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。 -
Then by means of heterocoagulation and encapsulatin, on controlled condition the superfine powders of caco3 and tio2 were coated with different nonaparticles ps. the composite particles with core / shell structure were prepared by heating the composite particles above the glass transition temperature of ps
然後根據異相凝集-包埋法原理對具有不同表面電性的微米級的caco _ 3和tio _ 2進行包埋復合，制得以無機粒子為核，有機粒子為殼層的包覆型有機?無機復合粒子。 -
Gradua11y advancing or vibrating pkase, plateau and quicidy sporting phase. during this learning process, the out8tanding teacher oniy plays the roies of transforndng culture and science into subjects or curricula then transforming subjects or curricula into the learning activities of students. choosing the superfine teachers of our country as the prototype of c1inica1 and spccialiscd teacher, this dissertation points out the diathesis structure
為了實現培養「臨床專家型」教師的目的，本文以「特級教師」為「臨床專家型」教師的原型，根據現實基礎教育對教師的要求以及基礎教育改革的趨勢，歸納出具有中心趨勢的「臨床專家型」教師的素質結構- - 「臨床專家型」教師的培養目標。 -

The study also shows that the increase of tio2 content lead to the ascent of particle density but had few effects on the pore structure, confirming that superfine tio2 had been successfully entrapped in the regenerated cellulose matrix
研究表明，鈦白粉加量的增加會使基質的密度線性增加，但對基質的孔結構影響不大，說明超細顆粒已被有效地包埋進再生纖維素骨架之中。
