SDS、SAS总分均高于常模且在统计学上有显著性差异(P.01)，与年龄相关性无统计学意义。

Simian3 and Shiyuan321 as control. It showed that both GK12 and SGK321 had no significant impacts on natural control efficacy of the biological and non-biological death factors of cotton aphids. Except for the factor of natural death and others, predation was the key factor affecting population dynamics of cotton aphid. Rain ranked the second, parasitism by insects and pathogens had weak control efficacy.

与常规棉相比，单，双价抗虫棉对天敌捕食和寄生，病原物，风雨等生物和非生物因素对棉蚜种群的自然控制作用均未产生显著影响；各因素中，除自然死亡及未知因素死亡外，天敌捕食对棉蚜自然种群的控制作用最强，风雨的作用次之，天敌寄生和病原物的作用则较弱。

The experimental results indicate that the crest factor of the lamp current is 1.41 when the output power of the fluorescent lamp is 36 W. The power factor is 0.99 and the efficiency of the ballast is 91% when the system is in utility grid-connected.

The power factor, energy efficiency, electronic loss, lumen/w. and crest factor of 2×36 W electroinc ballasts based on these two dimming methods are recoded and Compared over a wide dimming range.

在宽的调光范围内，记录并对比了基于这两种调光方法的2×36W电子镇流器的功率因数、能量效率、电子损耗、单位功率光通量以及峰值系数。

The most important factor influencing implant survival in sinus augmentation, besides individual surgical technique, is the preexisting bone height between the sinus floor and alveolar crest. The key factor for success is to achieve primary stability. When the available bone height is less than 5mm or the thickness of the cortical bone is inadequate, two stage protocol (elevating the sinus floor to create sufficient bone height first, and then placing the implant at the second stage) is a safe, predictable treatment modality.

上颚窦植牙手术的成功与否，除个人手术技巧外，常取决於剩余齿槽骨之高度(residual bone height， RBH)，如何得到初期稳定度是一重要之关键，当可利用之齿槽骨高度小於5mm或皮质骨宽度不足以支撑植体获得理想初期稳定度时，分二阶段先提高上颚窦高度再植牙，不失为一理想，安全且可预期性高之植牙方法。
