This paper introduces the working principle and blockdiagram of impulse magnet controlled discharge method that is used in the vacuity tester. The problems encountered in practice are discussed. The slight higher measuring result and incomplete discharge problem encountered in application are also analyzed. Finally, points for attention in future use are remarked.

In my silver high-heel shoes,I go to take part in a belated dinner,I go through a tall wood in a rush,On the trees there are fantastic tropical fruits and clocks streamed with egg white,The sweet fragrance of those fruits seduces me,I pick off a beautiful dragon fruit,But see many white worms lying in it when cutting it,I scream and throw it on the ground,Those worms creep to me and begin to grow,I creep onto the tree,They also creep towards the tree wiggling their bodies,I remove my cumbrous high-heel shoes and voile skirt creeping towards a high place,like an agile cheetah,But strangely my small bag oppressively cumbers me,It turns out that the bag is full of pumpkins, monkey dolls with large mouths, crystal bottles and silver coins,I give all of these a vicious discard towards the ground from the tree,But those worms open their big mouths and swallow all of them greedily,Becoming more obese and uglier,I desperately creep upwards,Suddenly the moon is not so far from me,I jump on it with ease,Suddenly finding that the moon is a porous spongy body with the fragrance of the oven-fresh French stick bread,It takes me to flow away from that tree full of worms,I want to light a cigarette but ignite the sponge on the moon,So I descend from the height,Falling down to a huge birds' nest,In an instant my whole body is wrapped by a slick and white egg shell,I find myself becoming a new embryo,Crouching in the warm and ropy liquid,The world presents a color of delicate light yellow,In a vacuum-like silence,I hear my contented voice,"What a perfect world"

我穿着银色的高跟鞋，去参加一场迟到的晚餐，我匆忙地穿过一片高大的树林，树上挂满了奇妙的热带水果和流淌着蛋清的时钟，那些水果甜美的芳香诱惑了我，我摘下一颗漂亮的火龙果，切开来却看见里面躺满了白色的蠕虫，我尖叫着将它们丢在地上，那些蠕虫向我爬来并且开始生长，我爬到树上，蠕虫们也扭动身体朝树上爬来，我脱下了牵绊着我的高跟鞋和纱裙，象只敏捷的猎豹朝高处爬去，只是我的小包奇怪而沉重地拖累了我，原来包里装满了南瓜、大嘴猴玩偶、水晶杯子和银币，我将所有这些朝树下狠狠丢去，那些蠕虫却张开大嘴贪婪地将所有这些吞食下去，并因此变得更加肥大和丑陋，我拼命努力地向上爬，突然月亮就在我不远处了，我轻而易举地跳了上去，恍然发现月亮竟是一个带着刚出炉法棍香味的多孔海绵体，它带我慢慢飘离了蠕虫的树林，我想要点燃一支香烟却不小心引燃了月亮上的海棉，于是我从高处坠落啊坠落，落入一个巨大的鸟巢，顷刻间全身被光滑洁白的蛋壳所包住，我发现自己成为了一个暂新的胚胎，蜷缩在温暖粘稠的液体中，世界呈现出微妙的淡黄色，在真空般的静寂中，我听见自己满足的声音："多完美的世界啊！"

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""
