Troposphere

แปลว่า(Environmental Engineering) The lower atmosphere, from the earth's surface to approximately 12 km. This portion of the earth's atmosphere contains about 95 percent of the atmospheric gases. The temperature gradually declines through this region.

Stratosphere

แปลว่า(Environmental Engineering) The atmosphere from approximately 12 km to 70 km. The temperature of the atmosphere increases in this region.Strong acid

hemisphere

แปลว่าซีกโลกด้านหนึ่ง, ครึ่งโลก nortern hemisphere ซีกโลกเหนือ นับจากเส้นศูนย์สูตรของโลกขึ้นมา southern hemisphere ซีกโลกใต้ นับจากเส้นศูนย์สูตรของโลกลงมา

sub stratosphere

แปลว่าชั้นบรรยากาศของโลกซึ่งอยู่ใต้ชั้น stratosphere

Boron (chemical symbol B)

แปลว่า(english) Element N. 5 of the periodic system. Atomic weight 10.82. It is gray in color, ignites at about 1112 (degrees) F. and burns with a brilliant green flame, but its melting point in a non-oxidizing atmosphere is about 4000 (degrees) F. Boron is used in steel in minute quantities for one purpose only- to increase the hardenability as in case hardening and to increase strength and hardness penetration.

axis of a sphere

แปลว่าเส้นผ่าศูนย์กลางของลูกกลม

Photochemical pollutants

แปลว่า(Environmental Engineering) Chemicals which react photochemically (in the presence of sunlight) to destroy ozone in the stratosphere.

Climatology

แปลว่า(Environmental Engineering) The study of the climate, how the earth's atmosphere performs over long periods of time.

magdeburg hemispheres

แปลว่าเครื่องทดลองความดันของอากาศแบบโลหะ กึ่งทรงกลมสองซีกประกบกัน

planisphere

แปลว่าแผนที่บอกตำแหน่งดาวนพเคราะห์ต่างๆ บนท้องฟ้า

Bright Annealed Wire

แปลว่า(english) Steel wire bright drawn and annealed in controlled non-oxidizing atmosphere so that surface oxidation is reduced to a minimum and the surface remains relatively bright.

Greenhouse gases

แปลว่า(Environmental Engineering) Gases which trap solar radiation. Of the solar energy entering the earth's atmosphere a portion is reflected back and a portion penetrates onto the earth's surface. The portion reflected back from the earth's surface is at a different wavelength that when it entered. Carbon dioxide and other gases, which pass solar radiation, absorb this reflected radiation, increasing the earth's temperature. This is much like a greenhouse, hence the name.
