查询词典 sulfur

OBJECTIVE, To study the direction, route and num- ber of SLCs and their relationship with SLN after subareolar injection of methylene blue and technetium 99m sulfur colloid （^99m Tc-SC）, and to explore the mechanism of sentinel lymph node biopsies produce false negative results in breast cancer patients and the method to improve the detectable rate, METHODS: ^99m Tc-SC was injected preoperatively, and methylene blue was injected by the same subareo-lar route just after anesthetic induction, and then SLNB was carried out according to SLCs in 93 breast cancer patients.

目的：通过乳晕下联合注射^99m Tc-SC和亚甲蓝，研究前哨淋巴通道的行走方向、途径、数量及其与前哨淋巴结之间的关系，以探讨乳腺癌SLNB出现假阴性的机制，并提出提高其检出率、减少假阴性的方法。

Fourty of them were injected with 1.0 mCi of technetium^99 sulfur colloid at preoperation and 2ml methylene blue dye was injected inoperation in subareolar;radioactive SLNs were identified using a hand-held gamma detector probe,all blue stained SLNs were removed during operation.

其中40例病人术前于乳晕下注射1.0mci的锝^99硫化胶体，术中于乳晕下注射亚甲蓝2ml，同时术中用手握式γ-同位素探测仪确认有放射活性的SLN；行手术解剖法解剖分离出蓝染的SLN。

Results The average recovery of sublimed sulfur was 99.5％,RSD 0.99%.

The anodic behavior of electrolytic nickel anode in nickel sulfamate plating Solution was investigated,using anodic polarization curves,metallographic observation of cross-sections of nickel deposits,Hull Cell tests with solutions with and without Cl-,F-,bending tests with five solutions of different compositions,and sulfur content analysis in nickel deposit with mass spectrometry.

采用极化曲线、金相观察、赫尔槽电镀试验、弯曲试验和质谱分析方法，研究了氨基磺酸盐镀镍的阳极行为，证明了当在氨基磺酸盐镀液中使用电解镍阳极时，其活化峰值电流和镀液组成有很大的相关性，当镀液中不含F-和Cl-时其阳极活化峰值电流小，阳极处于极化状态，或相当大面积处于极化状态，使氨基磺酸根在极化的阳极表面氧化，从而使含硫化合物夹附于镀镍层，形成镀层内应力，并使镀层成为层状结构，并出现半光亮的外观。

Bacterial and chemical oxidation of gold-bearing pyrite gives rise to not only ferric sulfate and sulfuric acid but also ferrous sulphate and low-valence oxide of sulfur. The potential in the system is too low to dissolve native gold to form Au(SO4)2- Experiments indicate that gold does not dissolve in sulfatic iron solution.

含金黄铁矿在细菌氧化、化学氧化过程中，除生成高铁的硫酸盐和硫酸外，还生成了亚铁的硫酸盐及硫的低价氧化物，体系中的电位较低，距溶解自然金呈Au(SO_4)_2~-所需电位甚远，实验表明，金不溶于硫酸铁溶液中。
