On the basis of introducing the motor structure, the self-exciting converting principle of SCLRM under three-phase AC supply is described.

在介绍电机结构的基础上，深入分析了SCLRM在三相交流电源下的自激换流工作原理。

The system simulation model is implemented in PSPICE. The steady-state simulation performance of SCLRM in both self-exciting operation mode and inverter feeding mode are studied, and the effect on the steady-state performance by the motor parameters and the driving mode are also simulated, verified by the experimental results.

建立了基于PSPICE的系统仿真模型，对SCLRM在自激方式和逆变器驱动方式下的稳态运行特性进行了仿真计算，分析了电机参数及驱动方式对稳态电压、电流及电磁转矩的影响。

It also had a pretest of object control skills in TGMD-2 (Test of Gross Motor Development 2nd Edition : including: Strike a Stationary Ball, Stationary Dribble, Catch, Kick, Overhead Throw, Underhand Roll), followed by another six weeks of lessons in games, at last there was a posttest a week after the lessons. This research analyzed the data by repeated measures t-test, and the level of significance was α=.05. Regarding quality, we promoted the teachers specialty through the process of designing games, teaching, practicing, self-examining and improving.

并於游戏课程介入前一周进行TGMD-2操作性动作技能的前测（包括定点击球、原地运球、踢球、接球、高手投掷、低手滚球），接著进行为期六周的游戏课程，且於课程结束后一周进行后测，研究所得资料以相依样本t考验进行统计分析，并将研究之统计显著水准介定在α=。05；在质的部份，藉由游戏教学设计、实践、反思、修正的历程，来提升教师之专业。

In this way, the automatic control, the centralized control and the intelligent self-disposal functions of the motor protection is realized.

这样真正实现了电动机保护的智能保护、集中监控和管理。

The motor is a dry-running self-cooled type with a non-hygroscopic Class F (155℃) insulation system rated for continuous duty in 40℃ ambient liquid with

所配置的电机是干转自动冷却型、防潮F级(155℃)绝缘系统，在环境流体介质温度达到40℃下，仍能够连续运转，安全系数达到

FGS100L-4 three phase cage induction motor is completely enclosed and self-cooled.

本型电动机是封闭式自冷式鼠笼型三相异步电动机。

The motor is a dry-running self-cooled type with a non-hygroscopic Class F (155oC) insulation system rated for continuous duty in 40oC ambient liquid with

所配置的电机是干转自动冷却型、防潮F级（155oC）绝缘系统，在环境流体介质温度达到40oC下，仍能够连续运转，安全系数达到

The reason of low system efficiency of the mechanical lifting is: unavailable match between transformer and asynchronous motor with large capacity of equipment and large self-consumption; large average no load less of Y series electrical machinery (31.4% of the total oilfield electrical machinery) with 2.86kw; limited adjustable extent of stroke of the electrical machinery in low-liquid produced wells with minimum value of 4 times per minute for limitation of minimum rotation of the electrical machinery and minimum arc of contact of pulley. Energy consumption will be waste for 1 to 1.5 times per minute is enough.

分析显示，造成抽油机系统效率低的原因主要是：变压器与异步电动机之间匹配方式不合理，设备容量大，自身损耗大；占油田电机总量31.4%的Y系列电机的平均空载损耗大，为2.86kW；低产液井电机的冲次可调范围有限，受电机最低转度和皮带轮最小包角限制，其最小冲次仅可调到4次／min，但1~1.5次／min的冲次即可满足生产需要，造成能耗浪费。

Since 1958, cutting and felling of bamboo and trees by villages and other cooperative organizations under villages have been included in forestry; value of barnyard manure has been excluded from animal husbandry; self-consumed handicrafts has been excluded from sideline occupations, while the output value of industries run by villages and cooperative organizations under village had been included in sideline occupations and the output value of fish catches by motor fishing boats has been added to fishery.

1957年以前的农业总产值中包括了厩肥和农民自给性手工业（如农民自制衣服、鞋、袜，自己从事粮食初步加工等）。1958年及以后的农业总产值，林业中增加了村及村以下竹木采伐产值；牧业中取消了厩肥产值；副业中取消了农民自给性手工业产值，增加了村及村以下办的工业产值；渔业中增加了海洋捕捞水产品产值。1980年及以后的农业总产值，在副业中增加了农民家庭兼营工业商品部分的产值。
