This method was chosen due to the small quantities of material available for analysis and the low levels of expression of LFY in other species[6,27].

Fig. 1 Fracture site of pitman shaft Fig. 2 Macrofractograph appearance The material type, fractographic appearance, microstructure and hardness of the steering gear pitman shaft were analyzed in the paper, and causation and mechanism for fracture were detected and determined.
These working procedures were as follows: cutting material → stamp forging →normalizing → machining → carburizing → quenching and tempering → treated with shot penning →refined grinding.
Increasing cutting allowance on the non-carburizing parts is easy and possible, although waste metal materials.

The revolutionary design of diamond dresser is based on the pattern forming of a strong polycrystalline diamond material that is sintered at ultrahigh pressure (about 6 Gpa) and high temperature (about 1350 0C).
The groove, however, is shallower than the dressing depth because the pad material springs back due to elastic deformation [7].

Applications and geological problems that can be solved: (1)Direct search for radioactive mineral-rich geological body, such as uranium, thorium ore deposits. (2)Indirect detection of fracture structure, fracture structure belt often have strong natural α, γ-strength. (3)Radiation detection of building materials, interior decoration materials. 2.4 Gravity measurement Including measuring Δg, gradient measurement, torque measurement. geophysical conditions of application: require obvious difference density during the stratigraphic, geological and rock.

Performance of Treatment of Domestic Wastewater by Sequencing Batch Biofilm Reactor Dong Yuan1, a 1 Depa China rtment of Civil Engineering, Luoyang Institute of Science and Technology, Luoyang 471023, ayuandong22@126.com Keywords: SBBR; biofilm; domestic wastewater Abstract The objective of this work was to evaluate the performances of A lab-scale innovative sequencing batch biofilm reactor (SBBR) to treat domestic wastewater，in which a acryl cylinder (height 200 mm, diameter 70 mm) was equipped and many fiber threads were attached to the surface of the cylinder as the bacteria carrier.
The SBBR system developed in this study is different from the conventional one, i.e., the specific surface area is larger; oxygen partially penetrates the biofilm, generating an oxygen concentration gradient. 1 Materials and Methods 1.1 Materials Domestic wastewater was used in this study, which was taken from the wastewater well in China University of Geosciences (Beijing).
