It was recently reported in Japan that effective component of the extract of Rubia Cordifolia L has obvious inhibition for leukemia, cancer of colon and carcinoma of the lung in mice, its curative effects equaled or exceeded to the catharanthine, mitomycin and adriacin and had less virulence for normal cells.

近来日本学者系川秀治等研究发现茜草提取物中的有效成分环己肽类化合物对小鼠的白血病、腹水癌、大肠癌、肺癌均有明显的抑制作用，其疗效等于或优于长春碱，丝裂霉素、阿霉素，并且对正常细胞的毒性低。

Under the conditions that the concrete expression of its singularities are not sloved,we discuss the bounded property of trajectories, separatrix configuration,nonexistence and existence of limit cycle.

对一类多分子反应模型x＝1－αx－xpyq，y＝βy（xpyq－1－1）进行定性分析，在第一象限奇点无法具体求出的条件下，讨论了轨线的有界性，分界线的位置关系以及极限环的存在性和不存在

经GC-MS分析发现该两细菌对-柠檬烯有显著的生物催化转化作用，能对底物进行不同程度的氧化、还原、水解、酯化、开环等反应，并产生丰富的系列结构不同的其它萜类化合物：包括单萜、倍半萜、二萜、以及三萜等。

Hard to see in the picture but I made damn sure the space between the bearings had plenty of vaseline coated on to prevent epoxy stickage.

努力在图片中看到的，但我所作的可恶肯定之间的空间轴承有足够的凡士林涂层，以防止环氧

The approach can be used in the case where there exist parameter uncertainties, unmodeled dynamics and unknown bounded disturbances.

本文提出的控制方案提高了系统的鲁棒性能，使系统存在不确定性时，仍能保证全局稳定性，使闭环系统的所有信号都是有界的。

The test shows that the butt friction welding process of copper and stainless steel bar can be divided into the following stages approximately: the adhesion at the beginning of friction,friction inside the copper,the expansion of the plastic ring and the friction on the bound surface of copper-stainless steel and the friction in stainless ...

结果表明铜与不锈钢棒料的对接摩擦焊过程大致可分为初始摩擦的粘着；铜内摩擦、塑性环扩展；铜、不锈钢界面摩擦及不锈钢体内摩擦3个主要阶段。在接头形成过程中经历了两次摩擦面的转移。其内容对促进异种材料摩擦焊的接头形成机理研究有积极的作用。

When a fault of the rotor bar of an frequency converter has taken place,the characteristic signal components of the currents will be added into the stator current.

在实际使用中，转子导条断裂是常见的导致变频机故障的重要因素之一，统计表明，大约有10%的故障是由转子断条与端环断裂引起的。

The results show that, the chloride concentrations and diffusion coefficients are both a one-humped function of elevations (can also be the time scale of seawater infiltration), they increase with the increase of elevation until they get to the peak value, and then decrease with the increase of elevation; an evident relationship is being between the surface chloride concentrations and the wave forces acted on the concrete surface, while there is no much difference among the diffusion coefficients; the diffusion coefficients get to bigger as the depth from the concrete surface increase in the influence of the capillary structures evolution and chloride concentration, but this tendency of change was alleviated with the increase of depth.

研究结果表明：氯离子侵蚀混凝土设施的竖向分布规律为氯离子浓度、扩散系数与标高之间同为单峰函数分布，先随高程变大而变大，达到峰值后，随高程变大而减小；氯离子侵蚀混凝土设施的环向分布规律为混凝土构件表面氯离子浓度、氯离子通量与波浪力之间有明显的对应关系，波浪力越大，则表面氯离子浓度和氯离子通量越高，而扩散系数在各方位角差别不明显；由于混凝土长期服役过程中内部毛细孔隙结构演化以及氯离子浓度的影响，氯离子扩散系数随混凝土深度变大而变大，但这种变化趋势随深度逐渐趋缓。

Coral snakes have red, yellow and black rings along the length of their body.
