A snake in the grass is particularly dangerous because it is difficult to discover.

藏在草中的蛇特别危险，因为不易发现。

The strong man who in the confidence of sturdy health courts the sternest activities of life and rejoices in the hardihood of constant labor may still have lurking near his vitals the unheeded disease that dooms him to sudden collapse.

即使一个强壮的人，具有坚强的体魄，对生活有坚定而积极的追求，并敢于承受持久的劳动，也可能存在潜在的、不易发现的致命的疾病，从而使他突然倒下。

Result: In 489 rut CT natural cases discover lacuna-focus. In no-easy diagnostic shadiness lacuna-focus 502 cases, using HRCT diagnosed in deed 300 lacuna- focus ,bogus lacuna-focus 202 cases, at one time discover HRCT of up to snuff brain -organise-configurable show then rut CT preponderance.

结果：有489例常规CT正常的病例中发现了腔隙灶，在遇到的502例不易诊断的可疑病灶中，经HRCT确诊的真正腔隙灶300例，伪腔隙202例，同时发现HRCT对正常脑组织结构的显示要较常规CT优越得多。

After analysing the parallelization of DSMC method,it's found that DSMC method is not easy to be parallelized.

对DSMC方法进行并行化分析，发现其属于不易并行的方法。

This will enable those who do not easily found in long-tail keywords get better in the rankings.

这样做，可以使那些根本不易发现的长尾关键词得到较好的的排名。

Results: l、The optimal scan parameters for chinese people are flow rate of 3. 0 mL/sec and total injection 125ml. 2、Visibility of coronary arteries and segments: only those proximal and mid segment is image quality sufficient to allow a semiquantitative assessment. 3、Detection of Atherosclerotic Plaque: CT coronary imaging revealed highest sensitivities for the detection of atherosclerotic wall changes the sensitivity of stenoses was 86. 3％. 4、MSCT coronary angiography is easy to prove the entire anatomic structure of coronary and it is an effective technique for evaluating coronary patency. 5、MSCT coronary angiography correctly identified all normal controls and all patients with coronary artery fistula. The anatomic course of the coronary artery fistula was correctly classified. 6、A11 severe lesion could be visualised by

结果：1、不同的扫描技术参数所获得的造影图像质量不同，注射速率3.0ml/s组以及125m1对比剂总量组比较适合国内患者。2、多层螺旋CT冠状动脉造影可显示冠状动脉的主要分支，尤其是冠状动脉的近、中段，显示率在90％以上。3、多层螺旋CT冠状动脉造影对狭窄病变的敏感性为87.3％，能检出冠状动脉造影不易发现的细小斑块，判断狭窄的原因及斑块的特征。4、多层螺旋CT冠状动脉造影可显示搭桥血管的形态、位置及通畅程度，显示桥血管及支架的内腔，安全便捷。5、多层螺旋CT显示冠状动脉畸形准确性高（3/3），多种成像方法可弥补冠状动脉造影显示的不足。6、仿真内窥镜可显示冠状动脉内膜和内腔，显示狭窄斑块的性质。
