Dead branches or knots in different sizes of tree was studied and different branch development phases of growth,suppression,death and self-pruning was analyzed to evaluate the effect that knot size and distribution impact on timber quality.Branch and knot dynamic models were developed using stand and tree variables.Based on multipleunit stepwise regression method, the individual tree growth model was established using forest and crown factors as the variable. The best taper equation model of Larix olgensis was bucking data of 130 sample trees selected in the studied area.

本研究以不同年龄、不同密度及不同立地条件的落叶松人工林作为研究对象，基于19块标准地中95株标准木的树干解析、枝解析及节子剖析数据，揭示了不同林分条件下林木的枝条数量及在树冠内的空间分布格局、生长发育规律；研究了不同大小树木的死枝和节子大小及其变化规律，分析了枝条的生长、被压、寿命和自然整枝过程，评价了节子大小和分布对木材质量的影响；以林分变量、林木变量和着枝深度等为自变量建立枝条生长和节子大小的动态预测模型；选择林分因子和林木的树冠因子作为竞争因子，用多元逐步回归的方法建立落叶松人工林与距离无关的单木生长模型，并根据研究地区选取的130株造材样木数据，建立了落叶松人工林最佳削度方程。

However,mathematically,self-dual connection one-forms in theEuclidean gravity may not only be real variables,but also be complex(hyper-bolic complex)ones.

然而，从数学上看，欧几里德自对偶联络不仅可以是实变量，还可以取为复变量。

The system implemented forest fire model selection automatically and intelligently. BP artificial neural network model of forest fire model selection was build by treating forest fire environment data as inputting variable and treating appropriate forest fire model as outputting variable. At the same time, we studied the methods of acquiring and calculating data of inputting and outputting. The system implemented machine of model selection automatically based on dynamic data driven technology. We selected 72 items experimental data from historical forest fire records in Beijing to experiment and confirm the validity of model selection. It turned out that the reliability of model selection is more than 80 percent.

Then follows K lines, each of them contains two integers X, Y and character C - coordinates of register inverting point and name of register, which inverts.

再以下K行，每行包括2个整数，1个字符C：表示变量转换的点的坐标，及要转换的变量名。

Since x-coordinate is the low word of lParam and the members of POINT structure are 32-bit in size, we have to zero out the high word of eax prior to storing it in hitpoint.x.

因为x坐标值规定存放在lparam的低字节(16位)中而我们的存放在point结构变量中的坐标值是32位的，所以我们必须用0填充eax的高字节（16位）并把它存贮在hitpoint.x变量中。

In this study, two models to fit soil three-variable characteristic surfaces of different soils were proposed based on the Brooks-Corey soil water retention curve model. Advantages, disadvantages and application conditions of the two were illuminated. In addition, soil three-variable surfaces measured for packed soil samples through centrifuging and controlling bulk density using paraffin material were used to verify the proposed models.

本文在Brooks-Corey土壤水分特征曲线模型的基础上，提出了两种描述土壤质量含水量、吸力和容重三变量关系的曲面模型，分析了模型的优缺点和适用条件，并采用离心机石蜡控容重法实测了四种质地填装土壤的三变量特征曲面。

Since both of the functions reference the same variable, the incrementing and decrementing operations of the two buttons affect the same value rather than being independent.

因为这两个函数都引用了同一个变量，所以这两个按钮的点击会对同一个变量进行增和减的操作。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
