2) gas composition 气体组成 1. The rational outgassing time was determined by testing the gas compositions of different pouches in the course of storage,and the best garlic sprouts was chosen from these pouches. 以普通聚乙烯袋做对照 ,通过对贮藏过程中各袋内气体组成的测定 ,确定了合理的放风...
The compositions may be enclosed within a gas permeable sachet disposed inside a gas impermeable, sealable container. Some of the compositions utilize an insoluble carbonate to produce carbon dioxide, an oxygen reactive powdered metal to reduce oxygen and a powdered material coated with catalyst to ...
control the environment to keep it as safe as possible and to avoid contaminants in the metal, as a small error can result in structural weaknesses like bubbles or flecks of impurities. Personnel must also monitor the composition of the mixture to make sure it does not enter the danger zone...
(pH = 7.8) under stirring to ensure saturation before tests. With an Alicat gas controller, the flow rate of CO2was controlled at 15 mL/min (standard cm3/min) and routed directly into the gas sampling loop of GC. The gas phase composition was analyzed by GC every 10 min and ...
95% B. The total method runtime was 7 min with a 2-min re-equilibration time between injections. For positive ionization electrospray ionization source conditions, the iFunnel high pressure radiofrequency was set to 150 V, and low pressure set to 60 V. Nebulizer drying gas temperature ...

A chemically modified version of G-CSF (pegfilgastrim) recently was approved for clinical use. With its longer half-life, it can be given once per course of chemotherapy. Both GM-CSF and G-CSF prime PMNs for enhanced phagocytosis and superoxide production in vitro, modulate cell surface ...
A method for forming a pattern reversal film using the composition for forming a pattern reversal film of the present invention is a method including: applying the composition for forming a pattern reversal film onto a substrate; baking at a temperature of 80° C. to 180° C., and forming ...
Referring again to FIG. 1, attritor 50 was described as operating with a hot gas flowing therethrough to reduce moisture content in the solids down to around 35%. An air heater (burner) to achieve this is indicated at 145. In general, the air heater should be a burner that can genera...
The Effect of Shielding Gas Composition on Microstructure and Abrasive Wear Resistance Fabricated with PTA Alloying Technique In this study, SAE 1020 steel surfaces were separately alloyed with preplaced high-carbon-ferro-chromium (FeCr), ferro-molybdenum (FeMo) and ferro-titanium... VV Çay,S ...
