We aimed to solved the problem of the low efficiency and low mineralization of the treatment of photocatalysis or photosensitization alone and set up a theoretical model and a practical technic flow for the efficient degradation of pollutants under solar irradaition.

解决光催化与光敏化长期长期分离处理的低效和矿化不彻底的难题，为利用太阳光高效降解污染物提供理论模型和切实可行的工艺流程。

The R effect on time-dependent phototropism was further studied by characterizing its fluence-response relationship. The results showed the R effect was a low-fluence-response, unlike those on pulse-induced phototropisms that show a very-low-fluence-response mode.

本研究进一步分析了红光对蓝光照射时间依赖型向光性影响的光量反应曲线，发现该反应不像红光对脉冲蓝光诱导的向光性的影响那样属于超低光量反应，而是一种低光量反应，且之后的脉冲远红光可以逆转红光对TDP影响的效果。

After moving into ICU, former diseases,invasive testings and treatments, daily nursing, long-term immobilization can causepain to the patient; continuous noisy, continuous surrounding light, various stimuli,sleep disturbances, worry about his own disease can cause anxiety to the patient;extreme anxiety, pain, phrenitis, side effects of drugs or interaction of drugs, anoxia,low blood pressure, low blood glucose, drug or alcohol withdrawal response cancause mania, which all can result in strong stress response, human-machine resist,removal of devices and canals involuntarily.

病人进入ICU后可因原发疾病、侵入性检查与治疗、日常护理、长期制动等因素导致疼痛；可因持续噪音、持续的周围灯光、各种刺激、睡眠干扰、对自身疾病的担心等因素导致焦虑；还可因极度焦虑、疼痛、谵妄，药物的副作用或相互作用，缺氧、低血压、低血糖等生理紊乱，酒精或药物的戒断反应等因素导致躁动。

The microbial production of AD had the advantage of high purity, low cost and short cycle time, but it was restricted by the conversion ability of microbes and low solubility of phytosterol.

微生物法制取AD具有产品纯度高、生产成本低、周期短等特点，但也存在菌种转化能力普遍不高，底物甾醇在水中溶解度低等缺点。

So Garner, his student Fabian Fernandez, and their colleagues gae their mice either low doses of PTZ mixed with milk, or low-dose injections of picrotoxin or bilobalide, daily for two to four weeks to slightly raise the leel of excitation in the brain.

因此Garner，他的学生Fabian Fernandez，及他们同事为实验老鼠提供低剂量的戊四氮和牛奶混合或者低剂量的印防己毒提高大脑兴奋度。

Not only is sound pressure low, but the frequency is very low in pitch.

不仅是声音压力较低，但频率是非常低的音调。

The inention relates to a radio wave absorber which can achieve low cost, a small transportation volume, an excellent radio wave absorbing characteristic from a low frequency to a high frequency with a short length, a small or no difference in the characteristic of a polarization plane, and can be easily fabricated and worked.

本发明涉及一种电波吸收件、电波吸收体及其制造方法、以及电波暗室，用于实现下述的电波吸收体，其成本低、输送体积小、长度短、从低频到高频能获得良好的电波吸收特性，没有极化面特性差或该极化面特性差较小、重量轻、结构强度高、制造和施工容易。

Talc has a platy structure with hydrophobic surfaces. There is weak cohesion between the crystal lattices within talc particles; hence it possesses the advantages of a very low frictional coefficient, softness, and low abrasiveness.

滑石粉为片状结构，具有表面疏水性、在滑石粉颗粒中，晶格层间的内聚力较低、具非常低的摩擦系数、柔软性、低磨擦性等优点。

The microstrip antennas has the volume small, the weight light, the structure stable, the section plane low, the feed way nimble, the cost low, is easy and the flight vehicle line, is altogether easy to produce the plan polarized wave and and so on the merit.

微带天线具有体积小、重量轻、结构稳定、剖面低、馈电方式灵活、成本低、易与飞行器共行、易产生线极化波和圆极化波等优点。

The experimental results indicated that these metal oxide catalysts had better catalytic activities to the methylene chloride gas at low concentration, and the catalytic activities increased with the increase of temperature,but decreased with the increase of inlet gas concentration. The CrO3/potsherd catalytic activity was better than V2O5/potsherd, and the CrO3/potsherd catalyst displayed higher activity at the relative low temperature. When the reaction temperature was 320 ℃, the conversion rate could reach 99%, and the result of 100h catalyst stability experiment show that the catalytic activities have good stability.

实验结果表明此类金属氧化物催化剂对低浓度CH2Cl2气体有较好的催化活性，催化剂的活性随温度升高而升高，随入口废气浓度增大而降低，其中CrO3/陶瓷片催化剂的催化活性比V2O5/陶瓷片催化剂的活性好，CrO3/陶瓷片催化剂在较低温度下就表现出较高反应活性，在反应温度320℃时，转化率即达到99%，同时催化剂100h稳定性实验结果表明催化剂活性有很好稳定性，为进一步工业化应用提供理论和实践依据。
