In fact, it is the special system of our country that increase the incoherence and unconditionally of all the stockholders and the lack of the true investors. these two elements increase the stockholders " dissimilated behavior. in dividend policy, the difference of payment level resulted from the variance of the controlling degree embodies not the difference of stockholders " decision making to increase the company " value but the particular preference of the nonnegotiable shareholders and the management
而最根本的原因是由於我國特定製度安排導致了股東群體的非一致性和非制約性的強化以及真正投資主體的缺位，兩個因素的共同作用加劇了股東行為的異化，表現在股利政策上，由股權控制度變化產生的支付水平差異主要體現為非流通股股東及管理層的特殊偏好，而從質的角度，以公司價值為目標的真正股東化主體的決策差異分析無效。 -
For a general linear model ( input matrix is deterministic ), under a certain conditions on variance matrix invertibility, the two estimates can be identical provided that they have the same priori information on the parameter under estimation. even if the above information is unknown only for the optimally weighted ls estimate, the sufficient condition and necessary condition, under which the two estimates are identical, is derived. more significantly, we know how to design input of the linear system to make the performance of the optimally weighted ls estimation identical to that of the linear minimum variance estimation in case of being lack of prior information
在一般線性模型（即輸入矩陣為確定性）下，當兩種估計都利用有關被估參數的先驗信息時，二者在方差陣可逆的一定條件下可達到一致；當最優加權最小二乘估計不利用此先驗信息時，存在二者一致的充分條件和必要條件，進而找到一種設計輸入矩陣的方法，使得在先驗信息缺乏的條件下，仍可利用最優加權最小二乘估計達到與線性最小方差估計一樣優越的估計性能。 -
By simulating mathematically on frequency and on space, we can find the average speed of space field and the average speed of frequency field that is weighted by amplitude, and analyse their relation, and analyse the meaning of space speed variance x and frequency speed variance v. in the fourth part, how to ensure the height of cloud is introduced, and basing on the theory of wind field continuity, the height updating quality controlling is introduced. in the fifth part, the system of cloud wind is introduced, we tracked cloud - motion of consecutive satellite images with one - minute interval by the 1 - d fourier analysis technique and the two - dim fourier analysis technique and the fft analysis technique, and dispose them with quality controlling. in the sixth part, we summarized our research and put up with shortages of this article
模擬模塊內各點的速度線性變化時，得到空間域平均速度以及頻率域以振幅為權重的平均速度，分析了空間域平均速度和頻率域以振幅為權重的平均速度的關系，並揭示空間域的平均速度的標準差_ x和頻率域的振幅為權重的平均速度的標準差_ v的意義，以及它們之間的關系；第四章介紹了雲跡風系統的高度指定以及風矢高度的劃分，並根據風場連續性原理，介紹了高度調整法的質量控制；第五章介紹導風系統的流程，選擇了三個時刻的ir雲圖，分別用一維傅立葉相位法、二維傅立葉相位法和快速傅立葉演算法計算一個風場個例，並對所得風場進行質量控制，並給出風場圖；第六章進行研究總結，指出不足和有待于進一步研究之處。 -
Usually we linearize them approximately in industrial process, but in some cases this ca n ' t satisfy the request of automatic control which makes us consider the nonlinear factors in the industrial process. in practical process of power plants the typical structure nonlinear case is dead - zone and the latter case is the nonlinear variance of objects ' parametres with the changes of working condition. the nonlinear research is parallel with the linearity and adaptive method can be used to deal with nonlinear cases. in this paper two adaptive control methods are used to solve the problems brought by the dead - zone of boiler negative pressure system and the nonlinear changes of the milling system ' s character parameters, which achieved good results
在生產中通常對非線性作近似線性化處理；但在某些情況下線性近似達不到自動控制的要求，必須對生產過程中的非線性情況進行考慮。在火電廠的實際生產中，典型的結構非線性之一是死區；參數非線性多發生在控制對象特性隨工況變化而變化，表徵其特徵參數變化呈非線性。非線性控制的研究與線性控制的研究是并行的，針對非線性情況，可以採用自適應的控制方法。 -
The presented dissertation mainly discusses the non - linearity existing in monostation and multistation radar measurement. the first part of this dissertation integrated the non - linearity with the uncertainty of measurement system, and presents a secondary order filter for correcting measuring variance while the measurement equation is non - linear. by comparing the filter error of extended kalman filter with that of secondary order filter, we find the filter performance of these two filters are almost same
本文主要討論單站與多站雷達中的非線性測量問題，在1中，我們把測量系統的非線性與測量系統的不確定性聯系起來，針對只有測量方程是非線性的情況，給出了一種修正測量方差二階濾波器，並用這種二階濾波器分析了推廣kalman濾波器的濾波誤差，指出推廣kalman濾波器與二階濾波器相比，濾波性能幾乎相同。 -
When the two - dimensional decoupling theory is applied to single - mode and two - mode dye laser system, the mean ( i ), variance 2 ( 0 ), and effective eigenvalue eff of laser intensity are calculated. excellent agreement between theoretical analysis, numerical simulations, and experimental measurements are obtained
然後將二維退耦理論應用到單模和雙模染料激光系統中，算出了激光場的平均強度< i > 、強度方差_ 2 （ 0 ）和有效本徵值_ （ eff ） ，理論分析與數值模擬和實驗結果符合得很好。 -
Abstract : aiming at the intrinsic defects of minimum - variance adaptive controllers, fuzzy controy algorithm is introduced into standard minimum - variance control. simulation results show that the two algorithm ' s combination makes the system acquire an excellent control effect
