By producing pseudorandom number series, we rectify the power spectrums of normal random inputs in the same shape as power spectrums of simulating signals. Through Laplace transformation, we can acquire the frequency response functions of rectifier. Two simulating examples were presented. The power spectrum curves based on one peak function model were almost coincided with the power spectrum curves of simulating loads shown in the figures. Simulating results of input loads had good accuracy. Creating a simulating method and program of input load in this paper was effective.

deferred tax 递延税项（指因为采取不同会计原则而造成实际应税所得和会计利润不等的情况，最常见的情况就是根据税法采取加速折旧法，而为了报表好看又采用直线折旧法，这样造成的税差就作为负债出现。

Methods 142 male peelers and 107 male operators were conveyed with the questionnaire of generic job stress commended by Yu Shanfa, and blood pressure ,heart rate, ECG ,blood sugar, glycerinate, cholesterol, monoamine neurotransmitter were detected meanwhile.

采用余善法教授推荐的工作紧张问卷对某市公安局刑警支队和巡警支队的全体干警进行紧张调查和健康状况检查，检测血清中单胺类神经递质、血糖、血脂水平，检查血压、心率、心电图等，并进行方差分析及两两比较。

At the every relative momentary point of time time-space, the situation of difference spatial measurement of cosmic gravitation exceed cosmic space-energy follow the rise and fall of quantum spatial measurement, at original cosmic time-space set out, from 0 come to do not exceed the 1/2 spatial measurement of cosmic time-space, not smaller the 1/4 spatial measurement of cosmic time-space, come to do not symmetrically gradually belong to stabilization thus at reductively fluctuate, not can reversely strides across reach the stable state of 1/3 spatial measurement cosmic time-space maintain unchanging.

在时空时间的每1个相对时刻点，宇宙引力大于宇宙空间能的宇称差的状况随宇称量子的涨与落，在原初的宇宙时空启动，从0成不大于宇宙时空宇称的1/2，不小于宇宙时空宇称的1/4，成不对称地递归于稳定而在缩小地波动，不可逆地跨越到宇宙时空宇称1/3的稳定状态保持不变。

Re-vectorization is performed on the basis of original vectorization by obtaining the initial parameters such as line types and slope. Inuring tricing it can adjustthe parameter adaptively. To decrease the influence of noise pixels, we designed a stop probe to detect tracing-stop conditions. Process of re-vectorization is performed recursively until quality of graph entity is satisfactory.Finally, some key technologies for 2D graphs reconstruction are studied. The issues concerned include the recognition and presentation of topologic relations among graphs entities and a directed and weighted graph model established to describe the relations and techniques on dimension driven.

在获得对图素识别质量的评价之后，质量较差的图素被输入到错误自动校正器进行错误校正处理，本文提出&二次矢量化&的错误校正思想，二次矢量化是在初步矢量化所获得知识的基础之上，取得初始参数，并在跟踪过程中动态校正参数，在跟踪结束时引入跟踪终止检测探针以消除光栅图像中黑白噪音的影响，使得算法具有较强的抗噪音干扰能力，校正后的图素仍需进行质量评价，未能通过评价的图素需递归执行二次矢量化算法。

From this phenomenon, the former syndiospecific ends symmetric go poorly in mechanical, on the one hand feeding reasons, on the other hand is between one paper feeder teeth.

从此本体看，后规两头不不差称行不到位，在板滞上，一方面是输纸来因，另一方面是递纸牙叼纸来因。

However, the estimation results show that most estimated values are not statistically significant. According to the Burgstahler and Dichev (1997), Mills and Newberry (2001), and Phillips, Pincus, and Rego (2003) studies, this study tries to examine whether the income tax expense/benefit has the ability to forecast the earnings management by using the temporary differences between GAAP and tax law while under the control of non-discretionary accruals and tax incomes.

延伸Burgstahler and Dichev(1997)、Mills and Newberry(2001)及Phillips，Pincus，and Rego(2003)的研究，本研究试著由GAAP与税法规定同所产生之暂时性差入，在影响课税所得的情况，并控制非裁性应计项目后，检定递延所得税费用/是否对盈余管有预测能。
