The content of 1,8-cineole in eucalyptus oil was determined using cyclohexanone or acetophenone as internal standard.

通过用环己酮和苯乙酮作内标物，对含量 80 %桉叶油中 1，8-桉叶油素含量的测定进行比较，结果表明，用苯乙酮作内标测定，标准偏差为 0 。2 7，变异系数为 0 。33%，而且毒性较小，是较理想的内标物。

So we researched the relationship between the acraldehyde contamination and cooking activity. We choose four time, 9:00 and 15:00 the cooking activity is very few, so the contamination is low, but 11:30 and 17:30 the contamination is very high, this concentration is 2.6 times an much as the front one.

检测结果表明丙烯醛的浓度和烹饪活动的多少有密切的关系。9：00和15：00食堂内烹饪活动比较少，丙烯醛的浓度明显降低，而11：30和17：30是两个就餐高峰，在这两个时间段内餐厅内的丙烯醛浓度明显升高。

During the process of long-time adaptive evolution, wetland plants adopted a series of special strategies to acclimate to salt stress. The main strategies are: 1 life history adjustment, e. g., to adjust seed germination time, implement seed dormancy and viviparity, and change reproductive manner to escape from direct salt stress, 2 morphological adjustment, e. g., to adjust biomass allocation pattern, age stem, defoliate, and carnify vegetative organs to isolate the redundant Na(superscript +) to the inactive-metabolism shoots or exclude the Na(superscript +)from tissues; 3 anatomic adjustment, e. g., to sink stoma, develop aerenchyma, and thicken cuticle and phellogen to maintain normal photosynthesis and respiration; 4 physiological and biochemical adjustment, e. g., to exclude and excrete salt, compartmentalize ions, adjust osmosis, do selective absorption, regulate hormones, and induce antioxidative enzymes to maintain the osmotic equilibrium and eliminate the active oxygen in cell; and 5 molecular level adjustment, e. g., to start up many salt-induced genes to regulate the metabolic responses to salt stress.

在长期的适应进化过程中，湿地植物形成了多种适应盐胁迫的策略，主要有：1生活史方面，植物可通过种子萌发时间的调整、种子体眠、胎生、繁殖方式的改变等逃避盐度的直接伤害；2形态学方面，植物可通过生物量分配模式的调整、茎的老化、落叶及营养器官的肉质化等将多余的Na隔离到代谢不活跃的茎中或将其排出体外；3解剖学方面，植物可通过气孔下陷、发达的通气组织、增加细胞木栓层、角质层及栅栏组织的厚度等以维持植物正常的光合作用和呼吸作用；4生理生化方面，植物可通过离子区隔化、拒盐、泌盐、选择性吸收、渗透调节、激素调节及抗氧化物酶的诱导等来维持细胞内正常的渗透压，清除胞内活性氧分子；5分子水平方面，植物可通过多种与盐胁迫相关的基因来调控细胞内的多种代谢反应。

Disperses inthe process, the fire critical dangerous condition usually determinedaccording to the below situation:(1) Above 2m in the spatial hazeaverage temperature is not bigger than 180 ℃;(2) Below 2m in thespatial haze temperature does not surpass 100 ℃;(3) Below 2m in thespatial smoke aerosphere the CO density does not surpass 0.25%.

疏散过程中，火灾临界危险条件通常按以下情况确定：①2m以上空间内的烟气平均温度不大于180℃；②2m以下空间内的烟气温度不超过100℃；③2m以下空间内的烟气层中CO的浓度不超过0.25％。

As the pressure inside the spacesuit than normally low, there may human tissue inside the release of nitrogen in the formation of air embolism within blood vessels, leading to decompression sickness, and even endanger human life.

由于航天服内的压力比正常情况下低，有可能会使人体组织内的氮气释放，在血管内形成气栓，导致减压病，甚至危及人的生命。

After lighting the firearms set off,the solid nitrogen grain is quick to gasify,the nitrogen of large quantity nitrogen spirit blows to rise the air sac immediately,and in the mighty impact dint under,the air sac hurtles to open the cover on the steer device but the safety launche.

在正驾驶位的气囊装在方向盘的中间位置，副驾驶位的安全气囊安装在正前方的平台内部，在意外发生的瞬间可以有效的保护驾驶员和副驾驶位乘员的头部和胸部，因为正面发生的猛烈碰撞会导致车辆前方大幅度的变形，而车内乘员会随着这股猛烈的惯性向前俯冲，造成跟车内构件的相互撞击，另外车内正驾驶位置的安全气囊可以有效的防止在发生碰撞时方向盘顶到驾驶者的胸部，避免致命的伤害。

Entrapped air in the hot water heating system piping is dispersed by the internal agitator of the air scoop as the water is recirculated within the heating system piping.

当供暖系统内的水在循环流动时，导气罩内的内置搅拌器将供暖系统热水中的气体截留并分离出来。

In order to solvepiecewise algebraic varieties, we propose a new method to compute an algebraic varietyon a convex polyhedron by adding hyperplanes with the method of Groebner bases. Thus,the algebraic variety on the convex polyhedron is transformed to the positive solutionsof a system of polynomials. Besides, the minimal decomposition is also obtained.

通过添加超平面技巧将Groebner基方法应用到凸多面体内任意维代数簇的计算上，从而把凸多面体内的代数簇转化为另外一组多项式方程组的正解，并且得到了该代数簇在凸多面体内的极小分解。

In the shallow soil with the depth of 0~50 cm below the ground surface,the extent from 0 to 50 centimeters, the change of the δ13C of the soil carbonate is positively related with the depth in the upper soil profile from 0~30 cm,but it will increase rapidly in the lower soil profile as the result of the existence of salined and alkali soil layer.

盐碱化土地在0～50 cm的深度范围内，土壤碳酸盐的δ13C值变化规律为：0～30 cm深度内，土壤碳酸盐的δ13C值随深度的增加而逐渐减小；在30～50 cm范围内，如果有盐积层或碱积层的存在，则土壤碳酸盐的δ13C值迅速增加。

Results All 19 patients came from a large family had serous nausea,vomiting,abdominalgia and diarrhea in one hour after eating Amanita phalloides cooked thoroughly.

结果 全部患者均于 1h内出现严重的恶心、呕吐、腹痛、腹泻等胃肠道症状，一老妇和一男童于中毒后 6h内死亡，其余患者胃肠道症状均于 2 4h内缓解。
