Holding Period Period

แปลว่า(Concrete Engineering) In the manufacture of concrete products, the period between completion of casting and the introduction of additional heat or the steam curing period

เสน

หมายถึงน. สารประกอบประเภทออกไซด์ของตะกั่ว มีสูตร Pb3O4 ลักษณะเป็นผงละเอียด สีแดงเข้ม ใช้ประโยชน์ในอุตสาหกรรมทำสีทาและทำแก้ว, ตะกั่วแดง ก็เรียก. (อ. red lead, minium). (ดู ตะกั่วแดง).

Adiabatic Curing

แปลว่า(Concrete Engineering) The maintenance of ambient conditions during the setting and hardening of concrete so that heat is neither lost nor gained from the surroundings of the concrete.

Denitrification

แปลว่า(Environmental Engineering) The anoxic biological conversion of nitrate to nitrogen gas. It occurs naturally in surface waters low in oxygen, and it can be engineered in wastewater treatment systems.

ตะกั่วแดง

หมายถึงน. สารประกอบประเภทออกไซด์ของตะกั่ว มีสูตร Pb3O4 ลักษณะเป็นผงละเอียดสีแดงเข้ม ใช้ประโยชน์ในอุตสาหกรรมทำสีทา และทำแก้ว, เสน ก็เรียก. (อ. red lead, minium).

a long sticky mass like mucus that runs from the nose or silver that drops when it is melted by the heat

แปลว่ายวง

Discrete settling

แปลว่า(Environmental Engineering) Settling in which individual particles settle independently, neither agglomerating or interfering with the settling of the other particles present. This occurs in waters with a low concentration of particles.

Acid-Process

แปลว่า(english) A process of making steel, either Bessemer, open-hearth or electric, in which the furnace is lined with a siliceous refractory and for which low phosphorus pig iron is required as this element is not removed.

Brasses

แปลว่า(english) Copper base alloys in which zinc is the principal alloying element. Brass is harder and mechanically stronger than either of its alloying elements copper or zinc. It is formable and ductile; develops high tensile strength with cold-working and is not heat treatable.

Acid Process 1

แปลว่า(english) A process of making steel, either Bessemer, open-hearth or electric, in which the furnace is lined with a siliceous refractory and for which low phosphorus pig iron is required as this element is not removed.

Colloids

แปลว่า(Environmental Engineering) Small particles which have a negligible settling velocity. These particles have a very small mass so gravitational force is low compared to surface frictional forces. Typical colloidal sizes range from 10-3 mm to 1 mm.

Electronegativity

แปลว่า(Environmental Engineering) The potential of an atom to attract electrons when the atom is bonded in a compound. The scale is 0 to 4 with 0 being the most electropositive (low attraction) and 4 being the most electronegative (high attraction).
