Methods 520fetuses in24～40weeks were examined by color Doppler echocardiography on four-chamber views and subcostal views to determine CHD.

使用彩色多普勒超声诊断仪随机对520例胎龄24～40周的胎儿，在心脏超声四腔观基础上结合多切面观察胎儿心内结构，以确定胎儿有无先心病。

Objective To investigate clinical significance of color Doppler echocardiographic diagnosis in prenatal diagnosis of fetal congenital heart disease.Methods 520fetuses in24～40weeks were examined by color Doppler echocardiography on four-chamber views and subcostal views to determine CHD.

目的 探讨彩色普勒超声心动图对胎儿先天性心脏病产诊断的临床意义方法使用彩色多普勒超声诊断仪随机对520例胎龄24～40周的胎儿，在心脏超声四腔观基础上结合多切面观察胎儿心内结构，以确定胎儿有无先心病。

The buffer is the power supply of the explode suppresser that is aerogenous automaticly. The equilibrium pressure impacts the burning rate of the propellant in the buffer. And the disperse effect of explosion depressor is affected by burning rate of the propellant. So, the equilibrium pressure impacts the capability of explosion suppresser.

缓冲器作为自产气式抑爆器的动力源，其平衡压力影响着腔内推进剂的燃烧速度，推进剂的燃烧速度决定了抑爆器喷粉效果，从而决定了抑爆器的抑爆能力。

The results suggest that drug synovectomy may be one mechanism about intra-articular corticosteroid therapy in TMD, and this therapy could lead to progressive degradation and destruction of the articular cartilage.

糖皮质激素通过药物性的滑膜切除是治疗TMD关节源性疼痛的一个可能的作用机制；②一次性的关节腔内注射治疗剂量的糖皮质激素可以导致软骨基质的丢失和软骨的破坏。

The radiotherapeutic dose over the whole pelvis was 30Gy to 36Gy by Co 60 unit or 15Mev. Linear Accelerator and further teletherapy with changed portal or brachytherapy of high dose rate (Co 60) followed according to location and size of the recurrence. The total vaginal one-centimeter submucosal dose was 75-80Gy.

治疗方法以放射线治疗为主：使用钴60或15MV光子射线先照射全骨盆腔30至36Gy的剂量；然后再按病灶部位及范围，或改变照野方向和大小继续作远隔治疗，或采用高剂量率腔内近接治疗，使阴道粕膜下1公分处总共接受75至80格雷的剂量。

The influences of additional pressure losses at the entrance and the wall-slip velocity caused by the viscoelasticity of rubber on the process of filling were studied on the basis of injection molding of plastics, and a mathematical model of filling flow in the thin rectangular for rubber was set up.

借鉴塑料熔融注射技术，研究了胶料粘弹性引起的入口附加压力降和固体壁面滑移速度对充模过程的影响，从而建立了橡胶在薄矩形模腔内充模流动的数学模型。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
