不稳的

When he did that, he toddled and he looked a little old and unsteady on his feet, which is in direct contrast to how he comes across to his supporters.

但是有时候他也会在台上踱步，他踱步的时候不太稳，摇摇晃晃的，看上去显得有点苍老，这其实与麦凯恩想要给选民留下的印象正好相反。

Based on the relations among the stress, final wall-thickness of thin-walled tube and the characteristics of tube material, original size, curling radius along with friction condition in a axially-compressed internal inversion process on right-angled fillet die, some analytical discriminants were established for judging if a double-layered tubular piece of aluminum alloy could be steadily formed from a certain-sized round tube via internal inversion process without interference and plastic instability of tube wall, and a method was put forward for determining the maximum and minimum usable curling radius or die fillet-radius for thin-walled tubes in the process.

基于薄壁管直角圆角模轴压内翻过程中各处应力及最终壁厚与管材特性、管坯尺寸、卷曲半径及摩擦条件之间的关系，推出了判别任一铝合金双层管件可否由特定尺寸圆管稳定内翻成形而不出现管壁干涉与塑性失稳问题的解析判别式，指出了确定薄壁管圆角模内翻卷曲半径或模具圆角半径极限值的方法。

The samples were soil crust collected from Inner Mongolia, the corn growth field soil in the Scientific Park of China Agricultural University, and earthworm faeces.

最后通过灭菌与不灭菌条件下的土壤培养，采用湿筛、氯仿熏蒸等方法，进一步研究了碳源物质、土壤机械组成对菌株在土壤中的生长以及对土壤水稳性团聚体形成的影响。

Based on the instability criterion of semi-classical Maxwell -Bloch equations of single-mode optical systems, the global distribution of instability region is depicted in A-6 parameter space (△ detuning of the atoms,θ mistuning of the cavity).

本文艰据半经典Maxwell一Bloeh方程单模光学双稳系统的稳定性判据，在△一日参数平面上描绘该系统不稳定区的整体分布(这里△和日分别正比于原子与腔相对输入场的失谐度)。

Thy tacklings are loosed; they could not well strengthen their mast, they could not spread the sail: then is the prey of a great spoil divided; the lame take the prey.

赛33：23你的绳索松开。能栽稳桅杆、不能扬起篷来。时许多掳来的物被分了。腿的把掠物夺去了。

While we daren't say that the truck of this Brand is matchless in the world, any driver concerned would say:"This is the steadiest and Best truck I've ever driven."

本品牌的卡车不敢说举世无双，但司机会告诉你：&这是我开过的最稳、最好的卡车。&

Steady potentiodynamic and transient stair-step measurement demonstrate that the presence of Cu2+ can not suppress the oxidation of Fe2+ on the thiobacillus ferroxidans modified powder microelectrode.

对电极稳态及暂态过程研究表明，当Cu2+浓度在12mmol/L以下时， Cu2+的存在不会抑制Fe2+在T.f菌修饰粉末微电极上的氧化，适量Cu2+加强T.f菌氧化Fe2+的作用是在于其加快了电荷传递速率。

Thirdly, A new topology of Single Stage Asymmetrical Half-Bridge Converter with Synchronous Rectification is presented in this paper. The operation principle of the circuit is analyzed in detail. The operation principle of soft-switching and steady-state analysis is proposed.

提出了一种同步整流单级不对称半桥变换电路，对电路的工作原理作了详细的分析，特别是电路的软开关工作过程，并对电路做了稳态分析； 4。

The position of your front foot doesn't matter, it's not really used in this trick.

这个动作的成败和站位很有关系，后脚放在板尾，脚尖挂出，但脚大拇指仍要站得很稳，前脚位置关系不大，起的作用不明显，当然人的中心是在前脚上。

The company has more than 10 years 'experience of A.C.

乐清市三鼎电气科技有限公司是一家专业从事各类交直流稳压电源，UPS不间断电源，逆变电源，充电机及相关行业产品的开发、生产、销售、服务的私营企业，有10多年的交流稳压器实际生产经验，技术力量雄厚，设备先进，严格按照ISO9001-2000进行全面质量管理。

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。
