An important issue in research of watermarking is the compromising between imperceptibility and robustness [1].
With Eq.1 toEq.4 can be critical of the visual threshold of wavelet coefficients:

An aqueous solution of citric acid was mixed with the metal nitrates solution, the molar ratio betweeen total metal ions and citric acid was controlled at 1:1, 1:2, and 1:3.
Results and discussion Fig. 1 shows the XRD pattern of cobalt ferrite prepared in a molar ratio of 1:3.

The Cd, Zn, Cu and Pb concentrations in tested soil were 10, 329, 479, 946 mg kg-1, respectively.
The concentrations of available Si was 4430 mg·kg-1, and the available P concentrations was 1020 mg·kg-1.
The effects of FA on rice growth is shown in Fig. 1.
The concentration of available Cd was 6.7 μg·kg-1 in control, and the amount decreased by 78% at addition of 20 g·kg-1 FA, and the concentration was lower than the detection limit (0.5 μg·kg-1) in the treatment of FA40.

In a typical procedure,1.2g of crystalline V2O5 powder and 0.7g oxalic acid was dispersed in 50ml mixed solution which made up by water and HCl with a volume ratio of 50:0,150:1 and 80:1.
Results and discussion Fig.1.
However, compared the VO-1,VO-2 with VO-0, we found the peaks of the VO-1,VO-2 mildly moved in high-angle, that indicate the crystalline interplanar spacing of the VO-1,VO-2 have decreased.

Introduction Coagulant is very important in treating polluted waters[1-3].
And then, some stabilizer M (C4H4O6Na2·2H2O:NaClO=1:6.5) was added and the product PSF (Si/Fe molar ratio equals to 1) was diluted to Fe concentration of 10 g.l-1.
And then, some stabilizer M (C4H4O6Na2·2H2O:NaClO=1.5:6.5) was added and the product OPSF (Si/Fe molar ratio equals to 1) with w(DMDAAC) 7.5% was diluted to Fe concentration of 10 g.l-1.

Fig. 1 A three-lane freeway Fig. 2 Relationship between density and overtaking different ratio under control conditions As shown in Fig. 1, cars on lane 1 and lane 3 can change to lane 2 while cars on lane 2 can change to both lanes 1 and lane 3.
The distances between car in lane 2 and its adjacent front car in lane 1, lane 2 and lane 3 are defined as,,,.The distances between car in lane 2 and its following car in lane 1 and lane 3 are defined as and .The speed of car in lane 2 is defined as The speed of the following car in lane 1 and lane 3 are and .
Rule 1 Change from lane 1 to lane 2 if ,, (2) Change from lane 2 to lane 1 if ,,, (3) Change from lane 2 to lane 3 if , ,, (4) Change from lane 3 to lane 2 if ,,, (5) Rule 2 (The Keep-Right-Except-To-Pass Rule that is the cars on the passing lane are controlled) We only need to modify part of the Rule 1, and then we can get Rule 2(The Keep-Right-Except-To-Pass Rule), which is mentioned in question given.
Change from lane 1 to lane 2 if , (6) The rest part is the same as Rule 1.
