回压

Another some of characteristic of this equipment is: Go up automatically line, self-adjusting control a foot, automatic reinforced stitches reachs backstitch; The change spending type of all sorts of stitch amounts to 80 ～ 190 kinds; The automatic lubricant system protecting clean of initiate, oiliness bearing, durable and safe clutch, make this equipment needs what lowest is restricted to maintain only.

此设备的另一些特点是：自动上线，自动调节压脚，自动回针及倒缝；各种针法的花式变化达80～190种；首创的自动润滑保洁系统，含油轴承，耐用安全离合器等，使该设备只需最低限的保养。。。

Fill up the stability of direction of press press spring back for aggrandizement air, NIKE the company publishs section of new shoe of the 3rd season, roll out humorous mode air cushion , be just as increase like bedspring avoid shake protection holds trends of the body that have a shoe concurrently to stabilize.

为强化大气垫受压回弹方向的稳定性，NIKE公司发表第三季新鞋款，推出谐调式气垫，如同弹簧般增加避震保护兼具鞋身动态稳定。

He remembered the boomerang that Ken had pressed into his hands.

他记得了回飞棒那一个肯恩已经进入他的手之内压。

Currently, domestic production has successfully developed a PWR Island Grade Ⅰ electric valve, check valve; Nuclear Grade Ⅰ electric bellows globe valve, fast breeder reactor using nuclear electric bellows Ⅱ grade cut-off valves with sodium high level of nuclear valves.

目前，国内已成功研制生产了压水堆核岛核Ⅰ级电动闸阀、止回阀；核Ⅰ级电动波纹管截止阀、快中子增殖反应堆用核Ⅱ级电动波纹管钠截止阀等具有较高水平的核级阀门。

You must prevent circumfluenting to the boiler if the boiler closes chake valve. Rail pressure valve and buffer pistons in the act of gravity can realize the pressurize immediately to make the steam and condensate water not to circumfluent to the boiler in low pressure.

如果锅炉没有关闭截止止回阀，则必须防止回流到锅炉上，阀瓣压铁和缓冲活塞，在重力的作用下，能够迅速实现密封，使得蒸汽和冷凝水即使在低压下也不会回流到锅炉里。

If the boiler don't close the check valve, then must prevent back flowing to the boiler, valve clack mould weight and buffering piston can seal under gravity action, they make steam and condensed water can't flow back to the boiler under the low air pressure.

如果锅炉没有关闭截止止回阀，则必须防止回流到锅炉上，阀瓣压铁和缓冲活塞，在重力的作用下，能够迅速实现密封，使得蒸汽和冷凝水即使在低压下也不会回流到锅炉里。

With the affects of tgravity, the valve clack and damper piston can get sealed immediately that steam and condensed water won't refluence to the boiler even in an atomosphere of low pressure.

如果锅炉没有关闭截止止回阀，则必须防止回流到锅炉上，阀瓣压铁和缓冲活塞，在重力的作用下，能够迅速实现密封，使得蒸汽和冷凝水即使在低压下也不会回流到锅炉里。

Because the past auto-recorder has only one flow-meter, constructers has to grout with the so called Minor Cycle Grouting Method , which has huge influence on the grout properties and strength of the coagulum, sometimes even results in drilling accident.

同时，在孔内不吃浆或衡压屏浆阶段，由于孔内吃水不吃浆，变浓的浆液又不能和浆桶内的新浆混合，会导致浆液迅速回浓、比重变大、极易在灌浆孔内沉淀造成埋钻事故。

The mostly important influence factors of hysteretic behavior, such as: the different forms of internally longitudinal stiffeners in the tube cross section and axial load ratio are considered in the design of specimens.

试件设计时主要考虑截面设肋形式和轴压比对滞回性能的影响。

Simply place work on spring-loaded, perforated dasher plate, press down and agitate, then release to return dasher to drain position.

简单的将工作放置于弹簧式多孔搅拌板上，压下并搅拌，然后释放，将搅拌板回放至出水口的位置。
