bán thấm

Friendly

The Vietnamese term "bán thấm" refers to a "semi-permeable" state, especially in the context of physical sciences. It describes a material or membrane that allows certain substances to pass through while blocking others. This concept is commonly used in biology and chemistry, particularly when discussing processes like osmosis.

Basic Explanation:

• Meaning: "Bán thấm" means that something is semi-permeable, which means it can let some particles move through but not all. Think of it like a filter that only allows certain things to pass while keeping others out.

Usage Instructions:

• You usually use "bán thấm" when you are talking about membranes in scientific contexts, like in experiments or natural processes in cells.

Example:

• "Màng tế bào là một ví dụ về màng bán thấm." (The cell membrane is an example of a semi-permeable membrane.)

Advanced Usage:

• In more complex discussions, you might encounter "bán thấm" in topics related to osmosis, where water moves through a semi-permeable membrane from an area of low solute concentration to an area of high solute concentration.

Word Variants:

• There aren't many direct variants of "bán thấm," but you can find related terms:
  • "thấm" means "permeable."
  • "không thấm" means "impermeable," which is the opposite of "bán thấm."

Different Meanings:

• While "bán thấm" mainly relates to physical membranes, in a broader sense, it can be used metaphorically in discussions about filtering ideas or concepts.

Synonyms:

• "màng bán thấm" (semi-permeable membrane) is a direct synonym.
• "màng thấm chọn lọc" (selectively permeable membrane) can be used in some contexts, as it emphasizes the selectivity aspect of the permeability.
