然而,目前,Pd纳米立方体的合成机理并不明确,特别是卤素离子(Br-和I-)在合成过程中的作用。基于此,本论文从实验以及理论上系统地研究了 Pd纳米立方体形成机理,并在此基础上,研究了 Pd纳米立方体向PtPd双金属转化行为。 具体内容如下:(1)以PdCl42-为前驱体,聚乙烯吡咯烷酮(PVP)为保护剂,乙二醇(EG)为还原剂,通...
-i dev --interface dev ptpd 実装に使用するインターフェースを指定します。例えば、en0 になります。このフラグは、ptpengine 属性を次のように設定します。 ptpengine:interface -k --check-config PTP 構成と出口を検査します。構成が正しい場合は 0 を返します。 -l file --lockfile file ...
*日期的核心算法 1、计算本月有多少天 2、本月的第一天是星期几 3、用本月第一天的星期数W+总共天数T 最后得到一个总数WT 用这个数来做循环控制量,let(let i=0;i<WT,i++)如果在i<W,往数组push[0],如果i>W,则计算号数 n=i-W+1;数组添加push[n] 4、把这个数组按7,分成二维数组就可以了,这个...
-i dev --interface dev Specifies the interface to be used for ptpd implementation. For example, en0. This flag sets the ptpengine attribute as follows: ptpengine:interface -k --check-config Checks the PTP configuration and exits. Returns 0 if the configuration is correct. -l file --lockfi...

1, 09/2018 Implementing an IEEE 1588 V2 on i.MX RT Using PTPd, FreeRTOS, and lwIP TCP/IP stack 1. Introduction Contents This application note describes the implementation of the IEEE 1588 V2 Precision Time Protocol (PTP) on the i.MX RT MCUs running FreeRTOS OS. The IEEE 1588 standard...
I am trying to port a ptpd example written for the stellaris ek-lm3s8962 (stellarisware) into tivaware. Obviously the differences on how PTP1588 is implemented on the tiva processors these have to be reflected on the software as well. As one ...
