To eliminate static electricity commonly used methods are: an increase in the use of humidity-left to set paper hanging in the laboratory and workshop of relative humidity, moisture content of the paper hnproving; paper in advance to the machine, to fit the business card printing and membership card-making workshop of temperature and humidity.

消除静电常用的方法有:利用加湿器增加吊晾纸张的室内和车间的相对湿度,以提高纸张的含水量;提前将纸张放到机器旁,以适应制卡和会员卡制作车间的温、湿度。

There are abundant rainfalls here,with cool summer and warm winter.

The results were as follows: with the shortened distance from the forest edge, photosynthetic rate of rice quadrats were gradually reduced; while the temperature, relative humidity and CO2 concentration in rice population did not change significantly; rice yield declined in a row, mainly because of a significant decreased panicles per unit area.

结果表明,随着与林缘距离减小,样方水稻的光合速率逐渐降低,而水稻群体内的温度、相对湿度和CO2浓度的变化不明显;水稻产量连续下降,其主要原因是单位面积穗数的大幅度降低;而不同林缘距离样方水稻的千粒重和结实率变化甚微。

The effect and its mechanism of temperature during grain filling on rice quality were investigated by using 4 eary-indica rice cultivars with different quality and amylose content. The plants at filling stage were transferred into two phytotrons (Model PGV-36, CONVIRON, Canada), which were set two mean daily air temperatures, i.e. 22℃, optimum temperature regime and 32℃, designed as high temperature regime. The differences in quality properties and starch characteristics of rice between two temperature regimes were determined, and effects of temperature at grain-filling stage on starch biosynthesis in developing rice grains were also analyzed.

本研究以田间异季栽培试验为基础,利用人工气候箱(PGV-36型,CONVIRON)设高温(日均温度32℃)和适温(日均温度22℃)两个典型温度处理,在日温差、光照、相对湿度等因素完全一致的条件下,系统地研究了水稻灌浆结实期不同温度对早籼稻米淀粉的DSC热力学特性、RVA粘滞性、晶体结构、淀粉链长分布等理化指标的影响及其品种类型间的差异,并分析了水稻籽粒淀粉合成代谢过程中几个关键酶的温度效应特征及其与稻米淀粉合成和积累的关系。

Infrared transmittance was also tested in the article when smoke composition granularity, density of powder charge , relative humidity ,mass of the raw materials per unit volume were different in formula.

文中还测试了发烟剂在原材料的粒度、装药密度、大气相对湿度、单位体积用药量不同时的红外透过率。

According to ecological observation and analysis of Ericerus pela living in Emei, Zhaotong and Kunming, the environments of which encourage rates of high excreted waxes are not suitable growth areas for Ericerus pela. The main ecological characteristics for suitable growth areas of Ericerus pela are described as follows: annual average temperature 11-16℃, light 1900-2500 h/a, rain fall 800-1200 mm and annual relative humidity 65%-75%.

根据在峨嵋、昭通、昆明等地对白蜡虫的生态适应性观察和分析,白蜡虫泌蜡高的环境不是白蜡虫适生区域,白蜡虫适生区域主要生态指标为:年均温11~16℃,降雨量800~1200mm/年,年相对湿度65%~75%,年光照时数为1900~

Quasi-natural air delivery pattern may be the most favorable dynamic pattern. So a subjective questionnaire research on t...

本文对大连夏季室外凉亭下的环境特征和人的热舒适性做了主观问卷调查研究,通过对428个有效样本的研究与分析,回归得到了人体热舒适投票值TCV与人体平均温度和周围空气温度之间的关系式,在满足该式的条件下,人体平均温度在35.7~36.5℃之间,空气温度在25.5~30.4℃之间变化,且空气相对湿度保持在40%~60%,风速在0~1.5m/s之间波动,人体都可以达到热舒适状态,并发现人们在室外自然环境下往往感觉吹风不足,这点正好与传统空调中人们易产生吹风感的抱怨相反,从而为适当提高送风速度与温度,节约空调能耗奠定了基础。

The results showed that the temperature had the tendency of increasing in these regions; the rainfall, raining days and relative humidity had no significant changes; the index of K was over 0 in most areas, that is, the possibility of wheat scab occurrence will be increased year by year.

结果表明,冀京津区域气温有增加趋势,有利于小麦赤霉病的发生流行;冀京津区域降雨量、降雨日数、相对湿度等气象因子未表现出明显的变化;大部分地区K指数大于0,即春季小麦赤霉病发生流行的可能性逐年加大。

The results showed that condensation temperature and condensation pressure increased with increasing inlet air wet-bulb temperature.

对影响板式蒸发式冷凝器热工性能的主要因素——空气的湿球温度、冷凝温度、相对湿度做了实验研究。

Compressor power consumption was greatly affected by inlet air relative humidity and wet-bulb temperature.

结果显示:冷凝温度和冷凝压力均随着入口空气湿球温度的升高而升高;入口空气相对湿度对压缩机功耗的影响与湿球温度对压缩机功耗的影响均比较大;对基于同一压缩系统的实验比较表明,在冷凝温度为38℃时,板式蒸发式冷凝器的热流密度比管式蒸发式冷凝器平均大30.5%;且在相同的冷凝温度下,入口空气湿球温度越低,板式蒸发式冷凝器的热流密度比管式蒸发式冷凝器大得越多。
