It has been found that the lamellar morphology of irradiated polyethylene did not change with changing radiation dose.

发现室温辐照聚乙烯的片晶形态不随辐照剂量而变化。

Then the nano-sized lanthana (La2O3) was obtained by decomposition of the precursor.

以六水氯化镧与氢氧化钠为反应物，在室温下通过固相化学反应首先合成前驱物氢氧化镧，经热分解得到纳米氧化镧。

Increasing the annealing temperature from 150 to 400℃ for 1h, CeSi〓 or LaSi〓 forms gradually and the completion of reaction occurs at 300-400℃.

在超高真空下，室温，利用电子束蒸发在Si（100）衬底上分别淀积1500埃的轻稀土金属La和Ce薄膜。

The molecular weight of dextransucrase measured by SDS-PAGE was 170 kDa ,which was similar to the enzyme from Leuconostoc mesenteroides. The enzyme had an optimum temperature between 25and 30℃ and an optimum pH of 5.4. It was relatively stable in the range of pH 5.0 to 7.0, but the stability declined rapidly as soon as the temperature rose over 35℃.

以蔗糖为底物，酶促反应的最适温度为25～30℃，最适pH值为5.4，动力学常数Km值为10.43 mmol/L；酶活在pH 5.0～8.0较为稳定，在室温（25℃）保藏4 天仍有59%的酶活力，4℃保存7周酶活力仅下降一半，但在35℃以上失活很快；Ca2+对催化作用有较大的促进，Mg2+有微弱的促进作用，K+对催化反应无影响，Cu2+的抑制作用最强。

The results show that temperature does not have a significant impact on derivatization reaction; the derivatives are rapid degraded in sun light; the derivatization reaction is inhibited when the derivatization reagent is at high concentration; the reaction to produce the fluorescent derivatives is finished in 30 min, and the derivatives are stable for about 8 h at normal temperature and lightless.

研究结果表明，环境温度对衍生反应影响不显著；衍生反应对太阳光线敏感，其机理是阿维菌素衍生产物易快速发生光解；高浓度的衍生试剂对反应表现一定抑制作用；衍生反应在30min左右达到峰值，其产物在室温、避光条件下8h内保持稳定。

Any of numerous mineral, vegetable, and synthetic substances and animal and vegetable fats that are generally slippery, combustible, viscous, liquid or liquefiable at room temperatures, soluble in various organic solvents such as ether but not in water, and used in a great variety of products, especially lubricants and fuels.

油类：任一种从矿物、植物中提炼的和人工合成物质以及动植物油，一般较为湿滑，可燃、粘稠、液态的或在室温下为液体，可溶于各种有机溶剂如酸，但不溶于水，用于大量的产品，特别是润滑剂和燃料中。

We may lixiviate the Ti, Si and Al with water as separation reagent in the room temperature.

浸取试验研究表明：室温水浸即可实现渣钛分离。

There were no significant difference between the levels of C3 and C4 in sera from patients with activity lupous nephropathy and non-activity lupous nephropathy, but there were significant difference between the CH50 in sera from patients with activity lupous nephropathy and non-activity lupous nephropathy.

血清在室温下放置4h后， CH50明显降低。14例慢性肝病患者CH50及C3和C4较健康者降低，其中C3、 C4与CH50的相关系数为0.857和0.807.26例狼疮肾病患者活动期与非活动期C3、 C4含量无明显差异，而活动期较非活动期CH50明显降低，有极显著差异。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
