Placental location. Uterine morphology are affected late pregnancy in intrauterine fetal position, if the fetus is referred to as the location of abnormal fetal position is not correct, it is the birth of the middle factor does not ring true.

胎盘位置。子宫形态都是影响孕后期胎儿在宫腔内位置的，若胎儿位置异常则称为胎位不正，它才是顺产不顺产的因数呢。

Micro-computer monitors work inside the electron gun to emit electronic, through the acceleration of high-voltage electrode, adjust shooting at the screen, the screen of fluorescent material by high-speed electronic flow impact, resulting in X-ray, scientific evidence shows that more than 20 of each year only Guoqin dose of radiation, will constitute a harm to humans, operate microcomputer year will not be more than 0.3 Roentgen of exposure; even when engaged in computer work for 30 years, the cumulative exposure will not be sufficient to cause human injury lowest half, but during early pregnancy (the first 3 months) the fetus is in a cell division, organ differentiation sensitive period, or should be:(1) hours of work per week is not more than 20 hours (2) one meter away from the computer (3) wearing protective skirt (4) work completed Huanyi bath in order to reduce the electromagnetic radiation on the impact of the fetus.

微电脑显示器工作时，内部的电子枪发射出电子来，经过高压电极的加速，调整射向荧光屏，屏幕上的荧光物质受到高速电子流的撞击，产生X射线，科学论证表明，每年只有超过20论琴的剂量照射，才构成对人体的伤害、操作微机一年也不会超过0.3伦琴的照射量；即使从事微机工作30年，累积的照射量也不足以造成人体损伤最低值的一半，不过妊娠早期(头3个月)胎儿正处于细胞分裂，器官分化的敏感时期，还是应当：(1)每周工作不超过20小时(2)距电脑一米开外(3)穿防护裙(4)工作完毕洗澡换衣，以减少电磁辐射对胎儿的影响。
