查询词典 on the turn

In the design of the power supply, the main circuit topology frame uses full-bridge series resonant switching and parallel load connection, in which, four MOSFETs are adopted as the power switches, and by four pulses which UC3879 produces, high frequency operation and fast response are realized. In addition, the MOSFET in the switching power supply has no hard turn-on or turn-off situation in transition, thus the disturbance to the power system is avoided. Especially,by the use of high frequency transformer, PQ50/50, the switching power system can provide the steady discharge current without any amperite.

此开关电源采用全桥软开关技术、串联谐振并联输出，四个MOSFET管为主控制开关元件，通过脉冲产生电路UC3879产生的四路相关脉冲实现了高频交替开关，同时能快速响应输出的各种变化；避免了开关管的硬开关，提高了转换效率，另外通过采用高频变压器PQ50/50隔离了原副边，减小了高次谐波对电网干扰；无需镇流电阻也可实现气体稳定放电。

Focusing on them, author has been investigating in open country and collecting, arraging and analyzing material for one and a half year. After having done the study on the new deep prediction, author presents new opinion on the base of part of precious geological opinion .1, Xiaohe deposit direction and turn are mainly controlled by the second structure rochet vault in the back of Bigsnown mountain. It is conjectured that the axis extent with the current direction to the 180# exploring line and turn to northwest-southeast direction. During the extension, the deposit body would extend from deep to low instead from low to deep. The turning place was level corresponding to the core of rocket vault.2, There are a chain of radiate blind regmagenesis controlled by the rocket vault.

笔者针对这两个问题，通过一年半的野外实地调查和室内资料收集整理分析，在进行了新的深部找矿研究工作之后，在认同前人部分地质观点(即小河～石门坎矿带的连续是存在的)的基础之上，又提出了新的观点，即： 1、小河矿床矿体的走向及转向位置主要受大雪山背斜的次级构造火箭山穹隆控制，推测其轴线将沿现在的走向，延伸至180#勘探线附近发生转向，轴线方向逐渐转为北西——南东方向，同时矿体从由浅至深逐渐变为由深至浅的延伸状态。
