象限偏差 的英文怎麼說
中文拼音 [xiàngxiànpiānchā]
象限偏差
英文
quadrantal deviation-
These topologies of inverters are composed of two bi - boost dc / dc converters, they are symmetry. so whole circuit turn into four - quadrant converters, we can control every power mosfet on or off. then we can get sine wave with direct current polarization at the left, at the same we also can get sine wave with direct current polarization phase contrast 180 compared of the left at the right
這類逆變器由左右二個雙向boostdc / dc變換器構成，左右二邊是對稱的，所以整個電路構成了一個四象限變換器，我們可以恰當控制各功率管的開、關，使左邊的兩象限dc / dc變換器輸出一個帶直流偏置的正弦波，使右邊的兩象限dc / dc變換器輸出一個相差180度帶同樣直流偏置的正弦波形，這樣，負載zl上的電壓是左、右兩個dc / dc變換器電壓的差動輸出，正好可以消掉直流偏置，最終在負載r1上得到的就是正弦波。While this could hae biased diagnosis of localized prostate cancer, " increased multiitamin use due to early symptoms of prostate cancer cannot account for the increased risk of fatal prostate cancer among heay multiitamin users because the association persisted and een strengthened when we disregarded those diagnosed in the initial years of follow - up, " the researchers noted
研究人員稱，雖然這可能會使局限性前列腺癌診斷出現偏差， 「因出現前列腺癌早期癥狀而增加復合維生素用量不能解釋服用大量復合維生素的人其致死性前列腺癌風險增加現象，這是因為在最初幾年隨訪中當忽視那些早期診斷結果時，這種聯系也持續存在，甚至更強」 。While this could have biased diagnosis of localized prostate cancer, " increased multivitamin use due to early symptoms of prostate cancer cannot account for the increased risk of fatal prostate cancer among heavy multivitamin users because the association persisted and even strengthened when we disregarded those diagnosed in the initial years of follow - up, " the researchers noted
研究人員稱，雖然這可能會使局限性前列腺癌診斷出現偏差， 「而加大復合維生素用量會導致前列腺癌早期癥狀的說法不能解釋服用大量復合維生素的人其致死性前列腺癌風險增加現象，這是因為在最初幾年隨訪中當我們忽視那些診斷結果時，這種聯系卻持續存在，甚至加強」 。D finite element local analysis is done for hv porcelain post insulator by abaqus finite element software. the stress distribution of one - piece structure under dead weight, erection deviation, temperature change, wind load and short - circuited load is analyzed, which provides the scientific basis for security assessment of post insulator
以高壓瓷瓶支柱絕緣子為研究對象，採用abaqus有限元軟體進行三維有限元局部分析，分析了整體結構在自重、安裝偏差、溫度變化、風載以及短路電流載荷作用下的應力分佈，為支柱絕緣子的安全性評定提供了科學的依據。First, the paper makes the analysis of diffusion process of high - tech consumer products based on the theory of communication and consumer behavior, including information communication process and purchase process. we can see specific receiver, appropriate time, reachable channel and correct information can bring effective communication of information. purchasing power, product feature, perceived risk, definite knowledge of product and usage, consumer habit, purchasing environment and buying time all influence purchase behavior of consumer
首先應用傳播理論和消費者行為理論，通過對高科技消費品市場化過程的分析，包括對企業信息傳播過程的分析和消費者購買過程的分析，得出信息有效傳播依賴于明確的目標對象、恰當的傳播時機和渠道選擇以及不會存在理解偏差的信息；消費者購買能力、產品特性、消費者知覺到的風險、消費者有限的產品知識和使用知識、消費者習慣、購買環境、購買時間都會影響到消費者的購買行為。Taking no account of the non - uniformity of the detector, this paper analyzed the performance of the traditional four - quadrant angle - measurement algorithm and two other algorithms in calculating the pitch angle and the deflection angle of the incident ray, and also compared the error curve of the pitch angle calculated by each algorithm in the full plane
摘要在不考慮探測器非均勻性影響的情況下，本文分析了傳統四象限測角演算法和另外幾種演算法在計算入射光的俯仰角和偏轉角時的性能，還比較了在整個平面內各個演算法得到的俯仰角的誤差曲面。The software can design many conventional type of cam, concluding cam - plate with middle follower, cam - plate with offset follower, cylindrical cam, dividing cylindrical cam, and cylindrical cam with space curve, etc. in forming working curves of cam - plate, used the approximation by arcs which can lessen the nodal points on curves of cam uttermostly in same error, so it reduce the computation time and relieve the chattering of principal axis. in former times, to cam mechanism, the follower only has one direction motion
本軟體可以設計的凸輪類型較多，包括了對心移動從動件盤形凸輪、偏置移動從動件盤形凸輪、圓柱凸輪、圓柱分度凸輪和空間曲線柱形凸輪等，其中對盤形凸輪的工作曲線採用了難度較大的圓弧逼近演算法和等誤差演算法，這樣就可以在相同的允許誤差內最大限度的減少生成曲線的節點數，減少計算時間，同時可以大大減輕加工中的振動現象。It ' s more and more distinct that the contradictory between the further developing of venture capital and behavior of excessive interference and imperfect supporting polices from government focusing on the characteristics of behavior, four main reasons are thoroughly analyzed : 1 ) the conventional system, 2 ) the limited capacity of governor who decided the policies, 3 ) the result of public selection, 4 ) the polices environment in order to accelerate the development of venture capital industrial, the favorable viewpoint put forward in the diesis is tiiat : die foremost task put forward for establishing and perfecting capital market, ttn superior policies and laws and macro - scope situation
政府主導下的風險投資運作體制日漸成為風險投資發展中的嚴重障礙，政府行為越位現象突出；相反，政府作為制度安排者，在營造風險投資發展所需的法律、政策、市場等環境方面又很不到位，政府行為不到位的特徵明顯。由此可見，政府參與微觀經濟過度及在營造制度環境方面力度不夠，成為政府在風險投資發展過程中的雙重行為缺陷。除此之外，受主觀因素和客觀環境的限制，政府在制定有關鳳險投資發展的政策時出現一些政策偏差和失誤，也成為政府在風險投資發展中的行為特徵之一。On the basis of previous work, we developed a new data processing system by use of dsp & oop. the new system overcame the problems existed in the old data processing system successfully, such as the bug which cause program dead loop when the data is too long, and the frequency leak due to principle limit of fft filter. in addition, we eliminated the measurement error brought on by phase warp
我們在前人的工作基礎上，利用現代數字信號處理技術和面向對象的軟體開發技術，統一了彈上黑匣子數據處理系統的操作平臺，完善了轉速、掃描角測試數據處理系統，修正了原有處理程序中的因數據長度過長而導致程序死鎖的bug ；利用有限沖擊響應（ fir ）濾波器，在濾去噪聲的同時，有效地解決了矩形窗fft濾波的頻譜泄漏問題；另外還解決了因相位偏差而導致的測試誤差。分享友人
