After mainenervations being drawn out and being dried for 4 hours at 60℃,1156 samples of tobacco leaves from different tobacco producing-area were made into powder (≤0.13 mm). Reducing sugar, total sugar, nicotine, nitrogen, potassium and chlorine of more than 1000 samples from different tobacco producing-area were determined with classical chemical or instrumental methods. By scanning these samples with Fourier transform Near Infrared spectrometer (MARIXT-I produced by Bucker) we obtained their spectrograms, pretreated the spectrograms with a chemometrics software (OPUS 5.5) to debase the noises influence on spectrum information, and built a chemometrics model by means of Partial Least2Squares. The chemometric model was optimized some times and validated with some other samples.

选取全国不同烟草生产地区的1156余烟叶样品，采用相同的预处理条件(去处主脉，60℃烘干4小时)，处理成40目待测粉末样品，采用行业经典的化学分析方法或准确可靠仪器方法测定其常规成分含量，在条件一致(20℃～24℃，环境湿度≤40 RH%)的实验室环境中，使用市场上主流的傅立叶变换红外光谱仪(德国BRUKER公司生产的MARIXT-I)上进行图谱扫描，采用OPUS5.5化学计量学软件，对光谱进行适当的预处理，减弱以至于消除各种噪声对光谱信息的影响，用偏最小二乘回归法建立常规成分预测模型，并进行了反复优化和未知样品模型外验证。

The results showed that the sludge settled properly at a influent BOD/P of 100/0.8. When the BOD/P was 100/0.6 and 100/0.3 respectively, an excessive growth of viscous Zoogloea with high moisture content was observed and non-filamentous bullring occurred. When the value of influent BOD/P was 100/0.4, more serious non-filamentous bulking occurred. Furthermore, under the condition of phosphorus deficiency the effect of microorganism on the nitrogen and phosphorus sources utilization rate were also studied in the experiments.

结果表明在进水中BOD/P为100/0.8以上的条件下，污泥的沉降性能良好；当进水中BOD/P分别为100/0.6和100/0.3时，出现高含水率的黏性菌胶团过量生长的现象，发生非丝状菌膨胀；在进水中BOD/P为100/0.4的条件下，发生更严重的非丝状菌膨胀，试验中还研究了磷缺乏条件下微生物对氮源和磷源利用率的变化。

Content of butanoic acid, methyl ester; butanoic acid, ethyl ester; hexanoic acid, methyl ester; DMHF; DMMF identified in strawberry cultivated from green house were higher than that cultivated in the open field of the correspongding nitrogen levels , and the hexanoic acid, ethyl ester could only identified in green house strawberries.

不同氮素水平温室草莓果实中丁酸甲酯、丁酸乙酯、己酸甲酯、DMHF、DMMF的相对含量和总量均比相应氮素水平的露地草莓的高，且己酸乙酯只是在温室草莓中检测到。

In farmland plant experiment,proper dosage lime application significantly increased nitrogen and protein content of Cajanus Cajan.

大田试验结果表明：红壤土上施用适量的石灰能极显著增加木豆氮素营养水平，使氮代谢平衡向着有利于蛋白质积累的方向进行。

The studies on biological characteristic revealed that the optimal temperature for the mycelial growth was 25~30℃, and the optimal pH for mycelial growth was pH 5~7. Among carbon and nitrogen sources, sucrose and calcium nitrate were best for mycelial growth. The lethal temperature for mycelial growth and spores gemination were respectively 55℃ and 60℃ for 10 min.

affinis引起草坪型高羊茅叶斑病在我国的首次报道；生物学特性的研究表明，该菌菌丝生长的最适温度为25~30℃，最适pH范围为6~7，最适碳源为蔗糖，最适氮源为Ca(NO3)2；菌丝和分生孢子的致死温度分别为55℃ 10 min和60℃ 10 min。

Methods: Forty critically patients were divided into 2 groups. In each group 20 patients were included. Twenty patients were treated with PN+EN in experimental group; 20 patients were treated with standard TPN in control group. Two groups were supplied with equal nitrogen and caloricity.

将40例危重病人按就诊顺序分为2组，每组20例，试验组接受肠外+肠内营养，对照组接受全肠外营养，2组等氮等热量供给。

Each patient in the two groups received same calory,30kcal/kg·d,and same nitrogen,0.2 g/.

两组予等热量、等氮量，总热量30 kcal/，氮量为0.2 g/。

Since 1988,23 severe acute pancreatitis recieved total parenteral nutrition with modification consisting of provision of lower calory(46 kJ/d) and higher nitrogen 0.25～0.4· kg~(-1/d,while the extremely ill patients were treated with longer TPN.

作者报道了1988年以来43例重症胰腺炎患者术后行营养支持的体会。使用低热能46 kJ·kg~(-1/d、高氮量0.25～0.4g·kg~(-1/d，术后2周内以白蛋白或血浆强化的 TPN 支持方法。将按此法治疗的23例与1988年以前的20例进行比较，结果发现，尽管 B 组的病情明显重于 A 组。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.
