For the all classes of dies, if we analyse the fluctuate, tendency of increase and decrease and law which appeared in the die's whole life, we will find that the master of the error are changeless; the error that because the abrade of the cutter and impression will be as the cutter grinding times increased at the same time. And that will cause the error oversize gradually; and also have another part error are unconventional , unforeseen.

对各类冲模冲件误差在冲模整个寿命中出现的波动、增减趋向及规律等进行全面分析便可发现：冲件误差的主导部分是不变的；因刃口或型腔的自然磨损而出现的误差增量随冲模刃磨冲数增加而使这部分误差逐渐加大；还有部分误差的增量是非常规的、不可预见的。

本发明涉及一种用于测定植物冠层群体光合作用的冠层叶室，由正方形的光合室和圆柱状的土壤固定体两部分结合而成，冠层叶室下部土壤固定体设有把手，基部为波纹状切口，可以很容易地把固定体插入土壤中形成密闭的冠层叶室，固定体上口与光合室底壁的圆形开口吻合，使冠层叶室的内腔形成一个整体；光合室顶壁用双面胶和光合薄膜密封，以保证光合室稳定的透光性能；光合室侧壁内安装一个小型风扇，由装在侧壁外的电池和开关控制，风扇可使冠层叶室内的气体迅速达到平衡。

Unpumped EDFA has been widely used as a key component in mode-locked in plenty of fiber laser cavity experiments.

利用这个性质，在很多的光纤环腔激光器中，人们可以利用未泵浦的EDFA进行被动锁模，并且得到了大量实验的验证。

The permittivities of N, N-dimethylformamide, water (H2O), and DMF-H2O mixture solution were measured by a resonant cavity perturbation method at 2.45 GHz and 288, 298, and 313 K. The measured results showed a specific phenomenon wherein the imaginary part of the solution's permittivity was larger than that of each of the components.

在288、298和313K三个温度和2.45GHz频率下利用微扰谐振腔法测量N，N-二甲基甲酰胺、水(H2O)及其混合溶液的等效介电常数过程中，发现了混合溶液介电损耗虚部大于其中任一组分的介电损耗虚部的特异现象。

Using the scanning electron microscope, the starch granules were observed which gathering and stuffing in scale cell during bulb development.

用扫描电镜观察到鳞片细胞中明显的淀粉颗粒，并随鳞茎的发育充满整个细胞腔。14C示踪技术分析表明，含苞期的14C-同化物分配以地上部为主，集中在花苞部位；花后期的14C-同化物分配以地下鳞茎为主，其中下位叶标记处理的鳞茎分配量占植株总14C的比例达85.8%，证实了植株的光合产物在花后期主要供应鳞茎发育膨大所需。

By this the system, bovine preantral follicles in different diameters were cultured in vitro;and the effects of the number of follicles in each well of culture plate, different concentrations of NGF, Vitamin E, and Vitamin C on in vitro development of preantral follicles were studied.

在96孔培养板中，每孔25μl培养液的条件下，利用此系统研究了卵泡的入培直径、共培养卵泡数及神经生长因子、维生素C和维生素E对腔前卵泡体外发育的影响。

Sudden death of entanglement between two entangled atoms independently coupled to fields is investigated in two detuning cavities.

在两个腔都失谐的情况下，两个原子分别与两个光场耦合的模型中，研究了初始纠缠的两个原子出现了纠缠突然死亡现象的问题。

In the rat carotid injury model, SM16 dosed once daily orally at 15 or 30 mg/kg SM16 for 14 days caused significant inhibition of neointimal thickening and lumenal narrowing. SM16 also prevented induction of adventitial smooth muscle alpha-actin-positive myofibroblasts and the production of intimal collagen, but did not decrease the percentage of proliferative cells.

在大鼠颈动脉损伤模型中，每日口服15或30mg/kgSM16持续14天能够显著抑制新生内膜增厚及管腔狭窄，预防对外膜α-SMA阳性肌成纤维细胞的诱导和内膜胶原的合成，但并不降低增殖细胞的比例。

How big a macrocycle should be for threading to occur is a basic and important question in threaded structure chemistry.

在互穿结构化学中，客体二级铵盐究竟最小能穿过多大的冠醚环的空腔形成互穿结构是一个基本但非常重要的问题。

Or, how does VEC influence these characters and functions of its neighboring TC. These are all unclear. On the other hand, How does TC adhere to and destruct the vascular endothelium to enter and come out of the vascular cavity during the tumor haematogenous metastasis?

反之，位于TC邻近的VEC对TC的生物学特性、功能又如何影响以促进肿瘤血管系统的建立，尚不清楚；另一方面，在肿瘤的血行转移中TC如何粘附、破坏血管内皮以进出血管腔？

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
