为了确保电力动车组平稳安全通过高压接触网分相区段,提出电力动车组过分相的控制方法.主控车将微机系统从监控系统实时接收的监控信息(包括分相区信息)发送给从控车,结合路况信息和运行信息进行过分相控制,可以获知动车组与预告、强迫信号之间准确距离,避免动车组重载、车列较长或分相区坡度较大时,在分相区内停车的情况出现.

为了彻底解决HXN3B型内燃机车接触器有效动作采取不及时和显示屏实时数据显示有延时的问题,对可能造成延时问题的原因进行分析,最终得出结论:机车数据交互过程中传输数据量大,使CAN总线负载率高,在紧急情况下造成了关键数据的收发不及时,导致数据显示延时和有效动作施加不及时.因此提出了缩短关键数据发送周期和其他数据请求发送的解决方案,彻底地解决了数据传输延时的问题.

介绍了一种用斩波器实现内燃机车主发电机励磁控制的装置.由机车蓄电池或直流供电模块为励磁回路提供直流电源,斩波器根据励磁电流给定和反馈调节产生开关信号,对该直流电源降压斩波实现主发励磁回路电流可调,同时斩波器控制模块为主发励磁提供放电回路.该励磁控制策略控制精度高、响应速度快、结构紧凑、易于维护.

提出了HXN3B型内燃机车显示屏完全自主化的解决方案.选定Windows XP Embedded嵌入式操作系统,使用VC和VB语言进行应用层信息传输和界面显示的代码编写.通过运用考核,机车显示屏工作正常,达到了预期的目标.

从成盆、成源、成烃和成藏4个方面对海拉尔盆地乌尔逊-贝尔凹陷各构造演化阶段的石油地质意义进行了分析.海拉尔盆地成盆的动力机制是中蒙边界区中生代推覆构造形成后的晚造山期伸展垮塌作用,为典型的被动裂陷盆地.乌尔逊-贝尔凹陷形成演化经历了5个时期:山间残留阶段、被动裂陷阶段、主动裂陷阶段、断坳转化阶段和坳陷阶段.被动裂陷阶段沉积物震荡式沉积形成南一段中部砂泥互层的优质烃源岩;主动裂陷阶段盆地强烈裂陷,窄而深的断陷结构控制盆地南一段上部有效源岩分布;断坳转化阶段盆地快速沉降促进烃源岩熟化,伊敏组沉积晚期烃源岩大量排烃控制形成早期原生油藏,伊敏组末期盆地反转,部分油藏受活动断裂破坏调整到大磨拐河组形成次生油藏.不同演化阶段形成多种类型的隆起带,构成有利的油气聚集区带,控制了不同含油气系统油气聚集.

The structure for the software and hardware, the technical features and main technical parame-ters of the auxiliary inverter are discussed. The new techniques such as space vector algorithm and overshoot algorithm used in the system were described. The test of auxiliary inverter was discussed.

The software and hardware structure,technic characteristics,main functions and the control functions realised in diesel locomotive are discribed in the paper.The new technologies utilized in the system are analysed in detail.The starting and shut-down protection procedures are discussed.

By a study on source rocks and their space distribution characteristics,the deep layer in the Xujiaweizi fault depression is divided into three gas-bearing systems,which are K1sh+yc-K1d2,K1d2-K1q1+2 and K1sh+yc-K1q1+2.The main controlling factors of the deep gas reservoir forming are gas resource rock,cap rock,fault,and unconformity surface.Three gas-bearing systems of the Xujiaweizi fault depression are formed in different periods.There are four reservoir forming patterns.The accumulation periods and forming patterns of gas are controlled by the formation and evolvement periods of the gas-bearing systems.

There are 6 kinds of oil and gas reservoir in west slope of the north of Songliao basin: anticline reservoir,structural-lithology reservoir,lithology updip pinchout reservoir,lens reservoir,fault screened hydrocarbon reservoir and stratigraphic unconformity reservoir.The main target stratum are Gaotaizi and Saertu.On the basis of studying the oil and gas reservoir type and characteristic, through analyzing the distributed law and pool forming period,summarizing 6 kinds of pool-forming pattern of hydrocarbon migration and accumulation: stratigraphic unconformity trap pool-forming pattern;sand updip pinchout trap pool-forming pattern;structure and structural-lithology trap pool-forming pattern;fault-lithology trap pool-forming pattern;fault screened trap pool-forming pattern and sand lens trap pool-forming pattern.And confirming main control factors of pool-forming and distribution.

Technical characteristics and main parts functions and technical parameters for AC traction system of CKD8E diesel locomotive were introduced.Also deseribed was the working principle of the power circuit and control system,along with the new technical characteristics and working procedure at traction/braking made of eletric drive system.
