Tabaci was the shortest (19.3 d) on hairy gourd and the longest (29.0 d) on bitter cucumber, the survival rate from egg to adult was the highest (92.85%) on cucumber and the lowest (53.08%) on bitter cucumber, the laid eggs were the most (187.4 eggs per female) on cucumber and the least (30.0 eggs per female) on bitter cucumber, and the longevity was the longest (25.2 d) on cucumber and the shortest (10.9 d) on bitter cucumber. The intrinsic rate of increase r(subscript mon cucumber, hairy gourd, bitter cucumber, and sponge gourd was 0.1453, 0.1429, 0.0616, and 0.1055, respectively.

结果表明，B型烟粉虱在节瓜上的世代发育历期最短，为19.3d，在苦瓜上的世代发育历期最长，为29.0d；世代存活率在黄瓜上最高，为92.85%，在苦瓜上最低，为53.08%；平均单雌产卵量在黄瓜上最多，为187.4粒，苦瓜上最少，为30.0粒；雌成虫寿命以在黄瓜上最长，为25.2d，在苦瓜上最短，为10.9d.B型烟粉虱在黄瓜、节瓜、苦瓜和丝瓜上的内禀增长率r(下标 m分别为0.1453、0.1429、0.0616和0.1055。

The life of stirrer has been prolonged to above 730 tank/single in industrial tests and production application.

通过与研制的搅拌头专用浇注料配合使用的工业性试验与实际推广应用，使搅拌头平均使用寿命提高到730次/支以上，达到了降低搅拌头维护量与脱硫成本的目的。

During its short 80 day lifespan, the average dust mite produces around 1000 allergenic waste particles!

在其短暂八○天寿命，平均尘螨过敏产生的废物约1000颗粒！

Coccinella septempunctata adult life span is longer, an average of 77 days, to adults and larvae prey aphids, spider mites, whitefly, corn borer, Helicoverpa armigera larvae and eggs and so on.

七星瓢虫成虫寿命长，平均77天，以成虫和幼虫捕食蚜虫、叶螨、白粉虱、玉米螟、棉铃虫等幼虫和卵。

The impacts on the diameter levels V and VI were indicated as abnormal increase of survivorship, negative values of mortality and decrease of mean life expectance whereas the impacts on the diameter levels III and IV were opposite to the levels V and VI. The survivorship curve of the Quercus variabilis population was fit with Deevey II.

静态生命表分析较好地反映出栓皮栎种群生长历史中的消长过程，清楚地透视出20年前坑木择伐对种群动态的长期影响，即径级V和VI（直径8~12 cm）存活株数异常增加、存活率提高、死亡数和死亡率出现负值以及平均期望寿命降低；而相应地对径级III 和IV带来与径级V 和VI相反的作用。

A mean strain or prestrain, as in Fig. 83, can under certain conditions reduce the subsequent fatigue life.

一个如图83所示的平均应变或预应变，在某种情况下，能够缩短以后的疲劳寿命。

The results have shown that 16 generations of the pest occurin a year in Beibei, Chongqing. At 15. 4℃-15. 6℃, 20. 1 ℃- 21. 6℃, 24. 4℃- 25. 8℃ and2 9. 6℃- 31. 5℃, theegg, nymph, protonymph and deutonymphstages last, on the ave...

成螨寿命8～42天，每头雌螨平均34.8粒；幼、若、成螨喜在叶底及叶缘分散为害，田间发生以5～6月、10～12月螨量大，对雨水冲刷及农药的抗性远比朱砂叶螨强，有逐步上升为桑园主要害螨之一的趋势。

The weight of larval and pupal feed on unspread leaves were higher than that of others, and the differences of the weight of larval and pupal during major development times were significant.

椰子心叶和成熟叶片上的成虫的性比分别为n：n＝1.27：1和n：n＝1.17：1，平均产卵量为143.3粒和161.93粒，成虫寿命分别为189.14 d和172.36 d，椰子心叶和成熟叶上的实验种群趋势指数分别为56.55和56.45。

Simulation results show that the average dissipated energy decreases by 29% in RESEE compared with directed diffusion, and the lifetime grew by 125% at the network size of 400. Residual energy distribution maps also prove the energy equilibrium characteristic of RESEE.

仿真结果表明：当节点数为400时，RESEE较定向扩散路由协议的节点平均能耗降低29%，网络寿命上延长125%，节点剩余能量分布曲线证明RESEE能更均衡地利用有限的能量。
