The analytical theory of the former method is relatively mature, but the unified analytical theory in the stretched spectra of one axis and two axes will improve yet.

In this paper, tridimensonal analysis of the electronic spectra in the method of stretched PVA film was investigated, on the basis of resut that orientation axis of one axis stretch exists in the orientation plane of two axes stretch, and a method used orientational distributive function to quantitaively analysis the determination results was advanced in the method of stretched PVA film of one axis and two axes.

To simulate the complicated foree-bearing condition of high arch dam concrete for Ertan Project,the strength and deformation experiment research for biaxial,friaxial compression,tension in one axis with compression in other one or two axes of concrete specimens is conducted by using of prepared multifunctional true friaxial compression apparatus.

Usually,transformation between quaternion and Euler angle is constricted to Euler angle's value from negative 90° to positive 90° in three axes or one axis.

A conventional SAR only measures the location of a target in a two-dimensional coordinate system, with one axis along the flight track (“along-track direction”) and the other axis defined as the range from the SAR to the target (“cross-track direction”).

First, the dynamicmodels is established by Lagrange Equation. The equivalent model is given with each lumpmass located on one axis by linear transformation and proper general axes. Therefore, theoriginal model is transformed to the three kinds of typical flexible transmission systems.

The case where a constant compressive stress is applied along one axis and a varying stress along the other, is solved in detail.

Derived semifield planes of odd order admitting non-trivial involutorial affine homologies with more than one axis, are examined in detail, under the assumption that the group generated in the translation complement is dihedral.

This makes it possible to determine the finite elastic-plastic deflections of beams with various cross-sections, with at least one axis of symmetry, and made of multiple linear strain-hardening materials.

Variation of subsect.Biflores was traced along one axis, the species of subsect.Australes as well asSaxatiles were found along the other axis.

Often more than one axis arises from a single holdfast, probably as the result of compounding rather than proliferation.

The image force on the dislocation near an elliptical hole is calculated by confor-mal mapping technique. Allowing one axis of the ellipse to dwindle to zero, the crack limit solution is obtained.

本文利用保角变换方法计算了近椭圆孔边位错象力。将椭圆一轴缩小到零,得到了裂纹情况的位错象力。

Spectral analysis technique is a powerful tool for evaluating random noise of inertial sensors. In this paper, noise measurement has been performed on a two-degree-of-freedom dry tuned gyroscope. The experiment was carried out on a precise servo table with single axis. One axis of the gyro was captured by a torque feedback loop simultaneously. The noise frequency range of interest was limited to 0.008 Hz. The test duration was 48 hours. The procedure of data processing includes. rejecting wild data,...

Spectral analysis technique is a powerful tool for evaluating random noise of inertial sensors. In this paper, noise measurement has been performed on a two-degree-of-freedom dry tuned gyroscope. The experiment was carried out on a precise servo table with single axis. One axis of the gyro was captured by a torque feedback loop simultaneously. The noise frequency range of interest was limited to 0.008 Hz. The test duration was 48 hours. The procedure of data processing includes. rejecting wild data, resampling, checking the stationarity of the random data series by utilizing regression analysis method. The gyro noise spectrum has been obtained based on the Rader's algorithm. Some suggestions of how to carry out better spectral estimation have been raised in the last part of this paper.

In this paper four model following approaches are used to design Hydraulic Velocity Flight Simulation Table with One Axis. In using real model-following approach to design this system we discuss the problem of how to introduce input into the synthesized regulator system. In this paper we use a configuration somewhat different from that in the references [1] [2] [3]. When calculations are made with the formulas derived from our new configuration, the results show that the configuration in this paper can...

In this paper four model following approaches are used to design Hydraulic Velocity Flight Simulation Table with One Axis. In using real model-following approach to design this system we discuss the problem of how to introduce input into the synthesized regulator system. In this paper we use a configuration somewhat different from that in the references [1] [2] [3]. When calculations are made with the formulas derived from our new configuration, the results show that the configuration in this paper can bet- ter follow the model than that in the references. In order to obtain satisfactory closed-loop transient characteristics a new method is introduced for choosing the weight matrices Q for rea1 model- following and type-zero perfect model-following' The weight matrices of the quadratic performance criterion are chosen according to the following formulas: Q=[q_(11) q_(22) q_(nn)] q_(11)=b_1~2-a_1~2 q_(22)=b_2~2-a_2~2-2(b_1 b_3-a_1 a_3) ………… q_(11)=b_i~2-a_i~2+2∑_r(-1)~r(b_(i-r)b_(i+r)-a_(i-r)a_(i+r)) ………… q_(nn)=b_n~2-a_n~2-2(b_(n-1)-a_(n-1)) When the weight matrices are so chosen the systems obtained certainly possess satisfactory dynamic character. In this paper for all four approaches we derive formulas for our given problem and perform calculations on digital computer.
