室温下储存在密封的容器里一个星期。

The bread will keep at room temperature for three days, and may be frozen, airtight, for up to two months.

面包在室温下能保持3天不变质,在被冷冻或密闭保存的情况下能保持长达两个月的时间。

When 5 mol% of 1a was used to catalyze the reaction at 0℃to room temperature, the aldol products were obtained with up to 96% ee, which were comparable to the effect with 30 mol% of L-proline as catalyst.

在0℃~室温下,以5mol%的1a催化即可获得相当或优于30mol%脯氨酸本身所具有的催化效果,ee值最高可达96%。

Through experiment, we have found that the combination of naphthol/sodium naphtholate is a high efficient bifunctional catalyst for direct aldol reaction.

通过实验,我们发现并筛选出了一组活性较高的β-萘酚和其钠盐双功能催化剂,该方法不需要预先活化Aldol反应的底物就能直接反应,且反应可在室温进行,条件温和,速度快,收率高达98%。

Then, an aliquot of the resulting aqueous extract was subjected to SPME with 60μm PDMS/DVB fiber for 40 min at room temperature, with the solution being stirred at 1100r/min.

土壤样品以水为萃取剂,在微波加热100℃下萃取5min,然后在室温和搅拌速度为1100r/min条件下用60μmPDMS/DVB纤维萃取40min,之后进行HPLC分析。

Seven 1-iodoalkynes in yields of 78%~91% were synthesized by reaction of terminal alkyne s and cesium hydroxide in dry THF at room temperature for 3 h followed by treatment with iodine.

The results reveal that the double peaks exist in the age-hardening curves of both the unreinforced and the reinforced MB15 allo...

结果表明,MB15及其复合材料的时效硬化曲线上均存在双峰现象;SiCw的加入既提高了MB15的硬度,又加快了其时效速度;混粉方式对晶须分布及SiCw/MB15复合材料的室温力学性能影响很大。

The stability of aloin decreased with the increase of temperature and heating time. However, the absorbency of aloin did not change with time under room temperature (20℃). The aloin was sensitive to light, and the aloe juice showed a yellowish green sediment in 2 hours after exposed to sunlight. The stability of aloin declined when the pH value arose. The aloe juice was more stable under lower concentration of sodium chloride and sucrose.

结果表明:加热的温度越高,时间越长,芦荟苷的热稳定性越差,而在室温下(20℃)芦荟苷的吸光度基本不随时间改变;芦荟苷具有光敏性,在太阳光照射下,2小时后便出现黄绿色沉淀物;芦荟溶液随着pH的升高,其稳定性下降;低浓度的氯化钠和蔗糖对芦荟汁液稳定性的维持比高浓度的效果明显。

XRD shows: when the value of x is between 0.1 and 0.3, the alloying thin film remains the structure of hexagonal wurtzite and the angle of (002) diffraction peak becomes bigger as the value of X increases; The photoluminescence spectra at room temperature shows that the PL spectra of the alloying thin film is composed of the stronger UV emission band and weaker visible band, and UV emission peak will have the blue shift with the content of Mg increasing and the visible emission weakened.

XRD衍射测试表明:在0.1<x<0.3范围内,合金薄膜仍然保持氧化锌六角型纤锌矿结构,(002)衍射峰位随x的增大向大角度方向移动,在X≥0.3的范围内,合金薄膜的结构则为氧化锌和氧化镁的混合结构;室温光致发光谱表明:ZnMgO合金薄膜PL谱都是由较强的紫外发射带组成,且随着Mg含量的增加紫外发射峰位发生蓝移,同时可见发射增强。
