Gyrotron has the superiorities , high peak power and high average power . so gyrotron is vastly applied in many areas , such as plasma heating , controlled thermonuclear fusion ( ctf ) , radar , communication , electron countermeasure 回旋管具有在毫米、亚毫米波段其他器件无可比拟的高峰值功率、高平均功率的优越性,因此在等离子体加热、受控热核聚变、雷达、通信及电子对抗等方面都有着广阔的应用前景。
In 2003 , peak activity is expected to occur on 18 november . because meteoroids are unevenly distributed along their paths around the sun and gravitational pull from nearby planets may perturb their orbits , the time of peak activity and the number of meteors cannot be predicted exactly 由于流星体是不均匀地分布在环绕太阳的轨迹上，往往受行星引力的影响而令轨道产生变化，因此要准确地预测流星雨高峰值出现的时间及流星数目是很困难的。
Cassava root is used for carbohydrate source in tropical region . quality of cassava starch is variable and affected by many factors . an attempt was made to evaluate the effect of peeling , washing and drying on starch purity and starch paste viscosity . paste viscosity were based on results of rapid visco analysis ( rva ) . the results of this study revealed that : peeling , washing and drying temperature significantly affected cassava starch purity and starch paste viscosity . the starch from unpeeling root had a dullness color , but had higher peak viscosity , trough , final viscosity , breakdown and setback than that of starch from peeling root . more washing not only increased starch purity , but also improved starch past characteristics , such as peak viscosity , trough , final viscosity , setback and pasting temperature . different drying temperature had no effect on starch whiteness . starch purity had a little increase with drying temperature increasing . in general trend , starch dried at higher temperature had higher peak viscosity , trough , breakdown , final viscosity and higher setback 木薯在热带地区是碳水化合物的主要来源.木薯淀粉的品质受许多因素的影响.本项研究着重探讨淀粉提取过程中,削皮、水洗、干燥温度对淀粉纯度、白度和淀粉糊化粘度的影响.结果表明,未削皮的淀粉样品色发灰,但具有比削皮处理高的峰值粘度、 95最后粘度、 50时粘度、峰值降和持久性.增加水洗次数,不但能增加淀粉纯度,还可提高淀粉高峰值粘度、 95最后粘度、 50时粘度、持久性和糊化温度.不同干燥温度对淀粉白度无影响,但淀粉纯度随干燥温度的提高而稍稍增加.通常高的干燥温度有高的峰值粘度、 95最后粘度、峰值降、 50时粘度和持久性
After analyzed the basic principle of optimized noise reduction on tyre pattern , summarized three approaches to noise reduction . the first is trying to reduce size of single block or socket to reduce noise amplitude on time domain , the second is to adjust stripes sorting order and their interlace value to avoid noise - made by every single block - peak values on time domain overlayed and the last is to adjust ratio of blocks and sockets , ratio of stripe interval and stripe sorting order to avoid noise periodical distribution and abnormal high peak values in some frequency strip 论文第四章分析了轮胎花纹优化降噪的基本原理，总结出三条降噪途径：在允许范围内尽量减小单个块或槽的大小、刻刀槽软化花纹块来减小噪声时域波幅度；调整节距排列顺序、花纹条之间的错位值，使各发声单元发出的声压时域波形的同向峰值错开，避免同向峰值叠加；调整花纹块和槽比例、节距比例、节距排列顺序，尽量避免周期性分布，使轮胎所发出的噪声趋于白噪化，避免某些频段的异常高峰值。
So its naissance brings a lot of hope and promotion to application and deploitation of milimeter and submilimeter - wave . because of gyrotron , s superiority of high peak power and average power among many known milimeter and submilimeter - wave gyrodevices , it has been paid much respect in the world for application in many areas such as plasma heating , rf accelerator , millimeter radar , dew and so on 由于回旋管具有在毫米、亚毫米波段其它器件无可比拟的高峰值功率、高平均功率的优越性,因此在受控热核聚变等离子体的回旋管加热( ecrh ) 、电子高能rf加速、雷达系统、通信系统以及定向武器( dew )等方面都有着广阔的应用前景。
