碳质的

The understanding of biogeochemical cycle of hydrogen, oxygen, carbon, nitrogen, and sulfur elements in nature ecosystem have increased substantially in the past two decades owing to the improvement of gas isotope ratio mass spectrometer and the wide application of isotopic studies with these elements.

近20年由於「气相同位素比值质谱仪」的改良和氢、氧、碳、氮和硫等稳定同位素的广泛研究，稳定同位素的研究技术已实质增加我们对於这些元素在自然生態系中生地化循环的瞭解。

Influence of different carbon substrates （acetate, glucose, peptone and fecula） on the formation and characteristics of aerobic granules in Sequencing Batch Reactor is studied.

研究了不同的碳源基质（乙酸钠、葡萄糖、蛋白胨、淀粉）对序批式活性污泥法反应器中形成的好氧颗粒污泥的外观形态和特性的影响。

As Dr Cui explains in a recent issue of Nano Letters, when the ink dries, the nanotubes bind to the mesh of fibres in the fabric (it works for both cotton and polyester), making it conductive.

在最新的《纳米快报》中，崔博士解释道，当墨水干时，碳纳米管会粘附在衣服的纤维上，包括棉质或聚酯的材料，使它附有导电性。

Zak mixed 840 ml of vermiculite with 60 ml of finely ground peat moss in the flask, moistened this substrate with 550 ml of MMN nutrient solution, capped the flask with an inverted glass having a cheesecloth-wrapped cotton plug cemented to the bottom, and autoclaved the assembly for 45-60 min at 120℃.

萨克氏混合840 ml的蛭石与60 ml磨细的泥碳土於烧瓶中作为基质，以550 ml的MMN营养液润湿之，再以纱布包棉花塞黏於玻璃杯倒盖之，并将整组器具於120℃高温高压灭菌45-60分钟。

All the resulted products and key intermediates were characterized with EI-MS, 1H-NMR and 13C-NMR. The combined overall yield of these two compounds was up to 52%. The optimized reaction process is mild, easy to manipulate and control.

通过电子轰击质谱、核磁共振氢谱和碳谱对其产物及关键中间体的结构进行表征。2种含有不饱和侧链异噻唑类化合物的总收率达52%，优化后的合成路线条件温和，操作简单，易于控制。

For example, significant correlation in Zunyi prefecture was found between smoking total scores and total nitrogen, nitrogen to nicotine ratio and nicotine, and between offensive odor and total nitrogen and chloride.

在省级尺度，烟叶化学成分与烟叶品质的关系更为复杂，需用更多的化学成分（碳水化合物、含氮化合物及矿质养分）才能综合反映烟叶的品质，如吸食总分与总氮、糖碱比、氮碱比、磷、镁显著相关，杂气与总氮、糖碱比、氮碱比、磷、镁和还原糖显著相关。

At the prefecture scale, the relationship became complicated between chemical components and leaf quality, and more chemical components were needed to represent leaf quality. For example, significant correlation in Zunyi prefecture was found between smoking total scores with total nitrogen, nitrogen to nicotine ratio and nicotine, and between offensive odor with total nitrogen and chloride.

The leaves soft, fat and elastic, the good; hard and inelastic, not good; The color red-brown and even, the good; uneven, black, carbonized, and putrefied such as mud and leaves not opening, not good quality.

叶质柔软、肥嫩、有弹性的好，叶底硬、无弹性的品质不好；色泽褐红、均匀一致的好，色泽花杂不匀，或发黑、碳化、或腐烂如泥，叶张不开展属品质不好。

No one's quite figured out how they help, but they do know that carbs provide your brain with a source of tryptophan from which it can make the sleep-inducing neurotransmitter serotonin.

还没有人能够明确指出它们是如何产生作用的。但是已经确定碳水化合物能够给你的大脑提供一种帮助睡眠的色氨酸，增加羟色胺神经递质。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
