  1. A review with 44 references is given on recent development of heterocyclic azo compounds ' application in spectrophotometric analysis of copper, zinc, and iron in biological sample including three kinds of heterocyclic azo compounds : pyridylazo compound, imidazolylazo compound, and triazolylazo compound

    摘要綜述了近年來應用偶氮類顯色劑測定生物樣品中銅、鋅、鐵的光度分析發展狀況,從吡啶偶氮類試劑、咪唑偶氮類試劑以及三氮唑偶氮類試劑加以歸納,引用文獻44篇。
  2. 281 double crossover mutants were examined by fermentation experiments and hplc analysis for production of polyketides. besides avermectin b1a and b2a, a new compound ( about l ~ 4ug / ml ) which showed a retention time and fragmentation patterns identical to those of the authentic sample of 22, 23 - dihydroavermectin bla by hplc and lc / ms analysis were detected in culture extracts of 27 isolates

    在篩選的281個雙交換突變株中,有27株除了產生阿維菌素b1a和b2a ,還產生一個新組分,經hplc和lc ms分析,證實該組分為c - 22 , 23雙氫阿維菌素b1a (即伊維菌素b1a ) 。
  3. Nowadays, at home and abroad, one of the most widely used methods is judging fish freshness by detecting the compound of decomposed product caused by adenosine triphophate in the fish ’ s tissue in a chemical way. but this method has much shortcoming like manipulating complicatedly, costing highly, consuming much effort and time. and it needs to damage fish sample, so it is difficult to generalize the method in fact

    最常用的魚鮮度檢測方法是通過化學手段測量魚體內三磷酸腺苷分解產物的成分來判斷鮮度,其操作復雜、成本高、費時費力,且需要破壞魚體樣本,難以推廣使用,因此迫切需要利用氣敏傳感器開發一種無損、快速、方便的魚鮮度檢測方法。
  4. The study of phase formation of the polycrystalline la1 - xagxmno a series of polycrystalline la1 - xagxmno3 samples with x range nominally from 0. 05 to 0. 45 were investigated, and found that the critical phase temperature has close relation with the content of silver in the sample. and pointed out in the case of agl + doped in lamno3, when x achieved a fixed value ( x = 0. 15 ), ag would separate out, ag - rich phase appeared, samples became compound phase

    並且當銀含量達到一定程度時會有單質銀析出,我們認為這是因為銀離子在溶膠?凝膠的過程中被還原成單質,以銀團簇的形態存在於樣品中,隨著燒結溫度的提高,銀原子逐漸被氧化成銀離子,取代la ~ ( 3 + ) ,進入晶格,形成鈣鈦礦結構。
