The Value of Ci of leaf in Rain cultivation is less than in Open-air cultivation.The content of chlorophyl a and b of Rosario Bianco leaf in Rain cultivation is higher than in Open-air cultivation and the chlorophyl content of the 5th leaf is maximal in Rain cultivation. Stem diameter of Rosario Bianco were increased 8.68%~10.74% during the stage of rain growth in Rain cultivation. The study shows the leaf area of Rosario Bianco in greenhouse is lager than unsheltered and the environment of greenhouse is suit for grape leaf growing.

The results show that the air crossing pressure pulse magnitude of the container generated in the tunnel is 3.46 times that generated in open air when container flat wagon at the speed of 160 km/h passed by EMU moving at the same speed. Both the lateral force and overturning moment of the container train during the crossing induced in open air and tunnel are approximately proportional to the square of running speed of the passing train. The pressure of crossing side and uncrossing side for the container flat wagon is almost equal since the one-dimensional characteristic of pressure distributing induced in the tunnel is not faintish. Consequently, the value of the lateral force and overturning moment of the container train generated in open air is greater than that generated in the tunnel, about 1.1 times.

At last the paper realized the advantages and disadvantages of passive solar building and adnvanced some suggestions in future research. From another point, the paper logged the process of the building of the experimental equipment and the mounting of the measurement equipments that accumulated some operating experimence.Carrying experiments, calculating and analyzing the experimental data for more than 2 years, the paper gained some constructive conclusions. In winter the indoor air temperature and RH are lower than comfort criteria, but people feels very comfortable in the passive solar house. The thermo-circulation formed by Trombe wall play an important role in improving indoor air temperature and RH. Based on the analogy analysis theory, the natural convection heat transfer in the air gap can be treated as superposition of two natural convection heat transfer processes occurring over isolated isothermal vertical flat plate, in this case namely the massive wall and glazing. Two empirical formulas for Q and Nu are obtained. The investigation shows that the optimal time to open the damper should comply with the period that the thermo-circulation happens which can be controlled by thermal response characteristics of Trombe wall surface temperature and air temperature in the air gap.
