It is similar with normal induction motor with high efficiency and power factor while operation with the adoption of parallel star-shape connection and nonparticipation of appended interspaced resistor. During starting stage the adoption of unique serial triangle connection with the participation of appended interspaced resistor improves the starting performance with the character of low start current and high start torque.

它正常运行时，采用并联星形连接，使得中间附加电阻不参与运行，其运行性能类似于普通感应电动机，具有较高的效率和功率因数；而在起动时，采用独特的串联三角形连接，使得中间附加电阻参与运行，相当于转子电阻增加，从而有着起动电流小、起动转矩高的优良的起动性能。

It is admitted that incident management tackling nonrecurrent congestion is the primary factor that guarantees large volume, security and efficiency of freeways.

各国的研究与实践证明高速公路运营管理的关键是应对偶发性拥挤的交通事件管理系统，它是实现高速公路大流量、快速和安全的保证。

It is admitted that incident management tackling nonrecurrent congestion is the primary factor that guarantees large volume, security and efficiency of freeways. Hence the study on how to effectively use incident management technologies to enhance the operation on freeways is a critical research field in traffic engineering.

其中的原因除了我国目前人们的交通意识差、管理部门职责不明等人为客观因素外，最重要的是我国高速公路建设中高速公路管理系统基础设施的相对不足和落后以及高速公路运行中监控和管理技术水平低下。

In general, operating at a higher basis weight gives a better total displacement ratio, and Norden efficiency factor.

较高的单位面积浆量时，总置换比及诺顿效率因子普遍较高。

The system not only can measure the outer and dynamic characteristics and static electric parameters, but also can measure three- phase power factor, input harmonic current and frequency spectrum, and efficiency of arc welding machine.

系统不仅具有测量外特性、动特性、静态参数、电焊机温升等传统电焊机测试台所有的功能，同时还可以测量三相功率因数、输入端电流谐波和频谱分析、弧焊电源效率的功能。

The results showed that the diurnal changes of photosynthesis of S. chinensis in tile overstory took on "double-peak" curve with remarkable midday depression. The midday depression was mainly due to non-stomata1 limitations. On the contrary, the diurnal changes of photosynthesis of S. chinensis in the understory took on "one-peak" curve with low Pn. The maximal Pn was only half of that of S. chinensis in the overstory. The correlation analysis showed that the limiting factor for this low Pn might be light intensity (p=0.001). Compared with its accompanying plants, S. chinensis was in a disadvantaged status in the community with low photosynthetic capacity, water use efficiency, and the ratio of photosynthetic rate to respiration rate.

结果表明：夏蜡梅冠层的光合速率日进程呈"双峰"曲线，有明显的"午休"现象，经分析其"午休"的原因主要是由非气孔因素引起的；林下夏蜡梅则表现为"单峰"曲线，净光合速率较低，最大净光合速率不及冠层的1/2，相关分析结果表明其最重要的影响因子是光合有效辐射(p=0.001)；与其它伴生植物相比，夏蜡梅的日均光合速率、最大光合速率、水分利用效率和光合速率／呼吸速率都明显偏低，在群落竞争中处于不利地位。
