Hangzhou cuiqinzhai moslem food co . , ltd . has its history of nearly one hundred years . in emperor guangxu s reign during the qing dynasty , a moslem man from beijing with his wife opened a food workshop in hagnzhou , named cuiqinzhai and dealing with moslem snack 杭州翠沁斋清真食品有限公司,已有百余年历史的中华老字号企业,相传在清光绪年间,一位来自京城的回民,带着他的妻子在杭州城内开了一个名叫“翠沁斋”的茶糖作坊,专营清真京式茶食糕点。
This thesis analyse the linear theory of gyro - twt with spiral corrugated waveguide and two - beam coaxial gyrotron . first of all , base on the theory of coupled - wave , the dispersion equation and coupling condition of spiral corrugated waveguide is realized by applying the method of impedance perturbation 首先,在耦合波理论基础上运用阻抗微扰法分析了内开槽螺纹波导的冷腔色散特性,通过数值运算作出了冷腔色散曲线同时用三维粒子模拟软件进行了相应的冷腔分析。
If , the leader of an unit , had this kind is inert , this unit has new color impossibly again , meet twice bring shame on , cannot see new thing , so that the flower left to also be not heard inside the wall , go out sweet come , drew the bee he diecai outside to be one of jing when these flowers only 假如，一个单位的领导，有了这种惰性，这个单位就不可能再有新的气色，就会两眼抹黑，看不到新事物，以至于墙内开了花也闻不出香来，只有当这些花引来了外面的蜂和蝶才为之一惊。
Thus the theory study based on experimental result are as the following : 1 . the coaxial inner slotted structure waveguide is simulated and analyzed numerically , the change of the work frequency and space between work modes of coaxial structure is studied with the inner slotted . the parameters like the number and the depth of the inner slotted are optimized 本文以此为切入点展开了以下几个方面的研究: 1 .通过仿真和数值分析,研究了同轴波导加内开槽后模式之间间隔和工作频率前后的变化情况;通过改变槽的个数和深度,得到同轴波导内开槽的优化参数。
It is found that the work frequency is decreased but the space between work modes is enlarged a little with the inner slotted in rbwo with coaxial structure . 2 . rbwo with partial inner slotted structure is designed and simulated , it is found that the work frequency is decreased and the space among modes is enlarged well with the inner slotted in rbwo with partial structure 2 .对偏心返波管进行了仿真,研究了偏心返波管加内开槽后模式之间间隔和工作频率的变化情况;发现加槽后偏心返波管的工作频率有所降低,偏心返波管模式间隔增大较为明显。
In emperor guangxu s reign during the qing dynasty , a moslem man from beijing with his wife opened a food workshop in hagnzhou , named cuiqinzhai and dealing with moslem snack . while he made the moslem food , the whole street could smell the sweet and people who tasted the food made by him all gave a good appraisal . so cuiqinzhai snack became famous all over hangzhou city 杭州翠沁斋清真食品有限公司,已有百年的历史,相传在清光绪年间,一位来自京城的回民,带着他的妻子在杭州城内开了一个名叫“翠沁斋”的茶糖作坊,专营清真京式茶食糕点。每到开炉时,常常香满全街,而品尝过这里糕点的人,都感到色香味俱全。
A linear theory of rbwo with inner - slot coaxial structure is analyzed detailedly , and the equation of dispersive relation is deduced and computered numerically . 4 . particle simulation is used in rbwo respective with coaxial and partial structure . in the simulation , the output parameters of rbwo such as phasespace , contour , vector , voltage , current , output power , interaction efficiency and microwave radiation 4 .对同轴和偏心返波管分别进行了粒子模拟,通过改变电压、电流、电子注位置、磁场等参数来观察返波管加了内开槽前后相位空间、等位线、矢量、电压、电流、输出功率、工作频率的变化。
Economically , mongolia is not highly developed , but the ulaanbaatar center is nonetheless becoming self - reliant . the local disciples have learned to cook vegetarian cuisine and opened a vegetarian restaurant at the center , preparing dishes with homemade gluten , noodles and bean curd . thus , the center is filled with an atmosphere of warmth and prosperity 蒙古的经济虽不很发达，小中心却能朝向自立自主发展，他们不但学习煮素菜，在小中心内开了一家素食餐馆，并且学习如何自制面筋面条豆腐等食品，让小中心充满温馨与欣欣向荣的气氛。
