"dropping speed" is correct and usable in written English.
It can be used to describe a situation in which something is slowing down. For example, "The plane started dropping speed as it approached the runway."
With optimized conditions, such as slower dropping speed and suitable concentration of the trisodium citrate, the silver triangles with sharper corner and narrower size distribution will be synthesized.
We selected ethanol as solvent, deionized water as antisolvent, and investigated primarily the type of surfactant and adding amount, drug concentration, volume ratio of antisolvent to solvent, precipitation temperature, dropping speed, stirring speed, stirring time factors affecting drug particles size.
The optimum conditions were: the poloxamer 188 concentration was 0.25%, the drug concentration was 0.08 g/ml, the volume ratio of antisolvent to solvent was 10, the precipitation temperature was 25 °C, the dropping speed was 4 ml/min, the stirring speed was 800 r/min, the stirring time was 5 min.
The optimal preparation conditions for micronized HPC were obtained as follows: dropping speed of 4 mL/min, HPC solution concentration of 0.3 mg/mL, ratio of antisolvent and solvent of 5 mL/mL, precipitation temperature of 10 °C, ultrasonic-stirring time of 14 min, ultrasonic irradiation power of 620 W, and stirring speed of 760 r/min.
The size and shape of the iron oxide NPs depends on the type of salt used (such as chlorides, sulfates, nitrates, perchlorates, etc)., the ferric and ferrous ions ratio, the reaction temperature, the PH value, ionic strength of the media, and the other reaction parameters (e.g. stirring rate, dropping speed of basic solution).
If a proper ball dropping speed is not kept at a constant with each ball drop, it my become tougher to land the ball in a desire hole Be careful, occasionally the sensor that detects what hole the ball drops in may become misaligned, and probably out of sync for a game or two.
Team New Zealand had the lead at the starting line, and then, with the two boats overlapped, used its right of way to force Oracle to drop speed.
It allows for failsafes, better timing, and involvement of mixed hardware and software which may in turn control the object drop, speed of projectile, and so on.
However, although the sea ice is shrinking -- covering less total area as well as becoming thinner -- the Arctic is still a world ruled by ice, a lesson well learned when the Polar Pioneer encountered heavy pack ice between Svalbard and the eastern coast of Greenland, forcing the captain to divert the boat and drop speed to just a few knots.
Upon opening in 1998, The Riddler's Revenge set world records for this type of coaster in height, drop, speed, length and number of inversions.
Upon opening in 1997, it set world records for this type of coaster in height, drop, speed, length and number of inversions.
