phân cực kế

Friendly

The Vietnamese word "phân cực kế" translates to "polarimeter" in English. It is a scientific instrument used in the field of physics, particularly in optics and chemistry, to measure the angle of rotation of polarized light as it passes through a substance. This can help determine the concentration of certain substances in a solution or the specific rotation of a material.

Usage Instructions:

• "Phân cực kế" is mainly used in scientific contexts, especially in laboratories or research settings.
• It is not commonly used in everyday conversation.

Example:

• "Trong thí nghiệm, chúng tôi đã sử dụng phân cực kế để đo độ quay của ánh sáng qua dung dịch đường." (In the experiment, we used a polarimeter to measure the rotation of light through a sugar solution.)

Advanced Usage:

• In advanced studies, "phân cực kế" can be discussed in terms of its applications in determining the optical purity of chiral compounds, which are important in pharmaceuticals and organic chemistry.

Word Variants:

• The term can also be referred to as "máy phân cực" (polarizing machine) in some contexts, although this term may refer to related but distinct instruments.

Different Meanings:

• While "phân cực kế" specifically refers to the polarimeter, the components of the word can be broken down:

  • "phân cực" means "polarization."
  • "kế" means "meter" or "device for measuring."

Synonyms:

• There are no direct synonyms for "phân cực kế," but related terms include:
  • "thiết bị đo ánh sáng" (light measuring device)
  • "máy đo độ quay" (rotation measuring device) – though these terms are more general and may refer to different types of instruments.
