At the same time, the agricultural structure and spatial distribution should be adjusted in order to facilitate the development of a mosaic configuration in order to create a harmonious complementary landuse practice that will be of mutual benefit to livestock, fisheries and pasture farming, promoting a sustainable eco-agricultural system. 3.3 Promote ecological treatment and improve the innovation capacity of water pollution control The present traditional approach, which does not incorporate innovative management concepts and methods of science and technology, is normally used to treat water pollution.
Science and technology should be used to solve technical problems in terms of rejuvenating the water environment.
Biological communities in the Qinhuai River and their environment, as well as different species in the biological community, have an ongoing exchange of material and energy, and are in a dynamic balance of interaction and mutual influence.

But there is also a significant causal link between material failures and material conflicts of interest that led to failure and then accident.
Hydrocarbon flame (left), hydrogen flame (right) [7] In addition to being flammable, hydrogen can easily permeate materials and in some cases even brittle them.
This can be avoided by selecting materials suitable for the expected load, as well as observing the appropriate operating conditions (gas pressure, temperature, mechanical stress).
For this reason, storage tanks are made of stainless steel and composite materials.

This shows that edible film has the potential to be a food packaging material, especially for oyster mushrooms, by utilizing materials available in nature [5].
However, the Hawthorn plant is a medicinal plant that is rarely found in Indonesia [6], so other alternative materials are needed that can be used as basic ingredients for making edible films.
Experimental Materials and apparatus.
The materials used are kepok banana peel, corn starch (brand name "Maizenaku"), ZnO; glycerol; sorbitol; sodium metabisulfite (with brand name “Sentra Chemicals”), technical acetic acid, silica gel, NaCl, and distilled water.

Simultaneously we also discover software itself some questions, which needs to carry on the revision and processing here. 2.1 Manual input parameter First we must carry on the definition to each components material attribute, which needs the manual input material performance parameter.
If in the following computation, there is no finite element analysis, then only the material density parameter is defined; otherwise, need to define the elasticity coefficient and the Poisson’s ratio; If there is heat transfer computation, then needs to define the material thermal conductivity and the linear expansion coefficient.
In order to simulate the whole hoisting process and include all motion process, we use super calculation equipment in Chinese Academy of Science Modern times Institute of physics.
At present, we use super computer at Chinese Academy of Science's Modern times Institute of physics to calculate the equipment, through the external cooperation, and have already solve the integrity computation of tower equipment hoisting process, including the steel wire, the crane, the tower equipment.

The second part of the paper presents a suggested method of maintenance optimisation in the case of a processing machine for dosing tiny loose material and smaller piece goods.
These scales serve to dose tiny loose material as well as smaller piece goods, e.g. screws, nuts, and also food like pasta, different granules, dried fruit, cereals, nuts etc., precisely.
The outage is given by the time which is left until the planned outage is performed, and also by the difference between full system performance (all n subsystems work) and performance of the system before the outage: . (9) Following other assumptions it is possible to exclude the costs related to spare parts once used and the material applied during repair and for labour force.
