threshold dose

For a film having a larger value of elasticity modulus, the threshold dose is higher.

弹性模量大的金属薄膜对应的增强附着的阈剂量也大。

Tissue damage is a threshold process, each dose curve can be regarded as the threshold curve, degree of injury increases exponentially with distance attenuation.

组织损伤是阈值过程，每条剂量曲线可被视为阈值曲线，损伤程度随距离的增加呈指数衰减。

AIM: To observe the effect of low dose pirenzepine ( PZP) on the ventricular fibrillation threshold ( VFT) in myocardial ischemia model of rabbits and its mechanism.

目的：观察小剂量哌仑西平对兔急性心肌缺血心室颤动阈值的影响。探讨自主神经作用及其机制。

An Empirical Formula for Calculating Threshold Dose of Film Enhanced Adhesion Induced by Fast Heavy Ion Irradiation

一个计算快重离子辐照引起薄膜附着增强剂量阈值的实验公式

The results indiCated that the shift of threshold voltage of edgeless CMOS/ SOS is almost the same with that of typical CMOS/ SOS for total dose radiation, so is the slope function of log ( I)-V curve.

结果表明，在总剂量辐照下，封闭棚和条形栅CMOS／SOS器件的阈电压及log I－V曲线亚阈斜率的变化趋势基本相同。

The damage constant was calculated, and damage threshold dose φ 0.5 was tested or reckoned.

估算了损伤常数，测试或推算出损伤阈φ0.5；

With codeine phosphate group, at after administration the ointment 0.5h, 3h, 4h the pain threshold of three dose groups were superior improved to codeine group while at the other time point in a considerable improve.

与磷酸可待因组比较，在给药后0.5h、3h、4h不痛膏三个剂量组痛阈提高均优于磷酸可待因组，其他时间点痛阈提高相当。

Besides, the acquisition of other types of raw milk can not achieve the threshold dose of 105 cfu/ mL, can not cause adverse health effects.

除此之外，其他的原料奶收购类型均不能达到105cfu/mL的阈值剂量，不能对人体健康产生不良作用。

The upper threshold dose for crypt cell repair is probably between 10~ 30 Gy.

结肠细胞修复的上限剂量可能在10～30Gy之间。
