管下的

Here we report that the secreted protein Slit repels neuronal precursors migrating from the anterior subventricular zone in the telencephalon to the olfactory bulb.

在此，我们讲述分泌蛋白裂将自前脑胞室管膜前下区移出的神经元前体细胞，排斥到嗅球。

With a nitrogen purge after treatment at 300℃ the nanotubed titanic acid could not be suit as stationary phase for analysis of hydrocarbons C〓～C〓.

在300℃和N〓气氛下处理以后，纳米管特性完全消失，其不适宜再作为分析C〓～C〓烷烃的固定相。

The treatment of nanotubed titanic acid by heat under vacuum not only can cause the change for crystalline structure d morphology and surface property but also give affection to retention time and peaks symmetry of analytes.

在150℃、-0.1MPa真空下对钛酸纳米管处理以后，其形貌、结构和表面性质均发生变化，并对C〓～C〓烷烃分离的保留时间和色谱峰对称性产生影响。

It is proved that the presented system realizes the high efficiency and accurate control of the screwdown mechanism of the pilger seamless tube mill.

生产实践表明，该控制系统实现了对周期轧管机压下装置高效、准确的控制。

The influences of initial stress on the vibration and transverse wave propagation in carbon nanotubes under ultrahigh frequency (above 1THz) were investigated.

本文研究初始应力对碳纳米管在极高频率(大于1THz)下横波传播的影响。

Join, must both hands hold pipes and pipe fittings tight , keep enough cooling time, cool back hand can unclamp to certain extent , continue and install the next pipe.

连接完毕，必须双手紧握管材和管件，保持足够的冷却时间，冷却到一定程度后手方可松开，继续安装下一段管材。

All told, the three efforts are designed to unglue markets that have seized up as investors have stood on the sidelines.

总而言之，政府此番三管齐下旨在让因投资者离场观望而失灵的市场重新恢复运转。

The positive rates of retrograde ureteropyelography,CT scanning,IVP,ultrasonography were86.7%、50%、12.5%、12.5%respectively.31of40cases were treated by total nephroureterectomy with segmental cystectomy,3cases by segˉmental ureterocystectomy with ureteroneocystostomy,2cases by segmental ureterectomy with end-to-end anastomoˉsis,2cases by single resection of tumor,2cases by resection of residual ureter with segmental cystectomy.

逆行输尿管插管造影、CT、IVP、B超检查的阳性率分别是86.7%、50%、12.5%、12.5%。40例患者中行患肾+全段输尿管+膀胱部分切除术31例，输尿管下段切除术+膀胱吻合术3例，输尿管肿瘤切除+输尿管端端吻合术2例，单纯输尿管肿瘤切除术2例。

The predicted wave patterns of pressure, velocity, density and temperature agree with classical experimental results quite well.

对二维声波谐振管进行了数值模拟，在小振幅下与线性理论的结果符合良好。

Hyperkalemia can occur in several instances, which include (1) excessive potassium intake in patients with a creatinine clearance of less than 20 mL/min,(2) hyporeninemic hypoaldosteronism or type IV renal tubular acidosis in patients with diabetes, urinary obstruction, or interstitial nephritis,(3) significant acidemia, or (4) with drug therapy.

高钾血症可以发生在一些情况下，其中包括：（1）患者钾的摄入量过多与小于20毫升/分钟肌酐清除率，（2）hyporeninemic hypoaldosteronism或肾IV型糖尿病患者肾小管性酸中毒，尿路梗阻，或质肾炎，（3）重大血症，或（4药物治疗）。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
