Specifically blue light has a marked effect on inflammatory acne lesions and seems sufficient for the treatment of acne. in addition, the combination of blue-red light radiation seems to be superior to blue light alone.

重度痤疮较中度痤疮有更为明显的反应，且副作用很小，使用蓝光对炎症反应可产生效果，配合红光疗效优于单独使用，无明显的副作用。

To avoid this all the hazard properties have to be evaluated before production is allowed. If there is any potential for decomposition, runaway etc. proper measures have to be applied for example to switch from heating to cooling if the temperature rise near the dangerous value.

在生产之前，对所有危险性进行评价，发现有任何分解反应，或反应失控等的可能的危险性因素存在，必须采取有效的措施进行预防，例如如果温度升高到危险值范围内，立即由加热切换到冷却状态。

Based on the assumption that investors react differently to public and private information, we set up a Bivariate Vector Auto-regression Model to examine different responses of value-weighted and equal-weighted stock returns and trading volume from public and private information shocks.

It was found that the conductivity and morphology are greatly influenced by the amount of oxidant,reaction temperature and time,and the kind of dopants.

结果表明，氧化剂用量、反应温度、反应时间、掺杂剂的种类等对最终所得材料的导电性能及结构形态有较大的影响。

The basis of this method is that the temperature variation of an etchant film is induced by the absorption or release of chemical heat during the startup of the reaction.

该方法的实质是利用反应启动时必然有化学热吸收或释放，从而引起材料表面液层温度变化这一特点，通过红外热像实时监测系统，采集液层温度变化过程的红外热像，从而判断反应启动时长。
