Chicks were dying prematurely because of the cuts , the paper reported .

重点：中国拉闸限电。

The main point : China rationing power .

比起拉闸限电，很多企业更愿意接受更高电价。

Most businesses will be more willing to accept higher prices than power cuts .

由于拉闸限电，使用电单位内一些较重要部门的供电也不能得到保障。

在河北省张北县，本月初开始的拉闸限电，造成发电机热销。

In Zhangbei County in Hebei Province , electricity cuts that started earlier this month have caused a boom in sales of generators .

如果预测的需求滞后于实际需求，将会导致供电负荷紧张，甚至造成拉闸限电。

If the expected demand was less than the actual demand , it would cause the shortage of power supply , even limited usage .

研究的经济背景和问题的提出（1）研究的经济背景最近几年，我国不断出现民工荒、技工荒、煤荒、油荒、拉闸限电等现象。

In recent years , many serious economic problems such as peasant workers shortage , technical workers shortage , oil shortage , coal shortage , constantly occurred .

为了完成节能减排任务，全国多个省份采取拉闸限电的做法，有些地方甚至在寒冬时期停止供暖。

In order to complete the task of energy saving and emission reduction , many provinces take a switch power brownouts practice , some places even in winter time stop heating .

随着经济的发展，我国电力供需矛盾日益凸显，大部分地区先后采取措施拉闸限电。

With economic development , China has seen an increasingly serious conflict between electricity supply and demand . In some areas , measures like power cuts have been taken to limit consumption .

特别是夏季用电高峰时，供需矛盾更为严重，一些企业不得不承受拉闸限电的痛苦，企业利益严重受损。

Especially the summer peak , the contradiction between supply and demand more serious when , a few enterprises have to bear the pain of switch power brownouts badly damaged , company profit .

全国范围内的拉闸限电，不仅严重影响了工业生产，给人民生活带来极大的不便，还导致了一系列的社会问题。

The electric power shortage in nation-wide scope not only has seriously affected the industrial production and brought great inconvenience to people 's life , but also has caused a series of social problem .

1992年，重庆电网缺电情况十分严重，拉闸限电非常频繁，严重制约了工农业发展及对人民正常生活造成严重影响。

In 1992 , the electricity net was seriously short of electricity and it was very frequent to pull and limit strobe , which restrict badly the development of agriculture and industry and affected people 's normal life .

对用电负荷进行有效的管理和控制可改善负荷曲线，提高发供电设备的利用率，可防止拉闸限电，避免影响社会生产和生活。

By effectively managing and controlling of electric load , we can improve load curve and advance using rate of Power Supply equipment , which can prevent from drawing strobe and limiting electricity and avoid affecting social produce and life .

随着近年来全国特别是上海拉闸限电现象的逐渐增多，提高用电效能、尤其是提高工业用电效能已成为当前迫切需要解决的问题。

In recent years , with increasing phenomenon of the restriction of electricity in the whole country especially in Shanghai , it thus becomes an urgent problem to be solved to improve the efficiency of power comsumption , especially that of industrial enterprises .

我国新开工建设的电站占全世界的八成以上，但2011上半年全国在干旱、电煤价格上涨等因素的影响下，一些西部欠发达地区出现了拉闸限电的现象。

More than 80 percent of the power plants under construction in the world are in China . Nevertheless , in the first half of 2011 , some undeveloped areas in the west of China suffered electricity shortage due to drought and price growth of electricity and coal .

然而，供需矛盾的缓解不能仅仅依靠拉闸限电，还需西电东输、发电机组规模的扩大等。而电力行业的发展需要大量的资金投入及国家的产业政策扶持。

However , in order to relieve the conflict , more measures are needed such as " West-East electricity transmission project ", and the expansion in size of the generating units , etc. The development of power industry requires a lot of capital investment and the support of industrial policy .
