Dividing track of athletics games usually uses the oblique line passing method by using draw lots to determine track orders,it is traditional method and has the certain sufficiency.

Carry on lead transfer through the diagonal line method, not only solved basically impersonal condition limit of the traditional triangle connection survey the method request, but also enhanced the engineering lead accuracy and measure the work efficiency.

The temperature variations were deduced by the four one-ionized Ca spectral lines and the Boltzmann plot,and the relationship between the plasma temperature and the concentration was obtained too.

And the negotiation calculation is made.

The geometrical negotiation and dynamic negotiation analyses are made.

When the negotiation calculation is made for the D45 well car, it is necessary to consider the side displacement effect of the carbody center plate support caused by the guiding device.

Study on dynamic performance of the Low-speed EMS maglev car in curve negotiation;

In the light of the maglev vehicle with 5 units bogie,the kinematics principle of magiev vehicles during curve negotiation is investigated.

In this paper, aimed at the problem of curve negotiation in railway, high-speed vehicle-track dynamical model is built.
