摘要： The invention discloses a process for preparing a polynuclear ferric hydroxide-saccharide complex, including: adding an aqueous solution of an alkaline substance drop-wise into an aqueous solution of iron salt at a temperature of 5-20° C. until pH 6-8, collecting the polynuclear ferric hydroxide from the reaction mixture by a conventional method; reacting the polynuclear ferric hydroxide with a saccharide in a solution of an alkaline substance for 10-40 hours at 106-125° C. under pH 10-12, resulting in a crude product having an isoelectric point of 4.4-5.3 and a weight average molecular weight of 20,000-100,000 Daltons, and then harvesting the polynuclear ferric hydroxide-saccharide complex from the crude product. The process can precisely control the molecular weight of the polynuclear ferric hydroxide-saccharide complex without an effect on the other characteristics of the product, for example its saccharide content or isoelectric point etc. Furthermore, it is very simple and readily applicable in industry.

摘要： A computer system includes a chassis and an airflow guiding duct. The chassis includes a chassis bottom wall, a chassis front wall and a chassis rear wall. The chassis front wall defines a first ventilation hole, and the chassis rear wall defines a second ventilation hole. A motherboard is secured to the chassis bottom wall between the chassis front wall and the chassis rear wall. A memory card is secured to the motherboard. The airflow guiding duct is secured in the chassis and includes an entrance portion. The entrance portion covers a portion of the memory card, so as to guide airflow. Airflow flows in the chassis via the first ventilation hole, over the memory card, and then out of the chassis via the second ventilation hole.
