This electronic tide diagram is simple, convenient and practical. By the help of this diagram, mariners can easily find accurate tide height at any time of each tide station. It has a practical value to relax the mariners' work load and reduce errors that may arise to ensure the safety of navigation.keywords : paper "Tide Table" electronic tide diagram, shiphandling, pilotage

Taking the high precision on chip RTC as the time base control unit and using genetic algorithms to search the best OSCCAL register value, it will make the on chip RC oscillator generate a high precision clock for the MCU. This methord can be used fast and real time, so the CPU will get a stable clock source.

以AVR片内高精度时钟单元RTC为时基控制单元，以标准时间内MCU定时器的计数值为控制目标，采用遗传控制策略搜索对应MCU理想时钟频率的OSCCAL寄存器最佳设置值，快速、准确地对RC振荡频率进行校准，为CPU提供具有高抗干扰特性的精确时钟。

The discovery of manuscript C, however, disproved this hypothesis, since this manuscript reproduces with exactness the greater part of the variants of B, even when they are obviously false, while the transcriber of this latter manuscript discharged his task with such scrupulous care that he even recorded variants which were meaningless.

发现的手稿里，然而，反驳这一假设，因为这与精确再现原稿的较大部分的B的变种，即使他们显然是虚假的，而后者transcriber本手稿履行其承担的任务，例如，他一丝不苟地照顾即使记录变种是毫无意义的。

This trigonometric polynomial can be used to construct open and closed curves. Moreover, the class of piecewise trigonometric polynomial curves can be accurate and flexible to express ellipse.

The acceleration is indispensable as a state-variable for precise analysis of the dynamic response of a drive system. This is because it represents the direct, undelayed response of a mass being moved in reaction to all the forces acting on it.

加速度是必不可少的一对驱动器的系统，这是因为它代表着直接的，毫不拖延地的群众正在反应，反应的所有部队行事提出精确的分析动态响应状态变量。

It is my belief that much unnecessary perplexity can be avoided if we limit ourselves strictly to the two units, money and labour, when we are dealing with the behaviour of the economic system as a whole; reserving the use of units of particular outputs and equipments to the occasions when we are analysing the output of individual firms or industries in isolation; and the use of vague concepts, such as the quantity of output as a whole, the quantity of capital equipment as a whole and the general level of prices, to the occasions when we are attempting some historical comparison which is within certain limits avowedly unprecise and approximate.

我相信，当我们论述整个经济体系的行为时，如果我们将自己的讨论严格限定于使用两种单位，即货币和劳动，那就可以避免很多不必要的困惑和混乱。当我们孤立地分析单个厂商或单个行业的产出时，可以在这种情形继续使用特定产出和设备的原用单位。当我们试图进行某种历史比较时，可以在这种情形使用诸如总产出数量，总资本设备量和一般价格水平之类含糊不清的概念，这是因为在一定限度内，历史的比较本来就是不精确的和粗略的。
