A concrete ideas are described in the areas as follows; reform of the management and administration system, readjustment of passenger train structure, improvement of passenger train speed, rational arrangement of passenger stations, construction of fundamental installation for passenger traffic, applications of scientific and technical means and modernization equipment, and cultivation of staff and workers.

In China, large proportion of motorcycle engine displacement is narrow in the range of Small-medium displacement(50ml～250ml), and much of motorcycle engine valve train structure is Single Over Head Cam (SOHC) structure.

Unlike the wind action, in the presence of flows of density in the upper layer in the region of the strip, the initial period of generation is characterized by the formation of intense perturbations without train structure.

Spike train structure following application of nociceptive potassium chloride solutions to the cat saphenous nerve

This paper examines the amplitudes, frequencies and wave train structure of tsunami waves recorded by tide gauges located more than 20,000?km from the source area along the Pacific and Atlantic coasts of North America.

microcephala discriminate against calls that overlap so that the call pulse-train structure is degraded.

The mechanism for this feature of the "transition stage" is the existence of the "long-train structure" in the parameter space.

The detailed analysis of the dynamical process of coin tossing is made. Through calculations, it is illustrated how and why the result is extremely sensitive to the initial conditions. It is also shown that, as the initial height of the mass center of the coin increases, the final configuration, i. e. "head" or "tail", becomes more and more sensitive to the initial parameters (the initial velocity angular velocity, and the initial orientation), the coefficient of the air drag, and the energy absorption factor...

The detailed analysis of the dynamical process of coin tossing is made. Through calculations, it is illustrated how and why the result is extremely sensitive to the initial conditions. It is also shown that, as the initial height of the mass center of the coin increases, the final configuration, i. e. "head" or "tail", becomes more and more sensitive to the initial parameters (the initial velocity angular velocity, and the initial orientation), the coefficient of the air drag, and the energy absorption factor of the surface on which the coin bounces. If we keep the "head" upward initially but allow a small range for the change of some other initial parameters, the frequency that the final configuration is "head" would be 1 if the initial height h of the mass center is sufficiently small, and would be close to 1/2 if h is sufficiently large. An interesting question is how this frequency changes continuously from 1 to 1/2 as h increases. Detailed calculations show that such a "-transition" is very similar to the transition from laminar to turbulent flows. A basic difference between the "transition stage" and the "completely random stage" is indicated: In the "completely random stage", the deterministic process o?the individual case is extremely sensitive to the initial conditions and the dynamical parameters,but the statistical properties of the ensemble are insensitive to the small changes of the initial conditions and the dynamical parameters. On the .contrary, in the "transition stage", both the deterministic propess of the individual case and the statistical properties of the ensemble are sensitive to the initial conditions and the dynamical parameters. The mechanism for this feature of the "transition stage" is the existence of the "long-train structure" in the parameter space. The implications of this, analysis on some other random phenomena are discussed.

In order to suit the newtraffic situation and the need of task, the Ministry of Railways organized the drawing of new train diagram by railway administrations and sub-administrations, which will be carried out from April 1, 1993. Compared with the current train diagram, the new one has its characteristics and changes, which are: increasing train pairs, weight and speed, and enlarging traffic capacity; strengthening passenger and freight traffic organizatin and locomotive running operation; adjusting train structure and optimizing train running program; developing fast freight transport, direct container transport and heavy haul transport; raising safety coefficient of operation, and raising quality of the drawing of train diagram. At the same time, the paper points out that widespread publication and mobilization must be done, and major efforts should be de-voted to strengthening transportation organization and applying the new 1993 train diagram.
