Easily installed between ANSI flanges, the Westfall 2350 Series Venturi Flow Meter has a short laying length design and provides low permanent pressure loss.

可在ANSI法兰之间轻松安装，Westfall 2350系列文丘里流量计提供很低的永久压力损失。

Two mathematical models have been deduced in the case of dense-phase and light-phase conveying respectively. Combining the capacitance phase concentration sensor designed and the traditional Venturi flow meter, the powder velocity and instantaneous mass flowrate are obtained by measuring concentration and differential pressure signal.

本文最后提出了一种差压—浓度法测量气/固两相流瞬时质量流量的新方法，分别建立了稀相和浓相输送情况下的粉料速度和流量测量的数学模型，即将所研制的电容式相浓度传感器与传统的文丘里流量计相结合，通过测量浓度信号及差压信号，求得粉料的传送速度及其瞬时质量流量。

Series 7 should be installed downstream of the water meter and of the water pressure regulator.

系列7应该安装在水表和水压力调节器的下游。

The intensity and way of the cold high atmospheric pressure center,Ф568 (the latitude at the nodical point of the 5680 geopotential meter line with the 120°E line in the 500hPa high altitude) and Ф850(the latitude at the nodical point of the 0℃ temperature lute with the 120°E line in the 850hPa high altitude) were closely related to the minimum temperature. The equation of short-term forecast of low temperature weather for Fuzhou, Xiamen and Shaowu was established by stepwise regression analysis. The detemperature rate was estimated by cloud cover, wind velocity, humidity (N20, F20, U20) at 20:00 o'clock.

通过对历史资料分析，利用逐步回归分析方法分别建立了福州、厦门和邵武三个探空站最低气温t的短期预报方程，再利用各地当晚20时的云量、风速、湿度(N20、F20、U20)值估算当晚的降温幅度、进一步对最低气温t进行短时临近预报，然后结合各地果树主栽品种及其抗低温冻害指标、及时发布低温冻害预警预告，构成了福建省冬季果树冻害低温预报预警模式。

Usually includes water depth 200 meter below the complete waters, is all year long dark, the sunlight cannot infiltrate completely, the salinity is high, the pressure high, the water temperature is low and is constant, the aquatic plant cannot grow, the animal type and quantity are deficient, and mostly is the detritus animal, only then the few sarcophagy animal, and along with the sea water depth increases, but reduces unceasingly.

通常包括水深200米以下的全部水域，终年黑暗，阳光完全不能透入，盐度高，压力大，水温低而恒定，水生植物不能生长，动物种类和数量非常贫乏，且大多属碎屑性动物，只有少量肉食性动物，并随海水深度增加而不断减少。

C8051F005 is the control center of the survey meter, the signal is obtained by jaw pressure transformator and current transformator. Direct Digital Frequency Synthetics technology is adopted to automatically adjust the frequency of the actuating signal and avoid the interference of the signal in the ground network.

该检测仪采用C8051F005单片机作为控制处理中心，钳口式电压互感器和电流互感器检测接地电阻信号，运用直接数字频率合成技术自动调整激励信号频率，从而避免地网中干扰信号源的影响。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
