富镧稀土对水稻的增产效果及应用前景

镧(lan thanum,L a)作为稀土元素之一,在有机体内含量很少,但对生命活力具有重要的调节作用。水稻在不同生长期喷施适当浓度的镧元素,分蘖速度加快5%~30%,抽穗提早,实粒数、结实率、千粒重明显提高。富镧稀土的作用机理主要是提高植物体内多种酶的活性,促进化合物的转化,增强呼吸强度和生理代谢作用,从而促进了植物的生长发育。     

思茅松人工林断面积蓄积量标准表的编制

为了编制思茅松人工林断面积蓄积标准表，在思茅地区、西双版纳州收集人工林标准地165块、标准木561株。经4个模型选优，最后确定了表达式，据此编制了思茅松人工林断面积蓄积标准表。     

红松干栖真菌群落结构(Ⅳ)

运用真菌学、森林病理学与群落生态的基本研究方法，对红松干 真菌群落结构进行研究，经分离培养获得干栖真菌４０属（种）、干栖真菌群落的种群组成种类类随着红松干部高度的升高趋于减少，在健康红松下冠层的老枝上分离获得了流获得了流脂溃疡病病原菌，表明该病害是潜伏侵染性病害。     

草地休牧、禁牧期家畜饲草供给模式探讨

针对内蒙古奈曼旗草地休牧、禁牧期草食家畜可利用饲草数量不足、质量较差、利用率偏低的问题，通过试验示范的方式推广了天然草地围封改良、补播改良、优质混播人工草地建植、高产饲料地建植等适用增产技术和青贮、微贮处理技术等提高饲草利用率的措施。综合考虑当地舍饲家畜畜群变动规律、饲草需求特点以及各类饲草资源的供给时间特性，分别提出适合全年禁牧和季节性休牧条件下草食家畜饲草均衡供给模式。

A comparison of knot security of commonly used hand-tied laparoscopic slipknots

OBJECTIVE: To compare the peak force required for failure of hand-tied laparoscopic slipknot ligatures. STUDY DESIGN: In vitro mechanical evaluation of suture material/knot combinations. Sample POPULATION: Four hand-tied laparoscopic slipknots were studied. Three suture materials and 2 suture sizes were evaluated. Twenty samples of each group were tested, for a total of 400 samples. METHODS: The 4S modified Roeder, modified Roeder, and Weston and Brooks laparoscopic slipknots using 0 polyglyconate, 0 polyglycolic acid, 1 polyglyconate, and 1 polydioxanone (PDS) were tested. A vertical distracting force (5 mm/s) was applied until failure. Mean peak force to failure was obtained for each suture material, size, and knot combination. RESULTS: Mean (+/-SEM) peak force to failure of hand-tied ligatures ranged from 156.8+/-9.1 N to 4.8+/-.4 N. The 4S-modified Roeder had the highest mean peak force to failure. Ligatures tied with polyglyconate and size 1 suture had the highest mean peak force to failure. CONCLUSIONS: The 4S-modified Roeder was significantly and consistently stronger than the other slipknots. Polyglyconate was superior to other suture materials. The 1 polyglyconate had the highest mean peak force to failure followed by 0 polyglyconate that exceeded the 1PDS. CLINICAL RELEVANCE: The 4S-modified Roeder slipknot using 1 polyglyconate has the greatest breaking strength of sutures tested and should be considered when performing laparoscopic ligatures.

Five-Strokes Encoding Recognition of Unconstrained Handwritten Chinese Character

Keyboard input techniques are introduced into on line recognition of Chinese character with the study of chinese character five strokes encoding keyboard input method,and a new approach for on line recognition of unconstrained handwritten Chinese character,Five Strokes Encoding Recognition,is proposed.Besides,the set of character roots of Five Strokes have to be altered slightly to meet the on line recognition technique's features.
