查询词典 reference number

The invention relates to a method for synchronizing at least one node of a bus system, which is operated with a predeterminable system clock period, whereby a local clock period and a reference clock period are given for the at least one node, and the reference clock period is synchronized with the system clock period. A local clock period, which is synchronized with the system clock period, of the at least one node is produced whereby linking the local clock period with a splitting factor, whereby the splitting factor represents a ratio of the reference clock period to the local clock period. The splitting factor for synchronizing the local clock period with the system clock period is adapted by adding or subtracting a adaptation value.

Common rolling plank is shown intense (orientaton of 0002) tool reference plane, after rolling of horn waiting for diameter, plank grain orientaton by original (change of orientaton of 0002) tool reference plane is; of orientaton of blame tool reference plane the existence after strain crack of common rolling plank is many twin brilliant, amount of brilliant of twin of drawing of direction of rolling of edge of plank of rolling of horn w

普通轧制板材呈强烈的(0002)基面取向，等径角轧制后，板材晶粒取向由原来的(0002)基面取向转变为非基面取向；普通轧制板材拉伸断裂后存在大量孪晶，等径角轧制板材沿轧制方向拉伸孪晶数量明显减少，等径角轧制有可能启动了新的滑移系，而拉伸孪生只是作为一种协调变形机制。

The chapter 3 investigates the constructive method which means that many combinatorial numbers, such as Stirling number, Bell number, harmonic number, Fibonacci number and the number of derangement, are represented to moments of some random variables. This method is used in the computation of combinatorial sums, discovery and proof of combinatorial identities.

第三章研究了构造性概率方法，即一些常见组合变量(以后统称组合数为组合变量)的概率表示，诸如Stirling数、Bell数、调和数、Fibonacci数、错排数都可以表示为一些随机变量的矩，这些概率表示可以用来研究组合和式的计算与恒等式的证明。

First, let's consider the number seven: In mathematical terms, it is an irrational number, i.e., a number that cannot be represented as a simple fraction, a number that is "uncountable." To the mind of the symbolic thinker, the number is associated with all that is strange and unusual.

首先，让我们认识一下数字7；在数学上，它是一个无理数，也即除以它的结果不能得到一个单一的数字，除以这一数字将得到一个无穷数列，对一个符号象征思想家的内心来说，这个数字会让人联想到所有古怪的，不寻常的事物。

It is shown that maximum temperature value of the field's will rise while the Mach number increases. After the Mach number exceeds one, a clear bowshock is obtained in the simulation result, and the Mach angle decreases along with the Mach number. Those are consistent with theoretical results. While the Mach number is 3.5, even the radome inside is adiabatic, the maximum temperature is below 1000K. So the CVD diamond thick film radome can meet practical requirement of flight at 3.5 Mach number.

研究发现，随着马赫数的增加，温度场中最大温度值也随之增大；在马赫数大于1时，会产生明显的弓形激波，且激波的锥角随马赫数增加而减小，这与理论结果相一致；当马赫数为3.5时，即使在头罩内壁绝热条件下，温度场中最高温度值也在1000K以下，表明CVD金刚石厚膜可以满足Ma=3.5的实际飞行要求。
