X-ray ,which is excited from the X ray tube, has one wavelength scope, that is energy scope. According to the elements to be analyzed, X ray is choused by filter, and reach the sample. Atoms in the sample will absorb the X ray energy and the decay to emit the special x ray. The X ray will be collected by the collimator into the detector active area, and transferred into electron signal, the signal also will be processed in to energy spectrum and related concentration data by pulse processor with software.

从X光管通过激发Excitation发射出来一定波长范围也就是说一定能量范围的X射线，结合所需要分析的目标元素，使用滤光轮选择对应的能量范围的X射线，照射到样品上，样品中含有的元素原子电子受到激发会发射出其特征的X射线，同样通过Collimator准直器收集一定孔径的X射线进入到检测器Detector，检测器将感应到的X射线转换为电信号，电信号经过脉冲处理器Pulse Processor结合软件进一步将电信号转换成为能谱图以及相关浓度信息。

The invention comprises the following steps: the user of the mobile communication terminal setting the power save mode, selecting the subdistrict search time and opening the holding period of the power source, judging and counting the exceeding time that the subdistrict power falling under the reference value according to the saved subdistrict search time, operating the power save mode, closing the working power source supplied by the battery and driving the timer with the minimum working power source if exceeding the saved subdistrict search time; opening the working power source, searching the subdistrict and maintaining the calling standby state if the overtiming.

包括步骤：移动通信终端的用户设置节电模式，选择小区搜索次数和打开电源的保存时间，以保存的小区搜索次数为根据，判断计数小区功率降到基准值以下的超过次数，如果超过上述保存的小区搜索次数，则运行节电模式，关闭电池供应的工作电源，以最小工作电源驱动定时器计时；比较判断结果是时间已超过时，打开工作电源，搜索小区，同时保持通话待机状态。

The first idea to deal with the packet loss is the new proposal of multitask ATM cells and the required new ADPCM encoder. This scheme combines three tasks together, namely, reducing cell packeting delay, avoiding breakdown of speech decoders due to one lost cell, compensating or replacing the lost information segment, by dividing the cell payload field into two parts——main and additional information fields, the latter again consists of synchronization information and the coded speech information contained in the last cell.

首先以ATM网络为例，提出了新的信息分组多任务装配法，以及对应此方法的新型ADPCM语音编码系统，这种方法中，利用特殊设计的编码器，使ATM信元负载信息域，由主要和附加用户信息两部分组成，后者又由同步信息和前一个信元语音段信息组成，通过选择和调节信元中两部分信息域的比例，实现了小的分组装配时延、高的分组丢失补偿质量、强的阻断误差传递功能三者的结合。
