1·To study the correlation of the power output, exposure duration and tissue temperature.

通过体外测温初步探讨微波凝固输出功率及辐射时间与组织温度的关系。

2·The principle of exposure duration calibration is formed by adjusting exposure duration and keeping other parameters of digital color camera.

仅改变曝光时间，保持相机的其它参数不变，建立了曝光标定原理。

3·Objective: This study evaluated the micro-hardness of light-cured composite resin of different light sources, materials , exposure duration time and depth.

目的：探讨不同条件及不同厚度下光敏复合树脂的显微硬度。

4·Besides acute exposure of large dose, there are repeated exposures mainly in which exposure duration is unequal and dose levels heterogeneous, even exposure may continue for a couple of days.

辐射事故照射，除大剂量急性照射情况外，更多的还有受照延续时间不等、照射水平不一的多次受照情况，甚至尚有数天内连续受照的。

5·The results of numerical simulation show the lesion of photoaging skin can be selectively damaged if the wavelength, exposure duration and exposure dose of irradiated ligh are reasonably selected.

数值模拟的结果表明：合理选择光辐射波长、辐射曝光时间和曝光剂量，可以选择性的热破坏光老化皮肤中的病损组织。

6·Exposure to loud noises can definitely produce a partial or complete loss of hearing, depending on the intensity, duration, and frequency composition of the noise.

暴露在巨大的噪音中肯定会造成部分或完全的听力丧失，这取决于噪音的强度、持续时间和频率组成。

7·It limits the duration of your exposure and keeps the phone farther away from your head and body.

这样会限制你接触手机的持续时间，使手机远离你的头部和身体。

8·But no evidence demonstrates that the duration of outdoor exposure - in places where people can move freely about - is long enough to cause substantial health damage.

但还没有证据表明，当人在户外自由移动时，身体接触到的烟气的残余，确实多得能够伤害健康。

9·Sunscreen should never be used to prolong the duration of sun exposure.

绝不将防晒霜用于延长暴露于太阳的时间。

10·The severity and duration of the trauma, the victim's age, their support system, previous exposure to trauma, and otherfactors will determine the severity and outcome of these symptoms.

创伤的严重性与持续性、幸存者的年龄、他们的支持系统、之前暴露于创伤中的经历，以及其他因素都将决定这些症状的严重性与后果。
