Crack side of apical towards the left from buttock or on the right side of equalize is horizontal, make one perpendicular bisector from qia ji apogee next, will coxal cent is 4 quadrant, quadrant goes up outside its and escape an internal angle ( connect a line to big rotor from the thorn on qia hind ) it is inject area namely
從臀裂頂點向左側或右側劃一水平線，然後從髂嵴最高點作一垂直平分線，將臀部分為四個象限，其外上象限並避開內角（從髂後上棘至大轉子連線）即為注射區。 -

答： "十"字法：從臀裂頂點向左側或右側劃一水平線，然後從髂嵴最高點作一垂直平分線，將臀部分為四個象限，其外上象限並避開內角（從髂後上棘至大轉子連線）即為注射區。 -
The results of the experiments have showed that the vibration of the head and the buttock mainly take place in the frequency of 0. 5 ~ 20hz, the vibration acceleration of the passenger ' s head on the high - level sleeper bus at highway does not exceed 1. 20 m / s2, the buttock ' s vibration acceleration is not more than 1. 00m / s2, however the acceleration of the legs " vibration is less than 0. 50m / s2. the vibration experiments of trains were done on the hard and soft berths in the mountain diverged line and the plain main railway, the data showed that the vibration of the passenger ' s head and pelvis mainly took place in the frequency of 0. 5 - 15hz, under this range, the acceleration of head ' s vibration do n ' t exceed 0. 80m / s2, the but tock ' s vibration acceleration is not more than 0. 40m / s, the legs " vibration acceleration is less than 0. 30m / s
數據分析表明，頭部和臀部振動主要發生在0 . 5hz 20hz ，高檔公路臥鋪客車在高速公路上，頭部振動加速度值一般不超過1 . 20m s ~ 2 ，臀部振動加速度值一般在1 . 00m s ~ 2以下，而腿部振動加速度值一般在0 . 50m s ~ 2以下；鐵路臥鋪客車臥姿乘客振動試驗分別在山區支線和平原干線上運行的硬臥及軟臥臥鋪進行，數據分析表明，頭部和臀部振動也主要發生在0 . 5 15hz ；平原干線的鐵路軟臥，頭部振動加速度不超過0 . 80m s ~ 2 ，臀部振動加速度值不超過0 . 40m s ~ 2 ，而腿部振動加速度值則在0 . 30m s ~ 2以下。
