质子

It was found that Lewis acid-metal is a preferable catalyst system for the polymeri- zation of aromatic nitriles, and the polymerization rate is as about 10 times fast as Lewis acid alone.

结果表明以含质子化合物或水与Lewis酸组成的体系并不是有效的催化体系，不适用于催化芳香族腈进行聚合。

At the same time, the nucleus discharges negatrons to maintain the overall balance.

它在变为质子的同时，原子核一定会放出电子，保持整体平衡。

Positive protons, neutrons and negatrons strike a balance in forming a neutral atom.

在原子内部，带正电的质子、不带电的中子和带负电的电子，三者平衡形成一个不带电的平衡体——原子。

The key part of this method is to directly spray well-mixed suspension of metal oxides instead of pre-synthesized ceramic powders on the anode substrate in order to make the membrane dense and form the pure ceramic phase at the same time.

通过直接将金属氧化物混合然后沉积到阳极基底表面，利用金属氧化物在高温烧结时发生反应，使质子陶瓷膜电解质层的成相与致密在一步烧结过程中完成。

Fermilab has added the two-mile Main Injector accelerator to increase the number of proton-antiproton collisions in the Tevatron, greatly enhancing the chances for important discoveries in Run II.

费米实验室增加了两英里长的主要喷油加速器增加质子反质子碰撞的Tevatron ，大大增强了机会，重要的发现在运行二。

Employing high-dilute method and 5-fold excess amine prepared two new "two-armed" acyclic diamine intermediates I_a and I_b, which are also intermediates of synthesizing microcyclic compounds, and eight aromatic Schiff bases, II_, were synthesized from reaction of I_a or I_b condensing with different aromatic aldehydes. Their composition and structure were characterized by Elemental analysis, IR, UV-Vis, LIF,~1HNMR and MS. The hydrogen bond interactions and MS fragmental patterns were also discussed.3. Several novel transition metal complexes using II_a as ligand were synthesized and identified by Elemental analysis, IR, UV-Vis,~1HNMR and molar conductivity.

1，采用高度稀释及胺过量五倍的方法合成了两个具有吡啶双酰胺臂的非环二胺Ⅰ_a和Ⅰ_b，并以它们为中间体进一步合成了八个芳香席夫碱Ⅱ_a-Ⅱ_h，通过元素分析及各种波谱测试鉴定了它们的组成与结构，对化合物的UV-Vis、LIF、IR、~1HNMR及MS进行了较为详细的讨论，还探讨了席夫碱的氢键相互作用及质谱裂解方式； 2，以席夫碱Ⅱ_a为配体合成了几个新型的过渡金属配合物，并通过元素分析、UV-Vis、IR、~1HNMR、摩尔电导及DTA—TG对其进行了表征，讨论了化合物的配位情况及配体在配位中的脱质子行为。

From the top of the tower Galileo dropped a light ball and a heavy ball at exactly the same time.

质子电荷飞域的边界并不象弹子球的表面那样分明。

If hit with a precise proton torpedo volley, the entire station could be destroyed.

如果用一次精确的质子鱼雷齐发命中之，就可以炸毁整个太空站。

If hit with a precise proton torpedo volley, the entire station could be destroyed.

如果对其使用一次精准的质子鱼雷连射攻击，就可以摧毁整个空间站。

If hit with a precise proton torpedo volley, the entire station could be destroyed.

只要有一枚质子鱼雷准确地击中它，整个基地都会爆炸。

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.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
