温度变化幅度

After comparison of 30 and 50℃ treatments, AQDS were added into 3 kinds of microorganism biocoenosis from Jiling, Tianjin and Sichuan paddy soil, and it showed that AQDS could accelerate the reduction of Fe 10%-288%, meanwhile, temperature could accelerate the reduction of Fe 6%-17%. In axenic culture treatment of 6 kinds of bacterial strains from Sichuan and Jiangxi paddy soil, the maximum accumulation amount of Fe reduction rate was constant, the maximum reaction rate and ferric reduction rate of ferric strain JX-a08 all increased as temperature rose, which showed that bacterial strain JX-a08 were suitable to 50℃.

在30和50℃培养温度下，来源于吉林、天津和四川的3种水稻土微生物群落添加AQDS可使Fe还原的反应速率常数增加10%~288%，而温度变化的增加幅度仅为6%~17%；对分离自四川和江西水稻土中的6株铁还原菌的纯培养试验发现，菌株JX-a08的Fe最大累积量、还原速率常数、最大反应速率及铁还原率均随培养温度的升高明显增加，表明菌株JX-a08更适于在50℃下生长。

Besides, the constraints such as the change rate of control variable are also considered.

其中包括：压气机喘振裕度限制，最高燃气温度限制，燃气发生器最高转速限制，动力涡轮最高转速限制，最大扭矩限制，燃烧富油熄火，贫油熄火限制等，另外还要考虑到工程实际中控制作用量的变化速率和变化幅度限制等约束条件。

Therefore, the possibility that the film flow was in onflow state was very low under the fisher swing frequency even though the swing affixation force acted on the film. In falling film absorption process, the velocity, temperature and concentration distribution of the liquid film was symmetry on the swing plane basically.

降膜吸收过程中，液体的速度、温度和浓度分布基本上是关于摇摆平面对称分布；速度场、温度场和浓度场的变化周期近似等于摇摆周期；摇摆幅度和摇摆频率直接影响降膜吸收的效果，摇摆频率越低或幅度越大，吸收效果越差。

随辐照时闻的增加，温度的升高，其温度涨落的幅度基本保持不变，这一持性是由不锈钢的热学参数如热传导率、热扩散率随温度变化的规律所决定的。

Here we show that the phase of the annual cycle of surface temperature over extratropical land shifted towards earlier seasons by 1.7 days between 1954 and 2007; this change is highly anomalous with respect to earlier variations, which we interpret as being indicative of the natural range.

假设这一温度记录的前一部分是由自然变化所主导的，那么最近的趋势似乎高度异常：陆地上的温度向早先的季节有1.7天的偏移，而变化周期的幅度（即夏季和冬季之间的温差）在这一时期降低了。

Meanwhile the mutative trend of nitrogen PL intensity is fit to that of isothermal annealing treatment with increasing annealing time, even though the variation is small.

当退火温度为1573K时，随着退火时间的延长，PL结果与等时退火的变化趋势一致，但变化幅度不大。

Study result suggest: The change of stock in RFCCU directly affect gasoline content. Gasoline content can be reduced through increasing the equilibrium activity of catalyst, controlling reaction level, increasing recirculating rate of gasoline and stability of gasoline level. Conclusions drawn from experiment is that optimization of operating condition has great effect on lowering olefine content of gasoline which can be reduced from 60% to 50%.Reducing reaction temperature is useful for lowering olefine content of gasoline, when the reaction temperature is raised, thermal cracking rate is higher than catalytic cracking rate, so that olefine content is increased. Raising catalyst-to-oil ratio is good for lowering olefine content. With conversion rate increased, the yield of LPG and coke is raised, the yield of gasoline is increased firstly and then decreased slightly, hydrogen transfer index is increased, so the olefine content is decreased.

研究结果表明：催化裂化装置的原料的变化直接影响到催化汽油的烯烃含量；可以通过优化催化装置的操作条件来降低催化汽油中的烯烃含量，其中通过提高催化剂平衡活性、控制反应深度、增加汽油回炼量、汽油深度稳定可以降低催化汽油烯烃含量，优化工艺条件对降低催化汽油烯烃含量有较大作用，汽油烯烃含量由60％降至50％左右；降低反应温度有利于降低催化汽油的烯烃含量，当反应温度的提高，热裂化反应速度提高的幅度大于催化裂化反应速度提高的幅度，汽油烯烃含量增加；剂油比的提高有利于降低催化汽油的烯烃含量，转化率提高，液化气产率提高，汽油收率先增加后略有下降，焦炭产率增加，氢转移反应指数提高，汽油烯烃含量下降；反应时间对产品分布及汽油烯烃含量有影响，增加提升管反应时间，液化汽、汽油产率提高，干气和焦炭产率增加。

As measurement results, of the four parameters involved, wind speed and precipitation varied significantly during the monitoring period, while temperature and pH value of rain water changed unapparently.

量测结果发现，测量期间风速、雨量等参数的变化幅度较大，温度及雨水pH值变化趋势则较不明显，但未足以在这些参数与水中氡浓度增加间建立显著的关系。

Among the slope instability types, thaw slumping is the most hazardous to engineering projects. The ground temperature data of long-term monitoring in the typical thaw slumping indicates that average ground temperature increases and annual fluctuation of ground temperature are reducing under the thaw slumping. The reason is that the heat flux entering permafrost reduces.

针对典型热融滑塌进行的温度监测资料表明，在滑塌的影响下，其下多年冻土地温年变化幅度趋小而年平均地温升高，导致产生这一现象的原因在于每年进入多年冻土的冷能有所降低。
