Firstly, the 3D solid model of the analyzed object is built directly in the FEM software ANSYS 8.0 without using other CAD software. The influence of the side sizes of solid elements on computing results and the influence of coupling ways between different parts on the modal parameters are researched by simply modeling. And a new connecting method about joints in ANSYS is proposed and applied to finite element modeling of the test-bed for spindle system. Furthermore, several different computing techniques for modal parameters extraction are compared in solving the finite element model of spindle system test-bed. Many modal solutions are also done to achieve the relationships between the whole or part stiffness value and computed modal parameters. The laws about joint rigid parameters" influences on modal parameters are discussed by means of altering their values for conjoint parts. And by changing local rigid parameter values, the different location selections" influence on computed modal parameters is also studied.

Using CHIME geochronological method, the zircons and monazites from the Caoshan and Lishugou plutons are dated. The PbO-UO2* isochron age and weighted average age of the Lishugou pluton are all (173±10) Ma. For the Caoshan pluton, the zircon PbO-UO2* and monazite PbO-ThO2* isochron ages are (178±8) Ma and (177±3) Ma, and their weighted average ages are (175±6) and (177±3) Ma, respectively.

This paper analyzes the connotations of benefit salary, indicating that productivity depends on worker's salary, workers are motivated to be lazy, and worker's effort degree is a monotonic increasing function of its real salary. The Solow Model and the Shrinking Model are also adopted in the analysis. Then the currently adopted systems-the adjustment system of the total amount of wage and the classified encouragement systems for different positions-are discussed in the paper and their problems are pointed out as well.

nodular dermal vasculitis in lower extremities are often seen clinically in middle-age women, and are evoked by many causes. Some laboratory examinations have abnormal outcomes and we think these are related with autoimmune reactions of nodular dermal vasculitis. We can make diagnosis with clinical character of erythema and nodose lesions in lower extremities, laboratory examinations and histopathology inspection. Antibiotics, non- Steroid anti-inflammatory drugs, anti-tubercle drugs and corticosteroids are effective drugs.

According to the most unfavorable fire scenario for safety evaeuation, the AEST can be obtained through the spread of fire and smoke spread simulation. And the REST of different staff loads are calculated by empirical formula method. Through contrasting two times, whether evacuation passage setting can meet the evacuation requirements is confirmed, and then solutions are proposed. Then highway tunnel fire cause is discussed by Fault Tree Analysis method, and the effective measures to reduce the probability of tunnel fire are reducing the number of flammable materials and using fire-retardant or noncombustible materials for inner decoration are obtained.
