When the LD incident power was 2.68 W, 2.7 mW and 24 mW free-running laser outputs at 731 nm have been obtained in the same plano-concave cavity, respectively. By using of 3.4 mm length laser rod, the overall efficiency of 1.4% and slope efficiency of 11.9% were gotten.

当激光二极管输入功率为2.68 W时，在平凹腔中祖母绿晶体分别实现了2.7 mW和24 mW的731 nm红外激光的自由输出，其中长度3.4 mm激光晶体的光-光转换效率为1.4%，斜率效率为11.9%，激光阈值在0.7 W附近，并分析讨论了效率低的原因。

Therefore, high efficiency can be achieved. The circuit parameters are decided according to the intrinsic impedance of the resonant tank. As the duty ratios of the active switches are fixed, the charging current should be programmed via tuning the circuit operation frequency and therefore the circuit impedance. The optimum operating point is sieved by the frequency response diagram to operate the charger at high efficiency.

至於并联负载电路参数的设计是以共振槽的特性阻抗为基准，调变切换频率并固定主动开关的责任周期，藉由频率的变化改变电路阻抗，以控制充电电流的大小，透过频率响应立体图，挑选适当的操作点，使共振式充电器运作於最佳状态，以获得高效率。

这一趋势变化也与苗期玉米试验的结果基本吻合，说明改性磷矿粉的颗粒减小程度和粗糙程度的增加幅度和能与其生物有效性存在一定相关。

Finally, experimental results show that the efficiency of push-pull forward converter with full-wave rectifier is over 89%, which establishes the foundation of the novel aircraft static inverter's efficiency exceeding 85%.

实验表明，采用全波整流的推挽正激变换器效率可以达到89%以上，为新型航空静止变流器效率超过85%奠定了基础。

The furring thickness of water pipe is the worst factors, along with the increasing of furring thickness, both the temperature and efficiency reduced. Secondly, when wax thickness of oil pipe enhanced, the media temperature at outlet increases, but the efficiency reduces.

不利因素中影响最大的是伴热管道结水垢，随着水垢厚度的增加，油出口温度及伴热效率都降低；其次是油管结蜡，随着油管结蜡厚度的增加，油出口温度有所增加，但伴热效率降低。

Beauv effectively, and bensulfuron methyl (30g/hm^2) applied 6 d after rice transplanting could significantly reduce the plant numbers and biomass accumulation of difformed galingale (Cyperus difformis L.) and procumbent falsepimperne . The control efficiency of Huakangcao 78 and Yangdao 6 were 89.16% and 81.86% on barnyardgrass dry weight respectively 50 d after the rice transplanting, 83.56% and 84.93% on difformed galingale dry weight, 95.22% and 88.04% on procumbent falsepimperne dry weight. As a whole, the total dry weight control efficiency were 87.68% and 82.69% on above weeds correspondingly. Moreover, the grain yield of Huakangcao 78 and Yangdao 6 under the condition of 10cm depth water and herbicide application increased 40.33% and 21.36% comparing those under the treatment of 5cm depth water and no herbicide application respectively.
