Corn production increased by four and a half times, hay by five times, oats and wheat by seven times. The most crucial factor behind this phenomenal upsurge in productivity was the widespread adoption of labor-saving machinery by northern farmers. By 1850horse-drawn reaping machines that cut grain were being introduced into the major grain-growing regions of the country. Horse-powered threshing machines to separate the seeds from the plants were already in general use. However, it was the onset of the Civil War in 1861 that provided the great stimulus for the mechanization of northern agriculture. With much of the labor force inducted into the army and with grain prices on the rise, northern farmers rushed to avail themselves of the new labor-saving equipment. In 1860 there were approximately 80,000 reapers in the country; five years later there were 350,000.After the close of the war in 1865, machinery became ever more important in northern agriculture, and improved equipment was continually introduced. By 1880 a self-binding reaper had been perfected that not only cut the grain, but also gathered the stalks and bound them with twine. Threshing machines were also being improved and enlarged, and after 1870 they were increasingly powered by steam engines rather than by horses. Since steam-powered threshing machines were costly items — running from $ 1,000 to $4,000 — they were usually owned by custom thresher owners who then worked their way from farm to farm during the harvest season. Combines were also coming into use on the great wheat ranches in California and the Pacific Northwest. These ponderous machines — sometimes pulled by as many as 40 horses —reaped the grain, threshed it, and bagged it, all in one simultaneous operation.The adoption of labor-saving machinery had a profound effect upon the sale of agricultural operations in the northern states — allowing farmers to increase vastly their crop acreage. By the end of century, a farmer employing the new machinery could plant and harvest two and half times as much corn as a farmer had using hand methods 50 years before.1. What aspect of farming in the United States in the nineteenth century does the passage mainly discuss?(A) How labor-saving machinery increased crop Production(B) Why southern farms were not as successful as Successful as northern farms(C) Farming practices before the Civil War(D) The increase in the number of people farming2.

一、FANUC--OMC密级型(功能)参数FANUC--OMC系统参数可以分为两大类：一类：公开型参数——它是系统与机床有关设定的参数，这类参数在FANUC公开发表的各类资料中可以查到其各参数的含义，目前从FANUC有关资料中可查到约有1800多个参数。

有关公开型参数剖析，可在FANUC公司提供有关资料中可查到，不再在本文中论述。

另一类：密级型参数——它是FANUC系统的功能参数，这类参数都属于状态型参数。

每个参数既无名称和符号，也无说明。

这是在随机所带的参数表中有初始的设定值，每一个都代表某种功能的有，无。

只有这些参数的所代表的功能含义在FANUC所提供资料中是不提供任何解释。

FANUC—OMC中900--939参数，就是此类型参数。

它代表OMC系统许多功能。

按900--939号参数共40号，每个参数号为八位，40号参数共320个参数。

但是FANUC 公司没有全部设置，目前我们已了解到密级型参数约有80余个。

下面将对这些密级型参数进行剖析。

FANUC--OMC密级型(功能)参数又可以分成二类：一、基本功能参数：即FANUC公司在提供系统时的基本功能的参数，如下：二、选购功能参数：实际上选购功能中又分为两类：A、需要有硬件配合，(即除了将功能参数设置“1”外，还需有硬件的要求。

)可能在价格上要高一些。

B、不需要硬件配合实现该功能。

而目前FANUC--OMC系统提供时，大部分软件已固化在主板上，所以不需要硬件配合的功能，只要将相应功能参数位的状态设置为“1”即可开通该功能。

对于早期版本软件，有可能没有完全固化在主板上时，若当将该功能参数设置“1”后，系统可能不启动或死机时，重新将该功能参数置“0”即可恢复。

§2 功能参数设定方法和传输一、功能参数设定方法1、压住紧急开关，打开机器电源。

2、将方法开关设定在“MDI”方式。

(以下步骤请保持紧急开关在压住状态，不可打开)3、按压PARAMETER键，选择显示参数画面。
