All these QTLs affected the hybrid fertility in the same direction.For eachlocus,the genotype consisting of the'02428'and Balilla alleles exhibited higher fertilitythat the one of Nanjing 11 and Balilla alleles.

所有位点对杂种育性改变的方向是一致的，即广亲和品种'02428'的等位基因可使杂种育性提高，而籼稻品种'南京11'的等位基因则使杂种育性降低。

Electron-withdrawing groups decrease the reactivity of benzylic C - H whileelectron-releasing groups enhance its reactivity. This is consistent with the well-knownelectron-demanding character of the Rh-carbene complex.

从相对速率的数值〓可以看到，吸电子基使苯甲位反应活性降低，给电子基使苯甲位反应活性增大，这和Rh-卡宾的亲电性一致。

The invention relates to a processing method of preventing frostbite and restarting of hydrogen electric pile, whose characteristic lies in the treating processes includes: When the electric pile turns off, the unsaturated fuel gas or the nitrogen, through the circle boast to clean the dissociate water; drying the MEA film module to keep the water content below the stipulated temperature which does not ice up; then the recycle gas through a wet exchanger to dry and the dried gas is continue used in the dry pile step; when restarting the electric pile, the recycle gas must heats then through the pile to elevate the temperature, then heats the fuel gas and the oxidant of the gas source, through the weting of the wet exchanger enters to the calefactive pile, enhances the wet step of the film module in the pile, starts the power output of the pile.

本发明涉及一种氢电堆的防冻和重新启动时的处理方法，其特征在于处理过程包括：电堆停机时，将水蒸气不饱和的燃料气体或氮气，通过循环吹扫除去电堆的游离水；干燥其中的MEA膜组件，使膜组件含水量降低到规定低温下不结冰的程度；而后再令循环气体通过一个湿交换机将循环气体干燥，以及被干燥后的循环气体继续用来干燥电堆的步骤；在电堆重新启动时，须将循环气体加热后通过电堆，使电堆升温，然后再将气源的燃料气及氧化剂加热，通过湿交换机加湿后进入已升温的电堆，提高电堆中膜组件的湿度的步骤，开始电堆的功率输出。

AT-deficient plasma had significantly smaller R values compared with control, and dilution did not change R values in AT-deficient plasma. Celite activation eliminated dilution-associated changes in R values in control plasma but resulted in linear decreases R(2 = 0.88-0.96, P 0.0001 in alpha, A, and G in response to dilution.

结果显示对照组稀释后R、A、G值均明显下降，a值没有改变，而AT缺乏组与相应对照组相比R值明显降低，但稀释对其R并没有影响，硅藻土激活后使对照组中稀释造成R值下降的效果被消除，但使a、A、G值随稀释程度呈线性下降。

Therefore,a centerless clustering algorithm considering cluster structure's stability is proposed,and cluster maintenance scheme is proposed too.

为了降低路由维护开销，使无中心分群结构很好地适用于大规模自组网，最首要的任务是使分群结构尽量稳定。

应用本文的原理，采用优化综合的方法，可以使圆柱蜗杆传动直接实现点接触和完全互换，并具有良好的接触特性，使对误差的敏感性降低，缩短装配中的辅助时间，且传动质量得到改善。

The results indicated that the organically modifying precursors could densify the gel glass, but the thermal stability was reduced simultaneously.

结果表明，有机改性先驱体能使凝胶玻璃结构致密，但同时热稳定性降低；对于荧光性能，MTMS和VTES可使其有一定的提高，但它们的最大含量不能超过50%，否则凝胶易失透，而GPTMS能大幅提高凝胶的荧光性能。

The reason may be that complex formed by rhodium and halide was difficult to produce the catalytic active species. Therefore halide ion was the poison for the rhodium catalyst in hydroformylation of olefins in ionic liquid. The effect of double long chain cationic surfactant (DCMAB, dicetyl dimethylammonium bromide) on selective hydrogenation of cinnmaldehyde catalyzed with RuCl3·x H2O/TPPTS was studied.

进一步的研究表明在使用有良好反应活性的两种催化剂HRh3 、Rh_2进行催化反应时，向体系中加入含有卤离子的化合物时将使反应活性大大降低，而且随着卤化物加入量的增加，催化剂的活性迅速下降，这是卤离子可能和金属铑作用使它难于生成催化活性物种，进一步证明卤素离子是引起催化剂活性下降的极其重要的因素。

Like sample of jute fiber reinforced composite, the tensile strength, flexural strength, module and temperature resistance of ramie fiber reinforced polypropylene are improved but its toughness and ductibility decrease.

与黄麻纤维类似，芒麻纤维的加入使聚丙烯的强度、模量和热变形温度提高，但使其韧性和延性降低。
