MPH plastic magnetic pump complies with JB/T7742-1995Standard for Small Magnetic Transmission Centrifugal Pump. Its flow-through parts adopt PPS with corrosion resistance to most acid, alkali and salt (except oxidable acid like strong sul-furic acid, nitric acid and aqua regia). Its performance is close to the chemical performance of F4, which can resist to most organic solvents under 100℃, especially to the mixture of gas and carbinol. Thus it is an ideal pump for acid and alkali industries.

The possible reason is that doped Zr〓 ion enters the interstitial sites for its small ionic radius and no dipole complexes were formed. Monovalent ion F〓 has been reported to improve the scintillating performance greatly. Our results show that Agrand diagrams of F〓: PWO crystals obey an modified Cole-Cole equation. The crystals present similar dielectric relaxation phenomena to but have much higher activation energy than that of RE〓: PWO crystals, which originate from the 〓 dipole complexes. The co-doping of trivalent Y〓 and pentavalent ion Nb〓 does not always show a better scintillation performance than that of solely doped samples, which could be attributed to the existence of the 〓 dipole complexes, which counteract the solely doping effect.

而Zr〓由于离子半径太小，可能进入间隙位置，不形成类似的偶极缺陷；一价负离子F〓的掺入提高了晶体闪烁性能，阻抗谱测试结果表明F〓：PWO晶体Argand图符合修正的Cole—Cole方程，晶体同样表现出介电弛豫现象，并具有比RE〓：PWO晶体中高得多的弛豫激活能，可能起源于形成的〓偶极缺陷；Y〓和Nb〓双掺的PWO晶体并没有显示出两种离子单掺优点的叠加，阻抗谱测量结果表明，在双掺晶体中可能形成〓偶极缺陷，使两者掺杂作用相互抵消。

The process of designing the performance, The Taiwan Indigenous Culture Park in order to compromise cultural authenticity, performance requirements and dance accompanied by music, The Taiwan Indigenous Culture Park chose the indigenous culture which has performable ingredients to The Naluwan Theater.

而在乐舞产制的过程中，园区在在文化真实性、展演需求及乐舞商品化的妥协之下，园区选择了将具有表演成份的文化元素搬上舞台。

If no one cares enough about the system being "performant"(neither a requirement nor a word) to pay for performance trials, then more than likely performance doesn't matter.

如果没有人非常在乎系统是否足够高效（既没有需求也没有类似的言语）来应对性能试验，那么很有可能性能是无关紧要的。

In conclusion,lacking for choline and methionine led to decrease growth performance decrease and tibia with short disease; Basal diet supplemented with 750 ppm – 1250 ppm Cholin improved Growth performance ,and prevented the occurrence of perosis. Higher dietary choline can alleviate the adverse effects of methionine and choline deficiency.

总结而论，缺乏胆碱与甲硫胺酸会导致生长性能下降和胫骨粗短症；饲粮中添加750~1250 ppm之胆碱可以改善生长性能及防止胫骨粗短症的发生；饲粮添加高剂量的胆碱，可以缓和甲硫胺酸和胆碱缺乏之不良影响。

It was found that silicalite-1 and β zeolite membranes both possess fairly good separation performance for PhOH/H2O, and C6H6/H2O and that the performance of β membrane for PhOH/H2O is better than that of silicalite-1 one.

结果表明：Silicalite-1和β沸石分子筛复合膜均具有明显的分离性能；在分离苯酚溶液时，β分子筛膜的性能优于Silicalite-1分子筛膜，两者的平均脱除率分别为69.9%和51.5%。

Through the comparison of calculation results of two methods in the uniform and the non-uniform inflow, it is found that the results by two methods are very close. The calculation results by two methods are compared with open water test, and the agreement is well. The two methods can both perfectly simulate the hydrodynamics performance of podded propeller, and the method of induced potential needs less program work and can save a great deal of calculation time and memory space. It is a simpler and effective method to calculate hydrodynamics performance of podded propellers and other combined propulsions.

经过用两种方法对均匀来流和非均匀来流条件下水动力性能的计算比较，发现两种方法的计算结果很接近，并与模型试验结果吻合得很好，但用诱导速度势的方法编程工作量较诱导速度方法少，而且还可节省大量的计算时间和存储空间，是一种计算吊舱推进器和其他组合推进器水动力性能相对简单而且有效的方法。

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