Analyze the basic actuality from three aspects, including the fleet makeup and system of management, situation of development and competition, ports' actuality and its influence to shipping enterprises.
The freight volume of railway container transportation was 2.7 million TEU in 2005, which only was 2.7% of the total volume of rail cargo, 1. 64% of total cargo throughput in Chinese ports.
The power gain of a continuous wave at 5.4GHz is 14.2dB,with an output power of 4.1W,while the corresponding results of pulsed power test are 14.4dB and 5.2W. Two ports impedance characteristics demonstrate good potential in microwave applications.
The display of signal curve is composed of an AT89S52, a TLC2543 and a 128×64 pixels graphics LCD module. The ports from P2.4 to P2.7 of AT89S52 are linked to the ports of CS, DOUT, DIN, and CLK, respectively.
A principle of designing realizable precision interfaces between sensors and digital ports of microcontrollers and microconverters which enable one not only to measure a physical variable but also to estimate its derivative was proposed.
The sensor is inserted in a vacuum chamber; the rotating mechanism of the sensor and location of the ports in the facility enables measurements along the plasma column.
It is proposed that the compact neutron cameras be placed inside the shielding blocks located in the equatorial (nine collimators) and diverter diagnostic (seven collimators) ITER ports.
The majority of seamen in China can predict the time of tide at the ports of their navigational activities by means of the method of using the daily log of 0.8 hour from new moon or full moon instead of the moon's transit which is added to the luni-tidal intervals.The equations used in the method are as follows:1.Time of high water=(No.of lunar date-1)×0.8 hour+high water interval.2.Time of low water=(No.of lunar date-1)×0.8 hour+low water interval.3.Time of high weter=time of low water±06124.Time of ...
The relations among the various elements of a conductance matrix may be expressed in certain fotms of inequalities, These inequalities are different for conductance matrices corresponding to different trees of the ports. In this paper these inequalities are fullydiscussed, and several important theorems concerning them are derived. When the tree ofthe ports corresponding to a given condu6tance matrix of order n is determined from itssign matrix, the application of these theorems will yield the c...
The distribution and arrangement of the segmental bronchi and blood vessels of the lower lobe of right lung have been studied in fifty adult cadavers,by the same methods as those for the right upper and middle lobes reported previously. 1.Five segmental bronchi are constantly present in right lower lobe as described in textbook.Subapical bronchus (B~*) has been identified only 46% in this series of specimens. The prevailing pattern of the branches of the apical bronchus is a bifurcation of B~6c,B~6a+b. In 1...
