The principal of buffer is described as follows.At impulsing down,the piston moves down and vacates the annular space.The pressure in respiratory cavity decreases to a certain level and the traveling valve opens.At that time,the liquids enter into traveling valve and cavity and the plunger is impulsed upward to carry out the gentle transient at the sudden change.When the upward impulsing begins,the respiratory cavity is subjected to pressure and the traveling valve closes.During the gradual pressure rising,the liquids in respiratory cavity effuse from the upper ventage and the sudden change of force-summing direction of plunger is relieved relying on the resistance of ventage.

其原理大致是：下冲程时，活塞向下运动，让出环形空间的体积，呼吸腔内压力下降，下降到一定水平后，游动阀打开，此时，游动阀和小孔同时进液，使柱塞在从上死点处突然改变方向向上运动时得到缓冲，实现了柔和过渡；当上冲程开始时，呼吸腔受压，游动阀关闭，在压力逐渐上升的过程中，呼吸腔内的液体从上部的小孔流出，并依靠小孔的阻力使柱塞受力突然换向得到缓冲。

Dalian coldly has suddenly gotten down, suddenly drops, unexpected,likely winter in suddenly puts in the ice-cold foot the boiling hotfoot basin, bone-chilling cold, stabbing pain ~ The wind careless is blowing..

大连突然就冷下来了，骤然下降，猝不及防，就象冬天里突然把冰冷的脚伸进滚烫的洗脚盆，凛冽，刺痛~风忽忽的刮着。。

Ten minutes later, BP dropped to 96/54 mmHg and HR dropped from 67 to 31 during one minute. Atropine was prepared for rescue. Suddenly, EKG showed asystole and patient lost his consciousness. Atropine 0.8 mg, iv, was immediately administrated and face mask ventilation was also performed.

十分钟后，血压突然掉至96/54毫米汞柱，心律也逐渐变成心搏徐缓(在一分钟左右的时间心跳从每分钟67下降至31下)﹔在准备atropine的同时，突然间心跳停止并且病人失去意识，atropine 0.8mg马上给予并且使用人工面罩通气。

When a sudden power failure or accident or normal pump stops when the pump stops, the valve inlet water velocity to reduce stress Agency, the valve plate also fall, when its velocity is zero (that is, inlet flow rate is zero Department), large valve plate because of its own gravity and rapidly turn off (time 3s ~ 5s), the majority of water to prevent backflow, when the valve before and after the formation of a water pressure, water stress, on the one hand through the small valve at the bottom of the three slot for pressure relief vent pressure. 4 water stress from the bypass tube into the cavity patch up the control room (this process for the suction pressure chamber that can effectively absorb the energy of water), when water stress on cavity than inferior vena cava, the pressure of water promote the diaphragm down mobile , the current cavity pressure of water being squeezed out all the small valve plate slowly drop back to standby status, the process time to ease closure adjustable (3s ~ 150s), then the valve has been fully closed, watertight.

当突然停电或事故停泵或正常停泵时，阀门进水口处压力水流速降低，大阀板也随之下降，当其流速为零时，大阀板由于自身重力而迅速关闭（时间3s～5s），可防止大部分水倒流，此时阀门前后形成一种水压差，压力水一方面通过小阀板底部的三条泄压槽进行泄压。4）压力水从旁通管进入膜片控制室上腔（此过程为吸压腔，能有效吸收一部分水能量），当上腔压力水大于下腔时，压力水推动膜片往下移动，当下腔压力水全部被挤出来时，小阀板缓缓下降，恢复到待机状态，此过程中缓闭时间可调节（3s～150s），届时阀板已全部关闭，滴水不漏。

It is also easy to prevent. Always mark your rope's midpoint, enabling you to keep the rope centered through the anchor; tie bulky knots in both ends of the rope that will jam in your rappel device; and use a backup such as a prusik on the rope clipped to your harness with a locker.

我们要防范可能的垂降坠落意外，首先第一点是要将绳子的中间点做适当的标记，确保在使用双绳垂降时，绳子的中间点能够正好在下降Anchor的中间；另外，垂降时在绳尾打结也是所有攀岩书籍中耳提面命的防范措施，他可以让你在绳子突然不够长时，卡住你的下降器，避免你失控坠落；还有一个方法是多利用普鲁士结等自动锁死系统，让你的垂降安全多一份保障。

台北马偕医院小儿过敏免疫科徐世达指出，过去多认为季节交替时，气温突然下降，才会引发过敏反应，但是最近气温飙升，过敏门诊病患也随之激增二成。

The pulsing rate is manipulated so as to repeatably increase the pulsing rate over a time span to an intermediate pulsing rate and abruptly drop the pulsing rate to a decreased rate between the intermediate pulsing rate and a previous rate, until a predetermined final pulsing rate is reached.

脉冲率受到控制，反复使脉冲率在一段时间内增大到一个中间脉冲率和使脉冲率突然下降到一个在中间脉冲率和一个先前脉冲率之间的减小的脉冲率，直至达到预定的最终脉冲率。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
