Double surplus have played an important part in economy of China, but on the other hand, it means export of our resources, which will restrict sustainable development of our country, besides, it result in the RMB revaluation pressure and loss of capital revue, will weaken control power of the central bank of China in money supply and effectiveness of monetary policy. Therefore we must pay more attention to it and deal with it cautiously.

双顺差对我国经济有着一定的积极意义，但另一方面却意味着大量实际资源的输出，会制约我国长期的可持续发展，造成人民币升值压力，会削弱央行对货币供应量的主导权和货币政策的有效性，带来资产收益损失等这些对我国经济的不良影响，因此，要慎重对待双顺差问题。

The main content of the dissertation is designing and realizing the total scheme and frame of system software. The module of the input and output is designed by using the generally I/O of the multichannel buffered serial port to simulated the communication of I~2C bus. The Ping-Pong buffer is brought forward to resolve the problem of the data rate matching. The logic switch function is designed in the programmed logic devices. The data transmission rate is improved by using the DMA and the dual buffer mechanism. The system program self-loading is realized by the design of the self-leading program. Lastly, the dissertation analyzes the characteristic of LLL video and experimentalize with some typical image processing algorithm.

根据弹体动力学基本方程和假定混凝土为可压缩材料，基于弹靶接触表面处靶体材料的法向膨胀性，对跳弹现象进行理论分析，在合理假设的前提下，建立了跳弹现象的数学模型； 2）针对该模型编制计算机程序，在给定初始入射速度、入射角后可以判断出能否产生跳弹现象，输出产生跳弹现象时所对应的初始侵彻条件，并通过穷举法得出跳弹临界相图，对于斜侵入情况，能计算出弹体在不同侵彻阶段下的运行时间并能绘制出侵彻轨迹，结合现有的试验数据，进行对比分析，二者符合良好，证实了理论分析模型的合理性； 3）开展了跳弹现象的数值模拟研究。

The tenet of Vibroseis seismic exploration is outputting as much energy through a continuous bestirring in a period of time as that outputted by other sources in an instantaneous time. The realization of this goal needs that Vibroseis can output a same sweeping signal in many times continuously, then overlap the reflect signal to eliminate the noise from the exploration background, finally visualize the structure of the stratum.

可控震源地震勘探的精髓便是通过系统长时间的持续激励来实现其它震源的瞬时高能量激励，实现这一目标的前提是要求震源系统能够完成相同扫描信号的多次无差别输出，进而通过地震仪进行相应的垂直叠加，充分压制背景噪声，凸现地下的有用构造信息。

The microcontroller superposes the parameters with the video images from video tapes and then outputs to the monitor. While observing the outside activity of the athletes and understanding the inner parameter variations, users can make more precise judgments on how the exercise processes influence the body encumbrances.

其作用是把测量的参数通过单片机与监视录影将影像叠加在一起，最后在监视器上显示输出，可使监测者在观察运动员整体外部活动的同时，了解到其内部参量的变化，能更准确地判断人体负荷随著运动进程的变化所产生的的影响。

For the stability of the flow metering pumps, metering pump flow rate, as some big changes with pressure, you can set the exit of metering pump back-pressure valve, so that the output of metering pump flow rate stability, and then usually selected back-pressure valve The Reducing Valves pressure of the actual use of a metering pump metering pump pressure or slightly less than the use of pressure.

用于稳定计量泵的流量，如某些计量泵的流量随压力变化较大，可在计量泵的出口处设置背压阀，使计量泵的输出流量稳定，这时一般选择背压阀的压力为计量泵的实际使用压力或略小于计量泵的使用压力。
