水流

Over the past few years, the company and make unremitting efforts to form an automatic sprinkler fire extinguishing system-oriented products, have developed a fixed artillery fire extinguishing systems, foam extinguishing systems, gas fire extinguishing system, such as series of fire protection products, the current main Products are: sprinkler nozzle series, wet alarm series, deluge valve series, the flow indicator series, water spray, water curtain fire sprinkler control valve series series, in particular the PS20 - PS80 fire water cannons, PSKD30 - PSKD60 electric artillery fire control, PHY Series storage pressure of air bubble mixing device, such as the proportion of products in the domestic market by the user's consistent high praise, has great competitive advantage.

几年来，公司经过不懈的努力，形成了以自动喷淋灭火系统为主导产品，相继开发研制了固定消防炮灭火系统，泡沫灭火系统，气体灭火系统等系列消防产品，目前主要的产品有：洒水喷头系列，湿式报警系列，雨淋阀系列，水流指示器系列，水雾，水幕喷头系列消防控制阀系列，特别是PS20--PS80消防水炮，PSKD30--PSKD60电控消防炮，PHY系列贮压力使空气泡沫比例混合装置等产品在国内市场受到用户的一致好评，具有很大的竞争优势。

The arrow direction on the switch has to be consistent with the direction of the flow.

安装时，阀体上的箭头必须与实际水流方向一致，阀门的进出水端应安装一段长度为15倍该管径的直管。

The water won't go down, I think the pipe must be clogged with kitchen waste.

水流不下去，我想肯定是水管被厨房里的垃圾给堵住了。

A continuous purge is currently discharged to controlled waters and made up from water pumped from the site reservoir which is fed by mines drainage or from canal.

源源不断的水流被及时排泄到控制下的用水系统中，并由从现场的蓄水池中抽出的水加以补充，而蓄水池中的水则由矿区的排水系统或小渠供给。

In the experi- ment and practice m the zhongwei North Main Canal of the Hetao Irrigation District, a cheap and quick functioned slope protection method of soil and grass mixture for tree planting has been searched for de- sign and construction of irrigation canal and drainage in the desert region.

河套灌区在中卫北干渠进行了试验，在沙漠建渠道，用人工和植物固沙，沙漠区排水沟道的设计则充分考虑水流冲刷，对沟道防坍塌摸索了一条花钱少、见效快的草上植柳护坡办法，并在灌区内植树造林以固沙。

For example, the 3/4 (20mm) 70A-T used for smaller domestic and residential requirements, passes over 10 gpm (38 lpm) with a 10 psi (70 bar) pressure drop.

例如，通径DN20的型号70A-T用于较小的室内和住宅环境，在10 psi (70 bar)压降下，水流流量为38公升/分钟。

Buy low-flow showerheads — Using aerators in your faucets and installing low-flow showerheads can cut your family's water bills by 50% while helping to conserve our water supply.

购买水流小的淋浴喷头——在龙头中安装通风发散装置和安装低流量的淋浴喷头可以减少50%家庭水费的支出，同时也促进了水资源的保存。

Anacondas live in swamps, marshes, and slow-moving streams, mainly in the tropical rain forests of the Amazon and Orinoco basins.

它们生活在沼泽，湿地和水流缓慢的溪流中，主要分布在亚马逊热带丛林和奥里诺科河盆地。

It should be noted that pump signs marked on the head and the use of water lift there is a difference, this is because of water through aqueducts and pipes must be near the resistance loss.

必须注意，水泵标牌上注明的扬程与使用时的出水扬程是有差别的，这是由于水流通过输水管和管路附近时会有一定的阻力损失。

It is found that (1) the aquatic protozoa communities consists of thirty-six taxa in twenty-six genera and twenty-four families;(2) the groups of ecological function include: Photosynthetic autotrophs (P groups, 25%), Bactivores detritivores (B groups, 44.44%), Saprotrophs (S groups, 2.78%), Algivores (A groups, 11.11%), Nonselective omnivores (N groups, 11.11%) and Raptors (R groups, 5.56%);(3) according to the characteristics of karst water, substrates and mosses, four ecological types and eight sub-types of aquatic protozoa communities can be distinguished.

2水生原生动物群落含6个功能营养群。其中，原生动物光合营养群（P群，Photosynthetic autotrophs），占总数的25%；细菌取食者群（B群，Bactivores detritivores），占总数的44.44%；腐生营养类群（S群，Saprotrophs，占总数的2.78%；食藻者类群（A群，Algivores），占总数的11.11%；非选择性杂食者群（N群，Nonselective omnivores），占总数的11.11%；食肉者群，占总数的5.56%。(3)根据岩溶水流、基质和藓类植物特征，划分该区附生水生原生动物生态群落为4个类型和8个亚类型。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
