The term sic indies "that an incorrect or unusual spelling, phrase, punctuation or meaning in the quote has been reproduced verbatim from the original". As you have not reproduced the quote verbatim – you interpolated (to) – it would be wrong to also add sic.See How do you quote a passage that has used ''[sic]'' mistakenly?, What can I do instead of [sic]?, and The usage of "sic" in
ing a SiC crystal from a solution using the TSSG method. A Si-Ti or Si-Cr alloy solvent material is put in a graphite crucible, and is melted by high frequency induction heating under an atmospheric pressure of helium. Si is supplied from the solvent to the
The paper proposed a method to improve the anti-oxidation performance of carbon fibers (CF) at high temperature environment by coating silicon dioxide (SiO2) and silicon carbide (SiC). The modified sol-gel method had been used to ensure the proper interface between fibers and coating. We used polydimethylsiloxane and ethyl orthosilie to make stable emulsion to uniformly disperse SiC
• Warren suggests that the Stokes and Wilson method of using integral breadths gives an evaluation that is independent of the distribution in size and shape –L is a volume average of the crystal thickness in the direction normal to the reflecting planes

AN1009: Driving MOSFET and IGBT Switches Using the Si828x The Si828x products integrate isolation, gate drivers, fault detection protection, and op-erational indiors into one package to drive IGBTs and MOSFETs as well as other gated power switch devices.
To tailor a reference appliion to your powertrain project, parameterize the components in the reference appliion using data from a domain-specific tool, a test bench, or a vehicle. Depending on your appliion and powertrain configuration, you might need to select the type of component models and further customize the system model.
