Simultaneously, the safety air bag made of the fabric has good flexibility, low ventingquality and high size stability.
同时该织物制成的安全气囊具有良好的柔软度，较低的通气度，高的尺寸稳定性。

Compared with the control, the vacuum package or adding deoxidant package with materials of low ventingquality can constrain the accelerating speed of PV and AV, and delay rancidity.
采用低透气性的包装材料进行真空包装或添加脱氧剂包装，可明显抑制过氧化值和酸价的增加速度，延缓酸败。

High-quality buret have a venting-mechanism with which they can be very easily refilled with the exact volume for which the buret is calibrated.
