The research shows that asymmetry information can cause sluggish behaviour for the same type of employees, the exogenous layoff probability can restrain labour positivity and threaten the efficient labour of the employees, and reduce the agent cost. While endogenetic layoff probability cannot impact on the function of the assembled mechanisms consisting of promotion and fixed income under asymmetry information, which can avoid the moral risk of employees to achieve the same degree of their labour under symmetry information.

研究表明：非对称信息会诱导同类员工偷懒行为，外生裁员概率抑制员工的劳动积极性，对员工的有效劳动构成一种威胁，但裁员概率降低了代理成本；外生裁员机制并不影响信息非对称下的晋升激励和固定收入组合机制持有的避免员工道德风险的功能，实现员工对称信息下的努力程度；以绩效评估为特征的内生裁员机制能够促使异类员工更加努力工作，提高产量，相应地也增加了工资支出；高能员工比低能员工更努力，提高员工裁员绩效标准和高能员工比例，有利于降低代理成本。

Deterministic search process restricts its flexibility, determined on the basis of fixed TS, according to the information of moving, add a probability function to the evaluation function, increase the probability factors , broad the search area, makes a better solution a better chance of being selected.

T S中确定性的搜索过程制约了它的灵活性，所以在禁忌搜索原则确定的基础上，根据搜索中的移动信息，增加概率性因素，在评价函数中增加一个概率函数，把确定性选择过程变为概率性的，从而改进搜索方向，拓宽搜索领域，使得更好的解有更大的被选中的机会。

One of the key techniques in Continuous Handwritten Character Recognition is how to model every word entry in lexicon and every sentence that made up by the words. Due to the HMM′s characteristic of time sequence modeling capability, a Cascaded Hidden Markov Models, which defines model connection probability and state transition probability between HMMs, is proposed in this study.

The ideal vehicle convoy is built after the uniformly distributed load is used as the equipollent load. With the maximum function of influence line area under the vehicle convoy, the probability of specific vehicle convoy passing influence line alone and the total weight distribution of specific vehicle convoy, the maximum probability distribution of traffic load effect and under return perild are obtained. Finally, this load model is applied to the example.
