Firstly, the acute cytotoxicity of profenofos on FG-9307 cells was studied, it was found that the cell growth rate was markedly reduced by profenofos at all the concentrations tested; and that the fine structures of the cells were also altered by profenofos, as evidenced by dilation of nuclear membranes and mitochondria cristae, and presence of enlarged lysosomes with engulfed organelles and numerous vacuoles in the cytoplasm.

丙溴磷对FG-9307的急性细胞毒性研究结果发现：1）在所有实验浓度下，细胞的生长速度均受到抑制。2）细胞的超微结构被丙溴磷所改变，最明显的特征则是线粒体损伤严重，嵴肿胀，部分溶解破裂；核膜肿胀，有溶解；细胞内的电子密度高的溶酶体增多；内质网的膜溶解，核糖体从粗面内质网上脱落下来，游离于胞质中。

Cold smelting charge ratio was respectively 20%,25%,28%, by optimizing slag making and oxygen blowing process of dephosphorizing pretreatment period and decarburizing period,oxygen consumption rate increased from 20～30% to 40～50% than conventional process in dephosphorizing pretreatment period and slag charge was controlled at 8～15kg.t-1 in decarburizing pretreatment period.

在冷料比为20%、25%、28%条件下，通过优化脱磷、脱碳期供氧和造渣工艺，脱磷期耗氧比从传统工艺的20%～30%提高到30%～50%，脱碳期渣料加入量控制在8～15 kg.t-1.50炉工业试验结果表明，脱碳期一倒温度达到常规冶炼控制水平，一倒、控制水平明显好于常规冶炼工艺。

The results were as follows: Compared with natural growth, defoliating and shielding photosynthesis organs decreased the contents of starch, fat and iron in wheat grains and yields of starch, fat, protein, ash, phosphorus, potassium, zinc, iron and calcium in a single ear.

结果表明，剪叶遮光后小麦籽粒中淀粉、脂肪、铁含量比正常生长降低，灰分、磷、钾、锌、钙含量提高，而对蛋白质含量影响很小；剪叶遮光后小麦籽粒淀粉、脂肪、蛋白质、灰分、磷、钾、锌、铁、钙单穗产量均比正常生长降低。

The mechanisms, main influencing factors and new available approaches of denitrifying dephosphatation were elaborated.

综述了反硝化除磷技术的原理、主要影响因素和实现反硝化除磷的新途径。

To achieve complete denitrifying dephosphatation, the co-existence of exterior carbon source and nitrate should be avoided for the best.

要想获得理想的反硝化除磷效果，应尽可能使外碳源和硝酸盐不在同一时间内共存，否则需调整二者的比例才能获得氮、磷的完全去除。

The results indicates, with the same level of other parameters, the TN removal can reach 80.0% and 70.9% with the control of dissolved oxygen under the levels of 0.3-0.6mg/l and 0.6-0.9mg/l, respectively; the TN removal upgrades from 80%, 83% to 84.1% with the decrease of sludge load in the system from 0.1, 0.07, to 0.05gCOD/gMLSS·d; the nitrogen removal only reaches 58% when C/N is 4, but can reach more than 80% when C/N is at or over 7, which indicates that the TN removal increases when higher C/N ratio; when HRT increases from 12h, 18h to 24h, the TN removal also increases from 78.6%, 82.0% to 83.0%; the TN removal average in the system increases from 75.6%, 78.5% to 83.0% with the increase of sludge age from 18d, 20d to 24d; the low oxygen conditions in the modified Orbal oxidation ditch model do not decrease the effect of COD removal, and the dissolved oxygen gradient with the distribution of 0-2-1mg/l in the system ensures the COD removal reaching the range of 80%-86%; and the phosphate removal, however, is not good enough, which varies from 40% to 50%, even lower than 35% in occasional situations, and the phosphate concentration in the outflow varies in the range of 1.28-2.38mg/l, which dissatisfies the discharge standard with the level of 1.0mg/l.

试验结果表明，在其它参数相同的情况下，将外沟道的溶解氧分别控制在0.3～0.6mg/l 和0.6～0.9mg/l 两个水平，外沟道中TN 去除率分别为80.0%和70.9%；系统中污泥负荷分别为0.1gCOD/gMLSS·d、0.07 gCOD/gMLSS·d、0.05 gCOD/gMLSS·d时，随着污泥负荷的降低，TN 的去除率却是上升的，分别为80%、83%、84.1%；本试验中，当C/N 为4时，仅能获得58%的脱氮率，当C/N 为7 或更高时脱氮率能达到80%以上，进水C/N 比值越高，总氮的去除率越高；在本试验中采取的水力停留分别为12h、18h、24h 时，外沟道中的总氮去除率随水力停留时间的增加而增加，分别为78.6%、82.0%和83.0%；当系统泥龄分别为18d、20d、24d 时，系统平均TN 去除率分别为75.6%、78.5%、83.0%，随着泥龄的增大TN 的去除率增加；改良型奥贝尔模型的低氧条件并没有降低COD 的去除效果，系统0-2-1mg/l的溶解氧梯度分布使得COD 去除率一般都在80%～86%之间；本试验中磷的去除效果不好，去除率基本在40%～50%之间，有的甚至低于35%，出水磷的浓度在1.28～2.38mg/l 之间，低于1.0mg/l 的出水排放标准。

The results suggest: the optimum pH is 6.0~7.0 and phosphorus content can not exceed 200μg/ml in culture medium when assessefeed available phosphorus with method of everted intestinal sacs.

Roger and co-authors （1993） suggest that in some instances inoculation may be useful, particularly since the inocula produced with high levels of P may have an advantage over P-limited indigenous strains; however, they suggest management practices that enhance the proliferation of native cyanobacteria to increase the N-fixing potential of these organisms.

Roger 和他的合作者们（1993）认为在某些时候接种剂是有用的，特别是高磷条件下培养的菌种对于低磷土著品系来说有一定的优势；但他们建议采用增强固有兰细菌生长繁殖的管理措施以提高这些微生物的固氮能力。

But available P is respect of vulnerable to the effects by artificial fertilization, It reflecting the fertilization level, and can find out the available P content of the farm No 16 is higher than that of other two places through the data, which can indicate the manuring amount of the farm is larger than other two place. these three areas are all cotton growing areas, this is the reason why the cotton yield of the farm is higher than other county.

而速效磷则因为容易受人为因素的影响，能够表现出施肥量，通过数据可以看出十六团的速效磷含量比其他两个地方高出很多，可以表明兵团的施肥量要比地方的大，这三个地区都是产棉区，这也是兵团的棉花产量高于地方棉花产量的原因之一。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
