恒定

The crus breve incudis is an important marker for operation. The anatomical position of PE is constant. The depth of PTC affects the procedure for cochlear implant surgery via mastoid process-facial recess approach. The location of vestibular window and the round window is relatively stable, so the stapes head can be used as a reference for drilling scala tympani.

结论砧骨短脚是手术的重要标志；锥隆起解剖位置恒定；后鼓室的深浅对该进路的人工耳蜗植入手术的难易程度有重要影响；前庭窗与圆窗的位置关系相对稳定，因此镫骨头可作为参照标志来确定鼓阶钻孔的位置。

The simulation results show that the difference between actually picture coded bits and picture target bits can be minimized by monitoring the "virtual buffer" state to adjust the quantization scaling factor, and thus more stable picture quality can be achieved at a fixed rate.

结果表明，码率控制通过监视"虚拟缓存器"状态调节量化尺度因子，能保持实际帧编码比特数与预分配帧编码比特数一致，从而在恒定码率下，获得均匀的图像质量。

Results (1)The agger cells existed in 99% of the cases, the development of the agger cells in 9～16 years old children, and adult had no difference;(2) The morphology of agger cells differed widely, but its relationship to the anterior border of the middle nasal concha, bulla ethmoidalis and nasolacrimal canal was quite stable;(3) The upward pneumatization of the agger cells was not related to deviation of nasal septum, but closely related to the development of the frontal sinus;(4) The anterior nasosinusitis often influenced the agger cells and might result in hyperosteogeny.

结果 ①绝大多数病例（99%）有鼻丘气房，儿童（9～16岁）鼻丘发育与成人相比无差异性；②鼻丘形态变化很大，但与中鼻甲前端、筛泡和鼻泪管的关系是恒定的；③鼻丘向上气化程度与额窦发育关系密切，鼻中隔偏曲对其发育无明显影响；④前组鼻窦的广泛炎症易波及鼻丘，并可出现鼻丘骨质增厚。

Studies on preparation of ultra-micro spice powder of Daokou Carbonado flavor by freeze grinding technology;2. Studies on supercritical CO_2 extraction of spice blends of Daokou Carbonado flavor were carded out in this paper.

在 CO_2流速和分离压力恒定的条件下，通过单因素和正交试验探讨了萃取压力、萃取温度、萃取时间、分离温度四个参数对本公司开发的道口烧鸡风味复合辛香料进行超临界 CO_2萃取的影响，并确定了最佳提取工艺：萃取压力30MPa、萃取温度50℃、萃取时间120min、分离温度30℃、CO_2流速为20g/min，分离压力为10MPa。

Results In the distal two - thirds of the upper arm, branches of the median nerve constantly formed three fascicular groups. The anterior part of nerve trunk hosted branches to the pronator teres and the flexor carpi radialis. The posterior part of nerve trunk contained the anterior interosseous nerve and branches to the palmaris longus muscle. Branches to the hand and to the flexor digitorum superficialis which was the main trunk of the median nerve at the proximal forearm were grouped to form the middle part.

结果 在臂中、下段，正中神经的分支恒定地组成3个神经束组：旋前圆肌肌支和桡侧腕屈肌肌支束组在神经干的前方，骨间前神经和掌长肌肌支束组在神经干的后方，中间束组是由指浅屈肌肌支和手部分支组成的正中神经前臂主干的近段。

Cell sap and plasma to maintain a constant moisture on tissue fluid, tissue fluid, so the water is not fixed.

细胞液和血浆的水分保持恒定依靠组织液，所以组织液的水分并非固定不变。

In restricted feeding, the calories needed to maintain constant weight are higher at the younger chronological age.

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
