This study proposes the improvement of the output performance of a resonant piezoelectric pump by adding proof masses to the free ends of the prongs of a U-shaped piezoelectric resonator. Simulation analyses show that the out-of-phase resonant frequency of the developed resonator can be tuned more efficiently within a more compact structure to the optimal operating frequency of the check valves by adjusting the thickness of the proof masses, which ensures that both the resonator and the check valves can operate at the best condition in a piezoelectric pump. A separable prototype piezoelectric pump composed of the proposed resonator and two diaphragm pumps was designed and fabricated with outline dimensions of 30 mm × 37 mm × 54 mm. Experimental results demonstrate remarkable improvements in the output performance and working efficiency of the piezoelectric pump. With the working fluid of liquid water and under a sinusoidal driving voltage of 298.5 Vpp, the miniature pump can achieve the maximum flow rate of 2258.9 mL/min with the highest volume efficiency of 77.1% and power consumption of 2.12 W under zero backpressure at 311/312 Hz, and the highest backpressure of 157.3 kPa under zero flow rate at 383 Hz.

As one of the most important parts of the financial organizations nowadays, banking industry plays an important role in not just the area of high-speed operation of the sociaty’s economy but also in the area of currency exchange. The Wave of Information Technology, which has caused a swift-development of the whole world’s economy, brings about both opportunity and challengs never arised to the banking industry. The sociaty, as it is becoming more intellectual and automatic, has post a harder demand for the working efficiency of the banking industry. Therefore, the banking industry must enhance its construction of informationization and automation in order to strengthern its competitiveness as well as the economic construction of service sociaty. Banking office automation will improve the working efficiency along with modernized management level in the light of advanced computer technology.

Quantum entangled state theory is combined with quantum thermodynamics theory to build quantum entangled state heat engine. The basic nature of three-qubit Hxx chain, and all parameters of the orbit are analyzed. Energy model of quantum entangled state refrigerator in working process is taken as as a theoretical basis to construct three qubits Hxx chain refrigerator based on quantum entangled states. The working nature of the new quantum entangled state refrigerator under different field strength is studied. Compaired with two-qubit Hxxx chain refrigerator based on quantum entangled states and mapping analysis, the working efficiency of three qubits Hxx chain refrigerator based on quantum entangled states is much higher when the field strength is not zero and its working state is more stable.

The paper presents the results of studies of grain crops row sowing method agrotechnical indicators after the modernization of the working bodies of the SZS-2.1 seeder-cultivator. The SZS-2,1 stubble cultivator seeder has found wide application in the arid regions of the Republic of Buryatia, whose soils are prone to wind erosion. This seeder provides a combination of pre-sowing cultivation, sowing grain crops, applying mineral fertilizers to the sown rows and rolling them on stubble backgrounds, that is, in fields that have been processed since autumn with flat-cutting tools or have not been cultivated at all. Sowing with these seeders with 23 cm row spacing in a row method is the main method of sowing spring wheat in the soil conservation agriculture system. Routine sowing on soils of light texture, subject to wind erosion, causes thickening of plants in a row, which leads to irrational use of the feeding area by plants, increased weediness of crops between rows and, ultimately, to a decrease in yield. A distributor for the coulter has been developed, where the seeds are fed to the distributor. Then, reflecting from the distributor, the seeds are evenly dispersed in the opener under the plow space. Also, instead of serial wedge-shaped packer rollers, ring-spur rollers of the 3KSH-6 type are installed on the seeder. In addition, continuous rolling provides the necessary contact of seeds with the soil, preserves soil moisture and helps to attract it from the lower layers. Thus, the modernization of the SZS-2.1 seeder made it possible to substantiate subsurface-spread strip sowing with continuous rolling, which ultimately led to an increase in grain yield by 10-15%.
