Based on the information taken from the subcompartmental records a comparison between the actual and normal forests was made and a new point of view was proposed in the article: in the case of cultivating timber-forest which is different in cutover age, age class and growing speed within the range of the whole forest station, the forest age class distribution showing the opposite shape of "J" is of more benefit to keeping the relative stability of all the age class area than the age class distribution of th...

本文在统计森林资源小班档案卡片有关资料的基础上，把现实林分与法正林相比较，用法正林学说来指导全场森林的调查。并提出了一个新的观点：在整个经营单位内，培育不同生长速度，不同主伐年龄，龄级期不同的用材树种，森林的龄级结构呈反"J"形分布此法正分布更有利于维持各龄级面积的相对稳定，并且，年伐量的波动不大，有利于森林的永续利用。

Due to the high reliability, high stability and low EMI criterions in auxiliary power supply systems, the half-bridge LLC resonant converter is selected for the front-end converter, the AC bus architecture and full-wave rectifier are as well utilized. The turns-ratio between the AC bus and load converter is 1:1. The effect of beads which are used in the load converters to the resonant circuit is analyzed.

The ADC is pipelined, including a single-input/difference-output sample/hold circuit and nine stage subcircuits. The preceding eight stages are 1.5bits/stage, and the last stage consists of two comparators. Every input sample is converted into 18 bits binary signals, and these binary signals are converted into 10 bits binary signals through digital correction circuit.

We implemented an XTP simulation module running with VINT/NS simulation engine, and an application-level XTP software in Windows environment. We performed analysis and measurement between real implementations. Although the application-level XTP has more implementation overheads than TCP in system kernel, we still have found some inbred advantages in XTP under certain conditions.
