It showed that tripoli had a smaller grein size and a greater specific surface. The content of SiO2 was greater than 95%.It is a typical a quartz.

研究表明，粉石英颗粒细小，比表面积大，SiO_2含量大于95％，是一种标准的α-石英，其粒度组成呈现规律性的&双峰态&特征。

A reasonable explanation was given to this phenomenon in terms of the mechanism of anodic dissolution and characteristics of CO〓 corrosion. The corrosion behavior of P110 steel at lower temperature and pressure showed that, the corrosion product film initially was thin and discontinuous, then with the increase of temperature and exposure time it became thicker and sludgy, at last a new crystalline film formed on the sludgy film.

阳极极化和自然腐蚀电位下的EIS谱随温度变化规律表明，在两种电位下，室温到90℃的温度范围内，都存在一个临界温度，低于CT，电化学阻抗谱表现为三个时间常数，高于CT，谱图为双容抗弧，从阳极反应机理和CO〓腐蚀特征出发对试验结果进行了解释。

MRI of IHP has some features. Symmetric high signals on both T1WI and T2WI in basal ganglia, thalami and dentate nucleus have important diagnostic value for IHP.

特发性甲状旁腺功能减退症的颅脑MRI表现具有一定特征性，双侧基底节区、丘脑及齿状核对称短T1稍长T2异常信号具有很高的诊断价值。

The complex characteristics of velocity and water elevation changes at both banks of the curved sections, auto-reassignment of discharges and momentum as well as vortices and super-elevation near the corner of embranchment regions in the furcated channels are displayed. The effects of wetting bed and drying bed are discussed simultaneously.

首次针对180°强弯曲河道、90°双支以及45°三支分叉渠道，数值预报了溃坝波的演进过程，揭示了溃坝波在弯曲河道中内外两岸速度与水位变化，在分叉河道中自动进行流量与动量再分配，在叉点角区形成旋涡、壅高等复杂运动特征，同时反映了湿底与干底的影响。

If our relations are defined by win-win solutions rather than zero-sum rivalries, we will thrive and prosper together.

双方的关系如果以实现双赢而不是互不相容的对抗为特征，我们就能共同繁荣昌盛。

In news video analysis, it has a high probability of emerging anchormen when the key-frame has property of one peak or two peaks, and having detected skin color blocks in key-frame.

在新闻视频分析中，当关键帧中的主色出现单峰或双峰特征，并且检测到肤色区，则出现主持人的概率很大。

Two parameters proposed by RILEM,the critical stress intensity factor K ICS and critical crack tip opening displacement CTOD C ,and third parameter of the characteristic length l ch are applied for investigation of fracture characteristics of concrete,which is with different size of coarse aggregate and different content of silica fume,and under different curring condition.

采用RILEM推荐的双参数临界应力强度因子和临界裂缝尖端张开位移，同时还采用了特征长度lch研究了不同粗骨料粒径、不同硅灰掺量以及不同养护条件下这3个因素对混凝土断裂特性的影响。

The primary purpose of developing the four-tooth difference harmonic drive is to decrease the stress in flexspline under the condition of smaller transmission ratio. In this paper, we focused our study on its accuracy characteristics.

采用四齿差双波谐波齿轮传动的主要目的是为了在小传动比情况下不致影响柔轮的强度，本文主要研究其精度特征。

More risk of PIH seemed to be related to those mothers living in the urban areas with age under 20 or above 35, being peasants and having little educational,having had multiple gestations, conceiving in spring/summer or delivering in winter or spring etc.

在分布特征方面，妊高征年均发病率呈下降趋势，即由1995年的10.7％下降至2000年的8.6％，下降了19.6％；城市、年龄（〈20岁或〉35岁）、农民、低文化程度、双胎、春夏季受孕和冬春季分娩者高发。

Numerical simulations of the model reveal several charaderistic routes to chaos and global scaling behavior in various sones of tWO-parameter space.

模型的数值实验揭示出在双参量空间不同区域中，某些特征性步入混沌的道路和总体标度关系。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
