The key to counter collusion tender is to introduce continuously new bidding enterprises and companies in bids, keeping the bidders different each time in bidding to destroy prerequisites leading to repeated games.
Materials about working experiences in the bidding party should be required to show, like certificates on pension and medical insurance provided by the local institutions of labor protection.

Design of Planetary Gear Reducer with Double Circular-Arc Helical Gear Chin-Yu Wang1, a 1Department of Mechanical Engineering, Cheng Shiu University, Taiwan, R.O.C.
If compared to the involute helical-spur gear drive of the same size and material, the bearing capacity of the tooth surface would be 2~3 times higher.
Another key point in the researches of circular-arc helical gears is about errors.
If similar bearing torque and the same material is used and the rotation condition is not changed, the volume of power winch can be reduced, cost can be lowered and flexibility of the miniaturization design can be improved because gears with smaller modulus can be used in the design of double circular-arc helical gear.

The suggestions to solve the problems The healthy living environment Healthy living environment designing means to design healthy,comfortable and safety space quality of living environment.Both the comfortable and safety outdoor wind environment,the space environment with smooth ventilation are the keys of living environment designing.In order to avoid the influence of high-rise residential wind environment, we can take the measures to improve as follows:Firstly,on the arrangement and distribution of building group,we can use the ladder form with high middle and low around.In the middle is the highest building,the surrounding buildings’ heights are decreasing,so that can build good streamline building outlines designing with rich layering.
In the aspect of residential itself,we can ues the low carbon building materials to reduce the waste of energy and pollution;In the aspect of living environment,we should pay attention to the balance of ecological and economic benefits’ combination,rational utilize the local natural resources,reduce the use of hard site to expand the natural afforestation.Processing the transitharmonious relationship between residential,afforest and human,ensure the fusion of construction and natural environment,and the harmonious communication between human and nature.
