Experience in the class struggle in the era of imperialism teaches us that it is only by the power of the gun that the working class and the labouring masses can defeat the armed bourgeoisie and landlords; in this sense we may say that only with guns can the whole world be transformed.

帝国主义时代的阶级斗争的经验告诉我们：工人阶级和劳动群众，只有用枪杆子的力量才能战胜武装的资产阶级和地主；在这个意义上，我们可以说，整个世界只有用枪杆子才可能改造。

To Temperance he ascribes his long-continued health, and what is still left to him of a good constitution; to Industry and Frugality, the early easiness of his circumstances and acquisition of his fortune, with all that knowledge that enabled him to be a useful citizen, and obtained for him some degree of reputation among the learned; to Sincerity and Justice, the confidence of his country, and the honorable employs it conferred upon him, and to the joint influence of the whole mass of he virtues, even in the imperfect state he was able to acquire them, all that evenness of temper, and that cheerfulness in conversation, which makes his company still sought for, and agreeable even to his young acquaintance.

他认为他的长寿健康应归功于节制，直到现在他仍旧拥有一个强壮的体格；早年境遇之顺适，财富之获得应归功于勤俭，而以一切的知识使他能成为一个有用的公民，并且在学者中得到相当的名誉；国人对他的信仰应归功于诚恳和公平，以此赋予尊荣的地位，而所有一切美德之关联的影响，就算他所能得到的是不完全的状态，一切温和的态度，和愉快的谈话，这使他的同伴或甚至他的年轻朋友仍旧欢迎他，我以此希望我的子孙中有几个能够奉行这个例子，因而获得有用的效果。8 |' K， Y+ T/ W$ z9 q/ N

Abstracts: To sample high speed random signals without drop, a design of O-shaped high speed random signals acquisition card based on the CPLD and its realization are presented. It consists of same three sets of acquisitive circuits, which construct O-shaped structure to sample the signals without drop .And it adopts threshold judging method to determine the valid data in the process of the acquisition, abandons vast of the redundant useless data at the same time, it only sends the useful data to the host computer by the way of DMA, so it is easy to processing the data. The design is concise and reliable. The sketch map of the logic circuit and the explanation of the main parts are presented. This design has been applied in the engineering project of sampling α nuclide.

为了对随机到来的信号进行不丢失的高速采集，提出了一种基于CPLD的随机信号环形高速采集卡的设计与实现；通过采用三套采集电路形成一个环形结构，可以对随机到来的信号进行不遗漏的高速采集，而且在采集过程中利用阈值的方法鉴别出有用信号，并舍弃了大量的冗余无用数据，从而只将有用数据以DMA的方式传于主机，便于进行信号的处理；电路设计简洁可靠，并给出了主要的逻辑电路示意图与主要部件说明；该系统已经应用在采集α核素的工程实践中。
