When we told them how we plac'd our selves, and the Horses in the Middle, they blam'd us exceedingly, and told us it was fifty to one but we had been all destroy'd; for it was the Sight of the Horses which made the Wolves so furious, Seeing their Prey; and that at other Times they are really afraid of a Gun; but the being excessive Hungry, and raging on that Account, the Eagerness to come at the Horses had made them sensless of Danger; and that if we had not by the continu'd Fire, and at last by the Stratagem of the Train of Powder, master'd them, it had been great Odds but that we had been torn to Pieces; whereas had we been content to have sat still on Horseback, and fir'd as Horsemen, they would not have taken the Horses for so much their own, when Men were on their Backs, as otherwise; and withal they told us, that at last, if we had stood altogether, and left our Horses, they would have been so eager to have devour'd them, that we might have come off safe, especially having our Fire Arms in our Hands, and being so many in Number.

狼主要是想吃马。它们之所以那样奋不顾身冲上来，是由于看到了我们身后的马。一般来说，狼是怕枪的，但当它们饿疯时，就会不顾危险，只想抢马吃了。要不是我们连续开枪，并且最后用点燃火药的办法把他们吓退，我们大概早就给那些饿狼撕成碎片吃掉了。其实，只要我们安安稳稳地坐在马上，像骑兵那样向狼群开枪，它们看到马上有人，就不会把马看作猎物了。最后，他们又说，如果我们大家紧挨在一起，丢开我们的马，狼就一心只想吃马而不会管我们，我们也可平安通过，更何况我们有武器，而且人多势众。对我来说，这次遇险，是我一生中最可怕的一次。当时，我看到三百多个恶魔般的畜牲嚎叫着向我们冲来，张开大嘴恨不得一口把我们吞掉，而我们又无处可躲，无处可退，我以为一定完蛋了。

Duckbill valve installation: 1, straight-through lift-type check valve should be installed in horizontal pipe on the road, vertical lift check valve and bottom valve is usually installed in a vertical pipe on the road, and the bottom-up flow of media.

一、鸭嘴阀的安装使用： 1、直通式升降式止回阀应安装于水平管路上，立式升降式止回阀和底阀一般安装在垂直管路上，并且介质自下而上流动。

The influence of several parameters including injection rate of nozzle exit, the ratio of length between nozzle and inner gular tube, the ratio of length between gular tube and it's inner diameter and back pressure on the performance of gas solid injector is analyzed.

分析了喷嘴出口射流速度、喉嘴距、混合管段尺寸及背压等参数对气固喷射器性能的影响，结果表明：存在最佳的喷嘴出口射流速度、喉嘴距以及喉管长与其内径之比使得固气比达到最大值；而背压的增加则不利于提高喷射器性

Type YZF duck-billed valve, also be called "rubber flexible check-valve", it has function similar to tide gate, flapper gate but its working principle and structure is different, its mounting pattern is generally classed to pipe hoop form and flange form( flange form is generally used in case that latus rectum is larger than DN800, otherwise pipe hoop form is used).

YZF 型鸭嘴阀，又称"橡胶柔性止回阀"，与潮门，拍门功用相似，但工作原理和结构不同，其安装形式一般分为管箍式和法兰式（法兰式一般大于通径 DN800，管箍式一般小于通径 DN800），本体材质为橡胶，可广泛用于排水管出口，防止水流倒灌，造成事故。

P型蓄热式辐射管的燃烧系统是典型的单烧嘴蓄热式高温空气燃烧系统，具有系统结构简单，烧嘴连续燃烧而易于控制，以及烟气循环燃烧等特点。

The production line for both three layer PE pipe and epoxy powder inner anticorrosion pipe came from the reformation of an original production line of three layer PE pipe. The main problems to have been solved are as follows, convert the conventional spray gun deflector into two parts of diversion nozzle and gun wick to suit for different pipe diameters; adopt two stage retrieval equipment to increase powder retrieval rate and improve work environment; enlarge the calibres of gas jet and Venturi pump jet to increase powder output 20% above to ensure the spry coating thickness; design gun pushing device to raise automatic production level.

三层PE管和环氧粉末内防腐管兼容生产线是在三层PE管生产线的基础上改造而成的，主要解决了如下技术问题：将常规使用的喷枪导流体改成导流嘴和枪芯两部分，以适应喷涂不同直径钢管的需要；采用双级回收装置，提高粉末回收率，改善作业环境；加大一次气喷嘴和文丘里泵喷嘴的口径，使出粉量增加20%以上，从而保证涂层喷涂的厚度；设计推枪装置，提高生产的自动化程度。
