防焰器
英文
flame arrester-
Using cd, cu, zn and cr as experimental toxicants and crucian as experimental creature, we employed the environmental biotechniques ( flame atomic absorption spectrophotometry, the method of improved pyrogallol autoxidation and electron microscopy ) to study the acute toxicity and secure concentrations of heavy metals to crucian ; the accumulation and distribution of mixed heavy metals to fingling crucian ; the activities of superoxide dismutase ( sod ) of gill and liver tissues and the hispathological and ultrastructural change of superfine structure of liver and kidney of crucian after cadmium exposure. through which, we intended to fully and systemically study the toxic influence of heavy metals to fish, and preliminarily discuss the influence of heavy metals pollution to the diversified level of fish such as individual, organ, tissue, cell and molecule. thus we tried to provide scientific evidence to establish preventative management measures, avoid and relieve the harm of heavy metals pollution to aquicolous ecosystem in time
隨后以這幾種重金屬作為實驗毒物，以鯽魚為實驗動物，應用環境生物技術、火焰原子吸收分光光度法、鄰苯三酚自氧化法、透射電鏡等技術研究了重金屬cu 、 zn 、 cd和cr對鯽魚的急性毒性及其安全濃度評價、混合重金屬在鯽魚幼體組織內的積累和分佈、 cd對鯽魚鰓和肝臟中sod活性的影響、 cd對鯽魚肝細胞和腎細胞超微結構的影響等，全面和系統地研究了水環境中重金屬暴露對魚類的毒性影響，初步探討了重金屬污染對魚類的個體? ?器官? ?組織? ?細胞? ?分子等各水平層次的影響，為制定漁業生產上預防性的管理措施提供科學依據，及時避免或減輕重金屬污染對水生生態系統造成的損害。In addition, background noise have to be token into account. all these requires that the whole system to have higher anti - interferce properties. by adopting the technology of uv sensor, watchdog and software filters, noise is notably shielded, accordingly the system gains high performance in reliability and stabilization. this is also ensued by its self - examination function which can efficiently avoid error or miss alarm
本系統採用紫外線火焰傳感器作為探測器，結合硬體看門狗及軟體濾波等方法，有效地屏蔽了噪聲的影響；系統穩定可靠，具有自診斷功能，可有效防止誤報和漏報，實現準確報警，並具有豐富的各種顯示和報警功能。Fire - fighting equipment for fire - fighting vehicles ; portable oxygen cutting apparatus
消防車輛用消防裝備.便攜式火焰切割器械Weapon and armor proficiency : pyrokineticists gain no proficiency in any weapon or armor
擅長武器與防具：操焰者不會獲得任何武器或防具擅長。Methods of test for assessment of the fire integrity of electric cables - test for unprotected small cables for use in emergency circuits - bs en 50200 with 930 deg flame and with water spray
電纜著火完整性評定的試驗方法.應急電路中使用的無防護型小型電纜的試驗. bs en 50200外加930 ?火焰和噴水器These measures are as follows : shorten the primary wind intervals to improve thermal load of the burner ; reduce the size of hypothetical circle of contact to prevent the flame from splashing ; use nozzles with larger height / width ratio to increase the effusive rigidity, so as to increase the jet flow depth of secondary wind into the main jet flow ; use a higher primary wind velocity to increase its jet flow rigidity ; use a special flame holder structure of the primary nozzle, so as to improve
這些技術措施主要有:縮小一次風間距以提高燃燒器區域熱負荷;縮小假想切圓防止火焰刷墻;採用高寬比較大的二次風噴口以增加射流剛性，提高二次風射流進入主射流的深度;採用較高的一次風速來提高一次風射流剛性;一次風噴口採用特殊穩燃結構;提高下二次風的托粉能力。分享友人
