A analysis of these effect to the pattern is presented. in the mean time, the method of correcting the phase errors is given by shortening or lengthening the section of sinuous feed line between couplers from the normal value. 6. the reflection characteristic of a serpentine is analyzed where the coupler is replaced by the equivalent of two ports loss network
提出了用有耗二埠網路來等效波導耦合器的方法，對由耦合器、饋電波導和波導彎頭級聯的慢波線系統的駐波特性進行了分析計算，針對慢波線在設計測射頻率上大反射問題，討論了多種解決辦法。 -
This paper uses the program to calculate the dynamics performance of small slack coupler that designed by qiqiha ' er vehicle ( grounp ) company. by compared maximum coupler force and maximum acceleration of car body with common slack coupler at condition of train starting, braking, emergency braking and releasing, we verified that small slack coupler is better than common slack coupler in dynamics performance. this paper also calculated the train dynamics performance parameter with different buffer and braking system, running in different line and using different operating method
本文利用列車縱向動力學模擬程序，計算了齊齊哈爾車輛（集團）公司研製的13號小間隙防脫車鉤的縱向動力學性能，通過比較各個車鉤間隙下列車最大縱向車鉤力和列車最大加速度的數值，得出小間隙車鉤在列車啟動工況、常用制動工況、緊急制動工況、緩解工況的縱向動力學性能都較原有車鉤性能優異的結論。 -
Five cell circuits are designed, fabricated and tested, including 5. 625 degree and 45 degree using loaded - line phase shifter, 90 degree using 3db branch - line coupler phase shifter, 90 degree and 180 degree using switched - line with loaded - line phase shifter. according to the testing result of cell circuits, and requirement of ku - band six - bit digital phase shifter, the scheme for ku - band six - bit digital phase shifter is chosen
本文對5 . 625度和45度相移位採用主線加載的加載線形式，對90度相移位採用3db支線耦合器形式和加載式的開關線形式，對180度相移位採用加載式的開關線形式，分別進行了五個單元電路的設計、製作與測試。 -
The phase shifter circuit consists of five digital bits corresponding to differential phase shifts of 180, 90, 45, 22. 5 and 11. 25 cascaded in a linear arrangement. the three lower phase shift circuits are of loaded - line type, in which the 11. 25 phase shift bit use a single loaded - line configuration. the 90 and 180 phase shift bits are of reflection type, using lange coupler to realize the separation between the incident and reflection signals
移相器電路由五位移相電路級聯而成， 11 . 25 、 22 . 5和45移相電路為加載線型，其中11 . 25採用了單加載線形式； 90和180為反射型移相電路，使用蘭格耦合器實現輸入、輸出信號的隔離。
