Research of time phases property of neuroendocrine immune and hemorheology on deficiency of cold and hot syndrome rats 免疫與血液流變學的時相性研究
In the past , the research for multi - phase transmission system is confined to the multi - time phases of 3 , that are 6 , 12 phases , and so on 以往多相輸電的研究,僅限于相數(shù)為3的倍數(shù)相,如6相12相等。
Nevertheless , to further minimize the risk of traffic accidents at this junction , td has already adjusted the traffic lights so as to provide a separate time phase exclusively for the right - turn movement 不過,為進一步減低在這路口發(fā)生交通意外的危險,運輸署已經(jīng)調(diào)校該處的交通燈號,撥出一段時間專供車輛右轉(zhuǎn)。

Result : in each time phase , there was no significant difference between vessels in control group and expriment 1 , both groups showing satisfactory effect in the measurement of oxygen consumption volume and nbt tintation times and examination of histopatholoy and ultrastructural morphology and patency rate of cryopreserved allograft arteries 結(jié)果:在各個時相,實驗組i和對照組的nbt染色的時間和氧耗量皆無統(tǒng)計學差異( p > 0 . 05 ) ,而實驗組ii和對照組的nbt染色時間和氧耗量統(tǒng)計學差異顯著。
The innovation capability does not increase in case acting on one ' s own , introduce from elsewhere near the technique blindly , be difficult to shake off the behind the times phase of technique always , one there is not the innovation capability nationality , be difficult to stand erect to well - developed nationality of the world woods 創(chuàng)新是一個民族進步的靈魂,是一個國家興旺發(fā)達的不竭動力。如果自主創(chuàng)新能力上不去,一味靠技術(shù)引進,就永遠難以擺脫技術(shù)落后的局面,一個沒有創(chuàng)新能力的民族,難以屹立于世界先進民族之林。
Integrating tynman system with polarized system together , the laser interferometer is compatible for the surface with different reflectance . first , on the basis of synthesizing different interferometric microscope , the author introduced a kind of lase interferometer combining polarized interferometry and real - time phase detection algorithms . first , a kind of optical configuration is introduced , which is realized in the above interferometer 本文在分析了國內(nèi)外不同干涉顯微系統(tǒng)的基礎上,根據(jù)干涉顯微測量方面的需求提出了采用偏振干涉和條紋掃描方式實時檢測波面位相的激光干涉顯微系統(tǒng),提出了一種可用于表面微觀輪廓及粗糙度參數(shù)測量的光學顯微干涉系統(tǒng)的光路,然后介紹了條紋掃描波面位相實時檢測技術(shù)以及四步移相法,并在此基礎上完成了光學系統(tǒng)及相關的機械結(jié)構(gòu)。
