The test results obtained accor- dingly are presented in this paper .Three stopes with different spans (8m , 16m, 24m ) were selected for the purpose of stress study with epoxylite model .

采用环氧树脂模型研究了三种不同跨度(8米、16米、24米)采场，在支护网度为1×0.8米~2及无锚杆护顶时顶板应力分布状况，同时也研了在相同条件下，锚杆支护网度为0.8×0.8米~2、1.6×0.8米~2时顶板应力分布状况，从而阐明了锚杆支护的实际效果。

Field-tests show: grouting bolt exists the question of effective anchorage length; shear stress distribution is disuniform and concentrated in the front 1/3 of the fixed anchoring part.

在现场对普通拉力型锚杆进行了试验，试验表明注浆锚杆存在有效锚固长度问题，沿锚固段全长锚杆与浆体间剪应力分布极不均匀，主要集中在锚固段的前1／3。

On the basis of fivebar pantograph configurations with generating similar curves, the loop augmentation method is used to synthesize the configurations of movable planar seven-bar zero-degree-of-freedom and eight-bar negative-degree-of-freedom overconstrained chains with prismatic pairs.

文中以平面五杆缩放机构为基本架构，利用其产生相似运动曲线之特性，配合回路增殖法，分别合成出自由度为0之七杆与自由度为-1之八杆可动呆链之构形。

The cells of isolate (CW2) stain Gram positively, the morphology of the cells of isolate was changed from rod to round in the process of growth, the cells in the initial phase of logarithmic growth were long rod, majority of cells singly existed, minority of cells were geminated or formed a long discontinuous chain, until to invariable phage of growth, the cells changed to globe.

分离出的菌株CW2为革兰氏阳性，在生长过程中细菌细胞的形态有球杆的变化，在对数生长期的初期细胞是直杆或者弯杆状，大多数单生，少数成对或者成不连续的链状，到恒定期变成类球形细胞。

While the worm surface is generated by contact lines of the generant traditionlly.

计算结果表明，在双自由度运动下，母面无论是直线，平面还是圆弧面曲面，，包络加工蜗杆的过程都是点接触形式，蜗杆表面都是由接触点生成；而在传统上，蜗杆表面都是由母面上的接触线生成。

We have developed a method for detection of Hypodermal and hematopoietic necrosis baculovirus by polymerase chain reaction.

皮下和造血器官坏死杆状病毒［1］、对虾杆状DNA病毒［2］和白斑杆状病毒［3］是近年来引起全球对虾暴发性死亡的病原。

This paper gives some analysis of the working process of the screw compressor with economizer, separates it into three stages: quasi-compression process of the low stage, charge-compression stage, and quasi-compression process of high stage, sets up the mathematical models and its solution of the actual process. The capability increscence of the screw compressor with R717 and R22 after using the economizer has been calculated.

在分析带经济器螺杆制冷循环系统工作机理的基础上，本文着重分析和研究了压缩机的工作过程，把带经济器螺杆制冷压缩机的工作过程分成&准低压级压缩&、&充气——压缩&、&准高压级压缩&三个阶段，并提出了反映该循环实质的数学模型，给出了求解方法，计算了R717、R22两种常用制冷工质的螺杆压缩机在带经济器后的性能增长情况。

The sub-problem optimal way is used to optimize the mutual insert multi-span greenhouse and the optimal result is disposed using iterated algorithm. Through repetitious iterative disposing the optimal result of three kinds of loads to the mutual insert multi-span greenhouse, it is acquired that the arch pipe's diameter is 32mm, the knighthead's diameter 20mm, the mutual distance 60cm and the gradient side pole's horizontal projection distance is 50cm.

采用零阶优化方法对互插式塑料温室的优化计算结果进行多次迭代处理，得到3种工况下的优化结果：拱杆直径为32mm；支撑杆直径为20mm；互插间距为60cm；倾斜侧杆的水平投影为50cm。

The homologues of ptp-1 and ptp-2 genes were found in some lepidopterous baculoviruses, but not in non-lepidopterous baculoviruses. ApNPV was one of the four baculoviruses contained both ptp-1 and ptp-2 genes.

只有部分鳞翅目杆状病毒编码ptp-1、ptp-2基因同源区，非鳞翅目杆状病毒不编码ptp-1、ptp-2基因同源区，而ApNPV为鳞翅目杆状病毒，同时编码ptp-1、ptp-2基因同源区。
