碳质的

Nature, most elements have two or more isotopes, the same kinds of elements in the quality of the various isotopes of different, but the types and proportion constant (except for radioactive elements). In 1961, the carbon content of the most abundant in nature, a kind of isotope, carbon-12 atom of a quantity and quality of C as a 12 mass units to it as "benchmarks" for all isotopes of an element according to the average abundance The ratio of the benchmark is the atomic weight of this non-prime, that is listed in the periodic table of atomic weights.

自然界中大多数元素都有两种或更多的同位素，同种元素的各同位素质量不同，但其种类和比例是恒定的。1961年，把碳在自然界含量最丰富的一种同位素，碳12的一个原子的质C量定为12个质量单位，把它作为"基准"，某种元素的所有同位素按丰度的平均值与基准之比，就是这种无素的原子量，即元素周期表列出的原子量。

Lipids are an energy-dense source of fuel calories (~~9kcal/g) compared with proteins and carbohydrates(both ~~4 kcal/g).It is generally recommended in clinical practice that the lipid supply should provide 15-30%of the total calorie intake,or 30-50%of nonprotein calories.

与蛋白和碳水化合物相比，脂肪乳脂质的能量密度更大(≈9 kcal/g比≈4 kcal/g)，所以在临床上普遍推荐脂质供能应占总热量的15-30%，或非蛋白热量的30-50%。

根据气动热力学、传热传质学、N-S方程，分析了战略导弹再入时端头帽烧蚀与碳颗粒的旋转效应，研究结果表明碳颗粒的旋转有利于防热。

The ancient rocks also contained spherical carbonaceous aggregates up to 20 mm diameter, that resemble algae or the cysts of flagellates, and delicate carbonaceous filaments up to 150μ m long.

这些古岩石也包括了球形的碳质聚集物，直径可达20mm 的类似于藻类或鞭毛虫的囊泡，以及脆弱的150微米长的碳丝纤维。

The results show that after quenched and tempered with protective coating,no elements in the protective coating are found to permeate into the matrix,but the martensite laths in welded zone and heat affected zone are refined and the dispersion of carbides in these area is increased,the sizes of the dimples in these fracture are decreased.

通常情况下，D406A钢壳体在热处理中未采用保护气氛，造成调质后壳体表面脱碳严重，使壳体强度降低。为防止或减少调质处理过程脱碳带来的不利影响，可采用保护涂料或保护气氛热处理以及真空热处理等[2]，但对于大型工件，采用保护气氛或真空热处理需要大量的设备资金投入；而采用保护涂料投入较少。

According to this scheme, the Longmaxi Formation is only referred to as the black siliceous and carbonaceous shales at the base of the Silurian strata. All the carbonate rocks above it have been redelineated and redivided into new lithostratigraphic units.

新方案除对志留系底的黑色硅质碳质页岩沿用龙马溪组这一岩石地层单位名称外，其上的碳酸盐岩均重新划分和建立了新的岩石地层单位，并确定其涵义和时限标准。

Is the special production of clay, silica, calcium magnesium fire-resistant Materials, not stereotypes refractories and special refractory professional manufacturers, provinces and cities,"the contract benefits and trustworthy" unit, Green advanced units, clean factories, energy-saving advanced units, not stereotypes of China Institute of industry members of the unit…… no water aluminum company Carbonaceous pressure feed, HFPN-1 mud water cannons, iron-free baking ditch Ramming material at the country "on August 5,""9th Five-Year" in the key technology of the National Science and Technology Progress Award, the company in several years in a row National stereotypes refractories industry is not in the top competitions spears, over the years won the provincial and municipal QC achievement awards, the company and the various tertiary institutions, research centres all close relations of cooperation, to keep professional development trends, the timely development or transplant The latest research results and rapidly transformed into productive forces, the Company is a vigorous, effective high-speed operation of the entity, has been the development of refractories to play an active role.

Most macro-organisms were found in carbonaceous and siliceous mudstones of the upper part of the Neoproterozoic Doushantuo Formation in Jiangkou County, Guizhou Province.

产于贵州江口新元古界陡山沱组上部黑色碳质泥岩和硅质泥岩中的宏体生物群，多数为发育固着器的固着底栖生物。

When surface of TiO2 powder is enveloped by carbon, the reduction is mainly solid-solid reaction between carbon and titanic oxide.

结果表明钛氧化物的还原是逐级进行的，反应过程伴随着相变，当TiO2粉末和C粉末均匀混合时还原碳化反应主要依赖于CO／CO2传质的气固反应，当TiO2颗粒表面被C包膜时主要是碳和钛氧化物之间的固固反应，当TiO2粉末和C粉末混合压球时则两种反应机理均有。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
