Methods Blood samples were obtained from 5 patients with AIDS, the C2~C3 region of HIV-1 envelope gene was amplified by nested polymerse chain reaction from plasma of each patient, and then subject to sequencing, clonal-quasispecies analysis, and the accumulation of synonymous and nonsynonymous substitutions as well as ds/dn ratios were calculated.

采用套式聚合酶链反应方法对5例艾滋病患者血浆HIV-1 env基因C2~V3区进行PCR扩增，产物经纯化后克隆至pMD-18T载体中，每例患者分别挑取5~8个克隆，共34株，完成阳性克隆的鉴定、抽提纯化和测序，将获得的DNA序列及核苷酸序列进行分析，并计算其核苷酸同源替换率与非同源替换率的比值。

采用巢式PCR方法对5例艾滋病患者血浆HIV-1env基因C2~V3区进行PCR扩增，产物经纯化后克隆至pMD-18T载体中，每例患者分别挑取5~8个克隆，共34株，完成阳性克隆的鉴定、抽提纯化和测序，将获得的DNA序列及氨基酸序列进行分析，并计算其氨基酸同源替换率与非同源替换率的比值。

Since there is no interference by DS anions in the AL-M system, most of the ethoxy groups of APS seem to form oxane bonds with hydroxyl groups.

由于没有干涉德尚阴离子在Al - M系统，大多数乙氧基组黄芪多糖似乎形式oxane债券羟基。

Metho ds: Forty patients without pancreatic and peripancreatic diseases were randomly divided into two groups.

40例无胰腺及胰周疾病的患者随机分2组：①A组准直器1.00mm，1.25mm重建；②B组准直器2.50mm，3.00mm重建。

PH potentiometric titration results show that products with high DS have excellent water solubility in wide pH range.

采用元素分析法确定了产物的取代度，并用FTIR、H〓NMR和X-ray等手段对产物进行了表征。pH滴定表明，较高取代度的样品在宽广的范围内具有良好的水溶性。

Results: DS participants had a larger ROMPx (p.05) and a smaller ROMPy (p.05) than those in normal participants (Px: 0.06±0.02m, Py: 0.12±0.03m).

结果：唐氏症个案COP左右偏移范围较正常个案大（p.05），而COP前后偏移范围却较小（p.05）。

Daniel Scharf reports from the northern Iraqi city of Irbil.

以下是DS从伊拉克北部城市IRBIL为您带回的报道。

Finally, we present a design of DS packet radio in which only one SAW matched filter is required instead of two. The performance of such system is analysed sketchily.

最后一章提出了一种采用单片声表面波匹配滤波器来实现现直扩分组电台的方案，并对其性能进行了简要的分析。

As shown in table 1, the tol values in the order of 100 indicates the currents were far from convergence .

由表中可以看出， tol ds 中接近100的项远大于使电路收敛的误差容限。

Methods. PSF 1000 analyzer was used to measure retinal image quality for eye of 26 subjects (spherical ranged from –3.00 ~-6.00Ds, astigmatism ranged from –0.75~-3.00Dc) fitted with three forms of full correction in random order : unaided eye, with rigid gas permeable contact lenses and toric soft contact lenses. The modulation transfer function curve was observed, 12 points of the MTF curve ( equivalent 12 points of LogMar VA) was used for analysis. Results.

利用人眼点扩散函数分析系统（PSF-1000）检查和评估26例近视散光患者（年龄18~28岁，球镜–3.00DS~-6.00 DS，角膜散光-0.75DC ~-3.00DC）在裸眼、配戴散光软性角膜接触镜和透氧性硬性角膜接触镜三种全矫状态的光学成像质量，采用26眼屈光介质MTF曲线中的12个点（即分别等同于对数视力表4.0~5.1的12个点）进行比较和统计学分析，为了避免主观误差，三种矫正方式的先后顺序随机选择。
