Initially the following measures are taken for association of the angle positions to physical reflectors, and for determination of the position of the vehicle (10): i at least three angle values with a suitable distribution over the search sector is selected, ii the angle values are associated to reflectors and a position is determined for the vehicle on the basis of the known position of the assumed reflectors, iii if the vehicle position determined in this way is within a certain part of the transport area the other angle values are associated to reflectors, iv for each angle value, existing deviation is determined between detected angle values and angle values expected between the vehicle position and known reflectors, v the measures taken are repeated for each possible combination of selected angle values.

最初使用下列步骤使这些角位与反射器关联以便确定车辆（10）的位置：i）在该搜索扇形上选择至少三个合适分布的角度值，ii）使各角度值与各反射器关联，根据假设反射器的已知位置确定车辆的位置，iii）如果如此确定的车辆位置在该运输区的某一部分中，则使其他角度值与反射器关联，iv）对于每一角度值，确定所检测角度值与车辆位置与己知反射器之间预期角度值之间的偏差，v）对于所选择的角度值的每一种可能组合反复进行这些步骤。

Citri had been selected by ribosome display in previous research. In order to express the scFvs with bio-activity efficiently, the genes of the selected scFvs were transformed into Escherichia coli HB2151 for expressing resoluble antibodies. The expression levels of scFvs were detected by dot blotting and Western blotting, and the expressed scFvs were purified by affinity chromatography, and then the activity of the purified scFvs was tested by enzyme-linked immunosorbent assay .

So it needs improving or alternating urgently. Some good germplasms for rootstocks for citrus have been picked out and introdcted into. Some somatic hybrids used as rootstocks have been selected through somatoplasm fusion. Some methods in early identification on stability of inherence and copatiblity and dwarf are explored, and they need improving. Rootstocks having some virtues have been selected, but they cannot take the leading place of trifoliate orange. The research method that the rootstocks are only compared with each other should be altered into that the rootstocks and given control measures or environmental conductions are connected to make the rootstocks compared with each other.
