A large releases of kinetic energy for channel CH3CS++ H of least energy might result from a dissociation mechanism according to which c-C2H4S+ isomerizes to a local minimum CH3CSH+ and then dissociates through a transition state to form CH3CS++ H. On the other hand, a predicted dissociation energy 11.05 eV for c-C2H4S ?

实验中观察到环硫乙烯离子解离成CH3CS++ H的解离通道释放出大量的平均动能，并采用G3计算预测环硫乙烯离子的解离通道，推测环硫乙烯离子异构化至次稳定态CH3CSH+结构，再经过渡态结构，断裂S-H键生成C2H3S+和H，同时释放出大量的动能。

In this paper, linear accelerometer is used to sense the rotatory joint acceleration and a model is given to describe the sensed open loop resonance, and design criteria for stable and functional control law are also proposed.

A competitor is in a legitimate position to clip a quickdraw either as long as his/her entire body has not moved beyond the karabiner at the lower end of the quickdraw in the line of the route, or as long as the competitor can clip the quickdraw without having to back climb along the line of the route.

选手应在身体之最低点高过快扣连结之最低钩环之前扣入钩环或是在无须延路线回攀的情况下扣入钩环。

A Each protection point to be used during a competition shall be equipped with a quickdraw: an approved and properly closed 8 mm or 10 mm Maillon Rapide complying with IFSC standards (EN standards or international equivalent), to which is attached a continuous, machine sewn sling complying with IFSC standards (EN standards or international equivalent) which in its other end holds the karabiner to which a competitor shall connect the rope.

每一个比赛用的确保点需挂有快扣组。符合IFSC标准（EN标准或国际相关标准）的8或10mm锁环，连接在连续扁带环符合IFSC标准（EN标准或国际相关标准），另一头连接勾环，让选手挂入确保绳。

Macrocycle with two aryl oxdiazolesThe structure of this type of macrocyclic compounds with two aryloxdiazoles attached to the nitrogen atom of amino acids is different fromthat of the above compounds.

三。含双噁二唑的大环：在这类分子中两个芳基噁二唑通过氨基酸的氮原子连接成环，而将手性中心和羧基端放于环外，这可提高分子的络合性能。

Macrocyclic supramolecular drugs forming by macrocycle s with special structure and high selectivity according to their different purpose could play important parts in the drug-controlled releasing, chiral recognition, mimic enzyme, molecular switch, and so on, especially supramolecular drugs can help to improve solubility, bioavailability of drugs and realize targeting when it encapsulates drugs.

具有独特的结构和高选择性的大环化合物所形成的大环类超分子药物可根据其目的不同在药物控制释放、手性识别、模拟酶、分子开关等方面起着重要作用，能大大改善药物的溶解度、生物利用度及实现靶向作用等，因此大环超分子药物为化学药物治疗提供了新的推动力。

The polymerization mechanisms of DTC, TMC and CL initiated by Ln 〓 were fully studied for the first time, and proved to be a"coordination insertion anionic mechanism". Monomer coordinated to rare earth metal on the carbonyl group, and opened ring via acyl-oxygen bond cleavage, forming a growing chain.

本文首次研究了Ln〓引发DTC、TMC和CL聚合的机理，证实都符合&配位插入阴离子机理&：单体首先以环外羰基和引发剂中稀土原子配位，并发生羰基加成，随之通过酰氧键断裂开环而插入到Ln-O键中实现链引发，然后各单体重复上述稀土原子参与的配位、加成、开环、插入聚合步骤，活性链在Ln-O端增长。

According to topographic information of Dongyang and Wanshou which are tentatively chosen as the sites to assemble grounding poles,the selection of d/D ratio,namely the ratio of radius of two adjacent toroids,of standard triple toroidal grounding poles,the burial depth characteristics of each sub-toroids and the feasibility of adopting such type of poles are researched.
