摘要： In a method for detecting the operational readiness of a jump lambda sensor associated with an internal combustion engine the internal resistance of the sensor is determined as the criterion for the operational readiness of the sensor. The internal resistance is measured by applying a pulsed current to the sensor, the frequency of the current being selected as a function of the state of the sensor (1, 2, 3, 4).

摘要： A multiple resonance sample coil for a magic angle spinning nuclear magnetic resonance probe is comprised of a solenoid coil that resonates at low frequencies and a resonator that resonates at high frequencies. The ends of the low frequency solenoid coil are electrically connected to the high frequency resonator to eliminate arcing and allow the solenoid coil to extend the full width of the resonator. In some embodiments, the high frequency resonator is constructed from the outermost turns of the solenoid coil in the form of a birdcage resonator. In another embodiment, the solenoid coil is electrically connected to one turn of the resonator and the other turn is used as part of a trap to shunt the resonator at low frequencies.

摘要： A sample vessel (80) made of material with magnetic susceptibility χ2, for containing a sample substance (87) with magnetic susceptibility χ3≠χ2 to be analyzed in a nuclear magnetic resonance (NMR) spectrometer, has an inner interface G2 toward the sample substance and an outer interface G1 toward the environment (85) that exhibits magnetic susceptibility χ1. The shape of the interface toward the sample substance and the interface toward the environment are coordinated to match the discontinuities in susceptibility at the interfaces in such a way that on introduction of the sample tube filled with sample substance into the previously homogeneous magnetic field of an NMR spectrometer, the magnetic field inside the sample substance remains largely homogeneous.

摘要： A method for homogenizing a static magnetic field with a magnetic field distribution B0(r) for nuclear magnetic resonance spectroscopy by adjusting the currents Ci through the shim coils, thus creating spatial field distributions Ci·Si(r), where r stands for one, two, or three of the spatial dimensions x, y, and z, and said magnetic field distribution B0(r) has only a field component along z, in a working volume of a magnetic resonance apparatus with one or more radio frequency (=RF) coils (5) for inducing RF pulses and receiving RF signals within a working volume, said RF coils having a spatial sensitivity distribution of magnitudes B1k(r), and with shim coils (6) for homogenizing the magnetic field within the working volume, said shim coils (6) being characterized by their magnetic field distributions per unit current Si(r) and having components only along z, includes the following steps: (a) Mapping the magnetic field distribution B0(r) of the main magnetic field, (b) calculating a simulated spectrum IS(f) based on the sum of the magnetic field distribution B0(r) and the additional field distributions Ci·Si(r) generated by the shim coils (6), and on the sensitivity distributions B1k(r) of the RF coils(5), (c) optimising a quality criterion derived from the simulated spectrum IS(f) by using an optimisation procedure within a search range with the shim currents Ci as a set of parameters, whereby for each new set of parameter values step (b) has to be repeated, (d) realising the found optimum of the quality criterion of step (c) by generating the associated target field distribution B0T(r). In this way a direct one-to-one link is obtained between a set of shim currents and the associated NMR spectrum The quality of the desired NMR spectra can be improved with this method.

摘要： A device for centering an elongated sample tube (8), filled with a measuring substance, relative to a vertical axis of a nuclear magnetic resonance (NMR) receiver coil system (9) which is rigidly mounted in a support device is characterized in that at least two centering means are provided which are mutually separated in an axial direction of the receiver coil axis and act exclusively in a radial direction on the sample tube (8), one of which is disposed in the upper region (9a) and the other in the lower region (9b, 9b′) of the NMR receiver coil system (9a-k) and with at least one positioning means acting on the sample tube (8) in an exclusively axial direction which may be located either below (20a) or above (17) the NMR receiver coil system, wherein the exclusively radially acting centering means (9a, 9b, 9b′) are components of the NMR receiver coil system (9a-k). The centering accuracy can be increased compared to known devices to obtain optimum results even for sample tubes in the form of measuring capillaries which pose the highest requirements with respect to centering accuracy.

摘要： A method and device for correcting a voltage-lambda characteristic curve of a two-step lambda oxygen sensor in an exhaust tract relative to a reference-voltage lambda characteristic curve of the oxygen sensor; a deviation in the characteristic curve relative to the reference characteristic curve at lambda=1 being corrected; based on a value pair on the reference-voltage lambda characteristic curve, the composition of the air-fuel mixture supplied to the engine being changed toward lambda=1; the actual value of lambda being inferred from the change in the composition of the air-fuel mixture. The adaptation of the operating parameters of the oxygen sensor is intended to eliminate the cause of a deviation. Efforts are not merely directed to adapting the deviation to the reference characteristic curve by shifting the voltage-lambda characteristic curve. Effects, which may lead to tolerance- or aging-induced falsifications of the voltage-lambda characteristic curve, can be fully compensated.

摘要： The invention relates to a method and device for diagnosing deviations in a single cylinder lambda control in an internal combustion engine having at least two cylinders and an exhaust gas sensor designed as a broadband lambda sensor, wherein a pump current is evaluated by means of a pump cell and the pump current is used at least temporarily for an individual cylinder lambda control. According to the invention, a pump voltage or a pump voltage change is determined via the pump cell in addition to the pump current and the value is transmitted to a diagnosis apparatus. Deviations in the single cylinder lambda control can thus be better diagnosed without additional material expense according to the invention, which provides advantages in particular in respect of tightened rulemaking in on-board diagnosis. A preferred application of the method is the use in internal combustion engines having multi-bank exhaust systems.

摘要： A monitoring cell, used to perform a measurement in an NMR spectrometer of a reaction fluid produced by a reaction vessel, has a body having inlet and outlet transport coaxial capillaries for transporting the reaction fluid between the body and the reaction vessel. Cooling lines are also positioned coaxially with the transport capillaries to transport cooling liquid between the body and the reaction vessel. The cell further has a hollow sample probe for insertion into the NMR spectrometer and a coupler section that removably connects the sample probe to the body so that the inlet transport capillary extends through the body into the interior of the sample probe and the outlet transport capillary is sealed to the sample probe to allow reaction fluid that enters the sample probe via the inlet transport capillary to exit the sample probe via the outlet transport capillary.
