为了了解有不良孕产史夫妇的染色体断裂率的发生情况,笔者对来河南省人口和计划生育科学技术研究院就诊的有不良孕产史夫妇的染色体断裂率分析的检查结果进行统计学分析。分析结果显示:男性患者的就诊年龄平均为29.07 岁,女性患者的就诊年龄平均为28.15 岁,年龄与染色体检测结果间无相关。男性患者中未发现断裂的占男性总数的32.38 %,女性患者中未发现染色体断裂的占女性总数的37.7 %;男性染色体断裂率为1 的占男性总数的38.11 %,女性染色体断裂率为1 的占女性总数的34.43 %;男性染色体断裂率为2 的占男性总数的21.72 %,女性染色体断裂率为2 的占女性总数的23.36 %;男性染色体断裂率为3 的占男性总数的7.79 %,女性染色体断裂率为3 的占女性总数的2.87 %;女性染色体断裂率为4 的占女性总数的0.82 %;女性染色体断裂率为6 的占女性总数的0.41 %;女性染色体断裂率为9 的占女性总数的0.41 %。男性患者的染色体断裂率均值无差别(P>0.05)。男、女患者的染色体断裂率均值在1.01,患者平均年龄为29.53 岁,经检查有染色体断裂占64.96 %。通过研究发现,染色体断裂率增高可能是引起夫妇中发生胎停、流产、胎儿发育不良等不良孕产现象的重要原因之一。

游离磨料线锯切割是将磨浆中的磨粒通过一定速度的细钢丝线带入切割区域,达到去除工件材料的目的。多股线由多根细金属线绕制而成,表面具有很多凹槽,与钢丝线光滑表面相比,可以输送更多的磨粒进入切割区域,从而提高切割效率。应用0.25 mm的多股线和0.25 mm的钢丝线对光学玻璃K9进行切割对比实验,结果表明,在相同工艺条件下,多股线的切割效率和表面粗糙度均优于钢丝线,但切缝宽度大于钢丝线。

Laser hot wire cladding, with the prominent features of low heat input, high energy efficiency, and high precision, is widely used for remanufacturing metal parts. The cladding process, however, needs to be improved by using a quantitative method. In this work, volumetric defect ratio was proposed as the criterion to describe the integrity of forming quality for cladding layers. Laser deposition experiments with FV520B, one of martensitic stainless steels, were designed by using the Taguchi method. Four process variables, namely, laser power (P), scanning speed (Vs), wire feed rate (Vf), and wire current (I), were optimized based on the analysis of signal-to-noise (S/N) ratio. Metallurgic observation of cladding layer was conducted to compare the forming quality and to validate the analysis method. A stable and continuous process with the optimum parameter combination produced uniform microstructure with minimal defects and cracks, which resulted in a good metallurgical bonding interface.
