The phrase "a fixed composition" is correct and usable in written English.
It can be used in contexts where you are referring to a specific, unchanging arrangement or structure, often in fields like music, literature, or art.
Example: "The artist's latest work is a fixed composition that showcases her unique style and technique."
Alternatives: "a set arrangement" or "a defined structure".
A phase is a homogeneous substance that has a fixed composition and uniform chemical and physical properties.
The oxidizer has a fixed composition of 75%H2O 25%O2.
So far, most Kalina cycle power plants are designed with a working fluid mixture having a fixed composition, and thus normally operate at a fixed condensing temperature.
All deposited geometries had a fixed composition (68 71 wt.% Pt) and crystalline structure typical of Co-hcp, distorted due to platinum incorporation.
For ternary InxGa1−xAs, the absorption coefficient at a specific composition could be achieved by translating the data from a known composition, whereas it should be careful to translate the absorption coefficients between different temperatures even for a fixed composition.
Extraction transesterification of the pretreated biomass was carried out at 40 °C for 24 h using a reaction systems of a fixed composition (i.e. biomass, hexane, methanol, water and immobilized enzyme).
In this work, a template is formally described by means of a vocabulary of allowed child-object types, a set of relations allowed between those types, rules that constraint the instantiation of these child-object types and relations, and a set of fixed composition's components (media or composite objects and relationships).
On the other hand, HEm at 7.64 MPa and 313.15 and 323.15 K varies linearly with CO2 mole fraction in the two-phase region where a gaseous mixture and a liquid mixture of fixed composition, for a given condition of temperature and pressure, are in equilibrium.
On the other hand, HEm at 9.00 MPa and 323.15 and 333.15 K varies linearly with CO2 mole fraction in the two-phase region where a gaseous and a liquid mixture of fixed composition are in equilibrium.
This graded layer may or may not be capped with a layer of TiCN with fixed composition.
The results show that a composition-adjustable Kalina cycle could achieve higher annual-average thermal efficiency than a conventional one with a fixed mixture composition.
