极端温度
相关语句
  extreme temperature
    The space environment refers to an environment far away from the earth's surface and different in many respects from the surface of the earth,where animal cells will be influenced by all kinds of space factors,including mainly space radiation,extreme temperature,high vacuum,micro-magnetic field and the special environment in spacecrafts,namely,that of microgravity.
    空间环境是指远离地球表面的宇宙环境,它与地球表面环境有所不同,处于其中的动物细胞可能受到各种影响。 空间环境中的主要因素包括空间辐射、极端温度、高真空、微磁场以及搭载动物细胞的航天器中的特殊环境——微重力环境。

The recurrence and intensity of extreme temperature drops during the growing seasons of the past six centuries were reconstructed.
      
In particular, the extreme temperature range on Mercury may result in latitudinal variations in the size distribution of npFe0, and therefore the spectral properties of the soil.
      
The possibility of using this material for the manufacture of thermomechanical couplings intended for the design of extra reliable thermomechanical joints operating under extreme temperature conditions is considered.
      
To achieve a suitable resolution, with this particularly exacting high-temperature application, a short 5 m capillary column of extreme temperature stability has been used.
      
A method is developed that enables one to model extreme temperature regimes for heterogeneous reactions, to study the mechanisms of structure formation at a microscopic level, and to perform micrography of the process of interaction.

The influence of the durations of extreme temperatures on the mortality of California red scale was tested by use of the conbinations of three extre- mes of temperatures,namely,-2,+5 and +45℃;by seven durations, namely,0,0.5,1,2,4,6 and 8 hours.Results indicated that most of the mortalities at the low constant temperature(+10℃)were smaller than those at extremes of low temperatures(-2 or+5℃)with O-hour dura- tion;but no difference was found for the 3rd instar or the 2nd moult female. However,there were few significant...

The influence of the durations of extreme temperatures on the mortality of California red scale was tested by use of the conbinations of three extre- mes of temperatures,namely,-2,+5 and +45℃;by seven durations, namely,0,0.5,1,2,4,6 and 8 hours.Results indicated that most of the mortalities at the low constant temperature(+10℃)were smaller than those at extremes of low temperatures(-2 or+5℃)with O-hour dura- tion;but no difference was found for the 3rd instar or the 2nd moult female. However,there were few significant differences in the mortality between the constant temperature of 25℃ and the extreme temperature of 45℃ with the O-hour duration;the only big difference was for the 1 st moult red scale and the 2nd moult male red scale. Results also indicated that subjecting the 3rd instar red scale to differ- ent durations of high temperature(+45℃)did not affect the reproduction of the surviving adult female scales.

测定了极端温度(-2,+5及+45℃)持续时间(0至8小时)对红圆蚧 Aonidiella aura-ntii(Mask.)死亡率的影响,同时观察了红圆蚧在+10℃和+25℃恒温下的死亡率.在低温实验中,除了3龄雌虫及第二脱皮阶段雄虫外,红圆蚧大多数龄期、虫期在极端温度-2或+5℃的死亡率明显高于+10℃恒温时的死亡率。在高温实验中,红圆蚧在极端温度+45℃与在+25℃恒温下的死亡率相似;+45℃高温仅对第一脱皮阶段红圆蚧(不分雌雄)及第二脱皮阶段雄虫死亡率有明显影响。经历过+45℃高温处理的3龄雌虫,如能存活下来,成虫生殖能力与在+25℃恒温下生活的虫子相比没有差异。

A novel multifactorial evaluation method were developed on the basis of rubber trees byemploying environment indexes closely related to the growth, development and production ofthe crop,such as annual mean temperature,extreme temperture,precipitation and typhoons. The Bayes’decision rule in the probability theory were employed to computerize the condi-tional probability,namely posterior probability,occurring in different status of crop produc-tion under a consideration of a group of environment indexes;This...

The Bayes’decision rule in the probability theory were employed to computerize the condi-tional probability,namely posterior probability,occurring in different status of crop produc-tion under a consideration of a group of environment indexes;This probability was used as ameasurement to study the ecological adaptation of tropical crops.Results show that thiscomprehensive multi一factorial evaluation method coincided with the field investigation.

以橡胶为例,选取了与其生长、发育和产量形成关系密切的年均温度、极端温度、年降水量和台风影响次数作为环境指标,采用概率论中的贝叶斯准则计算了在实现一组环境因子下,其产量不同等级状态出现的条件概率,即后验概率,以此作为研究热带作物生态适应性的量度。结果表明,效果良好,与实际较为吻合,不失为一种良好的多因子综合评价方法

The production of active oxidative species (AOS) in plant cells is an initial response to biotic stress (bacterial, fungal and viral infection) and abiotic stress (such as irradiation, herbicides, wounding, ozone, sulfate dioxide, extreme temperatures and water stress, etc.). Molecular modification of oxidative metabolism in transgenic plants has become a new direction for providing tolerance to biotic and abiotic stress in recent years. In this article, the progress in genetic engineering of anti-oxidative...

The production of active oxidative species (AOS) in plant cells is an initial response to biotic stress (bacterial, fungal and viral infection) and abiotic stress (such as irradiation, herbicides, wounding, ozone, sulfate dioxide, extreme temperatures and water stress, etc.). Molecular modification of oxidative metabolism in transgenic plants has become a new direction for providing tolerance to biotic and abiotic stress in recent years. In this article, the progress in genetic engineering of anti-oxidative stress is reviewed. The main emphasis is concentrated on the stress tolerance of transgenic plants overexpresssing superoxide dismutase (SOD), glutathione reductase (GR) or glucose oxidase (GO) gene. In addition, the strategy for further development of stress tolerance via genetic manipulation is discussed as well.

生物逆境如细菌、真菌、病毒和非生物逆境如辐射、除草剂、创伤、臭氧、二氧化硫、极端温度及水份胁迫等引起植物的初始反应都是活性氧类的增加,利用分子生物学手段,对植物的氧化代谢进行修饰,提高植物抗氧化胁迫的能力,进而抗生物和非生物逆境已成为近年来植物抗性研究的一个新的方向。本文总结了近年来国际上抗氧化逆境基因工程研究所取得的进展,包括超氧物歧化酶(SOD)、谷胱甘肽还原酶、葡萄糖氧化酶转基因植物对环境胁迫耐性的变化。文中对植物抗氧化逆境基因工程的今后发展亦作了讨论
