Since the weight of a basket hilt or counterweight counts towards satisfying the requirement, fighters can and do make swords which have light blades and heavy hilts; such swords handle quite differently from real medieval swords, which are typically blade heavy.

由于重量与一篮子的Hilt或抗衡计数对满足要求，战机可以做，使刀剑，其中有轻型和重型刀片hilts ；刀剑等处理相当不同，从真正的中世纪的剑，这是典型的叶片沉重。

Two specieses, Lycoris radiate and Lycoris aurea, were selected for the studying of artificial propagation in vitro. A few specieses of Lycoris, from the southeast area of China and part of locations in Japan, were chosen to research their karyotype differentiation and to measure their genetic diversity by ISSR analysis. The results could be summarized as follows.1. The vegetative propagation conditions of Lycoris aurea and L. radiate in vitro was studied by two-scaling. Different illuminate condition had an effect on the bulblet formation rate. To the species of L. radiate, the rate was higher in the state of 16h 800-12001x illumination than in the darkness. The medium also affected the new bulblet formating rate. When the culture was MS medium 0.2 mg/L NAA 4 mg/L 6-BA, the bulblet formationg rate of L. aurea was 220%;at the same time, when the medium was MS 0.2 mg/L NAA 2 mg/L 6-BA, the rate of L.

本研究选择西南部分地区及日本的几个石蒜品种，从细胞学和DNA分子角度，分析了它们的遗传多样性水平和遗传结构状况，对红花石蒜和忽地笑的离体繁殖技术进行了初步研究，得出如下结论： 1 进行了红花石蒜和黄花石蒜双鳞片快速繁殖条件的研究，结果表明：红花石蒜在16小时800-1200 lx光照下比黑暗条件下出芽率要高；黄花石蒜在MS NAA0.2mg／L 6-BA4mg／L下出芽率为220％，红花石蒜在MS NAA0.2mg／L 6-BA2mg／L下出芽率为108％；NAA比IBA有利于石蒜生根；硅藻土显著提高黄花石蒜双鳞片出芽率，活性炭起抑制作用；6％蔗糖浓度有利于红花石蒜小鳞茎增重，MS 6-BA4mg／L NAA0.5mg／L培养基有利于小鳞茎增殖，切割一刀比两刀有利于小鳞茎增殖。

The relationship between unit amount of feed and transmission ratio of planetary gear train was analyzed.

针对多头多刀锁盖机构，详细讨论了多刀锁盖机构的行星轮系传动比等参数对锁盖质量的影响，分析了传动比与进给量的关系。

The second: half-step, this can be called up before and after the nemesis ofthe step-by-step, as long as you maintain a good distance of about 5, the semi-circular for his slow progress, because beforeand after step to the lack of flexibility, as long as he steps before and after Not in a row, he will be very difficultFlying, then you can use light to deal with the knife he had.

第二：半圆步，这个步伐可以称为前后步的克星了，只要你把距离保持好5步左右，对他进行半圆形的缓慢前进，因为前后步缺乏灵活的转向，只要令他前后步走不连续，他就很难飞刀了，这时你就可以用轻刀来对付他了。

To investigate the basic physiological data of saury Coilia ectenes, which were collected from the Changjiang River of Anqing in Anhui, the swatches were fixed using Bouin's solution, and developmental condition of the gonad was observed.

在长江的南通及安庆江段捕捞刀跻样本，对样本进行各种常规生物学数据的测量，并对解剖标本的性腺用Bouin氏液进行固定保存后，将性腺制作成组织切片，通过切片观察，了解徊游至南通及安庆江段的刀鳞性腺发育的状况。

Based on the hierarchical express of tool and workpiece, overlapping test between OBBs and octants of the surfaces octree with the separation axis theorem is implemented.
