DPU at a concentration of as low as 10^(-7)mol/L retained the chlorophyll of Spirodela half-fronds under long-day conditions. From 10^(-5)~2×10^(-4)mol/L it prompted the synthesis of chlorophlly and the serine: glyoxylate aminotransferase activity, increased dry weight, and retarded the senescence of half-fronds.

在长日照条件下，10^(-7)mol/L的二苯脲对紫萍半叶状体就有保绿的作用，10^(-5)~2×10^(-4)mol/L的二苯脲还可以明显地促进叶绿素的合成和干重的增加，提高丝氨酸：乙醛酸转氨酶的活性，延缓半叶状体的衰老。

Efficient usage of the main storage material in megagametophyte before it falls off from seedling is important for seed germination of Pinus edulis Engelm.. We examined and compared lipid usage in both megagametophyte and cotyledon with electromicroscopic technique, the length, dry weight, starch content and FBPase activities of each part of the seedling were measured and compared.

采用电镜技术观察了黑暗中萌发中食松子叶和提供营养的雌配子体中脂肪体和与脂肪利用有关的乙醛酸循环体的变化，测量比较了子叶、下胚轴、根的长度、干重、淀粉含量，以及果糖1，6二磷酸酶的活性变化，对贮藏物质脂类、淀粉的利用及与生长的关系进行了分析。

Simple examples of aldehydes are methanal and ethanal (acetaldehyde, CH3CHO).

简单的醛有甲醛和乙醛（ CH3CHO ）。

So a person with an high tolerance to Nembutal would already have a high tolerance to CH.

因此，对"戊巴比妥"有耐药性的人早就对"水合三氯乙醛"有了很高的耐药性。

Plus Chloral Hydrate has a cross tolerance with Nembutal.

此外，"水合三氯乙醛"和"戊巴比妥"还有交叉的耐药性。

Osb. were stored in ultra low oxygen condition (0.3% O 2 + 0.0 %CO 2) at 5 ℃ and in normal air condition at 5 ℃ and 10 ℃ to investigate the contents of volatile compounds in fruit tissue, in order to evaluate the fruit quality and physiological disorder in ultra low oxygen atmosphere storage.

Osb 。果实在短期超低氧贮藏条件下，果皮和果汁中乙醇和乙醛等挥发性物质的含量，以及它们在不同贮藏温度和货架存放期间的变化和对果实风味品质的影响。

The present artical provides a process for the production of pure acetaldehyde oxime by the principle of aceotropic extraction and the selected solvent.

介绍了通过所选用的溶剂，利用共沸萃取原理，制取纯乙醛肟的工艺过程。

The method of preparing acetaldehyde oxime is developed with hydroxycamine sulfate from sodium nitrite and sulfur dioxide,and the optimal condition is also given.

研究了以亚硝酸钠和二氧化硫为原料，经硫酸羟胺合成乙醛肟的方法。

According to state corrosion rate experiment,it is possible that acetaldehyde oxime is reducer in the oxidation solution,and its result is very good in the boiler acid cleaning of some power plant.

根据静态腐蚀速率试验，证明乙醛肟在氧化性溶液中用作还原剂是可行的。

The synthesis of glyoxylic acid by ozonization of maleate was studied, the influence of technological parameter on the reaction during ozonization process were investigated.

对马来酸酯臭氧化合成乙醛酸的技术进行了研究，重点考察了臭氧化过程中的工艺参数对反应的影响。
