Abstract: Finding out the parameters with strong reflecting ability to construct recognition function can improve effectively identifying precision on complicatesets of geophysics data.
The reason we do not use the potassium item in the calculation is that the feldspar rock fragments with rich volcanoclastic rock in potassium is less; according to the analysis data of core slice, the tuff of andesite and the volcanic breccia's fractures are both mainly filled by altered material in Hailaer, and the tuff of rhyolite shows good porosity or finer particles and high content of irreducible water.

There is great harm on the power facilities such as tower and transfer substations built in the area: the mined-out area foundation occurs horizontal deformation since the basis of the power facilities is generally brittle material which has lower tensile strength and high compressive strength.

Although the two parts are interrelated, there are optimization requirements applicable to each other, but because of the failure of the main form of V-belt is slipping and fatigue two, the work of the tight side tension stress δi, centrifugal tension δc and tight around the edges small pulley caused the maximum bending stress δb, and with the periodic cycle of alternating stress are related to the diameter of the pulley, so the V-belt transmission design are generally based on work requirements and conditions of the first engineering design of V-belt, and then to transmission ratio, based on the principles of design in accordance with optimal diameter pulley, the pulley in addition to considering the design fits in with the V-belt, but also involves a wide range of issues, both from the weight, strength, and V-belt friction coefficient, etc. consider choosing the right material, but also consider the appropriate structure, process and precision; such as the use of cast iron casting material
V pulley system of multi-objective optimization The V pulley system design must consider the factors and principles are ① the first transmission ratio to meet the requirements. ② to meet with the V-belt with the most optimized, including the maximum possible friction factor, V with a maximum working stress at work as a minimum to ensure that no failure, and so on. ③ to minimize the weight of the pulley. ④ should be installed in all the host of the main pulley above the total moment of inertia as small, to reduce the moment of inertia, reducing the vibration of the host. ⑤ to meet the strength requirements of the premise of lower prices of materials used, while the size of the pulley as much as possible, consistent structure to reduce manufacturing costs.

Heidimiao reservoir forming in period of third Member to forth Member of Nenjiang Group, under the control of the northern material sources, is of the river-delta depositional systems which formed in the gradual uplift basin-shrinking tectonic settings and the proximal small water systems tectonic settings.
Studis on macrofacies impact: (1) At the time of the bottom of Heidimiao Reservoir depositing, base levels was relatively high, accommodation was relatively large and material supply from the Southeast was relatively strong.
(2) At the time of the middle of Heidimiao Reservoir depositing, base levels fell, accommodation decreased and material supply was not strong.
(3) At the time of the top of Heidimiao Reservoir depositing, base levels was relatively low and near to the shore, and the range of material supply became lager.

For example, the sensitive housefly raised in the laboratory can be used as the measuring material, the poisoning degree after contacting the measured samples is used to represent pesticide residues of the samples, the inhibited degree of pathogen growth is used to detect pesticide residue, and the inhibited degree of corn or other indicative plants is used to detect the sulfonylurea herbicide residue in soil.
But the carrier gas of gas chromatography has no influence on distribution, which means that in liquid chromatography, there are two phases which have selective interaction with samples. ② Liquid chromatography has many types of packing materials with unique efficiency, which makes the selection of stationary phase greater and increases the possibility of separation. ③ Liquid chromatography uses low separation temperature, the interaction between molecules is more effective in low temperature, so reducing the temperature can improve the efficiency of chromatographic separation
In many situations, liquid chromatography can be used as an analysis method and a separation method to purify and prepare single material with medium purification.
