On-demand business card printing and membership card is the best way to become an effective solution for your business card printing and membership card, but unfortunately the current price, quality, and ink are changing, many directory have need to die-cutting process, the adoption in the enterprise, and for a more formal way to on-demand business card printing and membership card modes business card printing and membership card catalog production is very small.

按需制卡和会员卡制作是最能成为一种有效的解决方案的制卡和会员卡制作方式，不过遗憾的是目前价格、质量和油墨都在变化，很多目录都改成需要模切工艺的，在企业内采用正规方式，而且以按需制卡和会员卡制作方式制卡和会员卡制作目录的情况很少。

Kuehl's triangle Star-Identification, some improvement had made. With a certain angular and distance tolerance, the separation angle of the observed stars and that of the catalog stars are matched, then, the star triangles are composed in real time. According to the rules of vector rotation, the inconsistent rotation star triangles are removed. After that, put the star triangles with public vertex into star polygon.

Kuehl的三角形星图识别的基础上进行了改进，即在一定角距容差和星对容差范围内和整个导航星角距表进行角距匹配，实时组成星三角，根据矢量法则剔除旋转方向不一致的星三角，把拥有公共顶点的星三角组合成星多边形。

Based on analysis of ISAR imaging theory in detail, the projection image plane is firstly built according to arithmetic imaging model. We can get ideal image, with which we are able to discuss the effects of the ISAR target image with spinning axis during integration time.

在详尽分析了ISAR成像机理的基础上，首先提出了以数学建模的方法建立目标模型的瞬时几何投影像，讨论在相干积累时间内目标等效旋转轴矢量对成像的影响。

Cases recovered completely, and some various complications occurred in 14 cases. Conclusion Harrington rod is an effective internal fixation device for the reduction of fracture and dislocation of vertebra with its longitudinal stress. This device corresponds to the biomechanics of the spinal column. But during the operation, complications should be avoided or diminished by performing strict aseptic technique, bending of the rod to a proper physiological curvature which corresponds to injured spine, doing posterior bone grafting and using corset support after operation.

结论哈氏棒是一种符合生物力学的内固定器材，具有较强的纵向撑开力，能使骨折脱位得到很好复位，但亦具有一些缺点，如术中能做到置钩前预制好骨孔，并将哈氏棒预弯成与伤段脊柱相应的生理弧度，加用钢丝固定双棒，行后路植骨融合，术后使用支架保护，严格无菌操作等，可大大降低并发症的发生。

Increased. In addition, the life of light can also make the blood of unsaturated fatty acid double bond or triple bond was cut, and saturated fatty acids is not easy to be oxidized lipid , a decrease of intravascular lipid deposition, so that the vessel wall smooth, thus reducing atherosclerosis, cataracts, such as cardiovascular disease or the occurrence of eye disease, health promotion plays a good efficacy.

此外，生命光线还可以使血液中不饱和脂肪酸的二重键或三重键被切断，饱和脂肪酸不容易再被氧化成血脂，减少了血管内脂质的沉积，使血管壁光滑，从而减少动脉硬化、白内障等心血管疾病或眼科疾病的发生，对人体健康起着良好的促进功效。

The result was as much a history (in the modern meaning of the word) as a theory, in that Burnet transformed the hypothetical cosmogony and geogony of René Descartes into a sequence of irreversible events, documented by both nature and Scripture.

伯内特把笛卡尔假设的宇宙形成理论和地球形成理论转换成了既由自然界又由圣经记录的一系列不可逆事件，这样，结合的结果既是一种理论，又同样多地是一种历史（& history &的现代意义）。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.
