Ageing rebels, second-year master's students with lacquered nails, broad-shouldered phonies in Norfolk jackets, snappers from Newsweek , all approached the cringing, little house where he had lived, or battened down, or holed up—you, general reader, can choose the word you please—ever since a great wave of fame had broken over him in 1953, two years after he happened to write a book called "The Catcher in the Rye".

老去的愤青，涂指甲的二年级硕士生，穿诺福克短外套的宽肩膀做作男，《新闻周刊》的摄影记者，都曾走近这幢隐匿的小房子；1953年，名望的巨浪压的塞林格喘不过气来，此后他就在这儿生活，或者说封闭、藏匿——读者朋友，随您怎样选择措辞。在此两年前，恰逢他写下了一本书，名为《麦田的守望者》。

Great progress has been made by taking the following technical improvement for the 2500 ton Hydropress: to replace thin oil with lithium grease in its lubricating system; to add four manual grease pumps; to lubricate the four griding parts of the movable beam and the six parts of the column plug sleeves.

Normally closed solenoid valve, coil power, the GATE VALVES armature under the action of electromagnetic force driving the first Vice-valve valve Seti, the main valve on the valve cup of fluid flow out through the Vice-valve, reducing the role of the main valve pressure on the valve cup, when the main valve valve to reduce pressure on the cup to a certain value, the armature driving the main valve valve cup, and use pressure Ershi main valve valve cup opening, medium flow.

常闭电磁阀，线圈通电后，衔铁在电磁力作用下先带动副阀阀塞提起，主阀阀杯上的流体经副阀流走，减少了作用在主阀阀杯上的压力，当主阀阀杯上的压力减少到一定值时，衔铁带动主阀阀杯，并利用压差而使主阀阀杯开启，介质流通。

Coil power, the electromagnetic suction is zero, the Deputy valve valve plug and the dynamic role of the iron core because of spring brought up, the Deputy valve is opened, the main valve on the valve cup of fluid flow out through the SAFETY VALVES Vice-valve, reducing the role of the cup on the valve in the main valve pressure, when the main valve to reduce pressure on the valve cup to a certain value, the use of pressure to push the main valve valve cup, the solenoid valve is opened, media circulation.

线圈断电时，电磁吸力为零，副阀阀塞和动铁芯由于弹簧作用向上提起，副阀打开，主阀阀杯上的流体经副阀流走，减少了作用在主阀阀杯上的压力，当主阀阀杯上的压力减少到一定值时，利用压差把主阀阀杯推起，电磁阀打开，介质流通。& 2 two-pass solenoid valve works &是由中国针型阀网提供的国际阀门新闻，译文仅供参考。另外，中国针型阀网还提供相关产品搜索：针型阀型号、针型阀价格、针型阀技术、针型阀新闻、针型阀生产商等。

The brass cylinders in front of the cylinder blocks are steam operated drain cocks which double up as pressure relief valves in case of water carry over.

在缸体战线黄铜汽缸蒸汽经营的双重排水旋塞，在水的情况下泄压阀了结转。

A theoretical analysis of local damage in a thin ductile tube hit by a flat-nosed missile laterally is developed to predict local failure due to plugging by the beam-on-foundation model. The effect of internal press was considered, and differential equations was obtained which can predict the ballistic speed of the missile which impact the tube filled with water. It can be solved by Runge-Kutta method.
