For example, Complete tree method and negative boot active tree method, front exist symbol distinguish issue, the latter follow exist redundant term. Chen W.

其后，黄汝激提出了正负根有向树法，并给出了完整的证明，使其兼有完全有向树法和负根有向树法的优点：不含对消项，不存在符号问题。

Starting with a discussion of the coradical filtration of pointedcoalgebras in the second chapter,we give a vector space comple-ment of Cn?

首先从pointed余代数的余根滤链的结构出发，本文第二章给出了余根滤链Cn？

For each layer-divide symbol appeares regularly in weave diagram, the layer-divide symbol is affirmed first,then the attribute of each yarn and weft is fixed,the weave of each layer is analyzed at last. As to leno fabric, the reverse side of the fabric should be analyzed, tell the crossing warp from normal warp before drafting the looming draft.This paper introduces the method to analyze this kind of complex fabric through above two examples.

对四层织物分析时，找出组织图上有代表性的组织点的属性，因分层符号在组织图上出现时很有规律，可以先确定各层分层符号的位置，进而确定各根经纬纱的属性，分出各层织物，最后分析各层的组织；纱罗织物分析时，应分析织物的反面，先要区分出绞经和地经，然后才能绘出组织图。

Then he took a second rope -- one used to tow cars, with large hooks at both ends -- and hooked one end to a loop on the guide rope. He wound the other end around a poplar and hooked the tow rope onto itself.

然后他拿出另一根绳，一根两端带有大钩子，通常用来拖车的绳，一端钩在导索的搭环上，另一端缠绕过一棵杨树后和这个拖绳本身钩在一起。

For any semigroup-graded ring R= R_ x, the constructions of graded strongly prime radical and graded generalized nil radical of R are given.

对于半群分次环的分次强素根和分次广义诣零根，分别给出它们的构造。

When dry distillation of distillates by condensation, the liquid product of clarification, it is submerged in the lower pine root oil, pine root oil and then use the same method can be obtained for further processing pine tar.

干馏时的馏出物经冷凝后，液体产物澄清时，沉在下层的是松根油，再将松根油用同样方法进一步加工可制得松焦油。

The scion and radicle had different response to the salts, and the salt concentrations had more influence on the radicle.

幼根和幼芽对不同种类盐胁迫表现出不同的反应，盐浓度对根的影响较大。

Some of Hazel Perfect's results on positive stochastic matrix with real characteristic roots are applied to the quasi-stochastic matrix with known characteristic roots is given.

又把Hazel Perfect对于随机矩阵实特征根的理论，推广到拟随矩阵，最后给出一个已知实特征根求拟随机矩阵的方法。

This invention relates to a method and device for generating cold atomic beam. Said method includes heating hot atom source in vacuum chamber to form atomic saturated vapor pressure atmosphere, cooling hot atom by three-D MOT to below 200uk and trapped to form cold atomic cloud, by the quarter wave plate reflection mirror in MOT the laser radiation pressure being unbalanced to make cold atom emitting along said direction, four tape arranged straight line set with contrary current direction is set in atom beam emission direction, which makes the atom emitted to forward to obtain cold atom beam with low speed, large flux and small transverse speed, laser beam vertical with atom beam set in the direction of cold atom emitting for atom beam state preparation to realize state concordant emitted cold atom beam.

本发明涉及一种冷原子束产生方法和装置，该方法包括在抽真空的真空室内，加热热原子源，在真空室中形成相应的原子饱和蒸汽压气氛；采用三维MOT对热原子进行冷却，冷却到200μk以下，并被捕获形成冷原子云团；通过三维MOT中开小孔的四分之一波片反射镜，而使得在该方向上激光辐射压力不平衡，使冷原子沿此方向出射；在冷原子束出射方向上，还置有载有彼此电流方向相反的四根成锥形排列的直导线，从而原子出射时将在磁场的作用下，不会沿横向膨胀而向前射出；便得到了出射速度低的、通量较大的、横向速度非常小的连续冷原子束；同时在冷原子束的出射方向上，设置有与原子束垂直的激光束，用于原子束的态制备，实现态一致的出射冷原子束。

Hypha and arbuscular colonization have same orders in the two breeds, fastigium occurred in summer and low occurred in late spring and early summer, spore peak produced in summer in the Rhizospere of Puerraria lobata. Spore density had positive correlation with abuscular colonization, the minimum value appears in the winter, and the maximum appears in the summer; consist with the growth prosperous of lobata.

菌丝与丛枝定殖率在两品种间变化规律基本一致，高峰期都出现在冬季，低峰期则出现在春末夏初，夏季为葛藤根区AM 真菌的产孢高峰期，孢子密度与丛枝定殖率呈正相关，最低值出现在冬季，最高值出现在夏季，与葛藤的生长旺季相一致。

Fancy gold-plated dangling earrings with facetted White Opal crystals.
