Space spraying of Sumithrin in laboratory, the KT_(50) were 7.8 and 4.48 min respectively for mosquitoes and flies and the mortalities of 24 hours were all 100% at 0.16ml/m~3 (including d-phenothrin 4mg/m~3).
Before cutting 25d spraying 0.6% Ca(NO_3)_2 and 0.6% ZnSO_4 could prolong the bottle life span of Rosa 2.57d and 2.7d than the control, and praying 0.4% Ca(NO_3)_2 and 0.4% ZnSO_4 could prolong the bottle life span of Gerbera jamesonii 2.57d and 2.7d than the control.
In spraying and dusting powder experiment, the 7-day's LC_ 50(s) were 3.0418, 0.1623 g/m~2 and 2.8752, 1.1101 g/m~2, respectively, and the 50% shamingdan soluble powder was better than 4% shamingdan granular formulation and 50% WPN.
By using the wrist and the control method, an industrial robot with five degrees of freedom for rapid tooling using metal arc spraying and electric brush plating techniques was developed.
The wrist of the robot including a specially designed link mechanism can maintain the position of the spraying point on the surface of the master pattern whatever the orientation of the gun.
Without the need of any manual programming, the metal arc spraying and brush plating (if necessary) processes can be performed automatically and efficiently after receiving the 3D CAD data of the pattern.
Pre-spray (PS) strategy, which means supplying highly pressurized air into the exhaust manifold two seconds before the accelerating-graph begins to rise and stopping spraying air when the accelerating-graph stops rising.
The development of fruits and accumulation of reserve nutrient substances were synchronized and accelerated after spraying vegetating plants with solutions of studied compounds.
