Boehmeriae were studied, and the results indicated that the zoospores of P. boehmeriae could be inactivated obviously by irradiating with 30W ultraviolet light 50cm away from the culture dishes tested and that 95% germination of zoospores could be restrained by 30W ultraviolet light treatment for 40sec.The mycelium growth from mycelium discs of P. boehmeriae were inhibited mostly by 30W ultraviolet light treatment for 20min. Afterwards, the inhibitive rates were decreased with the rise of the treatment time, which showed that the mycelium discs of P. boehmeriae had produced flexibility to ultraviolet rays after being irradiated by certain dosage of ultraviolet light.

研究了紫外光对苎麻疫霉生物学特性的影响，结果表明，30W的紫外灯管距培养皿50cm照射处理对苎麻疫霉的游动孢子具有明显杀灭作用，紫外光照射40sec可以抑制95%的游动孢子萌发；紫外光照射20min对菌丝块的菌丝生长的抑制率达最大，以后随着处理时间增加，抑制率却有降低的趋势，说明苎麻疫霉的菌丝块，经一定剂量紫外光照射后对紫外线产生了适应性。

It had the advantages of short operation time, safe operation, biological fixation, small trauma and so on, which could avoid the adverse reaction during infusion, the trouble of prosthetic repair after operation and much destruction of sclerotin.

非骨水泥型假体表面为多孔，植入人体后，依靠骨组织反应牛长能力，使骨与假体表面形成紧密地生物固定，其具有手术时间短，术中患者安全、假体固定为生物学固定、手术创伤小等优点，避免了骨水泥在注入过程中产生的不良反应以及术后假体返修所带来的取出麻烦、骨质破坏过多现象。

From the research result mentioned above, it was concluded that the selection of excellent single shoot tissue culture seedlings was an effective approach to guarantee fast growth and high yield of rattan plantation; the application of advance planting technique, such as controlling planting time, seedling number per group and spacing was very important for the purpose of minimizing unfavorable effect of rattan planting on upper trees, increasing cane yield and improving the level of economic gain; the determination of optimal harvest regime by adjusting the first harvest time, the lower limit of stem length for cutting as well as the harvest interval offered technical support to utilize resources reasonably and sufficiently and to enhance the economic benefit dramatically.

综合分析，通过组培快繁技术选择优质组培单芽藤是保证藤林速生丰产的有效途径；根据藤种的生物学特性，选择适宜的林地和上层林分，采取调控种植时间、丛栽株数和株行距等造林措施是减少棕榈藤间种对上层树种不利影响、有效增加原藤产量和提高林地增益水平的关键措施；而通过控制初始采收龄、起采茎长和采收间隔期，确定藤林最佳采收方式是促进资源充分利用、提高藤林的经济效益的有力保障。

According to our country condition of the superfine Merino sheep breeding, producing and marketing, and consider the future quality trend in a period of time, calculating to establish essential economics , biology and breeding technique parameter, and to establish 3 type and 6 production traits objectives.

根据我国超细型细毛羊的育种、生产和市场条件，并适当考虑未来一段时间的发展趋势，计算制定了育种目标所必需的经济学和生物学、育种技术参数，并制定了包括3类6个生产性状的育种目标。

As a gay man, I tend to believe the more we know about the complex interplay of biology and environment that shapes sexuality, the less time we will spend nourishing Old Testament anachronisms about sex.

作为一名同志，我倾向于，我们对塑造性向的生物学和环境复杂的相互作用了解的越多，我们怀有旧约中看待性的成见的时间就越短。

Classical radiobiology along the time domain: Historical review.

经典放射生物学在时间座标上的问题：历史回顾。

The results obtained revealed that:(1) the Pacific yellowfin has larger ring-radii as well as scale size than the Indian Yellowfin;(2) the specimens from the western Indian have larger value in scale size and ring-radii than those from eastern Indian;(3) there is a significant difference in the estimated growth curves between male and female for the Pacific specimens, but not for the Indian specimens; and (4) it is convinced that there are two yellowfin groups in the Indian Ocean, viz., one concentrates in the western Indian and the other densely distributes in the waters around Sunda Islands and Banda Sea; intermingling of these two groups is supposed to be occurred around 100°E in the season of northern summer.

3李氏现象在太平洋和印度洋都很显著。(4)年轮每年形成二次，时间为2～4月及8～10月。(5)有关成长的parameters如下：太平洋K=0.386 L=174.9 t0=0.05 东印度洋 K=0.278 L=212.7 t0=-0.19 中印度洋 K=0.290 L=215.6 t0=-0.01 西印度洋 K=0.349 L=191.1 t0=0.06 (6)由钓获率的分布、体长组成和其他生物学资料及以往之结果加以综合分析，显示印度洋的黄鳍鲔可分为东、西两个族羣，一为以班达海和小巽他羣岛附近海域为中心的东方羣，另一则以西部印度洋赤道流域为中心的西方羣。此两羣在100°E附近发生混合交流。当北半球的夏天时，此混合交流的现象较为显著。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
