It is futile to expect a hungry and squalid population to be anything but violent and gross.

期望饥锇和贫穷的居民不狂暴和粗野是无用的。

The copolymers are oxidized with hydrogen peroxide in the presence of osmium tetroxide. It is confirmed by superscript 1H-NMR and FTIR that the double bonds in the molecule chains of the copolymers are fully oxidized, while the segments of polystyrene in the copolymers are kept intact.

采用双氧水在四氧化锇催化下对聚合物分子链进行氧化降解，1H-NMR和FT-IR分析表明共聚物中的双键被全部氧化并发生断裂，而共聚物中聚苯乙烯的链节并未被破坏。

Objective: In cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy arteriolar walls are thickened with destruction of vascular smooth muscle cells and deposits of granular osmiophilic material.

目的：伴有皮层下梗死和脑白质病的常染色体显性遗传性脑动脉病的病理特征是血管损害，首先侵及中-小动脉，以血管平滑肌细胞变性为特征并可见嗜锇酸颗粒物质沉积。

Results By using zinc-iodide-osmium staining, the tubulo-vesicular system of parietal cells of fundic gland was manifested as numerous fibrous structures under HVEM. The nematolysosomes was often demonstrated as branching in shape and anastomosed with each other making a network system in cytoplasm under the visual field of the three dimensional electron microscopy combined with AcPase cytochemistry.

结果高压电镜下显示，锌-碘-锇酸染色方法制备的标本胃底腺壁细胞的微管泡系统呈无数纤维状结构；AcPase结合三维电子显微镜观察显示，线性线粒体在胞质中常呈分支状并互相吻合成网。

Methods Forty rats were randomized into normal control group and FS group. The normal control group was fed with conventional forage. FS group was fed with dry forage mixed with FS powder for 3 months, the preliminary dose of FS was 200 mgkg^(-1)d^(-1) and then increased progressively by l00 mgkg^(-1)d^(-1) to ensure over half of the rats having diarrhea, and the final dose was 2800 mgkg^(-1)d^(-1). The frequency and amplitude of colic slow wave were detected and the changes of myenteric plexus and ICC were observed by zinc iodide -osmic acid staining method.

方法］SD大鼠40只，随机分为2组：正常对照组、番泻叶组（饲以含番泻叶粉的乾饲料，起始剂量为200 mgkg^(-1)d^(-1)，以100 mgkg^(-1)d^(-1)剂量递增，保持对半数以上动物有泻下作用，连续3个月，终剂量为2800 mgkg^(-1)d^(-1)，检测大鼠结肠慢波的频率及振幅，采用碘化锌－锇酸法观察肌间神经丛及ICC变化。

There is a polarized organelle, Golgi complex consisted of several saccules and some vesicles beside the nucleus and there are some osmiophilic bodies beneath the parasite pellicule.

结果表明，配子体是一渐进发育的单核、惰性虫体，其核旁有一个由扁平囊和泡状小体极性排列组成的细胞器———高尔基体，虫体被膜下有嗜锇小体。

In the third chapter, we would concentrate on the photophysical properties of a series of Os complexes bearing isoquinoline-triazolate and isoquinoline-pyrazolate moieties respectively.

第三章的部分提到一系列含有isoquinoline-triazolate和isoquinoline-pyrazolate的锇属错合物。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
