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。

First, the analytical formula of the spheriform water-bearing structures advanced detection in the whole space is deduced. Based on the analysis of large forward modeling results with finite element numerical simulation method, the apparent resistivity data in 3-D space with tunnel is translated into the data of advanced detection in the whole space with comparison method.

首先，推导出了无限全空间中球体含水构造直流电法超前探测的解析解公式，并在利用有限元数值方法进行正演分析的基础上，借助&比较法&将含隧道腔体的三维空间中超前探测视电阻率数据转换为无限全空间中的数据，并探讨了由MN电极附近电阻率不均匀所造成的干扰以及识别和去除这种干扰的方法。

In conclusion, epididymosomes are small membranous vesicles secreted in an apocrine manner in the intraluminal compartment of the epididymis and play a major role in the acquisition of new proteins by the maturing spermatozoa.

总之，epididymosomes是一种小的膜状小泡，以顶分泌的分泌方式存在于附睾管腔中，在精子成熟过程中获取新蛋白发挥着主要作用。

The results showed that the defect was made by the gasbag formed by exhaust obstruction on the head during the injection molding process, and the high pressure and high temperature gas in the gasbag through heat conducting and infiltrating caused some head shining on the surface.

结果表明，该缺陷是由于注塑件本身固有结构造成了在注射成型过程中其头部型腔排气不畅形成气囊，气囊中的高压、高温气体通过传热、渗透影响周围已成型的塑料，从而产生头部皮纹表面局部发亮现象。

The gettering effect of SIM OX intrinsic defects at BOX is much lower than that of the nanocavities. But no Cu are trapped at the rather perfect BOX interfaces of Smart-cut SOI.

在退火温度不高于1000℃时，Al沉淀在吸杂中占据主导地位，在更高的温度下，纳米空腔吸附的杂质量显著上升。

Because the sensors in the electromagnetic field are large, the temperature of the micro hot spot cannot be measured.

但在实际的应用中，对于谐振腔内部的电磁场分布和温度分布的测量是比较困难的，需要将多个感应探头放置于反应场中进行感应测量，而感应器本身的介入对电磁场分布和温度分布就产生了改变，并且宏观的感应器是不可能测试出微观中存在的局部点的过热现象。

In operation, wheel movement causes the shock absorber to force this fluid through small openings.

减震器中充满油液，在行驶时，车轮的运动使减震器中的油液反复流过内腔的孔隙。
