It is by an electric pump pressure jar , tube of switch stone of the pressure and water gate make up 它由一个电泵压力缸，压力开关四通管和水闸门组成。
Thirty - two patients with sterility due to obstruction of fallopian tube treated by external application of tongguan powder 通管散外敷治疗输卵管阻塞性不孕32例
In the firm ' s opinion , the enterprise datwyler cabel system ( shanghai ) co . , ltd . introduces itself with connector and trunk 公司的详细介绍内包括关于连接器、联通管和行李舱的信息。
Tongguan zhuyun decoction combined with catheter enlarging and obstruction - removing method for treatment of 30 cases of obstructive sterility 通管助孕汤配合导管扩通术治疗阻塞性不孕症30例临床观察
Then , torsional alfven waves propagate upwards along the coronal loop and the carried wave energy can make a play in coronal heating 当被激发的扭转alfven波沿着磁通管向上传播到达日冕，其携带的能量就可以加热日冕。
Using the technique of fourier transformation , we can derive the alfven wave energy spectrum generated from convection turbulence modeled with kolmogroff - like power spectrum 这样，通过计算可以得到磁通管中被激发的扭转alfven能谱。

The emcn model is set up by use of flux - tube method . in this method , the segment in which the flux density is relatively even is considered to be an element , the permeance of each element can be calculated by use of conventional method . finally the permeance network can be set up by connecting each node with permeances , then the parameters and performance can be obtained 其基本思想是通过磁通管原理，把电机内部磁通密度相对均匀的部分看作一个单元，计算出单元的磁导，最后再把各个节点用等效磁导连接起来构成一个磁导的网络图，再根据电路的基本解法求得各个节点的磁位，从而求得电机的参数和性能。
