1.1 This test method specifies the test method for the tensile properties of plastic sheets and films (thickness less than 1.0 mm). Note 1-The film is mandatory defined as a sheet with a rated thickness not greater than 0.25 mm (0.01 in). Note 2—Plastics with a thickness greater than 1 mm ......
Commonly used instruments for measuring wind speed are cup-shaped anemometer, wing-shaped anemometer, catameter, and hot-ball electric anemometer. Wing-shaped and cup-shaped anemometers are easy to use, but their inertia and mechanical friction resistance are large, and are only suitable for measur ......
1. The thermocouple is used to detect the temperature of the original sensing element. Due to the large influence of the installation location and the surrounding air temperature and internal wind flow, the accuracy of the temperature measurement has a large error. The temperature indicator indica ......
Abstract: A derivative-atomic absorption method for the determination of trace elements copper and chromium in fly ash using derivative technology and conventional flame atomic absorption method (FAAS) has been established (D-FAAS). The sensitivity is improved by 15.9 times (cu) and 14.7 times (Cr ......
DNA sequencing is divided into manual sequencing and automatic sequencing. Manual sequencing includes Sanger dideoxy chain termination method and Maxam-Gilbert chemical degradation method. Automated sequencing has actually become the mainstream of today's DNA sequence analysis. American PE ABI ......
