History is not plasticine, it is not fabricated wilfully.

历史不是橡皮泥，容不得随意捏造。

Determination of industrial analysis, constant volume net calorific power, elementaryanalysis, plastometer indice, ash composition, grindablity, ash fusion point, ractivity,combustion and transportation performance of the 8 kinds of coal.

通过对8 种煤粉的工业分析、恒容低位发热量、元素分析、胶质层指数、灰分成分、可磨性、灰熔点、反应性、燃烧性能和输送性能的测定。

The falling of test weight and 1000-kernel weight in the treatments of fertilization are mainly related to grain plumpness.

施肥后籽粒容重与千粒重的下降主要与籽粒的饱满度有关。

The polynomial equation of heat capacity of this compound was simulated by the computer within the temperature range of

计算机拟合了在78.939~301.295K热容对温度的多项式方程。

The design, implementation, and characterization of an image-rejection double quadrature conversion mixer based on RC asymmetric polyphase filters are presented.

本文介绍了一种基于阻容多相滤波器的双正交镜像抑制混频的设计、实现和测试。

In this experiment, there was no significant difference between R and H treatment. The soil pondage of Z treatment was less than that of R and H, which indicated that Z treatment was disadvantageous to soil water infiltration under irrigation conditions because Z was covered by straw and had high density.

模式之间比较，旋耕和耙耕模式土壤贮水量差异不显著，免耕模式小于旋耕和耙耕模式，表明在灌溉条件下，免耕模式由于地表秸秆覆盖加之土壤表层容重变大，不利于土壤水分的下渗。

Soil bulk density of Z treatment was gradually increased in three years, which was significantly higher than that of C treatment in 0~20cm soil layer. 2.2 Effects of tillage systems on soil moisture content There was significantly positive correlation between soil pondage and rainfall of the same period in R, H and Z treatments, and the correlation coefficient was higher than C, especially the H treatment, its correlation coefficient was 0.70**, which reached a highly significant level, and its soil water retention was better than C.

免耕模式土壤容重在0~20cm均逐渐增高，最终显著高于常规耕作模式。2.2耕作模式对土壤水分的影响 0~20cm土层旋耕、耙耕和免耕模式土壤贮水量与同期降雨量显著正相关，相关系数皆大于常规耕作模式，耙耕相关系数为0.70**，达到极显著水平，土壤保水性好于常规耕作模式。

Some time after his moving in, which had borne a singular resemblance to the entrance of nothing at all, to borrow the memorable expression of the principal tenant, this Jondrette had said to the woman, who, like her predecessor, was at the same time portress and stair-sweeper:"Mother So-and-So, if any one should chance to come and inquire for a Pole or an Italian, or even a Spaniard, perchance, it is I."

他搬家的情形和那二房东所说的一句耐人咀嚼的话象得出奇，是"啥也没有搬进来"，我们在此把那句话借用一下。定居后不久，这容德雷特曾向那看门、扫楼梯、同时又是住户中资格最老的妇人说："我说妈妈，万一有什么人来找一个波兰人或意大利人或西班牙人，那就是我啊。"

A novel zero-voltage and zero-current resonant pole soft-switching inverter was proposed to achieve zero- voltage and zero-current switching simultaneously when main power devices turn-on and turn-off. Therefore, turn-on capacitive losses could be reduced for devices which the intrinsic capacitor value cannot be neglected. Additionally losses caused by the tail current can also be reduced, when IGBTs are used as main switches.

提出一种新型的零电压零电流谐振极型软开关逆变器，可以在主功率器件开通和关断时，同时实现零电压和零电流，因此对于内部电容不能忽略的器件，可减小容性开通损耗，当绝缘栅双极型晶体管(insulated gate bipolar transistor，IGBT)作为主功率器件时，也可减小拖尾电流引起的损耗。

However, there lies a particular air leakage problem of revolving type air preheater, which will lead to serious energy waste.

但是容克式空气预热器有一个独特的漏风问题，空预器漏风会引起严重的能源浪费。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
