Under the same wall heat condition, with the increase of momentum correction coefficient, viscosity loss of the nozzle increases, but thrust and specific impulse decrease.
在同等壁面热条件下，随着动量调节系数的增加，喷管粘性损失增大，喷管的推力和比冲都将下降；
Not to nozzle parts inflatable will not sweat, oil, drugs (alcohol) touched nozzle, from the ink composition, viscosity changes, resulting in ink solidification obstruction.
不要向喷嘴部位吹气、不要将汗、油、药品(酒精)等沾到喷嘴上，引起墨水的成分、黏度的变化，造成墨水凝固阻塞。
The Pressure Type, the small nozzle can be used in a large field, from low to high viscosity.
压送式型号，喷嘴口径小也能在低粘度到高粘度比较广的范围内使用。
