XPS analyses were carried out for BXO films containing different oxygen contents systematically. Chemical state of boron were investigated in detail and the formation mechanism of "Boron suboxide" phase was achieved.

系统地改变薄膜氧硼比，探讨了离子束辅助沉积BXO薄膜各不同硼氧比的结合能变化，给出"suboxide"相形成的可能机制。

The results indicate that the BC3 compound starts to oxidize at about 620℃, compared to about 510℃ for pure C, which reveals the inhibiting effect of substitutional boron.

这种层状硼碳化合物在620℃左右开始氧化，比纯碳样品的初始氧化温度高大约100℃，替代的硼明显的改善了破的抗氧化性能。

The resistivity of the polysilicon films could be controlled under different dopant concentration and different anneal temperature. The changes of resistance with the temperature were measured. The temperature coefficient of resistance value was about 1‰ when the boron concentration was 5X 10 /cm and the anneal temperature was 900℃.

2制作了不同掺硼浓度和退火温度的多晶硅电阻，测试了阻值随温度的变化，在掺硼浓度和退火温度分别为5×10~(14)/cm~2和900℃时得到了接近1‰的TCR值。

However, the conditions of solid state phase transformation of BN nanoparticies are still rather harsh.

尽管如此，以六方氮化硼纳米粉为原料制备立方氮化硼时，仍需要使用很高的温度和压力。

A space or line of the staff.lined with boron or filled with boron trifluoride gas.

有具线纹的硼或充满三氟化硼气体的小室。

Treat each flask as follows. Add 5.0 mL of a solution prepared by dissolving 14 g of boron trifluoride in methanol to make 100 mL, swirl to mix, and reflux for 15 minutes or until the solid is dissolved.

在每一个锥形瓶中，加5.0mL三氟化硼溶液（取14g三氟化硼，用甲醇溶解并稀释至100ml），搅拌使混合，回流15分钟或直至固体物溶解。

Using the procedure described in Example 1, boron trifluoride diethyl etherate (1.49 liters, 12.1 moles) was added followed by 1.21 liters (12.1 moles) of borane-dimethyl sulfide at reflux.

用所述的程序例子1 ，硼乙醚（ 1.49升， 12.1痣），然后又说是1.21升（ 12.1痣）的硼-二甲基硫醚在回流。

In the field of visible photosensitive resin, the absorption spectrum, excited state, solvent polarity effect, fluorescence spectrum, fluorescence quenching, concentration effect, photo fading, reaction mechanism as well as photopolymerization kinetics of xanthene iodonium salts and cyanine dye-borate were discussed. It is found that under the radiation of visible light, intra-ion-pair electron transfer reactions occur in bis salt of fluorescein and unsymmetrical trimethine cyanines containing quinoline end group triphenyl-butylboron, and the fading rate is very high.

在可见光敏树脂部分，通过对呫吨染料碘鎓盐和菁染料-硼盐体系的吸收光谱性质、激发态性质、溶剂极性效应、荧光光谱、荧光猝灭、浓度效应、光褪色反应、光聚合动力学等的研究，结果发现：荧光黄双二苯基碘鎓盐体系和含喹啉环端基不对称三甲川菁染料-三苯基丁基硼盐体系在可见光作用下均发生离子对内电子转移反应，且光褪色反应速率很高。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
