Ecological characteristics:Seedlings of the tree grow vigorously in the spring with maximum height incensement in early May and a simulated growth of sigmoid shape during the growing season.

生态学特性，彰武松是属于春季生长类型的树种，其苗高累计生长呈S型曲线，全年最大生长量出现在5月上中旬；地径开始生长比高生长晚10d左右，全年出现两次生长，其中以春季生长为主；主根的生长和地径的生长交错进行，和苗高生长基本同步。

The results were as follows the change of vitamin C content was a "trial apex"-shape curve, higher in young fruit,incrustation and maturation stages, lower in other periods; the total acid content was the highest in young fruit, after that, it decreased rapidly, maintained lower level, and reached lowest when the fruit matured; the total content of soluble sugar inosculated with the fruit development, it was high when the fruit development was quick, and low when the fruit development was slow; before 59 d after anthesis, the reducing sugar content was high in the total content of soluble sugar and after that ,the nonreducing sugar content was high; before 45 d after anthesis, free amino acid content was obviously correlated with protein content, and they inosculated with the fruit development;4559 d after anthesis, free amino acid content increased quickly, and protein content decreased gradually, this was also the most shaping period of the embryo and endosperm.

结果表明，Vc含量呈&三峰&型曲线，幼果时、硬核后和成熟时较高，其他时期较低；有机酸含量以幼果期最高，以后迅速下降并维持较低水平，果实成熟时含量最低；可溶性总糖含量与果实发育状况基本相吻合，果实发育速度快时含量较高，慢时较低；在谢花后59 d以前，可溶性糖以还原糖为主，之后以非还原糖为主；游离氨基酸和蛋白质含量，在谢花后45 d以前两者呈高度相关，且与果实生长速度相吻合，谢花后4559 d是胚和胚乳的主要形成期，此期游离氨基酸含量迅速增加，蛋白质含量持续下降。西北林学院学报21卷第5期张传来等金光杏梅果实发育期间主要营养成分动态变化研究

Most of hob design for non-involute gears are nowadays taken by approximation method.For example,the normal sectional profile of hob worm therad is usually regarded approximately as its basic rack profile.Recently, some new methods have been developed in this respect but, perhaps, they appear overelaborate since the principle of spacing engagement is based on. For this reason , the paper offers a new design procedure for hob worm based on the planar engagement principle with the intention of simplific...

本文应用平面啮合原理精确设计各种非渐开线齿轮滚刀的基本蜗杆，提出并应用啮合线的投影原理从工件齿轮端截面的啮合线直接求得刀具蜗杆的端面齿形，而不必求出媒介齿条的齿形，方法很简单，还从啮合线的投影原理简明而形象地证明了一对螺旋齿轮直接啮合过程的啮合线是一条垂直于齿向的平面曲线。

Profilograph, fundamental roughness ruler and multirange roughness ruler have obvious advantages, which can be used as effective methods in the directive statistical research of JRC.

轮廓曲线仪、基本粗糙度尺和多量程粗糙度尺具明显的优越性，为JRC定向统计研究提供了有效的手段。

The signal transfer function is considered as the most basic and important parameter to evaluate the characteristics of the infrared thermal imaging system,and is the linear portion of the responsivity function.

信号传递函数是评价红外热像仪性能的最基本且最关键的技术指标之一，它是响应度函数的线性部分，从响应度函数测试曲线中可得到待测系统增益、线性度、动态范围和饱和度的信息。

The testis index, testis volumes were same as the annual changes of testis mass. The curves of annual variation were all unimodality.2 The spermatogenetic cycle of Myospalax cansus comprises seven stages with significant features: Stage I , from February to April, the testis were at the stage of spermatogonia proliferation. In this period, testis index and the number of spermatogonia began to rise. Other spermatogenic cells had not yet formed; Stage II to III, from March to April, primary spermatocyte meiosis period. The testis index was highest in this stage, and spermatogenic cells were in spermatocyte stage, the primary spermatocyte meiosis generated to secondary spermatocyte; Stage IV, from April to May, spermatocytes continued to split, germ cells appeared in seminiferous tubules; Stage V, in May, sperm formation, spermatids of seminiferous tubules were transformed to spermatozoa, a large number of sperms existed in the lumen; Stage VI, spermatozoa emission period, from May to June, testis index were a significant drop and mature spermatozoa excluded gradually; VII, the testicular activity ceased basically from July to September, November to January of the following year, the spermatogenic activity ceased completely. Therefore, Myospalax cansus are animals of seasonal reproduction, spermatogenesis cycle is discontinuous type.

睾丸系数、体积和重量的年周期变化规律一致，变化曲线呈现单峰型。2甘肃鼢鼠雄性生殖腺的年周期活动由7个特征明显的时期构成：Ⅰ期，2～3月份，精原细胞增殖期，睾丸系数开始上升，精原细胞进行有丝分裂，其他生精细胞尚未形成；3～4月份为Ⅱ～Ⅲ期，初级精母细胞成熟分裂期，睾丸系数达到最大，生精细胞大多处于精母细胞阶段，初级精母细胞减数分裂生成次级精母细胞；Ⅳ期，4～5月份精母细胞继续进行分裂，精细胞在生精小管内出现；Ⅴ期，5月份，精子形成期，曲细精管中精细胞变态成精子，在管腔中存在大量的精子；Ⅵ期，精子排放期，5～6月份，睾丸系数显著下降，成熟精子从生精小管上脱离，逐渐排除；Ⅶ期，精原细胞停滞期，7～9月份睾丸生精活动基本停滞，11～翌年1月，生精活动完全停止。
