More than 50% grain dry matter of all genotypes came from remobilization of accumulated assimilation products before the anthesis stage, except YY22 and SZ1 under no N application; meanwhile, it is true for all genotypes under the N application.

不施氮处理下，除豫玉22号和陕资1号外，其它品种子粒干物质中50％以上来自于开花前期储存同化物的再转移；施氮后则所有品种的子粒干物质中50％以上均来自于开花前期储存同化物的再转移。

The changes of nitrogen content, free amino acid, C/N ratio and chlorophyll content of wheat in wheat-faba bean intercropping system were studied by pot experiment with 3 N levels 0, 75 and 150 mg Nkg^(-1 soil. The results showed that leaf nitrogen content of intercropped wheat was higher than that of monocultured wheat at 3N level at tilling and booting stages, but was lower at heading stages.

首次提出并运用&取代基模型&(即将金属原子视为四唑环上的取代基、对金属配合物的处理采取与计算衍生物完全相同的模式)较为简便地计算研究了系列四唑金属配合物的热解反应，发现开环形成叠氮化物的活化能与它们的实验撞击感度之间存在良好的线性关系。

Autoinducer_Ph-1 exploits a traditional rice cultivation technique from SE Asia where Azolla is grown in large quantities and used as an organic, nitrogen rich fertilizer in the rice paddies. A naturally occuring symbiosis between the water fern Azolla and the cyanobacteria Anabaena is reworked to force a real and a synthetic culture of bacterial cells to exhibit symbiotic behaviours.
