This paper presents MMF of a five-phase induction motor with concentrated and full-pitch windings by means of fourier analysis and winding function , which indicates theoretically that the five-phase induction motor with concentrated and full-pitch windings can provide more electromagnetic torque and higher torque density than others.

本文运用傅里叶分析和绕组函数的方法，推导了集中整距绕组五相感应电动机的磁动势，得出集中整距绕组五相感应电机能更好地增加电机的电磁转矩、提高转矩密度。

In order to design optimum nozzle for air-air missile solid rocket motor, the mass model of solid rocket motor, the nozzle specifice impulse model of solid rocket motor and the objective function are established. Five different type of nozzles are choosen lor calculation: Conical, parabolidal,two different arcs,quadiatic polynominal and cubic polynominal.

以两种空-空导弹固体火箭发动机喷管作为算例，为此，建立固体火箭发动机的质量模型，喷管的质量比冲模型和目标函数模型，选择五种喷管扩散段内型面：锥形喷管，抛物线喷管，双圆弧喷管，二次多项式喷管和三次多项式喷管，进行优化设计，利用优化理论，成功地完成了五个设计变量的优化问题。

Michele then told me that the big aluminum pot with fifty-centimeter diameter and seventy-centimeter height I once saw in the garage of my in-laws is the main apparatus for passata making. They prepared four to five pots of it every time and hundreds kilos of tomato were used at least.

米奇这下子才告诉我，某次我在公公车库里看到一个直径约莫五十公分、高七十公分的大铝锅，就是每年制作番茄糊的主要工具，每次至少也煮个四五锅才肯罢休，几百公斤的番茄绝对跑不掉。

Exposure ages of bedrock samples taken from two nunataks in the Grove Mountains, interior East Antarctica, are studied by dating in situ produced cosmogenic 10Be and 26Al. The results indicate that the minimum exposure time of the five samples are all about 2Ma, much older than that of Last Glacial Maximum.

As a singlet curved lens is impossible to correct all the five primary aberrations regardless it is made of PIMs or NIMs, the primaxy-aberration-free lens systems composed of two thin lenses or two thick lenses based on the use of NIMs are intentionally presented.

由于只靠单块曲面透镜是无法同时消除全部五种初级像差的，因而我们接着研究了由负折射率介质构造的能同时消除全部五种初级单色像差的双薄透镜组合系统和双厚透镜组合系统。

These diets are like giving someone five five-dollar bills for their twenty-dollar bill.
