Its corresponding calculation program was developed, and used to study actual change of transmission ratio during meshing process.

提出了数控加工的摆轮与针轮啮合过程实际传动比和齿侧间隙的计算方法，开发了相应的计算程序，用此程序进一步研究了啮合过程中传动比的变化规律，得出了啮合过程中传动比波动较大及步长与平均传动比不是单调关系的结论。

Here are two data points that don't jibe: The average cell phone user pays US$63 each month for their service, yet nearly half of cell users spend less than 200 minutes a month yakking on those phones.

以下是两项相当矛盾的数据：每位手机用户的平均月租费高达 63 元美金，然而其中将近一半的人每个月的通话时间不到 200 分钟。

To help understand the concept of risk, the adviser points out that the stock S1, with average annual yield of 6% over the 12 years but minimal spread on yield, would probably be less risky than stock S4, which has a 12.5% average yield but appears quite volatile.

为了帮助理解风险的概念，该顾问指出，股票一，年均收益率为6 ％的12年，但最低限度蔓延的产量，很可能是风险小于股票中四至中，有 12.5 ％的平均收益率，但似乎很不稳定。

1 The approach of LVB cannulated by passed retrograde across the aortic valve can be performed easily and reduce LV pre-load and LV work, as well as cardium oxygen consumption significally; 2 This LVB can improve coronary artery perfusion and cardiac function while AOMP can be maintained after LAD occlusion; 3 There has a potential impariment effect on the right ventricular function with excessive amount BFR (over 85%) during LVB, particularly in the present of myocardial ischemia; 4 Roller pump is not suited for a prolonged bypass because of significant damage to the blood system.

由此我们得出以下实验结论：经外周动脉逆行左室置管转流方法操作简便、迅速。能明显减少左室前负荷，减少左室作功，降低心肌耗氧量；能维持严重心脏缺血后的平均动脉压，改善冠脉循环灌注和左室功能，具有临床应用的可行性。85%以上转流率对缺血心脏的心功能有潜在的损害效应。以75%左右转流率较为合适。转子泵不适宜用作长时间转流。

The available operation range in clivus and anterior cranial base by transsphenoidal opproach was also observed during the operation under the help of neuronavigational pointer. Forty-one patients underwent sublabial, transseptal, transsphenoidal approach to the pituitary region guided by Surgical Microscope Navigation was studied. The piriform aperture was 27. 2mm±3. 1 , the origin of inferior nasal concha 30mm±4. 1, the origin of middle nasal concha 27. 9mm±4. 3. These data are important for transsphenoidal approach, because the piriform aperture and the origin of both inferior and middle nasal conchas restricted the opening width of the Hardy specula. If any distance of these bony structures was much less than the mean one, may cause inadequate opening of the specula blade and resulting dissatisfied operative field. Microadenomas or cystic tumors perhaps can be operated even in a narrow exposure, but large or giant solid adenomas may need a proper evaluation including changing the operative approach or performing a bilateral submucous inferior conchotomy or posterior ethmoidectomy firstly.

手术中还利用CT导航系统观察棒研究了经口—鼻蝶窦入路在斜坡区和前颅底能够达到的实际有效操作范围，为扩大经蝶窦入路手术在斜坡区和前颅底的应用奠定基础，在国内外尚未见同类报道。41例垂体瘤患者梨状孔平均宽度27.2mm±3.1，下鼻甲根部附着处间距30mm±4.1，中鼻甲根部附着处间距27.9mm±4.3，这是经口—鼻蝶窦入路手术中，对Hardy双瓣鼻窥器张开限制的主要骨性结构，若患者这些径线值明显小于平均值，则可能因为鼻窥器打开不充分而影响手术暴露，当然对于垂体微腺瘤和以囊变为主的垂体瘤可能影响不大，但对于大和巨大垂体瘤必须要有充分的准备，包括评估是否改用其他入路，或先行鼻甲切除再行经蝶手术。

The size of UE and LE cell is bigger in karst areas variety than in non-karst areas variety, and the arrange of palisade and spongy tissue is more compacter . Sunken stomata exist only in lower epidermis .The stomata are of renal type. Karst Area variety stomatal is density.

岩溶地区品种茎的表皮细胞厚度大于非岩溶地区品种；皮层层数较非岩溶地区品种多，细胞排列紧密，髓部不为空；在同倍显微镜下岩溶地区品种木质部脊较多，但木质部的平均长度和导管的直径比非岩溶地区的都要小。

As there were 8.69 bivalents in average occurred to be desynaptic, moreover, the most number of the desynaptic bivalents reached 12 at post diakinsis.

从品种轮回422的群体中发现一不育单株，经细胞学观察证明是发生了联会消失突变，由于该植株的花粉母细胞在减数分裂终变期晚期平均有8.69个二价体发生了联会消失，占二价体总数的72.4%，并且发生联会消失的最多二价体数目为12，根据联会消失的最多二价体数目

Both kinds of algorithms can improve the static and dynamitic characteristics of the system, and meet the design requirements.

在进行系统整体设计和软、硬件设计时，本文充分考虑了系统的实际工况，设置了手柄信号中位死区，以消除系统的误动作；同时，为适应比例阀的工作频率，利用单片机对PWM输出信号进行了分频处理，保证了通过比例阀的平均电流值不变。

One hundred and fifteen species were identified, among which coastal eurythermic species were predominant, showing obvious characteristics of subtropical population fauna. The results showed that the average abundance of phytoplankton in Shacheng Harbour was 3113.24 ind·L-1. The abundance was higher in the inner bay than that in the outer bay in horizontal distribution. The surface abundance was a little higher, but there was no significant gradient in different water layers in vertical distribution. Shannon-Wiener diversity index, Margalef richness index, Pielou evenness index and Simpson dominance index were 2.390, 2.650, 0.726 and 0.306, respectively.

结果表明，该次调查共出现浮游植物115种，种类以沿岸广温广盐性种为主，并呈现较为明显的亚热带海湾种群区系特征，浮游植物的平均丰度为3 113.24 ind·L-1；水平分布上，呈内湾高于外湾的格局；垂直分布上，表层丰度略高，不同水层的分布梯度不明显；Shannon-Wiener多样性指数、Margalef丰富度指数、Pielou均匀度指数和Simpson优势度指数分别为2.390、2.650、0.726、0.306。

The results indicate that fresh ginger contained [6]-gingerol, 1.63 ~ 2.82 mg/g, and [6]-shogaol, 0.089 ~ 0.120 mg/g, with the average [6]-gingerol content being far higher than [6]-shogaol by a factor of around twenty, and had no zingerone. In dry ginger contained zingerone, 0.054~0.140mg/g, [6]-gingerol, 1.22~6.28 mg/g, and [6]-shogaol, 1.40~2.71mg, with the average [6]-gingerol content being still higher than [6]-shogaol but only by 1.7 times.

在乾姜中，zingerone的含量在0.054至0.140 mg/g之间，[6]- gingerol的含量为1.22至6.28 mg/g，[6]-shogaol的含量为1.40至2.71mg/g，[6]- gingerol的平均含量还是高於[6]-shogaol，但不若生姜来的大，约为1.7倍左右。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
