在...条件下

We deal with the biharmonic equation and proved that under our assumptions, the week solution of the natural boundary value problem strongly converges (in H~2) to that of the first boundary value problem.

为克服这一困难，我们用具自然边界条件的边值问题(在二阶椭圆型方程情形为第三边值问题)去逼近相应的第一边值问题，并以重调和方程为例，证明了在一定条件下，其具自然边界条件的边值问题的弱解在H~2的意义下强收敛到相应的第一边值问题的弱解。

Effects of no- till in the different cover on conditions on crop yield in different cover on conditions were studied in dry land in the middle of the Loess Plateau, DingXi. Results showed that under the no-till form, Pea general increase output, agricultural input costs have decreased significantly , the average saves 810 Yuan / hm2; Under the different cover condition, the net income separately increases 1175.45, 1682.70, 968.25 Yuan / hm2, the economic efficiency is obvious.

本文通过在定西旱地农业地区实施保护性耕作，对免耕在不同覆盖条件下的豌豆产量进行了试验研究，结果表明：在免耕措施下，豌豆产量普遍增加，农业成本投入得到明显降低，平均节约810元/hm2；在不覆盖、秸秆覆盖和地膜覆盖的条件下，纯收入分别增加1175.45、1682.70、968.25元/ hm2。

An annual is best known as a plant that completes it's life cycle in a single season. Hardy annuals can survive cold temperatures and some light frost, while tender annuals cannot tolerate cold temperatures and should be planted only after there is no more danger of frost. Half-hardy annuals can tolerate some cold temperatures, but are usually killed by frost. Annuals make excellent space fillers for the perennial garden.

一年生植物最显著的一个特点就是它在一个季节内完成它的生命轮回，耐寒的一年生植物能够在低温和轻微霜冻的条件下生存，但是幼嫩的一年生植物不能忍受低温，他们只能在没有霜冻危险的条件下种植，半耐寒型一年生植物能够经受一些低温条件的考验，但是通常他们因为霜冻死亡，一年生植物能够为多年一成不变的庭院创造一个很出色的空间。

A combination analysis of SIP and in situ microbiological methods was applied on the anaerobic digestion of biomass organics suffering from severe acids inhibition. The studies found that accumulated acids were degraded mainly by Methanosarcina firstly with acetoclastic pathway and then with hydrogenotrophic pathway under mesophilic condition, whereas acids were mainly degraded to methane by the tandem reactions of syntrophic acetate oxidation and hydrogenotrophic methanogenesis under thermophilic condition.

联合应用稳定同位素表征技术和微生态原位表征方法，对高浓度有机酸胁迫条件下的生物质类有机物厌氧发酵甲烷化途径的研究结果表明，面临高浓度有机酸迅速累积的环境，中温发酵条件下，优势菌种为甲烷八叠球菌，依时间次序，通过乙酸发酵和氢营养型途径利用累积的有机酸产生甲烷；而在高温条件下，有机酸则通过乙酸氧化和氢营养型甲烷化途径的串联反应被降解。

Results of experiments under different conditions show that, compared with arc electrical signal and arc light signal, arc spectrum signal is of more advantageous property. It can not only detect short-circuit metal transfer, but also more effectively detect droplet in free transfer mode than electrical signal. It can not only detect the droplet transfer in the CO〓 welding, but also can detect spray transfer in Ar welding with advantage over arc light signal. Especially, its outstanding capability of detecting steam spray transfer where other approaches fail, shows that are spectrum information has the utmost signal quality in metal droplet transfer detecting.

多种工艺条件下的对比实验表明，与电弧电信号及光强信号相比，电弧光谱信号具有更为优越的信号品质，其不仅可以检测熔滴短路过渡而且优于电信号可以有效地检测自由过渡；不仅可以检测活性气体保护条件下的熔滴过渡，而且优于光强信号可以检测惰性气体保护条件下的喷射过渡，特别是其可以实现熔滴射流过渡的检测，解决了这一用其它信号无法克服的难题，体现出电弧光谱信息在熔滴过渡研究中所独具的优越性。

Only 1O-day pretreatment of germinated seeds at 5℃ or 10℃ was enough to enhance the floral bud differentiation in the spring variety'Duanye 13', whereas at least 20-day pretreatment was required for the promotion of floral bud differentiation in the winter variety'Yidianhong'. Non-vernalized'Duanyi 13'plants flowered 70 days after transplanting in a warm (above 15℃) and long photoperiod (16h) growth condition, but non-vernalized 'Yidianhong'plants did not flower 90 days after transplanting in the same growth condition as'Duanye 13'.

处理温度越低和/和处理时间越长，对花芽分化和开花的促进作用越明显；春性品种'短叶13'的萌动种子在5℃和10℃条件下处理10d就能显著促进其花芽分化，而且即使未经低温处理，并给予15℃以上的生长温度和16h的长日照条件，植株也能在播种后70d内开花；但冬性品种'一点红'则需要在5℃或10℃下处理20d以上方能显著促进花芽分化，若不给予低温处理，即使给予16h的长光照条件，在播种后90d也不能开花。

Large supply of non-hybrid seeds for vegetables, grains and herbs; make sure they are of the non-GMO, non-hybrid, propagating variety; also be sure to have instructions on how to harvest seeds including information on "moldering" techniques to properly collect seeds from certain plants such as tomatoes; note lastly that due to damp low-sunlight conditions many crops will not grow without growing lights and protection from rain; special research is therefore required on which crops will grow best (for instance, patty rice should grow better than wheat under damp conditions); also be sure to take into account the climactic change which results from the change in latitude due to the pole shift as a location which does not change greatly in latitude will fare better than one which falls in the vicinity of the new poles for instance; the pole shift theory presented on Zeta Talk states that the terrestrial North Pole will move to the middle of the Atlantic off the bulge of Brazil and ultimately one will need to observe the climate and the position of the sun to figure out the new latitude, and either adapt or re-locate as needed

要有许多蔬菜，谷物和草药的的非杂交种子；确信它们是非转基因，非杂交的，是用于繁殖的品种。也得确信具有怎样收获种子的指导书说明，包括&制造&技术方面的信息，以便恰当地收集某些植物的种子，例如西红柿。最后得注意，由于幽暗的低阳光环境，在没有阳光，以及没有其进行雨水防护的情况下庄稼将不会下生长。因而需要进行特别的研究，看看哪种庄稼在这种条件下生长得最好（例如，在昏暗的状况下，水稻应该比小麦生长的更好）。也要确信考虑了极移造成纬度改变，因而导致气候变化。例如，与那些位于新极点附近的地方相比，纬度变化不特别大的地方情况要好得多。齐塔人之声讲述的极移理论表明了地球北极会移动到大西洋中部的巴西隆起处。最后需要观察气候状况以及太阳的位置，以弄清楚新的纬度，根据需要，即可适应当地的条件，又可再次搬迁。

Firstly, micro-thermal calorimeters were used to qualitatively analyze the thermochemistry behaviour of reactants system under adiabatic mode; Subsequently a series of toluene nitration experiments were carried out in an isothermal reaction calorimeter to study the influences of different operating conditions such as stirring speed feeding rate and setting temperature and so on .
