However I found e垃圾ide-angle end, and some pincushion distortion at the telephoto end.

图片在ISO调至200时普遍还行，再高的话图象噪点是个问题，在ISO800及以上时尤其严重。

Methods 136 patients with suspected or diagnosed coronary artery disease were studied with 16-slice spiral CT. Choosing left and right coronary artery in the axial enhancement scanning images, previewing 10 images at 0%-100% of the cardiocycle in increments of 10%, We evaluated grade of the image quality and number of the ratable coronary artery in different reconstruction phases. We selected the most clear image of left and right coronary artery, and recorded the phase. Raw data were reconstructed with thin images at the best phase.

对136例临床诊断或拟诊冠心病的患者行16层螺旋CT冠状动脉造影，选取增强扫描R-R心动周期0%~100%的10组图像（间隔10%），评价不同重建时相冠状动脉各主要分支的图像质量等级及可评价冠状动脉数，选择显示最清晰的一组记录时相。

If a person think twice about doing something , had a premonition that will fail, observers can clearly see this; when the spectators are the enemy, he will see more clearly.

三思而后行如果一个人在做某件事时预感到会失败，旁观者会很清楚地看到这一点；当旁观者是敌人时，他会看得更清楚。

It is my belief that much unnecessary perplexity can be avoided if we limit ourselves strictly to the two units, money and labour, when we are dealing with the behaviour of the economic system as a whole; reserving the use of units of particular outputs and equipments to the occasions when we are analysing the output of individual firms or industries in isolation; and the use of vague concepts, such as the quantity of output as a whole, the quantity of capital equipment as a whole and the general level of prices, to the occasions when we are attempting some historical comparison which is within certain limits avowedly unprecise and approximate.

我相信，当我们论述整个经济体系的行为时，如果我们将自己的讨论严格限定于使用两种单位，即货币和劳动，那就可以避免很多不必要的困惑和混乱。当我们孤立地分析单个厂商或单个行业的产出时，可以在这种情形继续使用特定产出和设备的原用单位。当我们试图进行某种历史比较时，可以在这种情形使用诸如总产出数量，总资本设备量和一般价格水平之类含糊不清的概念，这是因为在一定限度内，历史的比较本来就是不精确的和粗略的。

Methods: 5 cases of craniocerebral diseases with secondary hydrocephalus were selected to be monitored by LNP-Ⅰ translumbar epidural space intracranial pressure monitor and LY-Ⅱ ventricular pressure monitor grabually. With horizontal position, we recorded with IVP and ISEDP pressure one time per 5 minutes , The datums of LNP-I monitor in the repeated operations were compared with that of IVP, While variations of clinic symptoms, wave forms of pressure, and intermittent ventriculus dranage in the intracranial hypertension were observed.

选择5例颅脑疾病继发脑积水患者，采用LNP-Ⅰ型经腰硬脊膜外腔颅内压监护仪和LY-Ⅱ型脑室内压监护仪进行持续监测，病人取水平侧卧体位，以每隔5分钟记录IVP和ISEDP压力数据一次，期间多次重复操作LNP-Ⅰ型监护仪与IVP进行对照，同时观察临床症状，压力波形及颅高压时间断行脑室引流时二者变化。

As long as you pay attention to heat dissipation, viscosity increases in winter, water bath heating (material temperature of 50 ° c) will be viscosimetry.

只要注意散热就行了，在冬季粘度增大时，水浴加热50℃时粘度便会迅速下降。

The test bedstand which is composed of electro-motor ,hydraulic pump ,hydraulic motor ,speed verily box and parallel compensating pump, can resolve the problem of power consumption and the power warm while large power hydraulic pump and motor testing.the principle of system is that electro-motor drive the hydraulic pump first,then the pump make the hydraulic motor work through its high pression oil,the follow working hydraulic motor feedback the power in niuju re-drive the hydraulic pump,at last the power is recovered.this bedstand make use of bishi hydraulic system ,which can have a closely construct ,and steadly chuandong ,lower noise ,high power recovery percentage and so on.

本实验台由电动机、油泵、油马达和变速箱以及并联补油泵等一起构成功率反馈实验油路，以解决大功率液压泵及马达在试验时的大功率消耗和能量耗散时的发暖问题。实验台由电动机带动油泵，油泵输出油液驱动液压马达，油马达输出的扭矩通过变速箱传动来回馈给液压泵的输渗入渗出轴，从而实现功率往返收。采用闭式液压系统，结构紧凑、运行平稳、噪声低、功率回收率高；机械补偿，电动机输渗入渗出扭矩经变速箱传动驱动液压泵；液压补偿，并联补油泵对系统的高压油路入行流量补偿。

During the period of the activity of reforming the traditional calendar, Xing Yunlu only reformed the calendar according to the calendar idea established in his book Gujin Lüli Kao (GJLLK, Investigation into Harmonics and Calendrical Astronomy from Antiquity to the Present, c.1600). Combined with the analysis of Xing Yunlu's eclipse records collected from the Mingshilu (True Records of the Ming Dynasty) and Mingshi, we pointed out that Xing Yunlu's had not made ultimate improvement to the traditional calendar in his activity of calendar reform.

结合对邢云路在钦天监参预改历活动中预报日月食记录精度的分析，指出：以邢云路为代表的传统历法家在钦天监进行的历法改革总体来说起色不大，除在个别月食预报以及日食食分的预报结果上好于《授时历》的预报结果外，其他预报结果的精度均不如《授时历》，而且从总体上看邢云路新法的水平还不如当时行用的《大统历》，尤其是邢云路预报天启元年四月朔(1621年5月21日)日食出现差错而宣告了他依据传统历法进行改历努力的失败。

Work, learning task, people have sense of urgency to oneself, often adjust the mood and body, sometimes I didn't work when I would study lie in the window and cany chair, close your eyes, when children often ~~~ of the imagination and emerge, the blue sky, the clean water, white beach, in ways that are constant palm theme ~~~~!

工作、学习的任务多了，人就有紧迫的感觉，常常要自己调整心情和身体，有时我没工作学习时我就会半躺在靠近窗口的藤椅上，闭眼~~年童时常常想象的海边又浮现，蓝色的天空，清澈的海水，白色的沙滩，排成行的棕树，那是不变的主题~~~~！

If it is mainly extrahepatic biliary diffuse stenosis, it will gradually expand upward and downward along bile duct by Bakes biliary duct dilater after the bile duct is cut in surgery ( Including the sphincter of Oddi expansion,the dilatation should be gradual and slow. Too much strength will result in biliary rupture with vascular hemorrhage). T-tube is then placed to support drainage.

若主要是肝外胆管弥漫性狭窄，手术时在切开胆总管之后，以 Bakes 胆道扩张器沿胆管向上、下方向逐步扩张（包括对 Oddi 括约肌的扩张，扩张时应渐次、缓慢的进行，不能过分用力以致胆管破裂及伴行血管出血），然后放置 T 型管支撑引流。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
