由DNA顺序推知，linker区编码的氨基酸顺序SerGlnAlaGys可能是新的信号肽酶识别位点；信号肽长度的变化可能以某种方式影响蛋白质的分泌量。

Mean time of EA was (48.6±32.8)ms before onset of the surface QRS. The length of conduction pathway was (2.6±0.9)cm. The ablation catheter mapping showed perfect match in at least 11 of 12 leads at the EX (≥11/12), but not at the EA (≤10/12) with pace mapping during sinus rhythm. Purkinje potentials were mapped at EA and CP in all cases, but only one case at EX, and diastolic potentials were mapped at EA in 2 cases during ILVT. All cases were successfully ablated by area ablation at EA or/and line ablation at CP during sinus rhythm. None suffered a recurrence during (12±6) months follow-up.

6例ILVT周长为（286±38）ms，非接触标测显示4例激动起源位于中间隔，2例位于下间隔，EA较体表QRS波提前约（48.6±32.8）ms，传导径路长约（2.6±0.9）ms.6例病人在窦性心律下消融导管起搏标测12导联QRS形态与ILVT相匹配（≥11/12）处位于EX，而非EA（≤10/12）见正文。6例病人在室性心动过速期间消融导管于EA和CP处标测到PP， 2例于EA标测到DP， 1例于EX标测到PP.6例病人在窦性心律下于ILVT起源部位行片状或/和传导径路作线性消融均获成功，随访（12±6）月，未见复发。

Window period risk is a function of the length of the window period and the frequency of new infections among donors Incidence can be measured among repeat donors by observationOther methods are necessary to measure incidence in first-time donors: if the incidence differs, then overall risk estimates must be adjusted.

窗口期风险是献血者窗口期长度和新发感染频率的作用可在重复献血者中通过观察计算发生率必须采用其他方法检测首次献血者中的发病率：如果发病率不同，那么对整体风险的估计必须加以调整。

The length of time for OHI was longer than 30 minutes when performed by a periodontist.

而由牙周专科医师执行时则口腔卫教时间皆超过三十分钟。

In the investigation of micromagnetism, in-plane magnetoresistance and in-field magnetic force microscopy on a series of permalloy planar wires were performed. Here, the wire length and thickness are kept constant, 20μm and 30nm, respectively. The width of the wire spans from 10 to 0.1μm. The magneto-transport behavior and magnetic configuration are quite different regarding their widths, corresponding to the aspect ratio.

在研究微磁学时，我们以平行膜面磁阻的量测和施加磁场下观察磁区的磁力显微来从事一系列镍铁合金毫微米线的磁矩翻转研究，这一系列毫微米线的线长和厚度分别固定为20微米和30奈米，线宽则由10微米变化至0.1微米，线宽的改变将造成磁电传输行为和磁区结构有截然不同的结果。

The length of the arrow shows the approximate speed in a direction perpendicular to the line of sight.

图中的箭头长度近似的表示在垂直于我们的视线的面上，这三个星系团的速度。

Ovulation can be delayed by a number of factors,such as stress,increased activity or medication,but the length of the luteal phase is usually constant.

不少因素会导致排卵延迟，如压力、体力活动增加或药物，但一般来说黄体期的长度是恒定的。
