value of cultural relics and artistic also can not tear down which the walls,roofs,even roof trusses have already changed out of all recognition,and lost their use value.Some media confound right and wrong,add fuel to the fire,with so much talk about the idea those days.Almost 20 years,Beijing siheyuan is in a circle in protection and renovation of historic culture areas.The contradiction is do add up.Practice in 20 years has proved that,the view that all things can not change did not explore any roads for protection and renovation of Beijing siheyuan,but only waste and delay near 20 years precious time. 2.Protection and renovation of hutong street In order to make historical block and historical culture of Beijing,especially the living culture-siheyuan that people all cherish go on muchly,we must renew the hutong block organically according to the need of history and city development,to search for a kind of middle-of-the road solution.This article proposes that it should have truly professional
source.In consideration of the reasons above,a large number of architects devote themselves to explore the protection and rebirth of siheyuan buildings.Among these changes,some siheyuan buildings transform into senior business club,some other ones become private museum and so on.They separately inject new vitality into hutong block on the form and function. 3.1.Transformation in form of siheyuan In the eyes of many creative architects,traditional old Beijing siheyuan is too stiff and musty with no vitality of new age.Because of this,a lot of architects explore new forms actively.For example,the famous reform case of siheyuan called Hutong Bubble is designed by young famous architect Yansong Ma.The Hutong Bubble is located in Beibinmasi hutong no.32 of South Luogu Lane,Yansong Ma first communicate with the owner adequately,then change the nornal traditional siheyuan into the appearance we can see.Considering the need of rest room,Yansong Ma designed a bubble rest room like a big drop of water
There are many reconstructed cases like these with different characteristic which worth learning.However,walking in hutong streets,going into resident siheyuan,there are quite a number of siheyuan has not been improved yet,appearing chaotic form of megafamily still.Improving the resident living condition is needed by coordinate of every aspects:government support,the exploration of professionals and coordinate of residents..We have a long road to walk,if chinese traditional culture may be carried forward in a better way. 4.

Second, do analysis through professional software that can calculate the stress of each body part.
So, the software based on experiment combines the value of each joint and the results of lager numbers of experiments, and supply the designers professional tool.
After that, we can start our analysis using professional tools.

International professional literature recommends the LaPera etchant in order to determine whether the microstructure stereotypical of TRIP steels has evolved as a result of the applied heat treatment technology - that is, to inspect the microstructure through etching [2].
Reagent 1 Reagent 2 1g Na-metabisulphate (Na2S2O5) 4g picric acid (dry, C6H3N3O7) 100 cm3 distilled water 100 cm3 ethanol Table 3: Composition of the LaPera etchant applied during colour etching [2] The reagents can only be mixed directly before usage, because the etchant becomes ineffective very quickly.
The colour shades after colour etching do not always correspond to those put down in international professional literature.
Results yielded from colour etching do not always correspond to those put down in international professional literature.

This paper analyzes the characteristics of the super-size flow measurement in the water transportation and industrial projects, and the choice for suitable flow meters.
Furthermore, this paper analyzes the calibration data of water flow, and propose the segment and compensation method for discharging coefficient “C” practically.
Electromagnetic flow meter and the ultrasonic flowmeter is cited (for) the most widely used flow meter for the water industry.
In fact, blast furnace gas and water diversion project to use the classic venturi tube often beyond the scope of the standard requirements, special techniques need to be taken to ensure the accuracy of the measurement.
Figure 1 Flow coefficient C distribution diagram Calibration method for analysis of actual flow of the water flow According to ISO5167 specified in the throttling device (including the Venturi tube) flow measurement formula such as 1.

OVERVIEW Feng-shui (literally wind and water), Chinese geomancy, emerged gradually over thousands of years.
The Chinese characters for feng-shui, can be directly translated as "wind" and "water", To avoid wind and to have water is the basic premise in feng-shui site selection.
Yet most professional designers have little understanding of the methods of these traditional practitioners of the art.
The whole water network consisting of these streams also protects the city from flooding by releasing storm water.
Thus, water becomes the soul of the city.

A Regional Water Supply Project (Regional SPAM) is a water supply system dedicated to (i) treating, and (ii) supplying and selling bulk of water to several designated regions.
Hence, the existence of regional SPAM is expected to assist the existing local water companies (PDAMs) in treating water and supplying bulk water to the PDAMs water mains.
Water Treatment Plants Raw water will be extracted from the Rokan River, and it will be pumped to the water treatment plant located approximately 70-100 m from the river.
In the water treatment plan (WTP) facility, the raw water will be purified to become drinking water.
Adequate site investigations may reduce risks associated with ground conditions; recruitment of skilled and professional staff may reduce human error, as will procurement of equipment and materials from accredited suppliers at fixed prices.

Therefore professional information provided to the public concerning their harmful impact not only on construction materials but also on human health, is very necessary.
The survey of the object revealed many places (practically in all open areas of the ground floor) with traces of intense ingress of water through peripheral constructions (mainly the ceiling), some places include biological stains (mildew) and deteriorated coating.
In both cases we can conclude that direct infiltration of rain water into the construction is the primary source of excess humidity.
Conclusion The primary reason for mildew occurrence on the indoor surfaces in the examined rooms is the infiltration of moisture caused by rain water during the reconstruction of the roof.
After stopping the ingress of water, apt handling of surfaces aimed at mildew removal and proper usage of the inner rooms with respect to temperature-humidity mode, further occurrence and spreading of mildew can be prevented.
