Property Fields(1)In INSPEC a numeric search for a specific set of physical properties (/PHP) is available within the text fields(TI, AB). The numeric values are not displayed as single fields but highlighted within the hit displays.
EXPAND in the PHP field (e.g., = > E A/PHP) to see all available physical properties. A search with therespective field codes will be carried out in all database fields with English text. The /PHP index contains acomplete list of codes and related text for all physical properties available for numeric search.

The classifications, validity and catchwords for the main headings and subheadings from the current (8th)edition of the WIPO International Patent Classification (IPC) manual are available. The classifications from theprevious editions (1-7) are also available as separate thesauri. To EXPAND and SEARCH in the thesauri foreditions 1-8, use the field code followed by the edition number, e.g., /IPC2 for the 2nd edition. Catchwords areincluded only in the thesauri for the 8th, 7th, 6th, and 5th editions.

(1) HIT may be used to restrict terms extracted to terms that match the search expression used to create the answer set, e.g., SEL HIT TI.
(2) SELECT HIT and ANALYZE HIT are not valid with this field.
(3) SELECT CIT or ANALYZE CIT allows you to extract the reference from the source documents in this file and have them automaticallyconverted to a citation format for searching in the SCISEARCH file. SEL or ANALYZE CIT extracts first author, publication year,
volume, first page, with a truncation symbol and with /RE appended to the terms created by SELECT.

The suggestion that pitch blende contains some substance more active
than uranium (see Abstract Number 1898A01224) has been followed up andfound to be true. It is present in the sulphides precipitated bysulphuretted hydrogen from an acid solution of pitch blende, and is soin company with lead, bismuth, copper, arsenic, and antimony. Sulphideof ammonium removes the arsenic and the antimony, nitric acid dissolves
the remaining sulphides, and sulphuric acid removes the lead; thesulphate of lead should be well washed with dilute sulphuric acid inorder to recover the portion of the element sought for, which is carried
down by the precipitate. There remains in solution the new element, withbismuth and copper: ammonia in excess precipitates the two former. No
good method has been found for completely separating these by wet
methods, but the two sulphides have different volatilities, and whensublimed in a vacuum tube condense at different parts of the tube. The
ultimate product is a sulphide 400 times as active as uranium, andappears to be that of a new metal, analytically related to bismuth: name

and tantalum, which present merely innumerable very fine lines,
difficult to recognise.

To study the change mechanism and the control of the variable cycle
engine in the process of modal transition, a variable cycle engine model
based on component level characteristics is established. The
two-dimensional CFD technology is used to simulate the influence of mode
selection valve rotation on the engine flow field, which improves theaccuracy of the model. Furthermore, the constant flow control plan is
proposed in the modal transition process to reduce the engine installed
drag. The constant flow control plan adopts the augmentation linear
quadratic regulator control method. Simulation results indicate that thecontrol method is able to effectively control the bypass ratio anddemand flow of the variable cycle engine, and make the engine transformsmoothly, which ensures the stable operation of the engine in modaltransition and the constant demand flow of the engine.
