显示摘要
PROBLEM TO BE SOLVED: To provide a method for measuring the density of precipitate particles capable of precisely measuring the particle density by easily measuring the surface density of precipitates and thickness of a sample while reducing a problem of counting loss in surface density measurement of precipitates.SOLUTION: The thickness of a sample is obtained by X-ray absorption difference method from the intensity ratio of a K-lay of a characteristic X-lay and an L-lay of a characteristic X-lay different from each other, which are emitted when irradiating with an electron ray a base material sample of a metal of copper, iron, cobalt or nickel. The areal density of the precipitate is measured from the characteristic X-ray image obtained by mapping characteristic X-rays to precipitates in the sample. From the thickness of these samples and the areal density of the precipitates, the particle density of the precipitates in the sample is calculated.SELECTED DRAWING: Figure 1 【課題】析出物の面密度測定の際の数え落としの問題を低減するとともに、析出物の面密度と試料の厚さとを簡易に計測して、その粒子密度を正確に測定する。【解決手段】銅、鉄、コバルト又はニッケルからなる金属の母材試料に電子線を照射して放出される異なる特性X線のK線と特性X線のL線の強度比からX線吸収差法により試料の厚さを求めるとともに、試料中の析出物に対する特性X線をマッピングした特性X線像から析出物の面密度を測定し、これら試料の厚さ、析出物の面密度から、試料中の析出物の粒子密度を算出する。【選択図】 図1

显示摘要
A thermal flowmeter is used to measure the mass flow of a medium of gas or liq. through a conductor. It consists of a metal tube carrying the medium with a heater and temp. measurement sensors. The electrical power extracted from the heater is a very accurate measure of the heat transferred to the medium. The ratio of power transferred to the increase in medium temp. is very accurately proportional to the mass fear. The heater consists of a thin film layer (3) of resistive material on an electrically insulating substrate (2) of good thermal conductivity. The substrate is thermally connected to the external surface of the metal tube (1) via an intermediate metal layer (4). Further tube sections (6,10) with thin film resistors can be used for upstream and downstream temp. measurement.

PCT No. PCT/EP94/01789 Sec. 371 Date Jan. 31, 1995 Sec. 102(e) Date Jan. 31, 1995 PCT Filed May 31, 1994 PCT Pub. No. WO94/29740 PCT Pub. Date Dec. 22, 1994.Described is a sensor based on the magnetoresistive effect and integrated into the thin-film arrangement of a remagnetization line in the form of a meander. In an adaptation to this meandering structure, the magnetoresistive film strips are provided in regions with alternating positive- and negative-inclined Barber pole structures. When periodic remagnetization of the regions takes place, a drift-free AC voltage is obtained as a sensor output signal. This lack of drift is the presupposition for the use of the magnetic field sensor for precise measurement of weak magnetic fields.

显示摘要
Disclosed is an on-line detection device for the tension of suspension ropes (2) or stabilising ropes (3) in a construction vertical shaft, the device mainly being composed of tension detection devices (4) arranged on masts (6) and a steel wire rope frequency detection portion arranged on the surface of a shaft opening. The tension detection devices mainly comprise inclined surface supports (4-3) fixed on the masts (6) of sheaves (5), pressure sensors (4-2) fixedly mounted on inclined surfaces of the inclined surface supports (4-3) and bearing supports (4-1) fixedly connected to the pressure sensors (4-2). The steel wire rope frequency detection portion mainly comprises frequency detection devices (7) and a signal collector used for collecting frequency signals. The propagation frequency of vibration waves on a steel wire rope is periodically detected via a steel wire rope frequency detection device (7) arranged on a shaft cover platform (8), and the tension of the steel wire rope is obtained via the steel wire rope length 1 and the rope density ρ, effectively preventing measurement errors caused by an overturning moment of a bearing base, and thereby correcting the pressure sensor. The on-line detection device is simple in structure, convenient to operate, capable of real-time detection and easy to install, removal of the stabilising ropes is not necessary, measurement is accurate, and signal transmission is convenient. Also disclosed is an on-line detection method for the tension of the suspension ropes (2) or the stabilising ropes (3) in the construction vertical shaft using the on-line detection device. L'invention concerne un dispositif de détection en ligne pour la tension de câbles de suspension (2) ou de câbles de stabilisation (3) dans un arbre vertical de construction, le dispositif étant principalement composé de dispositifs de détection de tension (4) agencés sur des mâts (6) et d'une partie de détection de fréquence de câble d'acier disposée sur la surface d'une ouverture d'arbre. Les dispositifs de détection de tension comprennent principalement des supports de surface inclinés (4-3) fixés sur les mâts (6) de poulies (5), des capteurs de pression (4-2) montés de façon fixe sur des surfaces inclinées des supports de surface inclinés (4-3), et des supports de palier (4-1) reliés de façon fixe aux capteurs de pression (4-2). La partie de détection de fréquence de câble d'acier comprend principalement des dispositifs de détection de fréquence (7) et un collecteur de signal utilisé pour collecter des signaux de fréquence. La fréquence de propagation d'ondes de vibration sur un câble d'acier est détectée périodiquement par l'intermédiaire d'un dispositif de détection de fréquence de câble d'acier (7) disposé sur une plate-forme de couvercle d'arbre (8), et la tension du câble d'acier est obtenue par l'intermédiaire de la longueur de câble d'acier 1 et de la densité de câble ρ, ce qui permet d'empêcher efficacement des erreurs de mesure provoquées par un moment de renversement d'une base de palier, et ce qui permet de corriger le capteur de pression. Le dispositif de détection en ligne a une structure simple, est pratique à utiliser, capable de réaliser une détection en temps réel et facile à installer, le retrait des câbles de stabilisation n'est pas nécessaire, une mesure est précise, et une transmission de signal est pratique. L'invention concerne également un procédé de détection en ligne pour la tension des câbles de suspension (2) ou des câbles de stabilisation (3) dans l'arbre vertical de construction utilisant le dispositif de détection en ligne. 公开了一种施工立井悬吊绳(2)或稳绳(3)张力的在线检测装置,主要由设在井架(6)上的张力检测装置(4)和设在井口地面的钢丝绳频率检测部分构成。张力检测装置主要包括固定在天轮(5)井架(6)上的斜面支座(4-3),固定安装在斜面支座(4-3)斜面上的压力传感器(4-2),以及与压力传感器(4-2)固定连接的轴承支座(4-1)。钢丝绳频率检测部分主要包括频率检测装置(7)以及用于采集频率信号的信号采集器。通过设置在井盖平台(8)上的钢丝绳频率检测装置(7)可定期检测出钢丝绳上振动波的传播频率,通过钢丝绳长l以及绳密度ρ来得到钢丝绳张力,可有效避免因轴承座的倾覆力矩而带来的测量误差,从而对压力传感器进行校正。该在线检测装置结构简单、操作方便、能实时检测,安装简便,无需拆除稳绳,测量精确,信号传输方便。还公开了一种使用该在线检测装置的施工立井悬吊绳(2)或稳绳(3)张力的在线检测方法。
