A Constant Volume Sampling System with super Critical Flow Venturi flux meter is developed based on Bernouli fluid equation.

基于气体伯努利流动方程，开发了带超临界流文丘里管流量计的定容系统，即CFV-CVS。

Mathematical model for discharge coefficient of orifice - plate flow - meter is presented and tested on the basis of literature data.

化工生产过程中，常常用到孔板流量计或文丘里管以测定管路中的流体流量。

It is proved that the model is in good agreement with the literature data. Standard error is less than 0.01(σ.01). Using this model, process simulation of the experiment of the test of orifice - plate flow - meter is carried out on computer.

在孔板流量计或文丘里管的计算过程中，习惯上常常使用查表的方法以确定孔板流量计的流量系数，但是，在化工过程模拟计算过程中，这种方法却难以奏效。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。

The factory affiliated to the Group primarily manufactures multiple-purpose pincers, baking kits, knives, scissors, kitchenware, gardening tools and beauty care kits as well as other hardware tools, the annual production value of which reaches US$ 30 million dollars.

集团所属工厂主要生产多用钳、烤具、刀具、剪刀、厨具、花园工具、美容套等五金产品，年生产总值3000万美元，产品价廉物美、选料上乘、质量保证，深受国内外客户的青睐
