Regression analysis gives management accountants an objective measure to use in evaluating the precision and reliability of estimations.

It is important to prepare a graph of the data prior to using regression analysis and detennine whether any unusual data points, called outliers, are present. Regression analysis can be influenced strongly by out1iers, which may result in an estimation line that is not representative of most of the data. If present, each outlier should be reviewed to determine whether it is due to a data recording error, a normal operating condition, or a unique and nonrecurring event. Regression analysis requires a collection of data points-preferably 30 or more一to be accurate.

Regression analysis assumes a linear relationship between one dependent variable and one or more independent variables. In the case of analyzing cost behavior, this linear assumption can be problematic if it is expected that costs decline due to leaming curves (see the discussion of leaming curves later in this topic) or when there are different relevant ranges of activity that cause costs to shift.

Regression analysis also assumes that past relationships between dependent and independent variables will hold into the future. When using regression analysis as a forecasting tool,it is important to evaluate or make adjustments for changes in the relationship between the variables over time. For example， if there is clear knowledge that one part of a variable cost element is increasing, this makes the b coefficient less reliable for future periods.

When using the results of a regression analysis to make any prediction, it is important to remember that the dependent variables used for the prediction must fall within the range of the data set used to establish the regression line. For the Build and Fix sales and marketing costs, the marketing costs used to estimate the regression line fal1 in the range of $30,000 and $11 0,000. The company can reliably predict its sales for any marketing cost that falls within this range but it cannot rely on the resu1t if the marketing cost used in the prediction falls outside this range (e.g., $10,000 or $200,000).

One caveat regarding regression analysis is that the user must evaluate the reasonableness ofthe relationship between the dependent and independent variables. Does it make sense that X causes Y to change? Any numbers can be input as X and Y var?ables and wi11 result in an equation, but whether the equation makes sense must be based on the user's judgment.

3.3.4 Although ESP is a high-collecting equipment, but the efficiency of collecting and collecting a plate area of exponential curve relationship. One of the three field electrostatic precipitator, the electric field in the first 80% - 90% efficiency in collecting, and Dier San electric field only to gather dust concentration of 10% -20% lower than that in order to achieve 50mg/Nm3 The concentration of low-emission, or electric field Disi Wu need to be created in the electric field in a significant increase in plate area.
3.3.5 single kiln kiln operation and a joint ground operation convert each other, the entrance Filter dust conditions (gas, temperature, concentration, moisture content, resistance, dust particle size, and so on) there is a greater change, often exceeding emissions .
3.3.6 The design of the existing electrostatic precipitator dust 99.875% efficiency, this calculation, in the normal process conditions, can only meet the emission of dust 100mg/Nm3 less than the requirements of dust emissions to less than 50mg/Nm3, Xinhua close The dust-collection efficiency must be greater than 99.94 percent.
3.3.7 The production line put into operation early days of back-end electrostatic precipitator emissions standard will be replaced by silicon high-voltage power supply source of cross-flow, but the effect of the use of the electrostatic precipitator has been unsatisfactory, the original equipment set up ten-speed manual adjustment Stalls in the campaign, the number of open stalls in a process can only be adjusted under the best of the stalls, not with the technology changes and regulation at any time, the impact of collecting results in the actual operation can only be the largest transfer Six to file.
According to the electric field area, high-voltage rectifier cabinet should be selected Current rating 1600mA, but for the actual 1500mA, small selection of models.
In addition to the performance of electrostatic precipitator with the structure, to a large extent by the performance of dust and operating conditions. The main factors: the dust resistance, the concentration of dust, particles of dust, gas composition, temperature, humidity, air leakage, such as the collecting. In cement production, the ever-changing state of technology, raw materials mill open, listening, the conditioning tower in a timely manner can adjust the volume of water can filter from the excessive emissions.

凸轮是一种常见的、用途广泛的机械装置。它仅由两个部件组成。输入件是凸轮本身，输出件称为随动件。通过使用凸轮，简单的输入运动可以修改成几乎任何你能想到并且所希望得到的运动。下面是凸轮常用的一些场合:
1. 汽车发动机的凸轮轴和分电器轴;
2. 生产机械;
3 .自动电唱机;
4. 印刷机;
5. 自动洗衣机;
6. 自动洗碗机;
7. 包括电脑在内的计算机器.

凸轮是最通用的机制。凸轮是一个简单的两名成员组成的装置。输入成员凸轮本身，而使用的成员被称为从动件。通过使用凸轮，一个简单的输入运动可以修改成几乎任何可以想象的出，是理想的运动。一些常见的应用凸轮：（1）汽车发动机凸轮轴和轴；（2）生产工具机；（3）自动记录玩家；（4）印刷机；（5）全自动洗衣机；（6）自动洗碗机；（7）计算的机器，包括电
