ทางระบายน้ำเพื่อลดแรงดัน : ทางระบายน้ำผิวดินหรือใต้ดิน ใช้ระบายน้ำอยอกจากดินที่อิ่มตัวและมีแรงดันน้ำมากเกินความจำเป็น เรียกอีกอย่างหนึ่งว่า seepage drain
(Environmental Engineering) An acid that does not ionize completely under the conditions of interest. Examples include acetic acid, carbonic acid, and hypochlorous acid. See strong acid.
A powdery substance made by burning, at a high temperature, a mixture of clay and limestone producing lumps called “clinkers” which are ground into a fine powder consisting of hydraulic calcium silicates. For non-portland cements, see aluminous cement.
(Environmental Engineering) Organisms which require molecular oxygen as an electron acceptor for energy production. See anaerobes.
(Environmental Engineering) Organisms which utilize inorganic carbon dioxide for protoplasm synthesis and light for an energy source. See autotrophic and chemoautotrophic.
การซึมผ่าน, การไหลซึมของน้ำในดิน [โยธา]; การรั่วซึม [สิ่งแวดล้อมน้ำ]
(english) A change in the properties of certain metal and alloys (such as steel) that occurs at ambient or moderately elevated temperatures after a hot working heat treatment or cold working operation. Typical properties impacted are hardness, yield strength, tensile strength, ductility, impact value, formability, magnetic properties, etc. See also Non-aging.
(Environmental Engineering) Organisms which utilize inorganic carbon (carbon dioxide or carbonates) for synthesis and inorganic chemicals for energy. See autotrophic and photoautotrophic.
(Environmental Engineering) Energy production without the benefit of oxygen as a terminal electron acceptor, i.e. oxidation in which the net effect is one organic compound oxidizing another. See respiration.
