In the voltage doubling rectifying circuit, the high voltage has been realized by the positive and negative way, and the voltage between the cathode and anode could reach 1700 V. In the fly-back switching high-voltage power supply, considering the requirements of each unit of the driving circuits on the power supply, the three-group voltage outputs including low-voltage outputs have been realized: 1600V/20mA,12V/500mA, 5V/50mA, in which UC3842 has been used to achieve pulse width modulation.
在倍压整流电路设计中,采用正、负电压方式实现高压,有效降低了阴阳极间所需的高压,最终两极间可产生1700V电压;在反激式开关电源电路设计中,利用UC3842芯片实现PWM调制,考虑到驱动电路各单元对电源的需求,设计了包括低压电源在内的三组电源输出:1600V/20mA,12V/500mA,5V/50mA。

Based on the tensor expression for the Breit-Pauli Hamiltonian,and with the aid of irreducible tensor theory,the theory of relativistic corrections to the non-relativistic energies of many-electron atoms has been generalized to the case in which Racah wave functions are the linear combinations of multi-Slater wave functions,analytic formulism for calculating the relativistic corrections,which include mass correction,one-and two-body Darwin correction and spin-spin contact interaction,has been derived,all the angular interactions and spin sums involved in the problem have been worked out explicitly by using irreducible theory.

And with these results, I delve further into the theoretical issues of MSP and the concentration is on a special class of MSP-Doob skeleton processes. Generalized limit distribution, limit distribution of these processes and conditions and the expressions for the existence of invariable measure of such processes are provided. Finally, these new results are then applied to queueing theory, reliability theory and inventory theory. A detailed study of GI/G/1 queuing model, parallel connection system model, water reservoir model and perishable inventory model is discussed. These models have already been investigated to some degree. In particular, as mentioned above, some scholars have already successfully applied the transient behavior theory of MSP to these models and transient distributions of main variables in such models have been obtained. However, the limit behavior has not been addressed. In this thesis, limit behavior of main variables in the above-mentioned models is established.

The great potentials for exploration of litho-stratigraphic reservoirs do not appear until new methods and technologies have been applied and in-depth understandings have been gained. In recent two or three years, big discoveries have been made in Jilin oilfield, in which 80 percent of reserves are found in some areas of thin sand-shale interbedding of its delta front. There still exist petroleum potentials amounting to 6×10^8 t for exploration in this area, especially in southern Songliao basin where the litho-stratigraphic traps will be more important domains and deserve extra attention. Hence, geologically speaking, this study on the hydrocarbon accumulation of litho-stratigraphic reservoirs in Songliao basin is of vital significance to exploration of the southern Songliao basin.
但通过新方法、新技术的应用和地质认识的不断深入,岩性-地层油气藏展现出了较大的勘探潜力,吉林油田近2-3年来的大发现和新增储量的80%是在有一定面积的三角洲前缘薄互层中获得的,在这个领域中仍有6×10^8t的石油资源有待勘探,特别是松辽盆地南部地层-岩性圈闭是未来油气勘探的重要领域,具有进一步解剖研究和勘探价值,因此,对松辽盆地岩性-地层油气藏成藏规律进行研究,对于松辽盆地南部勘探有着十分重要的意义。
