The one of N 1-N 2 bond broken ring rupture agrees with the result reported before. 其中N1-N2键断裂直接开环的机理与文献报道一致。
Methods We used optical tweezers to quantify the non-specific interaction dependence of bond rupture forces on loading rates and of bond lifetimes on applied forces by measuring the adhesions between two BSA ( Bovine serum albumin)-coated glass beads. 方法利用光镊技术,对牛血清白蛋白(Bovineserumalbumin,BSA)封闭的玻璃小球间的非特异性作用进行了系统测量,得出不同加载率下的断裂力以及不同外力作用下的寿命分布。
A Theoretical Study of Mechanisms in the Photochemical Reactions of Forming Ketene After the α-Bond Rupture in Cyclohexanone 环己酮α键断裂生成烯酮的光化学反应历程的理论研究
The results show that with increasing temperature, the rupture rate of C-N bond is faster than that of N-N bond, which verifies that the cleavage of C-N bond is dominant rupture form. 研究结果表明:随着温度的升高,C-N键的断裂速率远高于N-N键的断裂速率,表明C-N键的断裂是HMX的主要断键方式,在C-N键的断裂中伴随着N-N键的断裂。
For Nitro derivatives of methylbenzenes, the pyrolysis initial reaction is an isomerization reaction. It means the alpha C-H bond in methyl rupture, then the Hydrogen atom transfer to the Oxygen atom in nitryl to form isomer. 甲苯的硝基衍生物的热解引发反应为异构化反应&α(C-H)中的C-H键断裂,氢原子转移到邻位硝基(-NO2)中的氧原子上,生成新的异构体化合物。
The radiation decomposition of the sample is mainly the rupture of C C bond, and less is the rupture of C F bond. 材料的辐射降解主要发生在主链上,即CC键断裂,而侧基CF键的断裂相对较少。
A Theoretical Study of the Influences of Various Substituents on the Bond Rupture of Hydrogen Siting in Carbonyl α-position 不同取代基对羰基α氢断裂反应影响的理论研究
The calculated results of bond length show that the bond length of aliphatic C C is longer than that of aromatic C C, which indicates that the rupture of aliphatic C C is easier than that of aromatic C C on heating. 脂肪CC键长比芳香CC键长长,说明脂肪CC在受热过程中比芳香CC更容易断裂分解。
The results show that the fracture character of tensile samples with high bond strength is ductile rupture, and the yielded strength and rupture strength are higher than the corresponding values of samples with the conventional processing methods. 结果表明,所制备的金属拉伸试样结合强度高,表现为韧性断裂,其屈服强度与断裂强度高于相近成分下常规加工方式所加工试样的相应值。
Under traditional dressing mode, material removal mechanism of dense type grinding wheel is mainly brittle fracture of grain and bond rupture, while under the ultrasonic vibration dressing mode, the material removal mechanism is mainly ductile cutting of bond materials, abrasion and fracture of grains. 普通修整方式下密实型结合剂砂轮表面的材料去除机理主要以磨粒的脆性断裂和结合剂断裂为主,而超声振动修整方式下,材料去除机理以结合剂的延性去除以及磨粒的磨损和微破碎为主。
