potential tube
解釋
測壓管-
Then, four different computation methods are applied to compute the hydrodynamic performance of the rotor, which are single - disk single - tube method ( sdst ), double - disk single - tube method ( ddst ), multi - tube method ( mtt ) that are based on momentum theorem and vortex method ( vtth ) that is based on potential eddy theory
然後，採用基於動量定理的單盤面?單流管方法（ sdst ） 、雙盤面?單流管（ ddst ）方法、多流管（ mtt ）方法以及基於勢渦理論的渦方法（ vtth ）計算直葉擺線式水輪機的水動力性能。 -
Trenchless technology given rised to the 20 centuries in abroad 70 ' s empress period, as an new construction technique in paving underground tube line. directional drilling come into being the most potential method because it achieve accuracy designed - area on trenchless technology, so it bring great benefit, especially in complexity pipe line area of city
非開挖鋪設地下管線施工技術（簡稱非開挖鋪管技術）是國外二十世紀七十年代後期發展起來的一項管道施工新技術，定向鉆進非開挖鋪管技術因其高精度的定位能力而成為非開挖四大工法之中最具潛力的技術，在城市管網極為復雜的地區，是其它施工方法難以代替的，社會經濟效益尤為突出。 -
In this thesis, we will focus on the nanotube structure and synthesis, including disorder multi - wall carbon nanotube, aligned multi - wall carbon nanotube array, cnx nanotube, and bcn nanotube. the effects of growth parameters, which provide scientific basis for pyrolysis of carbon nanotube, were studied systematically. furthermore, layered aligned multi - wall carbon nanotube arrays separate by catalyst particles were synthesized on the surrounding of reaction quartz tube by injection of xylene - ferrocene for the first time, which provided a chance for the accurate measure and potential use of carbon nanotubes
在對碳納米管制備的基礎上，全面系統地研究了碳納米管的影響因素，對熱解法制備碳納米管確定了可供參考的制備工藝參數，在些基礎上，首次成功地直接在反應爐內石英管壁上直接生長分層生長的定向碳納米管，為納米管的性質的測量提供了一定的基礎，而且為定向碳納米管在微電子學領域的應用提供可能性，能成功地實現定向納米管的固定長度生長。 -
These results indicated that it is practicable inducing exogenous dna into wheat through pollen tube pathway to obtain taget plant. there are great potential power to improve wheat quality by this way
本實驗結果表明：利用花粉管通道法將外源dna導入小麥中獲得目的性狀的植株，從而改良小麥品質，在實踐上是可行的，在生產中具有極大的潛力。
