This paper studies the wearing and tearing function alloy ZL201 enhanced by carborundum grains under both friction of dry and oily lubrications.

王瑾研究了碳化硅颗粒增强ZL201合金复合材料在干摩擦和油润滑摩擦条件下的磨损性能。

Under the oily lubrication, the greater the load and the more content of carborundum, the better the wearing ability of compound material becomes.

在油润滑条件下，载荷越大、碳化硅含量越高，复合材料的耐磨性越优于基体合金。

We observed a first-order reaction for Cr under the conditions that the carboxylate groups are in excess.

在羧基浓度过量的情况下，交联反应对Cr浓度的反应级数是1。

The decrease of P under week light is the result of non-stomatal limitation. The important cause of P decreasing is lower rubisco carboxylation activity.

弱光下辣椒P的下降是非气孔限制的结果，较低的Rubisco羧化活性是辣椒P下降的一个重要原因。

The results showed that under ammonium nutrition there were no significant differences on biomass,leaf area,net photosynthetic rate,carboxylation efficiency of rice plant between water stress and non-water stress.

植物吸收不同形态氮素在能量消耗上的差异，必然导致植物生长以及光合特性的不同。

No carboxylic acid was detected under the experimental conditions.

在实验条件范围内未检测到羧酸副产物。

Reducing afterblowing and using the carburant with low nitrogen content are important measure. The kinetics of nitrogen removal from liquid steel under vacuum with reaction between carbon and oxygen was studied on the multi-function induction furnace. The following conclusions were obtained by experiments: The nitrogen removal was obtained by the nitrogen transfer through the liquid steel diffusion layer at 67Pa and 110Pa pressure, and by the gas-liquid surface chemical reaction at 2000P.

结果表明：真空度对脱氮机理有影响，67Pa～110Pa时脱氮为一级反应，2000Pa时脱氮为二级反应，1340Pa时为混合控制；即使在。1％的条件下，碳氧反应亦可显著提高脱氮速度常数促进深脱氮，在RH内通过加强碳氧反应来提高脱氮率理论上是可行的；当钢液内存在内生或外来固态粒子时，有利于钢液中CO及N〓气泡的形成及排除，这时气泡内p〓≈0，有可能使钢液中氮含量低干与系统真空度平衡的氮含量。

根据帽是一个失谐 bellett GT的引擎，配备有一个单一的化油器仍在设法推动了84匹马力在5200 rpm的，八十九点七英尺/磅。

Results Pulmonary carcinosarcoma and blastoma both were found to be rare malignant tumors, and both epithelial and mesenchymal elements can be seen under the microscopy with different characteristic features.

结果 肺癌肉瘤及肺母细胞瘤均为肺内罕见的恶性肿瘤，镜下均可见上皮及间质两种成分，但又有其不同之处，手术前很难确诊。

Best of all, a single index card can be filed under several subjects and keywords at the same time.

最重要的是，一个单一的指数卡，可以提交下几个主题和关键词在同一时间内。

More direct, directer ; most direct, directest
