In this paper,the nanometer carbon blacks of high oxygenous functional groups were used for carrier of target antitumor medicine,it was studied that the nanometer carbon black was oxidized by two ways and that the oxidized carbon black was used to graft antitumour etoposide(VP-16) by two ways also.

本文以高含氧官能团的纳米炭黑为抗肿瘤靶向药物的载体，研究了纳米炭黑的两种氧化改性方法以及在改性后的纳米炭黑表面接枝抗肿瘤药物依托泊苷(VP-16)的两条合成路线。

From FT-IR we think that the hydrogen bond between the polar oxygenous group on the thin film surface treated with plasma and acetone molecules would enlarge the distance between the carbon black particles, resulting in the addition of the electrical resistance, then the response behavior of the thin film to acetone was improved greatly.

我们通过FT-IR研究认为，等离子体处理后，薄膜表面引进的极性含氧基团与丙酮分子之间氢键的形成会增大炭黑粒子之间的距离，导致了薄膜电阻的极大增加，使薄膜对丙酮蒸气的响应得到很大改善。

In order to solve these problems, first, activated carbon which was deashed by hydrochloride was modified through using concentrated sulfuric acid, concentrated nitric acid, hydrogen peroxide and potassium permanganate in the paper, the result showed that the modification of activated carbon is best through using concentrated sulfuric acid under 250℃ through analyzing the desulfurization efficiency and acidic oxygenous group on surface.

对上述问题，本文首先采用浓硫酸、浓硝酸、双氧水和高锰酸钾等氧化剂对盐酸脱灰后的活性炭进行化学改性，通过对改性活性炭的脱硫效果及其表面酸性含氧基团分析，得出在250℃的温度下采用浓硫酸改性活性炭效果最好。

Methods Twelve patients (12 eyes) with sever symblepharon and pseudo-pterygium were treated for symblepharon resection, then autologous oral mucosa was transplanted for reconstruction of the palpebral conjunctiva and fonix, amniotic membrane and conjunctival limbal grafts for bulbar conjunctiva and corneal surface reconstruction.

It was shown that the 5% perchloric acid and 20 Adm^2 current density were good to electropolishing of the titanium alloy.

抛光后的钛合金表面形貌观察结果表明：在高氯酸含量较低(5%)的溶液中以20 Adm^(-2)电流密度抛光可以取得较理想的效果。

The chilling injury and physiological responses of beated and non-heated kidney bean (Phaseolus vulgaris L.) were compared.

采后热处理可有效降低菜豆过氧化物酶的活性，抑制菜豆贮藏过程中表面锈斑的发生。

Root,immunoassay of ELISA(enzyme linked immunosorbent assay) was employed to determine IAA concentration in root tip, unilateral application of agar block containing IAA on root tip was carried out to investigate the effect of exogenous IAA on phototropic response.

为了研究生长素在水稻根负向光性反应中的作用，用含有IAA的琼脂块贴附在种子根的根尖表面观测IAA对根的生长效应，用ELISA法测定根尖的IAA含量，并对种子根弯曲部分进行半薄切片，结果表明：(1)种子根的生长方向既受光的调控也受外施的IAA的调控，根尖向贴有含IAA琼脂块的一侧弯曲生长；(2 )不定根在光照 1.5h后，背光侧的IAA含量明显大于向光侧；(3)种子根尖发生弯曲生长是伸长区的细胞不均等生长所致。

In this paper, we do a preliminary test of the 18 crown - picric acid system, the impact of extraction of strontium, resulting in a variety of conditions can not be made better extraction results.
