take the wind out of someone's sails

แปลว่าทำให้รู้สึกอับอาย (คำไม่เป็นทางการ)

wind that blows from north to south in winter

แปลว่าลมว่าว

ไข้หวัด

หมายถึงน. ไข้ที่เป็นในขณะที่เป็นหวัด มีนํ้ามูกและเสมหะมาก บางทีก็ไอด้วย. (อ. common cold, coryza, acute catarrhal rhinitis).

ลมทวนลมค้า

หมายถึงน. ลมชั้นบนที่อยู่เหนือลมค้าในเขตร้อนและพัดสวนทางกับลมค้า. (อ. anti trade wind).

ลมค้า

หมายถึงน. ลมซึ่งพัดออกจากบริเวณความกดอากาศสูงกึ่งโซนร้อนไปยังบริเวณความกดอากาศตํ่าที่เส้นศูนย์สูตร ในซีกโลกเหนือจะพัดมาจากทิศตะวันออกเฉียงเหนือ ส่วนในซีกโลกใต้จะพัดมาจากทิศตะวันออกเฉียงใต้. (อ. trade wind).

Boron Steels

แปลว่า(english) The addition of boron in the range 0.0005-0.005% to certain steels increases the hardenability. A range of boron steels is now listed in the current BS 970 and are widely used for the production of cold headed fastenings.

Band Saw Steel (Wood)

แปลว่า(english) A hardened tempered bright polished high carbon cold rolled spring steel strip produced especially for use in the manufacture of band saws for sawing wood, non ferrous metals, and plastics. Usually carries some nickel and with a Rockwell value of approximately C40/45.

Bridling

แปลว่า(english) The cold working of dead soft annealed strip metal immediately prior to a forming, bending, or drawing operation. A process designed to prevent the formulation of Luder's lines. Caution-Bridled metal should be used promptly and not permitted to (of itself) return to its pre-bridled condition.

Aging 1

แปลว่า(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.

antifreeze

Age Hardening

แปลว่า(english) Hardening by aging, usually after rapid cooling or cold working. The term as applied to soft, or low carbon steels, relates to a wide variety of commercially important, slow, gradual changes that take place in properties of steels after the final treatment. These changes, which bring about a condition of increased hardness, elastic limit, and tensile strength with a consequent loss in ductility, occur during the period in which the steel is at normal temperatures.

Aging 2

แปลว่า(english) A change in properties that occurs at ambient or moderately elevated temperatures after hot working or a heat treating operation (quench aging in ferrous alloys), or after a cold working operation (strain aging). The change in properties is often, but not always, due to a phase change (precipitation), but does not involve a change in chemical composition. In a metal or alloy, a change in properties that generally occurs slowly at room temperature and more rapidly at higher temperatures.
