For linear complementarity problems , a new smooth merit function is constructed, the linearity of LCP is well preserved as the piecewise quadratic convex property of it. By using the merit function a new Lagrangian multiplier method is proposed.

对线性互补问题，首次得到一种乘子固定时具有分片二次凸性质的光滑价值函数，它在光滑条件下完好保持了原问题的线性性质，基此提出了Lagrange乘子法。

Although the megagametophyte formed and even the double fertilization had been finished 70 days after pollination at normal temperature, the megasporogenesis had not yet been finished at low temperature.

低温(12-18℃)处理的蝴蝶兰，授粉50d开始分化胚珠原基、60 d胚囊处于大孢子母细胞时期，比常温(20-25℃)下的推迟10-15 d；授粉70 d，常温下的蝴蝶兰植株已完成雌配子体发育和双受精，而低温处理的蝴蝶兰仍未完成大孢子的发生过程。

When the pollen tube comes into the micropyle and contact one of the synergids, both synergids do not show any sign of degeneration.

在二细胞原胚的顶细胞和基细胞中，均可观察到与合子中形态相似的双亲质体和线粒体。

In this study, a stress induction expression promoter of monocotyledon (P-WCS120) was amplified from wheat genome. The result of sequencing displayed a base substitution mutant of 1 bp and an insertion mutant of 21 bps. This sequence was registered at GENEBANK as a new found sequence, because 3% of the sequence was found to be non-homologous with the original sequence.

本研究从小麦基因组扩增单子叶植物逆境诱导表达启动子P-WCS120，测序证明包括1个碱基的替代突变和21个碱基的插入突变，与原序列有3%的非同源性，被GENBANK认定为新发现序列，现已登记注册。

As the effect of noise and the plane of attractor projection must be considered, this paper introduced a useful method of reconstruction of pseudo-phase portrait based on singular value decomposition.

采用基于奇异值分解的相空间重构方法，解决了把吸引子投影到哪些基构成的平面上方能充分反映原系统特性的问题。

During the subduction and collision of Yangtze and Sino-Korean craton in Triassic period, they all subduced into mantle depth, due to the granite was relative poor in water and denser than sedimentary rocks, the kinetics rate of metamorphism of granite was much more slow than that of sedimentary and mafic volcanic rocks.
