Viability of spores in crystals. An interesting sidelight of these experiments is the fact that the occluded spores showed no loss of viability or drop in count after 3 years of storage at room temperature.

晶体中孢子的生存能力：这些实验的一个有趣侧面是，封闭孢子在室温贮藏3年后均未失去生存能力或计数下降。

The study shows that, under the conditions of the concentration of sodium silicic acid being 4%-8%,the pH＜4, and the reaction time being about 5 hour, the stable polysilicic acid is made.

以水玻璃、废盐酸为原料，制备聚硅酸，研究表明：在硅酸钠浓度为4%～8%，pH小于4的条件下，室温熟化5h左右，可制得稳定的聚硅酸。

It has been found that there are some texture flaws such as large grain、badly distorted twin and streaky structure. But recrystallization grains ofaround 19μm in diameter on average are obtainable through heat treatment at300℃for 30min by air-cooling, meanwhile the twin and streaky structurethat would weaken the plasticity of alloy are eliminated; significant elementsare holding temperature、holding time、cool-down methods. Mechanicalproperties of tube are obtained, simple tension elongation ratio of arc testsample increases from 10.8% to 20.1%, elongation ratio with elastic internaldie of tube increases from 8.0% to 14.9%.

研究结果表明：挤压成型的AZ31镁合金管材组织中存在变形程度很大的孪晶、大尺寸晶粒、丧失了进一步变形能力的条带状组织等易导致后续塑性加工时变形不均，引起断裂的组织缺陷；采用最佳等温热处理工艺以20℃／min加热至300℃保温30min后空冷处理可以使试样平均晶粒直径从挤压态的50μm细化为19μm，同时基本消除上述组织缺陷；明显影响热处理效果的因素为保温温度、保温时间、冷却方式；室温下，采用最佳工艺热处理前后管材弧形试样的单向拉伸伸长率由10.8％提高至20.1％，管件的自由胀形极限伸长率由8.0％提高至14.9％。

It has not yet been reported that a material simutaneously possesses such high σ〓 and K〓 elsewhere.

目前还未见其他复合材料同时具有这样高的高温弯曲和室温断裂韧性的报到。

E. Contact with 5% soda ash solution at room temperature for 24 hours may show no effect.

e。室温下，在5％的苏打水中放置24小时无反应。

In situ high-pressure energy dispersive X-ray diffraction experiments on framework silicate sodalite were carried out by using the diamond anvil cell device with a synchrotron radiation source at Beijing Synchrotron Radiation Facility.

在室温下使用金刚石对顶砧高压装置和同步辐射光源，对架状硅酸盐矿物方钠石进行了原位高压X射线衍射实验，最高压力达到17.4GPa。

PEG400, which is poisonless, low cost with good capability of carrying sodium ion, was used as catalyst, and sodium cyanide owing to its less toxicity, stability, less amount in the reaction, was used as cyanating reagent in the reactions.

在有机卤代化合物或酯与PEG400、NaCN的用量比分别为1∶0.03和1∶1.3的条件下，获得了高收率（84％-96％）和高纯度（≥98％）的腈化物。通过几种不同溶剂下反应的对比，选择了以苯为溶剂，在酰氯与PEG400、 NaCN的用量比分别为1∶0.05和1∶1.2及反应温度为室温的条件下，合成了酰基腈化物。

PP–Ag NPs were obtained in water by reacting silver nitrate with sodium borohydride in the presence of 4-(prop-2-ynyloxy)pyridine solution at room temperature for 2 h.

PP－Ag NPs是在存在4（丙炔-2-基氧基苯基）吡啶溶液的情况下，通过硝酸银与硼氢化钠在室温下反应2h而在水中得到的。

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。
