使维持

Renegotiating pays full tribute to life's inevitable changes and says that we deem our friendships worthy of preserving.

这种重新的对待是无常的世事所需，同时也使我们相信我们之间的友谊是值得维持下去的。

The results showed: decapitation and suckering agents treatment can significantly increase leaves and leaf area index at topping later stage,enhanced chlorophyll content,extended the function of leaves,improved photosynthetic potential at the topping mid and later stage,and promoted a...

结果表明，打顶+抑芽敏处理可明显增加打顶后期单株叶数和叶面积指数，提高叶绿素含量，延长叶片功能期，增强打顶中后期光合势，促进后期净同化率和群体生长率增长，使打顶中后期光合特性维持在较高水平；打顶+人工抹芽和打顶处理也在一定程度上改善了生育后期光合特性，而抑芽敏处理对光合特性影响不明显。

That is why some hydrophobic ingredients should be added in order to made floating tablet with ideal floating duration other than decreasing the tableting pressure alone.According to the eroding kinetics, the floating tablet made of HPMC with greater viscosity as K100 MCR and K15 MCR is better than that made of HPMC E 15 LV. The erosion of the tablet made of HPMC E 15LV followed the first order kinetics. 20% of the tablet eroded with 4 hours which is 22 times that of the tablet made of HPMC K 100 MCR. The fast erosion of the tablet made of HPMC E15 LV led to quick buoyancy decrease. The quick swelling of floating tablet made of CMC-Na led to quicker water uptake.

溶蚀动力学表明，以高粘度HPMC K100MCR和K15 MCR制备的漂浮片，其漂浮性能要优于低粘度的HPMC如E15-LV，后者的溶蚀符合一级动力学规律，4小时内片面溶蚀达20％，溶蚀速度比前者大22倍，由于速度太快，漂浮制剂的漂浮力因此会迅速降低；高分子材料CMC-Na制备的漂浮片，虽然遇水后迅速膨胀使体积增大，但是，由于水渗入的速度大于体积膨胀的速度，因此不能产生足够的浮力和维持理想的持续浮力，另外，这种材料制备的漂浮片的溶蚀速度太快，4小时内片面溶蚀达30％，漂浮制剂的漂浮力也因此会迅速降低。

The management and maintenance of air condi-tioning equipments in the air conditioning train should be strengthened,so that they could be enabled to achieve the good running status,the function of increase degree of humidity of the air conditioning equip-ments should be started when heating in winter;and ventilates and air exchange of air conditioning pas-senger train waited for further improvement to maintain good air quality.

应加强空调列车空调设备的管理和保养，使其能够达到良好运行状态，在冬季取暖时应开启空调设备的加湿功能；要维持良好的空气质量，空调旅客列车的通风换气有待进一步改善。

This type of B vitamin helps release energy from food and also keeps nerve and brain cells nice and healthy.

这种类型的B族维生素有助于释放来自食物的能量并且也可以使神经和脑细胞维持健康。

Under the second assumption, collusion gets harder to sustain when tariff barriers fall and foreign producers not in the cartel offer their wares at more competitive prices; erstwhile loyalists of the cartel abandon that ship and try instead to make their activities as efficient as possible within a larger and more competitive market.

在第二个假设下，官商勾结当在关税壁垒减少和国外生产商不在的卡塔儿提供的越来越竞争中很难维持。息日的卡塔尔忠诚者放弃那样的想法，而是在一个更大和更具有竞争力的市场用尽可能有效的方法使其活跃起来。

However, mechanical prosthetic valve has poor biocompatibility, and biological valve is easy to degrade and to be damaged. People have studied a new material to make valve. Giant molecule materials-made no-stent bio-mitral valve with chordae tendineae is similar to normal valve.

生物瓣具有血流动力学性能优秀，不需终生抗凝等优点，但机械瓣的生物相容性较差、生物瓣易退化损坏等问题，使人们开始对新的瓣膜制作材料进行研究，使用高分子材料制成的无支架带腱索生物二尖瓣与自然瓣膜相似，可维持人体二尖瓣生理功能、左室几何形状和血流动力学。

The third passage osteoblasts were plated at the density of 5×104/ml in 75ml culture flask, twenty four hours later treatment factors were added.

许多激素及细胞因子通过调节破骨细胞和成骨细胞这两类细胞的数量和活性，使骨量维持动态平衡。

The Electric Dust Remover works like this:on the positive and negative pole which two metal curvature diameter's difference is abvious , put through the high voltage direct current and form a static electricity field in which gas is made to ionize.

电除尘器是在两个曲率半径相差较大的金属阳极和阴极上，通过高压直流电，维持一个足以使气体电离的静电场。

Quite a number of freshwater aquarists are tempted to keep marines because they see a stunning aquarium somewhere, or they realize that keeping marines is not as difficult as they first thought, or they feel they have accumulated enough experience to make the change.

相当多的淡水aquarists很想让海军陆战队员，因为他们看到一个惊人的水族馆的地方，或者他们认识到，维持海军陆战队并不困难，因为他们首先想到的，或者他们觉得自己已经积累了足够的经验，使改革。

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。

Go down on one's knees;kneel down
