介绍了由磷石膏制硫酸钾的新工艺：磷石膏与碳酸氢铵在 5 - 30℃下反应，得硫酸铵溶液，该溶液与氯化钾在 30℃左右反应，并添加一种有机溶剂，得硫酸钾。

The results indicated that vegetation biomass had a significant positive relationship with vegetation coverage. They had a significant negative correlation with bulk density of soil, and a positive correlation with macroaggregate, water stability macroaggregate, organic matter content, total nitrogen content, hydrolyzable nitrogen content, available kalium content, microbial biomass, and microbial respiration. However, they had no significant relationship with total phosphorus and available phosphorus.

在其恢复过程中，植被地上生物量与植被覆盖度呈正相关，它们与土壤容重呈负相关，而与土壤大团聚体、水稳性大团聚体、有机质含量、全氮含量、水解氮含量、速效钾含量、微生物量以及土壤呼吸强度之间呈正相关，与土壤全磷、速效磷含量无显著相关性。

Abnormity sampling method was adopted and there was 128 sampling points in this field.The statistical laws of soil pH,organic matter,total phosphorus,total nitrogen,alkaline hydrolyzable nitrogen,available potassium and available phosphorus were analyzed, and the results indicated that the variation coefficient of soil nutrients was between 6.3% and 356.1%,pH was 5.3%.Using the geostatistica...

以土壤的pH、有机质、全磷、全氮、碱解氮、速效钾和速效磷含量为研究对象，研究其相应的统计规律，结果表明土壤各养分属性的变异系数在6.3%~35.61%之间，pH为5.3%；采用地统计的半方差函数分析，发现有机质，全氮，碱解氮和速效钾在一定范围内存在空间相关性；采用克立格方法进行最优内插，绘制了养分含量分布图，并对其空间变异进行了初步分析。

The NT increase the Gliadin, Globulincontent and decrease the Glutenin, Albumin contents compared with CT.1.3 In NT, 7 days after anthesis and in the sequel, flag leaf NR activityshows higher, photosynthetic ration and transpiration ratio 16 days after 5anthesis and in the sequel higher and have longer continuance ability thanthose in CT.1.4 In NT, total nitrogen contents in crop and fertilizer utilization efficiencyare lower than those in CT.2 The ecology characteristics of wheat field of NT2.1 The contents of hydrolyzable nitrogen,available phosphorus andpotassium in 0-20cm soil layer are all higher in NT fertilization zone thanthose in CT, While the differentiations are in different levels.

肥料利用率免耕各处理均显著低于常规处理。1.5 和常规耕翻处理相比，免耕处理玉米秸秆腐解率无显著差异。冬前是秸秆腐解的主要时期。小麦生育后期肥料对秸秆腐解的促进作用显著，肥料用量与秸秆腐解率存在显著相关性。2 免耕对土壤理化性状的影响2.1 在成熟期免耕施肥区，和常规耕翻处理相比，免耕处理 N3T 对0-40cm 土层碱解氮含量影响不显著。免耕处理 N3T 显著提高了 0-20cm 土层土壤速效磷和速效钾含量，对 20cm 以下土层速效磷和速效钾含量无显著影响。

The clinical test achieved 100% efficacy to kill bovine hypodermosis larvae with 10%.fenthion spot-on. The infection ratio of bovine hypodermosis declined from 30% to 0. Moreover, there was no one poisoned cattle.

用10％倍硫磷点涂剂对30头牛进行临床防治试验，表明该浓度的倍硫磷点涂剂对牛皮蝇第一、二期幼虫杀灭率为100％，可使牛皮蝇蛆的感染率由30％降至0，防治中无1例牛发生中毒。

These results provided the evidence that the formation of imino acetoxyphosphoranes intermediates was crucial to bioorganic reactions of N-phosphoamino acids.

这些结果从机理上证明N-磷酰氨基酸在水／醇体系中所发生的仿生化反应的确经历了氨基酸磷烷中间体。

Some stable imino -acetoxyphosphoranes were successfully synthesized.

建立了一套合成稳定磷烷的新方法，并成功地合成了稳定的氨基酸磷烷。

With the incessant inburst of foreign product and the continually increasing output of the high concentrated and mixed phosphate fertilizer , however, the rising speed of output supplies exceeds distinctly that of the demand.

但随着国外产品的不断涌入和国内高浓度磷复肥产能的持续扩大，其产能增长速度远远超过需求增长速度。可以预言，在未来2～3年内，我国高浓度磷复肥企业将面临残酷的市场竞争，必然导致我国磷肥产业结构的调整。

Respiratory rate and isocitric dehydrogenaseactivity in plant rootsgrown at low-P supply were markedly lower than those at P-sufficient supply.

在缺磷条件下小麦根系的呼吸强度和异柠檬酸脱氢酶活性明显低于正常供磷处理，而PEPC活性与此相反。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
