PartⅢThe study of macrography, histology, pathology and apoptosis After the impactive injury of acetabular cartilageObjective To discuss the change of short and long peoriod for the impactive injury of acetabular cartilage by using different energy,the pathological mechanism of chondral injury and the relation between chondrocyte apoptosis and cartilage degeneration. Methods fifty-four New Zealand white rabbits were divided into high energy and low energy groups randomly, of which the two groups which were made through the homemade impactive equipment by impacting the right acetabular cartilage of rabbit at 35cm and 15cm with 0.400kg weight vertically and simulating the mechanism of impactive injury of human acetabular cartilage.

方法新西兰大白兔54只，平均年龄6个月，体重2.5±0.5kg，模拟人髋臼软骨冲击伤机制，采用自制冲击装置，用质量为0.400kg的重锤，分别沿导向杆从高35cm和15cm处下滑垂直冲击兔右侧髋臼软骨，建立兔髋臼软骨冲击伤模型，随机分为高能组和低能组，另一组为对照组，每组18只。

Methods Twenty–four New Zealand white rabbits were divided into model group and control group randomly, of which the two groups which were made through the homemade impactive equipment by impacting the right acetabular cartilage of rabbit at 45cm with 0.400kg weight vertically and simulating the mechanism of impactive injury of human acetabular cartilage. Each group was 12.The model group was injected SH.The control group was injected NaCl solution. The observation of macrography, histology (stained by HE, safarnin O and toluidine blue), transmission electron microscope, scanning electron microscope and the method of TUNEL were made for the three groups that were killed postinjuriously at 4 day and 4 week.

This paper analyses theoretically the take-down function of weight and presser foot, and the cause of the floating up of the fabric edge.

本文从理论上分析了横机上重锤和压脚的牵拉作用和可能产生织物上浮的原因，利用专门设计的压脚装置、口齿-针槽传感器测定了这两种牵位方式的牵拉效果，并分析了实验所得数据和结果，得出了加装压脚装置将有助于牵拉作用的完善的结论。

Free falling heavy rammer was used in former piling constructions, but the piling depth and pile pipe diameter were comparatively small.

在以往的施工中采用重锤下落打桩，打桩的深度和桩管的直径都比较小。

The results are summarized as follows : the number of significance factor increase with the speed, but up to certain speed, the number is invariable; both upper and lower bridles do not affect the net＇ s performance under different speed; while weights and buoyancy are the main affecting factors.

结果显示：显著性因子个数随拖速增加而增加，但到一定拖速后显著性个数不变；在不同拖速条件下，上手纲和下手纲变化对网具性能的影响均不大；重锤和浮力在不同的试验条件下，均是网具性能的主要影响因子。

Ogres are huge brutes, usually using largeclubs or mauls for weapons, and beneath their veneer of stupidity they hide remarkable intelligence in their little head.
